Title: Spherical or cylindrical magnet
Inventor: SHIMIZU MICHITOSHI
IPC: B03C1/00
Filed: 1987-05-27
Abstract: PURPOSE:To adjust the magnetic density and the specific gravity by a method wherein a shell of a magnetic oxide is formed at an external circumference of a spherical or cylindrical magnet, its inside is shaped to be hollow or is filled with a foaming polystyrol resin and a resin-coated layer is formed at the external circumference of the shell. CONSTITUTION:An external circumference of a small spherical or cylindrical magnet is formed by using a magnetic oxide; its inside is formed as a hollow part 2 or is filled with a foaming polystyrol resin 4. As necessity requires, a resin-coated layer 3 is formed at the external circumference of a layer 1. As the magnetic oxide, an Mn-Zn-related ferrite, an Ni-Zn-related ferrite, a rare-earth metal Fe-related ferrite or the like is used. If this magnetic oxide is heated and sintered, the magnetic density can be enhanced; the specific gravity can be made to be more than one in such a way that a liquid can penetrate into the hollow part 2 through the shell composed of a porous material having fine vacant spaces; on the other hand, the specific gravity can be made less than that whose external circumference of the shell is coated with the resin in order to prevent the liquid from penetrating or that the inside is filled with the foaming polystyrol resin.

Title: Cylinder device for balance
Inventor: IGA TAKUMI
IPC: B25J19/00
Filed: 1989-05-23
Abstract: PURPOSE:To prevent the increase of the starting resistance and sliding resistance by a sealing member independently of the increase of the supplied pressure by forming a fluid passage for applying the reverse pressure which is equal to the balance pressure onto the opposite surface to the surface onto which the balance pressure of a sealing member which is installed onto the outer wall of a piston is applied. CONSTITUTION:The balancing air operates a pressurizing force onto the side surface of a piston 2, and operates a pressurizing force also onto an oil seal 4a. Therefore, the oil seal 4a is formed so as to increase the contact area with the inner wall of a cylinder 1. Further, if a seal bulging-out preventing air which is balanced with a pressurizing force F due to the balance air is supplied through a fluid passage 7, the equal pressurizing force F acts onto the opposite surface of the oil seal 4a, and a component force F2 for offsetting the component force F1 acts. Therefore, the deformation of the oil seal 4a is surely suppressed, and the starting resistance between the inner wall of the cylinder 1 can be kept at a small value.

IPC: G01B11/00
Filed: 1995-05-01
Abstract: PURPOSE: To obtain an apparatus for measuring the eccentricity by which the eccentricity of every face of a lens system constituted of many optical elements can be measured easily and with high accuracy by a method wherein eccentricity information on a face to be measured is obtained by a signal from a photodetector. CONSTITUTION: A luminous flux 2 is divided into luminous fluxes 2a, 2b by a semitransparent mirror 5 inside an intereference optical system 4, and the two luminous fluxes are changed into luminous fluxes which are parallel to the optical axis of a focal length-variable lens 9 so as to be incident on the lens 9. Then, the luminous fluxes 2a, 2b which are reflected by a face 16 to be measured regress partly in a route up to this time and returns to the mirror 5. Interference light by the luminous fluxes 2a, 2b which are overlapped by the mirror 5 is received by a photodetector 10, and its output signal is amplified by an amplifier 29. The output signal of the amplifier 29 is adjusted finely by the lens 9 in such a way that the beat amplitude of the interference light becomes maximum.  Then, a point in which the luminous fluxes 2a, 2b are condensed and cross, can be made to agree nearly completely with the center of the curvature of the face 16 to be measured when the phase of the beat of the interference light is measured, the amount and the azimuth of the eccentricity of the face 16 to be measured are found.

Title: Angular velocity sensor
Inventor: NOZOE TOSHIYUKI
IPC: G01C19/5614
Filed: 1995-05-30
Abstract: PURPOSE: To detect a failure of sensor and to enhance reliability of a monitor by a constitution wherein a mechanical connection signal except an angular velocity output obtained from a detection body is designated as a monitor signal. CONSTITUTION: It is hard to make sizes of piezoelectric elements 13a, 14a and the ways of attaching the same, and as the result, mechanical connection signals are always generated from the elements 13a, 14a. The elements 13a, 14a are attached to the identical sides of detection plates 13, 14 respectively, and since centroids of the plates 13, 14 are slightly shifted to the sides where the elements 13a, 14a are attached, when drive plates 11, 12 vibrate as a tuning fork, they are bent toward the sides of elements 13a, 14a to be widened. Therefore, since mechanical connection signals generated on the elements 13a, 14a have the phases reversed to each other, the mechanical connection signals at a D point are synthesized to be suppressed.  The synthesized mechanical connection signal is amplified by a change amplifier 20 and an amplifier 25, rectified by a rectifier 26 and smoothed by a smoother 27, then the level thereof is judged by a judgment device 28. The judgment result is outputted from a monitor signal terminal 29.

IPC: H01L23/28
Filed: 1988-05-31
Abstract: PURPOSE:To reduce the leak of light from a light emitting segment to a segment which does not emit light by forming a metal skin only on a frame pattern corresponding with the rear opening part of a reflector, and making the other part black and brown by heat-treating. CONSTITUTION:A metal skin 11a is formed on a pattern facing the rear transmitting hole part of a reflector 105, and a coating film 11b colored so as to absorb light is formed on the pattern of the other part containing the rear. Coloring is done by heating the frame and forming, e.g., a black oxide layer on a surface layer, or by forming a coating film of application. The leak of light from a gap between the rear transmitting hole part of the reflector 105 and the frame pattern is absorbed by the oxide layer of light absorption color or the coating film 11b. Thereby, the leak of light from a light emitting segment to a segment which does not emit light is reduced.
