Inventor: FUJII MASAMI
IPC: H01R4/66
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To bury a plurality of earth electrodes at different earth depth in a single dug hole. SOLUTION: A plurality of earth electrodes 1, 2, 3 kept as insulated electric wires to different depth points from the surface of the ground and made naked electric wires at the lower part are buried in a dug hole H. In this case, at the time of boring the dug hole H, the drilling pipe itself is used as an earth electrode and the earthing resistance is measured for every depth point as the depth is deepened and then the earthing resistance RE1 of an earth electrode 1 is computed from a calculation expression: RE1 =(RT1 ×RL1 )/(RT1 -RL1 ), wherein RT1 is the measured earthing resistance value RT1 corresponding to the depth T1 at the lower end of the insulated electric wire part of the earth electrode 1 and RL1 is the measured earthing resistance value RL1 corresponding to the depth L1 at the lower end of the necked electric wire part of the earth electrode 1.

Title: Resistance sensitive type tablet
Inventor: YOSHIKAWA OSAMU
IPC: G06F3/03
Filed: 1990-11-19
Abstract: PURPOSE:To improve the accuracy of an A/D converting circuit by connecting section electrodes which are parallel to both-end electrodes of a resistance plate to the A/D converting circuit through changeover switches which are switched at every section corresponding to detected position data. CONSTITUTION:An X-axial resistance plate 2 where X-axial electrodes 1a and 1b are formed and a Y-axial resistance plate where a Y-axial electrode is formed are superposed with a minute insulation gap. 1st and 2nd changeover switches 33 and 34 are switched to contacts (a) and (a) on the sides of a 1st section 2a and a pen 7 is considered to be pressed against a point P in a 2nd section 2b. The voltage of a positive auxiliary electrode 20a and the voltage of a section electrode 31 are sent as a reference voltage to the A/D converting circuit 10. Those are larger than the P-point voltage and not within the range, so they become overflow outputs and a CPU 32 outputs a switching signal to changeover the switches to contacts b, b on the sides of a 2nd section 2b. The P-point output is within the voltage range between the electrode 31 and a negative auxiliary electrode 20b and the position data is outputted. Position data is also outputted similarly by the Y-axial resistance plate.

Filed: 1989-12-05
Abstract: PURPOSE:To make it possible to rewrite characters on a space concealed using a correction device, in a short time by sintering a compound of a component which forms ceramic of silica, alumina or magnesium, and vinyl acetate resin, titanium oxide and boron nitride. CONSTITUTION:A component which forms ceramic of silica, alumina or magne sium, vinyl acetate resin, titanium oxide and boron nitride are heated at temperatures of 700 deg.C to 1,000 deg.C in air. Subsequently, the ceramic component remaining after the resin component is oxidized, carbonated, gasified and spread out as carbon oxide, becomes sintered and thus a solid correction device is obtained. The preferable dosage of the ceramic component is 10 to 40 weight% for the total composition. If the dosage is more than 40 weight%, the writing properties become deteriorated. If the dosage is less than 10 weight%, the device becomes brittle. The preferable dosage of vinyl acetate is 10 to 30 weight%. If the dosage is more than 30 weight%, the device becomes brittle, and if the dosage is less than 10 weight%, it is difficult to mold it. Boron nitride prevents the sintered solid correction device from becoming too rigid. The preferable dosage of boron nitride is 5 to 20 weight% of the total composition.
