Title: High potential level compensating circuit
Inventor: SHIMIZU TAMIO
IPC: G11C11/407
Filed: 1984-05-30
Abstract: PURPOSE:To operate a semiconductor storage device without mistake immediately after holding, by compensating a high potential level by utilizing a high potential level made by an oscillator contained in the semiconductor storage device, as a power source, with regard to an internal signal being the high potential level in the course of a holding period. CONSTITUTION:A periodical signal phin for repeating periodically a high potential level and a low potential level is outputted from an oscillator which is not shown in the figure, and the periodical signal phin is inputted to a connecting point M through a capacity C. When the periodical signal phin goes to a high potential level, the connecting point M goes to a very high potential level by the capacity C, a transistor Q22 turns on, and a level PG goes to a level exceeding a power supply voltage. It is repeated and the high potential level of the signal PG is always maintained. Even if the charge is decreased due to the cause of a leak, etc. of a nodal point N after a holding state of many hours, the transistor Q23 turns on when the potential goes to a degree of a power source, and the high potential level of the nodal point N is compensated by the transistor Q23.

Title: Superconductive device
Inventor: NISHINO JUICHI
IPC: H01L21/82
Filed: 1985-05-24
Abstract: PURPOSE:To make the device planar, by providing with two impurity introduced sections for reducing Schottky barrier on a semiconductor substrate, and by making a low-concentration impurity layer between them, being a thickness such that the layer can not project from the surface of a superconductive electrode. CONSTITUTION:After an oxide film 2 is formed on a semiconductor substrate 1, a protrusion 3 is formed by etching. After impurities are diffused into the entire face to form a diffusion layer 4, an Nb film is evaporated. Next, the Nb film is treated, using a photo resist pattern as a mask to form superconductive electrodes 5, 6. In this way, since the surfaces of the protrusion 3 and the superconductive electrodes 5, 6 are made into approximately same heights, this device can be made planar. Thereafter an insulating film is formed and then a control electrode 8 is formed.

Title: Hydrogen storage alloy
Inventor: TOWATA SHINICHI
IPC: H01M4/38
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a pulverizing phenomenon during use by incorporating Yb into an alloy with CaCu5 type crystal structure or MgZn2 type crystal structure, being used as an electrode-activating material for secondary battery and capable of reversibly occluding and releasing hydrogen. SOLUTION: An alloy, prepared by adding Yb by 1 wt.% to an (La, Ce, Ne, Pr) (Ni, Co, Mn, Al)5 composition of CaCu5 type alloy structure, is produced. Further, in the case of an alloy with MgZn2 type crystal structure, Yb is added by 5 wt.% to a (Zn, Ti) (Ni, Mn, V, Cr)2 composition. With respect to a nickel- hydrogen battery cell using the Yb-added alloy with CaCu5 type crystal structure as a cathode, practically no reduction in discharge capacitance is observed and the structure is in a coarse-grained state at 120-times charge and discharge cycle tests at room temp. and at 50 deg.C; on the other hand, in the case of a Yb- free alloy, discharge capacitance is decreased with the increase in the charge and discharge cycle and also the structure becomes fine-grained (pulverized).

Title: Soft aluminum foil for anode of electrolytic capacitor
Inventor: MATSUOKA HIROSHI
IPC: H01G9/04
Filed: 1992-04-30
Abstract: PURPOSE:To make the thickness of an oxide film formed on the surface of aluminum foil having purity higher than a specific level at the time of heat treatment thinner and more uniform so that the surface area expansion rate of the aluminum foil can be improved at the time of etching by mixing a specific amount of lithium in the aluminum foil. CONSTITUTION:The aluminum purity of the title soft aluminum foil is improved to 99.9% and the lithium content of the aluminum foil is controlled to 0.0001-0.05%. When an appropriate amount of lithium is mixed in aluminum, the reactivity of the aluminum to oxygen is remarkably lowered. Therefore, even when such aluminum foil is heat-treated at a high temperature, the growth of an oxide film on the surface of the foil can be suppressed. As a result, the surface area expanding rate after etching can be increased and the thickness variation of the oxide film in the width direction can be suppressed even when the foil is heat-treated in a coil-like state. In addition, the variation of the surface area expansion rate can be effectively suppressed.

In addition, rotation of a rocking motor 8 is converted into displacement motion by an eccentric cam 9, thereby rotating a turning shaft 11 as in an arrow (c). A cylinder 4 and a mechanismic member rotating this cylinder both are mounted on this turning part. With this turning shaft 11 as a shaft center, the cylinder 4 is rocked up and down as in an arrow (d). Owing to these two operations of rotation and rocking motion, many pieces of the cover glass 2 stuck to the outer circumferential surface of the cylinder 4 are uniformly ground into a curved form at the same time.
