Patent JP-H07154163-A (JP)
Title: Differential amplifier circuit
Inventor: ICHIKAWA YUICHI
IPC: H03F3/45
Filed: 1993-11-26
Abstract: PURPOSE:To make an output DC current constant even when an amplification factor is changed by applying a current change just reverse to a current change in an operating current source to a differential amplifier circuit. CONSTITUTION:An emitter area ratio of transistors(TRs) 19, 11, 13 be 1:2:1 and resistance of resistors 21-23 be set to be 2:1:2, then when a current I1 is supplied to a resistor 18, a current 2I1 flows to a collector of the TR 11 and a current I1 flows to a collector of the TR 13. When the resistance of the resistor 18 is changed to change the amplification factor, a current change of I1 being a half of the current 2I1 is produced. A change in the collector current of the TR 13 changes a collector current I2 of the TR 24. The emitter area and the emitter resistance of TRs 15-17 are set equal to each other and the collector current of each TR is I2. On the other hand, a current I1 flows to the TRs 4, 3. Thus, a current I2+I1=-I0-I1+I1=I0=constant flows to output terminals 6, 7. Thus, the DC current of the output terminals 6, 7 is made constant independently of the gain of the differential amplifier circuit.

Title: Processor reset system
Inventor: KITAMURA KOICHI
IPC: G06F1/24
Filed: 1988-11-24
Abstract: PURPOSE:To reduce the burden on a program by giving a time-out signal from a timer circuit to a processor to stop the operation at the time of not giving a reset signal from the processor to the timer circuit and eliminating a need of time management of the reset signal by the processor itself. CONSTITUTION:A time management signal (a) having a certain cycle is always generated from a timer circuit 2 and is given to a processor 1. When the processor 1 is normally operated, a reset signal (b) is generated based on the time management signal from the timer circuit 2 and is given to the timer circuit 2; but when the processor 1 runs away because of the occurrence of abnormality, a time-out signal (c) is generated from the timer circuit 2 and is given to the processor 1 because the reset signal is not given from the processor 1 to the timer circuit 2. Thus, the processor 1 stops the operation to stop runaway.

Abstract: PURPOSE:To increase recording density by forming the thickness of a magnetic layer just above a pit thicker than that of a magnetic layer on a part other than the pit, and detecting the change of a magneto-optical signal between a pit part and a part other than that as an information signal. CONSTITUTION:The pit 105 provided with depth of 200Angstrom  is formed on one plane of a resin substrate 101 in advance. The film thickness 107 of a reproduction layer 103 on the pit 105 is stacked thicker than the film thickness 108 of a part other than the pit 105. When an initializing magnetic field is applied to such disk, the magnetization of the layer 103 just above the pit 105 is inverted by the initializing magnetic field. and an interfacial magnetic wall can be formed between an auxiliary layer 104. Then magneto-optical reproduction is performed as adding a reproduction magnetic field. At this time, the magneto-optical signal of the next pit 105 can be read out by applying the continuous irradiation of a laser power in a direction of recording track as inverting the magnetization of the layer 103 of the pit 105. Since a series of such operation are performed in a magnetically ultraresolution state, an information pit of high density can be reproduced as the magneto-optical signal.

IPC: H05K3/46
Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To minimize the drop in a power voltage caused by a resistance of a wiring line between a power source and ground. SOLUTION: Two vias 21 and 22 in a continuity with a ground wiring line 18 are guided out of a lower surface of a ceramic substrate 11. Joined to the lower surface of the ceramic substrate 11 is a heat sink 23 by brazing material 24 which, together with the heat sink 23, brings the vias 21 and 22 into continuity. Thereby an electric path 25 of the via 21, heat sink 23, brazing material 24 and via 22 are connected in parallel to the grounding wiring line 18.  The heat sink 23 and brazing material 24 are remarkably large in conduction sectional area when compared with conduction pattern of the grounding wiring line 18 within the ceramic substrate 11 (which resistance value is inversely proportional to the conductor sectional area), the heat sink 23 and brazing material 24 may be made of metals having low resistivities regardless of a sintering temperature of the ceramic substrate 11, whereby a wiring resistance between a power source and ground can be reduced.

Title: Heat storage mat for bathroom, and heat storage mat
Inventor: OMORI SHINJI
IPC: A47G27/02
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To increase the safeness of high-humidity bathroom environments by warming lower bathroom regions positively and suppressing cooling of lower bathroom regions by the coldness of bathroom floors. SOLUTION: This heat storage mat mainly for use on wet bathroom floors comprises a heating layer formed on a heat insulating layer 6, and a heat storage layer 15 formed on the heating layer. The heat storage layer 15 consists of a latent heat storage material of a higher heat insulating property and a larger heat storage capacity so as to emit a large amount of heat slowly to air or human bodies when contacting them. Even at an elevated temperature, the uppermost layer of the heat storage layer 15, which is lower in thermal conductivity, does not transfer much heat per unit time to human bodies. Heat transfers little by little from the lower layers to the upper layers as the uppermost layer experiences temperature drops. Since electrically disconnected, the heat storage mat involves no fear of leakage.  A generally hermetic air layer is interposed between the heat storage layer 15 and the heat insulating layer 6, preferably flush with the heating layer.

Title: Heat sensor
Inventor: FUJIMOTO SHINJI
IPC: A45D20/10
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To obtain a heat sensor functioning as a safety device preventing a user from continuously using an electric apparatus until a dangerous state, by joining a first metal of at least one selected from Fe, Ti, Ni, Nb and an alloy essentially consisting of these metals to a second metal of either Al or an alloy essentially consisting of Al. SOLUTION: A heat sensor 1 is formed by joining a first metal 10 of at least one selected from Fe, Ti, Ni, Nb and an alloy essentially consisting of any one of the metal elements to a second metal 20 of either Al or an alloy essentially consisting of Al. When the heat sensor 1 is heated, for instance, to a temperature range by a surrounding heat source, a fragile intermetallic compound is formed because of a counter diffusion of the metal elements of the first metal 10 and second metal 20. The fragile intermetallic compound is, e.g. FeAl2 or the like when the first metal 10 is Fe or essentially consists of Fe. If the fragile intermetallic compound is generated by a predetermined amount or more, the sensor automatically breaks, thereby shutting electric connection to the heat source.
