Title: Manufacture of dynamic pressure bearing
Inventor: YASUDA TAKAFUMI
IPC: F16C33/20
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent flawing of a recess/projection pattern of a cylindrical body by molding the cylindrical body composed of an abrasion resistant resin material on the outer periphery of a shaft forming a pair of herringbone-shaped patterns on the outer periphery, and removing the shaft from the cylindrical body by a forcibly extraction construction method. SOLUTION: A cylindrical body 3 composed of a PPS resin being an abrasion resistant resin material is injectively molded on the outer periphery of a shaft 1 forming a pair of herringbone-shaped patterns 2 on the outer periphery. Next, the shaft 1 is removed from the cylindrical body 3 by molding a herringbone-shaped recess/ projection pattern by resin on the inner periphery in a preprocess by a firceibly extracting construction method. At this time, since a groove 4 having the prescribed depth is formed in the central part sandwiched by a pair of patterns 2 of the shaft 1, forcibly extracting time deformation is absorbed, the forcibly extracting construction method can be easily performed without damaging a recess/projection pattern, and the cylindrical body 3 of a dynamic pressure bearing having a recess/projection pattern on the inner peripheral surface can be easily manufactured.  Therefore, Thus, mass productivity is increased, the dynamic pressure bearing can be inexpensively manufactured, abrasion between a shaft and a bearing can be reduced, and the service life can be prolonged.

Abstract: PURPOSE:To surely prevent the light leakage from a sealing material without adversely affecting the printability of a sealing material and the orientation of a liquid crystal by adding a specific amt. of carbon powder into the sealing material and adding a specific amt. of black spacers thereto. CONSTITUTION:An epoxy resin 6 as a thermosetting resin added with the carbon powder 7 and the black spacers 8 is used as the sealing material 3 which is provided between an upper electrode substrate 1 and a lower electrode substrate 2 of the liquid crystal display element and is used to adhere these electrode substrates 1, 2. The carbon powder 7 is added at 0.5 to 1.0wt.% to this sealing material and the black spacers having the grain size slightly smaller than the gap between the two electrode substrate s l, 2 is added at 5 to 10wt.% thereto. The black spacers 5 are formed by coating the surfaces of spherical divinyl benzene resins 8a with a coloring material 8b. The light transparency of the sealing material 3 is drastically lowered in this way without impairing the printability.

Title: Luminous flux deflector
Inventor: WADA HIROYUKI
IPC: G03B5/00
Filed: 1994-06-01
Abstract: PURPOSE:To decrease the number of parts without requiring supporting means of movable optical members by providing connecting members for connecting the movable optical members and stationary members with such rigidity to prevent the connecting members from being deformed by the weights of the movable optical members, transparent materials and connecting members. CONSTITUTION:A variable vertex prism is constituted by filling liquid having a high refractive index into the space hermetically sealed by two sheets of transparent plates 21a, 21b and four sheets of films 22a to 22d for sealing the outer peripheries. These films 22a to 22d are welded by joint parts 22e, 22f, 22g. Since the joint parts 22e to 22g are formed to a circumferential shape, the degree of freedom in the radial direction of the transparent plates 21a, 21b is lost. The transparent plates 21a, 21b enable spherical movement around the center of the variable vertex prism but enhance the rigidity of the films 22a to 22d against the weights of the liquid in the variable vertex prism and the moving parts and, therefore, the supporting members for the films are no longer needed by this constitution.

Abstract: PROBLEM TO BE SOLVED: To make a magnet not dropped off even if a bending stress acts on a driving shaft by embedding this magnet, constituting a rear wheel steering angle sensor, into an outer surface of the driving shaft, and supporting the magnet with a heat contraction tube inserted into this driving shaft. SOLUTION: A magnet 11 constituting a rear wheel steering angle sensor is embedded into a driving shaft 6 so as to make it flush with a peripheral surface of this driving shaft 6. In a state of keeping this magnet 11 embedded intact, a heat contraction tube 15 is inserted in and around the magnet, and this tube 15 is heated into contraction, making this tube 15 stick fast around the driving shaft 6. In consequence, the magnet 11 is held tight to the driving shaft 11, therefore even if a bending stress from the outside acts on the driving shaft 6, this magnet will in no case separate from the driving shaft 6. It is recommended that this tube 15 is composed of such a material as being transparent, through which whether the magnet 11 is held in a position aright or not is made easily sightable.

Title: Light semiconductor device
Inventor: YOSHIKAWA TOSHIBUMI
IPC: H01L31/00
Filed: 1978-09-28
Abstract: PURPOSE: To improve the spectral sensitivity characteristics of a light semiconductor device with respect to light of desired waveliength area without filter.  
     CONSTITUTION: PN junctions 2 and 3 are provided in different depth from the surface of a substrate to thereby form photodiodes PD 1 , PD 2  connected inversely. The photodiode PD 1  is located deeply to sense the long wavelength component of light, while the photodiode PD 2  senses the short wavelength component. Accordingly, the short wavelength component is absorbed in the area near the surface, and converted to current by the photodiode PD 2 , while the long wavelength component is protruded into deep portion of the substrate, and converted to current by the photodiode PD 1  to thus produce light output current responsive to the illuminated light from electrodes 4∼6. When the electrodes 4, 5 are shorted by an aluminum wire or resistor to thereby consume the output of the photodiode PD 1 , the spectral sensitivity characteristics of the semiconductor device is remarkably decreased at the long wavelength side to thereby provide characteristics having a sharp peak in visible area. when the electrodes 5 and 6 are similarly shorted, the short wavelength side sensitivity is lowered to provide characteristics having a sharp peak in infrared ray area.
