Title: Sealing structure for pneumatically hammering excavation machine
Inventor: KAWASAKI HIROYUKI
IPC: E21B7/124
Filed: 1989-11-08
Abstract: PURPOSE:To maintain tightness and prevent a drill from launching to incapability of functioning by forming a seal member of a bit shank slide part of a pneumatic hammering excavator from a deformable cylindrical film material, and fixing the ends to the periphery of the bit shank and the casing. CONSTITUTION:A cylinder made of elastic material is folded back to form a seal 20, and one end 20A is fastened to a bit 22 by a stationary ring 60 while the other end 20B is pinched by the bottom of casing 10 and a cover 64. Then, pressure air is fed to an air hammer drill 14 from an air supply pipe 54, and a piston 28 is moved up and down to strike the bit 22, and thereby rocked is excavated. When the bit 22 moves up and down, one end 20A of the seal 20 is moved up and down, and the seal 20 deforms in following-up after this motion. Now the folded-back part 20C rolls up and down and moves. This prevents intrusion of muddy water to the contact surface of the seal 20 with bit 22.

Abstract: PURPOSE:To suppress side reaction, by directly introducing cooling water into a thermal decomposition product and quenching the product in thermally decomposing a 1,1'-peroxydicyclohexylamine-containing solution in a thermal decomposition column while heating to provide the titled substance. CONSTITUTION:1,1'-Peroxydicyclohexylamine (PAX), together with a heated inert gas, preferably superheated steam, is sprayed from the top of a thermal decomposition column and superheated steam is then blown into the upper part of the column to keep the PAX at 400-800 deg.C and instantaneously achieve thermal decomposition reaction in the vapor phase. Cooling water at <=60 deg.C is subsequently sprayed from a spray nozzle provided at the lower part of the column thereinto to quench the resultant thermal decomposition reaction product to <=250 deg.C, preferably <=130 deg.C and take out a condensate containing the aimed substance from the column bottom. Yield is increased and carbonized substances formed by the thermal decomposition are simultaneously washed away by the cooling water. Thereby scaling can be prevented to perform continuous operation. The obtained product is used as a raw material intermediate for nylon 12.

Abstract: PURPOSE:To provide a micro actuator of a type which is capable of being super-miniaturized and drives an operator in reciprocation, by intercepting a space between an operation fluid housing space and an operater guide space by means of a piston liquid. CONSTITUTION:When light is projected to an operation fluid 4 through an optical fiber 5, carbon single fiber is heated and temperature rises. As the expansion coefficient of the operation fluid 4 is large, expansion and evaporation are carried out, and pressure is raised, and building-out from an operation fluid housing space SA1 is made, and flowing to a piston liquid housing space SA2 is realized, and mercury 1 (piston liquid) is pushed toward an operater guide space SA3, and although it tries to stay in the piston liquid housing space SA2, it projects into the operater guide space SA3 large. A work guide space is covered with teflon, and the mercury 1 projects so as not to touch the wall surface of the space SA3. As a result, a rod 3 is pushed out to the right, and a pulling coil spring 7 conducts power accumulation. Also, when light projection by means of the optical fiber 5 is stopped, the heat of the operation fluid 4 is irradiated to the open air through a copper pipe 2, and the operation fluid 4 is cooled, and its volume becomes small, and the mercury 1 is moved left.
