Title: Optical disk device
Inventor: ICHIKAWA SHIRO
IPC: G11B7/14
Filed: 1990-01-25
Abstract: PURPOSE:To record information with high reliability in a short time for processing data by providing a disk rotating device which rotates two disk media coaxially arranged at some intervals and an optical head arranged between the optical disk media. CONSTITUTION:One of two-divided light sources is reflected by a mirror 281 and supplied to a 1st objective lens 21. At the same time, the other light source is reflected by mirrors 282 and 283 respectively and supplied to a 2nd objective lens 24. The light projected by the lens 21 is reflected by the surface of the optical disk medium 1 and enters a sensor 291 again via the lens 21 and the mirror 281 and a half mirror 272. An actuator 22 for driving the lens 21 is controlled by forming a servo loop of focusing and tracking error signals obtained by a sensor 291. The light projected from the lens 24 is reflected by the surface of the medium 1' and enters the sensor 292 again via the lens 24, the mirror 283 and the half mirror 273. An actuator 23 for driving the lens 24 is controlled with the signal of the sensor 292.

Title: Diaphragm for speaker and its production
Inventor: FUJIMORI NAOHARU
IPC: H04R7/02
Filed: 1983-02-03
Abstract: PURPOSE:To obtain superior conversion characteristics at a high range of voice by using diamond or amorphous carbon as a diaphragm substance. CONSTITUTION:When it is defined that Young's modulus is E and specific gravity is rho, a diaphragm material with higher E/rho has superior conversion characteristics at a high singing range. Diamond has the highest modulus of elasticity and its E/rho reaches 300dyn cm/g. An amorphous carbon film also has similar property as a diamond film and its Young's modulus E and specific gravity rho are almost similar to that of diamond. In order to accomplish said purpose, a diamond film or an amorphous carbon film are evaporated on the surface of a base body having an object diaphragm shape and the base material is removed, so that a diaphragm consisting of diamond or amorphous carbon can be obtained. It is preferable to use Si as a base body.

Title: Impact buffer sheet
Inventor: NAKAGAWA MASAHIRO
IPC: B32B27/30
Filed: 1989-01-26
Abstract: PURPOSE:To relax impact by means of elasticity of a foaming resin sheet, increase tensile strength of the foamed resin sheet by means of buried-in resin sheet and increase the strength of the whole of an impact buffer sheet by laminating a foamed resin sheet mixed with flake-like powder with a synthetic resin sheet between facing surface layers. CONSTITUTION:Buffer sheets 6 constituted by foamed resin sheets 3, 4 composed of urethane mixed with flake-like powder, stylene, butadiene, rubber and the like inserting a synthetic resin sheet 5 of a material of 5X10<6>N/m<2> or more Young's modules such as vinyl chloride and acryl interposed and laminated between surface layers 1, 2. The impact time of impact force applied to the surface layers 1, 2 becomes longer by the elasticity of the foamed sheets 3, 4, and its maximum impact force becomes smaller, provided impulse is constant. Also, repulsion coefficient grows smaller by energy loss because of viscosity of foamed sheets 3, 4, and the maximum impact force grows smaller. The noise following the impact is also reduced by the relaxed impact force, and tensile strength becomes larger than the case of foamed resin sheets only.

Title: Flashover detecting method for ignition plug and detection alarm device
Inventor: IMAMURA TOMOAKI
IPC: F02D45/00
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To detect generation of flashover not by judgment of a user of an engine and but at the time of an engine operation. SOLUTION: This device detects light generated by flashover of an ignition plug by a photosensor arranged in the vicinity of the ignition plug at first (SP 1). Next, whether the light detected exceeds a preliminarily set light detection level or not is discriminated (SP 2). When it is discriminated that light detected exceeds the preliminarily set light detection level, generation of flashover is notified to a user by an alarm lamp (SP 3). By this detecting method, generation of flashover which is affected by an operation condition and has no reproducibility can be exactly detected.

