Abstract: PURPOSE:To prevent storage of carrier as a level pair and to perform an ultrahigh speed operation by providing carrier generating means for generating carrier as first level pair, and carrier eliminating means for eliminating carrier transited from the first level pair to a second level pair by inductively irradiating. CONSTITUTION:When a superlattice layer 12 is irradiated with a signal light having a wavelength lambda2 from a signal light laser light source 20, it is partly absorbed to excite electrons and holes to a level pair of energy E2 of the layer 12. The remainder is transmitted and received by a photodetector 24. A reception signal of the photodetector 24 becomes a predetermined intensity responsive to the intensity of the signal light. Here, when the layer 12 is irradiated with a control light of pulselike high output from a control light laser light source 22, the electrons and the holes are excited to the level pair of the energy E2, and the electrons and the holes existing at the level pair of the energy E2 are temporarily increased. However, the electrons and the holes excited to the level pair of the energy E2 are transited to the level pair of energy E1 by an alleviation, and hence the absorption ratio of the layer 12 is increased, and the reception signal of the photodetector 24 is recovered.

Title: Traveling speed controller
Inventor: NAKAMURA HARUHIKO
IPC: H02P29/00
Filed: 1993-09-03
Abstract: PURPOSE:To improve the distance accuracy of a traveling equipment regardless of undershoot or overshoot by converting the relation between speed and time in an adjustable-speed section into the relation between speed and theoretical position and by comparing measured position with theoretical position. CONSTITUTION:A speed arithmetic unit 2 receives a traveling distance from a running controller 3, reads data from a storage 1 and prepares a speed pattern of speed to time relations. The speed arithmetic unit 2 performs arithmetic operation in such a manner that the speed to time relations in acceleration section and deceleration section prepare a relation along a sine curve and then covert the speed to time relation into the speed to position relation. The running controller 3 drives a running drive motor 5 in accordance with the speed pattern from the speed arithmetic unit 2. In consequence, the speed output value is retained constant until the measured position catches up with the theoretical positions. Therefore, a running carriage can run in a pattern close to a speed pattern determined by the arithmetic operation regardless of the followability of the motor 5.

IPC: G09G3/36
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To easily correct a phenomenon of blue-tinged display color caused when an input video signal is decreased in the level. SOLUTION: This color liquid crystal display device attenuates a B-signal gain by controlling a gain control circuit 21 as a luminance (R+G+B) signal is decreasing in the level. However, the attenuation degree is defined as a maximum in the case of achromatic color, and is controlled to decrease from the case of the achromatic color as color light is increased in chroma. Thus, it is possible to correct a phenomenon of blue-tinged display color in a liquid crystal panel 24 caused when an input video signal is decreased in the level.

Abstract: PURPOSE:To eliminate micro defect from a fine pattern formed on a thin film or a cleaned surface which resist is exfoliated by cleaning the surface on a substrate from which photoresist is exfoliated or the surface for forming a thin film by the use of a specified ultrapure water. CONSTITUTION:pH of waste water is controlled in the range of 5.4-6.8 and polyaluminate chloride of 75-100ppm is added to the waste water in order to aggregate and precipitate main impurities.

Abstract: PURPOSE:To attain the detailed discrimination according to the bending of a stroke even after approximation of the stroke owing to a flexion point, by extracting the flexing points of different types of a coordinates through accurate discrimination. CONSTITUTION:The coordinate point trains forming strokes are stored to a stroke information storage circuit 1.

A flexion point extracting circuit 4 defines the start and end points P1 and Pn in the stroke at both ends and decides a point Pi where the distance of a straight line is maximum between points in the stroke. Then the value (i) is set to a register 5. Thus an arithmetic circuit 6 is started and the value m=(i+1)/2 is stored to a register 7. While the contents (n) of the register 3 are set as they are to a register 8, and an extraction circuit 9 is started with points Pm and Pn defined as the start and end points respectively. The value (j) showing the position of an obtained flexion point Pj is stored to a register 10 and compared 11 with the contents of the register 5. Then the point Pi is decided as the 1st type flexion point when i=j is satisfied and as the 2nd type flexion point with inot equal to j respectively.

Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To unnecessitate the setting of a communication speed by a person and to efficiently transfer data by automatically deciding the optimum communication speed that is suitable for an input-output I/F cable length which connects inter-devices or inter-input-output devices of a communication controller. SOLUTION: When power is inputted to a communication controller 1, reference voltage is outputted from a reference voltage part 4 to a voltage detecting signal line 3, and voltage that moves around the line 3 one time brings about voltage drop due to direct current resistance. A voltage drop detecting part 5 compares the voltage that circulates the line 3 once with the reference voltage and calculates an input-output I/F cable length that connects the controller 1 and an input-output device 8 based on the value X which calculates a voltage drop amount of the line 3. A communication speed deciding part 6 instructs a clock generating part 7 to generate the clock of a communication speed that is decided based on the cable length. Thereby, the optimum communication speed is automatically decided in accordance with the cable length and data transfer is efficiently performed.

Filed: 1985-10-29
Abstract: PURPOSE:To reduce the possibility of line breakage at electrodes and enhance the yield of thermal head products, by connecting resistance heating elements to individual electrodes and to a common electrode on a partial glaze. CONSTITUTION:The connecting positions 8 of common electrode side electrodes 6 for supplying electric power to resistance heating elements 4 and a common electrode 7 are located on a partial glaze 2. Therefore, at the boundary part between an unglazed part on the common electrode 7 side and the glaze, only the common electrode is present and minute patterns are absent, so that troubles due to the breakage of electrode patterns do not occur at this part.
