Title: Optimizing control method
Inventor: KOUNO MINORU
IPC: G05B13/04
Filed: 1983-12-12
Abstract: PURPOSE:To realize an excellent optimizing control by setting a limit time to the convergent calculation of a computer in response to the control period and repeating the converging calculation within the limit time so as to calculate the best evaluation function value thereby obtaining the excellent optimum solution. CONSTITUTION:When an initial value is set and the state where no optimizing solution is obtained is discriminated, the converging calculation is executed only once and the 1st optimizing solution is obtained. When the optimum solution exists, it is compared with the preceding calculation result, and when said solution is a better solution, it is preserved and the converging calculation is repeated until it is discriminated that the time reaches the limit time. The arrival of the limit time is discriminated by counting a unit calculation time (k) and discriminating that it reaches the limit count value k1. An object function value (f) (shown in dotted lines) is decreased as the calculation is repeated, a limit error (c) is decreased sequentially and it reaches a limit permissible error epsilon1 or below at k=5. In selecting k1=11 for example, the error (c) is decreased up to a value S2 and the better optimizing control is attained.

IPC: F02M37/00
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To prevent damage to or breakage of a fuel tank by providing a bypass fuel passage so as to limit the maximum pressure inside a fuel tank so that the fuel passes through the passage when the pressure inside the fuel tank exceeds a predetermined maximum pressure, and the fuel passes through a supply neck to an upstream to be discharged into the atmosphere. SOLUTION: A supply duct of a fuel tank has a supply neck 14. The supply neck is structured so that it accommodates a fuel supply nozzle of a fuel supply pump of a gas station. The supply neck comprises a bypass passage 18, and the fuel passes through the bypass passage 18 to be discharged from the supply duct when the pressure inside the fuel tank exceeds a predetermined maximum level. The fuel rises and passes through the bypass passage 18, then passes through a fuel supply nozzle receiving ring 66 of a fuel supply neck housing. Then, the fuel passes through a clearance 92 of a rib 84, and finally flows out from a slot 93 of an entrance 50 of a housing 62. This occurs when the tank is filled with excessive fuel. Thus, excess pressurization inside a fuel tank 12 which may lead to damage or brakage of the fuel tank is prevented.

IPC: G01N27/72
Filed: 1990-09-05
Abstract: PURPOSE:To enable stable measurement of a density of current flowing through a sample within a bias magnetic field by arranging an excitation coil and a detection coil so that the directions of axis lines thereof are both vertical to the surface of the sample in a reflection type probe. CONSTITUTION:A detection coil 3 is wound so as to wrap the tip of a core rod 2 positioned along an axis line of a probe 1 and a pair of excitation coils 4a and 4b (4) is wound outside the coil coaxially. The coils 4a and 4b are the same in shape and number of turns but arranged opposite in direction to each other. The probe 1 is arranged close to a sample layer 6 of a thin film as superconducting body. Then, the sample layer 6 is cooled down until it becomes superconductive. Then, the coil 4 is fed with a specified current. At this point, an induced current flows through the sample layer 6 so as to cut a magnetic field formed by the coil 4 and a magnetic field formed by the induced current is detected with the coil 3. When the induced current reaches a critical current, a pattern of the magnetic field detected with the coil 3 begins to divert from a common waveform at the moment thereby allowing the measuring of the critical current.

Title: Superconducting logic circuit
Inventor: ASAHINA KATSUSHI
IPC: H01L39/22
Filed: 1987-09-17
Abstract: PURPOSE:To obtain a superconducting logic circuit capable of performing switching operation with an input of a decreased logic amplitude and still having a large margin to noise when the circuit is not operating, by providing a quasiparticle injecting means for injecting quasiparticles into a superconductor in synchronization with a clock oscillator used in a synchronizing circuit. CONSTITUTION:A photon injecting source 12 is turned ON or OFF in synchronization with clock signals from a synchronizing circuit, so that the circuit operates to switch between points A and B when the source 12 is OFF and to switch between points B and C when the source 12 is ON. Accordingly, the logic amplitude of the circuit is decreased during operation and, therefore, the circuit can perform rapid switching operation. When the circuit is not operating, on the other hand, the logic amplitude is increased and, hence, the circuit has large margin to noise. Further, since a quasiparticle injecting means is provided by the photon injecting source, constant signal delay can be obtained in the circuit for injection of quasiparticles even if the degree of integrity of the circuit is increased.
