Title: Image forming device
Inventor: KUBO TAKAHIRO
IPC: G03G21/00
Filed: 1993-08-03
Abstract: PURPOSE:To prevent oil attached on a transfer material after an image is fixed on a front surface from being attached on a photoreceptor drum through a transfer drum when the image is formed on a rear surface as for an image forming device transferring toner images on the plural transfer materials simulatenously carried by the transfer drum. CONSTITUTION:In the case that the toner images of magenta M, cyan C, yellow Y and black Bk are transferred on the continuous odd number-sheets of transfer materials by simultaneously carrying two transfer material by the transfer drum, the transfer of two sheets, two sheets ... one sheet is conventionally executed like a figure (c), that means, the transfer of one sheet is executed last. Therefore, the oil attached on the transfer material at a fixing time is retained at the part of the transfer drum where the transfer material is not carried at the last transfer occasion and attached on the photoreceptor drum 1 and a hand. Then, the transfer of one sheet, two sheets ...two sheets is executed like a figure (a), that means, the transfer of one sheet is executed at first. Thus, the oil on the transfer material is not attached at the part where the transfer material is not carried at first. Since the part where the transfer material is wanted to be carried is not made thereafter until a transfer sheet cleaner is actuated, the oil is not transferred and attached on the drum 1 from the transfer drum.

IPC: H01J29/28
Filed: 1982-12-01
Abstract: PURPOSE:To prevent the X-rays generated inside of a tube from leaking outside of the tube while improving the picture brightness by forming a silver metal layer and a silver sulfide layer on the beam scanning side of a phosphor screen reproducing an image picture. CONSTITUTION:A metal layer 17 mainly consisting of silver is formed on the electron beam scanning side of a phosphor scree 5 formed inside of a panel 2 of a cathode-ray tube while further outside thereof, a silver sulfied layer 18 having a thermal radiation characteristic close to a complete black substance is formed. And electron beams are made to pass through a shadow mask 9, which is a color selective mechanism, in order to generate fluorescence on the phosphor screen 5 while further being made to pass the silver sulfide layer 18 and the silver metal layer 17. Accordingly, by changing the metal layer 17 from the former alminium to silver sulfide, the X-rays are efficiently prevented from leaking outside of the tube while improving the brightness of the colors of blue, green and red respectively as well as the brightness of the pictures.

Filed: 1987-08-26
Abstract: PURPOSE:To check whether wiring is correctly set or not before automatic adjustment of a power factor by providing an operation test means which successively makes and breaks capacitors at intervals of a certain time by a prescribed signal from a setting means. CONSTITUTION:An arithmetic processing means 102 compares the reactive component of an electric circuit detected by a reactive component detecting means 101 with the making point level or the breaking point level where the power factor adjustment value is set by arithmetic data inputted by a setting means 105. The arithmetic processing means 102 outputs a making signal if the power factor adjustment value is lower than the making point level, and the means 102 outputs a breaking signal if it exceeds the breaking level. When the arithmetic processing means 102 outputs the making signal or the breaking signal, a control means 50 performs the making or breaking operation of capacitors 62a-62c to the electric circuit. An operation test means 108 successively makes and breaks all capacitors at intervals of a certain time at the time of input from the setting means 105. Thus, it is previously checked whether wiring is correctly set or not.
