Patent JP-S6046770-A (JP)
Title: Power source
Inventor: YANASE ATSUSHI
IPC: H02M3/28
Filed: 1983-08-24
Abstract: PURPOSE:To suppress the fluctuation of the other output when one or more outputs are set to no load state by commonly using a transformer and a controller. CONSTITUTION:A base current is applied to a transistor 50 by the electromotive force induced from a winding 46A to 46B by a DC input, thereby switching the transistor. As a result, AC outputs generated at the windings 46C, 46D are produced as rectified outputs V01, V02, and applied to a controller 12. Here, when the output release input is applied to the control input terminal 100 from a controller 124, a transistor 94 is conducted, and a transistor 92 is interrupted. At this time, the output V01 is affected by the influence of the release of V02, the variation in the voltage occurs at the transient time, but the outputs generated at the output terminals 80A, 80B are stabilized by the operation of a photocoupler 72 and the transistor 50.

Title: Optical reception circuit
Inventor: YAGYU MIKITO
IPC: H03F3/08
Filed: 1988-06-24
Abstract: PURPOSE:To reduce the degradation of a maximum light reception level by monitoring and controlling the reverse bias voltage of an electrooptic transducer to suppress the fall of the reverse bias voltage of the electrooptic transducer in a light reception area higher than a gain switching point and the reduction of amplification factor accompanied with this fall. CONSTITUTION:A reverse bias voltage VAPD of an APD(avalanche photo diode) 2 is divided to VMON=R2.VAPD/(R1+R2) by a resistor (resistance value R1) 10 and a resistor (resistance value R2) 11, and VMON is inputted to an operational amplifier 12. In this case, the input of the operational amplifier 12 is made high-impedance and resistors 10 and 11 are set to high resistance for the purpose of preventing shunt of a photocurrent. The operational amplifier 12 compares the voltage VMON with a reference voltage Vref and outputs the signal (difference signal) indicating the difference between them to a high voltage generating circuit 9 in case of VMON<Vref. The high voltage generating circuit 9 is operated to reduce the difference indicated by this difference signal, and the output voltage is controlled to a prescribed voltage (which gives a usable minimum M of the amplification factor of the APD 2). In case of VMON>Vref, the high voltage generating circuit 9 is controlled by a gain control circuit 8.

The parts between 1 o'clock and 12 o'clock are not connected. A contact piece 5 is fixed to a clock pipe 4 penetrating through the center of the circumference of the plate 1. The piece 5 contacts with the point 2 at every one hour. The contact points in the 12 o'clock and 1 o'clock positions are connected respectively to the + side and - side of a power source. The voltage outputted from the piece 5 increases successively with the display of the hour hand and therefore a time-announcing sound is generated at every one hour by detecting said voltage.

Title: Manufacture of semiconductor device
Inventor: NAIKI TADAHACHI
IPC: H01L21/8244
Filed: 1990-06-14
Abstract: PURPOSE:To more effectively connect a diffused region to a source or drain diffused region by providing a step of previously ion implanting impurities to a part to be formed with the diffused region by diffusing the impurities in a gate electrode to the surface of a semiconductor substrate to a part to be formed with the diffused region before or after the formation of the electrode. CONSTITUTION:Since a gate electrode 9 is first patterned to completely cover a contact window 5, there is no fear of digging the surface of a semiconductor substrate 1 by dry etching for patterning at all. Accordingly, a fear of digging to separate between a source or drain diffused region and a diffused region formed under the electrode is reduced. Second, since the impurities are ion implanted previously before the formation of the diffused region by diffusing the impurities in the electrode 9 in the surface of the substrate 1, a connection between the diffused region 14 and the diffused region 12 can be more completely performed.

Abstract: PURPOSE:To pass through an input synchronizing signal only and to reject other noises, by providing a gate circuit which is open through the estimation of leading of an input synchronizing signal at the input of a PLL circuit, in a synchronizing shape circuit using PLL. CONSTITUTION:An input synchronizing signal (a) passes through a gate circuit 1 and becomes a rectangular wave c through being shaped at the 1st monostable multivibrator and is transmitted to a PLL circuit 9. An output synchronizing signal d based on the wave c is obtained from a delay circuit. An output e of a voltage controlled oscillator 4 is shaped to gate pulses f, g at the 2nd monostable multivibrator 6 and applied to the gate circuit 1 via an OR circuit 7, and since the-gate circuit 1 is set through the estimation of leading of the signal (a), noises mixed in other periods can be rejected. If the PLL circuit is unlocked, since the output of the phase comparator 3 is applied to the OR circuit via an integration circuit 8, the gate 1 is kept set independently of the output f of the 2nd monostable multivibrator 6.
