Title: Manufacture of semiconductor laser
Inventor: TOMINAGA KOJI
IPC: H01S5/00
Filed: 1992-05-20
Abstract: PURPOSE:To manufacture a semiconductor laser of high output structure wherein the thickness of an active layer changes in the resonator length direction, by using an MOCVD method. CONSTITUTION:When a ridge type multilayered crystal film turning to an optical waveguide is formed on an InP substrate 1 by using an MOCVD method, a pair of masks 2, 2 for selective growth are formed on both sides of a region where the multi-layered polycrystalline film is formed on the InP substrate 1. The width of the mask 2 is changed in the resonator length direction. Narrow width parts 22 are formed in the vicinity of the resonator end surface. Wide width parts 21 are formed in the central part of the resonator. Thereby a thin active layer is grown on the narrow width part 22, and a thick active layer is grown on the wide width part 21.

Title: Voltage optical sensor
Inventor: TOJO MASAAKI
IPC: G01R15/24
Filed: 1990-05-16
Abstract: PURPOSE:To miniaturize a device and to perform measurement with high sensitivity by joining electro-optical crystal in which a reflecting mirror is provided at a plane perpendicular to a Z-axis with a polarizing beam splitter via a wavelength plate, and providing a cubic mirror on a plane opposite to the splitter. CONSTITUTION:Light emitted from an optical fiber 12a is converted into parallel rays 13 with a rod lens 7a passing a precision capillary 9a. Only the specific linearly polarized light of a light beam 13 is reflected on the polarizing beam splitter 1. The linearly polarized light 14, after being converted into elliptically polarized light by a 1/8-wave plates 2, is made incident on lithium niobate crystal 3, and is reflected on a reflecting plate 4. Reflected light 15 passes the crystal 3, and passes the wave plate 2, then, is changed to circularly polarized light. Only the half quantity of the circularly polarized light passes the splitter 1, and is reflected on the cubic mirror 6. Reflected light 16 is converged on the rod lens 7b, and after being inputted to the precision capillary 9b, is inputted to an optical fiber 12a in a ferrule 11b. In such a way, the actual length of the crystal 3 can be reduced since both forward and backward paths can be used as an optical path, and no reduction of rigidity occurs even when width is reduced and sensitivity is increased.

Filed: 1992-05-20
Abstract: PURPOSE: To provide an improved thermoelectric device which can be fabricated using a method for fabricating a microcircuit by constituting and arranging the thermoelectric device with respect to a thermocouple such that heat is transmitted from a metal layer to a first contact and from a second contact to a basic body. CONSTITUTION: When a blackened compound 22 is heated with infrared rays from a heat source 40, the layer 22 transmits heat to a heat collector 20 but a thick oxide part 26 prevents heat in an aluminum layer 20 from intruding into an oxide layer 16. Heat is transmitted to a heat transmitting place 24 on a thin oxide part 36 and collected onto a hot contact 32 through the thin oxide part 36. The heat is transmitted through a thermopile to a cold contact 34 and sucked through the thin part 38 of a first oxide layer 18 into a basic body 10. Consequently, the cold contact 34 has same temperature as the basic body 10 and a voltage difference appears between the hot contact 32 and the cold contact 34 based on the temperature difference.  A plurality of thermocouples amplify the voltage difference thus realizing a semiconductor thermoelectric device producing a significantly high output voltage.

Title: Bootstrap type inverter circuit
Inventor: MIWATA KAZUO
IPC: H03K17/06
Filed: 1984-06-22
Abstract: PURPOSE:To stabilize the operation of a bootstrap type inverter circuit without requiring any improvement in the dielectric strength property on process, by suppressing the potential rise of a contact where the voltage becomes higher than the supply voltage of the inverter circuit. CONSTITUTION:Since IN is high in level and an MOS transistor (TR) M2 is turned on, the electric potential V3 of an output signal OUT goes to VL1 which is determined by the gm ratio of MOSTRs M1 and M2 and is low in level. Moreover, the electric potential of a node (5) becomes a constant potential V5 which is determined by the TR size ratio of MOSTRs M5 and M6. Therefore, the source potential V4 of an MOSTRM4 becomes V4=V5-VT4 by using the V5 as a gate voltage. The VT4 is the threshold voltage of the MOSTRM4. Namely, the initial potential of the source voltage V4 can be set optionally. Therefore, the electric potential V4(t=t6) of a node (4) when the IN becomes low at a time t5 and the V3 rises to the electric potential of a voltage VD at the next time t6, finally goes to V4(t=t6)=V5-VT4+(V5-VT4-VL1). CB/(CA+CB). In such a way, the electric potential V4 can be changed optionally through the electric potential V5 and not through the electric potential VD. Accordingly, stable operations of a bootstrap type inverter can be secured even under a high voltage.

Title: Preventing method for camber generating in hot rolling process
Inventor: ASAI HITOSHI
IPC: B21B37/68
Filed: 1980-09-17
Abstract: PURPOSE: To surely prevent a camber generating in a rolled strip, by detecting the displacement  of an edge of the rolled strip during the rolling process, by adjusting the rolling reduction, by correcting the traveling direction of the rolled strip, and by forcibly correcting the position of the displaced edge to a correct position.  
     CONSTITUTION: The breadth of a rolled strip (a) carried in is detected by a breadth meter 2 before being fed into a finishing mill F, and a command signal corresponding to the detected  breadth is sent from a controller 4 to a motor M 1 . The guiding width of a side guide 11 is set to  the breadth of the rolled strip (a) by the motor M 1  driven by the said command signal, and thereby, the strip (a) is fed into the mill F. The displacement of the strip (a) is detected by an edge  position detector 3 on the run-out side of the mill F; the controller 4 compares this detected displacement of the strip edge with a preset reference value, and sends a feedback command corresponding to the positional deviation obtained by the said comparison, to a motor M 2  and a rolling  reduction adjuster 5. The motor M 2  then forcibly adjusts the location of the strip (a) being guided  by the guide 11, and feeds it into the mill F. At the same time, the rolling reduction adjuster 5 regulates an unbalanced condition between the rolling reductions on the left and right sides, and corrects the traveling direction of the strip (a).
