Title: Push-button switch
Inventor: NAKASE TAKEAKI
IPC: H01H13/20
Filed: 1987-05-18
Abstract: PURPOSE:To make the operational feeling excellent, to decrease the difference between the action force and the restoration force of an operating body, and to reduce the absolute value of the action force, by using two links pivoted and incorporated preliminarily to eliminate the sliding friction resistance remaining only a rotation friction resistance. CONSTITUTION:Two links 17 and 18 which are pivoted and incorporated preliminarily are set, and operated by depressing an operating body 15. The links 17 and 18 are rotated around a supporting point 17a and a supporting axis 18a. Since the supporting axis 18a is held by a receiver 11a of a case 11, a sliding body 13 is moved to the left. When the operating body 15 is depressed further, the whole members are in the moving condition, and the switching of contact is completed. When the depressing of the operating body 15 is stopped in such a condition, the operating body 15 is restored to the original position by the reaction of a coil spring 19. By such constitution, the assembling of the two links can be simplified, the operational feeling is made excellent, and the difference between the action force and the restoration force of the operating body, and the absolute value of the action force can be reduced.

Abstract: PURPOSE:To obtain a laminated sheet excellent in heat resistance, dimensional stability and electricl properties, by laminating a plurality of sheet bases coated with a mixture of a resin composition comprising a specified (co)polymer and a crosslinking agent and curing the asemblage under an applied pressure. CONSTITUTION:An impregnation varnish is obtained by dissolving a resin composition comprising a (co)polymer (A) containing at least 50% structural units in the polymer chain in a solvent (e.g., hexane) to form a solution of a concentration of 10-50wt% and adding 0.1-20pts.wt., per pt.wt. component A, crosslinking agent (B) (e.g., benzoyl peroxide) to the solution. Sheet bases (e.g., glass cloth) are impregnated with this varnish and dried at room temperature to 170 deg.C to obtain nonsticky prepregs. A necessary number of the prepregs are laminated, cured and bonded by heating to 50-350 deg.C under a pressure of 1-100kgf/cm<2>.

Title: Vapor phase growing method for gallium nitride
Inventor: YONEDA KIYOSHI
IPC: C30B25/14
Filed: 1979-09-18
Abstract: PURPOSE: To obtain a flat GaN layer on the surface of a GaN epitaxial layer without causing the abnormal growth of GaN by feeding NH 3  gas and carrier gas toward a Ga source in a direction contrary to that in crystal growth after finishing the crystal growth.  
     CONSTITUTION: NH 3  gas and carrier gas are fed from inflow pipe 11, and HCl gas and carrier gas from inflow pipe 15. Ga and HCl react, and GaCl formed flows into reaction tube 10, where it is converted into GaN by reaction with NH 3 . The resulting HCl and H 2 , unreacted NH 3  and the carrier gas are exhausted from outflow  pipe 21. Valves 13, 16, 23 are open during the epitaxial growth, after the growth  the valves are closed, and valves 14, 24 are opened to introduce NH 3  gas and carrier gas from inflow pipe 22 in a flow contrary to the former flow. By carrying out  slow cooling, the reaction of HCl accumulated in pipe 15 and Ga does not take  place to prevent GaCl from spouting from the nozzle tip. Thus, the abnormal  growth of GaN is not caused on the surface of a GaN epitaxial layer to give a flat  GaN epitaxial layer.

IPC: G10L15/08
Filed: 1990-05-09
Abstract: PURPOSE:To improve the word recognition rate by using a neural network for all registered words to be learnt and neural networks for respective groups of similar registered words to be learnt. CONSTITUTION:The neural network (NN part) 13 for all the registered words to be learnt and the group NN parts 4 for the respective groups of all the registered words grouped according to the state wherein output values of respective output units constituting the above NN have constant similar relation and threshold decision making is impossible are used and an input word is recognized by the NN part 13.

Abstract: PURPOSE:To treat electrolytically the surface of a wire at a high sped with high efficiency by providing turn rolls at both ends of a treatment tank, running the wire to be treated across the rolls so as to intersect with each other and energizing the wire with the turn rolls to treat electrolytically the wire surface. CONSTITUTION:The wire (a) to be treated is run across the turn rolls 1, 1' in common use as power feeders so as to intersect with each other in the stage of subjecting the metallic wire surface to electroplating, electrolytic degreasing or electrolytic polishing. The wire is then passed through the inside of the treating liquid tank 2 for plating liquid, etc. in which an anode 3 is disposed. The treating liquid such as plating liquid is stirred by the traveling wire (a) according to the above-mentioned method. The current density of the traveling wire in the treating liquid is thereby easily increased and since the wire passes repeatedly through the inside of the treating liquid, the thick plating layer is easily formed. The treatment with high efficiency is made possible even in the electrolytic degreasing and electrolytic polishing.

Abstract: PURPOSE:To obtain a picture coder showing excellent performance under a high compression rate by picking up a texture of a picture so as to add information related to the texture to a code. CONSTITUTION:Data are segmented into blocks of a predetermined size by a block segmentation means 102 and the block is fed to a DCT transformation section 103, in which the block is transformed into a frequency region. An inverse DCT transformation section 104 generates a reproduced picture from a DCT coefficient for a low frequency within a prescribed range after the quantization. A texture characteristic extract section 105 extracts two fractal characteristic quantities based on the difference between the reproduced picture obtained by the transformation section 104 and the original picture. An output of the transformation section 103 and an output of the extract section 105 are converted into a code by a quantization coding section 106 and the operation of the coding section 106 is controlled by the operation of a fractal characteristic discrimination section. That is, to which of a DCT coefficient obtained from the transformation section 104 or the characteristic quantity obtained from the extract section 105 is used for emphasis for the coding is discriminated.
