Patent JP-2001242118-A (JP)
Title: Gas sensor
Inventor: AKATSUKA SHOJI
IPC: G01N27/409
Filed: 2000-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a gas sensor for introducing atmosphere from the outside for its functioning and capable of keeping the insulating capacity across the electrode terminals arranged therein. SOLUTION: An oxygen sensor is constituted, so that the opening part formed to the upper end thereof is closed in an air permeable state by a sealing unit 14, constituted by holding a sheet-like water repellent filter 50 between a sealing member 15 and a pressing member 16. The open air, introduced via the water repellent filter 50, is once guided outwardly in the sealing unit 14 by a plurality of venting paths 15a, to be introduced into an outer cylinder. Therefore, even if steam flows in, along with the open air to become waterdrops through dew condensation, waterdrops will not fall directly on the terminals of electrodes to which lead wires are connected, and they will adhere to a vent groove 17b or to the vicinity of the outer periphery of a separator 18 to evaporate, before long.  Accordingly, the problem of shortcircuiting the terminals will not be generated, and the accuracy of the oxygen sensor 1 can be kept satisfactorily.

IPC: E02D5/80
Filed: 2000-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a water stop construction in an anchor construction in which the water stop function is not deteriorated event when a tension member is tensed. SOLUTION: A tension member (PC stranded wire 1) to be inserted into an anchor installed hole, an anchoring device for fixing the tension member to one end side of the anchor installation hole and grout 2 to be filled between the anchor installation hole and tension member are provided. At one end side of the tension member, the grout 2 and the tension member are isolated and a free length portion is formed, at the other end side, the tension member is anchored with the grout 2 and an anchored length portion is formed. The boundary between the free length portion and the anchored length portion is sequentially covered with an adhesive 4 and a thermal shrinkage tube 5. An insulation layer 6 for isolating the thermal shrinkage tube 5 and the grout 2 are provided.  When the tension member is tensed, the direct adhesion force between the thermal shrinkage tube 5 and the grout 2 is lost and thus adhesion force at the interface between the tension member and the adhesive 4 or the interface between the thermal shrinkage tube 5 and the adhesive 4 does not show a considerable change and thus the water stopping property can be maintained.

Abstract: PROBLEM TO BE SOLVED: To provide a stable motive power transmission mechanism having no influence by a change in an ambient temperature, capable of preventing an entrance of foreign matter, capable of preventing abrasion, capable of preventing rust and capable of surely maintaining a cutoff state after cutting off the transmission of torque once. SOLUTION: When generating torque exceeding a preset value by an accident of a compressor 1, one taper surface (either one according to the rotational direction of a pulley) of respective radial directional tapered recessed parts 8a of a pulley 4 side inner ring 8 presses respective balls 9 to be moved to respective radial directional and rotary shaft directional recessed parts 10b of a hub 10. Since there is the slight possibility of returning the respective balls to the radial directional outside in a state after this movement, the respective one taper surfaces and an inclined face 12a of a ball pressing ring 12 move the respective balls further to the respective rotary shaft directional inmost recessed parts 10c, so that the respective balls are surely checked from returning to the radial directional outside.  Thus, since the inner ring and the respective balls separate from each other, rotation of the pulley is not transmitted to a rotary shaft 2 of the compressor.
