Filed: 1977-10-19
Abstract: PURPOSE: To prevent damage on a flexible disc by providing a member to position the flexible disc, a member to hold the moving position of a moving member, and a coupling member to cooperate with a door.   
     CONSTITUTION: A flexible disc 8 inserted into an opening 2 is quided by guides 21, 22 and groove 23, and rests in a driving apparatus 1. In this state, when an upper door 71 is lowered, a frame 3 rotates about a shaft 32, and this rotation is transmitted to a lower door 72 through a linkage or the like. Nearly in the center of the stroke of the two doors, a pawl 75 is engaged with a fitting part 79, and the doors keep the engaged state, resisting the force of a coil spring 33. At this time, since a shaft 42 supported by a clamp 4 moves in the direction towards the spindle 5, the clamp 4 secures the disc 8 while positioning the center of spingle 5 and central hole  in the disc 8 in coincidence. Thus, damage on a flexible disc may be prevented

Abstract: PURPOSE:To surely prevent a working surface of a conveyor belt from getting polluted with a fluid for sealing (and fluid for pressurizing), as the time goes on by providing a checking frame of low friction material having a pressurereduced adsorption hole on a bottom surface to the outer peripheral section of a pressurizing chamber where the pressurizing chamber is in contact with the surface of an upper conveyor belt. CONSTITUTION:A subject 3 to be compressed is inserted between endless steel belts 2a and 2b and pressurized and processed while being conveyed to the right. Fluid 6 for pressurizing injected in each of pressurized chambers 4a and 4b pressurizes endless steel belts 2a and 2b with a uniform surface pressure while circulating in respective pressurizing chambers 4a and 4b in a flow channel, and the subject 3 to be compressed is pressurized with a uniform surface pressure by the pressure force. At that time, to prevent the fluid for pressurizing in the pressurizing chamber 4a from leaking, the fluid for sealing fed to a periphery section 8a of respective pressurizing housing 8 adheres to a contact surface of the pressurizing chamber of the conveyor belt 2a little by little and leaks out. The leaked fluid is checked by a frame 9 provided on the outer periphery of the conveyor belt 2a. The fluid checked by said frame 9 and increased in its volume in the frame 9 is overflowed out of the sides 12a and 12b in parallel with the belt conveyor direction and flowed down out of the device through an inclined guide plate 13.
