Title: Manufacture of gas rate sensor, and gas rate sensor
Inventor: SHIRAKI IKUO
IPC: G01C19/00
Filed: 1993-12-16
Abstract: PURPOSE:To facilitate the construction of a gas rate sensor very much and to enable attainment of microminiaturization and high precision by forming electrodes and sensing wires on a base by etching and by forming through holes in the base by etching. CONSTITUTION:A pair of sensing wires 7a and 7b being separated from each other and so constructed as to be connected integrally to a plurality of electrodes 6a to 6d are formed independently by an etching treatment. Besides, frame parts 34 constituted of metal films 32 are formed in the vicinity of the electrodes 6a to 6d. Next, through holes 35 and 36 are formed correspondently to the wires 7a and 7b respectively by the etching treatment of a base 30 and an insulating film 31. The wires 7a and 7b are formed in a state of being independent of each other electrically by the etching treatment. A gas rate sensor 40 thus constructed is fitted to a casing and a gas is supplied from above the wires 7a and 7b. By putting this gas in a state of being passed through the through holes 35 and 36, a gas drift caused by an angular velocity input from outside can be detected as a difference between resistance values of the wires 7a and 7b.

Inventor: ITO HIROSHI
IPC: G01R31/08
Filed: 1990-11-20
Abstract: PURPOSE:To calculate overall length of an underground cable and compute the distance to the failed point by forming a bridge circuit from the cable to be measured, a slide resistor and a reference resistance, and determining the total resistance of the cable from the dividing proportion of this slide resistor under the bridge circuit equilibrium conditions and the value of the reference resistance. CONSTITUTION:One end of an underground cable 1b having a failure point is shortcircuited to one end of another underground cable 1a which is whole, and a slide resistor 7 is connected to the other ends so as to constitute a bridge circuit consisting of the failed cable 1b and the slide resistor 7. The ratio of distance till the failed point to the sum of cables 1b, 1a is calculated from the dividing proportion of the resistor 7 under the equilibruim conditions. A reference resistance 10 is interposed between the resistor 7 and cable 1b to constitute a bridge circuit, and the sum of the cables 1b and 1a is calculated from the conductor specific resistance of the cables 1b, the reference resistance value, and the dividing proportion when bridge circuit is formed by interposing the reference resistance 10, and from this sum the distance to the failed point can be calculated.

Filed: 1992-11-27
Abstract: PURPOSE:To transfer an anisotropically conductive adhesive which has high uniformity of film thickness to a predetermined position by thermocompression bonding. CONSTITUTION:A carrier tape 3 moves intermittently in arrow-X direction. An extremely narrow base tape 4 to whose lower surface an anisotropically conductive adhesive 5 is continuously applied moves intermittently in arrow-Y direction. Then, in the crossing part of those tapes 3 and 4, the anisotropically conductive adhesive 5 applied to on the lower surface of the tape 4 is transferred to the upper surface of the carrier tape 3. At this time, a front end 5a and a rear end 5b of the anisotropically conductive adhesive 5 are separated from the anisotropically conductive adhesive 5 easily by stripper film 6 provided on the lower surface. Accordingly, even if the base tape 4 to whose lower surface the anisotropically conductive adhesive 5 is continuously applied is used, transfer of the anisotropically conductive adhesive 5 to the base tape 4 can be attained by solid coating using a roll coater without any problem.
