Title: Duty converting circuit
Inventor: TEZUKA HIDEHARU
IPC: H03K5/04
Filed: 1982-01-28
Abstract: PURPOSE:To set the duty of an output pulse in response to the relative level between the currents of two current sources, by constituting a circuit with a small number of elements such as transistors, capacitors, resistances, etc. CONSTITUTION:When the potential of an input terminal 13 is equal to the positive voltage, a transistor (TR) Q4 is turned on with the collector potential V1 set at an earth level. With discharge of a capacitor C, the base potential V2 of a TRQ5 is lowered and then turned off. While a TRQ6 is turned on. Therefore the potential of an output pulse p0 obtained in a period t2 during which TRs Q5 and Q6 are turned off and on respectively is equal to the divided voltages of resistances R4 and R5. Then the potential V2 rises up by a current I2 to turn on the TRQ5. At the same time, an output terminal 14 is set at about earth potential, and the TRQ6 is turned off. The terminal 13 is set at an earth potential during a period T2, and the TRQ4 is turned off. When both TRs Q4 and Q6 are turned off, the capacitor C is charged by a current I1 and backward to the above-mentioned direction. Thus the potential V1 increases. The above-mentioned operation is carried out with application of the next pulse. Then it is possible to set the duty in response to the relative level between the currents I1 and I2.

Title: Electronic equipment
Inventor: YOSHIDA HIROKI
IPC: H04B7/26
Filed: 1989-01-20
Abstract: PURPOSE:To eliminate a waste of the current consumption of an integrated circuit while maintaining operation matching with an external circuit by controlling the supply of a necessary and sufficient source voltage from a constant voltage power circuit to the integrated circuit according to whether bus data is outputted by the integrated circuit or not. CONSTITUTION:When detecting an IC 11 neither inputting nor outputting bus data to and from an external circuit 12 from an input bus detection signal or output bus detection signal, a source voltage switching circuit 15 performs switching and control so as to supply the minimum operation guarantee voltage as the source voltage to the IC 11. Further, the source voltage switching circuit 15 performs switching control so as to supply a standard rated voltage as the source voltage to the IC 11 when the IC 11 detects the input of the data bus from the external circuit 12 from the input bus detection signal. Then the bus detecting circuit 18 which sends the input bus detection signal performs the detection before the bus data arrives at the IC 11 from the external circuit 12, so the IC 11 already enters its normal start state when the data bus arrives at the IC 11 from the external circuit 12. Therefore, the IC 11 inputs the bus data without any trouble such as 'head cutting'.
