| 128 | Needle thread cutter for sewing machine | JP19081695 | 1995-07-26 | JPH08173659A | 1996-07-09 | IWASE HIDEKI |
| PURPOSE: To pull tight the needle thread for a precise cutting just under the presser and to form a gap between the presser foot and the material for the prevention of cutter-caused damage by lifting the sewing machine head for the cutting. CONSTITUTION: Upon termination of sewing FUTON (a thick bedquilt) or the like, a cylinder is actuated for a sewing machine head 23 to rise and for a rotary rod 43 of a cutter mechanism 41 to rotate to an operating position B. The needle thread P in a needle 22 is cut by a cutter 50 just under a presser 22a, when the needle thread P may be unerringly cut thanks to the tension given by the elevation of the sewing machine head 23. A gap is formed between the presser foot 22a and FUTON when the sewing machine head 23 rises, which prevents the FUTON from being damaged by the cutter 50. By the use of this system, the needle thread P is firmly held by a notch 48 spreading outward, even when its position changes to and fro, and is smoothly guide to the cutter 50.

| PURPOSE: To prevent wrinkles in hem sewing for FUTON (a thick bedquilt) while moving FUTON to one direction by smoothing the process of 90° rotation from a side to another. CONSTITUTION: A sewing mechanism performs linear sewing for one side of a FUTON H being moved forward on an air table. Upon termination of this process, the center head of a rotation mechanism descends to press the FUTON H onto a sewing table 5. A clamp 54 catches a second side orthogonal to the above-sewn side, then an arm 39 makes a 90° rotation for the rotation of the FUTON H with the sewing mechanism sewing the corner. The center head next goes up for the clamp 54 to release the FUTON H, then linear sewing begins for the next hem. COPYRIGHT: (C)1996,JPO | ||||||
| 130 | Wire breakdown detector for encoder | JP27581694 | 1994-10-14 | JPH08114466A | 1996-05-07 | TANAKA TOSHIHISA |
| PURPOSE: To make it possible to detect wire breakdown and signals all the time even at any time of operation and stop when an encoder is a complementary type by providing a plurality of light emitting/photodetector elements, a power supply, an AND circuit and a NOR circuit. CONSTITUTION: When a signal line 2 is not broken, the light emitting element of the light emitting/photodetector element 1 emits the light, and the photodetector receives the light by the flowing of the current from a power supply V1 to GND through the signal line 2. Since the high logic signal is outputted under the state wherein the photodetector does not receive the light, the wire breakdown can be detected based on the output level of the element 1. When a signal line 1 is not broken, the logic signal of the photodetector in the light emitting/ photodetector element 2 becomes high when the level of the input signal from an encoder is high. Meanwhile, the detected signal of the encoder becomes the low level when the input signal is high. Therefore, when both the output level of the element 2 and the detected signal level of the encoder are high, the wire breakdown can be judged. Furthermore, all the light emitting/ photodetector elements are electrically insulated from an encoder output circuit E, and the noise from the signal line is not received.

| PURPOSE:To easily obtain a light-weight formed material having high bending strength and workability at a low cost by incorporating glassy blast furnace slag powder with a clay mineral, an alkali hydroxide and water, incorporating the obtained slurry with glassy blast furnace slag powder, clay mineral and reinforcing fiber and subjecting to hydrothermal treatment in a specific state. CONSTITUTION:This formed material is produced by incorporating glassy blast furnace slag powder with a clay mineral, an alkali hydroxide and water, subjecting the mixture to hydrothermal treatment, adding glassy blast furnace slag powder, clay mineral and reinforcing fiber to the obtained hydrate slurry, kneading and forming the mixture and subjecting to hydrothermal curing. Hydrothermal reaction of the stag with the clay mineral takes place by the addition of glassy blast furnace slag powder, clay mineral, alkali hydroxide and water, followed by hydrothermal treatment. The surface of particle is modified to porous state by this treatment to obtain light-weight particle having large specific surface area. The clay mineral plays the role of the silica source for the formation of calcium silicate hydrate. When bentonite is used as the clay mineral, water is taken into the gap between the layers of montmorillonite constituting the main mineral component of the bentonite to contribute to the reduction of weight. | ||||||
