Title: Video signal transmitter
Inventor: ONISHI MASAHIKO
IPC: H04B3/46
Filed: 1990-09-12
Abstract: PURPOSE:To recognize video signal input interruption with simple circuit configuration by transmitting a video signal on the transmission side after clamping it, deciding the interruption of the video signal on the reception side when the signal level of the received video signal is fixed at a clamp level, and informing it. CONSTITUTION:The video signal to be transmitted is clamped by a clamp circuit 1, converted to a digital signal by an A/D conversion circuit 2, converted to an optical signal by an E/O conversion circuit 3 and transmitted to an optical fiber cable 8. A pattern detection circuit 6 monitors the digital signal outputted from the O/E conversion circuit 4, detects the pattern of the digital signal corresponding to the clamp level and decides the video signal input interruption on the transmission side. When there are the continuous patterns of the digital signals corresponding to the clamp level, the pattern detection circuit 6 outputs the input interruption detecting signal of the video signal. Thus, the input interruption of the video signal can be detected without complicating the circuit configuration.

Inventor: YAMAGUCHI JUNKO
IPC: B41M5/392
Filed: 1988-09-26
Abstract: PURPOSE:To perform a printing a large number of times with almost no density reduction by using a polyester oligomer having a specific melt viscosity as a viscosity modifier. CONSTITUTION:The title thermal transfer recording medium contains a wax, a viscosity modifier which melts by heat, but never turns into a low-viscosity liquid, and a coloring agent as main components in a fine porous structure made of a resin formed on a substrate. As the viscosity modifier, a polyester oligomer having a 1000-3000cPs melt viscosity at 100 deg.C is preferable because, for example, it has a good compatibility with various types of waxes and an appropriate adhesion. By incorporating the viscosity modifier in the ratio of 10-15% of the total weight, a melting viscosity suitable for an ink is obtained. In this manner, the thermal transfer recording medium capable of printing a large number of times with almost no density reduction is made available.

Title: Control system for instruction processing order
Inventor: NISHI NAOKI
IPC: G06F9/38
Filed: 1986-10-09
Abstract: PURPOSE:To shorten the processing time with the titled control system by reusing an instruction sequence that is already executed as an instruction group to be applied to an arithmetic part. CONSTITUTION:A read address generating part 25 produces an address to read out successively a stored 1st executing instruction sequence and supplies this sequence to an instruction group selecting part 21. Each instruction of the 1st executing instruction sequence receives a branch information tag and is supplied to an instruction executing order deciding application part 3 to be rearranged here into a 2nd executing instruction sequence. This 2nd sequence is stored in a memory part 41 in place of the 1st sequence by the address supplied from a write address generating part 24. In such a way, the instruction executing order of a group of instruction already executed is reused to decide the instruction executing order. Thus the processing time is shortened with a control system for instruction processing order.

Title: Pc-nc device
Inventor: NINO NORIAKI
IPC: G05B19/05
Filed: 1990-09-11
Abstract: PURPOSE:To simplify the sequence and a starting and completing programs by providing a relay to be exclusively used for detecting movement completion immediately before a drive instruction to a servo motor and detecting the movement completion of the servo motor from the contact signal of the relay. CONSTITUTION:Movement of a servo motor is started by giving a servo motor driving instruction to a driver circuit 8 when the coil signal of an F relay rises. Then the contact signal of the F relay is turned on when the movement of the servo motor is completed. As a result, the F relay makes operations in such a state that the contact signal is delayed from the coil signal by the time spent for the movement of the servo motor. The contact signal turns off when the coil signal is turned off like a timer. The movement completion of an arbitrary servo motor against the driving instruction can be recognized in the form of the contact of an ordinary relay in a sequence process and two timing of the actuation and completion of the servo motor can be handled in the same way as the operations of a timer in the sequence process.
