Abstract: A balloon includes two joined plastic films. The balloon includes: a gas supply valve sandwiched between and joined to the first film and the second film; a first chamber receiving air supplied from the gas supply valve for expansion; and a second chamber communicating to the first chamber. The gas supply valve includes a gas passage that extends from a gas inlet positioned on an outer side of the second chamber to an inside of the first chamber through the second chamber. Part of the first film and the second film between the first chamber and the second chamber and between the gas passage and a peripheral edge of the balloon are joined together to form a first weld portion and a second weld portion. The first weld portion is formed on an opposite side of the second weld portion with the gas passage sandwiched therebetween.

Abstract: A balloon can maintain a bent state even if a bent state-holding member is not used. A balloon includes two plastic films that are stacked and sealed at a peripheral edge. The balloon includes a first part, a second part, and a bending part that is situated between the first part and the second part. The bending part includes a gas passage through which the interior of the first part and the interior of the second part communicate with each other, and a bending sealed part that is formed by sealing the two plastic films situated opposite to each other in an inward area relative to the peripheral edge. An outer edge of the bending sealed part extends beyond the bending part so as to be situated within the first part and the second part.

Abstract: There is provided a port closing device for a compressor which is fixed to a housing of the compressor by a bolt and includes a packing and a cap. The packing closes a suction port or a discharge port formed in the housing. The packing has a first end, a second end and a peripheral surface formed between the first end and the second end. The first end of the packing has a flat seal portion that is in contact with a surface of the housing surrounding the port. The cap has a holding portion that presses the peripheral surface of the packing for holding the packing, and a pressing portion that presses the second end of the packing. The pressing portion of the cap has therethrough a hole.

Abstract: A suction throttle valve of a variable displacement compressor having a compressor housing includes a suction chamber, a crank chamber, an inlet, a suction passage, a valve body, a valve housing, an urging member, a valve chamber, and a communication hole. The valve body is provided for adjusting an opening area of the suction passage and movably arranged in the suction passage. The urging member urges the valve body in the direction that decreases the opening area of the suction passage. The communication hole is provided for connecting the suction chamber to the valve housing. An opening area of the communication hole is variable in accordance with the movement of the valve body. Accordingly, the opening area of the communication hole becomes maximum during the maximum displacement operation of the compressor and becomes reduced during the intermediate displacement operation of the compressor.

Abstract: An outer sheath of a shield wire is stripped by a predetermined length from an end of the shield wire to expose a knitted layer of the shield wire. A shield stopper is mated over the exposed knitted layer until the shield stopper abuts against a stripped end of the outer sheath. A metal shell piece is preparatorily mated over an inner sheath of the shield wire while the metal shell piece expands the knitted layer. The shield stopper is clamped by a clamp means, and the mated metal shell piece is pushed to engage with the shield stopper. In the engagement state, the shield stopper overlaps a forward end portion of the metal shell with the knitted layer therebetween. A first cutter is guided by a pipe member so that the first cutter engages with an outer peripheral surface of the second cutter. Thereby, the shearing movement of the cutters cuts the exposed knitted layer near a rear end of the shield stopper.

Abstract: A composition for a snow- or ice-accretion inhibiting member which has a static friction coefficient of less than 1.3 relative to snow having a temperature range of 0 to −10° C. The composition of the present invention can show not only a good snow- or ice-accretion inhabiting property upon snowfall but also an improved snow slipping-off property upon temperature rise.
