Title: Propagation delay testing method for logic circuit
Inventor: IKEDA KOJI
IPC: G01R31/28
Filed: 1987-08-11
Abstract: PURPOSE:To easily test a propagation delay by setting an optional flip-flop in an optional state directly from the outside. CONSTITUTION:An input variation signal is propagated on a path 117 to be tested and appears at a D entrance pin of the flip-flop 104. The variation at the D entrance is inputted to the flip-flop 104 unless there is no trouble of propagation delay on the path 117 to be tested. If, however, there is delay trouble, the flip-flop does not change its state. Here, the state of the flip-flop 104 is scanned out so as to decide the trouble of propagation delay on the path 117. Namely, the flip-flop 104 is selected with a scan-address pin 112 to obtain the state of the flip-flop 104 on the scan-out pin 116. This value shows there is no propagation delay on the tested path 117 when it is a signal value after the variation at the output terminal of the object path 117, but indicates the trouble of propagation delay on the object path 117, and consequently the propagation delay can be tested.

Patent JP-S6091787-A (JP)
Title: Gate signal generator
Inventor: MATSUSHITA AKIRA
IPC: H04N7/035
Filed: 1983-10-26
Abstract: PURPOSE:To generate a gate signal almost immune to the effect of jitter in a horizontal synchronizing signal even if a color burst signal is included in a video signal by deciding whether or not the color burst signal is included in the video signal from the changing state of a latch data latched in synchronizing with the horizontal synchronizing signal. CONSTITUTION:A horizontal counter 25 is brought into self-reset state, a count output at that time is latched by a latch circuit 9 in synchronizing with the horizontal synchronizing signal and whether or not the color burst signal is included in the video signal is decided from the changing state of the latch data. When included, the counter 25 is brought once into the external reset state, the pull-in operation synchronized with the horizontal synchronizing signal is executed and when it is finished, the state is switched to the self-reset state. On the other hand, when not included, the counter 25 is held to the external reset state. Since the counter 25 is driven with the self-reset after it is synchronized once with the horizontal synchronizing signal (HD) when the color burst signal exists, even if jitter is caused in the horizontal synchronizing signal HD, the phase of a gate signal G1 is almost unchanged.

Title: Processor equipped with writing-in mechanism for instruction caches
Inventor: NISHIYAMA HIROYASU
IPC: G06F12/08
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To suppress low the decrease in performance due to main storage reference at dynamic instructing generating by providing in an instruction set an instruction, capable of specifying by each memory area as an area which is written through a data cache or an area which is written through an instruction cache. SOLUTION: In the instruction set, the instruction is provided which can specify each memory area as an area which is written via the data case or an area which is written through the instruction cache. This processor writes an instruction generated dynamically by ALU 105 directly to the instruction cache 102 through a memory unit 107, after it is stored in a register 106. The generated instruction, when executed is read out of the instruction cache 102 by a memory unit 107 and passed to an instruction decoder 108. Thus, the instruction written to the instruction cache 102 can be executed directly not through a main storage 104, so that the execution of the dynamically generated instruction can be speeded up.

Title: Shunt contained in semiconductor module
Inventor: TANAKA SEIJI
IPC: H01L25/07
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To heighten a thermal conduction effect, suppress the temperature rise and allow a fine adjustment in a manufacturing process by forming so as to be wire bonded and delivered to a current detector at desired two positions on the top surface of a metal piece. SOLUTION: On the top surface of a metal piece 1 a bonding wire 6 for delivering a voltage to a current detector from desired two positions P, Q is positioned and bonded, with measuring the resistance value between two points on its mounting parts P, Q. The shunt having such an arrangement is soldered to the same Cu circuit 4, together with a semiconductor chip or circuit elements constituting the current detector. Heat generated by the resistance of the shunt is transferred to a metal board 2, and it is cooled by the radiating action of the metal board 2. Thus heat generated in the shunt is radiated from the wide- area surface of the closely contacted metal board 2, thereby suppressing the temperature rise, an accuracy lowering factor, and the fine adjustment can be made since the bonding is made with measuring the resistance value.

Title: Maximum likelihood decoder
Inventor: ETOU YOSHIZUMI
IPC: H03M5/16
Filed: 1982-11-17
Abstract: PURPOSE:To simplify the circuit and to attain high speed operation of the circuit by using a difference between likelihoods of two state at a state estimating section of the maximum likelihood decoder. CONSTITUTION:A receiving value yn at an input terminal 12 is converted into a binary code at an A/D converter 13 and quantized into 4-bit. In taking a likelihood m0(n) where a ternary signal goes to +1 at a time (n) and goes to (0) or -1 at a time (n+1), and a likelihood mE(n) where the signal goes to -1 at a time (n) and (0) or +1 at (n+1), the difference of the likelihoods DELTAm(n)=m0(n)- me(n) has only a half the amplitude of the yn and becomes 3-bit, and total 7-bit of the yn and the DELTAm(n) is applied to an address input to an ROM 14. The ROM 14 outputs the difference of likelihoods DELTAm(n+1) in 3-bit after one data period, a change d0(n+1) in 1-bit and a dE(n+1) in total 5-bit. The DELTAm(n+1) is stored temporarily at each period of data to a latch 15 of 3-bit and used as the address input of the ROM at the next time. The d0(n+1) and dE(n+1) are outputted from terminals 16, 17 and used as the input to a decoding value estimating section.
