Title: Cleaning device of electrophotographic copying machine
Inventor: TSUKAHARA SUMIO
IPC: G03G21/00
Filed: 1982-07-24
Abstract: PURPOSE:To simplify a driving mechanism and also to prevent damage of the surface of a photoreceptor, by utilizing an attraction/repulsion operation of a magnet member for a driving mechanism of a sealing device. CONSTITUTION:The driving mechanism C is formed by the magnet member 10 provided on a blade 8 of the sealing device B and a driving magnet member 11 provided on a position for generating an attraction/repulsion magnetic field with the magnet member 10. This driving magnet member 11 consists of a pair of the magnet members 13a, 13b having each opposite polarity. In this state, when the driving member 11 is rotated, the attraction/repulsion operation is generated in the driving mechanism C. As a result, the blade 8 is rotated, and a plate-like collecting member 4 is made to press-contact and is separated to and from the surface of the photoreceptor 1. In this way, transfer of pressure force to the surface of the photoreceptor can be executed by non-contact, therefore, damage of the surface of the photoreceptor is prevented and also the driving mechanism can be simplified.

Title: Gas rate sensor
Inventor: TAKAHASHI FUMITAKA
IPC: G01C19/00
Filed: 1987-05-27
Abstract: PURPOSE:To improve temperature rise characteristics and temperature adjustment accuracy based upon a heater wire by providing a plane part in the outer peripheral surface of a casing, arranging a cover which contains a thermistor, and forming the heater wire so that its section is rectangular. CONSTITUTION:The casing 11 is provided with the plane part 12 and the metallic cover 13 which contains the thermistor is arranged there. The abutting surface between the plane part 12 of the casing 11 and cover 13 is plane, so the contact area is large and the heat resistance is small. Therefore, the advanced heating of the thermistor by direct heat from the heater wire 14 is prevented. The heater wire 14 is wound around the cover 13, so temperature variation causing by the ON-OFF operation of the heater wire 14 is detected quick to improve the temperature rise characteristics and temperature control accuracy. Further, the heater 14 has the section of the rectangular shape and the contact area on the side of the casing 11 is large, so the mutual heat conductivity among the heater 14, thermistor and casing 11 is excellent and the time lag of temperature is reduced. Therefore, influence of variation in outside temperature upon a sensor main body is eliminated and high detection accuracy is obtained.

Title: Compiling system for compressed source program
Inventor: SHOJI SHINICHI
IPC: G06F9/44
Filed: 1988-05-27
Abstract: PURPOSE:To shorten the compiling time by directly taking a compressed source program as the object of word and phrase analysis without decoding (expanding) this program and increasing the skip read speed of blank characters. CONSTITUTION:The compressed source program includes an 8-bit control code, and upper four bits indicate the number of characters other than blacks, and lower four bits indicate the number of following blank characters. On the compiler side, a blank is handled as a delimiter character, and one blank as well as continuous blanks have the same function. Consequently, a blank skip read processing part is provided before a word and phrase analyzing part of the compiler to skip over excess blanks at the time of reading, and at this time, a one-character input part is executed for each one character. Thus, 10 continuous blanks are substituted with the one-byte control code in the system where the compressed source program is directly taken as the object of word and phrase analysis (one-character input), and it is sufficient if the one-character input part 5 is executed once, and the compiling time is shortened.

Filed: 1985-06-13
Abstract: PURPOSE:To prevent deterioration of picture quality because of flickering to eyes due to mixture of a high-order and a low-order coded parameters by providing a shift register and an OR circuit to which an output signal of each stage and a parameter signal are inputted directly so as to lock a parameter signal for a prescribed time. CONSTITUTION:In a normal mode holding circuit 1, the parameter signal is inputted to the shift register 2 and an n-input OR circuit 3. The shift register 2 uses a frame lock signal to shift the parameter signal, which is inputted to the n-input OR circuit 3. When '1' exists in the input, the n-input OR circuit holds '1' and outputs it. Thus, when the parameter signal changes from '1' to a '0', '1' is held for a prescribed time by the shift register 2 and the n-input OR circuit 3. Then the output whose coded parameter change form high to low-order is guarded by a timer circuit 4 is inputted to the normal mode holding circuit 1, and the output whose coded parameter change from low to high-order is guarded by the normal mode holding circuit 1 is inputted to a OR circuit 5.
