| PURPOSE: To reduce the reflectivity of a projector tube at the interface between the tube and a liquid for cooling the front surface of the tube so as to achieve increased image contrast, and prevent any breakage of the projector tube by using a specified liquid mixture of glycerol and ethylene glycol as the cooling liquid. CONSTITUTION: A cooling liquid (A) is poured through the hole 2i of a frame 2 into the space surrounded by a diaphragm 15, the projection surface of a projector tube 1 and the curved surface of a lens 1 to fill the space with the liquid (A). The cooling liquid (A) is a mixture of ethylene glycol and 20W40wt% of glycerol. Use of the cooling liquid (A) reduces a total reflectivity of the projector tube 1 and greatly increases the image contrast. Since the vapor pressure of glycerol is very small, it is possible to prevent any breakage of the projector tube 1 and a lens 11 resulting from pressure by making the vapor pressure of the cooling liquid (A) smaller than that of a conventional cooling liquid.

| PURPOSE:To reduce deformation of shadowmask the to temperature rise by applying a film for absorbing the electron beam to be reflected from shadowmask onto the inner magnetic shieldboard facing against the shieldboard. CONSTITUTION:An electron beam projected from an electron gun 2 is deflected through a deflection yoke 7 then passed through the slit of shadowmask 3 having color selecting function and strikes against a fluorescent stripe thus to produce a color picture image onto a fluorescent screen 5. Here, a film composed of such element as titanium, manganese, magnetium, etc. having lower density than the shieldboard 8 is applied onto the surface of inner magnetic shieldboard 8 typically composed of low carbon steel plate and arranged while facing against the shadowmask 3. Consequently, the majority of electron beam reflected from the shadowmask 3 can be absorbed to reduce temperature rise of shadowmask 3 thus to reduce the color shift of picture image. | ||||||

| PURPOSE:To prevent the breakage of a projection picture tube by filling a liquid containing silicone oil in the space surrounded by the face plate of the projection picture tube and a metallic plate and a transparent plate which are fixed to the front surface of the face plate so as to efficiently cool the projection tube by the liquid. CONSTITUTION:After a metallic plate 3 having a central window is fixed to the face plate 2 of a projection picture tube 1, a transparent plate 9 is fixed to the metallic plate 3 by the use of an adhesive 10. After that, silicone oil is filled in a sealed space 12 surrounded by the face plate 2, the metallic plate 3 and the transparent plate 9, thereby making a liquid-cooled projection picture tube device for a television picture projection device. By thus using silicone oil which easily causes convection, has a good thermal conductivity and minimally evaporates, the projection picture tube 1 is not broken even when it is made to emit light with great input electric power and high luminance. Consequently, it is possible to improve the reliability of the liquid-cooled projection picture tube device. | ||||||

| PURPOSE:To improve the cooling effect of face plate by filling the space between the face plate of projection tube and the space surrounded by a metal plate fixed at the front side thereof and the transparent plate with a liquid containing a propylene gricol. CONSTITUTION:A television picture projection apparatus is formed by fixing a metal plate 13 such as aluminium plate having a window at the center to the external surface of face plate 12 of projection tube 11 with a bonding agent 14 and attaching metal 15, fixing a transparent plate 19 such as a glass to the front side thereof with a bonding agent 20 and filling the hermetically sealed space 22 between them with a 100wt% propylene gricol as the liquid. The heat from the face plate 12 is transmitted to the metal plate 13 through convection of the liquid and is then radiated to the outside. Therefore, since the solidifying point of propylene gricol is sufficiently low, the convection occurs even in the cold region assuring good cooling property and thereby breakdown of projection tube can be prevented. | ||||||

| PURPOSE:To check flowing out of an alkaline metal while preventing leakage of a liquid coolant due to chemical reaction of the coolant to an adhesive and a panel as well as to prevent generation of cloudiness by providing an SnO2 film on the contact surface of a phosphor screen panel and a front glass with the liquid coolant. CONSTITUTION:An SnO2 film 6 is formed while coating the surface side, where a phosphor screen panel 1 and a front glass 2 contact with a coolant 5, with an SnO2 film for instance,by a spraying method or a CVD method to the thickness of the range 5-5,000Angstrom . According to said constitution, flowing out of an alkaline metal due to moisture of the liquid coolant 5 from the surfaces of the phosphor screen panel 1 and the front glass 2 can be checked while preventing generation of alkaline hydroxide. | ||||||

