Title: Thin-film transistor
Inventor: NOMURA KOJI
IPC: H01L29/78
Filed: 1984-07-30
Abstract: PURPOSE:To prevent the enlargement of damage caused by a large current by dividing a channel region of a semiconductor layer at least into two parts with which source and drain electrodes are connected. CONSTITUTION:In a thin-film transistor, a channel region 19 of a semiconductor layer is divided into plural parts and these are connected to a drain electrode 20 and a source electrode 21. By such constitution, if a large current flows in the channel region 19 as an insulation damage occurs for the thin-film elements during operation, for example, even if a discharge occurs at the part 22, the damage does not reach the adjacent semiconductor layer because the semiconductor layer is divided. Accordingly, there is no possibility that a damage reaches the whole semiconductor, and the reliability can be exceedingly improved.

Title: Electrochromic display device
Inventor: YOSHIIKE NOBUYUKI
IPC: C09K9/00
Filed: 1978-12-20
Abstract: PURPOSE: To achieve the longer life of the display device and enhance reliability by letting the iron compound insoluble in electrolyte as a reference electrode used for defining the potential of display electrodes.  
     CONSTITUTION: Iron compound which is insoluble in the electrolyte 8 of the electrochromic display device (ECD), such as Berlin acid iron or its derivative as a material for a reference electrode 5 as well as current collecting material (carbon powder, etc.), binder (polyethylene powder, etc.) and Pt wires (lead parts) are buried and thermo-molded to make the electrode 5. While a fixed square wave is being applied to the electrode 5 from an external circuit, current is flowed to the counter electrode 4, whereby the potentials of the display electrodes 2 of the ECD are well controlled and yet the deposition of the deposits on the electrodes 2 and the staining these are obviated. Hence, the ECD is made longer in life.

Title: Method for measuring sample by self-detection-type cantilever and scanning-type probe microscope device
Inventor: SHIRAKAWABE YOSHIHARU
IPC: G01B21/30
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To take out only a physical distortion signal as a signal when approaching by providing a radiation part on the surface of a cantilever body and reducing the heat exchange effect operating between a sample and a probe. SOLUTION: A radiation part 11 is provided at a lever body 3. For example, when a number of fine projecting parts 10 are provided between a probe 4 and distortion sensors 5 and 6, the surface area of the lever body 3 increases by providing the fine projecting parts 10, heat radiation at this place is accelerated, thus suppressing the heat transfer between the probe 4 and the distortion sensors 5 and 6. As a result, when the probe 4 approaches the sample, the output of signal components from the distortion sensor elements 5 and 6 due to heat detection can be effectively prevented.  Therefore, by using a cantilever 1, a signal component being generated by the physical distortion of the lever body 3 can be taken out from the distortion sensors 5 and 6 without being greatly affected by the influence or the like caused by the collapse of the temperature balance state in an approach operation.

IPC: G06F5/01
Filed: 1990-06-19
Abstract: PURPOSE:To shorten a segmentation shifting processing time and to improve a signal processing speed by providing this segmentation shifter with a 2nd masking circuit for aligning a required bit number part with one logical value and a bidirectional shifter for shifting the output of the 2nd masking circuit in a required direction by the required number of bits.

Although this segmentation shifter is used for segmenting a required intermediate bit part 37 in data and shifting the part 37 into a required position, the shifter can be used also for segmenting a required bit part from the MSB side or the LSB side and shifting the segmented part to a required position. In any case, shifting operation can be attained only by one operation. Consequently, the segmentation shifting processing time can be shortened and the signal processing speed can be improved.

Title: Fluid couping device
Inventor: HIKITA HAJIME
IPC: F04B49/08
Filed: 1982-09-14
Abstract: PURPOSE:To relieve fluctuation in the number of revolution of a water pump and to reduce power consumption of a motor, by transmitting discharge pressure of the water pump through an accumulator to a fluid coupling. CONSTITUTION:When the amount of water to be used in a load 15 is increased (or decreased) from a normal equilibrium state, discharge pressure of a water pump P falls (or rises). This pressure is transmitted through a medium 16a in an accumulator 16 to a spool head 17c of a control valve 17. A spool 17b is biased by a push spring 17d in a right (or left) direction to increase (or decrease) hydraulic pressure of oil leaving a hydraulic oil port 17f and entering a faluid coupling 11. As a result, slip rate of the fluid coupling 11 is decreased (or increased) to increase (or decrease) the number of revolution of the water pump P, thus returning discharge pressure of the water pump P to an original equilibrium state. Even when there occurs rapid and frequent increase or decrease in the amount of water to be used, pressure of the pump is once induced in the accumlator 16 having large capacity, thereby transmitting gentle fluctuation in the pressure to the flud coupling 11.

Abstract: PROBLEM TO BE SOLVED: To store the data under the multivalued state of three values or more into one memory cell, by changing the time for performing writing into the memory cell stepwise in correspondence with the data inputted into a device. SOLUTION: When writing is performed in a memory cell array 7, a signal DIN including a writing instruction command address and data is inputted into a mode decoding logic circuit 5 in synchronization with a clock CLK. When the signal is recognized as the instruction code, conversion for application to 2-bit/cell method is performed for the input data with a data conversion circuit 10, and thereafter the writing into the memory cell specified for a high- voltage switching circuit/decoder 1 and a Y gate 8 is performed. In this way, the input data undergoes the conversion suitable for 2-bit/cell method in the data conversion circuit 10. In each cell, the writing time is changed stepwise in correspondence with the data of 2 bits. Therefore, the storage of the data under the multivalued state of three or more values can be performed as in the 2-bit/cell method.

Abstract: PURPOSE:To enable a low-frequency magnetic field to be shielded by a method wherein a planar conductor surface is arranged in the orthogonal direction to the magnetic field direction to be shielded in a plane vertical to the magnetic direction for generating an eddy current in the planar conductor. CONSTITUTION:A cylinder 1 formed of a conductor plate e.g. copper, aluminum etc., having disklike covers 1a, 1b to constitute the title hollow shielding body. Besides, a rack 3 for mounting an objective element shielded against magnetism is provided on the cover 1b of the cylindrical body 1 to be rotatably held in the floating state over the floor to be rotatably driven by a rotary driving device and a driving belt 4. When the magnetic flux intrudes into the cylindrical body 1 in the vertical direction to the cover 1b, an eddy current is generated in the cover 1b. On the other hand, the eddy current is eccentrically generated by the rotation of the cylindrical body 1 so as to generate an interfering magnetic flux with the penetrating magnetic flux by the eddy current. Through these procedures, the penetrating magnetic flux divertedly advances to avoid the cover 1b for passing over the surface of the cylindrical body 1.
