Title: Partial discharge detection method
Inventor: UCHIDA YOKO
IPC: G01R31/12
Filed: 1993-06-28
Abstract: PURPOSE:To allow accurate and quick noise-free detection of partial discharge by comparing the frequency characteristics of a detected waveform with those of a simulated partial discharge waveform being stored in a neural network and a noise waveform. CONSTITUTION:A simulated partial discharge signal, injected 12 into an embedded electrode 4b, is introduced through a voltage divider comprising stray capacities C1, C2 into a gas insulated machine. It is transmitted at same rate as an actual partial discharge signal and then superposed on the bearing voltage of a capacitor 5 through a voltage divider comprising one embedded electrode 4a before it is detected as a partial discharge waveform. Features of its frequency characteristics are then extracted and standardized to produce a frequency distribution pattern which is stored in a neural network. The frequency distribution pattern of noise waveform is also stored in similar manner. Upon actual occurrence of partial discharge or noise in a gas insulated machine, the frequency characteristics thereof are compared with stored frequency characteristics of simulated partial discharge and noise and a decision is made whether the detected waveform is a partial discharge waveform or a noise waveform.

IPC: H04N1/405
Filed: 1984-07-27
Abstract: PURPOSE:To attain picture processing without missing of dots by delaying converted binary-decoding data in a specific direction and applying logical operation between the delayed binary-coded data and non-delay picture element data. CONSTITUTION:An original density signal obtained by an image sensor 1 is inputted to a differentiation circuit 2, where the signal is differentiated. A weight coefficient to a line drawing threshold value and a gradation processing threshold value is given by a weighting circuit to the differentiated value. Then a threshold circuit 4 receives an output of the circuit 3, multiplies each weight coefficient to each threshold value to calculate a new threshold value. A comparator circuit 6 compares an original picture density signal with the new threshold value and applies binary-coding. After the binary-coded data is retarded by one picture element by a succeeding delay/operation circuit 7 in at least one direction out of the main scanning and the sub-scanning directions, the circuit 7 ORs the data and the non-delay picture element data and gives an output of picture data.

Title: Oil-base ball point pen ink
Inventor: TANI HIDEAKI
IPC: C09D11/17
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To obtain an oil-base ball point pen ink minimized in a problem of dripping a blob of ink when used for writing by mixing an organic solvent with a colorant, a resin and a neopentylpolyol fatty acid ester. SOLUTION: An organic solvent is mixed with a colorant, a resin and a neopentylpolyol fatty acid ester. It is desirable that the amount of the ester added be 1-10% and that the number of carbon atoms of the fatty acid be 4-17. The ester has good compatibility with and a good affinity for the organic solvent, the dye, the pigment and the oil-soluble polymer used in the ink. It has therefore an effect of lubricating the metal being the material of which the tip or ball of a ball point pen is made, causes the ink to show lowered surface tension and improved wetting properties, to stick weakly around the rotating ball and to form a thinned ink layer on the ball. As a result, it can give oil-based ball point pen ink markedly reduced in the tendency to drip a blob of ink.

IPC: C01B3/38
Filed: 1977-12-28
Abstract: PURPOSE: The title device designed to maintain the air/fuel ratio at a constant value always by changing the fuel feeding pressure according to the change in air feeding pressure simultaneously, wherein a specific fuel pressurizing unit is provided between a fuel feed unit and a fuel adjusting throttle.  
     CONSTITUTION: Air is fed from the nozzle 23 of the air feed unit 2 to the reactor 1 at flow rates of a 1  and a 2  with the engine 8 rotated. The interior of the float chamber 71 is pressurized by the air injection pressure Psa via the fuel pressurizing port 74. Fuel is fed from the outlet 34 of the fuel feed unit 3 to the feed port 73 under a pressure of Psf to control the fuel level of the chamber 71 with the float valve 72. The feeding pressure of air to the reactor 1 equal to the fuel feeding pressure makes the air injection pressure Psa apply to the fuel pressurizing unit 7 even when the pressure Psa changes with the change in the number of revolutions of engine 8, thus maintaining the air/fuel ratio constant with a change in feeding pressure Psf 1  of the fuel fed from the outlet port 75.
