Title: Manufacture of semiconductor laser
Inventor: YOSHIKAWA AKIO
IPC: H01L21/208
Filed: 1985-11-05
Abstract: PURPOSE:To prevent the impurity in the substrate of a semiconductor laser of an internal stripe structure from being diffused into a current blocking layer by providing a buffer layer between the substrate and the current blocking layer. CONSTITUTION:After a P-type low-impurity concentration (or nondoped or N-type) GaAs buffer layer 10 and an N-type GaAs current blocking layer 2 are formed by a epitaxial growth method, a V-groove with an internal stripe width (w) is formed by photolithography. Then a P-type GaAlAs cladding layer 4, a GaAlAs active layer 5, an N-type GaAlAs cladding layer 6 and an N-type GaAs cap layer 7 are formed by an LPE method and electrodes 8 and 9 are formed. As the buffer layer 10 exists, even if Zn in the substrate 1 is diffused in the forming process of each layer, the quantity of Zn which is diffused into the current blocking layer 2 is very little. Therefore, the current blocking effect of the layer 2 is ensured so that a laser with a low threshold current can be produced with high reproducibility.

Filed: 1989-09-26
Abstract: PURPOSE:To decide that a heat-sensitive magnetic recording medium is true when color developing does not happen, by a method wherein less-color-developing areas are provided at some positions on a heat-sensitive color developing layer, and the information on the positions of the less-color-developing areas is recorded on a magnetic recording medium. CONSTITUTION:A material containing leuco dye, acid color former and binder resin is used for heat-sensitive color developing layers 8 and 8'. For color development inhibitory layers 9 and 9', a kind of resin is used, which has a glass transition point lower than the melting point of the color former contained in the heat-sensitive color developing layer. The color- development inhibitory layers 9 are formed in contact with a shield layer 6, and the color development inhibitory layer 9' is formed in contact with a base material 2. The color development inhibitory layers 9 and 9' are not provided on the whole surface of a card but only in particular areas. The color development inhibitory layers 9 are provided only in particular areas R1 and R2, and the color development inhibitory laser 9' is similarly provided. The color developing layers 8 and 8' develop color by heating with a normal heat amount, except for areas where the color development inhibitory layers are located, however, the areas where the color development inhibitory layers 9 and 9' are located do not develop color substantially by heating with the same heat amount as the normal one because the color development inhibitory layers 9 and 9' absorb heat to change their form before the color former reaches the melting point.

Title: Production of silver halide photographic emulsion and production of silver halide photographic sensitive material
Inventor: TAKADA HIROSHI
IPC: G03C1/035
Filed: 1990-09-18
Abstract: PURPOSE:To lessen fogging and to enhance sensitivity by incorporating >=2% dispersion medium having a protective colloidal property into an emulsion consisting of silver halide particles having fine sizes and specifying the volume thereof. CONSTITUTION:This emulsion is formed by incorporating >=2%(wt/vol) dispersion medium having the protective colloidal property into the emulsion consisting of the silver halide particles having the fine sizes and specifying the volume thereof to <=1,500 mol/1mol silver. Namely, the fine particles free from flocculation are formed by increasing the dispersion medium content having the protective colloidal property of the fine particle emulsion. Then, the flocculation of the fine particles does not arise and further, the grain size of the fine particles decreases even when the fine particle emulsion is thickened. The high solubility is thus obtd. The volume per 1mol silver of the fine particle emulsion for supply is reduced by the concentrating of the fine particle emulsion and the fining of the fine particles, by which the production efficiency is improved. The silver halide emulsion which is low in fogging and has the high sensitivity is obtd. with the high production efficiency in this way.
