Title: Apparatus for mounting blanket of printing cylinder
Inventor: HATTORI HIROTAKA
IPC: B41F27/12
Filed: 1988-02-24
Abstract: PURPOSE:To enhance the quality of printed matter by mounting a blanket to the peripheral surface of a printing cylinder in a tensioned state by receiving the free end part of the blanket fixed to the peripheral notch of the cylinder at one end thereof in a receiving trough having a semicircular arc cross-section and deflecting the blanket protruding from the receiving trough in the direction of the fixing member within the notch by a deflection shaft. CONSTITUTION:One end of a blanket 17 is fixed to the peripheral notch 4a of a printing cylinder and the part other than the fixed end thereof is received in a receiving trough 21 in a wound state so that the rear thereof is turned inwards. Thereafter, the blanket 17 issued from the receiving trough 21 is deflected by a deflecting shaft 23 and guided to the fixing member in the notch of the cylinder to be fixed thereto. When the printing cylinder is revolved in this state, the blanket is closely brought into contact with the inside of the receiving trough by elasticity to receive resistance by the deflecting shaft. As a result, the blanket can be wound around the peripheral surface of the printing cylinder in a tensioned state without being slackened even if not pressed by a hand and, thereafter, the other end of the blanket is fixed to other winding bar which is, in turn, revolved to mount the blanket to the peripheral surface of the printing cylinder in a close contact state.

Abstract: PURPOSE: To provide a smooth start of a compressor by performing a stand-by control during a predetermined period of time when the temperature of the compressor is not higher than the freezing temperature of a lubricating oil. CONSTITUTION: When a compressor is not in an operation-on status, a compressor temperature Ti input from a microcomputer 6 on the side of outdoor equipment through a compressor thermistor 10 is read and compared with a predetermined lubricating oil freeze temperature Ta.
