Title: Magnetic recorder
Inventor: SAKO MICHIYA
IPC: G11B5/09
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To improve the recording speed by increasing a voltage to be impressed on a magnetic head. SOLUTION: A transistor Q20 and a transistor Q21 are connected to transistors Q1, Q2 respectively using current mirror circuits constituted of transistors Q3, Q4 and transistors Q5, Q6 as the loads, so that the connecting directions of their biases and emitters are opposite. As the result, when the reverse bias voltage is impressed between the base-emitter of the transistors Q1, Q2, the transistors Q20, Q21 become in the states of forward bias, then the reverse bias voltage impressed between the base-emitter of the transistors Q1, Q2 is dropped to the forward bias voltage between the base-emitter of the transistors Q20, Q21.

Title: Semiconductor integrated circuit and its semiconductor device
Inventor: TAGUCHI MASAO
IPC: H01L29/72
Filed: 1987-12-24
Abstract: PURPOSE:To enable resistance matching by a characteristic resistance peculiar to a transmission-line and a termination resistance, and absorb reflected wave, by connecting the termination resistance almost equal to the characteristic resistance to the terminal part of an extremely low resistance wiring. CONSTITUTION:When a driving device T2, is ON, and a driving device T22 is OFF, the output voltage of a GMOS inverter is divided by the internal resistance of T21 50OMEGA and a termination resistance RL1=50OMEGA. The terminal resistance RL1=50 almost equal to a characteristic resistance (=50OMEGA) is connected, in this manner, to a terminal part of a signal line L1 for which an extremely low resistance wiring is used. Therefore the impedance matching of a transmission line is enabled by using the intrinsic characteristic resistance and the termination resistance RL1, and it becomes possible to absorb reflected wave. As a result, it becomes possible to transmit a high speed waveform having no distortion to a driving device of the next stage.

Title: Main body holding structure for wall paper gluing machine
Inventor: MIYAKI KANJI
IPC: B05C1/08
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To enable a main body part to be easily positioned and deposited on a pedestal by forming at least, one of the contact parts of an engaging part provided on the lower part of the main body part and a fitting part provided on the upper face part of the pedestal part in the shape of inclination, when designing both engaging part and fitting part to be mutually connected to each other with the assistance of an uneven structural profile. SOLUTION: An inclined part works in a direction in which the relative positional relationship between an engaging part and a fitting part is corrected by the reaction force of the inclined part with which both engaging part and fitting part come into contact, using the downward force of a main body part 1 generated when it comes down from the upper part of a pedestal part 9 by the weight of the part 1. This inclined part is provided at least, on either of the engaging part or the fitting part. That is, a downward facing protrusion part 20 is provided on the lower part of both ends in the longitudinal direction of the main body part 1. In addition, the front and rear faces of the protrusion part 20 has a tapered inclined face showing the narrowing of the width in a depthwise direction downward. Consequently, when depositing the main body part 1, it should be roughly positioned and set on the pedestal part 9. The rest is that the main body part 1 will be correctively inched by its own weight in response to a dropping action. Finally both main body part 1 and pedestal part 9 are set to a correct position and engaged with each other.

Title: Nonlinear optical element
Inventor: NAKAMURA SHIGERU
IPC: G02F1/35
Filed: 1993-12-28
Abstract: PURPOSE:To operate a nonlinear optical element which executes highs-peed light-light control by utilizing a band filling effect by absorption of control light and carrier sweeping by impression of a static electric field at a high speed by removing an unnecessary non-doped layer or p-n junction layer, thereby increasing its capacity and suppressing electric field screening at the time of carrier sweep. CONSTITUTION:A reverse bias voltage is held impressed between electrodes l and 9 and a static electricity is held impressed to a GaAs core layer 4. Control light pulses are absorbed by this GaAs core layer and carriers are formed, by which a change in refractive index is generated and the signal light propagating in an optical waveguide part is modulated in phase. The non-doped layers 4, 5 are removed exclusive of the part of 10mum width inclusive of the optical waveguide part. As a result, the element capacity is increased and the screening of the impressed static electric field at the time when the carriers are swept is suppressed. The high-speed operation is thus made possible.
