Filed: 1985-06-03
Abstract: PURPOSE:To prevent a grindwheel from breaking and improve grinding efficiency by grinding a ceramics at a high peripheral speed of grindwheel excessing a specified speed dashing grinding fluids from high pressure nozzles to the diamond grindwheel.

Title: Dynamic random access memory

Filed: 1989-05-15
Abstract: PURPOSE:To prevent malfunction occurring and to attain fast access by activating a bit line sense amplifier after reading out the signal of memory cell to a bit line, and controlling an electric charge transfer circuit at an off state after the operation of the sense amplifier. CONSTITUTION:An N-channel sense amplifier NA in a selected block is activated with an activated signal, the inverse of SANj until micro potential difference appears at a pair of bit lines after data in the memory cell appears at the pair of bit lines. After that, one of control signals phiTj goes to ground potential for constant time, and electric charge transfer transistors NT1 and NT2 in the selected block are turned off for the constant time, and a pair of bit lines, BL and the inverse of BL, are separated from the amplifier NA for the constant time. In such a way, a load on a sense node can be reduced, and a fast sense operation can be performed, and also, since the bit line sense amplifier is activated when the load is reduced even when asymmetric property occurs in the sense node, influence due to the asymmetric property is hardly received, and the malfunction can be prevented occurring.

Title: Dc-dc converter
Inventor: MAEDA TOMONORI
IPC: H02M3/155
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To prevent a power loss from existing due to dummy resistor. SOLUTION: A load current is detected through a resistor 15. In case the load current is large, a transistor 16 is on; a transistor 14 is turned on; and a transistor 8 is turned off. Therefore, the oscillation frequency of a switching transistor 3 is set by resistors 6, 7 for setting time constant and a capacitor 5 for the same purpose. In case the load current is small, the transistor 16 is turned off; the transistor 14 is turned off; and the transistor 8 is turned on. Therefore, the oscillation frequency of the switching transistor 3 is set by the resistor 6 for setting time constant and the capacitor 5 for the same purpose, and the oscillation frequency is increased. This makes it possible to prevent discontinuous mode from being generated in a load current even when the load current is small.  In addition, since a dummy resistor is not used, no power less due to dummy resistor is produced.

Title: Production of hydrogen storage alloy powder
Inventor: YANAGIMOTO MASARU
IPC: B22F1/00
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To produce a hydrogen storage alloy powder, remarkably improved in hydrogen occluding velocity, by melting a misch metal - nickel hydrogen storage alloy, atomizing the molten alloy by the use of an inert gas containing specific amounts of gaseous nitrogen, and subjecting the resultant powder to surface treatment with an acid solution. SOLUTION: A misch metal - nickel hydrogen storage alloy is melted, and the resultant molten alloy is gas-atomized by using an inert gas (argon) containing 0.1-<50vol.% gaseous nitrogen. A nitride film is formed on the surface of the powder prepared by atomizing, and this nitride film is composed essentially of rare earths contained in misch metal. When this powder is acid- treated by using a solution of hydrochloric acid, the nitride film is removed from the surface and the Ni-enriched phase right under the surface is allowed to appear at the surface. By this method, the atomized powder excellent in hydrogen occluding velocity can be obtained. This powder can remarkably improve the electrochemical properties when used for electrode.
