Title: Picture element mesh decomposing circuit
Inventor: REON KARUBUIN UIRIAMUZU
IPC: G06T1/60
Filed: 1988-06-07
Abstract: PURPOSE: To decompose image pixels having non-rectangular dots into dots by providing a controller to write a pixel screen value of screen data in existence in an addressed memory location to a 1st latch and to write the address part to a 2nd latch. CONSTITUTION: A memory address latch 56 is programmed to access an address location for addresses of screen values relating to first pixel of a line by a controller 75 at the start of operation. An address location of an address next to that of screen data of a next pixel for dot decomposition is accessed at a half phase θ of a pixel clock pulse 45. In the case of transition to rising of the pulse θ, the address is latched by the latch 56. Simultaneously the accessed address jumps to an address location of a memory 50. The screen value is accessed at a latter half phase of the pulse θ, and at transition of the rising pulse, the screen value is latched by a latch 54. An image pixel in a pixel latch 41 and the screen value in the latch 54 are compared by a comparator 44 and pixels decomposed into dots are outputted to a line 39.

Title: Electrophotographic process
Inventor: HARA KENICHI
IPC: G03G15/16
Filed: 1988-06-08
Abstract: PURPOSE:To facilitate electrification and destaticization in a Carlson process by carrying out the destaticization of a photosensitive body by irradiating the toner transferred surface of a transfer paper from the rear side thereof immediately after a transfer. CONSTITUTION:In the Carlson process, a destaticizing lamp 6 is provided close to a transfer device 5. The lamp 6 is surrounded by a reflecting mirror 9 and brought close to the transfer paper 8 with an about 1mm gap. The quantity of light transmitting of the transfer paper 8 is increased by said lamp 6 together with the reflecting mirror 9. Since a part irradiated with destaticizing light of the transfer paper 8 is closed to a photosensitive drum 1A, the transmitting light does not weaken; therefore the photosensitive drum 1A is effectively destaticized. It takes long time for a part irradiated with destaticizing light on the drum 1A to reach a master charger 2, so that a destaticizing time is enough. In addition, the lamp 6 is remote from the master charger 2, whose side is not reached by the destaticizing light; therefore electrification by the master charger 2 is facilitated.

Title: Afc circuit
Inventor: YANO SETSUO
IPC: H03J7/20
Filed: 1979-10-30
Abstract: PURPOSE:To eliminate the switch operation with every tuning action and thus simplify the operation for an FM radio receiver or the like, by securing an automatic on/off control for the AFC action in accordance with the intensity of the received signal. CONSTITUTION:No output is delivered from the intermediate frequency amplifying circuit in case when a receiver is under the detuning state. Accordingly, the output of the control circuit 8 is approximate to zero. In this case, the reference voltage applied to the input terminal (a) of one side in the switching circuit 7 emerges at the output terminal (d). This voltage is then applied to the variable capacity diode 6 forming the local oscillating circuit 3. Then the tuning action is started to get close to the tuning point, and thus the circuit 7 is switched. As a result, the AFC signal applied to the input terminal (b) is applied to the diode 6.

Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To provide a method by which a thin film transistor having excellent characteristics can be manufactured easily, by forming crystallized films by bringing a plurality of seeds arranged at prescribed intervals into contact with an amorphous semiconductor thin film and, at the same time, forming each channel area of a plurality of thin film transistors in an area where the crystal grain boundary of the crystallized film does not exist. SOLUTION: The silicon thin film of a large grain-size polycrystalline silicon thin film substrate on which an amorphous insulating substrate 2-1, crystallized layers 2-2, and crystal grain boundaries 2-3 are formed (a) is patterned so that the crystallized layers 2-2 may become the central part of an island-like pattern (b). Then, gate oxide films 2-4 and gate electrodes 2-5 are formed so that the electrode 25 may not overlap the crystal boundaries 2-3 (d). When the electrodes 2-5 are formed, the silicon below the electrodes 2-5 forms the completely crystallized layers 2-2 and the layers 2-2 become channel areas (e). Since the channel areas can be formed in crystallized regions except the crystal grain boundaries, the variation of the characteristics of a thin film transistor can be reduced.

Abstract: PURPOSE:To prevent heat exchanger tubes from being deviated to one side by arranging the heat exchanger tubes in a shell pipe concentrically with the shell pipe, disposing an elongate spiral member on the inside of the heat exchanger tubes, and bending simultaneously the shell pipe, the heat exchanger tubes and the spiral member. CONSTITUTION:In a multitubular-type heat exchanger comprising heat exchanger tubes 2 arranged in a shell pipe 1, a spirally shaped rod or tube member is disposed on the inner side of the heat exchanger tubes 2 so as to touch the tubes 2, whereby the tubes 2 in the state of being arranged in contact with the wall of the shell pipe 1 can be bent to form a heat exchanger, without any deviation of the tubes 2 to one side.

With this construction, a liquid to be cooled can be made to flow uniformly through the surroundings of the heat exchanger tubes, and the performance of the heat exchanger can be enhanced.
