Title: Image forming device
Inventor: SAITO RIE
IPC: G03G21/14
Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To prevent a rotating body from being damaged and to secure safety by making the amount of an unfixed image transferred from recording material to the rotating body equal to the transfer amount of the unfixed image in the midst of ordinary image forming when a recording material existence detection means detects the recording material after the interruption of image forming operation. SOLUTION: In the case of stopping copying operation by detecting any abnormality in a device main body in the midst of copying operation, the existence of the recording material is detected by a sensor S detecting the existence of the recording material near a fixing roller 51. When the recording material existence sensor S detects that the recording material is in the vicinity of the roller 51, power sources for the halogen heater 56 of the roller 51 and the halogen heater 57 of a pressure roller 52 are not turned off but the temperature of both heaters 56 and 57 is controlled in the vicinity of the softening point of toner. Then, the toner exists on the recording material or near the roller 51 in a softened state, and the toner is melted in the same state as the ordinary fixed state and is not offset to the roller 51, so that releasing property is kept excellent.

Filed: 1988-09-20
Abstract: PURPOSE:To always attain proper dark time correction by providing an A/D converter digitizing an output signal of a noneffective picture element area of a line sensor and a signal latch means latching its output signal and using the said output signal as a reference signal. CONSTITUTION:An effective picture signal and a black level reference signal latched in sample-and-hold circuits 34a, 34b are extracted sequentially respectively and converted into a digital signal by A/D converters 11a, 11b. Both the signals digitized are inputted respectively to latch circuits 12a, 12b, where the signal is latched. Then both the signals are inputted to an arithmetic circuit and the black reference signal is subtracted from the effective picture element signal. Thus, a picture signal subject to dark time correction is generated. Since the black level reference signal is digitized and latched in the latch circuit 12b, the signal level even being latched over a long time is not changed and the dark time correction using the always accurate black level reference signal is attained.

Inventor: MANJO MINORU
IPC: H02P9/00
Filed: 1989-09-11
Abstract: PURPOSE:To detect abnormalities of a detection system of the quantities of operating state of a synchronous machine and a generator accurately by judging whether two quantities of equivalent state based on the first quantity of state detected from the armature output end of the generator and on the second quantity of state detected from the input end thereof satisfy a given correlation or not. CONSTITUTION:When the protective fuse 12 for TP 11 is blown out a detected voltage inputted to an internally induced voltage operation means 21 is considerably small so that the absolute value ¦E¦ of the internally induced voltage E of a generator 1 outputted from the internally induced voltage operation means 22 also takes a very small value and an abnormality judging means 23 operates to switch a change-over switch 15 to a field current constant control system (standby system). Thus, the generator 1 is controlled according to a reference field current IRFE determined by a setter 19.

Filed: 1991-09-17
Abstract: PURPOSE:To increase the rate of polymerization of the resin of an unexposed section with a photosensitive material so that a precise pattern can be formed with high accuracy by again performing exposure by using a mask pattern after the photosensitive material contained in a resist immediately below the mask pattern is polymerized with the resin by irradiating the entire surface of the pattern with ultraviolet rays after the pattern is exposed. CONSTITUTION:A resist 2 containing a photosensitive material and resin which can be polymerized with the material is formed on the surface of a wafer 1. After forming the resist 2, the resist 2 is exposed at such energy that no diffracted light goes round to the part of the resist 2 immediately below a prescribed mask pattern by using the mask pattern. Then the photosensitive material and resin contained in the resist 2 immediately below the mask pattern are polymerized with each other by irradiating the entire surface of the wafer on which the resist 2 is formed with ultraviolet rays having a prescribed wavelength. After polymerization, the surface of the wafer 1 is again exposed by using the mask pattern. Then a desired pattern is obtained by, for example, eluting the resist 2 in the exposed section with an alkaline developing solution.
