An operating apparatus 1100 of a brake apparatus 1001 for restricting rotation of a brake drum 1003 including an operating lever 1112 and an operation restricting portion 1120 is provided. The operating lever 1112 is supported to be able to operate in a movable range. The movable range includes: a brake release mode permitting rotation of the brake drum 1003 both in regular rotation and reverse rotation; and an auxiliary brake mode restricting only reverse rotation of the brake drum. The operating lever 1112 is urged in a direction reaching the auxiliary brake mode from the brake release mode in a normal state. The operation restricting portion 1120 restricts a movement of the operating lever 1112 reaching the auxiliary brake mode by being brought into contact with the operating lever 1112 in the brake release mode.

With the same screw diameter as in conventional screw extruders, the screw length is reduced, whereby the material residue is reduced, the throughput is increased, the screw motive power is reduced, the temperature control is facilitated to prevent rubber scorching, and extrusion molding of a vulcanizalbe rubber composition is made possible at a lower temperature. In a composite extruding apparatus of rubber, a gear pump 20 is connected to a tip end of a screw extruder 10 via a screen mesh 14 having a breaker plate 15, and a die head 24 is connected to an ejecting side of the gear pump 20, wherein the screw extruder 10 plasticizes a fed rubber composition G mainly by friction with an inner surface of a barrel 12 and by heating from outside and extrudes the rubber composition G from the screen mesh 14 to a space on an inlet side of the gear pump 20; the screen mesh 14 rectifies the rubber composition G passing through the screen mesh 14 towards the gear pump 20 while stirring and plasticizing the rubber composition G by friction and shear; and the gear pump 20 further stirs and platicizes the ruber composition G, which is fed to the space on the inlet side, by shear and compression, and gives a forcing pressure to the die head 24.

A dust-proof boot comprising an internal engaging ring extended from one end of an expansible bellows portion and an external engaging ring provided upwardly thereof and capable of being spread is provided at an extended base of the internal engaging ring with an air flow port for guiding pressure from the inside of the bellows portion into the internal engaging ring. In mounting the dust-proof boot on a support provided with a guide hole, the internal engaging ring of the dust-proof boot is fitted into an internal groove of the support, after which compressed air is supplied from the interior of the bellows whereby the compressed air spreads the external engaging ring via the air flow port and the external engaging ring is fitted into an external groove.
摘要:
A continuous cold rolling and annealing apparatus for a steel strip so that interruption of a cold rolling mill part does not directly cause a continuous annealing furnace part to be interrupted, in which apparatus at least one cold rolling mill is located upstream of the entrance of a continuous annealing furnace and an intermediate reel for supplying a spare steel strip coil to said continuous annealing furnace, is arranged between the cold rolling mill and the continuous annealing furnace.

There is provided a process for producing an amide compound having an excellent harmful arthropod-controlling activity and represented by the formula (III): wherein R1, R2 and R3 independently represent a C1-C6 alkyl group optionally substituted with at least one halogen atom etc., R4, R5, R6 and R7 independently represent a halogen atom etc.
摘要:
A joining link, a strut, and first and second expansion levers constitute an expansion and contraction device. At the time of the braking, the proximal end portion of both of the expansion levers are mutually pressed from the opposite sides by first and second pressing members constituting a driving device. The reaction due to the braking is offset by the joining link portion, whereby a large force is not applied to the back plate or the like.
