Title: Photoswitch
Inventor: NISHIWAKI YOSHIKAZU
IPC: G02B26/08
Filed: 1979-07-03
Abstract: PURPOSE:To obtain a photoswitch of simple and rigid construction by branching only the specific one wavelength of the wavelength multiplex signal, and letting this light be shielded or transmitted. CONSTITUTION:An optical fiber 1 for transmission transmitting the wavelength multiple photo signal is interposed with a branching filter 2 and a wave combining device 3. The branching filter 2 takes out the light of the specific wavelength and transmits the light of other wavelengths, and the wave combining device 3 has the function of combining the light of the branched wavelength with the light of the other wavelengths. The light of the specific wavelength emitted from the 1st optical fiber 4 connected to the branching filter 2 is led into the 2nd optical fiber 5 connecting to the wave combining device 3. Hence, it is possible to know the condition of a light shielding plate 6 by detecting the presence or absence of the light of the specific wavelength in the light having been transmitted in the optical fiber 1. In this way, the photoswitch of the simple and rigid construction is obtained.

Title: Automatic welding method
Inventor: HOSHINO KIYOTAKA
IPC: B23K9/12
Filed: 1979-07-03
Abstract: PURPOSE: To eliminate variance in welding time and prevent the use of welding defectives by ceasing the generation of an arc and shifting into the next process when no arc is generated within the predetermined time since the welding process is started.  
     CONSTITUTION: When a mold 6 and a plasma torch 1 descend, limit switches 14, 15 close and the contact 17 of a timer closes as well. Hence, electric current flows from a current transformer 19 to the circuit of the timer 18 via an ammeter 20, causing the timer 18 to start actuating. When the ammeter 20 indicates that the electric current sufficient for welding has flowed in the specified time, the contact 23 closes and holds himself. Hence, even if the contacts 18A, 18B of the timer open after the predetermined time, a welding electric power source circuit 16 is held closed and welding is accomplished. However, if the rise of the electric current does not reach the predetermined current value within the predetermined time, the contacts 18A, 18B of the timer 18 open and a relay 21 stops actuating; the welding electric power source circuit 16 opens; no welding is done and the process is shifted to the next process.

Title: Conductive paste and electronic part

IPC: H01B1/22
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To provide paste for preventing the occurrence of a crack and delamination by covering the surface of a base metal particle with nickel oxide. SOLUTION: Desirably in conductive paste, a base metal particle is a nickel particle, and nickel oxide is contained by 5 to 20 wt.% in the whole metal in metal conversion. Desirably in an electronic part having an internal conductor in a dielectric, nickel oxide exists on an interface between the dielectric and the internal conductor. A shape of the base metal particle is a spherical shape, a flake shape, a projection shape or an undefined shape, the average particle size of the base metal particle is 0.05 to 0.8 μm in a value found by a specific surface area diameter, and a thickness of the nickel oxide covering the surface of the base metal particle is desirably 50 to 300 nm. For example, a nickel oxide layer 3 exists on an interface between a dielectric layer 1 and an internal electride layer 2 in a multilayer ceramic capacitor.  When the base metal particle is covered with the nickel oxide, a degree of sintering nickel is delayed, and the volume is also reduced since the nickel oxide is reduced to nickel to thin the internal conductor.

Abstract: PURPOSE:To save material by cutting off a flat deformed ring body from a raw material plate or sheet in a way of smashing the ring body within a plane including the ring body and deforming the body in a ring shape so as to obtain a desired shape. CONSTITUTION:A speaker gasket 1 being the final product is cut off and a flat deformed ring body 3 in a shape smashing the gasket 1 from a direction in a plane including the gasket 1 is cut off from the raw material made of a foamed highpolymer plate or sheet, and the deformed ring body 3 is deformed into the ring shape being the shape of the final product through the use of the flexibility by using a jig to shape the ring body 3 into the speaker gasket 1 being the final product. Since the speaker gasket 1 keeps the shape of the flat deformed ring body 3 naturally, the gasket 1 is in contact with the template of the shape of the final product to keep the shape as the final product. Thus, the flat deformed ring body 3 is cut off from the raw material to manufacture the product with less material consumption.
