Title: Oscillate welding method
Inventor: MUNEYUKI TADASHI
IPC: B23K9/127
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To allow the oscillate center position to follow the weld seam with excellent accuracy, and to prevent deviation or undercut of the bead by the oscillate welding method in which the oscillate center position is corrected by the quantity of correction in the direction of the groove width for each control period. SOLUTION: An oscillate mechanism 6 to oscillate a welding torch 2 holding a welding electrode 1 between groove walls 3a of a work 3 so as to be orthogonal to a weld seam 5 is provided. When the welding torch 2 is oscillated, the projection length of the welding electrode 1 becomes shorter as an oscillation end is closer to the groove walls 3a, the resistance is reduced, and the welding current is increased. The deviation of the oscillate center position to the weld seam is detected by comparing the welding current values corresponding to right and left ends of the oscillation, and the oscillate center position is corrected thereby. The oscillate center position follows the weld seam 5 with excellent accuracy, and generation of the undercut or blow holes at the bead end part can be prevented.

Title: Manufacture of laminated ceramic chip capacitor
IPC: H01G4/30
Filed: 1992-04-03
Abstract: PURPOSE:To reduce the particle size of sintered-body particles by a method wherein the oxygen partial pressure of a baking atmosphere at least in one part or the whole of a temperature rise part in a baking operation is made lower than an oxygen partial pressure in a temperature maintaining part. CONSTITUTION:A paste used for internal electrodes 21, 25 and a paste used for dielectric layers 3 are laminated alternately by a printing method, a transfer method, a green sheet method or the like; after that, this laminated body is cut to a prescribed laminated-body size. Then, a binder-removing treatment and a baking operation are executed; a heat treatment which is used to reoxidize the dielectric layers 3 is executed. For a baking condition at this time, a mixed gas of N2 and H2. which have been humidified is used as a gas for atmosphere use, and the oxygen partial pressure of a baking atmosphere is lowered to 10<-2>atm or lower when a temperature rise part is 1100 to 1300 deg.C. A heat treatment which is executed in succession is executed at a holding temperature or a maximum temperature of 800 to 1200 deg.C. Thereby, even by using a dielectric whose interlayer thickness is thin, it is possible to manufacture a laminated ceramic chip capacitor in which the particle size of sintered-body particles is small, whose life, is long and whose initial insulation resistance is high.

Filed: 1986-05-15
Abstract: PURPOSE:To stabilize the electrical characteristics of a semiconductor integrated circuit by connecting >=3 transistors (TR) in parallel to the collector of the 1st TR forming a current mirror. CONSTITUTION:The current flowing to (n) TR groups 9 connected in parallel is supplied to the 5th TR5 by the 1st and 2nd TR1 and TR2 forming a current mirror. The collector currents of both TR1 and TR2 are shown as a function of the number of TR connected in parallel and the base-emitter voltage, i.e., the saturated current of each TR. Thus the variance of the saturated current is compensated by securing parallel connection of >=3 TR. Then the variance of the collector current of the 2nd TR can be avoided.

Filed: 1989-04-28
Abstract: PURPOSE:To prevent scattered oil during cooking from igniting on other heater unit by providing means for inhibiting energization of the other heater unit during execution of a cooking mode of fried food for controlling one heater unit by automatic temperature control means. CONSTITUTION:A signal of an oil temperature sensor 11 immersed in oil 8 is input to a control circuit 16.

On the other hand, if another cooking is already performed by the unit 2 before cooking is started, its input is put into pulled state even if the 'input' key of the unit 2 is operated. Thus, oil scattered during cooking is not ignited on the other unit and not burned.

Abstract: PURPOSE:To branch the light signal of optical transmission to several signals by providing freely slidably the input end side of plural pieces of optical fiber bundles to the output side end of one optical fiber. CONSTITUTION:A light signal advances like an arrow in an optical transmission fiber cable 51 on an input side, passes through respective optical fibers 55, 56 at a 1:1 ratio at the end faces 51a, 52a in contact with said cable, and is transmitted through end faces 53a, 55b, 56b to optical transmission fiber cables 53 on an output side.
