Abstract: In an absorption chiller/absorption chiller-heater wherein a pressure rise preventing means such as a safety valve, rapture disk or breakable plate is disposed in a high temperature regenerator or in the refrigerant vapor piping from the high temperature regenerator, with the discharge opening of the pressure rise preventing means being open to the atmosphere, in order to prevent the pressure rise in the high temperature regenerator, the discharge opening of safety valve is connected to low pressure units such as the low temperature regenerator through pressure relief piping so that, when the safety valve is activated, the refrigerant vapor and absorption solution of the high pressure side will be discharged to low pressure units such as the low temperature regenerator designed so as to generally maintain a vacuum therein during operation.

Abstract: A floppy disc recording and/or reproducing apparatus comprises a loading mechanism which has a support member which is fixed to the frame and has cam levers pivotally supported thereon, where each of the cam levers have a second cam part, a cartridge holder which has a first cam part and is arranged movable in upward and downward directions of the apparatus under guidance of the support member, and a push-eject member which has third and fourth cam parts and an ejecting push-button. The push-eject member is movable in frontward and rearward directions of the apparatus under guidance of the frame or the support member. A sequence of operations are carried out when a cartridge which accommodates the floppy disc is placed onto the cartridge holder so as to load the cartridge with respect to a driving shaft.
