Title: Production of composite fiber and sheet using the fiber
Inventor: MATSUDA YUJI
IPC: D21H13/00
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To obtain a composite fiber apart from agglomeration and entanglement and allowing solid particles on the surface of the fiber to fulfill its function sufficiently independently of the kind of the fiber by specifying the length and the axial ratio of the fiber and fixing the solid particles onto the surface of the fiber by an impingement method using a high-speed air stream. SOLUTION: This method for producing a composite fiber is to fix solid particles with a mean particle size of 0.1 to 100 μm onto the surface of a fiber with a weight average fiber length of 0.1 to 5 mm and axial ratio of 5 to 300 by an impingement method using a high-speed air stream in a dry manner. The usable fiber is not limited to a sort of hydrophilic fiber, and the resultant composite fiber needs no dry process, bears the solid particles on the surface thereof in high ratio, and is useful for production of e.g. a thin film with high opacity.

Title: Movable mirror unit for michelson interferometer and unified type microscopic fourier infrared spectrophotometer using such unit and interferometer
Inventor: KAWASAKI KAZUHIRO
IPC: G01J3/45
Filed: 1988-10-08
Abstract: PURPOSE:To reduce the size of a unified type microscopic Fourier infrared spectrophotometer by using the movable mirror unit for the Michelson interferometer which can scan the movable mirror stably with good reproducibility. CONSTITUTION:Corner cubes 20a and 20b of the movable mirror unit 21 are fixed back to back on the slanting surface of a mirror base 22. Further, the upper end part of a pendulum column 24 is coupled with the lower end part of a support column 28 through a cross leaf spring 26. When an AC current supplied to a voice coil 42, the column 24 vibrates around nearby the intersection of the spring 26 with an electromagnetic force operating between the coil 24 and a magnet 38. Luminous flux which strikes on the mirror 20a through a hole 32a is reflected in the opposite direction and luminous flux which strikes on the mirror 20b through a holes 32b is reflected in the opposite direction. Thus, the column 23 is longitudinally long and a driving device is provided below it, so the occupation area of the unit 21 is reducible. Then the unified type microscopic Fourier infrared spectrophotometer is constituted by uniting an infrared light source, the Michelson interferometer equipped with the movable mirror unit, an infrared microscope, and a photodetector together.

Title: Bearing mechanism for rotary machine
Inventor: TAKANO KAZURO
IPC: F04B27/08
Filed: 1990-09-25
Abstract: PURPOSE:To prevent the generation of noise and to reduce the number of assembling processes by providing a gap regulating means to restore a gap between a thrust bearing and a thrust seat to zero by means of slip torque exerted on the gap therebetween. CONSTITUTION:Since the friction factors of the surface of thrust seats 8 and 8a and the screw surface of a screw means 81 are regulated, slip torque between thrust bearings 7 and 7a and the thrust seats 8 and 8a is increased together with a thrust load increased by an impulsive force. Therefore, the thrust seats 8 and 8a are rotated by means of the increasing slip torque and protruded in the direction thrust bearings 7 and 7a through the screw action of the screw means 81, a gap therebetween is automatically reduced to zero, and the generation of noise is reduced. Besides, since when the gap is reduced to zero, no impulsive force due to collision is generated, slip torque by means of which the thrust seats 8 and 8a are only rotated is not generated. This constitution prevents a thrust seat from protruding more than necessary and the generation of an excessive thrust load, and maintains a gap at a constantly optimum value.

Title: Coil element and filter circuit using same
Inventor: AMA NOBUYUKI
IPC: H01F27/00
Filed: 1988-10-07
Abstract: PURPOSE:To obtain filtering characteristics stable to temperature change by using a wire of shape memory alloy which stores the shape capable of offsetting fluctuation of inductance by temperature change so as to form a coil element. CONSTITUTION:Shape memory alloy being line material of a coil element which is attached to a board 2 exhibits hysteresis characteristics in which the deflection to temperature is saturated on the high temperature side and on the low temperature side, respectively. The coil element 1 stores each shape at normal temperature, when initial setting is done, at low temperature, and at high temperature. And it is set so that the inductances in those shapes may be equal to the inductance in the shape at initial setting. That is, at low temperature at least the length becomes shorter than that at initial setting, and at high temperature at least the length becomes longer than that at initial setting. For this reason, even if the temperature of the coil element 1 changes, it offsets the amounts of fluctuation of inductance by that temperature change and the inductance never fluctuates.

Abstract: PROBLEM TO BE SOLVED: To provide a redundancy processing device of high cost performance by reducing a required buffer memory capacity. SOLUTION: Row and column address fail counters 101 and 102 count the number of fail address of each row and column address, respectively, based on the row address, the column address and fail information of the addresses transferred from a buffer memory of a tester. A row or column line fail detector 103 or 104 judges line fail from the count value, and in a row or column line fail flag 105 or 106, a flag '1' is set in the applicable row address or column address. A writing control part 107 stores fail addresses, in order, in a buffer memory 108. But, when a line fail is defined, writing is not performed for the applicable row or column fail address from the point. When it is judged that the fail addresses exceed the number of relievable maximum storage by the writing control part, a flag is set in a limit over flag 109.

IPC: B65H1/12
Filed: 1994-09-26
Abstract: PURPOSE: To stably feed a paper sheet by means of a simple mechanism by supporting the middle point of a loading plate for loading a recording paper sheet by means of a supporting shaft capably of being fluctuated. CONSTITUTION: A hopper plate 11 loading recording paper P is received in a hopper 1. A supporting shaft 13 is fitted to the middle point of length in the paper feed direction of the hopper plate 11, and the supporting shaft 13 is rotationally movably fitted to a bearing 15 provided in the hopper 1. One end part of the hopper plate 11 is pressed upward from the lower part by a spring 17, and hence the recording paper P is pressed with a pick roller 6 by fixed pressing force. In this way, the hopper plate 11 can be fluctuated centering around the supporting shaft 13, in addition the supporting shaft 13 is positioned on the middle of the plate 11, hence the weight of the recording paper P is cancelled, and the weight of the recording paper P is not applied to the spring 17.  Consequently, even when the whole weight of the recording paper P is changed, the pressing force of the spring 17 against the recording paper P is not changed, and hence the paper can be stably fed.

Abstract: PROBLEM TO BE SOLVED: To improve characteristics at a hot temperature for higher generated output, by making a distance between the claw parts of claw-shaped poles disposed so as to face each other, in which a permanent magnet is disposed, smaller than a distance between the claw parts of claw-shaped poles disposed so as to face each other, in which the permanent magnet is not disposed. SOLUTION: With a distance between poles of a claw part 12X1 of a claw- shaped pole 12X and a claw part 12Y1 of a claw-shaped pole 12Y taken as L1, a distance between the poles of a claw part 12X2 of the claw-shaped pole 12X and the claw part 12Y1 of the claw-shaped pole 12Y taken as L2, the distance L1 is set so as to be smaller than the distance L2. A permanent magnet 18 is disposed between the claw-shaped poles of the smaller side of the distance L1, and leakage flux between the claw-shaped poles is reduced. Between the largely opened claw-shaped poles of the distance L2, the leakage flux is decreased, and the permanent magnet is not disposed.  Therefore, cooling wind can pass through easily so that it may accelerate cooling of a field winding 16 disposed on the inner periphery between the claw-shaped poles, thus enabling to suppress degradation of generating characteristics at a hot temperature.
