Title: Device for winding film
Inventor: TAKEUCHI YASUSHI
IPC: B65H20/32
Filed: 1987-03-25
Abstract: PURPOSE:To attain a control without variation in the tension of a film regardless of presence of eccentricity of a winding core by employing a suction device for sucking the film in the direction to give slack to the film. CONSTITUTION:When the tension of a film 1 decreases, the film 1 between guide roll 2 and 3 slacks due to suction force of a suction device 7, and a position detection device 15 detects the slack to make a control device 14 work to increase the drive force of a core drive device 12. As a result, the rotation of a shaft core 9 is accelerated, the winding up tension of a roll-like film 10, namely the tension of the film 1, increases. When the tension of the film 1 increases on the contrary, the slack of the film 1 between the guide rolls 2 and 3 decreases, the position detection device 15 detects the decrease in the slack to make the control device 14 work to decrease the drive force of the winding core drive device 12. As a result, rotation of the shaft core 9 is decelerated and the winding tension of the roll-like film 10, namely the tension of the film 1, decreases.

Title: Ttl circuit
Inventor: HORIBE YASUSHI
IPC: H03K19/088
Filed: 1990-03-19
Abstract: PURPOSE:To suppress a large undershoot and to reduce ground noise by connecting a resistor to the base terminal of an output transistor(TR) and receiving a base current from a phase division TR via the resistor. CONSTITUTION:The base terminal of an output TR 1 is connected to the emitter of the phase division TR 4 via the resistor 8. In this case, when an input signal VIN reaches an H level from an L level, the phase division TR 4 is turned on from the OFF-state. A base current IB flows to the base terminal of an output TR 1 based on the ON-state of the phase division TR 4. In this case, since the resistor RB is connected to the base, the base current IB is limited, the output TR 1 is turned on and the falling time of an output signal VOUT from the H to the L level is delayed. Thus, a large undershoot is suppressed and the ground noise is reduced.

Title: Display circuit
Inventor: WAKIMOTO KINGO
IPC: G06F3/153
Filed: 1987-03-23
Abstract: PURPOSE:To prevent the flickering produced on a display screen despite the writing and display requests given asynchronously, by providing an access arbitrating circuit to keep an access request given from a CPU during a display period waiting to a display memory. CONSTITUTION:A synchronism control signal 12 for access request given from a display timing generating circuit 3 is set at an H level together with an access given to a display RAM 2 via the circuit 3, and a multiplexer 6 and a display device 21 is working. Under such conditions, an access request signal 8 given from a CPU 1 becomes active. Thus, the access request given from the CPU 1 is kept waiting by an access arbitrating circuit 10. Then, the request kept waiting is validated by the circuit 10 when the display period of the circuit 3 is over. Then, an access is given to the RAM 2 from the CPU 1 for execution of a rewriting job. Thus, the flickering occurring on a display screen can be avoided with no conflict produced between writing and display requests if given asynchronously with each other.

Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To predict overflow of a memory where document image data is stored and to stop carrying a document to stop unnecessary image read operation at the time of predicting the overflow. SOLUTION: An unused storage capacity of the memory where read image data of the document is stored is detected, and an image area corresponding to this detected storage capacity is calculated as an allowable maximum size of the document; and if it is judged by a comparison means (S13) that detected document size data is larger than allowable maximum size data, a signal indicating that copy is impossible is outputted to stop carrying the document by a stop control means (S15). Thus, overflow of the memory is predicted, and carrying of the document is stopped to stop unnecessary image read operation when overflow of the memory is predicted.
