Title: Fabrication of layer-built solar cell
Inventor: SHIMAZU SHOGO
IPC: H01L51/30
Filed: 1985-04-27
Abstract: PURPOSE:To enable the employment of an organic substance or the like which is difficult to be used conventionally by forming a semiconductor film by use of Langmuir-Blodgett's technique. CONSTITUTION:P-type semiconductor substance 2 is solved in a solvent of high evaporative property such as chloroform and the drops of its are dropped on the surface of water one by one. The solvent evaporates soon and a single molecule film of the P-type semiconductor substance 2 is formed on the water surface. This single molecular film is formed on a surface of a metallic substrate 1. After similar process, an N-type semiconductor layer 3 is formed on the P-type semiconductor layer 2. These processes are repeated in order to accumulate the desired number of PIN layers. On the last N-type semiconductor film, a transparent conductive film 4 such as of ITO (InSn Oxide) or NESA glass is evaporated to compose an electrode, and a layer-built solar cell is fabricated. The reason why an I-layer 5 is formed is that a length of an aliphatic compound is longer than that of a coloring matter and the layer of only the aliphatic compound is formed between a P-type coloring matter and an N-type coloring matter to become an insulating layer.

Title: Liquid crystal display device
Inventor: TAKAHATA MASARU
IPC: G09G3/36
Filed: 1991-04-23
Abstract: PURPOSE:To obtain superior display quality even if field-effect mobility decreases owing to variance among processes by making the width of a gate pulse when a plus drain signal is applied longer than the width of the gate pulse when a minus drain signal is applied. CONSTITUTION:The timing of gate signal groups VG1-VG480 in the row-by-row inverted driving of a-Si TFTs is as shown in figure. In the figure, VDK is an optional drain signal, t2 the gate pulse width when the drain signal is plus, t3 the gate pulse width when the drain signal is minus, VC the center potential of the amplitude of the drain signal. Namely, the gate pulse width t2 when the drain signal is plus is longer than the gate pulse width t3 when minus. Therefore, when the drain signal is plus, the driving ability of the a-Si TFTs is low, but the gate pulse width t2 is long, so the drain signal is applied sufficiently to a liquid crystal terminal part.

Filed: 1983-05-24
Abstract: PURPOSE:To prevent creation of noise through control of vibration of a rack guide produced due to a clearance between the rack guide and a guide hole, by a method wherein a rack bar is formed in an oval. CONSTITUTION:In a rack guide 20, an outer diameter DL in relation to a direction extending orthogonal to the direction of reciprocating motion of a rack bar 4 is set to a wider size than that of the inner diameter of a guide hole 10, and an outer diameter DS in relation to the same direction as that of the reciprocating motion of the rack bar 4 is set to a narrower size than the inner diameter of the guide hole 10 to form the rack guide into an oval shape having a longer size which forms the outer diameter DL. Rotation of a pinion 2 in linkage with steering control causes the rack bar to be reciprocated in linkage therewith as the rack bar 4 is guided by a rack guide 20. The rack guide 20 mates inwardly of the guide hole 10 in a manner to be elastically reduced in the size of a long size part A, and a clearance between the outer periphery of the rack guide 20 and the inner periphery of the guide hole 10 is kept in a zero condition to inhibit a device against vibration at the interior of the guide hole 10.

Filed: 1989-04-12
Abstract: PURPOSE:To prevent the beat sound generation by collision between a piston and a housing by forming an oil passage, which communicates a hydraulic chamber with an oil chamber partitioned off on the rear side of a piston when the piston has lowered to the vicinity of the lower end position. CONSTITUTION:A hydraulic chamber 24 is partitioned off between a piston 22 and a cylinder 21. By introducing hydraulic pressure to a hydraulic chamber 24, a plunger 23, which operates in a body with the piston 22, presses down a valve 21 resisting a valve spring 2. Hereupon, an oil passage 31 of small diameter, which communicates the hydraulic chamber 24 with an oil chamber 27 partitioned off on the rear 22B side of the piston, is formed in a housing 26. Furthermore, a check valve 32, which checks the reverse flow from the oil chamber 27 to the hydraulic chamber 24, is interposed in the oil passage 31. By shock absorbing mechanism consisting of such oil passage 31 and check valve 32, the shock at the time when the piston 22 collides against the housing 26 is softened. The shock absorbing mechanism in this case is constituted in the housing 26, so the necessity of providing it additionally on the outside disappears.
