Title: Logical simulation system
Inventor: YAMAMOTO WATARU
IPC: G06F17/50
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To accelerate simulation processing by dealing with an event outputted by a circuit element being a zero delay and a combinatorial logic in real time. SOLUTION: This system consists of a circuit element evaluation device 11, a time wheel 12, a present time event memory 131, an event after the present time memory 132, circuit to be verified data 14 and circuit element identification data 15. The system holds circuit element identification data 15 being information for discriminating whether the circuit element is a zero combinatorial logic or not concerning each circuit element of the circuit to be verified. Based on this data, the registering time of an event outputted from one circuit element by the input event at time T is set to be a presentime T in the case of a zero delay combinatorial logic, and in the other cases the event of zero delay is set to be time (T+Δ) and an event with delay (d) larger than zero is set to be time (T+d). Consequently, additional information to the time wheel 12 is eliminated.

Title: Scroll compressor
Inventor: HIRANO HIDEO
IPC: F04C29/04
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To provide high gas injection performance with a low injection pressure in a heating operation requiring a high-load operation by providing offset surfaces of blades for forming a pair of compression chambers between a fixed scroll and a speed-variable rotating scroll. SOLUTION: In a compression chamber 13B, the sealing property of a sucked coolant is improved to increase the inlet quantity of the coolant because a clearance S is small, and a rotating scroll 12 is rotated at a high speed. In the compression stroke, a supercharge according to the high-speed operation degree to low-speed operation is performed. Further, a low-pressure gas injection is performed by utilizing the whole body of the compression chamber 13B having a large capacity including the area having the clearance S. Thus, the injection flow rate is shifted to large flow rate side over a standard flow rate to ensure a high injection flow rate, so that the actual coolant discharge quantity can be sufficiently increased. Thus, the performance in a high-load operation such as heating is also improved.

Filed: 1991-10-16
Abstract: PURPOSE:To efficiently execute plasma treatment to a flowing material at the inner face or at the inside of an insulated tube whose outer peripheral part is provided with a pair of spiral parallel electrodes by introducing a reactive gas from one end part of the tube and generating low pressure glow discharge plasma at the inside of the tube.

Title: Poor vacuum sensing device for vacuum breaker
Inventor: WATANABE KENJI
IPC: H01H33/668
Filed: 1988-10-24
Abstract: PURPOSE:To prevent malfunction despite eventual generation of creeping corona discharge by calculating the standard deviation value which represents phase dispersion in the discharge pulses superposed over the discharge signal, and judging as poor vacuum condition if the calculated standard deviation is smaller than the set value and the frequency in generation of pulse signals is greater than a set value. CONSTITUTION:When discharging is generated in a vacuum breaker 1, a grounding electrode 17 senses a discharge signal consisting of power supply frequency waveform which is superposed with the amount corresponding to the discharge pulses. A window signal generator 26 emits a window signal while a pulse signal generator 37 gives out pulse signals. A calculating device 35 adds together the time difference between pulse signal and window signal for a certain period of time according to the frequence of occurrence to thereupon determine the mean value of time differences, and thus the standard deviation is determined. A poor vacuum condition judging device 36 judges that the vacuum breaker 1 has generated discharging originating from poor vacuum condition when the frequence in generation of pulse signals is greater than the set value. This permits distinction of discharging deriving from poor vacuum condition from creeping corona discharge, and no malfunction will be generated despite eventual occurrence of creeping corona discharging.

IPC: C23C18/12
Filed: 1989-10-14
Abstract: PURPOSE:To obtain a thin chromium film which is thin in film thickness and small in dispersion by a simple method by incorporating chromium resinate, metallic resinate such as Rh, Bi and Sb as the other metallic component, resin and an organic solvent. CONSTITUTION:A solution is utilized which incorporates chromium resinate, metallic resinate of at least one kind selected from among Rh, Bi, Sb, Pb, B, Si, Al, Ca, Mg, Mn, Zn, Zr, Ba, Sr and Co, resin as a binder and an organic solvent. A dense, uniform and thin film is obtained in a simple method by applying this chromium metallo-organic to a base material, drying and calcining it. The other metallic component except chromium stabilizes a thin chromium film and enhances adhesive property of the thin film for the base material such as ceramics. Oxidation of Cr is prevented by controlling the loadings thereof. The resin regulates viscosity to a proper degree and prevents evaporation of the metallic resinate of the other metallic component. The solvent makes the solution uniform and enhances appliableness and printability and also uniforms the forming composition and thickness of the thin film.
