Title: Driving circuit for thin film el display device
Inventor: SHOJI KAZUO
IPC: G09G3/30
Filed: 1987-12-28
Abstract: PURPOSE:To correct the luminance variation caused by the number of light emitting picture elements by adding a capacity means between the first common terminal to which the potential of the first level is applied, and the second common terminal to which the potential of the second level is applied. CONSTITUTION:In a second modulation voltage charge and write period in N driving, the potential of data side electrodes X(X1-X2) containing a light emitting picture element tends to further rise. However, since a current flows to a capacity means 15 through a one-way conducting element from a data side electrode X, the capacity means 15 is charged. Accordingly, when there are many light emitting picture elements, the potential of the capacity means 15 further rises, and the potential of the data side electrode X containing the light emitting picture element also becomes high. On the contrary, when the number of light emitting picture elements is small, the potential of the capacity means 15 does not rise so high and the potential of the data side electrode X does not become so high either. In such a way, a phenomenon by which the luminance becomes higher when the number of light emitting picture elements is small, than when there are many light emitting picture elements is corrected.

Abstract: PROBLEM TO BE SOLVED: To reduce electromagnetic radiation noise by changing a switched output voltage, the max. value of a current waveform, a present state value or a min. value, etc., in several stages and selecting a circuit parameter to permit an S/N ratio expressing the dispersion of output signals, based on an input signal and a sensitivity expressing the inclination of an input and an output to be optimum. SOLUTION: An input signal processing circuit generates the input of a switching circuit, which is given to a gate circuit, observes an output detecting circuit by a waveform observing equipment and a switching waveform is obtained. A test circuit observes the switching output waveform by excluding a feedback circuit, in order to observe only a switching function and observes a linearity in the input/output. The S/N ratio and the sensitivity are introduced as a measure for evaluating the linearity. The S/N ratio expresses the dispersion of an input/output characteristic and the sensitivity expresses the inclination of the input/output. A parameter value is allotted, based on an orthogonal condition so as to obtain the input/output characteristics. A test for optimizing and recognizing a parameter is executed, as necessary.

Filed: 1995-12-03
Abstract: PROBLEM TO BE SOLVED: To self-travel on a superhighway by forming a stopper part rising from a bottom surface part in a hollow part, and forming a hollow part inside surface and a stopper as a noncontact structure under a static load of a machine body. SOLUTION: It is desirable that a stopper 7, side surface parts 3 and 4 to constitute a hollow part 6 and an inside surface of an outside surface part 5 do not contact with each other under a static load. On the other hand, when a load not less than that is applied, since these inside surface and stopper 7 contact with each other, a spring constant is suddenly increased. Therefore, at load time, the stopper 7 and an inside surface of the hollow part 6 collide with each other, and an effect of checking abnormal displacement of a segment (s) is exhibited. Therefore, it is necessary to sufficiently keep strength of the stopper 7 contacting with the inside surface of the hollow part 6. Therefore, it is desirable that a supporter 10 be embedded in the stopper 7. That is, the supporter 10 is welded to a plate 8, and strength of the stopper 7 is secured by this supporter 10.

At that time, arc current flows to an electrode 13 through the coil 18 and the resultant magnetic fluxes of the generated magnetic field and the magnetic field attributed to secondary current become proper. As a result, it becomes easys to connect the coil 18 and arc can be extinguished at current zero point while being rotated.

IPC: H01L29/78
Filed: 1989-12-28
Abstract: PURPOSE:To make possible an increase in the breakdown strengths of both P-channel and N-channel transistors in a C-MOS constitution by a method wherein a low-concentration drain layer, which has an interval between the low-concentration drain layer and an Si3N4 film pattern at the ends of the channels of the transistors and includes a high concentration drain layer, is formed. CONSTITUTION:A first low-concentration drain layer 5 is formed by a self- alignment ion-implantation of boron using an Si3H4 film as a mask. Subsequently, a second low-concentration drain layer 7, which has an interval of 0.5 to 2.0mum between the layer 7 and the Si3N4 film pattern 3 at the ends of channels and includes a high-concentration drain layer, is formed by an ion-implantation using a resist pattern 6 as a mask. As the layer 7 includes completely the highconcentration drain layer, an increase in a breakdown strength of 60V or higher becomes possible and as the resistance of the layer 7 can be made small, a gm can be increased. Moreover, in the case of a C-MOS constitution, an increase in the breakdown strengths of both P-channel and N-channel MOS transistors can be realized.
