Title: Semiconductor device
Inventor: MATSUMURA MASAMI
IPC: H01L29/74
Filed: 1983-04-12
Abstract: PURPOSE:To improve the performance of the titled device by improving the critical rate of rise of off-state voltage and critical peak off-state voltage of a thyristor without increasing the gate trigger current by a method wherein the depth of an N type emitter layer is formed small in tge periphery and large at the other part. CONSTITUTION:Said device including a thyristor chip is composed of four layers of an N<+> emitter layer 1, a P-base layer 2, an N-base layer 3, and a P-emitter layer 4. The depth x2 in the periphery of the emitter layer 1 of this device is formed smaller than the depth x1 of the other part. Even when the spacial charge layer of the P-N junction 10 expands, the reach of charges to the emitter layer 1 is prevented, thus improving the critical rate of rise of off-state voltage and critical peak off-state voltage characteristic of the thyristor, resulting in the improvement of the performance of said device.

Title: Flatness measuring method and device therefor
Inventor: OTOTAKE TARO
IPC: G01B21/30
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To accurately measure flatness by subtracting deflection due to the dead weight of a platelike object computed or measured from the distorted state of the platelike object held with a holder. SOLUTION: In measurement of flatness, at first the distorted state of the upper face of a mask 203 is measured by a known method. Deflection 201 is deflection due to the dead weight of the mask when the mask is held with a holder of three-point support only by frictional force without addition of external force. The distorted state 203 of the upper face of the mask is the sum of the deflection 201 and flatness 202, and the deflection 201 due to the dead weight of the mask can be measured by a known measuring method. Because the shape of the mask is a simple platlike shape, the deflection 201 due to the dead weight of the mask can be correctly obtained by theoretical computation such as a finite element method. The flatness 202 of the mask to be finally obtained is obtained by subtracting the deflection 201 due to the dead weight from the measured value 203 of the distorted state.

Title: Electrophotographic recording device
Inventor: ARAI SEIJI
IPC: G03G15/06
Filed: 1989-03-16
Abstract: PURPOSE:To prevent generation of fogging by positioning a space between the two recording paper carried continuously at a transferring position and changing a voltage value of a developing bias to a specified value during the period while a part in a photosensitive body drum which is passed through the transferring position is passed through a developing position. CONSTITUTION:When the space formed between the two recording paper 14 which are continuously transferred is positioned in the transferring position of a transferring means 5, that is, when the part of the photosensitive body drum 1 which has passed the transferring position when the photosensitive body drum 1 was in a state to be electrified by the transferring means 5, that is when developing the electrified part by the transferring means 5, the voltage value of the developing bias is changed to a specified voltage value. Therefore, if the specified voltage value is set to be an appropriate value, potential difference between the electrifying potential and developing bias potential of the photosensitive body drum 1 is retained to be a specified potential difference. Thus an image of high quality can be obtained without generating 'fogging' in the recorded image.

CONSTITUTION:On the surface of a rotation Y cut LiNbO3 substrate 1, a two- port Love wave type surface wave resonator 6 and a one-port Love wave type surface resonator 7 are constituted by an Au electrode and both are connected in parallel. A two-port resonator 6 is composed of an input IDT2 and an output IDT3 and a reflector 4 at both sides and arranged so that the phase shift between input output terminals can be 180 deg.. A one-port resonator 7 is connected so that two IDTs can be a reverse phase, the wave excited by these IDTs is resonated by an antisymmetrical mode, and the serial connection is executed so that a parallel capacity Co can be made smaller (Co is reduced to 1/4 by the two-equally-divided serial connection of the IDT). Thus, the band pass filter, which is small in an insertion loss and excellent in a passband characteristic at the wide band at the high frequency area, is obtained.

Abstract: PURPOSE:To exactly measure titled thrust load, by converting the thrust load, being loaded on the measuring bearing constituted so as to receive only the thrust load, into an electric signal using the load detecting element. CONSTITUTION:When the load is given to the roll 1 of the rolling mill, the radial load is borne by the cylindrical roller bearing 3, but the thrust load is borne by a couple of the right and the left conical roller bearings 4.
