Title: Radio telephone system
Inventor: FUSE SHOJI
IPC: H04W76/02
Filed: 1988-12-08
Abstract: PURPOSE:To release a wired line immediately into a nontalking state by monitoring a current and a voltage in the wired line in a radio telephone system having plural radio telephone sets moving in plural radio zones. CONSTITUTION:A light emitting diode is inserted in series with a wired line 5(5-1-5-n). Since the light emitting diode is not lighted when the wired line is interrupted, the presence of an interruption fault is informed to a control circuit 11 of a master set 1. Moreover, a reference voltage and a voltage of the wired line 5 are compared by a comparator, a short-circuit fault detection signal is inputted to the control circuit 11 in the occurrence of a short-circuit fault of the wired line 5 to allow the control circuit 11 to recognize the presence of the short-circuit fault. The control circuit 11 receiving a detection signal representing the presence of a short-circuit fault or the presence of an interruption fault opens the wired telephone line into the non-talking state through a switch circuit group.

Filed: 1991-10-30
Abstract: PURPOSE:To increase the processing time for execution of an instruction by applying the different executing ways of instructions based on the detection result that shows a single or plural registers that are designated. CONSTITUTION:A load multiple LM instruction is read into a processor at a stage I, and the existence of the LM instruction is decoded at a stage D. At the same time, a fact whether R1 is equal to R3 or not is also decided at the stage D. If so, the instruction is carried out based on a time chart of R1=R3 shown in a diagram. Meanwhile the LM instruction is carried out based on a time chart of R1=R3 when R1 is not equal to R3. Furthermore the different operations are carried out at the stages A-E between the cases R1=R3 and R1not equal to R3 respectively. Then an operand is pre-fetched out of a memory at the stage A if R1 is equal to R3. Under such conditions, the cycle of the stage E is reduced down to 1/3 for execution of the LM instruction when R1 is equal to R3.

Abstract: PURPOSE:To reduce electrostatic charging noise in a contact electrostatic charging device. CONSTITUTION:An electrostatic charging blade 6 is constituted by laminating a conductive supporting member 6a, an adhesive 6b, a base material layer 6c, a semiconducting resistance layer 6d, and an insulating spacer layer 6e. Many through-holes 6f are made in the spacer layer 6e directly coming in contact with the surface of a photoreceptor 3 in a layer thickness direction so that the resistance layer 6d may be faced to the surface of the photoreceptor 3. When the photoreceptor 3 is rotated in a direction shown by an arrow R3 and voltage is impressed on the blade 6 by a power source 7, the photoreceptor 3 is electrostatically charged through the through-hole 6f of the spacer layer 6e. The material and the constitution of the spacer layer 6e are selected so that frictional force between the spacer layer 6e and the surface of the photoreceptor 3 may be reduced. Thus, the electrostatic charging noise at the time of electrostatic charging is reduced.
