Title: Single wafer processing gas-phase growth device
Inventor: TANAKA KAZUHIRO
IPC: H01L21/22
Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To significantly reduce sticking of reaction by-products to the side surface of a reaction vessel. SOLUTION: Auxiliary gas B comprising hydrogen gas or inactive gas flows out from an inclined through tube 17 to the inside of a reaction vessel 1 and then flows downward along the side surface of the reaction vessel 1. A wafer 7 is rotated rapidly by a wafer mount part 8. A reaction gas A, flowing out of the outside periphery pat of the wafer 7 in fast rotation, advances to the side surface of the reaction vessel 1. However, the reaction gas A, heading for the side surface of the reaction vessel 1, is blocked by the auxiliary gas B flowing its side surface, resulting in almost no contact to the side surface of the reaction vessel 1. Thus, the amount of reaction bi-products sticking to the side surface of the reaction vessel 1 is significantly reduced.

IPC: E05B77/38
Filed: 1990-07-25
Abstract: PURPOSE:To improve durability by forming an energy accumulation device out of a soft elastic member and a relatively hard elastic member, and by first deflecting the soft elastic member and then the hard elastic member at the time of energy accumulation. CONSTITUTION:An energy accumulation device is placed on a rotation transmitting route between a reducing gear 15 for transmitting the rotation of a motor 13 to an input gear 21, and a pinion gear 17, and is formed also out of a spring 16 and a rubber 30. At the initial stage of accumulational operation, the spring 16 is deflected by a gap 15g by the rotational power transmitted from the side end of a protruded part 15c of the gear 15 to a load receiving part 16a of the spring 16. The spring is then compressed along a rubber 30 of a soft elastic member, and while the amount of deflection of the spring 16 is regulated in a certain range, the transmission of the impact force is prevented by the deflection power of the rubber 30. Durability can thus be improved, and breaking of the gear can be prevented.

Filed: 1987-08-13
Abstract: PURPOSE:To simultaneously compare a plurality of sequences within a short calculation time, by repeating parallel arrangement at every two sequences and the correction of already parallelly arranged sequences in DNA sequence. CONSTITUTION:One of many sequence data X1, X2,..., XN-1, Xref is set to reference sequence data Xref. In a sequence data parallel arrangement processing part 5, sequence elements are allowed to correspond between Xref and arbitrary objective sequence data Xn to perform parallel arrangement processing.

IPC: G01S17/10
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To correctly detect the original distance to an object by removing distance data under previously set distance data by a removing means. SOLUTION: A ranging part 104 measures a time between the laser shooting pulse of a light transmitting part 101 and the laser receiving pulse of a light receiving part 103, and a distance up to an obstacle 102 is computed. A data memory part 105 stores distance data in 1 scan computed by the ranging part 104. A clustering part 106 obtains data at every reflecting object (for example a reflector or the like) based on the computed distance of one frame portion (one time of scanning), and obtains the center of gravity. When the minimum value in data at every clustered reflecting object, or a data under a previously set threshold value is continuously generated on a fixed level frame, a wiper detecting part 107 judges it to be dirt on a front glass 4, and when the level frame is not continued, it judges to be a wiper 5, and both distance data are eliminated and removed. A vehicle recognizing part 108 recognizes a reflecting object except the removed reflecting objects as an obstacle such as a vehicle or the like.
