Abstract: PURPOSE:To form a cladding metal into a flat shape and to improve the yield of a product by providing preliminarily convex-shaped projecting parts and thick-walled parts corresponding to erroding proportions to the base part and both transverse ends of the cladding metal just above a flowoff port. CONSTITUTION:The projecting part 2 at the base of the cladding metal 1 is so formed as to have the largest projecting length (e) of the part 2 in the part just above the flowoff port where a molten steel contacts directly with the metal 1, i.e., near the center in the transverse and thickness directions of the metal 1 and to have the narrower width the nearer the top end. The thick-walled parts at both transverse ends 3, 3a are constituted of the thick-walled parts (f) expanded into a tapered shape in the thickness direction of the material 1 and the lateral projecting parts (g) projecting respectively into a convex shape to the side faces of the ends 3, 3a. The cladding metal is thus made into a flat shape and the yield of the product formed by rolling after casting is improved.

Filed: 1979-07-30
Abstract: PURPOSE:To flatten and clean up the surface of a diffusion layer without putting a substrate at a high temperature, by using plasma of oxidizing gas to oxidize the surface of the diffusion layer. CONSTITUTION:An SiO2 film 2 is provided on the surface of N-type Si substrate 1.  B is diffused through the opening of the film 2 to produce a P<+>-type layer 3. The  surface of the layer 3 has projections and recesses because fine Si-B compound grains 4 are generated on the surface. Mixed plasma of steam and O2 is supplied to the substrate to oxidize the surface of the layer 3. Since the activity of the plasma is high, an amorphous substance 5 containing SiO2 and B2O3 mixed with the other is produced on the surface of the layer 3. The substance 5 is removed to eliminate the projections and recesses to flatten the surface of the layer 3 and remove crystal defects etc. from the surface. The surface of the layer is thus improved. A base and  an emitter regions are then provided to manufacture a transistor of good properties.

Title: Automatic pump
Inventor: TAKI TOMOHIKO
IPC: F04D13/16
Filed: 1979-08-01
Abstract: PURPOSE: To prevent increase in frequency in pump starts and stops by providing a check valve at a pump inlet in such a manner as to release the amount of water in response to the pressure at the pump inlet.  
     CONSTITUTION: A check valve 3 is located at the inlet side of a pump, whose valve 31 is linked to a diaphragm 45. Pressure on the inlet side is working on one end of the diaphragm whereas atmospheric pressure is applied to the other end. Opening of the valve 31 is then regulated by the pressure on the inlet side. Thus, as the amount of water to be lifted is increased, such as in a pressure feed stage, the valve 31 exerts a resistance to the flow of liquid according to the amount of lift. This places a limit on the increase in the liquid flow, thereby making the frequency in pump starts and stops constant.

Abstract: PURPOSE:To enable the amount of intake surrounding air to be controlled in less-expensive and accurate manner without using any CO2 sensor by a method wherein a degree of opening of a damper corresponding to an amount of intake surrounding air is set for every specified unit of time according to the concentration of CO2 which is set in advance, a degree of opening of the surrounding air damper corresponding to a reduced amount of air, a degree of opening of the surrounding air corresponding to the reduced amount of air is corrected to control the degree of opening of each of the dampers. CONSTITUTION:In general, concentration of CO2 follows the number of occupants in a room. This concentration is divided by a unit of specified time and set as an amount of intake surrounding air, i.e. a degree of opening of a damper. An air circulating fan 1 and an air feeding fan 7 have variable number of rotation set through an inverter and the like. A required amount of air is determined according to condition of an indoor load and the like and correspondingly the number of rotation of each of the fans is determined. The degree of opening of the damper is corrected by a surrounding air damper correcting biasing degree of opening setting means 12 stored in a controller 13 in accordance with the number of rotation of each of the air feeding fan 7 and the air circulation fan 1. So, even in case that the number of rotation of each of the fans is varied through the CO2 sensor inverter and the like, it becomes possible to perform an accurate control over an amount of intake surrounding air.
