Abstract: PURPOSE:To join hafnium and a zirconium-base alloy to a satisfactory composite material by combining the zirconium-base alloy to the surface of the hanium by press welding or thermal spraying and joining diffusively both metals in the temp. region where the beta phase of the zirconium-base alloy exists then cooling quickly the joined material.

Title: High tension cold rolled steel sheet for outside plate of motorcar
Inventor: ABE HIDEO
IPC: B21B1/22
Filed: 1980-12-23
Abstract: PURPOSE: To obtain a high tension cold rolled steel sheet for making outside plates of motorcars which are improved in the formability and which seldom produces die scratching, by giving a difference in the surface roughness between the outer and inner surfaces of the steel sheet.  
     CONSTITUTION: A difference of at least ≥0.5μm in the surface roughness Ra is given between the outer and inner surfaces of a high tension cold rolled steel sheet for making an outside plate of a motorcar. Then the steel plate is subjected to a press forming by touching the plate of the rougher surface to the die side and finer surface to the punch side. In this way, the coefficient of friction between the material and the punch is lowered and that between the material and the die is raised, and thus, the strain propagation property of the material at the bottom surface of the punch is increased. Owing to the surface character of the steel sheet, the formability at the time of press forming is improved and the die scratching seldom takes place, and, therefore, inferiority in shape as the outside plate of motorcar is eliminated.

Title: Film formation method
Inventor: WATANABE KENJI
IPC: H01L21/205
Filed: 1991-07-24
Abstract: PURPOSE:To restrict the numbers of particles produced during the film formation step while keeping the evenness in the film thickness by a method wherein a wafer loading boat is intermettently rotated during the film formation step on the semiconductor substrate surface. CONSTITUTION:A boat 1 loaded with semiconductor substrates is inserted into a furnace kept at specific temperature to be vacuumized. Next, when the boat 1 reaches the specific degree of vacuum, the gas to be a thin film material is fed to the boat 1 through an injector 6 so as to form a specific film. At this time, e.g. at the time point when half of the full film formation time elapsed, the wafer loading boat 1 is rotated by 180 degrees at the rate of 1rpm by a rotation introducing mechanism 7 later to form the films during the residual time. Through these procedures, the rotary rate can be restricted to the degree capable of keeping the evenness in the film thickness for reducing the rotary time producing the particles thereby enabling the numbers of particles produced to be restricted to the number not exceeding 15.

Filed: 1986-08-06
Abstract: PURPOSE:To identify whether a video signal recorded on a magnetic disk is that of a field picture or that of a frame picture by comparing the comparison result of the levels of the read signals of two magnetic heads with a prescribed reference value and outputting a field/frame decision signal. CONSTITUTION:When the read signals of the magnetic heads 10A, 10B are substantially the same forms, namely, at the time of a frame recording, the output of an error amplifying circuit is substantially near to zero and accordingly, the output of a comparison amplifying circuit 20 goes to an H level. When the magnetic heads 10A, 10B read the field recording signals of respective different still pictures, the output of the error amplifying circuit 16 is divided into a positive and a negative. Then, since this is inputted to the comparison amplifying circuit 20 as a positive signal of a corresponding level, this input signal is generally higher than a reference voltage Vref and accordingly, the output of the circuit 20 goes to a signal of an L level. The output of the comparison amplifying circuit 20 indicates the decision result of the field/frame recording and this signal is fed to a reproducing circuit 21 and used for controlling a reproducing processing therein.
