Title: Semiconductor device
Inventor: KODAMA HIROKI
IPC: H01L23/36
Filed: 1994-05-24
Abstract: PURPOSE:To reduce thermal expansion in a plane direction and improve heat conduction from a mounting face to the rear face of a board for mounting a semiconductor chip, by using a composite board made of base material with low thermal conductivity including a high conductivity material elongated vertically. CONSTITUTION:In a semiconductor device, a semiconductor chip 5 is die-bonded on a board 1. The board l comprises a base 1a made of material like Invar with low thermal expansion, and a thermally conductive member 1b made of copper embedded vertically to a face part for mounting a semiconductor chip 5. Then, thermal expansion in a plane direction becomes low, and thermal conductivity enough to radiate the heat from the semiconductor chip 5 can be ensured. As a result, heat radiation of the semiconductor chip 51 is improved with no fear of a decrease in reliability caused by a defect in connection of the semiconductor chip 5.

Title: Power transistor
Inventor: MIYASAKA TADASHI
IPC: H01L29/72
Filed: 1987-05-07
Abstract: PURPOSE:To render the balance of an emitter current more adequate so as to improve the breakdown strength and also decrease the loss and the heat induced by a current balance resistive section by a method wherein a gap is provided between a base wiring and a base electrode adjacent to the wire connecting a connecting section of a base wiring connected with a base terminal to a connecting section of an emitter wiring connected with an emitter terminal. CONSTITUTION:A cut section 5 is provided at the base of a base electrode 11 the most adjacent to a wire connecting a bonding section 3 of a base wiring with a bonding section 4 of an emitter wiring. Therefore, a base current 7 flows through a base section 8 of a silicon substrate 10 and is restricted by a base sheet resistor 9 connected with a base in series, so that the convergence of the base current into an emitter electrode positioned at the central part of the substrate is alleviated. Thereby, the balance of a current is rendered adequate and as a base current is smaller than an emitter current, the loss and the heat are made smaller as compared with those induced by the resistor through which a restricted emitter current flows and an additional process is rendered unnecessary, and thus a breakdown strength is improved.

Title: Automatic frequency control alarm circuit
Inventor: TAKENAKA NOBUO
IPC: G08B21/00
Filed: 1979-08-31
Abstract: PURPOSE:To detect a fluctuation period even if this period is short, by outputting alarm when the amplitude of the signal, which is caused to pass through the AC amplifier which amplifies the signal obtained by converting frequency fluctuation to voltage change, exceeds allowable fluctuation. CONSTITUTION:In automatic frequency control circuit 13, the signal converted to an AC voltage passes through AC amplifier 9 and has a part connected to DC amplifier 16 in AC. A reference DC voltage corresponding to the middle point of the hysteresis of Schmitt trigger circuit 18 is superposed onto the signal in amplifier 16, and the obtained signal is applied to circuit 18. When the signal exceeds the threshold voltage of circuit 18, the output of circuit 18 is inverted. Retriggerrable monostable multivibrator 19 is started by this inversion signal, and the output which has the width expanded is obtained as an alarm signal at terminal 20.

Title: Stepping motor control circuit
Inventor: TAKEDA KUNIYOSHI
IPC: H02P8/28
Filed: 1978-09-11
Abstract: PURPOSE:To perform application of damping force to a stepping motor without spending wasteful excitation current, a timer circuit is provided for applying a forced excitation signal to a given phase of the motor after a specific period from the motor stop signal application. CONSTITUTION:Applying LOW level stop signal to STOP terminal resets the delayed flip-flop 2 causing the output Q1 to be LOW, and sets the NOR circuits 4, 10, 12 to OFF. Because the output of the inverter 24 and inversion signal of the delayed  flip- flop 19 outpout Q are HIGH, the AND circuits 22, 23 are OFF. This causes  pulses EM1 and EM3 to be forced to become HIGH and excites for a motor to be stopped. (EM2 and EM4 remains LOW.) After a given time determined by the  period of clock pulses entering the clock terminal phi, the timer circuit 17 emits LOW  signal to cause EM1, EM3 to be LOW, generating non-excitation condition.
