Title: Large-output laser amplifier
Inventor: FUJITA HISANORI
IPC: H01S3/22
Filed: 1985-11-06
Abstract: PURPOSE:To bring small signal gains to approximately zero, and to obtain a large output stably by mixing an absorptive medium with a laser amplifying medium approximately uniformly. CONSTITUTION:The amplification characteristics of a laser amplifier are determined by the amplification coefficient G0 of an amplifying medium and saturation energy ES. When the combination and mixing conditions of the materials of an absorptive medium uniformly mixed with the amplifying medium and the amplifying medium are selected properly and alpha=G0 (alpha represents the absorption coefficient of the absorptive medium) holds, the small signal gains of the laser amplifier can be brought to approximately zero. When the materials of the amplifying medium and the absorptive medium are selected more adequately under the conditions of such a zero small signal gains and materials having absorption cross sections sigma' remarkably larger than induced emission cross sections sigma are each selected, the saturation energy ES of the amplifying medium can be enlarged particularly. Accordingly, when stable insulating SF6 gas is added and mixed uniformly to CO2 gas as the amplifying medium, the small signal gains of a CO2 gas-laser device are brought to approximately zero, and internal oscillation easy to be generated with the increase of capacitance is inhibited approximately completely, thus stably attaining the desired augmentation of capacitance.

Inventor: KAMIGUCHI MASAO
IPC: B29C45/50
Filed: 1993-09-09
Abstract: PURPOSE:To eliminate discrepancy in timing between output of a defective signal of a product and actual generation of a defective product, by a method wherein an injection number of times until measured resin is injected afresh within an injection cylinder is obtained, after detection of disorder in measurement, the defective signal of the product is output to a molding cycle wherein injection actions of a set up injection number of times are performed. CONSTITUTION:A number of injection times m until a measured resin is injected first within an injection cylinder 1 and the number of injection times n until the resin is discharged completely are obtained and their values are set up beforehand in a nonvolatile memory 24. When disorder in measurement is detected, a control device 10 watches and waits output of a defective signal of a product until a molding cycle of set up number of injection times is performed, that is, until injection of the measured resin is started afresh within the infection cylinder 1. Then when the molding cycle of the set up number of the injection times is performed and injection of the measured resin within the injection cylinder is started afresh, the defective signal of the product is output by corresponding to the molding cycle.

Title: Charge and discharge circuit of battery
Inventor: MIZUNO YUTAKA
IPC: H02J9/00
Filed: 1987-09-30
Abstract: PURPOSE:To prevent a breakdown of fuse, load and so on by using a semiconductor switch as a switch for breaking the discharge current of a battery. CONSTITUTION:When connected normally, a transistor Tr1 is supplied with a base current by diode D1 and resistance R1 so as to be turned ON, a charging current is caused to flow through a battery B, and a load L is supplied with electric power. Also, when the battery B is discharged, the load L is supplied with electric power via diode D2. In this case, when the battery B is connected in a reversed polarity manner at the time of its exchange, said reversed polarity is detected by resistances R2 and R3 and a transistor Tr2 is reversely biased so as to be turned OFF to stop supplying the transistor Tr1 with a base current. Thus, when the battery B is connected reversely, a discharge current is little and its operating time is short so that a fuse and a load never break down.

Title: Manufacture of split bearing
Inventor: OKAMOTO TOMIO
IPC: F16C7/02
Filed: 1992-09-17
Abstract: PURPOSE:To surely control a rupture starting point, and thereby prevent the occurrence of faulty rupture positions by concentratedly applying load in the direction perpendicularly intersected with the direction of rupture and split to the estimated rupture and split site of a bearing while load in the direction of rupture and split is being applied to the bearing. CONSTITUTION:When a punch 13 is lowered down, prior to the movement of both expansion dies 11 and 12, a right and a left rupturing tip 14 and 15 are forced to bite in the inner circumferential surface of a bearing 2, so that load in the direction perpendicularly intersected with the direction of rupture and split is concentratedly applied to the estimated rupture and split site F of the bearing 2. This constitution thereby allows the site F to which concentrated load by the right and left rupturing tips 14 and 15 is applied, to be easily deformed more remarkably than the other sites while stresses are being concentrated therein. Thus, the occurrence of faulty rupture and split positions can be prevented by applying load in the direction perpendicularly intersected with the direction of rupture and split to the estimated rupture and split site F of the bearing 2 by means of the rupturing tips 14 and 15 while load in the direction of rupture and split is being applied to the bearing 2 by means of both the expansion dies 11 and 12.
