Abstract: PURPOSE:To prevent the burning at the time of molding and suppress the generation of an offensive smell by putting a molding base material of range felt having the upper and lower surface covered with a non-permeating sheet between a pair of metal molds followed by pressurizing and heating molding. CONSTITUTION:A molding base material 2 to be heated and molded is received between a pair of metal molds 11, 12 and molded, with the upper and lower surfaces being covered with a craft paper 5.

Title: Manufacture of thin film el element
Inventor: MATSUNO AKIRA
IPC: H05B33/12
Filed: 1990-09-28
Abstract: PURPOSE:To allow evaporation of respective structural elements stably so as to stabilize the quality of thus obtained emission layer evaporating a metal element and active material for constructing a host material within sulfuric atmosphere, when an emission layer is formed in a film. CONSTITUTION:In order to evaporate a metal element and active material for constituting a host material, a metal not necessary to be subjected to electron beam action (structural element on one side of sulfide) is evaporated by resistance heating method within sulfide atmosphere and at the same time, active material is evaporated to obtain sulfide thin film including active material on a substrate. At this time, a temperature at the time of evaporating a metal element often exceeds its melting point, but since metal vapor evaporates from the surface of molten metal liquid any change in evaporation quantity due to a change of surface shape can not take place. At the temperature of a crucible can be kept constant by a temperature adjustor in this way, evaporation quantity can be stabilized, so that a stable high quantity emission layer with less change in composition in film thickness direction can be obtained.

Abstract: PURPOSE:To reduce leakage current, enhance design efficiency, and attain high output by turning an SiO2 mask in striped shape in the surface bearing directions, and selectively etching with an etchant capable of etching only parts of an active layer. CONSTITUTION:An SiO2 film 5 is etched so as to leave in surface bearing directions. With this used as a mask, selection etching is carried out where an N type InP layer 1 is arranged to be trapezoid-shaped. The width of an InGaAsP layer 1 is adapted to be 2mu and under by the next etching while laser beam spots are arranged to be one. Then selection etching is carried out again and the etching is continued until the rest is turned in mesa shape. After sulfuric acid treatment, an N type InP layer 6 and a P type InPC layer 7 are arranged to grow based on a LPE process. During this process, the N type InP layer 6 grows only in those portions under the active layer 2 and it is not connected with the N type InP layer 1. This construction makes it possible to reduce leakage current and highly contribute toward higher efficiency and higher output. Moreover, since the width of the active layer 2 is arranged to be controlled independently, there is no need to change the width of the SiO2 mask to match with the thickness of the N type InP layer 1 and ensures easy design.
