Presetting counter device for control of single or repeated actuation of a piece of equipment permits stopping of equipment action during continuous repeat action thereof if required, and always resets a display means for an indication of the number of times the device is required to be actuated to "1" when the equipment is thus stopped and after single or repeated actuation of the equipment, whereby manual resetting action by a user is unnecessary. As the device requires manual actuation only of a resetting switch, an initial count means for specifying a required number of actions during actuation of the equipment, and a start switch, equipment control with the device is extremely simple.

In operating an apparatus provided with a plurality of various component devices incorporated therein, it is necessary to provide some type of sequential controller when the plurality of the devices are required to be operated sequentially for predetermined periods, independently of each other. The improved type of sequential controller of the present disclosure has a plurality of cam plates each of which is provided with switch units for controlling the operating periods of the various component devices, and which are rotated by a driving means, a lock claw for engaging with the cam plates and a controller for controlling the movement of the lock claw, so that the predetermined rotation of the cam plates controls the operating periods of the various devices.

The present invention is an electrophotographic copying apparatus which includes a group of switches disposed along the path of the copy paper. These switches are so arranged as to control the functions of corona charging, exposure and aligning the forward edge of the image formed on the photoreceptor with the leading edge of the copy paper, while the starting of the transfer device and the function of the copy paper separation device are controlled through a control cam which is driven by actuating signals produced by one of these switches. Since the developing and transfer functions are arranged to be suspended by a drum cam rotating as one unit with the photoreceptor drum, the possibility of copy paper jamming is decreased to a large extent through reduction of the number of switches employed, while undesirable developing and transfer at the slot portion or seam portion of the photoreceptor are advantageously eliminated.

The invention relates to a receiver-drier for use in an air conditioning system. This receiver-drier has (a) a lower portion defining a lower chamber in the receiver-drier; (b) an upper portion defining an upper chamber in the receiver-drier; and (c) a strainer for removing foreign particles from the refrigerant. The lower portion has an inlet for allowing the refrigerant to flow into the lower chamber and an outlet for allowing the refrigerant to flow out of the lower chamber. Each of the inlet and the outlet is formed at a bottom of the lower portion. The upper chamber is on top of the lower chamber and is charged with a desiccant for removing moisture from the refrigerant. The strainer is disposed at a position in a flow of the refrigerant from the inlet to the outlet.
