Title: Manufacture of semiconductor substrate
Inventor: KIRITANI NORIHIKO
IPC: H01L21/762
Filed: 1989-03-27
Abstract: PURPOSE:To enlarge the domain of an element region and reduce cost by a method wherein, after a retaining part is arranged just under an element region forming part, the periphery is subjected to insulation oxidation, thereby constituting dielectric isolation. CONSTITUTION:By electrolytic etching, a cavity region 7 is selectively formed in a semiconductor substrate. Just under an Si epitaxial layer 4 to be subjected to dielectric isolation, a retaining part 3 composed of an N-type Si oxide film 6 is left, and a dielectric layer composed of an Si oxide film 5 is buried and formed in the retaining part 3 and the cavity region 7 by thermal oxidation. Thereby an element region 40 subjected to complete dielectric isolation can be simply formed in the inside of the semiconductor substrate, and a comparatively wide element region 40 can be completely isolated. Since, after that, the retaining part 3 and the cavity part 7 are subjected to insulation oxidation, a semiconductor substrate having an element region 40 of wide domain can be obtained at a low cost.

IPC: G11B7/09
Filed: 1981-05-20
Abstract: PURPOSE:To obtain a small-sized, lightweight and simplified structure and to improve efficiency by forming a magnetic gap between a fixed coil and a movable part which includes an annular magnet and an objective lens, and supporting the movable part by a coil spring. CONSTITUTION:For example, when a magnet 1 is magnetized to have an N pole at the upper part and an S pole at the lower part, a flow 1a of magnetic flux crosses a bobbin 6 and an electromagnetic coil 7 through the magnet 1 and a yoke 2, reaches a yoke 9, and then return to the S pole through an electromagnetic coil 8, the bobbin 6, and a yoke 3. When currents flow through the electromagnetic coils 7 and 8 wound in said magnetic circuit in such a way that the current flow in the opposite directions, those two coils generate equal forces in the axis direction 4a. Since the coils 7 and 8 are fixed, an objective lens 4 moves in the axial direction by reaction to perform stable driving by a coil spring 10, and the size and weight are reduced; and the efficiency is improved and the structure is simplified.

Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To notify a user of installation omission of a dedicated port monitor and to urge the user to install it by embedding message data notifying the absence of a standardized dedicated port monitor in job information. SOLUTION: A host device 2 is equipped with a dedicated port monitor 13, and the burden of a printer 3 is reduced. When the device 2 is connected to the printer 3, even though a printer driver 12 is installed on the device, there is danger of forgetting to install a dedicated port monitor 13. In such a case, even though output results outputted from the printer 3 consist of a print output part whose meaning is unclear obtained by printing and outputting a command constituting job information 23 and a print output 31 by print data 22, warning is included in its first page by additional data 24 and printed and outputted. Thus, they become decodable output results to a user, and it is possible to recognize installation omission of the port monitor.

Abstract: PURPOSE:To conduct purfication by simultaneous removal of CO2, H2S, NH3 and HCN from a gas contg. a hydrocarbon and CO2 without the necessity of receiving heat supply from outside, by treating the aforesaid gas with a fluidized bed for purification composed of particles of CaO as a main component. CONSTITUTION:A high-temp. raw gas contg. a hydrocarbon and CO2 is contacted with water in a recuperator 1, thereby generating steam. The gas mixture thus obtd. is introduced into a fluidized bed 3 for purification of a CO2 absorber 2 composed of particles of CaO as a main component, thereby causing the CO2 in the gas to be absorbed by CaO. By the heat energy generated at this time, the hydrocarbon is decomposed, and H2S, NH3, HCN, etc. are removed. The high-temp. gas thus prepd. is heat- exchanged with water in a heat exchanger 4, thereby generating steam. Thus, the heat energy is recovered. On the other hand, the CaCO3 formed by reaction between CO2 and CaO and the carbon formed by decomposition of the hydrocarbon are introduced into a fluidized bed 6 for regeneration of a regenerator 5, and heated in the presence of air to regenerate CaO. the CaO is recycled to the CO2 absorber 2, and the gas extracted from the upper part of the regenerator 5 is fed, through a heat exchanger 7, into an air preheater 8, thereby recovering heat energy.
