Title: Watch dog counter
Inventor: KOGA TAKATOSHI
IPC: G06F11/30
Filed: 1987-07-28
Abstract: PURPOSE:To escape from an infinite loop by outputting a subroutine branching instruction requesting signal when the number of times of generation of a control signal to a stack pointer is counted by the prescribed number of times. CONSTITUTION:This counter is composed of a stack pointer 101 to generate an address for the value of a program counter to escape at the time of executing a sub-routine branching instruction and a counter 106 to output the sub-routine branching instruction requesting signal when the number of times of generation of the control signal to the stack pointer 101 is counted by the prescribed number of times. Namely, when a microcomputer is normally operated, the sub-routine branching instruction is sporadically executed and since a CAL signal 102, which is generated at the time of executing the sub-routine branching instruction, is counted, the counter 106 of a plural bits construction executes an over-flow in a run-away condition to get into the infinite loop in which the sub-routine branching instruction is executed without limitation. Then, an INT signal 107, which is the carrying signal of the final step, is generated and the interruption processing is executed. Thus, the escape from the infinite loop can be attained.

Abstract: PURPOSE:To enable obtaining of an extraction-molded product whose straightness and uniformity in bending rigidity are high, by a method wherein a tow of a reinforced fiber to at least a unidirectional reinforced layer of which a twist has been given is used and a kind of fibers is made of carbon. CONSTITUTION:A tape 2 of bias cloth forming an inner layer is shaped cylindrically on a mandrel 3 and a carbon fiber tow 1 forming a unidirectional layer is obtained by giving a twist of 20T/m to a tow of 6,000fil.

Title: Chrominance signal interpolating system
Inventor: NINOMIYA YUUICHI
IPC: H04N11/02
Filed: 1983-10-11
Abstract: PURPOSE:To reproduce a chrominance signal with interpolation without widening a transmission band in comparison with a luminance signal by forming an interpolating signal of the chrominance signal based on the relative correlativity in horizontal and vertical directions to the luminance signal in a color picture signal. CONSTITUTION:The luminance signal fed to an input terminal 1 is fed to a vertical correlation detector 5 directly or through 1H delay lines 3, 4 and the vertical correlation value is detected. Moreover, the luminance signal is fed to a horizontal correlation detection 9 together with an output of 1-bit delay circuits 6, 7 and the horizontal correlation value is detected. On the other hand, a chrominance signal fed to an input terminal 2 is fed to interpolation filters 15, 18 via one-bit delay circuits 16, 17 to form vertical and horizontal interpolation chrominance signals, which are subject to gain control by the horizontal and vertical relative correlation signal which are calculated from the luminance signal at multiplyers 21, 19, then synthesized at an adder 22. Thus, an interpolation chrominance signal to be inserted and compensated to the reproduced chrominance signal is obtained from a terminal 23.

Title: Data transfer device
Inventor: SHIBATA YOSHIHISA
IPC: G06F13/12
Filed: 1987-07-29
Abstract: PURPOSE:To shorten waiting time for a transfer request given from another channel by comparing the channel command word CCW received from a channel that delivered a transfer request with the prescribed value and prefetching a next CCW in case a first CCW is smaller than the prescribed value and also the next CCW exists. CONSTITUTION:When a transfer request is received from a channel 11a, an interruption control part 3 sends a transfer command to a memory 1 via a prefetch control part 4. Thus the memory 1 sends the requested CCW to the channel 11a via a transfer control part 5 and also to the part 4 and a comparator 10. Here the comparator 10 detects the length of the CCW to compare it with the prescribed value and sends the result of this comparison to the part 4. In case the CCW length is smaller than the prescribed value and the chain information on the CCW received from a selector 8 shows the presence of the next CCW, the part 4 prefetches the next CCW. Thus a control part 2 can reduce the waiting time for the transfer request sent from another channel.

Inventor: YAO YOSHIHIKO
IPC: H01R4/18
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To easily form a tube part for insertion of a wire end, at the end of a short-sized wire obtained when a conductive metallic wire such as a copper round wire having the desired terminal diameter for connection of a wire is cut into a short size such that one terminal for connection of a wire can be formed. SOLUTION: A conical head 4a is formed at the end of a die pin 4 which forms a tube part (b) at the end of a short-sized wire (a). This allows the material of the short-sized wire (a) to be readily plasticized and flow along the conical surface of the conical head 4a to enable the tube part (b) to be easily formed. The die pin 4 is formed to have a diameter smaller than the maximum diameter of the conical head 4a. Thus, a clearance (s) is formed between the inner peripheral surface of the tube part (b) formed by the conical head 4a and the outer peripheral surface of the die pin 4, and a terminal A for connection of wire is pulled out of the die pin 4 after formation of the tube part, so that it can be easily pulled out at reduced resistance.
