IPC: C04B35/81
Filed: 1999-10-22
Abstract: PROBLEM TO BE SOLVED: To eliminate such a problem of the conventional AlN sintered compact that the characteristics enhancing effect by coarse particles can not be obtained because of the adhesion lack between the AlN matrix and the coarse particles used for enhancing the strength and toughness. SOLUTION: This AlN sintered compact 5 comprises the sintered compact matrixes 1 constituted mainly of AlN particles 2 having 3 μm or smaller average particle diameter and the coarse particles 4 which are dispersed among the matrixes 1, are constituted mainly of aluminum nitride and aluminate and have 4 μm or longer length of at least one side. The aluminate existing in the grain boundary phase 3 or the like is made to exist on the surface of the particle 4 so that the existing aluminate amount satisfies the inequality: W1>W2 (wherein W1 is the aluminate amount per unit area of the coarse particle; W2 is the aluminate amount per unit area of the matrix 1 in the optional cross section).

Title: Manufacture of semiconductor element
Inventor: TAMAKI SADAJI
IPC: H01L29/73
Filed: 1993-12-01
Abstract: PURPOSE:To stabilize emitter-base bonding pressure resistance of a semiconductor element by forming a sidewall at a layer-built part of a nitride film and an oxide film on an intrinsic base prior to ion implantation to form an external base region and using it as a mask for ion implantation. CONSTITUTION:A nitride film 101 and on top of that an oxide film 102 are formed over an intrinsic base forming region. Here, when the oxide film 102 is used as a mask for etching the nitride film 101, the nitride film 101 is not undercut. Next, a nitride film 103 is formed over the entire surface and an oxide film 104 is formed thereon. Then, the oxide film is treated with anisotropic etching, and on a side wall of the nitride film 101 and the oxide film 102 part (including the nitride film 103) a sidewall 105 is formed. The nitride film 101 and the oxide film 102 part on which the sidewall 105 is formed is used as a mask, and a p<+> type region or an external base region 106 is formed by ion implantation. As a result, no contact between an emitter and the external base occurs.

IPC: G01S13/74
Filed: 1992-11-12
Abstract: PURPOSE:To reduce the communication traffic volume of a host computer by sending information, which is read by a sensor when a visitor moves, to the host computer. CONSTITUTION:When the visitor carrying an ID transmission card 11 moves into the detection area of a sensor 21, the sensor 21 detects the ID code of the ID transmission card 11 and sends it to a controller 5 together with the identification number of the sensor as sensor information D21. A retrieval part 54 of the controller 5 retrieves the sensor information of the sensor 21 stored in a storage part 53 several seconds before and detects the change of the sensor information by comparing the retrieved sensor information with the received sensor information D21. When no change is generated, transmission is stopped or when any change is generated, a control signal C1 is sent so as to perform transmission. A transmission control part 55 generates card information (such as the ID code, sensor ID number and detection date and time) D5 and transmits it to a host computer 4 corresponding to the control signal C1.

Abstract: PURPOSE:To improve the disposal aptitude and the light shielding property of a film pack. CONSTITUTION:Pressure openings 20 are formed on the base plate 11b of a case 11. A light shielding sheet 30 is arranged between a film unit 12 and the base plate 11b. The light shielding sheet 30 is constituted of an elastic member. Unit supporting projections 22 are formed on the base plate 11b along both edge parts of the light shielding sheet 30 so that the projections may project in a circular-arc shape. Both edge parts of the film unit 12 are supported by the unit supporting projections 22. The unit supporting projections 22 are formed so that they may curve in accordance with the curvature of the lowermost part of the film unit 12 which is generated from a thickness difference between both end parts provided with a developer pod 12b and a trap part 12c and the central exposure part 12a when the film unit 12 having the prescribed number of film sheets is stored in the case 11. Thus, even in the case of eliminating a metallic pressure plate, the film unit 12 can be pushed up to an exposure aperture 13 by the unit supporting projections 22 and held in the case 11, so that the light shielding performance is improved.
