Title: Optical information detector
Inventor: TAKEMURA YASUHIRO
IPC: G02B7/28
Filed: 1986-05-02
Abstract: PURPOSE:To reduce the price and size of an optical system by using astigmatism included in light beams diffracted by a diffraction grating having <=2mu grating pitch to detect a converging point shear between a disk and an optical spot. CONSTITUTION:Light beams 22 radiated from a light source 21 are reflected by a reflection type diffraction grating 3 and converged on an information recording surface of the disk 26 through a collimeter lens 24 and an objective lens 25 and its reflected light beams are returned to the original optical path, receive, astigmatism by the diffraction grating 3 and arrive at a four-division type photodetector 29 to obtain a focus error signal. Since the diffraction grating 3 has the functions of a beam splitter, a cylindrical lens and full reflection mirror, the price and size of the optical system can be reduced.

Abstract: PURPOSE: To maintain fixed amount of oil supply by fitting caps of plural number at low end of revolving shaft, one over another, and by providing sump, between caps, to collect foreign articles which are separated by centrifugal force of revolving shaft.  
     CONSTITUTION: Low end of revolving shaft 3 is fitted with inner cap 7 and outer cap 8, each with oil passage opneing 7a, 8a, respectively, at their bottoms, and clearance between inner and outer caps makes sump for foreign articles. When revolving shaft 3 starts operation, oil 6 in tank 5 is centrifugrally rose through oiling opening 4 up to compressor. While operation, any foreign articles 11, entered through oil passage opening 8a, are scattered outward by centrifugal force and are caught at foreign article sump 9. Thus oiling opening 4 is prevented from chalking with foreign articles 11, to maintain amount of oil supply.

Title: Production of wheel made of aluminum or aluminum alloy for automobile
Inventor: YAMAGUCHI YOSHIHIRO
IPC: B60B3/04
Filed: 1979-08-11
Abstract: PURPOSE: To form a rim of uniform and smooth thickness by making a rim base through ironing of the cylindrical part of a blank material then roll forming the same thereby forming the rim.  
     CONSTITUTION: A wheel made of aluminum for automobiles is produced with good accuracy. For example, a mandrel 16 is fitted into the cylindrical part 10 of a cup- shaped member 9. While the mandrel 16 is rotated, an ironing roll 18 is contacted under pressure with the outside circumference of the cylindrical part 10 and the roll 18 is moved while it is ironing the cylindrical part 10, thereby forming a cylindrical part 10a. This is extremely uniform in thickness and the surface is smooth. Thence, a rim part is formed by a forming inside roll 3 and outside roll 4 or a traversing outside roll 14. The cylindrical part 10 is reduced in wall thickness to permit easy forming, thus the extremely uniform rim part is formed. It is also possible to draw and iron the cup-shaped member from a plate material or to iron a cylindrical member of an H shape in section.

Title: Underground proving radar
Inventor: NAKAYAMA NOBORU
IPC: G01S13/88
Filed: 1993-04-28
Abstract: PURPOSE:To prevent an amplifying circuit from being saturated by the excessive reflected waves reflected on the ground surface and made unable to properly amplify the succeeding weak reflected waves by an underground buried object. CONSTITUTION:The output from an antenna receiving the reflected waves is applied to a high-gain high-frequency amplifying circuit via a limiter 1. In the limiter 1, the voltage of the first and second power sources 15, 16 is divided by the first through fourth resistors R11, R21, R12, R22, the forward bias voltage is applied to the first and second diodes D1, D2, and the limiter limiting voltage is reduced. The first and second capacitors C1, C2 are charged by the voltage obtained when the excessive reflected waves by the ground surface are rectified by the first and second diodes D1, D2, the charging voltage reduces the forward bias voltage, and the weak reflected waves by an underground buried object are applied to the amplifying circuit without being attenuated while the S/N ratio is not reduced.

Title: Container cap and bottom hanger
Inventor: UEDA RYOZO
IPC: A61J1/16
Filed: 1995-04-05
Abstract: PURPOSE: To reduce possibilities of rupture at break lines on mold-releasing in injection molding, and to improve yield rate in manufacture by a method wherein grooves are provided at positions near the break lines for a container cap or a bottom hanger. CONSTITUTION: In a resin cap 1 or a bottom hanger in a short cylindrical shape that is provided with a projecting stripe 12 for fitting to a mounting/dismounting part of a container at the inside of a circumferential wall 8, and removable from the container with the circumferential wall 8 severed at break lines 9 in the form of V-shaped groove, grooves 13 and 14 are formed at positions near the break lines 9. On mold-releasing after resin is pressure-injected into a mold in injection molding, the part of the projecting stripe 12 is expanded when the projecting stripe 12 climbs over the mold. However, as distortion arising from expansion is absorbed by the grooves 13 and 14, reducing load working on the break lines 9, possibilities of rupture at the break lines can be reduced and yield rate can be improved in manufacture.

IPC: G02F1/155
Filed: 1991-03-25
Abstract: PURPOSE:To obtain the method for forming plated electrodes which can form the plated electrodes for an electrochromic element (EC element) with good positional accuracy. CONSTITUTION:After a masking material 3 is applied over the entire surface of a substrate 1, the substrate is subjected to ball lapping to a prescribed outer peripheral shape. The masking material 3 is applied again at the prescribed point in the outer peripheral part of the substrate subjected to the ball lapping and thereafter, the respective masking materials 3 are removed. After the masking material 3 is applied over the entire surface of the substrate 1, the prescribed outer peripheral shape is subjected to the ball lapping, by which the formation of the outer peripheral shape and the peeling of the masking material from the end face to be plated are simultaneously executed. The plated electrodes 4 for the EC element are thus formed with the good positional accuracy.
