摘要： PURPOSE:To simultaneously separate and release a plurality of tension rolls from a drive roll by a method wherein a feed drive part comprises a drive roll and a tension roll axially mounted on a plurality of link arms, and the upper end of each link arm is coupled to the working arm of a pressure working part arranged at a side through a regulating rod with a spring. CONSTITUTION:A feed drive part to feed a band steel in a state to nip the band steel comprises a drive roll 3 and a tension roll 4 axially mounted by means of a plurality of link arms 8 arranged on the outer peripheral surface of the drive roll 3. The upper end of each link arm 8 is coupled to the working arm 29 of a pressure working part 20, arranged to a side, through a regulating rod 30 with a spring. This constitution simultaneously performs high-efficient separation release and pressure adhesion operation between the pressure working part 20 and each tension roll 4 through operation of the pressure working part 20 when a band steel is nipped by the drive roll 3. Further, since a plurality of tension rolls 4 are nipped through lever operation, no slip occurs even when movement and a stop are repeated at a high speed.

摘要： PROBLEM TO BE SOLVED: To crush only concrete sections without shredding the reinforcing bars of a welded structure of a structure embedded with the reinforcing bars of the welded structure. SOLUTION: This concrete crusher is provided with rotary drums 3, 3 which rotates reverse from each other in juxtaposition. The outer peripheries of these rotary drums 3 are projectingly provided with circular tooth trains 11 constituted by successively connecting 4 to 8 crushing teeth 10 of prescribed shapes in a circumferential direction. These circular tooth trains 11 forms V-shaped tooth grooves 12 between the adjacent crushing teeth and are alternately formed at a prescribed pitch along the axial direction of the rotary drums 3. The contours of the crushing teeth consist of arcuate bottom lands in contact with the outer peripheries of the rotary drums 3, arcuate tooth crests along the bottom lands, dedendum flanks of which the bottom ends intersect with both ends in the longitudinal direction of the bottom lands along the radial direction of the rotary drums 3 and oblique tooth surfaces forming the tooth grooves by intersecting with both ends in the longitudinal direction of the tooth crests from the top ends of the display flanks thereof. These oblique tooth surfaces intersect with both flanks of a lightweight concrete structure W of a cubic shape having a plate thickness of 150 mm as the raw material to be crushed respectively at a bite angle of 15 to 25 deg. at the ridge parts with the dedendum flanks.

摘要： PURPOSE:To feed a band steel under a constant contact pressure at which a slip hardly occurs by a method wherein a plurality of tension pulleys are radially arranged and brought into pressure adhesion to the outer periphery of a reel type drive roller through their own spring pressures. CONSTITUTION:A band steel unreeled from the band steel feed reel 33 of a band steel feed mechanism part 30 is fed to a feed drive part 34 through an upper mark forming device 35 after the passage of it through a guide pulley 48 having a detecting sensor. The band steel is wound around a drive roller 40 at a high angle enough for contact with approximately the half peripheral surface of a drive roller 40 from the band steel introduction side A. With this state, the band steel is nipped by means of a plurality of tension pulleys 41a-41n on which pressures by respective springs are applied and a given drive force is exerted. Thereafter, on the band steel feed side B, the band steel is wound around a band steel winding reel 36 after the passage of it through the same guide pulley with a detecting sensor as the guide pulley 48.

摘要： PURPOSE: To provide a fog removing device requiring little power consumption at a relatively low voltage and having high safety by using the same principle as the high-voltage applying method. CONSTITUTION: An electric wire electrode 12 covered with an electric insulator is wound on an electric insulating substrate 10. The substrates 10 are arranged in parallel at the prescribed intervals, one end of each electric wire electrode 12 is connected to each power source section, and the other end is hooked on each substrate 10. A voltage is applied to each electric wire electrode 12 from each power source section, particles of fog are connected and dropped by the action of the electric field generated between the substrates 10, and the fog is removed.
