Title: Power saving method for information processor and information processor having power saving function
Inventor: SUDO TAKAYUKI
IPC: G06F1/32
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To switch a power saving state and a power non-saving state through any simple means at an information processor, which enables tablet inputting, and further to avoid accidental switching without using any protecting means such as a cover. SOLUTION: When a symbol for the switching of power saving state and power non-saving state is inputted to a tablet panel 11, a discrimination circuit 25 compares a switching symbol previously stored in a symbol memory 30 with the real input symbol. When both the symbols are almost coincident with each other, a power saving circuit 26 performs the switching of power saving state and power non-saving state. By using the symbol as a switching means, accidental switching can be avoided.

Title: Power supply
Inventor: SATO YASUHIRO
IPC: H02J1/10
Filed: 1994-12-08
Abstract: PURPOSE: To prevent power supply fluctuation and erroneous operation of a load unit, for which the power supply is recovered, during initial charging operation by holding each load unit in waiting state after receiving power from a precharge power supply before power supply to an OR circuit section from a main power supply. CONSTITUTION: An OR circuit section 41 selects a precharge power supply Pab or a main power supply Mab, having a higher voltage, ap an OR power supply for feeding power to a microcomputer 44. A reset section 45, being operated by the precharge power supply Pab, delivers a reset signal (r) to the microcomputer 44 until power is received from the main power supply Mab and holds a controller 21 in waiting state. When the controller 21 is drawn out from a rack for the purpose of maintenance and then the power supply is recovered, the precharge power supply Pab feeds power to the microcomputer 44 through the OR circuit section 41 thus charging the controller 21 initially. Since the controller 22 is operated by the main power supply Mab, the power supply does not fluctuate and the erroneous operation is prevented.

Title: Smelting reduction method for iron ore
Inventor: IWASAKI KATSUHIRO
IPC: C21B13/00
Filed: 1988-12-28
Abstract: PURPOSE:To prevent explosion caused by unreacted O2 remaining in a furnace at the starting time of blowing and to stabilize OD ratio at high level by making the pressure in the furnace atmospheric pressure during the specific period at the starting time of the blowing in the subject method with iron bath type smelting reduction furnace. CONSTITUTION:Iron ore and carbonaceous material are supplied in the reduction furnace 1, and O2 is blown on slag 8 through a lance 2 inserted in the furnace 1 at low dynamic pressure, and stirring gas of N2, etc., is blown into the iron bath 7 through blowing holes 3 arranged at the bottom and/or side wall of the furnace. Then, C in the molten iron and C in the carbonaceous material are reacted with the blown O2 to change the generated CO into CO2 and the iron ore is reduced and changed into the molten iron. In this case, at the time of starting the blowing, the pressure in the furnace 1 is substantially made to the atmospheric pressure until CO gas is generated sufficiently. By this method, as decarburizing effect in the molten iron with the blown O2 becomes high, the unreacted O2 can hardly exist in the furnace and in this result, the gas explosion in the furnace can be prevented. After that, as the furnace operation is executed while making the pressure in the furnace high, the lowering of the OD ratio does not occur.

Title: Superconducting coil and its manufacture
Inventor: KAMINAMI SEIJI
IPC: H01B13/00
Filed: 1987-12-29
Abstract: PURPOSE:To obtain a superconducting magnet having high critical current density by a method wherein a coil consists of a base and at least one layer of oxide superconductor film laminated on the base, and the oxide superconductor film is lengthened by an extremely narrow spiral groove. CONSTITUTION:A coil consists of a base 1 and at least one layer of oxide superconductor film 2 laminated on the base 1, and the oxide superconductor film 2 is lengthened by a spiral groove 3 of extremely narrow width. Since the superconductor is formed by the film forming technique, the directions of crystal axes can be aligned so as to improve the critical current density. In addition, since use of laser trimming enables accuracy of micron order to be controlled, a large number of turns can he increased in a limited size. Multilayering the superconductor thin film contributes to increase in the number of turns. This realizes a compact superconducting coil having high critical current density which can generate high magnetic field.
