Filed: 1993-09-29
Abstract: PURPOSE:To realize high accuracy and down-sizing by constructing a light projection means in a manner that an emitted light flux is condensed near a grid for modulation in the direction of a grid line and made parallel to the array direction of the grid. CONSTITUTION:A light flux is divided by a first diffraction grid G1 to obtain an interference light flux, and two light fluxes among the separated light fluxes are synthesized by a third diffraction grid G3. In such a process, each of optical path lengths separated between the grid G2 and grid G3 are designated by L1 and L2. A light projection means 100 is constructed in a manner that, in the direction of the grid line of the grid G1 or grid G3, a light flux is condensed along the respective light fluxes divided by the grid G1 at an area corresponding to the position of (L1+L2)/2 in optical path length and made substantially parallel to the grid array direction. Thus, an encoder insensitive to fitting accuracy can be constructed.

Abstract: PURPOSE:To improve the reliability for an adhesive part without after treatment, and also realize inexpensiveness and high reliability, by composing no printed part on a resist surface on a base plate in a part where a spacer and the base plate adhere. CONSTITUTION:Irregularity on an adhesive layer 4 between a contact sheet 3 or a spacer 5 and a base plate 1 surface, in particular on the base plate 1 surface in the outer peripheral part of the base plate 1, is lessened to the utmost. That is, printed parts 6 on resist layers 8 and 9 or circuit parts under the layers 8 and 9 are all constituted on an inner side than the adhesive part of the outer peripheral part of the base plate 1. Consequently, irregularity in an adhesive interface is only the smoothness of the surfaces of the layers 8 and 9, and an adhesive surface, having no gap or bubble, can be easily provided. Consequently, adhering, having no gap or bubble, is made possible, without using a thick-coated adhesive layer or nonwoven fabric impregnation type pressure sensitive adhesive, to easily realize concurrently a water intrusion preventive property and a steam permeability preventive property. Also the reliability of an adhesive part can be increased without after treatment such as end part sealing structure, and also inexpensiveness and high reliability can be realized.

Title: Organic electrolyte secondary battery
Inventor: KITA FUSAJI
IPC: H01M10/0568
Filed: 1988-10-24
Abstract: PURPOSE:To preclude hazard of firing from a battery when it is overcharged, by adding halides to electrolyte or into a positive electrode. CONSTITUTION:At least one sort of halide selected among halides of alkali metal, alkali earth metal, tetraalkylammonium, and alkyl is added to electrolyte or into a pos. electrode in an amount of 0.002-0.2mol/l. As this halide is reproduced in neg. electrode even after consumed in the pos. electrode, continued safety can be maintained. Added halide of the same metal as the neg. electrode is favorable because it does not react with the neg. electrode-e.g., LiCl, LiBr, etc., shall be preferred because of its large dissolusiveness in electrolyte. Thus hazard of firing even in the event of overcharging is precluded to accomplish a secondary battery with high safety.

Filed: 1990-10-05
Abstract: PURPOSE:To reduce a power loss in a snubber circuit by providing a second capacitor, connected in parallel to a diode through a second switch, and a second control circuit partly in an off-period of a first switch. CONSTITUTION:When an on-control given to an FET4a from a control circuit 14, disappears, the FET4a is converted to an off-condition. At this time surge voltage, which tends to be generated based on a primary winding 3, is absorbed based on first and second capacitors 18, 21. Thereafter, partly at least energy of the capacitors 18, 21 is transferred to the primary winding 3 in an on-period of an FET20a of a second switch 20 by resonance action based a closed circuit comprising the first and second capacitors 18, 21 and leakage inductance of the primary winding 3, and this energy is fed to a power supply by a circuit consisting of the primary winding 3, power supply 1 and a diode 4b of a first switch 4.

Title: Hardening refractory material
Inventor: HARORUDO ERU RIHITAA
IPC: C04B35/00
Filed: 1988-10-24
Abstract: Novel compositions are disclosed for the manufacture of gunning mixes and strong castable products for use as monolithic refractory and construction materials which may contain no lime bearing cements. Bonding is based on the setting reaction of fumed silica with an alkali metal silicate, preferably a particulate sodium or potassium silicate that slowly dissolves in water, such as an anhydrous sodium silicate having a SiO2:Na2O molar ratio of 3:1. Setting and mechanical characteristics allow this class of castable and gun mixes to be placed more rapidly into service since the time required for curing is much less. Although initial set strengths are nct as high as those of conventional castables, very high strengths can be made to occur shortly after setting by heating. The addition of sodium hexametaphosphate was found to be highly beneficial to working and handling characteristics.

Abstract: PURPOSE:To form thin films having good characteristics by combining plasma film formation and plasma etching as well as thermal film formation and annealing at the time of supplying a reaction gas to the surface of a work and forming the film thereon. CONSTITUTION:The pressure in a reaction chamber 3 is reduced and a magnetic field is formed above a wafer 2 by an electromagnet 17 at the time of filling deep grooves 40 of a wafer 2 by an insulating film with a CVD device 1. On the other hand, the microwaves mu are generated from a magnetron 6 and the reaction gas is supplied into the chamber 3 to form the plasma CVD film 41 on the inside wall of the grooves 40. The supply of the reaction gas is then stopped and an inert gas is supplied to the chamber. The wafer 2 is heated by the waves mu and the film 41 is annealed. The magnet 17 is then lowered and the power supply thereto is stopped. The vacuum degree in the chamber 3 is decreased to the value at which plasma reaction does not take place and the reaction gas is supplied to form the hot CVD film 42 on the film 41. The pressure in the chamber 3 is reduced when an overhung part 43 is generated. The magnet 17 is then risen to form the magnetic field and plasma etching is executed by supplying the reaction gas for etching; thereafter, the formation of the film 42 is started again.
