Title: Electroviscous fluid
Inventor: KOJIMA YOSHITSUGU
IPC: C10N30/08
Filed: 1991-11-30
Abstract: PURPOSE:To provide an electroviscous fluid which does not cause any increase in a current density even when used at a temperature as high as about 100-150 deg.C and excels in heat resistance. CONSTITUTION:An electroviscous fluid prepared by dispersing electrical insulating solid particles based on a condensed polycyclic aromatic compound in an electrical insulating dispersing medium. A condensed polycyclic aromatic compound having 4 to tens of benzene rings is used. This compound has a rich electron cloud due to a large number of benzene rings and markedly develops the Winslow effect. Since it is a polymeric compound in which the benzene rings are condensed to form a rigid planar chemical structure, the thermal motion of molecules is suppressed even at high temperature, and the current density scarcely increases when a voltage is applied. Therefore, it can be effectively used in automobile devices such as clutches, shock absorbers and engine mounts to be used at a temperature as high as above 100 deg.C.

Title: Semiconductor device
Inventor: KIMURA TAKEMI
IPC: H01L27/08
Filed: 1989-12-29
Abstract: PURPOSE:To obtain a semiconductor device of high integration degree, by constituting an element isolation region formed on a semiconductor substrate surface by using a conducting layer which covers the isolation region and stretches as fast as the element region, and connecting said layer with a constant voltage source. CONSTITUTION:Between adjacent element regions 6, a region exists where element isolation regions are smaller than those of the other parts and closely neighbored to each other. On said region, a second polycrystalline Si electrode 8 is arranged, which is connected with a constant voltage source and stretches on the region 6. Even in the case of a parasitic MOS transistor whose element isolation region width is short, e.g. 0.6mum, electric conduction is not generated and the breakdown strength between elements is not deteriorated even when a supply voltage happens to change larger than or equal to 20%, because the transistor has a threshold value of about 5V. Hence the element isolation region width can be reduced, and the integration degree of an element can be increased.

Title: Intake-air controller for internal combustion engine
Inventor: MAEDA SATOSHI
IPC: F02B27/02
Filed: 1989-12-27
Abstract: PURPOSE:To lengthen an inlet pipe and lower the total height of an engine by forming a suction system with a collector, an air-intake passage, and an inlet manifold, which is formed as an integrated body together with middle-and right-and-left-air chambers. CONSTITUTION:A suction system is formed with a collector 28, air-intake passages 361 to 364 for a high engine speed, air-intake passages 371 to 374 for a low engine speed, and an inlet manifold 35, which is formed as an integrated body together with a middle air chamber 31 and right and left air chambers 29 and 30. Here, by fully closing closing-control-valves, which are arranged at run-off ports 28b and 28c situated at the right and left sides of the collector 28, the intake-air, which flowed into the collector 28, is sucked into a combustion chamber from the middle air chamber 31 via the air-intake passages 371 to 374 for the low engine speed. In this case, since the distance between the right bank the left bank is large enough, the length of the air-intake passages 371 to 374 for the low engine speed can sufficiently be lengthened. In addition, since the suction system is formed with two compact divisions and is of a flat shape, the total height of the engine can be lowered.

Title: Transmitter
Inventor: HOSODA SHIGERU
IPC: H04B1/74
Filed: 1992-12-24
Abstract: PURPOSE:To provide the transmitter with a simple switching system making switching without need of transmission/reception of a monitor alarm bit. CONSTITUTION:When a fault is detected by a transmission circuit signal is switched from the active circuit being the transmission circuit 5 to a standby circuit being a transmission circuit 6 and the transmission output in the transmission circuit 5 is stopped. Thus, an opposite transmission circuit 1 detects a fault (interruption of an input signal) and the signal is selected from the active circuit being the transmission circuit 1 into a standby circuit being a transmission circuit 2. As a result, since the changeover to a standby circuit is attained by using fault information only of its own transmitter, the changeover device is executed simply and surely without the need of transmission/reception of a monitor alarm bit.

Title: Forgery preventing method by derangement of copied image, and sheet printed matter to be used therein
Inventor: AKUTSU YOJI
IPC: B42D15/10
Filed: 1993-12-17
Abstract: PURPOSE:To prevent forgery of printed matters by randomly refracting a print image on a surface of a sheet printed matter so as to deform and derange the actual image when it is copied by a copying machine and easily discriminate it as a copied matter. CONSTITUTION:A surface 1a of a bill 1 is laminated with a transparent information sheet 2a having an irregularity on its surface for randomly refracting a printed image 4 by a transparent resin adhesive. When it is copied by a copying machine, the actual image 4 on the surface 1a of the bill 1 is refracted by a transparent resin layer 2 of the transparent resin sheet 2a, so that the actual image 4 is copied as a deformed image 4a. Thus, the copied matter becomes different from the actual image 4, so that the forged copied matter can be easily discriminated. Even when somebody tries to peel the transparent resin sheet from the image face on the sheet surface in order to print the actual image correctly, it can not be peeled without damage.

Filed: 1991-12-26
Abstract: PURPOSE:To provide a system for measuring a surface shape at high velocity with high accuracy. CONSTITUTION:A laser beam 7 passing a collimator lens 3 is cast at right angles to a surface of a target 16 sequentially through a rotary mirror 6 for scanning in an X direction, collimator lenses 10, 11, a rotary mirror 9 for scanning in a Y direction and a principal lens 15. A cast light 17 is scanned in the X and Y directions by the rotary mirrors 6 and 9. A reflected light 20 at the target 16 is condensed by the principal lens 15 and returned back in an optical path of the cast light IT to a mirror 4 with a pin hole. A returned light 21 is reflected by the mirror 4 to advance to a mirror 22 of a quadrangular pyramid. An image is surely detected by any one of PSDs 23-26 of the mirror 22 set corresponding to each mirror. This optical scanning enables high-speed measurements. The alignment of lenses becomes unnecessary because of the use of the principal lens both for projection and for receipt of light. Highly accurate measurements are achieved also because of the use of the PSDs 23-26.

Title: Method for preventing pinhole from occurring to inner bag of bag-in-box
Inventor: TAKEZAWA YASUHEI
IPC: B65D77/06
Filed: 1995-12-07
Abstract: PROBLEM TO BE SOLVED: To prevent liquid in an inner bag from surging, and to prevent pinholes from being made to the inner bag because of repeated bending and rubbing by a method wherein the upper part of the inner bag of a bag-in-box is pressed with a pressing plate that follows lowering of liquid level that occurs, following swelling of the bag at its trunk. SOLUTION: A pressing plate 6 serving as a lid is mounted directly on the upper part of an inner bag 2, and a pressing member 7 is laid on top of the pressing plate, and the upper part of the pressing member 7 is bound crosswise with a band 8 and fixation is made therewith. Springs 9 are fixed on four positions at the underside of the pressing member 7, and the pressing plate 6 presses the inner bag 2 with force of the springs 9. Effective range of the spring 9 is set at an extent larger than the distance of lowering of the level of the liquid that occurs when the bag swells at its trunk.  As the pressing plate 6 constantly presses the inner bag 2 with expansion of the springs 9 even though the level of the liquid is lowered with the bag swelled at its trunk during transportation, a vacant space is not produced in the bag-in-box, preventing the liquid from surging during transportation. Furthermore, pinholes that are liable to be produced by repeated bending or rubbing on contacting with a corrugated board box can be prevented, resulting in prevention of bag breaking.
