Title: Output controller for laser diode
Inventor: MICHIGUCHI YOSHIHIRO
IPC: H01S5/0683
Filed: 1987-06-12
Abstract: PURPOSE:To always output a constant modulation light by controlling temperature which affects an output and further so controlling as to compensate the frequency dependency of an impedance used to monitor the output. CONSTITUTION:Temperature information of a thermistor 103 is obtained to operate a switching element 10, a current flows to a cooler 104 to cool the interior of the element 1. If the setting level of the element 10 is set to a constant by this control, the element 1 can be always maintained constant temperature. Since the impedance is varied according to its frequency, if an impedance 5 is varied to an impedance amount stored in advance in a memory cell 11 by frequency information from a frequency setter 9, the impedance 5 becomes constant regardless of its frequency, and the modulation output of a laser diode 101 can be controlled constantly irrespective of a modulation frequency. Thus, a light modulation output which is constant for a long period can be obtained.

Title: Current mirror circuit
Inventor: MATSUYAMA EIICHI
IPC: H03F3/34
Filed: 1985-07-01
Abstract: PURPOSE:To decrease much the difference between a reference current and an output current by inserting an operational amplifier between the 1st transistor (TR) and the 2nd TR and impressing a voltage to the control electrode of the 2nd TR by the operational amplifier. CONSTITUTION:Since an input terminal + of the operational amplifier 4 is at a high impedance, almost no reference current I1 flows to the input terminal + of the operational amplifier 4, and then the reference current I1 is the sum of a base current IB and a collector current IC of the 1st TR 2, that is, IB+IC. On the other hand, a voltage equal to a base voltage of the 1st TR 2 is impressed to a base 3b of the 2nd TR 3 by the operational amplifier 4, then an output current I2 becomes a current equal to the collector current IC of the 1st TR 2. Thus, the difference between the reference current and the output current is IB to obtain a current mirror circuit with high accuracy.

Title: Control device for induction machine
Inventor: NAGASE HIROSHI
IPC: H02P21/00
Filed: 1979-11-12
Abstract: PURPOSE:To enable stable operation of an induction machine without affect of a secondary resistance change by detecting the variation of a secondary resistance value, adding said value to the set value, and calculating the actual secondary resistance value. CONSTITUTION:Since the actual voltage is increased higher than the set value when the secondary resistance value is increased higher than the set value, the voltage is detected by a detector 22, and the deviation between the detected value and the set value by the multiplier 20 is obtained by a subtractor 23. Since the gate 35 is turned on in high speed range, a voltage control circuit 26 will produce a signal responsive to the output signal of the subtractor 23, thereby obtaining the variation corresponding to the reference secondary resistance value set by a secondary resistor 27. Then, the secondary resistance value is added to the variation by the adder 28, thereby obtaining the signal proportional to the actual secondary resistance value. On the other hand, if the secondary resistance is decreased, since the set value becomes lower than the detected value, a signal proportional to the actual secondary resistance value is fed from the adder 28 similarly.

Abstract: PURPOSE:To cook a foodstuff at the optimum temp. by a method wherein a cooking sphere is filled with the mixed vapor of steam and air and the volume ratio of steam occupying in the mixed vapor is controlled to regulate the temp. in the cooking sphere at an arbitrary uniform temp. CONSTITUTION:A foodstuff 12 in put on a tray 13 in the cooking sphere 2 of a cooking chamber 1A and a necessary amount of water in previously supplied to a stream supply means 3. When cooking is started by turning ON a start button after temp. and heating time are set, steam 17 is supplied by the means 3 and at the initial stage the steam 17 supplied into the lower space 16 rises up because the steam is lighter than air 18 and constitutes mixed vapor with the air 18. The temp. in the sphere 2 is determined by the mixed vapor 19 of which temp. depends on the volume ratio occupied by the steam 17 and when the temp. of the vapor 19 reaches the temp. set by a detecting temp. sensor 401, the supply of the steam 17 is stopped. When the temp. of the foodstuff 12 is still in lower temp., the supply operation of the steam 17 is repeatedly carried out to raise the temp. of the foodstuff 12 and its temp. rise results in the reduction of steam consumption and when a set heating time has come round, a steam heater is OFF and cooking is finished.

Title: Connector unit for high density integrated circuit chip
Inventor: JIYAWATSUDO FUAIKU ADAMU
IPC: H01R12/71
Filed: 1981-09-18
Abstract: A single level packaging arrangement and connector for large or very large scale integrated circuit chips is disclosed. This arrangement utilizes dual function optical transducers and fiber optic cables as the transmission medium by which most, if not all, chip I/O communication is effected. The top portion of the connector acts as a conductive collar which serves as both a heat sink and a shield against stray external signals. A chip site is formed in the top portion of the connector and the chip removably lodged therein. The top portion of the connector also includes connector pads which are utilized to make solderless connection to deformable chip pads and to dual purpose optical transducers. Thermal grease, which is forced into and fills site cavities provided for that purpose, assists in conducting heat from within the connector to thereby enhance the heat dissipation characteristics of the chip site. The chip itself is retained in the site by the use of wedges and retaining strips secured to the connector at appropriate locations therein. The bottom portion of the connector is provided with a first group of holes that house the optical transducers in operative alignment with the bottoms of predetermined ones of the site connector pins. A second group of holes in the bottom portion includes the optical cables that couple the chip's I/O pads to selected circuits and/or devices. The top and bottom connector portions are joined together by suitable means.

IPC: H02P9/30
Filed: 1979-11-14
Abstract: PURPOSE:To increase the operating limit of a synchronizer by forming a synchronizer field current control system capable of switching with a synchronizer terminal voltage constant control system. CONSTITUTION:A deviation signal between the synchronizer terminal voltage VG detected by an instrument transformer 4 and a set value Vrefl is applied through an automatic pulse phase unit 16 to a thyristor 11 in normal state. If this automatic system malfunctions, automatic-manual switch 17 is switched, and a voltage and current control switch 24 is energized. In this state, a voltage signal adder circuit 23 applies the deviation signal between the terminal voltage VG and the set value through an automatic pulse phase unit 21 to a thyristor 11. If an operator selects a control switch, the switch 24 is deenergized, and the field current constant control system is switched by the current signal adder circuit 9. Thus, the automatic controlling range can be extended.
