    摘要: In a communication system between a road and a vehicle, communicating between a plurality of road communication stations arranged in a cell and a vehicle-mounted mobile station within the cell, a vehicle-mounted transmitting equipment, in which communication is not interrupted even when a received frequency varies due to the Doppler effect and which performs stable communication, is realized. A transmitting antenna 36a having a directivity in the running direction of the vehicle and a transmitting antenna 36b having a directivity opposite to the running direction of the vehicle are arranged. An offset for increasing a frequency is provided for a radio wave emitted from the antenna 36a while an offset for lowering a frequency is provided for a radio wave emitted from the antenna 36b. The variation in the received frequency depending on the Doppler shift is reduced for the vehicle-mounted receiving device to facilitate automatic frequency control (AFC), thereby reducing degradation in the quality of data after demodulation.

    摘要: A sheet post-processing device of the present invention conducts post processing on sheets and then ejects the sheets on an offset tray. Upon the ejection, the sheets are sorted by a sorting drive section reciprocating the offset tray horizontally. The sheets are aligned at the trailing edges thereof by a plurality of sheet edge stopper columns erected freely rotatable. The offset tray is moved vertically along the sheet edge stopper columns by, for example, a lifting and lowering motor. Friction rollers are provided as linking means for rotating the sheet edge stopper columns in accordance with a horizontal movement of the offset tray. As to the horizontal movement and a vertical movement of the offset tray, the friction rollers transmit a driving force to the sheet edge stopper columns only when the offset tray is moved horizontally. Consequently, the stack disturbance of the sheets can be prevented both when the offset tray is moved horizontally and when the offset tray is moved vertically.

    摘要: The thin film transistor comprises source and drain regions, a channel forming region formed between the source and drain regions, a first (main) gate for turning on or off the transistor, and in particular at least one second (sub-) gate for reducing turn-off leakage current. When the n-channel transistor is turned off, for example, a negative voltage is applied to the main gate to form a p-channel layer in the channel forming region under the main gate and a positive voltage is applied to the subgate to form an n-channel layer in the channel forming region under the subgate, for instance, so that a pn junction can be formed between under the main gate and the subgate to reduce the turn-off leakage current. The above-mentioned disclosure can be clearly applied to p-channel transistors. Further, the above four-terminal transistor can be simply modified to a three-terminal transistor by connecting the main gate to the subgate via a diode or a capacitor or by directly connecting the drain region to the subgate. Further, the above three-terminal transistor can be manufactured in accordance with only the ordinary device manufacturing process.
