摘要： PROBLEM TO BE SOLVED: To provide a fluororubber-base adhesive excellent in resistances to heat and moisture by compounding four specific ingredients. SOLUTION: A fluororubber-base adhesive in the form of a soln. in a low- boiling ketone solvent is prepd. by compounding 100 pts.wt. fluororubber (A) comprising a vinylidene fluoride-hexafluoropropene copolymer having 0.1-30% unsatd. bonds introduced into the molecule by the defluorination caused by the treatment with an alkaline substance (e.g. sodium hydroxide or potassium hydroxide) at 40-60 deg.C in a ketone solvent (e.g. acetone or methyl ethyl ketone) with 0-30 pts.wt. glycidyltype epoxy resin (B)(e.g. an epichlorohydrin-bisphenol A resin, an arom. glycidyl ether resin, or an aom. glycidylamine resin), 1-30 pts.wt. diamine compd. curative (C)(e.g. diaminodiphenyl sulfone or diaminodiphenylmethane), and 1-20 pts.wt. alicyclic bismaleimide compd. (D)(e.g. one represented by the formula). The adhesive is used e.g. for bonding a cover film of a flexible printed circuit board.

摘要： PURPOSE:To prevent the occurrence of malfunction, erroneous input, switch damage or dew condensation, and improve reliability by keeping the required gap on the upper part of the operation panel of n diaphragm type keyboard switch and providing a transparent flexible insulation sheet therein. CONSTITUTION:Transparent flexible insulation sheets 1 and 5 are arranged on the upper part of a diaphragm type keyboard switch via a transparent spacer means 3 in order to keep the required gap. Also, the transparent flexible insulation sheet faced to the gap is fitted with a transparent conductive film 7 for heat generation. The gap, therefore, works as an insulation region and forms a cushion layer against heat applied from the upper surface of the keyboard switch. According to the aforesaid construction, the heat resistance of the keyboard switch proper is enhanced. Also, in an operation environment at a low temperature, dew condensation and the like are pertinently prevented via the effect of heat generation by the conductive film 7 and high reliability can be ensured.

摘要： PURPOSE:To make it possible to detect even the level change of various fluid accompanying friction resistance, by constituting the titled sensor so that the change in the pressure of a fluid is applied to one of vibration nodes of a piezoelectric vibrator as concn. load through a flexible member and a pressure transmitting member. CONSTITUTION:The outside vibration node B of a piezoelectric vibrator 2 is fixed to the step part 4 of a case 1 by an adhesive to be supported thereby and, next, a flexible member 5 is mounted to the upper surface of said vibrator 2 through a pressure transmitting member 9 and a plate body 8 and an outer peripheral mount part 6 is connected to the upper end of the case 1. The pressure of the fluid is received through the flexible member 5 forming a required gap 7 between said flexible member 5 and the vibrator 2 without contacting the fluid to be subjected to level detection such as a particulate or a fluid with the piezoelectric vibrator 2 and the pressure of the fluid is applied to the inside vibration node A of the piezoelectric vibrator 2 as conc. load by the plate body 8 and the pressure transmitting member 9. By this constitution, stable and certain fluid level detecting operation can be achieved.

摘要： PURPOSE:To obtain a lithium niobate substrate capable of enhancing yield at the time of producing an optical device and capable of reducing DC drift after the production of the device by heat-treating a lithium niobate wafer under specified conditions. CONSTITUTION:A lithium niobate (LiNbO3) wafer is heat-treated at 1,040+ or -30 deg.C for 5-20hr and the allowable time precision is regulated to + or -0.4hr. The reproducibility of lithium vacancy grating density is improved, the reproducibility of resistivity can also be improved and the objective LiNbO3 substrate ensuring a stabilized number of charged bodies transferred by an electric field and stabilized valency is obtd.

摘要： PURPOSE:To prevent the possibility of erroneous input due to the touch of a hand by forming an insulating projection protrusively between electrodes in the parallel line shape electrode group of an electrode plate on one side. CONSTITUTION:On the plane on one side of flexible insulating sheets 1 and 6, a pair of electrode plates having the parallel line shape electrode groups 2 and 7 and a resistor connected to each end part of the parallel line shape electrode groups 2 and 7 are provided, and at least either the electrode plates is constituted so as to provide the insulating projection 4 formed protrusively between the electrodes of the parallel line shape electrode groups 2 and 7. And a device is constituted in such a way that both electrode plates are arranged so as to confront the parallel line shape electrode groups 2 and 7 of both electrode plates with each other in a direction to intersect orthogonally by interposing or without interposing a pressure sensitive type anisotropic conductive rubber sheet 5. In such a way, it is possible to solve the problem of the erroneous input due to the touch of the hand and to obtain superior reliability as securing high resolution.
