Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To effectively remove soil on a transfer-material carrying means in order to clean the transfer-material carrying means which carries a transfer material to an image carrier. SOLUTION: The image forming device is equipped with a transfer belt 14 for carrying the transfer paper to a photoreceptor drum 1 being the image carrier, and a cleaning blade 15 for removing sticking matter on the transfer belt 14 by sliding against the surface of the transfer belt 14.

Title: Manufacture of semiconductor device
Inventor: HIRAO HIDEJI
IPC: H01L21/768
Filed: 1993-06-21
Abstract: PURPOSE:To deposit a flat layer insulating film without dissolving an aluminum wiring by a method wherein the aluminum wiring is covered with a material film which is insoluble in a hydrofluoric acid, to form a water-repellent material film on the upper surface of the aluminum wiring. CONSTITUTION:A silicon dioxide (SiO2) film is deposited by a liquid growth method, using a saturated or supersaturated aqueous solution obtained by dissolving silicon dioxide powder in a hexafluorosilicic acid. At this time, a tungsten (W) film 6 and an aluminum fluoride (AlF3) film are formed on the sidewalls of an aluminum wiring. Both of these substance films are insoluble in a hydrofluoric acid (HF) which is produced at the time of a liquid growth. Moreover, as a photoresist 5 is insoluble in the hydrofluoric acid (HF) and hydrophobic, the SiO2 film deposited by the liquid growth is not deposited on the aluminum wiring. Accordingly, the SiO2 film is uniformly deposited on an insulating film other than the aluminum wiring 4 up to the film thickness of the wiring 4.

Abstract: PURPOSE:To shorten a time in which the occurrence of abnormality is detected by a host station and to suppress a damage to a minimum by a method wherein a state change control line (COS line) is positioned in juxtaposition to a transmis sion circuit, and during emergency of the COS line, the transmission speed of data is increased. CONSTITUTION:When abnormality occurs to a member station, the member station turns on a COS line 4, and reports a host station 1 at a high speed through the COS line 4 separately from a normal control circuit 3 that a state change (COS) occurs to the host station 1. When the host station 1 detects COS, global polling is rapidly transmitted to all the member stations. All the member stations receiving global polling respond, in order, the address of a self-state and response data in which abnormality occurs or not, and this causes the host station to receive the response data to detect a station to which abnormality occurs. The host station starts an abnormality processing program, performs polling in priority to the station to which abnormality occurs, and receives trouble information data as response. This constitution enables rapid processing of abnormality in response to a trouble state.
