Title: Store and forward service input system
Inventor: SAITO KAZUHITO
IPC: H04N1/32
Filed: 1985-12-20
Abstract: PURPOSE:To reduce the labor of an operator by storing the line number of a terminal equipment, which requests the store and forward service, in a store and forward exchange if the service is impossible because of overflow of a memory or the like and calling this line number to perform the requested store and forward service when the service is possible. CONSTITUTION:When either one of FCX lines L1-Lm of the store and forward exchange 10 is called from the FAX of each of terminal equipments F1-Fn, the FCX returns ID to the FAX, and FAX receives this ID to transmit a service request command, the information of its own station, and the destination information. If the memory of the FCX or the like is overflowed or busy, a wait request is transmitted, and the FAX enters into the wait state by DCN (line disconnection). After the store and forward exchange is released from the busy state, the polling of the suspended service request is performed, and the line number of the transmission source is found and is called. When the FAX returns ID and the status in response to this call, the FAX transmits a signal indicating that communication is possible and is operated in accordance with the stored service command.

Abstract: PROBLEM TO BE SOLVED: To mitigate the shock when a tip passes through a unit roll by detecting the tip of a traveling strip and the tip of a strip coiled by a mandrel, and tracing the tip position to control the unit roll. SOLUTION: A position detecting sensor 4 installed on the outlet side of a pinch roll 2 detects the position of the tip of a traveling strip S. A tracking sensor 6 starts the trace and detection of the tip position of the strip S. When it is confirmed that the tip of the strip S passes the position of a first unit roll 3a, the roll 3a is switched from the fixed position control to the fixed pressure control. A position detecting sensor 5 installed on the outlet side of a second unit roll 3b detects the tip position of the strip S coiled by a mandrel 1. The sensor 6 is corrected by the detected signal of the sensors 4, 5. The second and third unit rolls 3b, 3c are similarly switched from the fixed position control to the fixed pressure control. The unit roll control is switched at correct timing.

Title: Motor controller
Inventor: KATSURAGI TETSUYA
IPC: H02P7/29
Filed: 1990-10-29
Abstract: PURPOSE:To enlarge controllable rotational speed range with high accuracy by varying the width and the amplitude of a pulse for feeding power to a motor thereby controlling the rotation of the motor. CONSTITUTION:A controller 1 compares an external speed command signal with a speed signal fed from a speed detecting means 5a for detecting the speed of a motor 5 and then selects optimal pulse voltage and pulse width for equalizing the rotational speed of the motor 5 and a commanded speed. In order to equalize the speeds, a voltage command signal is fed to a variable power supply 2 while simultaneously a pulse width command signal is fed to a variable pulse generating circuit 3. Power fed from the variable power supply 2 receiving the voltage command signal is switched at a driving pulse generating circuit 4 based on a pulse fed from the variable pulse generating circuit 3 and thus switched power is fed to a DC motor 5. Since the driving pulse to be fed to the DC motor 5 varies in width and voltage, driving range of the DC motor 5 is enlarged.