| PURPOSE:To increase brightness of a phosphor while suppressing temperature rise of a panel by fixing a radiation plate while making it to contact with the base for mounting a cathode-ray tube in order to further improve thermal radiation from the base for mounting the cathode-ray tube. CONSTITUTION:A radiation plate 10 is in the shape of a wide frame seen from the side of a transparent plate 5 while being provided with lug holes 10a on the four corners and the radiation plate 10 is made to directly contact with the base for mounting a cathode-ray tube for being fixed to the base for mounting the cathode-ray tube while inserting screws into the lug holes 10a for tightening. In this way, by contacting with the radiation plate 10 and the base 8 for mounting the cathode-ray tube while setting up a contact area sufficiently large, the heat of the radiation plate 10 is fully thermally conducted to the base for mounting the cathode ray-tube so that the heat from the panel 1a is radiated extremely good through the radiation plate 10 and the base 8 for mounting the cathode-ray tube. | ||||||

| PURPOSE:To enhance the effect of heat radiation, by placing an RTV rubber of high thermal conductivity as a filler between a heat radiating plate and a metal band wound around the faceplate of a cathode-ray tube. CONSTITUTION:An X-ray shield 7 made of metal is provided around the faceplate 1 of a cathode-ray tube in order to block X-rays. The tube is reinforced by a metal band 6 for preventing the glass of the tube from scattering away at the time of bursting and compression of the tube. An RTV rubber 8 of high thermal conductivity is placed as a filler between a heat radiating plate 4 and one or both of the metal band 6 and the X-ray shield 7 so that the plate 4, the band 6 and the shield 7 are thermally connected to each other. As a result, the band 6 and the shield 7 can function to radiate heat so that the fluorescent faceplate 1 cannot crack even if an electron beam of higher energy than with the radiation of heat only by the heat radiating plate 4 is projected to the faceplate. For that reason, a high-luminance image can be made. | ||||||

| PURPOSE:To improve the efficiency of assembling a picture tube of the liquid- cooling projection type and achieve uniform adhesive force by installing a spacer only in the adhesive layer located between the picture tube and a radiator plate. CONSTITUTION:After a radiator plate 3 is installed outside the panel 1a of a picture tube 1 with an adhesive layer 2 and a corner spacer 7 installed in the adhesive layer 2 interposed, a transparent plate 5 is installed over the plate 3 with an adhesive layer 4 interposed. Next, a jig 10 with a given dimensions having a radiator-plate-receiving surface 10a and a transparent-plate-receiving surface 10b is placed on the transparent plate 5 and then pressed toward the panel 1a. When the surface 10a touches the plate 3, the adhesive layer 4 is pressed into a given restricted thickness. And, when the jig 10 is further pressed toward the panel 1a, the adhesive layer 2 is compressed until its thickness becomes that of the spacer 7. Because of the above structure, it is only necessary to install the spacer 7 in the adhesive layer 2. Furthermore, since the adhesive layer 4 does not contain any spacer, the width of the adhesive layer 4 becomes uniform. | ||||||

| PURPOSE:To completely prevent foreign material to enter the cooling medium, by forming an enlarged section on the upper part of the cooling medium inlet opening, and by placing the packing for sealing between the end of the stopper and the enlarged section. CONSTITUTION:An enlarged section 10b is formed at the upper part of an inlet opening 10a of a metal bracket 10, and an internal thread 10c is made on the upper part of the enlarged section 10b. A packing for sealing 11 is placed in the enlarged section 10b and a stopper with an external thread 12 is screwed into the internal thread 10c. Thus, by placing the packing for sealing 11 between the enlarged section 10b formed at the upper part of the inlet opening 10a and the end of the external thread 12, the ground chips formed when the stopper with the external thread 12 is screwed onto the internal thread 10c of the metal bracket 10 is prevented from entering the cooling medium by the packing 11. Thus, the entrance of any foreign material to the cooling medium is completely prevented. | ||||||
