Title: Manufacture of semiconductor integrated circuit device
Inventor: SASAKI YOSHITAKA
IPC: H01L21/8238
Filed: 1992-10-29
Abstract: PURPOSE:To accurately form twin wells of a semiconductor integrated circuit device in a self-aligned way without giving any damage to the wells. CONSTITUTION:A polycrystalline silicon film 22 which acts as a damage layer is directly formed on the surface of a silicon substrate 21 and phosphorus ions are implanted into the film 22. After the silicon film 22 is removed except the part where N-type wells are formed by using a resist, boron ions are implanted into the surface part of the substrate 21 by using the resist as a mask. Then an N- and P-type wells are formed in a self-aligned way by driving-in phosphorus ions in the silicon film 22 and baron ions in the surface section of the substrate 21 by performing high-temperature treatment. Simultaneously with the formation of the wells, the silicon film 22 is oxidized into a silicon oxide film.

IPC: G08B21/16
Filed: 1992-10-30
Abstract: PURPOSE:To surely detect leakage of gas on the upstream side from a meter. CONSTITUTION:When a gas flow rate detecting means 9 detects a fact that a gas implement is varied from a use state to a non-use state, a time counting means 10 starts time counting. Also, a closed pressure storage means 11 stores a signal of a gas pressure sensor 8 at the time when a gas flow rate stops. Thereafter, the time counting means 10 generates a signal at a first prescribed timing, and by synchronizing with its signal, a gas pressure comparing means 12 fetches the signal of the gas pressure sensor 8, and its signal value and a value stored in the closed pressure storage means 11 are compared. Moreover, at a second prescribed timing based on the signal from the time counting means 10, a gas supply equipment heating means 14 is operated through a heating means control part 15, and gas in a supply equipment is heated. Thus, in the case a pressure difference is not above a prescribed value, it is decided that leakage of gas is generated.

Abstract: PROBLEM TO BE SOLVED: To effectively suppress surface staining by setting the outside diameter of a roller main body at the central part in the axial direction of a cleaning roller to be larger than the outside diameter thereof at the respective ends in the axial direction of the cleaning roller. SOLUTION: The cleaning roller 25 is constituted so that the center axis X1 thereof is positioned almost in parallel with the center axis X2 of a photoreceptor 1 and the outside diameter of the roller main body 25B at the central part in the axial direction of the roller 25 is set to be larger than the outside diameter of the roller main body 25B at the respective end parts in the axial direction of the roller 25. That means, the outside diameter of the roller main body 25B gradually becomes smaller toward the respective end parts from the central area including the central part. Thus, the roller main body 25B is uniformly made to press-contact with the photoreceptor 1 extending over the whole length thereof in the direction of the axis X1.  Therefore, recovering efficiency when toner is recovered to the roller 25 from the photoreceptor 1 and re-attaching efficiency when the toner is attached again to the photoreceptor 1 from the roller 25 are enhanced.
