Title: Powder strewn sheet for firing ceramic
Inventor: TOMINAGA TAKASHI
IPC: F27D3/12
Filed: 1988-04-05
Abstract: PURPOSE:To achieve secure adhesion between compressed powder base plates stacked and prevent the reactive adhesion between the compressed powder base plates at the time of firing by forming a strewn layer of inorganic powder on a combustible sheet with an adhesive layer inbetween and placing it between the compressed ceramic powder base plates. CONSTITUTION:Adhesive is applied to one or both sides of a combustible sheet, and inorganic powder such as ceramic powder is strewn to this surface, which is used as a powder strewn sheet for firing ceramics. A uniform powder layer can be formed regardless of the size of the powder, and its manufacture is also much simplified. When a compressed ceramic powder base plate is fired by using this powder strewn sheet for firing ceramics, the resultant compressed powder base plate yields less nicks because of the uniform powder layer on the sheet, and the amount of powder required can be reduced. For the sheet material, one which is dissolved or burnt to become gasified or carbonized at the time of firing the ceramics is popularly used, a typical example of which is a polymer film material.

Title: Infrared distance measuring instrument
Inventor: IWASAKI TOSHIO
IPC: G01C3/06
Filed: 1987-04-06
Abstract: PURPOSE:To obtain a small-sized infrared distance measuring instrument capable of measuring the distance to a target body by one infrared camera by constituting an optical path for picking up projection light from the target body by the infrared camera through 1st and 2nd reflecting mirrors. CONSTITUTION:The reflecting mirrors 6 and 7 slant at 45 deg. to the optical path 4 which connects the target body and infrared camera 2 for picking up its image, so optical paths 4 and 5 become parallel to each other and their distance is set to l. One end of the reflecting mirror 7 is rotated on the optical path 4 around the other end P to a position R to evade disturbance to the visual field of the camera 2 and when the image of the target body is picked up through the optical path 5, one end of the reflecting mirror 7 is rotated around the other end P to a position Q to secure the 45 deg. angle of a reflection point (d) to the optical path 4. Consequently, images of the optical paths 4 and 5 are picked up on the image pickup plane of the camera 2 at the same time and the angle of incidence is measured in real time. A measurement of distance is therefore taken by one infrared camera.

Title: Preventive method for crystal defect of semiconductor substrate
Inventor: IKEDA YUUSHIROU
IPC: H01L21/02
Filed: 1990-03-30
Abstract: PURPOSE:To prevent a crystal defect from generating in the surface of a semiconductor substrate by depositing an SiN film onto the rear of a semiconductor substrate and previously leaving the SiN film at all times even at the time of the manufacturing process of a semiconductor device. CONSTITUTION:An SiO2 film 2 is deposited only onto one surface 1a of a semiconductor substrate 1, one surface of which is specular-finished, through a decompression CVD method, and an SiN film 3 is deposited onto the other surface of the semiconductor substrate 1 through the decompression CVD method. Only the SiO2 film is removed selectively through wet etching. Consequently, the SiN film 3 remains on the other surface not specular-finished, the rear 1b, of the semiconductor substrate 1. The SiN film 3 generates tensile stress toward the peripheral section of the semiconductor substrate to the rear of the semiconductor substrate. Accordingly, crystal defects are concentrated to the rear 1b of the semiconductor substrate 1, thus preventing the generation of the crystal defects in one surface 1a, which is specular-finished.

Abstract: PURPOSE:To decompose and annihilate a thermal donor in a semiconductor thin-film, to form a thin-film transistor having the fast speed of response and to use a substrate having the comparatively low melting point by crystallizing the semiconductor thin-film and heating the semiconductor thin film by applying laser beams. CONSTITUTION:A first semiconductor thin-film 3 formed onto an insulating film 2 is irradiated with laser beams from the substrate 1 side or the semiconductor thin-film 3 side and crystallized. An argon laser, etc., are used preferably as laser beams. Second semiconductor thin-films 4a, 4b as a reverse conductivity type are formed onto the thin-film 3. Laser beams are applied from the substrate 1 side, and the first semiconductor thin-film 3 is heated. An excimer laser is employed preferably as the laser beams. Since the excimer laser is composed of short-wave length beams, the excimer laser is used in an extent that it is absorbed only by the extreme surface layer of the semiconductor thin-film 3, but a thermal donor is decomposed, and the mobility of electrons and holes is improved. Sections near joining sections with the layer 3 of the layers 4a, 4b are thermally annealed, thus improving joining characteristics while also lowering the interface level of a gate insulating film 5 and the layer 3.
