Title: Radio communication equipment
Inventor: NAKAMURA TAKAHARU
IPC: H04W36/00
Filed: 1993-02-05
Abstract: PURPOSE:To extremely improve the communication quality by preventing effectively the breaks and mixture of communication signals caused by the hand-off actions given in a communication mode. CONSTITUTION:In general, a telephone call is started in the voices udttered alyernately by the calling and called subscribers, and an instant when both subscribers utter the voices at a time is rare. This fact is true also in the data communication. So a radio communication equipment 100 is constructed based on that fact. That is, the equipment 100 includes a radio communication part 1, a transmission detecting part 2, and a control part 3. The part 3 switches the receiving frequency to f6 from f2 when the channels are switched in a communication mode due to a fact a station 300 of the opposite party side is not in a transmission mode while its own station is kept in a transmission mode. When the transmission mode of its own station is over, the part 3 switches the receiving frequency to f5 from f1. In such a way, the communication is never affected. However the part 3 forcibly switches the transmitting or receiving frequency when a timer means 5 has a time-out state. In such a constitution, the communication is never affected even in a cellular communication system.

Filed: 1986-01-30
Abstract: PURPOSE:To increase remarkably the number of sheets to be processed under maintenance free status by forming a cleaning member driving means for receiving a cleaning signal from an electrostatic discharge line dirt detecting means and driving a discharge line cleaning member. CONSTITUTION:A light emitting element 17 and a light sensitive element 18 which are opposed through a filter 16 detect the degree of dirt due to the adsorption of attachment from the discharge line by the filter, and when light emitted from the element 17 can not be transmitted through the filter 16, a filter dirt sensor 19 sends a signal to an arithmetic part 26. Consequently, a control part 27 displays the dirty state of the filter 16 on a display part 29 as a message and the operator knows the necessity of replacement of the filter 16 by observing the displayed message. The surface of the discharge line 7 is always cleaned and the attachment can be removed by repeating said control. Consequently, influence due to the dirt of the discharge line is not generated on an image, maintenance free can be attained and the number of sheets resisting against the dirt of the discharge line can be remarkably increased as compared to the current case.
