Filed: 1982-08-18
Abstract: PURPOSE:To save a labor required for a separating work, by a method wherein, in a printer having variable conveying speed, the slack and tension of a recording paper resulting from a change in a conveying speed is detected, and a slit processing part is actuated in linkage with said detection. CONSTITUTION:When recording to a recording part of a sheet A is completed by means of a printer 1 and a non-recording part comes out, the sheet moves rapidly to cause a slack A'.

IPC: H01S5/00
Filed: 1981-09-12
Abstract: PURPOSE:To provide epitaxial growth layer with little lattice defect, by a method wherein in opposition to the substrate crystal of growing crystal is installed a cover of similar semiconductor, and metal being liquid state at a high temperature is adhered to the cover. CONSTITUTION:If temperature of 700 deg.C is held for about one hour, tin layer 6 adhered to a cover 5 is melted to liquid state, and InP in the cover 5 is melted into the tin and saturated. Phosphorus is liberated out of the tin solution including InP melted therein and the vapor pressure is much higher than InP vapor  pressure in solid state at the same temperature. Therefore between the substrate crystal 4 and the cover 5 is filled with phosphorous vapor and liberation of  phosphorus does not occur at InP to constitute the substrate crystal 4. If melt 3  (solution of In including InP and various impurities melted therein) attains  equilibrium and then the temperature is decreased and a melt vessel 2 (made of  carbon) is transferred onto a slider 1 (made of carbon) in arrow direction, the cover 5 is removed automatically and the melt 3 is coated onto the substrate  crystal 4. As the temperature is decreased, crystal of thin film is grown in  epitaxial state onto the substrate crystal 4.
