An apparatus 1 for continuously forming an FRP square pipe comprises a long core 10 for laminating prepreg sheets, and to this core 10 are fed prepreg sheets from prepreg laminating devices 20, 30, 40 and 50 with a release film interposed between the core, so as to be laminated into square pipe form. The core 10 has an outer diameter size smaller than the inner diameter size of the square pipe to be formed. The outer circumference of the square pipe is wrapped with a tape-like film fed from a tape-like release film wrapping device 200 in spiral fashion, and the work is heated and pressed in a hot press 100. The work is then subjected to additional heating in a postcure furnace 110 to form the FRP square pipe. The square pipe is intermittently pulled by a puller 130 disposed downstream of a clamp 120. The pipe is then cut to predetermined lengths by a cutter not shown to be completed as a product.

A device to control vertical vibration of a building caused by seismic disturbance. Air springs are positioned and secured between the building foundation and the building superstructure to attenuate vertical vibration of the building. Vertical support rails are secured to the foundation and/or to the building superstructure on opposite sides of, and adjacent to, the air springs. Horizontal connecting brackets are rigidly secured to the air springs and slidably secured to the adjacent rails. The brackets restrain horizontal deflection of the air springs without interfering with vertical reciprocation of the air springs.

A side-entry specimen holder for use with a transmission electron microscope. The holder comprises a specimen-holding plate and an insertion rod. The holding plate is provided with a hole permitting passage of the electron beam produced inside the microscope. Either a specimen or a piece of mesh on which a specimen is placed is held inside the hole. An engaging hole is formed at one end of the holding plate. The insertion rod has a pin at its front end. The pin is engaged in the engaging hole to detachably hold the holding plate. Thus, the insertion rod is coupled to the holding plate.

In a continuous molding apparatus equipped with a long core 10 having a curvature disposed on a plane, a release film supplied from a lower release film feeder 20 is sent onto the core 10, and prepreg sheets supplied from a prepreg sheet feeder 30 are laminated thereon and preformed. A release film supplied from a release film feeder 40 is disposed on top of the laminated body, before the body is sent into a hot press 50. A puller 60 moves the laminated body without loading tension thereto. The laminated body enters a postcure device 70 in which thermosetting of the material is completed.

The present invention treats crushed pieces of a nonmetallic honeycomb panel together with a process water under high-temperature and high-pressure for a predetermined time so as to separate components. Water or alkali-added water is used as process water. The method comprises a first process for treating the crushed pieces for a predetermined time with the water heated and pressurized to a subcritical range to hydrolyze aromatic polyamide, and a second process for treating the same with the water heated and pressurized to a supercritical range, wherein the aromatic polyamide is hydrolyzed and separated in the first process, and dehalogenation is carried out in the second process.

A holder support device in an electron microscope. The device has a detachable cylindrical holder extending along the X-axis. The holder support device permits the position of the inner end of the holder to be adjusted along the X-, Y-, and Z-axes and about the angular position about the X-axis. The support device has an inner cylinder rotatably held to an outer cylinder. The inner cylinder is provided with a holder through-hole and a pin guide hole. The holder is slidably held in the holder through-hole. The pin guide hole guides a pin on the holder when it is inserted into the holder through-hole. The outer cylinder is provided with a circumferential guide hole and axial guide holes.

A continuous forming method and device for an H-shaped FRP member for forming semi-hardened preimpregnated members produced by impregnating thermosetting resin to carbon fiber or glass fiber and the like into a predetermined H-shape. The forming device comprises of a device for mounting a plural number of bobbins having strip-shaped preimpregnated material spooled thereto, providing tension when pulling the impregnated material out from the bobbin. The device the shapes the preimpregnated material to a predetermined H-shape that feeds release films from four sides of upper, lower, left and right. The device then provides heat and pressure to the preimpregnated material from said four sides with a heating furnace for after-curing the preimpregnated material. The device then hauls and holds the preimpregnated material for cutting the cured product.

A device 1 for continuously manufacturing an FRP square pipe includes a core 10 having a long length for laminating prepreg sheets thereto, and prepreg sheets are supplied from prepreg-sheet laminating devices 20, 30, 40, and 50 to said core 10 covered with a release film, said laminated sheets laminated into the shape of a square pipe. Said core 10 has an outer diameter size smaller than the inner diameter size of the square pipe to be manufactured. A pre-expansion device 80 expands said laminated prepreg sheets to the shape of a square pipe having a predetermined inner diameter size, and a hot press device 100 heats and pressurizes the pipe. The pipe is then additionally heated in a postcure furnace 110 to complete the forming process. A pulling device 130 arranged downstream of a cramp device 120 pulls out said square pipe intermittently. A cutter not shown cuts said square pipe to produce the desired product.
