Title: Destaticzing method of electrophotographic device
Inventor: AIZAWA HIDEO
IPC: G03G21/06
Filed: 1984-07-31
Abstract: PURPOSE:To prevent a part on a photosensitive substance which corresponds to the leading end part of transfer paper from defective cleaning by switching a destaticized current value of a destaticizer at the destaticization of a part corresponding to the leading end part and at the destaticization of a part corresponding to a part other than the leading end part. CONSTITUTION:A controller 26 repeatedly counts up a clock pulse and a sink pulse generated from a pulse generating part every rotation of a photosensitive drum 1 by respective counters to control power packs 23, 24 on the basis of the counted values. A corona discharger 21 for destaticization is driven only by the power pack 23 when a part on the drum 1 which corresponds to the leading end part of the transfer paper passes and a small current of 30-40muA flows to destaticize the corresponding part. Consequently, the cleaning efficiency of the cleaning device 22 to the part is improved and defective cleaning is removed.

IPC: H04N1/04
Filed: 1986-07-08
Abstract: PURPOSE:To obtain a printing picture nearly the same as a printing picture of a facsimile equipment by changing the moving speed of a medium to be recorded depending whether a conversion means converting a split data is operated or not. CONSTITUTION:In receiving a picture data from a facsimile equipment at a sender side to a MODEM 19, an expansion control section 20 converts (expands), e.g., a 4-bit picture data into a 6-bit data. In storing the data expanded in a main scanning direction in a dot pattern memory 22, a data is read sequentially to drive circuits 12-1, 12-2 to expose the photosensitive face. The turning speed of the photosensitive drum is kept faster than that at the printer mode in order to decrease the dot density in a subscanning direction. Thus, the picture printed by the printer is nearly the same as the picture printed by a conventional facsimile equipment, and the picture is neither contracted nor deformed.

Abstract: PURPOSE:To accurately measure the relation between the load and the deformation of a material set in a special atmosphere, such as the atmosphere in a furnace, etc., by detecting the load with a moving probe whenever the probe comes into contact with reference points set on a frame or at part of a weight. CONSTITUTION:When a probe 10 is driven by a driving mechanism 8, the load value detected by means of a load cell 9 varies whenever the probe 10 comes into contact with reference points P on a frame 3 or a reference point Q on a weight 5 while the probe 10 is moved. A microcomputer 12 inputs a load value signal (a) and, whenever the load value varies, switches the driving direction of a driving mechanism 8 by outputting a control signal (c). Therefore, the probe 10 is moved between the points P on the frame 3 and point Q on the weight 5. As the probe 10 is moved, a magnescale 11 detects the displacement of the upper end section 10a of the probe 10 and outputs a detected displacement signal (b) to the microcomputer 12.
