Title: Control device for hybrid vehicle
Inventor: FUJISAWA YUTAKA
IPC: B60L50/16
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To prevent shock from being generated when a power source is switched to an engine from a motor. SOLUTION: A control device for a hybrid vehicle drives a vehicle by changing over an engine 1 and a motor 3 or by the engine 1 and the motor 3 by coupling or releasing a clutch 2 intervened between the engine 1 and a transmission 4; the control device is provided with a generator 5 connected to the output shaft of the engine 1. When power change-over is applied to the engine 1 from the motor 3, the generator 5 absorbs engine torque. The clutch 2 is coupled when the rotating speed of the motor 3 agrees with that of the engine 1. The result constantly retains torque applied to the transmission 4 to suppress a shock in power change-over.

Abstract: PURPOSE:To make it unnecessary to test a device previously and to attain speedy recording and reproducing by detecting a reflected signal from a recording medium during recording to obtain a signal indicating a defective part. CONSTITUTION:Output light from a semiconductor laser generating device 10 is reflected by a mirror 6 through a condenser 9 and a beam splitter 7 and made incident to an objective lens 3. The laser output light from the device 10 is modulated by a laser light modulator 11. An output from a signal modulator 12 is converted into an laser light output, the laser light is reflected by an disc 1 and made incident to a photodetector 8 through the splitter 7 and the output of the photodetector 8 is inputted to a comparator 15 through a reproducing amplifier 14. On the other hand, a part of the output of the modulator 11 is inputted to the comparator 15 through a phase corrector 16, and if a group of the disc 1 has a defect, the defect is detected as the output variation of the comparator 15. Consequently, it is possible to detect the defect of the recording medium automatically and record the defect in another place during the recording, so that the recording time can be shortened by omitting labor for testing the device previously and the reliability of the recording itself can be improved.

Title: Capacitance design for mos transistor
Inventor: USUI SHINICHIROU
IPC: H01L29/78
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To design the optimizing of the capacitor structure by making the time taken for landing a channel center float to the ground level after the start of precharge to the gate of a transistor, equal to the time taken for starting the voltage rising operation of a source or drain diffused layer from the start of the precharge. SOLUTION: The time t1 taken for setting a channel center float to the ground level after the start of precharge to the gate of a transistor is made equal to the time t2 taken for starting the voltage rising operation of a source of drain diffused layer from the start of the precharge to thereby start the voltage rising operation of the diffused layer after landing the float to the ground level. Thus, the channel length L is obtained to be an optimum value from L= t2/(0.55.K1.K2)}<1/2> , where K1 and K2 are capacitance per unit area between the gate and channel and channel resistivity of the transistor. The channel width W of the capacitor is obtained from W=C/K1.L.

IPC: H03K3/53
Filed: 1990-06-25
Abstract: PURPOSE:To generate a rectangular voltage by eliminating unbalance at the time of charging pulse lines to enhance the energy transmission efficiency. CONSTITUTION:Pulse lines 5, 6 are charged through the application of a switch 10. A reactor 14 is immediately saturated and supplied a sufficiently small inductance in comparison with that of a coil 3, both the pulse lines 5, 6 are charged up almost under the same condition and no unbalance in the charging is caused. After the end of charging, a switch 8 is closed to invert the voltage of the pulse line 6, then a switch 12 is closed to apply a voltage to a load 13. The inductance of the reactor is rapidly increased because the voltage applied to the reactor 14 is reverse to that at the time of charging and a rectangular wave is generated.

IPC: B22D11/04
Filed: 1989-06-29
Abstract: PURPOSE:To accurately predict break-out from temp. pattern by detecting the temp. pattern with plural pieces of thermocouples embedded in each face of a horizontal mold. CONSTITUTION:At first, in the case of twin directional drawing type horizontal casting where molten steel 2 is cast by dividing the steel 2 into right and left sides at center part of the mold, the temp. pattern shown with the thermocouples 11 embedded in one face of the horizontal 1 has the temp. distribution having the peak temp. in the broken point because a breaking point of solidified shell is generated at near center part of the mold and there is the peak temp. at the breaking point. However, actually, in process of variation of the temp. distribution just before the break-out occurs, the temp. at center part of the mold is rapidly lowered and the temp. distribution pattern having two peaks is developed and position where the temp. lowers, is gradually widened toward both cast slab strands 4 and at last, the temp. distribution pattern where the temp. measured at the point being mostly far from the center part comes to high temp. is developed and the break-out occurs. Therefore, by quickly detecting this initial phenomenon, the break-out can be predicted.
