    • PURPOSE:To prevent the short circuit between a gate and cathode when an intermediate buffer plate is compressed to a pellet, by providing a recess at a part facing an auxiliary thyristor part of the intermediate buffer plate. CONSTITUTION:A direct light igniting type auxiliary thyristor is formed at a central part, and an auxiliary or main thyristor is formed around said auxiliary thyristor. Thus a semiconductor pellet 20 is constituted. An anode side external electrode 35 is connected to an anode electrode 40 of the pellet 20, and a cathode side external electrode 30 is provided at a pellet cathode electrode through an intermediate buffer plate 1. At the center of the intermediate buffer plate 1, an opening for passing an optical fiber 17, which introduces igniting light, is provided. In a direct light igniting type semiconductor controlled rectifying device constituted in this way, a recess is formed at a specified position of the intermediate buffer plate 1, i.e., a part facing the auxiliary thyristor part. In this constitution, the buffer plate 1 and the auxiliary thyristor part are not contacted even though the buffer plate 1 is compressed to the pellet 20 by the external cathode electrode 30. Therefore, the short circuit between the gate and the cathode of the auxiliary thyristor part can be prevented.

    • PURPOSE:To prevent a discharge phenomenon, by conductively connecting a metal connector, which is provided at the intermediate part of an insulating seal, to an anode electrode, or a cathode electrode, or a part having the same potential as that of the electrode. CONSTITUTION:In a light igniting type thyristor, metal lead wires 13A and 13B are connected to a connector 9, which is provided at the end part of an optical fiber 10. The lead wire 13A is connected to an external cathode electrode 6 through a metal flange 7K. The lead wire 13B is connected to a cathode electrode 4. In this constitution, the metal connector 9 is always kept at the same potential as that of the cathode electrode 4 when the thyristor is operated. Therefore, a discharge phenomenon between the connector 9 and the external cathode electrode 6, the flange 7K, and the like can be prevented. When the connector 9 is provided in the vicinity of an anode electrode 3, the anode side of said leads 13A and 13B are connected to the metal flange and the anode electrode.
    • 目的:为了防止放电现象,通过将设置在绝缘密封件的中间部分的金属连接器导电连接到阳极电极或阴极或具有与电极相同电位的部分。 构成:在轻型晶闸管中,金属引线13A和13B连接到设置在光纤10的端部的连接器9.引线13A通过金属连接到外部阴极电极6 法兰7K。 引线13B连接到阴极电极4.在这种结构中,当晶闸管工作时,金属连接器9总是保持与阴极电极4相同的电位。 因此,可以防止连接器9和外部阴极电极6,凸缘7K之间的放电现象。 当连接器9设置在阳极电极3附近时,所述导线13A和13B的阳极侧连接到金属凸缘和阳极电极。

    • PURPOSE:To permit a high-impurity density n type conductive layer and a low- impurity density n type conductive layer to be simultaneously formed in one diffusion heat treatment without any restriction on the pattern size and density. CONSTITUTION:No oxide film is formed in a high-impurity density region A of a silicon substrate 1. On the other hand, in a low-impurity density region B, an oxide film 2b of thickness T1, as a mask, is formed on the surface of the silicon substrate 1, and in a region C where no n type impurities are diffused, an oxide film 2c of thickness T2 (larger than T1), as a mask, is formed on the surface of the silicon substrate 1. Under this state, P and As are implanted. As a result, P is implanted into both the regions A and B, while As is implanted into only the region A. After the implantation of P and As, the oxide films 2b and 2c are removed by etching, and a heat treatment is applied to form a P-diffused layer 5 and an As-diffused layer 6. In this case, the allowable range of the thickness T1 of the ion transmission control film 2b provided on the low-density region B is considerably wide.

    • PROBLEM TO BE SOLVED: To suppress the lowering of brightness and contrast by preventing the lowering of brightness due to contamination of liquid crystal caused by columnar spacers and the generation of an electric short-circuit between substrates. SOLUTION: This device is equipped with polarizing plates POL1, POL2 and a driving means for applying a driving voltage to a group of electrodes. The device is provided with the arrayed structure of the electrodes arranged as the group of electrodes applies a primarily parallel voltage to boundaries between orientation controlling layers ORI1, ORI2 and a liquid crystal layer LC and columnar spacers SP formed by patterning of an overcoat layer OC film-formed on the upper layer of black matrices BM an color filters FIL and under the lower layer of the orientation controlling layer ORI2. In this case, the base part and the top part of the columnar spacer SP have about the same area, its cross-section in the direction in parallel to the plane of substrates has an acute angle shape to the direction of rubbing and the top part of the orientation controlling layer ORI2 film-formed on the upper layer of the columnar spacer SP is brought in contact with the orientation controlling layer ORI1 of the other substrate SUB1.

    • PROBLEM TO BE SOLVED: To improve the picture quality of a liquid crystal display device by forming a polycrystalline silicon film oriented in a specific direction on a glass substrate as the active layer of a thin film semiconductor device. SOLUTION: When a peripheral driving circuit is formed in a liquid crystal display device LCD by using a polycrystalline silicon thin film transistor(TFT) which is mainly aligned in 111}, in which carriers can move with high mobility, the number of the picture elements of the displaying section 5 of the display device LCD can be increased. The driving circuit of the display device LCD is generally divided into a scanning circuit 8 and a signal circuit, and the signal circuit is composed of a multiplexer 9, a divided matrix switch 10, and a high- speed shift register 11 externally attached to a substrate 4. The pixels of the displaying section 5 are composed of TFTs 20 which are active elements and capacitors 19 consisting of liquid crystals which are displaying media and picture electrodes and arranged in a matrix-like state. The number of the pixels of the displaying section 5 varies principally depending upon the characteristics of the multiplexer 9 and partitioned matrix switch 10 of the signal circuit.

    • PROBLEM TO BE SOLVED: To prevent the malfunction of a display from occurring even when a high potential such as static electricity, etc., is impressed thereon from outside a liquid crystal panel surface. SOLUTION: A liquid crystal display device has such a configuration as it comprises a liquid crystal panel and a backlight unit for making the light transmit a screen of this liquid crystal display panel; the liquid crystal panel comprises display electrodes in each picture element area on the liquid crystal surface side of one of the transparent substrates placed opposite to each other via a liquid crystal layer and a reference electrode arranged apart from the display electrodes; and an electric field component parallel to the transparent substrate generated between the display electrode and the reference electrode is made to control the light transmittance of the liquid crystal layer. In this case, at least in a picture element area on a surface opposite to the liquid crystal layer LC of the transparent substrate 1A on a side farther to the backlight unit, a transparent conductive film is formed in the same direction as the electric field component parallel to the transparent substrate, and also the transparent substrate with this conductive film formed thereon is two figures and more as thick as the length between the display electrode and the reference electrode, and secures an electric field component parallel to the transparent substrate generated between the display electrode and the reference electrode.
