Title: Production of "igusa" like structure of acrylic polymer
Inventor: KOBASHI TOSHIYUKI
IPC: D01F6/18
Filed: 1978-12-12
Abstract: PURPOSE: A molten acrylic polymer that is prepared by a specific method is made into foamed structure, which is treated with a water-repellent finishing oil, thus producing title structure with good touch like natural igusa and high practical performance.  
     CONSTITUTION: A molten acrylic polymer that is prepared by polymerization of acrylonitrile alone or a mixture thereof with ethylenically unsaturated monomers in the presence of water at a temperature over 120°C is extruded through an orifice into the low-pressure zone to form foamed fibers, which is subsequently treated with a water-repellent finishing oil. The treatment forms wrinkles on the skin of fibers and the resulting product has good touch closely resembling to that of natural igusa and steeply increased wear resistance.

Title: Controller for electric vehicle
Inventor: NOTO YASUO
IPC: B60L15/28
Filed: 1980-11-06
Abstract: PURPOSE:To detect and process malfunction within a range of currents causing no defective commutation by resetting a microcomputer while restarting it after a fixed time when currents flowing through a DC motor become larger than voltage corresponding to the amount of an accelerator pedal worked. CONSTITUTION:An adder 160 outputs the voltage A obtained by adding predetermined voltage to accelerator signal voltage ACA corresponding to the amount of the accelerator pedal worked, and an amplifier 161 outputs voltage B corresponding to the output voltage IM of an armature current detector. A comparator 162 operates a reset circuit 163 when the output voltage B becomes larger than the output voltage A, and resets the microcomputer. A timer 164 works at the same time, and the microcomputer restarts when the functioning of the timer 164 is completed. Accordingly, the microcomputer can rapidly be returned to a normal control condition.

IPC: H01L21/3205
Filed: 1989-06-16
Abstract: PURPOSE:To prevent concentric distribution of Si to the surface of Al surface by forming a structure in which PS is formed directly under an Al pad. CONSTITUTION:A polysilicon(PS) 2 is formed in direct contact with the base of an Al pad 1, and Al 1 pad has a contact of the PS film 2 with the Al 1. Then, it is covered with a protective film 5, and the film 5 is so etched as to expose the surface of the Al 1 film. Accordingly, movement of Si 4 to the Al 1 pad surface side can be prevented by heat treating, etc., in a manufacturing step, and a distance from the Al pad surface to an Si substrate can be increased. Thus, the influence of an impact at the time of wire bonding is reduced.

Title: Production of high-fatigue strength structural member
Inventor: OKAMOTO KENJI
IPC: B22F3/00
Filed: 1992-05-22
Abstract: PURPOSE:To obtain a high-fatigue strength structural member without defects of cracks, voids, etc. CONSTITUTION:A billet is obtained from an Al alloy powder which is provided with an amorphous phase and reduced in volume on heating, the billt is heat- treated to the extent that the volumetric shrinkage rate Vs is limited to conform to 0.1%<=Vs<=7%, and then the billet is hot-extruded to produce the structural member.

Filed: 1993-06-25
Abstract: PURPOSE:To miniaturize voltage varying equipment containing a circuit to vary supply voltage by including a full-wave rectification circuit, a switching circuit and a noise filter in its constitution. CONSTITUTION:A full-wave rectifier circuit 1 consists of a diode bridge, and a switching circuit 2 is a voltage reducing circuit composed of a high speed switching element a, an oscillator b with duty varying function, a diode c, a coil d and a capacitor e. The oscillator b with duty varying function oscillates a high frequency of 25kHz-1MHz and is capable of varying duty. A noise filter 3 is to prevent noises arising from variations in current due to the on/off operation of the high speed switching element a from escaping to the power supply side. The noise filter 3 consists of a coil f and a capacitor g. As a result, noises are effectively prevented by increasing switching frequency. This makes it possible to miniaturize circuits, electronic parts and thus voltage varying equipment.

Title: Halftone recording method
Inventor: NAKAI AKIRA
IPC: G03G19/00
Filed: 1985-07-15
Abstract: PURPOSE:To obtain half tone recording of high quality which varies in halftone density smoothly by specifying the pitch between magnetism patterns and the grain size of toner. CONSTITUTION:When latent image magnetism patterns 12a, 12B - are square patterns having sides (a) or circular magnetism patterns having a diameter (a), the pitch P between the magnetism patterns 12A and 12B is set larger than (a) to prevent the latent image magnetism patterns 12A and 12B from contacting each other. Then, a gap of enough size to form a magnetism inversion area is left between the magnetism patterns 12A and 12B to eliminate such a failure that a part where no toner sticks is formed in a print image, thereby making a solid black print. Further, the particle size of magnetic toner in a use is made smaller than the distance P-a between adjacent magnetism patterns 12A and 12b and the toner is prevented from being developed connecting adjacent magnetism patterns in the middle of the formation of specific halftone density to make a solid-black print.
