Title: Small-sized electrophotographic copying machine
Inventor: SATOU MASAMICHI
IPC: G03G21/06
Filed: 1983-08-29
Abstract: PURPOSE:To obtain an image of high quality by removing a charge generated in an original support or photosensitive body, and moving the original and support relatively and smoothly. CONSTITUTION:An electrostatic discharging member 30 is provided where a charge is generated by friction. The discharging member 30 is not limited to a discharging brush 30a and uses a roller 30b made of conductive soft rubber or sponge, and this is allowed to abut on the original support 2. Consequently, even if an electrostatic charge is generated on the surface of the original support 2 in a copying process owing to the friction of rolls 3a and 3b and the friction against the original 1, this charge is removed with the discharging brush 30a which abuts on the original support 2. Consequently, there is no electrostatic charging attraction occurring between the original support 2 and original surface, so the original support 2 is moved smmothly and discharge is never caused. Thus, the destruction of an electrostatic latent image due to discharging is prevented and the picture quality never deteriorates.

Inventor: OTANI SHINICHI
IPC: D06B15/02
Filed: 1985-07-15
Abstract: PURPOSE:To increase the water absorbing speed of a water removing roller for a water containing sheet etc. greatly by making at least one of the drum component members in the form of a water absorbing roller and by giving a higher absorptivity to its core part than the surface course. CONSTITUTION:This wafer removing roller is made in such a construction that a wafer absorptive member 11 of paper etc. is formed cylindrical over a core 12 consisting of plastics etc. This water absorptive member on paper basis 11 is composed of a surface course made of a water absorptive material 111 with higher fiber density and a core part 12 made of an absorptive material with lower fiber density and greater water absorbing capacity. This will give the roller a water absorbing speed 3-5 times as high as that of a conventional type, and thus the roller is suitable for continuous high-speed processing and capable of processing in a quantity 3-5 times as great as the saturated processing unit of a conventional one.

Title: Data communication system
Inventor: ISHIKAWA HARUO
IPC: H04L27/00
Filed: 1989-06-19
Abstract: PURPOSE:To normally receive a signal even at the time of the noise level higher than a certain value by resetting a detector to perform the next receiving operation at the time when reception of a synchronizing character is not detected within a certain time regardless of detection of the reception level higher than a certain value. CONSTITUTION:When a significant signal is inputted to a reception control part 16 from a detector 13 which detects the reception level higher than the certain value, the control part 16 operates a time counting function part 15 to wait for input of a significant signal from a detector 14 which detects reception of the synchronizing character. If a certain time is counted in the time counting function part 15 before the input of the significant signal from this detector 14, a function part 17 to reset detection of the reception level higher than the certain value is operated. Then, the detector 13 which detects the reception level higher than the certain value is reset to prepare for the next receiving operation. Thus, normal reception is possible even in noisy circumstances.

Title: Capillary electrophoresis system and separation of sample component
Inventor: GIYARII BII GOODON
IPC: G01N27/447
Filed: 1994-06-15
Abstract: PURPOSE: To separate a sample component with high accuracy by simple constitution by switching voltage to be impressed on plural electrode points arranged in a separating passage. CONSTITUTION: Three electrode points 2E1, 2E2 and 2E3 are arranged in a separating passage 208. A distributing means 204 impresses positive voltage on the electrode point 2E1, and negative voltage on the electrode point 2E2, and establishes a separating electric field 2F1. A sample is injected into a capillary 206 under this condition. The sample is attracted toward the electrode point 2E2 by the electric field 2F1, and separation of sample components 2S1 and 2S2 is started. When the component 2S2 reaches a transition point 2TA, the distributing means 204 switches an electric field to an electric field 2F2 from the electric field 2F1 and to an electric field 2F3 in the next place by impressing negative voltage on the electrode point 2E3.  Under the influence of the comparatively strong electric field 2F3, the component 2S1 moves further to the downstream side toward the electrode point 2E3 from the electrode point 2E2. Next, a detector 210 identifies and quantitatively determines these when the component 2S1 and the other sample component pass through a detecting point 2D1.

Title: Video signal processor
Inventor: TAKEI MASAHIRO
IPC: H04N11/22
Filed: 1984-07-27
Abstract: PURPOSE:To attain the line synchronization of a line sequential signal without an error by specifying a phase inversion timing of a line synchronization control signal. CONSTITUTION:An output of a retriggarable monostable multivibrator 29 is also supplied to a control circuit 35. The output of the vibrator 29 is detected by the control circuit 35, the number of falling times, that is, the number of discontinuous points, is counted. When the number (n) is not ''1'', the judgement is made that the pure discontinuous point does not exists. Under this judgement, a discontinuous point will not be detected anymore, and the phase inversion is made at a pulse (c). If the number (n) is ''1'', the point is judged to be a discontinuous point, and afterwards the phase inversion of a switching control signal is controlled according to said point. Since the phase of the line synchronization control signal can be securely inverted at the phase discontinuous point of the line sequential signal, the line sequential signal can be line-synchronized without an error.

In this regard, voltage appearing in the collector of the transistor Q1 becomes a value which is almost equal to base voltage of the transistor Q2 because the base-emitter voltage of the transistor Q2 and the voltage of both ends of the diode D4 are equal.

Filed: 1987-06-24
Abstract: PURPOSE: To constitute a delay circuit inside an LSI, by using a gate, which is also used as a delay element, instead of a tap switching mechanism and supplying a gate control signal to the gate.  
     CONSTITUTION: In block 1, a control signal B is set to '0' with the shifting clock C of a shift register 9 and both output data QA and QB of the register 9 are '0' and, when the both output data are decoded by a decoding circuit 10, an output is made to the terminal 0 of the circuit 10. As a result, a gate control signal E becomes enable and a gate 5 is set to a signal passing state. Therefore, a signal D which is obtained by delaying a signal A by means of gates 1∼3 and 5 is outputted from the gate 5. In block 2, the control signal B is '1' and the shift register 9 is set to '1' by the shift clock C. Then the output data QA is '1' and QB is '0' and an output is made to the terminal 1 of the decoding circuit 10. As a result, a gate control signal G becomes enable and the signal D which is obtained by delaying the signal A at gates 1 and 7 is outputted. Therefore, the delaying time or phase of the signal can be controlled with a signal from the outside.
