Title: Travelling object communication system
Inventor: ITO SADAO
IPC: H04W64/00
Filed: 1989-04-27
Abstract: PURPOSE:To improve the operation speed by allowing a stationary radio station to control the transmission of a radio wave to a portable radio telephone set in its own service area according to the result of measuring the electric field strength of the radio wave from the portable telephone set. CONSTITUTION:In the case of setting a radio line, the position is registered by a portable telephone set PTEL to check a stationary radio station FRS able to make service and informing the resulting to the station FRS. When a call comes, the station FRS sends a notice signal. The telephone set PTEL sends a position registration command. The station FRS measures the electric field strength of a position registration request signal and when it is judged that the telephone set PTEL does not exists its own service available area, no radio wave is sent but the station keeps standby state. Moreover, when the station FRS judges that the telephone set PTEL exists is own service area, the station sends a required radio wave for a prescribed time. Then the transmission is continued or stopped depending on the occurrence state of the communication occurred in the time.

Filed: 1988-04-28
Abstract: PURPOSE:To prevent the rupture or the wrinkle of a sheet from being generated by manufacturing a roller at a side not being brought into contact with an unfixed toner image out of a pair of rollers by a material whose surface is not deformed by the welding force of a pressure spring, and driving the roller rotatably via a driving mechanism. CONSTITUTION:The roller at the side not being brought into contact with the unfixed toner image out of the pair of rollers 1 and 2 is set as the pressure roller 2. And the pressure roller 2 is manufactured by the material whose surface is not deformed by the welding force of the pressure spring 3, for example, aluminum, etc., and it is driven rotatably by the driving mechanism. In other words, since the side of the roller manufactured by the material whose surface is not deformed by the welding pressure of the pressure spring is driven rotatably, it is possible to feed the roller synchronizing with feed rollers provided at the front and rear of a fixing unit and also, to carry the roller at the same feed pitch, and to prevent the rupture or the wrinkle of the sheet from being generated.

Abstract: PURPOSE:To decrease the area of a TFT occupying in one picture element while suppressing the fluctuation of the capacity between a source and gate within the plane of a display region to a lower level by devising the shapes of a source electrode and drain electrode. CONSTITUTION:The thin-film transistor (TFT) 20 is constituted of the gate electrode 22 integral with a line selection line 21, the drain electrode 24 integral with a row selection line 23, the source electrode 26 connected to a display electrode 25, and a semiconductor layer 27. The drain electrode 24 is provided on both sides of the source electrode 26 in the direction perpendicular to a longitudinal direction 28 of the line selection line 21. The drain electrode 24 is made into a shape having one recessed part 29, for example, a U shape. The source electrode 26 has a shape inserted into the recessed part 29. The fluctuation in the gate-source capacity occurring in the alignment error in the longitudinal direction 28 is decreased in this way and the effective utilization of the outer peripheral part of the source electrode 26 in forming a channel part is possible. The size of the TFT 20 is thus reduced.

Filed: 1981-07-07
Abstract: PURPOSE:To enable dust collection in good efficiency, by a method wherein pulse generation applied to a discharge electrode is carried out by a switching element and the pulse width thereof is determined by circuit constants of the reactance and the capacitance of a pulse voltage boosting transformer.

Abstract: PURPOSE:To stably perform the supply of a power source, by selecting one of the detection voltages of two kinds of power source different in charge capacity corresponding to the voltage detection signal of a timepiece driving power source. CONSTITUTION:When the first condenser 4 low in charge capacity among the condensers of two kinds of power sources different in charge capacity charged by the electromotive forces from first and second solar cells 6, 8 is used as the power source of a time-piece driving circuit 3, the voltage detection signal P30 from a voltage detection circuit 30 is usually an L-level and control is applied to a detection signal generating means 43 so that a detection voltage selection means 42 selects the charge voltage of the condenser 4 as detection voltage. When a condenser 7 having high charge capacity is connected as the power source of the circuit 3 and the voltage applied to the circuit 3 is higher than a prescribed voltage level, an overcharge detection signal P43 of an H-level is outputted from the means 43 and a discharge circuit 50 performs discharge operation and, when voltage drops by discharge, the signal P43 changes from the H-level to an L-level and the circuit 50 is turned OFF to stop discharge. Therefore, by changing over the detection voltage of an overcharge detection circuit 41 corresponding to the prescribed voltage level in each state, the stable supply of a power source is performed.
