Title: Method for replenishing metallic ion to electroplating liquid
Inventor: MIZUTA SHIGEO
IPC: C25D21/14
Filed: 1985-08-28
Abstract: PURPOSE:To quickly supply metallic ions into a plating liquid and to improve the productivity of a plating line by providing a stirrer in a long-barrel cylindrical body and moving the plating liquid in the cylindrical body and the metallic grains of the metallic ion source so as to face each other, thereby adjusting the superficial velocity of the plating liquid and the stirring speed gradient of the metallic grains to specific values or above. CONSTITUTION:A screw bar 2 for stirring is installed in the long-barrel cylindrical body 1 and the plating liquid from a plating liquid introducing pipe 4 is supplied into the cylindrical body. The bar 2 is rotated to stir the metallic grains for plating in the lower part and while said grains are moved upward to face the plating liquid, the metallic grains and the liquid are brought into contact with each other, so that the metallic grains are dissolved as the metallic ions in the plating liquid. The superficial velocity of the plating liquid expressed by equation [I] is maintained at >=5cm/sec and the stirring speed gradient expressed by formula [II] is maintained at >=500/min, by which the supply of the metallic ions to the plating liquid is made quick and the productivity of the plating line is improved.

Title: Rotary twin-cathode x-ray device
Inventor: NOGUCHI MANABU
IPC: H01J35/10
Filed: 1987-07-29
Abstract: PURPOSE:To further improve the heat resistance of rotary twin-cathodes in a rotary twin-cathode X-ray device by using a specific distributed reinforcement type alloy as the material of the rotary twin cathodes emitting X-rays irradiates with electron beam. CONSTITUTION:A distributed reinforcement type alloy is used as the material of rotary twin cathodes emitting X-rays when irradiated with electron beam, the combination of the host metal and dispersed grains in this distributed reinforcement type alloy is selected so that the wavelength of characteristic X-rays by the dispersed grains is not proximate to the wavelength of characteristic X-rays of the host metal. Hard and fine grains stabilized at a high temperature are dispersed and combined in the distributed reinforcement type alloy, the phase (dispersed phase) of the dispersed grains acts as the barrier against the transition shift, the dispersed phase is prevented from melting into the host metal, thus the temperature dependency of the mechanical characteristic is extremely small, and the initial mechanical characteristic can be maintained without being impaired so much even when heated to the high temperature near the melting point.

IPC: H02P27/06
Filed: 1982-10-27
Abstract: PURPOSE:To return an induction motor to a set speed without overshoot by providing the minimum value selector, thereby accelerating the rise of reacceleration without causing the stepout even if the speed is decelerated due to the abrupt increase in a load. CONSTITUTION:When a load 6 abruptly increases so that a detecting speed 8 rapidly decreases, a correcting set speed 15 to which an added speed 14 is instantaneously applied becomes smaller than the set speed 7, and the output 17 of the minimum selector 16 is switched to the speed 15. Accordingly, the output 17 becomes the value added with the speed 14 to the speed 8, the response of the reacceleration is accelerated, and as the speed 8 increases, the speed 15 increases. When it increases larger than the speed 7, smaller value, i.e., the speed 7 is selected by the minimum value selector 16, and the set speed is returned to the original value.