Title: Rotary drum type sand classifier
Inventor: ISHIDA AKIRA
IPC: B03B5/56
Filed: 1979-02-17
Abstract: PURPOSE: To enhance classification efficiency and miniaturize the apparatus by providing a strap plate for down-flowing turbid water classification within the drum body in the rotary drum type sand classifier equipped with the spiral form sand feed vanes provided on the inside circumferential surface of the horizontally supported and rotating drum.  
     CONSTITUTION: The turbid water charged into the turbid water conduit 11 of the rotating drum body 1 collides against a strap plate 15 from a release and 11' and flows down along one side of the strap plate 15 in spacing 14. The most water contents fly in the arrow W along the diffraction of the circumferential edge part 15' and fly to an overflow port 9. On the other hand, sand sediments in the arrow S direction owing to flowing-down by gravity. The sand is further transferred in the cover plate 8 direction by sand feed vanes 19, is scooped up by a perforated plate 20 and is discharged through a sand outlet 10. At the time when the turbid water flows down, the water and sand are classified to a certain degree and therefore the settling and separation of the sand are rapidly accomplished, thus the higher classification efficiency and smaller apparatus are achieved.

Abstract: PURPOSE:To deform a tubular seal part elastically without damaging its outside appearance and with maintenance of the best sealing property by molding the first door seal piece provided with an insert groove at its tubular seal part and the second door seal piece provided with a solid part integratedlly with each other without using any joint. CONSTITUTION:A door seal material 2 consists of the first door seal piece 2a and the second door seal piece 2b which have different cross sections are integrally molded without any joint. A deep insert groove 20 is installed along the longitudinal direction to insert the edge 18 of a decorative material 16 to decorate by lining a cabin in the tubular seal part 10 of the seal piece 2a. On the other hand, a groove 20 which is installed in the seal part 10 of the seal 2a forms a core 10a in the seal part 10 of the seal piece 2b. The core 10a functions as an elastic resistance in the case the seal part 10 is deformed with elasticity. The elastic resistance of the seal part 10 is decreased by installing a shallow groove 22 in the seal part 10, and by adjusting the depth of the groove 22 the seal part 10 can be deformed with elasticity for the highest sealing property.

Title: Direct current circuit breaker
Inventor: YAMAMOTO HIROO
IPC: B60M3/04
Filed: 1980-02-19
Abstract: PURPOSE:To make compact the device and to reduce the cost, by sealing the main thyristor flowing the main circuit current and its accessory in a common enclosed vessel together with coolant. CONSTITUTION:When the rectifier at the power supply side supplies the rated capacity to the load, the rated capcity of the main thyristor 1 on each line is specified for one feeder and it must be in coincidence with the capacity. But, the total of 4 feeding lines is in coincidence with the rated capacity of the power supply side rectifier. Thus, the total loss of the main thyristor 1 for 4 feeding lines is almost the same as that at rated load reception for one feeder. Then, the main thyristors 1 and the accessories for 4 feeders' share can be cooled at a bundle with evaporation cooling of inactive material in a closed vessel 12.

Title: Dc power supply system
Inventor: SHIMIZU YASUHIRO
IPC: H02J1/00
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To prevent shunt current of another system from running through a chassis after a circuit breaker is tuned off if a short circuit occurs in a chassis, by making a Zener diode connection between the output return of a power supply system and the chassis. SOLUTION: The output return of a power supply system 1 is connected with a chassis by means of a Zener diode 8. If a short circuit occurs in a chassis, an internal breaker 4n in a switching device 2n on the upstream side of a failure position B detects overcurrent, so that it turns off automatically, and a part of current 1a to 1n-n of a normal system passes through the flywheel diode 5n in the failed system and returns to a point A via the Zener diode 8 from the chassis. As a result, the flywheel diode 5n is not actually turned on because a cathode potential exceeds an anode potential. It is thus possible to prevent current from running through the chassis after the breaker 4 is turned off even if a short circuit occurs in the chassis.
