Title: Planetary gear type speed decelerator
Inventor: KOTANI KUNIO
IPC: F16H1/28
Filed: 1984-07-24
Abstract: PURPOSE:To reduce both the size and the weight of a speed decelerator having a great ratio by housing a plurality of planetary gear decelerator units inside a case and enabling the units of being slided in the axial direction with respect to the case. CONSTITUTION:A decelerator unit 8c, which is a terminal unit, is provided with a ring gear 13 having a projection 8a on the external periphery thereof, three planetary gears 14, three planetary shaft 15, three pairs of planetary rollers 16, a set of planetary carriers 17 and 18 and a sun gear 19. Other decelerator units, which are a primary and a secondary ones, are constituted similarly. The teeth of the sun gear 19 is longer than the teeth of the planetary gears 14 and a serration 17B1 having the same number of teeth as that of teeth of said sun gear 19 is formed on a planetary carrier 17B of the former-stage decelerator unit. The decelerator units may therefore be joined with each other in a quick and easy manner inside a case 9.

IPC: G11B17/028
Filed: 1985-07-12
Abstract: PURPOSE:To efficiently remove a harmful oscillation during reproducing by attaching a rubber having a large internal oscillation attenuation factor to a material of large rigidity and providing a suitable rigidity and oscillation absorption effect. CONSTITUTION:A plate part 2 made of a disk like metal having a hole 1 at a center part and a ring like rubber plate 3 of large oscillation attenuation factor at its outer peripheral part and of a size to contact the hole of the compact disk and an intermediate part of an outermost diameter are welded. A compact disk 7 and a stabilizer are together presses to a turn table 6 by a clamper 8 to rotate and a pick up 10 optically reads a signal on a recording surface of the compact disk. In this manner, since the rubber surface 3 of the stabilizer tightly contacts a flat surface easily oscillating of the compact disk 7, the oscillation of the compact disk 7 by the rotation can be restricted by the stabilizer.

Title: Image filter circuit
Inventor: MURAKAMI HIROSHI
IPC: G06T5/40
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To miniaturize an image filter circuit by using an IIR type filter for a filter for blurred image possession and using an FIFO type field memory for a delay circuit for synthesizing an image signal not to be processed with a processed image signal. SOLUTION: A blurred image signal is generated by using the IIR filter for a FIL 76. Thus, the circuit for blurred image signal generation can be miniaturized. Besides, DLY 75a and 75b are delay circuits for delaying image signals, to which filtering processing is not performed by the FIL 76, for the delay time of image signals, to which filtering processing is performed by the FIL 76, and while parallelly providing two FIFO type field memories, images are alternately written and read two by two. Since this memory has no external address terminal, circuit configuration can be simplified and besides, since two memories are parallelly used, capacity can be increased and the delay time of image signal caused by the FIL 76 can be suitably dealt with.

Title: Preparation of potassium tetracyanoaurate (3)
Inventor: KONASE TAKASHI
IPC: C01C3/11
Filed: 1979-11-27
Abstract: PURPOSE: To obtain high-quality potassium tetracyanoaurate (III) in simple operation, by extracting a reaction product between an aqueous solution of gold (III) chloride and potassium cyanide with an organic solvent.  
     CONSTITUTION: Gold (III) chloride or purity 99% or higher is dissolved in pure water to give an aqueous solution of the gold chloride in a concentration of about 100W300g/l, and potassium cyanide is then added and reacted with the solution under agitation. The potassium cyanide preferably has as high a purity as possible (purity of 95% or higher). After the reaction, the solution is heated and concentrated until a film begins to form on the surface of the solution, and cooled to crystallize the reaction product, which is then filtered. The resultant reaction product is brought into contact with an organic solvent to extract potassium tetracyanoaurate (III) in the organic solvent. The extracted potassium tetracyanoaurate (III) is then separated from potassium chloride by the filtration or decantation.

Filed: 1989-06-15
Abstract: PURPOSE:To obtain an electrode plate for plasma etching characterized by high purity, high strength and long life by providing a glass-state carbon layer containing carbonized fiber at one side. CONSTITUTION:A glass-state carbon layer containing carbonized fiber on one side is provided. As the raw material for the carbonized fiber, the following materials are used: carbon fiber; hardened phenol fiber; cotton fiber; and fiber comprising polyvinyl alcohol. The manufacturing method of the fiber is as follows: e.g. the cotton fiber is inputted into the liquid of the initial condensate of furfuryl alcohol together with a hardening agent; a container is heated and turned with a centrifugal molding machine; and a semihardened cylindrical resin molded body is obtained. Then, the molded body is cut and expanded. The cut body ls compressed, heated and hardened. Thereafter, the material is baked and carbonized in an non-oxidizing atmosphere. Furthermore, graphitization and high purification are performed. Thus, the strength is increased, and the reinforcing surface becomes fine. Therefore, the collapsing phenomenon of organization due to the pull-out of particles does not occur. Etching which is stable for a long time can be carried out.

Abstract: PURPOSE:To obtain excellent correlative characteristics between switching characteristics and an ON-voltage by a method wherein high impurity concentration p-type and n-type regions are selectively diffused on the main surface of a semiconductor substrate and, after a buffer layer and an element region are successively formed, the rear of the substrate is polished to expose the high impurity concentration p-type and n-type regions on the opposite main surface. CONSTITUTION:High impurity concentration p-type regions 22 and high impurity concentration n-type regions 23 are selectively diffused on a p-type semiconductor substrate 21 having a thickness of 400mum so as to have a thickness about 50mum. Then an n<+>-type buffer layer 24 having a thickness of 15mum and an n<->-type layer 25 having a thickness of 105mum are successively formed on the p-type regions 22 and the n-type regions 23. At that time, a total thickness is about 520mum. Then an element region is formed in the surface region of the n<->-type layer 25. After that, the approximately 370mum thick part of the semiconductor substrate 21 is polished to expose the high impurity concentration p-type regions 22 and the high impurity concentration n-type regions 23 on the polished surface. If a collector electrode 34 is deposited on the polished surface, an anode-short type IGBT can be obtained. Even in a device having a breakdown strength of not higher than 2000V, the ideal impurity profile of the n<+>-type buffer layer can be maintained and characteristics can be improved.
