Title: Motor with dynamic pressure bearing
Inventor: ICHIYAMA YOSHIKAZU
IPC: H02K7/08
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To obtain a proper bearing rigidity in a working temperature range stably by greatly reducing the temperature dependency of the bearing rigidity of a dynamic pressure bearing. SOLUTION: On the stationary side out of a shaft member 6 and a rotating sleeve substance 14, a connecting passage 46 which connects respective intermediate parts between the central parts and both end parts of dynamic pressure generating grooves 42, 44 made up of herringbonelike grooves and a low dynamic pressure part is provided, and in this connecting passage 46 a control valve 58 having an opening whose area becomes small at a high-temperature time, and becomes large at a low-temperture time is arranged.

Title: Light emanating diode
Inventor: NISHIZAWA JIYUNICHI
IPC: H01L21/205
Filed: 1979-11-16
Abstract: PURPOSE: To pick up a great quantity of light from a one surface disregarding a critical angle with a comparatively low price by a method wherein a light diffusion film is formed on the surface of a mono crystal semiconductor from which light is picked up.  
     CONSTITUTION: On the output surface of a GaAlAs LED consisting of an N type semiconductor 4, a P type semiconductor 5 and a P type crystal substrate 6, a polycrystal GaP 10 is precipitated in a several times thickness of a wave length. In other words, when a luminous wave length is 6,700Å and a refractive index of GaP is 3.4, approximately 1∼2μ film is precipitated because the wave length within the film is 2,000Å. Here, the grain diameter of the precipitation film must be rough and the precipitated film must not be transparent but must be a white milky light diffusion layer. With a light diffusion film like this, light reaching the surface enters the diffusion film and acatters to every direction, as a result, approximately 50% thereof can be picked up to the external side. Namely, in comparison with the case of using no diffusion film, light of 5 times or more is obtained, thus, resulting in a very light LED. Still, even if there exsists a film having a different refractive index as an inactivated film on a semiconductor surface, when a film thickness is sufficiently thinner than a wave length, a sufficient effect can be obtained.

Title: Manufacture of printing head for dot printer
Inventor: HIKI TOSHIO
IPC: B41J2/25
Filed: 1985-07-05
Abstract: PURPOSE:To make the simple manufacture of the printing head of which the breakage or the like are difficult to generate, by a method wherein the top of a printing pin is caulked by setting caulking jigs upward and downward, machined to a specific diameter by mechanical working and finished to an arbitrary shape. CONSTITUTION:The printing pin 20 is caulked by pressing it with an upper caulking jig 30 in a state in which the printing pin 20 is inserted into a hole 24 after setting the caulking jigs 30 having a circular shape less than the radius of the top of the member for projection 22, upward and downward and is jointed to the member for projection 22 to be fixed. Then, to make the top of the printing pin 20 be of a required diameter of approximate 0.2mm, the top of the printing pin 20 and the top of the member for projection 22 are mechanically ground and finished to arbitrary shapes. Because the diameter of the printing pin 20 to be inserted into the hole 24 is larger than the diameter of its top, the jointing strength becomes larger. Further, because caulked with the caulking jig 30 of small diameter, the printing pin 20 is jointed to the member for projection 22 over all its circumference and the jointing strength becomes larger. As the result, there is nothing to be afraid of slipping out of the printing pin 20.

Title: Power generator and electric washing machine equipped with power generator
Inventor: MOROZUMI HIDEKI
IPC: H02P23/04
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To operate a power generator surely without causing erroneous on/off operation of a switching element by providing an interruption signal generator for generating an interruption signal when the signal from a position detecting means is changed. SOLUTION: An interruption signal generator generates an interruption signal when any one of output signals from the Hall ICs 11, 12, 13 in a position detecting means is changed. Since the signal from the IC Hall is changed only when an interruption signal is generated, switching elements are not turned on/off erroneously and a power generator can be operated surely. Since a controller 10 is required to read out the signal from the IC Hall only when an interruption signal is inputted, other processing, e.g. speed control, can be performed easily when the interruption signal is not inputted if a microcomputer is employed as the control means 10 and stabilized feedback can be realized.
