Title: Method and device for automatic welding
Inventor: TAKANASHI KENICHI
IPC: B23K9/095
Filed: 1989-06-12
Abstract: PURPOSE:To eliminate the stepwise change in welding conditions and to improve welding quality by determining an interpolation curve in accordance with the welding conditions between respective welding sections and previously specified conditions and controlling the welding conditions based on this interpolation curve. CONSTITUTION:A control section 1 has a welding condition setting section 2 which sets the welding conditions, an equation specifying section 3 for specifying the kind of the interpolation curve and a calculating section 4 which calculates the interpolation curve based on specified equation. The control device consists of a control section 5 which controls a welding power source 6 and a torch driving device 7 in accordance with the calculated interpolation curve. An interpolation curve is determined by connecting continuously welding conditions set at each welding sections. Welding is executed while the welding conditions are continuously changed in accordance with this interpolation curve. The welding of Al, copper, etc., with which a thermal change is large is automated in this way. The bead width and depth of penetration are thus maintained constant and the workability and welding quality are improved.

Title: Preventing method for crack in ingot in curved continuous casting
Inventor: SASAKI TOMOHISA
IPC: B22D11/12
Filed: 1979-11-14
Abstract: PURPOSE:To prevent internal cracking securely by removing generated scale sticking to the surface of an ingot by a scale removal device provided to the front surface of a pressing roller. CONSTITUTION:Ingot 4, carried as shown by arrow (a), reaches scale prevention device 6 on the front face of pressing roller 5. Scale prevention device 6 consists of brush roll 6a that rotates in contact with the surface of ingot 4 and driver 6b that rotates brush roller 6a and brush roll 6a rotates in contact with ingot 4 to scratch the scale on the surface of ingot 4 off.

Title: Electrophotographic receptor
Inventor: YASHIKI YUUICHI
IPC: G03G5/147
Filed: 1980-10-22
Abstract: PURPOSE:To enhance the durability and cleanability by forming a hardened film of water-soluble silicone resin which is silicone resin-polyester resin copolymer as a protective layer on the photoconductive layer. CONSTITUTION:A photoconductive layer is formed by dispersing powder of a photoconductive substance such as CdS, ZnO or TiO2 in a binder resin to obtain an electrophotographic receptor. At this time, on the photoconductive layer a hardened film of water-soluble silicone resin which is silicone resin-polyester resin copolymer is formed as a protective layer. By copolymerizing silicone resin with polyester resin, many hydroxyl groups are provided to the molecular chain, the reactivity is enhanced, and the copolymer is made soluble in water. Since water is used as a solvent for the water-soluble silicone resin, the resin can be applied to the photoconductive layer, and the protective layer can be formed by baking at a relatively low temp. This receptor can be cleaned with a blade, and the deterioration in the photoconductivity can be reduced.

Abstract: PROBLEM TO BE SOLVED: To prevent an internal combustion engine from non-restartable by prohibiting the execution of automatic stop control by an automatic stopping and starting means while no traveling hysteresis of a vehicle is judged by a traveling hysteresis judging means after the start of the internal combustion engine. SOLUTION: In an automatic stop control routine during the operation control of a vehicle by an ECU 22, output signals of various sensors stored in a RAM, for example, engine speed, vehicle speed and the like are inputted. It is judged whether '1' is stored in a stop and start prohibiting flag memory area within a backup RAM or not, and '1' is stored in an automatic stop control flag memory area or not. When YES is judged for the both, it is judged that automatic stop control is never executed after the manual start of an internal combustion engine, and no traveling hysteresis of the vehicle is judged from the output signals such as vehicle speed, shift position and engine speed, the execution of the automatic stop control is prohibited.

Abstract: PURPOSE:To reduce the manufacture cost of the title device by forming images of light from a high-density array type light emitting element unit and reflected light from a document on a photo-sensitive body by sharing one rod lens array. CONSTITUTION:When a printer mode is entered by switching, a solenoid 23 is switched off and the high-density integrated LED array unit 22 is moved by a spring 24 to an entry position B to the optical path of the light so that its image is formed on the photosensitive drum 5 through the rod lens array 4.

At this time, the high-density integrated LED array is so arranged that the optical path distance from the light emission point of the LED array to the rod lens array 4 is equal to the optical path distance from the illumination lamp of an illuminator to the rod lens array. Then the LED array unit forms the image on the photosensitive drum 5 through the rod lens array 4 with a printing signal to form a desired electrostatic latent image. Thus, the rod lens array 4 is shared to reduce the manufacture cost of the device.
