Title: Optical device for infrared ray
Inventor: SAKUTA HIRONOBU
IPC: G02B13/22
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of the incidence of unnecessary infrared rays on an image by making the exit pupil of a composite optical system of an object optical system and an image re-forming optical system meet the cold aperture of a sensor means for infrared rays. SOLUTION: The objective optical system 1 is an optical system which is telecentric (having its exit pupil at the infinite distance) to an image side. The imaging optical system 5, on the other hand, is telecentric (having its entrance and exit pupils at the infinite distance) to an object side and its exit pupil meets the position of the cold aperture 8. Then the objective optical system 1 and imaging optical system 5 are connected while being made eccentric with each other so that the center of a linear image (intermediate image 4) inscribed in a ring field formed by the objective optical system 1 is aligned with the optical axis of the imaging optical system 5.  Thus, the exit pupil of the composite optical system of the objective optical system 1 and imaging optical system 5 meets the position of the cold aperture 8 and the composite optical system is what is called an aperture matching type optical system.

Title: Optical disk device
Inventor: SAITO YOSHIHARU
IPC: G11B7/085
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To rapidly and surely perform a seek. SOLUTION: For instance, when the instruction of the seek is imparted to a microcomputer 24, the microcomputer 24 turns a switch SW1 off. Then, a tracking servo circuit 10a is turned off intentionally at a seek time. Further, when an optical pickup 12 is moved in the thread direction while seeking, a servo gain of a feed servo circuit 10b is set smaller than the time at a read time in a second signal processing circuit 32 according to the instruction from the microcomputer 24. Thus, even when an objective lens 12 is oscillated just after the optical pickup 12 is moved at high speed, the feed servo circuit 10b isn't operated corresponding to this oscillation. That is, the optical pickup 12 doesn't cause chattering. Then, when the optical pickup 12 arrives at a target position, the servo gain is returned to the origin, and the switch SW1 is turned on, and the read is executed.

Abstract: PROBLEM TO BE SOLVED: To reduce a size and cost by stirring the surface of liquid stored in a heating evaporator. SOLUTION: The upper one end of a shaft 46 freely rotatably held by the heating evaporator 10 is provided with a gear 45 which reduces the speed of the revolution of a motor 41 via a gear 44 disposed at the shaft 42 of the motor 41. The revolutions thereof are transmitted to the shaft 46 of rotary stirring vanes 47 having a symmetrical rectangular shape. The shaft 46 is freely rotatably held perpendicularly by the heating evaporator 10 and the rotary stirring vanes 47 stir the surface of the liquid 11, thereby preventing the gas- liquid boundary from being covered with suspended matter and improving evaporation efficiency. The rotary stirring vanes 47 sufficiently stir the liquid 11 near a base without coming into contact with the horizontal base of the heating evaporator 10.  Even if the liquid 11 stored in the heating evaporator 10 is concentrated to make heat transfer difficult, the liquid 11 existing on the heating surface from heating members is stirred and, therefore, scorching is suppressed. A good heating efficiency is obtd. and the heating evaporator 10 is made small in size and inexpensive.

Abstract: PROBLEM TO BE SOLVED: To store an electrode set in a container without damaging the electrode set, to improve the reliability, to elongate the life, and to provide high storage capacity by using a separator formed into a specific thickness by pressurizing a sheet which contains polyolefine fiber and has a specific mass weight. SOLUTION: A sheet of nonwoven fabric which contains polyolefine fiber made hydrophilic by graft copolymerization of vinyl monomer and has a mass weight of 40-60 g/m<2> is heated and pressurized so as to be formed into a separator 3 of thickness 0.09-0.11 mm, and a positive electrode 2 and a negative electrode 4 are wound around by intervening the separator 3 so as to form an electrode set 5. This constitution can secure a space in the container, while preventing the internal short circuit of the separator 3, so as to prevent the leakage caused by gas generation. The electrode set 5 is suppressed from being bulky caused by the inclination to the high storage capacity so that the negative electrode is prevented from being scraped by the container 1 in storing the electrode set 5 in the container 1.  The separator is pressurized at 120 deg.C or more and at below the melting point of the polyolefine fiber.

Abstract: PURPOSE:To produce a p-type layer and an n-type layer using one dopant, and to produce an insulating layer with superior insulating characteristics by alternately superimposing InAs and GaAs with a superlattice structure, and by adding C as impurities to the GaAs layer. CONSTITUTION:The principal part of a semiconductor device is composed of a semi-insulating substrate 1 made of InP, a buffer layer 2, a p-type InGaAs superlattice structure A, and an n-type InGaAs superlattice structure B. The p-type InGaAs layer is formed with a multilayered superlattice structure which is made up of alternately superimposed layers of InAs and GaAs. C is added as impurities to a p-type GaAs layer when it is layered, and InAs and GaAs are alternately overlaid with a superlattice structure when the n-type InGaAs layer is formed. Thereby, the GaAs layer positively becomes a p-type, and the multilayered InAs and GaAs layer becomes a p-type InGaAs, and hence an insulating layer with superior insulating characteristics can be produced.
