Title: Igbt with built-in circuit and power conversion device using the same
Inventor: KONO YASUHIKO
IPC: H01L27/04
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of malfunctions of a circuit region due to a lead of a Hall current by a method, wherein earth electrodes are provided on the base layer of a lateral MOSFET on the circuit region and the earth electrodes are connected with the emitter electrode of an IGBT. SOLUTION: This is an example of an insulated-gate bipolar transistor(IGBT) having a built-in circuit. Grounding layers 130 are provided on a lateral MOSFET on a circuit region 151, and these grounding layers 130 are connected with an emitter electrode 110 of the IGBT via grounding electrodes 113. By providing the grounding layers 130, a Hall current, which flows from a collector layer 117 into a base layer 132, is not made to flow through a source follower circuit. That is, the Hall current is not made to flow through source layers 131 and is made to discharged from the grounding layers 130 to the electrode 110. Accordingly, a current, which is made to flow through the source follower circuit, and the Hall current can be separated from each other.  As a result, the fluctuations of a voltage, which is generated in a source follower resistor 140 are inhibited, and malfunctions of the circuit region 151 can be prevented from being generated.

Abstract: PROBLEM TO BE SOLVED: To realize a multilayer wiring board with a built-in resistor whose resistance is more improved in uniformity than usual and enhanced in accuracy by a method wherein an insulator nearly as thick as a resistor is provided around the resistor, and an electrode conductor is provided above the resistor and the insulator. SOLUTION: A resistor ink thick film is formed on a board 11 through a silk printing method for the formation of a resistor 12, and an insulator 13 formed of paste or sheet-like insulator material is provided nearly as thick as the resistor 12 around the resistor 12.

Title: Noncontact type data carrier system
Inventor: MIURA TORU
IPC: G06K17/00
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To reduce the development cost by adapting a data carrier to more than one purpose of use without depending upon the contents of an internal memory of the data carrier. SOLUTION: In an EEROM 18 as part of the memory of the data carrier 10, an area where conditions of contents to be sent from the data carrier to a reader writer 1 for the 1st time are set is previously secured, and initial data on the address specification of the memory stored with the data to be sent and the amount of the data to be sent are set. The data carrier 10 when recognizing a communicable state by receiving a signal from the reader writer 1 reads the data out of the area where the memory is set and then reads a specific amount of data out of the specified address as starting transmit data to the reader writer 1.  The condition setting of the data contents that the data carrier 10 sends for the 1st time makes it possible to rewrite the data in the specific area by using the reader writer 1, and consequently, this system is adaptive to a variety of uses with the same dedicated IC.

Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To realize an extremely safe electronic delay electric detonator which does not have a misfiring region even if a variety of methods of using is employed and an impact value from outside becomes high. SOLUTION: Working range of an electronic timer section is expanded by enhancing shock resistant property of the electronic timer section so as to be substantially overlapped with a lower limit of a range of detonation of the detonator by influence.

A second oscillating period of a piezoelectric transducer having an oscillating standard different from that of the quartz-crystal oscillator 21 can be calibrated at a high precision by using a standard of a first oscillating period based on a fixed frequency of the quartz-crystal transducer 21.  A portion 87 between an igniter layer 82 and an initiator layer 83 of a detonator is provided with a space having a length of 4 to 14mm to enhance detonating performance, and the range of detonation by influence is expanded so as to be substantially overlapped with an upper limit of the working range of the electronic timer.

Title: Battery-driven computer
Inventor: MAKITA MASARU
IPC: G06F1/30
Filed: 1994-12-21
Abstract: PURPOSE: To surely continue interrupted processing by inhibiting restart when power capacity is judged a little at the time of restart after power save processing. CONSTITUTION: When a suspend/resume button 3 is depressed during the execution of 0V suspend in the state of supplying power at a certain degree for detecting the depression of the suspend/resume buttom 3 at a main body 1 of a computer from a battery at least, a resume SMI occurs to discriminate the presence/absence of power enough for starting the resume. When it is discriminated there is no power enough for starting the resume, the 0V suspend is continued. Thus, since power capacity is checked in the case of restart after a change into a power saving mode, trouble such as performing useless starting operation or the erasure of data under processing although there is no power enough for restart can be prevented.
