摘要:
The aim is to provide a sealed secondary battery with an electrode body that is larger in volume and thus incapacity, without affecting the operability of a valve member and the battery hermeticity. To achieve the aim, the sealed secondary battery includes an electrode body, an external casing, a closure plate, and a valve member. The external casing is of a tubular shape having a bottom and an opening. The closure plate has a hole formed through a central portion thereof and is secured at a peripheral portion to the edge of the opening of the external casing. The valve member has a resilient portion and a plate portion. The plate portion is biased by the resilient portion against the closure plate to close off the hole. The closure plate is smaller in average thickness at portions opposite a main surface of the plate portion than at other portions.

On a GaAs substrate (Al.sub.Y Ga.sub.1-Y).sub.0.5 In.sub.0.5 P crystal layers (0.ltoreq.Y.ltoreq.1) is formed to be lattice-matched with the substrate. By radiating As molecular beams on the surface of the crystal layers while heating the layered substrate to a temperature at which In in the crystal layers evaporates, the portion near the surface of the crystal layers is changed into an Al.sub.Y Ga.sub.1-Y As crystal layer (0.ltoreq.Y.ltoreq.1) of a thickness of several molecules, on which layer an Al.sub.X Ga.sub.1-X As crystal layer (0.ltoreq.X.ltoreq.1) is formed. Since the surface of the Al.sub.Y Ga.sub.1-Y As crystal layer has been purl fled, the formed Al.sub.X Ga.sub.1-X As crystal layer has a high crystallinity, allowing production of a light emitting diode, a semiconductor laser device and the like with high efficiency.

摘要:
A normally operable decoder circuit is obtained without entailing a delay in decoding operation, an increase in circuit area, and an increase in circuit design cost. An NMOS transistor in a high-voltage circuit portion is inserted between the output of a NAND gate and a node, and receives an input signal at the gate electrode thereof. A load current generating portion in the high-voltage circuit portion includes PMOS transistors coupled in series between a high power supply voltage and the node. One of the PMOS transistor receives a control signal at the gate electrode thereof. The other PMOS transistor receives a control signal at the gate electrode thereof. An inverter receives a signal obtained from the node as an input signal, and outputs the inverted signal thereof as an output signal.

A semiconductor memory device includes an inner circuit. The inner circuit includes a command user interface, a logical circuit and a pad. Based upon an externally input fixing command, the command user interface outputs signals A and B with H or L level. Upon receipt of the signal A of H level and the signal B of L level, the logical circuit outputs a fixed logical signal of H level independent of the signal received from the pad, and upon receipt of the signal A of L level and the signal B of H level, outputs a fixed logical signal of L level independent of the signal received from the pad. Thus, it becomes possible to carry out a high-quality testing operation even when the number of the test pins of a test device is smaller than the number of address pins or data pins of a semiconductor memory device.
