Title: Duty ratio variable circuit
Inventor: TAKEHIRA MITSUSHI
IPC: H03K5/04
Filed: 1990-10-25
Abstract: PURPOSE:To select the value of duty ratio freely by using the delay of a clock signal for controlling the phase of a data change point in a D flip-flop so as to make the duty ratio of an input signal variable. CONSTITUTION:Clock signal 103 output from a delay circuit 1 is input to a NOR circuit 2, treated together with a signal sent from inverter 5 for NOR operation to prepare a NOR output, and input to an OR circuit 3 as signal 104. In the OR circuit 3 this signal 104 is treated together with a clock signal input from terminal 5 for logical summation to output a signal 105, and input to the clock terminal of D flip-flop 4. Wave form at data output terminal of D flip-flop 4, compared with reference time slot, is varied for a duty ratio of H level to L level by a delay amount tau. Thus, since the present duty ratio variable circuit is a duty variable circuit for a signal that is determined by a clock delay amount in the delay circuit, by setting a delay amount an arbitrary duty ratio can be obtained.

Title: Exchange processing system
Inventor: ITO MORIHIKO
IPC: H04M3/32
Filed: 1989-11-06
Abstract: PURPOSE:To shorten a connection time and to improve a maintenance property by executing all outgoing/incoming processings by transmitting and receiving a PB signal through a speech line. CONSTITUTION:When an outgoing side transmits a PB signal A, an incoming side detects an incoming, and a path is connected to an incoming side terminal. When the incoming side terminal answers, a PB signal B is transmitted from the incoming side, the outgoing side detects the answer of the incoming side and becomes a second connecting state, and a speech can be executed. Subsequently, when the speech is ended, a PB signal C is transmitted from the outgoing side, the incoming side disconnects the path to the incoming side terminal, and also, transmits a PB signal D as a release-guard signal to the outgoing side, and the outgoing side becomes a first connecting state. In such a way, by executing all the outgoing/incoming processings by transmitting and receiving the PB signal, the connection time is shortened.
