Title: Method and device for controlling power supply output
Inventor: ISHIWATARI NOBORU
IPC: H02J1/00
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To perform control so that a power supply card constantly operates within a stable region of an output voltage by allocating each different numeric value regarding the number of packaged current cards and performing output control according to the number of packaged cards so that a voltage can be outputted to cards when the number of packaged cards exceeds the numeric value. SOLUTION: A power supply card address signal and information on the number of packaged cards are compared and judged by a secondary side output control part 4. Then, a secondary side voltage output part 5 performs the on/off control of the output of the secondary side voltage of a power supply card based on the output of the secondary side output control part 4 and allows the secondary side output parts of a plurality of power supply cards to be connected in parallel. As a result, since the number of power supply cards can be increased or decreased according to the increase or decrease of the number of packaged cards that are packaged on a shelf and become a load, control can be made so that the packaged power supply card can constantly operate under load current conditions required for stabilizing an output voltage.

IPC: C30B31/22
Filed: 1990-08-01
Abstract: PURPOSE: To manufacture a single crystal layer of a material having a large number of the kinds of lattice constants by epitaxial-depositing a specified thickness layer of a material, comprising different lattice constant on a layer of material having a specified lattice constant, ion-implanting so that one region where transposition expansion is limited is formed, and epitaxially depositing a layer of the same material on that layer. CONSTITUTION: On a substrate 1 or the first layer of a material comprising a pre-determined lattice constant, a second layer 2, having thickness (e) for control of a material having a lattice constant different from the substrate epitaxially grown. The thickness of the layer 2 is determined by the kind of the ion used between the energy and the next step of ion implantation. When an ion implantation 3 is performed at that place or in other devices, a transposition sticking point is generated so that an interfering region 4 is formed. After ion implantation, epitaxy is restored to a thickness E by using the same material as the second layer. The restoration is performed at a lowest temperature for preventing the disappearance of defects which have been generated intentionally. This sample has an end layer 5 of a normal thickness E.

One or two or more kinds out of Fe, Co and Ni are used as the transition metal. Then, a rust-preventing agent and the main agent of an epoxy resin are added to the magnetic powder. They are mixed. A rust-preventing film and an epoxy resin film are formed on the magnetic powder. After a weighing operation, the magnetic powder is kneaded with a bonder resin for several minutes; a hardener and a hardening promotor for the epoxy resin are added. Thereby, the rare earth-transition metal-boron- based magnetic powder is dispersed nearly uniformly in the flexible binder resin. A magnet blank is crushed, rolled and cut. A magnetic field is applied; the blank is magnetized. A heat treatment is executed in order to raise a rare earth bonded magnet to 60 to 200 deg.C and to return it again to room temperature and it corresponds to a so-called heat aging operation.
