Title: Chrominance signal separating circuit
Inventor: SHIBAYAMA TAKECHIKA
IPC: H04N9/78
Filed: 1987-01-26
Abstract: PURPOSE:To eliminate color blurring in a vertical direction by constituting the titled circuit with a BPF having a specified passing band for a carrier chrominance signal and color classification carrier, a filter having a specified filter characteristic for a video signal, and an adder. CONSTITUTION:The center frequency of the BPF 6 is the color subcarrier frequency fsc of the carrier chrominance signal in a video signal, and its passing band is fsc+ or -100KHz. A delaying circuit 7 matches the output of the BPF 6 and an input signal in terms of time. Accordingly, from a subtractor 8, a video signal to which a band erasing filter characteristic whose attenuation band is the passing band of the BPF 6 is applied is taken out, and is supplied respectively to a one-H delay circuit 9 and a subtractor 10. The subtractor 10 is a circuit to subtract the input and output video signals of the circuit 9, and forms a comb-line filter for chrominance signal jointly with the circuit 9. The output of this filter circuit is added with an output signal from the BPF 6 in the adder 11. Therefore, an input color video signal is given a flat pass- characteristic in the pass band of the BPF 6, and in bands other than the above- mentioned, the characteristic of the above-said filter circuit is given. As a result, a carrier color signal is separated and outputted to an output terminal.

Title: Traffic control system for packet exchange network
Inventor: YOSHIKAWA YASUSHI
IPC: H04L12/721
Filed: 1990-01-24
Abstract: PURPOSE:To utilize other resource of a network effectively and to improve the service before the restriction is implemented depending on the congestion of a specific node by informing a passing coefficient to each node from a network management center and allowing each node to select an optimum path based on the passing coefficient. CONSTITUTION:A network management center 110 gives a command to a passing coefficient revision means 12 via a traffic control means 11 by a command of the operator. The means 12 informs the passing coefficient to be revised to a passing coefficient storage means 41 of an object exchange node 40. A passing degree calculation means 45 calculates the degree of passing for each relay line based on the operation of an adjacent node from a dialing state operation degree storage means 44 and information from the means 41. A path selection means 46 compares the passing degree of each relay line to select the relay line whose degree of passing is maximum among usable relay lines. Thus, before the restriction is implemented due to the congestion state of a specific node, the other resource of the network is utilized effectively and the service is improved.

Title: Liquid crystal injection device and liquid crystal injection method by this device
Inventor: SANO KAZUYOSHI
IPC: G02F1/1341
Filed: 1992-01-30
Abstract: PURPOSE:To inject liquid crystals into liquid crystal cells in a short period of time and to improve the productivity of the liquid crystal display device by rotating a rotating plate in the state of imposing the liquid crystal cells on a liquid crystal tray. CONSTITUTION:The liquid crystal cells 7 are first imposed on the liquid crystal tray 5 in the state of directing liquid crystal injection ports inward in the radial direction of the rotating plate 6. The pressure in a vacuum vessel 2 is then reduced to evacuate the liquid crystal cells 7 to a vacuum. The rotating plate 6 is rotated in a prescribed direction at a prescribed rotating speed when the evacuation to the vacuum is sufficiently executed. The vacuum vessel 2 is then internally pressurized up to the atm. pressure. The liquid crystals 4 are concentrated toward the outer side of the liquid crystal tray 5 by centrifugal force, by which the liquid crystal injection ports 7a are immersed into the liquid crystals 4 and the liquid crystals 4 are injected by capillarity into the liquid crystals 7 via the liquid crystal injection ports 7a. Since the centrifugal force acts on the liquid crystals 4, the injection of the liquid crystals 4 is accelerated and the injection rate is accelerated. As a result, the need for moving the liquid crystal cells 7 to the liquid crystal tray 5 is eliminated, the need for the moving mechanism for this purpose is eliminated.

Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To continue air-fuel ratio control without deteriorating drivability and emission and without causing torque shock when the target air-fuel ratio is drastically changed or just after open loop control is shifted to feedback control. SOLUTION: A CPU 31 in an ECU 30 sets the target air-fuel ratio, corrects the set target air-fuel ratio according to the lean or rich degree, and feedback- controls the actual air-fuel ratio of exhaust gas discharged from an engine 1 to the target air-fuel ratio. When it is judged that the target air-fuel ratio is largely changed in shifting from theoretical air-fuel ratio feedback control to lean feedback control, the CPU 31 temporarily interrupts feedback control. When the deviation between the actual air-fuel ratio and the target air-fuel ratio is not more than a specified value, the feedback control is restarted.
