IPC: F15B15/14
Filed: 1998-10-01
Abstract: PROBLEM TO BE SOLVED: To prevent a damage due to the biting of a inner lip of a rod packing under operating hydraulic pressure into a joint of an operating rod when the joint of the operating rod passes through the rod packing. SOLUTION: Two rod packings, an inner rod packing 7 and an outer rod packing 8, are provided in parallel in the axial direction on a rod guided part 4. The rod guide part 4 guides a piston rod 2 having a joint 9 in the middle. A sliding gap 6 formed between the two rod packings is communicated with a reservoir 12, and an operating fluid chamber 14 is sealed by the inner rod packing 7, when the telescopic motion of the piston rod 2 does not cause the affect of the joint 9 of the piston rod 2 over the rod packings 7 and 8. The sliding gap 6 has been switched in advance to communicate with the operating fluid camber 14 to maintain the pressure of the sliding gap 6 at the operating fluid pressure and also to seal the sliding gap 6 with the outer rod packing 8 before the joint 9 of the piston rod 2 passes through the inner rod packing 7.  The sliding gap 6 is switched back from the communication with the fluid camber 14 to the communication with the reservoir 12, and the inner rod packing 7 seals the operating fluid chamber 14 after the joint 9 moves beyond the inner rod packing 7.

Abstract: PROBLEM TO BE SOLVED: To judge whether or not the apparatus is wetted without checking the inside of the apparatus from the outside of an apparatus by sticking a seal with color-change ink by water-infiltration to a necessary position of the apparatus. SOLUTION: On a back side of a case 2 of a portable phone 1, a notch part 6 is formed for a rechargeable battery.

The picker 1 is expanded in its radial direction and pressed against the inner circumferential surface of the bobbin 2. Then, the bobbin 2 is picked by the picker 1, and the bobbin 2 is elevated between grippers. Then, the grippers are closed, the bobbin 2 is held between the grippers, and lowered. Though the bobbin 2 is pressed down by a sleeve 4 and a bush 7, the residual yarn in the bobbin is hooked by the grippers, and is not lowered. Thus, the residual yarn is peeled off from the bobbin 2, and sucked and removed by a suction pipe.

IPC: C04B38/00
Filed: 1991-10-25
Abstract: PURPOSE:To obtain a porous material capable of high-temperature use for a long period without disappearance of fine pores by applying a specified sealant to pores of an inorganic porous material and subsequently calcining it. CONSTITUTION:After applying a sealant composed of silica gel, alumina gel or silica alumina gel to pores of an inorganic porous material, the sealant is calcined at about 350-600 deg.C. In the above-mentioned process, a gel having 10-30Angstrom  average pore size is formed by applying the sealant to the pores of the inorganic porous material and fine pores having 10-20Angstrom  average pore size are formed in the inside of the sealant by calcination at about 350-600 deg.C after application. The porous material is, after application of the sealant and subsequent repeated calcination operations, further fired at about 700 deg.C to stabilize the porous state of the sealant. If the resultant porous material is used as a gas separation membrane, a high-performance and high-permeation- speed separation of a mixture gas is possible without reduction of the performance even after long-term operation at high temperatures.
