    • A structure for preventing an image being shaken when a vibration occurs in an optical system so as to stabilize the object. A compensating lens is incorporated in a third lens group of a lens barrel constituting the optical system. The compensating lens is allowed to move within the third lens group and only in a direction perpendicular to the optical axis. A pulse motor mounted on a fixed barrel drives the compensating lens. The rotation of the pulse motor is converted into the rotation of an interlocking lever. The interlocking lever is a straight bar having an uncircular sectional configuration. A driving lever having approximately the same configuration as the sectional configuration of the interlocking lever is slidably inserted thereinto. The driving lever rotates together with the interlocking lever. One end of the driving lever penetrates through the frame of the third lens group, thus contacting the head portion of a pin which presses the compensating lens. When the driving lever rotates, the compensating lens is pressed through the pin. At a position opposed to the pin, a plate urged by a leaf spring supports the compensating lens. A mechanism for driving the compensating lens is provided in x-direction and y-direction with respect to the compensating lens. When the driving lever rotates in the opposite direction, the compensating lens is moved to the initial position by the elastic force of the leaf spring.

    • A rotary compressor for compressing a refrigerant gas has a by-pass port and a control valve means. The by-pass port communicates at one end with a suction chamber containing the gas to be compressed, and at the other end with a compression chamber wherein compression of the refrigerant gas is in progress. The control valve means includes a valve spool accommodated in a chamber formed in a front side plate of the compressor and movable between its full-load position, where a gas suction port is opened to the compression chamber while the by-pass port is closed, and its partial-load position where the former is at least partially closed while the latter is opened. The valve spool is normally biased to its partial-load position. During operation of the compressor, the valve spool is placed under the influence of a first pressure of the gas acting to urge the same towards its said full-load position, and to a second pressure of the gas to urge the same towards its said partial-load position. The spool is shifted automatically to its partial-load position when the difference between these first and second pressures is decreased with a drop of cooling load. The compressor of the invention further comprises a flow control means for regulating the flow of the gas into its compression chambers in the event of a rapid increase of compressor speed.
