Title: Extension system for input-output buffer
Inventor: KOUCHI JUICHI
IPC: G06F13/38
Filed: 1990-10-05
Abstract: PURPOSE:To prevent the occurrence of an overrun in data transfer by providing a common extension buffer which can be inserted on both of an output or input sides. CONSTITUTION:An extension buffer 3 is constituted in such a way that a system from an input port E1 to an output port E3 and another system from an input port E4 to another output port E2 can be switched to each other by means of an extension control signal 10 to a control terminal EC. An I/O control circuit 1 monitors the data transferring amount between an output side and input side and, when a possibility of an overrun is recognized on one side, issues the extension control signal 10 for inserting the buffer 3 on the side where the possibility is recognized. Therefore, either an output buffer 4 or input buffer 5 can be extended in corresponding to a change in data transmitting amount on the output or input side and the occurrence of an overrun in data transfer can be prevented.

Title: Sealed alkaline storage battery
Inventor: IWAKI TSUTOMU
IPC: H01M10/34
Filed: 1986-11-12
Abstract: PURPOSE:To retard an increase in the internal pressure of a battery in quick charge and prevent a drop in discharge voltage by forming a conductive layer on one side of a negative electrode, and facing the conductive layer to a positive electrode, then spirally winding them. CONSTITUTION:A positive electrode 2 and a negative electrode 1 are spirally wound via a separator 3. A conductive layer is formed on one side of the negative electrode 1, and faced to the positive electrode, then they are spirally wound. By this construction, the absorption capacity of oxygen gas evolved from the positive electrode is increased. The diffusion of an electrolyte in high rate discharge at low temperature is sufficiently conducted from the side, on which no conductive layer is formed, of the negative electrode. Therefore, a drop in performance in this discharge condition can be prevented.

IPC: H01L21/302
Filed: 1985-11-29
Abstract: PURPOSE:To obtain an etching mirror laser whose two end surfaces are approximately vertical and realize the characteristics which are by no means inferior to the characteristics of a laser with mirrors formed by cleaving and, moreover, eliminate a cleaving process by a method wherein the end surface of a resonator are formed by inclining the junction plane of a P-N junction against the direction of ion beam irradiation. CONSTITUTION:A specimen is placed aslant to have an inclination angle theta1 of 40-50 deg. and the one side of an etching mask 1 is held vertically to the direction of ion beam application and inclined etching is carried out to form the 1st end surface with a steep angle of about 90 deg. (vertical). After the steep 1st end surface is protected by the 2nd etching mask 8 (TiO2), the specimen is inclined to have the 2nd inclination angle theta2 of 40-50 deg. to the direction opposite to a 1st inclination angle theta1 to make the other end surface a steep 2nd surface so that the vertical etched surfaces can be obtained at both ends. A semiconductor laser device which is obtained like this and has vertical etched surfaces at both ends shows excellent characteristics.
