Title: Color separation filter device
Inventor: MATSUMOTO MITSUHIRO
IPC: G02B5/20
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To accurately form an image of luminous flux on a line image sensor by sandwiching a color filter between two piezoelectric elements across filters at right angles to an optical axis without fail. SOLUTION: The color separation filter 8 is held between the two piezoelectric elements 7a and 8b and connected to the piezoelectric elements 7a and 7b by elastic buffer 11. Information when the piezoelectric elements 7a and 7b are displaced upward at a maximum is read by a line image sensor 6. In this case, the color separation filter 8 becomes perpendicular to the optical axis by the deformation of the elastic rubber 1 and deviation of an image formation plane due to the tilting of the color separating filter 8 is caused. Therefore, a general fluorescent lamp is usable as a light source and only one line image sensor 6 and one read circuit are needed to form the device to small size; and the optical axis never shifts whichever color filter makes a read and the luminous flux can accurately be formed on the line image sensor 6.

Filed: 1989-05-18
Abstract: PURPOSE:To detect the improper movement of a vehicle itself to prevent the generation of an accident by utilizing white lines on the road to measure the movement of the automobile itself based on the white lines and forecasting the succeeding traveling position. CONSTITUTION:The two-dimensional distribution of white lines L on the road is recognized by stereo vision using two TV cameras mounted on the vehicle V at real time, the succeeding traveling position of the vehicle V is forecasted from the positional relation of the measured vehicle V to the white lines L and the current speed and steering angle of the vehicle V and whether the forecasted result is on the proper position on the two-dimensional distribution of the white lines L or not is outputted as a signal.

Abstract: PURPOSE:To minimize noise-caused errors in the electrical angle of a motor so as to smoothly operate the motor by outputting a corrected electrical angle which is obtained by correcting an electrical angle based on a count value so that the electrical angle can fall within the electrical angle range of the motor when the electrical angle based on the count value does not fall within the range. CONSTITUTION:An electrical angle detecting section 16 detects the electrical angle phiE of a motor based on pulse signals S1 outputted from an encoder RE and the magnetic pole position detecting signals phiu, phiv, and phiw of a magnetic pole position detector 17. The section counts the pulse signals S1 and monitors the electrical angle based on the count value through the electrical angle range detected from the signals phiu, phiv, and phiw. In the case the electrical angle based on the count value does not fall within the detected electrical angle range, outputs a corrected electrical angle which is obtained by correcting the electrical angle based on the count value so that the electrical angle can fall within the range as the electrical, angle E.

Abstract: PURPOSE:To prevent the damage of gate insulating film as well as to manufacture TET arrays with an excellent yield rate by a method wherein the gate electrode of an insulating gate field-effect thin film transistor is composed of the first and second electrodes, a source electrode is composed of the third and fifth electrodes and a drain or a source electrode is composed of the fourth and fifth electrodes. CONSTITUTION:Electrodes 2, 3 and 4 are selectively formed using the Cr thin film which is vapor-deposited on a main surface of a glass substrate 1. A silicon oxide film as an insulating film 5 and an a-Si film as a semiconductor thin film 6 are deposited successively using a plasma CVD method. Subsequently, Al is vapor-deposited, and electrodes 7, 8, 9, 10 and 11, which will be turned to the source or the drain, are selectively formed. If protective transistors Tr2 and Tr3 are connected in three stages, a signal transistor Tr1 can be driven sufficiently to the level of a saturated current, and also the input impedance of the gate circuit above the gate voltage with which a saturated current will be given is reduced suddenly. Thus the number of connections of the protective transistors is increased or decreased as occasion demands.

IPC: H01L27/02
Filed: 1982-07-19
Abstract: PURPOSE:To realize the change of the device into one of low consumed power by enhancing current amplification factor (hFE) and reducing reactive current by a method wherein the impurity density of the semiconductor region in the periphery of the first region is reduced at the part opposed to the second region. CONSTITUTION:The device is formed in a structure wherein the density of the region 4b not opposed to the collector of a invertor transistor is enhanced more than that of the base region 4a at the part wherein the collector and emitter of the invertor transistor are opposed each other. In the presence of the N type high density region 4b, the emitter injection efficiency to the P-N junction region adjacent thereto decreases, and accordingly the most part of injector current is injected to the base region 4a opposed to the collector of the invertor transistor. Therefore, the current amplification factor (hFE) of the injector transistor is enhanced, thus the reactive current can be reduced, and then the change into a device of low consumed power can be contrived.
