IPC: G01R31/02
Filed: 1993-01-12
Abstract: PURPOSE:To realize simple and positive maintenance/inspection work for distribution line by providing a convenient method for deciding the cause of ground fault of high voltage distribution line. CONSTITUTION:A large number of Vo and Io waveforms are sampled (Step S1) for various causes of fault using a simulated high voltage distribution line and each sample waveform is subjected to FFT analysis upto a predetermined order (Step S2). Higher harmonic containing rates obtained through PFT analysis are then averaged for each order and each group having similar fault cause and the distribution pattern of higher harmonic containing rate and the total of the average values is determined (Step S3). Maximum and minimum total values are then shown on graphs for various causes of fault (Step S4) and the cause of ground fault is determined for a decision object, i.e., an actual distribution line, using the graphs.

Title: Structure of spray nozzle
Inventor: MAESHIBA SOUZABUROU
IPC: F16K31/58
Filed: 1982-01-11
Abstract: PURPOSE:To enable to prevent the water from being sprayed wastely from the spray nozzle by a structure wherein an operating rod, which is protrusively provided at the front of a valve flange, is expanded into an elastic hose connected at the tip of a nozzle main body. CONSTITUTION:An opening 6 at the end of the nozzle main body 3 is closed with the valve flange 7 by means of water pressure applied thereupon, when the water is supplied from a water supply hose 1. When the elastic hose 5 is pushed down, simultaneously the operating rod 8 is also pushed down, resulting in tilting the valve flange 7 with the tilting of the rod 8 in such a manner as to make a gap, through which the water is flowed to be able to spray between the opening 6 at the end of the nozzle main body 3 and the flange 7. When the elastic hose 5 is restored to the original un-pushed down state, the opening 6 is brought back to its original closed state. In such a manner as mentioned above, the water from the spray nozzle is prevented from being sprayed wastely.

Abstract: PURPOSE:To improve the temperature controllability of a hot stove in a method for controlling the exhaust gas temperature of the stove, by controlling the set value of a flow rate controller so that the exhaust gas temperature becomes the secondary upper limit at the time of completion of burning. CONSTITUTION:An M gas is supplied to a hot stove 3 from a pipeline 1 and its flow rate is inputted to a flow rate controller 6 as a flow rate signal Q from a flow meter 5.

Title: Auto-focusing device
Inventor: AKASHI AKIRA
IPC: G02B7/36
Filed: 1987-01-12
Abstract: PURPOSE:To improve the reliability of a focusing instruction by inhibiting the focusing instruction after driving a lens if the driving based upon a defocused value is not normally executed at the time of executing the focusing instruction immediately after driving the lens when the defocused value is <= a prescribed value and then executing focus detecting operation again. CONSTITUTION:When a calculated defocused value based upon the focus detecting operation is <= the prescribed value, a microcomputer PRS outputs a focusing instruction immediately after driving the lens without executing the focus detecting operation again, and when the lens is not moved by a distance corresponding to the defocused value at the time of lens driving, executes the focus detecting operation again after the lens driving independently of the size of the calculated defocused value. Only when focusing is decided as the result of the detecting operation executed again after the lens driving, the focusing instruction is outputted. Even if the lens is abutted upon a mechanical limit position such as an infinite position or a close range position and the lens can not be driven furthermore, a trouble outputting the focusing instruction immediately after the lens driving can be obviated.
