Title: Organo metallic vapor phase epitaxy equipment
Inventor: KASAI KAZUMI
IPC: H01L21/205
Filed: 1986-03-14
Abstract: PURPOSE:To simplify the structure of the title equipment as well as to facilitate the control of a crystal growing layer by a method wherein a gas circulating hole is provided at the required position on the partition wall with which a reaction tube is divided into two parts, and the feeding of raw gas to the substrate to be grown and the stoppage of raw gas are performed by opening or closing the gas circulation hole. CONSTITUTION:Carrier gas is made to flow in from a flow-in hole 26, raw gas is made to flow in from a flow-in hole 27, and a gas circulation hole 31H is closed by a shielding plate 32. Then, a substrate (wafer) placed on a susceptor is heated up, and when it reaches the required temperature, the gas circulation hole 31H is opened by moving the shielding plate 32, and raw gas is made to flow to the surface of the wafer. After a prescribed crystal growing layer has been formed, the gas circulation hole 31H is closed by moving the shielding plate 32. As a result, the raw gas is shut off completely. If other crystal growing layer is formed thereon, a steep gradient junction can be obtained. Consequently, the controllability of the crystal growing layer can be improved by means of a simple structure.

Title: Method for sticking polarizing plate
Inventor: SERA TSUKASA
IPC: G02B5/30
Filed: 1987-03-12
Abstract: PURPOSE:To improve the sureness of sticking and selectivity of polarizing plates by using a supporting device provided with a self-adhesive tape, roller and weight, rolling a base plate and sticking the polarizing plate to the outside surface of a substrate. CONSTITUTION:The substrate 8 for a liquid crystal display element is placed on the base plate and after the polarizing plate 7 and the substrate 8 are so adjusted as to be integrated while the separator 16 of the polarizing plate 7'' is not stripped, the separator 16 is tripped and the polarizing plate is inclined in such a manner that the self-adhesive layer 15 faces downward. The self-adhesive tape 5 is then adhered onto a surface protective film 9 on the side opposite from the starting part for sticking. The self-adhesive part of the self-adhesive tape is required only where the tape contacts the polarizing plate 7. The tape 5 is then wound on the roller 4 and the weight 6 is lowered. The roller 1 for sticking the polarizing plate is rotated in the direction of an arrow at this time and the base plate is simultaneously rolled by the roller for rolling 2 to stick the polarizing plate 7 to the substrate 8; thereafter, the surface protective film 9 is stripped. The sticking of the polarizing plate and the substrate is thereby permitted without allowing air bubbles to enter the same and the flawing of the surface of the polarizing plate during the sticking is obviated.

IPC: F01N3/28
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To enhance the durability of a heating surface by protecting it from thermal shock in a reducing agent vaporizing device by which after having been heated and vaporized, the reducing agent is supplied to a NOx catalist. SOLUTION: In a reducing agent vaporizing device by which after having been heated and vaporized, the reducing agent such as a liquid fuel is passed in the direction of the arrow F into the inside for supplying it to a NOx catalist, for instance, for an exhaust emission control device of an internal combustion engine; a heating wire 12 is rarely and then densely arranged on a cylindrical body 14, so that a temperature gradient that the temperature on the upsteam side is low and that on the downstream side is high is formed. Thus, the temperature difference between the reducing agent and the inside surface being the heating surface can be set to be less than a critical temperature difference (known by experiments) that breaks the heating surface by the thermal shock at any position, and also it can be set to that the reducing agent can be sufficiently heated. The temperature gradient can be realized even by changing the thickness of the heating surface.

Filed: 1989-03-13
Abstract: PURPOSE:To measure the volume of loaded matter without being almost affected by a change of the weather conditions of the circumference with high accuracy by measuring the distance up to the loaded matter on a transport ship by an optical distance meter. CONSTITUTION:Optical distance meters L1, L2 are shaken in directions approaching each other to measure the distances up to loaded matter 14 and the angles corresponding to the measured values are stored. Next, the distance meters L1, L2 are shaken in directions space part from each other and the distances up to the loaded matter 14 are measured in the same way to be stored along with the shaking angles of the distance meters measured by an angle sensor. When the difference between the average values of those measured values is larger than a predetermined value, since a transport ship is inclined, the respective measured values are corrected. When the transport ship is judged to be not inclined at a predetermined angle or more, the height of the pile of the loaded matter 14 is operated and the cross-sectional area thereof is calculated on the basis of said height. Therefore, the volume of the loaded matter 14 is calculated.

Abstract: PURPOSE:To reduce the influence of disturbing noises at the time of sequential control over the weight coefficient of a weight circuit, by controlling the weight coefficient in the same direction as a signal transmission direction and in a time nearly equal to the unit delay time of a delay element. CONSTITUTION:Delay element 11 has taps (t1) to (tn), each of which is applied with input signal Vin and a delay signal added together by weight circuit 12. Weight circuit 12 multiplies input signal Vin by a random weight coefficient and extracts the product, and the weight coefficient is controlled sequentially by control circuit 13 consisting of shift register 14, gate circuit 15 and analog memory 16.

Abstract: PURPOSE:To enable obtaining a low threshold even in an InP laser by burying and growing an n-type layer on one side of a mesa of double-heterostructure having an active layer sandwiched between p- or n-type clad layers, and a p-type layer on the other side thereof, and forming electrodes on the buried layers. CONSTITUTION:A mesa stripe of three-layer structure having an active layer 3 sandwiched between a first conductivity type clad layer 2 and a first or second conductivity type clad layer 4 is formed on a semi-insulating substrate 1, first conductivity type buried layers 5 and 6 are selectively buried and grown on one side of the mesa stripe and second conductivity type buried layers 7 and 8 on the other side, and electrodes 9 and 10 are installed on the buried layers. Therefore, carriers are implanted uniformly and efficiently without distribution because they are implanted through the clad layers 2 and 4 along the width of the active layer 3. A quantum well does not deform, the substrate does not thermally metamorphose, and light absorption does not increase because the carriers are implanted not by diffusion. Thereby a low threshold is obtained even if used in an InP laser.

Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To obtain excellent display uniformity against in homogeneous heating as an external factor by specifying the relation between the gap thickness near peripheral seal and the gap thickness in the center of the panel. SOLUTION: The gap thickness d1 near the peripheral seal and the gap thickness d2 in the center of the panel satisfy the relation of d1>d2+(average film thickness of the color filter and the black matrix in the display pixel region-film thickness of the black matrix out of the display pixel region). A spacer is dispersed in the pixel region to maintain the gap thickness. In the peripheral part, a sealing resin in which a glass fiber or glass beads are dispersed and mixed is applied outside of the pixels, namely, in the frame region to seal the liquid crystal. Thus, the gap thickness near the peripheral seal is specified to be larger than the gap thickness in the center plus the difference between the sum of average film thickness of the color filter and the black matrix in the display pixel region and the film thickness of the black matrix outside the display pixel region.
