Abstract: PURPOSE:To obtain a sufficient density value even with a composition which can be hardly made highly dense by means of a conventional sintering method by a method wherein a desired composition of an alloy whose basic components are rare-earth elements (including Y), iron and boron is cast and crushed and a crushed substance is pressed densely by using a pseudo HIP apparatus. CONSTITUTION:A desirable composition for a permanent magnet is to be composed of 8-30atomic% rare-earth elements, 2-28atomic% boron and iron as a remaining part. An alloy of a desired composition is cast in a mold made of iron at 1500 deg.C in an atmosphere of Ar by using a high-frequency smelting furnace; an ingot is obtained. This cast alloy is crushed down to an average particle diameter of, e.g., 6mum by using a disk mill or a ball mill; the crushed substance is molded in a magnetic field to form a lump; the lump-shaped substance is subjected to pseudo HIP at 1000 deg.C and is made highly dense. During this process, a cycle of the pseudo HIP is 40 seconds.

Title: Power supply circuit of electronic apparatus
Inventor: TOKUKASA FUMIO
IPC: H02M3/00
Filed: 1994-12-24
Abstract: PURPOSE: To quickly disable supply of current to a heavy load when a battery is consumed by directly detecting the drop of battery voltage with an analog comparator and cutting off a current supply path to the heavy load with such a detected output. CONSTITUTION: When a switch S2 is depressed to allow a current to flow into a heavy load 3, voltage of a battery 1, if it is already exhausted considerably, is quickly lowered and thereby an input of the comparator 7 is also lowered. Thereby, an output of the comparator 7 rises to a battery voltage from the zero level and is then applied to the emitter of a transistor Q. Accordingly, the transistor Q is inversely biased to becomes off. Thereby, FET 2 also becomes off, cutting off the power supply path to the heavy load 3 from the battery to stop the power supply. Thereby, current supply to heavy load can be stopped quickly when the battery is already exhausted.

IPC: G11C16/04
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To suppress the holding characteristic from deteriorating due to the write/erase repetitions by taking a distance greater than the thickness of a gate insulation film between the end of a floating gate and a source region surface. SOLUTION: For a flash memory cell is set at a distance L1 3.6-5.5 times a thickness W of a gate oxide film 103 between the end of a floating gate FG electrode 104 and source region 108 surface. In prior art, the write/erase operation concentrated the electric field on the end of this electrode 104 to cause a local current flow at the erase operation, resulting in a sharp deterioration of this area and hence deterioration of the hold characteristic. With the increase of the distance L1 between the FG end and source region surface, more than the gate oxide film thickness W, the field concn. on the end of the electrode 104 is relaxed to suppress the holding characteristic deterioration after the repetition of the write-erase operations, without while restraining erase speed.
