Title: Laminated ceramic capacitor
Inventor: SAITO SUSUMU
IPC: H01G4/12
Filed: 1987-10-21
Abstract: PURPOSE:To obtain a capacitor of high dielectric constant having a small temperature coefficient and excellent electric characteristics by a method wherein a ceramic layer of specific thickness is interposed between high permeability materials using a plurality of high dielectric constant materials having different Curie points. CONSTITUTION:On a laminated ceramic capacitor, ceramic dielectric layers having different Curie points are formed at least using two kinds of porcelain composition materials, and a porcelain composition material of 3-30mum and a ceramic layer, which is hardly formed into a solid solution, are formed between a plurality of ceramic dielectric layers. The diffuse reaction generating in a sintering process can be prevented by interposing a ceramic layer of 3-10mum between the porcelain composition materials having different Curie points. As a result, the capacitor can be brought into a composite without changing the Curie point of each material, and by combiningly laminating the material having optical Curie point, the capacitor having a high permeability and a small temperature coefficient of capacitance with temperature can be accomplished.

Title: Optical coupler and mutually connectable star coupler
Inventor: OTA TAKESHI
IPC: H04B10/272
Filed: 1993-10-26
Abstract: PURPOSE:To obtain an optical coupler of a single mode without any confluent loss by serially connecting a Y-shaped branching path with an evanescent optical coupler. CONSTITUTION:The optical coupler shown by a figure is the optical coupler in which the asymmetrical Y-shaped branched path is in series connected with an evanescent optical coupler 4. On a boundary surface between a connecting part 3 and the evanescent optical coupler 4, an optical path difference is adjusted so that the phases of two optical waveguide are in phase that is, a phase matching condition is satisfied. In a single mode optical waveguide, a light is made incident from one optical waveguide 5b of a branching part 4, and in the evanescent optical coupler 4, the light of an optical waveguide 4b is mode-connected on an optical waveguide 4a side and branched, and the branched lights are made confluent again at the asymmetrical Y-shaped branched path 2. At that time, when the phases of the two branched lights are opposite, they are cancelled and the loss is generated. In this case, the optical difference is adjusted so that the phase matching condition can be satisfied and the loss can not be generated. This is applicable to the light made incident from the other optical waveguide 5a of the branching part 5.

Title: Duct switching device for endoscope
Inventor: OGINO TAKAYUKI
IPC: A61B1/00
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of lubricant application to a sealing member every time when a piton is mounted on a cylinder by mounting an O-ring for lubrication impregnated with a lubricant on the periphery of the piston so that the sealing member may contact the inside periphery of the cylinder by the advance and withdrawal of the piston. SOLUTION: When the piston 34 is pushed into the cylinder 31 by pushing an operating button 36 with a finger, an opening 44b on the periphery of the cylinder faces the opening of a suction pipe 4, and two suction pipes 4 and 5 are connected through a communicating hole 44, enabling suction from an opening at the tip. At this time, the circumference of the opening 44a of the end of the communicating hole 44 is sealed with an O-ring 48, and the circumference of the opening 44b of the periphery of the piston is sealed with a sealing member 50. Therefore, suction of atmospheric air into the suction pipe 4 from the circumference of the piston 34 does not occur. Since a sealing O-ring 8 is impregnated with silicon oil, and the silicon oil is supplied to the sealing member 50 from the lubricating O-ring 60, there is no need for application of a lubricant every time when they are assembled.
