281	Consumable ignitor for solid propellant rocket motor	JP24990090	1990-09-18	JPH03130566A	1991-06-04	HERUMAN FUEDE RAIN SHIEIYA; GUIIDO BORUZO; SARUBATOORE GIBIRISUKO
PURPOSE: To enhance propulsion efficiency by arranging an ignitor inside a case provided with a combustible charge on its internal surface, and making the ignitor consumable during the propulsion of a rocket motor, the ignitor containing an initiator comprising a charge stored in a small container. CONSTITUTION: A solid propellant rocket motor 100 of the type intended for space use has a consumable ignitor 110 and a solid propellant 101. The ignitor 110 has a substantially spherical thin case 111 and a combustible charge 112 formed as a layer lining the internal surface of the case 111 and defining a combustion chamber 113. The case 111 has a plurality of holes 115* in the cylindrical skirts 11b, 111b of two semi-domes 111 a,111a and ignition devices in the form of small containers 120 storing charges 121 are mounted in the holes 115', 115". The other holes 115 are used as sonic throats, having the action to ease the high and low impacts of combustion. COPYRIGHT: (C)1991,JPO

285	Optical proximity fuze	JP7871289	1989-03-31	JPH01312400A	1989-12-18	BEA DOU KOA
PURPOSE: To prevent a target from being misjudged, by providing at least two light transmitters, by providing one light receiver to each transmitter, by repeatedly, continuously, and simultaneously measuring target distance by both the receivers, and by performing ignition when a response is simultaneously made. CONSTITUTION: Each of two transmitters 20 emits each of light transmission cone or conical light beams S1 and S2 pulsively. Two receivers 21 can perform detection only when reflected light exists inside both of light reception cones E1 and E2. Therefore, both the receivers 21 can identify a target only when the target exists in both of transmission and reception superimposition regions B1 and B2, thus preventing target misjudgment where a small object such as a fragment and a rain drop existing in the superimposition region B1 or B2 is the target. More specifically, since such objects are not recognized, ignition is not started by a proximity fuze. COPYRIGHT: (C)1989,JPO
286	Mechanical acceleration sensor	JP10265388	1988-04-27	JPH01274069A	1989-11-01	MOTOSAWA YASUKI
PURPOSE: To make it possible to make setting easy and to simplify the structure of a sensor, by supporting swingably a weight and an actuating arm, respectively, and swing the weight with inertial force. CONSTITUTION: At the normal time, an actuating arm 5 is engaged with a weight 4. Under this state, the arm 5 is kept at an initial position by the energizing force of a toggle spring 12. When acceleration exceeding a specified value is received, the weight 4 is swinged against the energizing force of the spring 12. The arm 5 which is engaged with the weight is also swinged together. When, the arm 5 exceeds the neutral position of the spring 12, the energizing direction of the spring 12 is inverted, and the arm 5 is energized in the moving direction. Therefore, the arm 5 is separated from the weight 4 and quickly swinged. An actuating member 9 comes into contact with an output device 15 and actuates the device 15. Since the weight 4 and the arm 5 are made to swing, resistance against the motion is almost negligible. The weight 4 is controlled and the arm 5 is driven with one spring 12.

289	Electronic type time delay blasting cap	JP25977987	1987-10-16	JPH01102300A	1989-04-19	OCHI KOJI; HARADA AKIHIDE
PURPOSE: To enable an abnormal state of resistance value of an igniting resistor to be confirmed and inspected after a blasting cap is completed as a product by a method wherein a bypass is arranged, a measuring current is flowed in an igniting resistor, a voltage generated between both ends of the igniting resistor is detected and a resistance value of the igniting resistor is measured. CONSTITUTION: When a measuring voltage having such a value as one not operating a delay circuit 3 is supplied from a DC power supply 7 to input terminals P ₁, P ₂ of a blasting cap through leg lines 2A, 2B, a measuring electrical current flows in an igniting resistor 4 through a bypass resistor 5. At this time, a high potential side of the igniting resistor is coupled to a metallic cylindrical section 1b through a protection resistor 6, so that if a voltage measuring circuit 8 is connected between the metallic cylinder 1b and the leg line 2B, a terminal voltage of the igniting resistor 4 can be measured indirectly, thereby the resistance value of the igniting resistor 4 can be calculated.

290	Device for adjusting counter for operating time fuse of projectile in digital system	JP17930388	1988-07-20	JPS6441799A	1989-02-14	GOTSUTOUIN ETSUTERU; MARUKUSU ZUUTAA
PURPOSE: To enable transmitting a number of pulses within a short time after their passage through the transmitter coil by using double pulses for the pulse transmitted from the transmitter coil located at the muzzle to the receiver coil in the projectile. CONSTITUTION: Double pulses are used when the muzzle velocity of a projectile is measured, the pulse is transmitted from the transmitter coil 16 fixed to the front of the muzzle 10, and a counter 32 in a projectile 22 is inductively adjusted through the receiver coil 23. The positive voltage +U is used for the first part of a signal 1 and a negative voltage, -U for the second part. A negative voltage -U is used for the first part of signal 0 and a positive voltage +U, for the second part. And provided that both the positive pulse +U and the negative pulse -U continue, for example, for 400 nanoseconds, the time necessary for the double pulse becomes 800 nanoseconds and, besides, 800 nanoseconds is sufficient for the dead time in the single double pulse. That is, it is possible for the dead time to be as short as one tenth in the comparison with the past.
