Inventor: KAMATA MASATOMO
IPC: C22C33/02
Filed: 1993-12-21
Abstract: PURPOSE:To densify the 12%-Cr ferritic steel green compact by alternately repeating vacuum sintering and nitrogen-atmosphere sintering. CONSTITUTION:Twelve %-Cr ferritic steel powder is compacted and vacuum- sintered. In this case, the vacuum is controlled to 10<-1>-10<-6>Torr, vacuum sintering is conducted as before immediately before the densification is retarded after the start of sintering, the atmosphere is replaced by a nitrogen atmosphere, the compact is heated for a specified time and sintered, then the atmosphere is returned to the vacuum atmosphere, and the compact is sintered. The replacement is repeated optional times or the heating time is changed to control the extent of densification or to selectively remove the pores close to the surface. Since nitrogen is a powerful austenite forming element, the compact absorbs nitrogen by the sintering in the nitrogen atmosphere, and the crystal grain is refined and densified while the austenitic phase is deposited from the ferritic phase.

Filed: 1992-11-06
Abstract: PURPOSE:To detect a plurality of types of gases with a single sensor by adding a plurality of metallic oxides to a main constituent SnO2 with a specific composition ratio for constituting a gas receptive part and by changing the retention temperature. CONSTITUTION:When, for example, 1-10mol.% TiO2 which is tetravalent metallic oxide and 0.02-10 mol.% Nb2O5 which is pentavalent metallic compound are added to a main constituent SnO2 to constitute the gas receptive part of a gas sensor, the gas receptive part which has improved selectivity for gas to be detected when retention temperature is changed, is less influenced by external noise, and has a stable detection resistance can be obtained. According to this configuration, for example, the peak of sensitivity for 3000ppm H2 gas is within 550 + or - 50 deg. (range and that for 4ppm NOx exists at 200 deg.C. Also, the other gas cannot be detected at all at the retention gas where one gas is detected. Thus, when the retention temperature is changed between 100 to 700 deg.C a plurality of kinds of gases can be detected using a single sensor.

Title: Device for truing up side edge of sheet
Inventor: OBARA KAZUTOSHI
IPC: G03G15/00
Filed: 1994-12-26
Abstract: PURPOSE: To quickly and stably align the sheets differed from each other in ream weight and true up the side edge of sheets without interfering with the conveying speed by switching the sheet coveying speed of a skew conveying path when a sheet strikes a guide. CONSTITUTION: A sheet 50 strikes a guide 49 at 15IPS or at a half of the normal conveying speed 30IPS, and is conveyed to a conveying roller 46 with the side edge along the guide 49. When the sheet 50 is picked up by the conveying roller 46, a control circuit 52 increses the peripheral speed up to 30IPS based on the conveying speed of a motor 51 in preparation for the following sheet. However, when the speed at which the sheet 50 strikes the guide 49, is too low, the sheet collides with the following sheet, and thereby the speed must be reasonable in consideration of the sheet feeding interval. Thus, since the sheet 50 strikes the guide 49 at a lower speed than the normal sheet conveying speed, even a thin paper sheet, the ream weight of which is small, can be stably aligned and trued up with side edge of the sheet.

Title: Observing method of semiconductor surface
Inventor: OTAKE SHIGEYUKI
IPC: H01L21/66
Filed: 1993-11-29
Abstract: PURPOSE:To selectively observe the change of refractive index of semiconductor surface, by casting a P-polarized light of a wavelength which is not absorbed by surface structure, at a Brewster angle or an inclination angle approximate to it, and observing the reflected light from the surface of a thin film. CONSTITUTION:The light from a light source 1 is made to pass a polarizer 2, and a P-polarized light is obtained. It is casted on the substrate surface Sf, and the reflected light is observed. As the light source, a semiconductor laser whose wavelength is, e.g. 850nm wherein absorption is not caused by surface structure is used. The incidence angle theta is set as 7 deg. approximate to the Brewster angle, and a silicon photodetector 4 is used for measuring the reflected light. Thereby the change of a refractive index part and the change of an absorption part can be selectively detected, when the refractive index as well as absorption change at the same time or when only the refractive index changes. Hence the case that change is generated in the absorption part can be isolated from the case that change is generated in the refractive index part.
