摘要： One or more pantographs are connected below a working base and are connected with a main cylinder horizontal or inclined in respect to a supporting base so as to be driven to be extended or contracted. One or more comparatively short auxiliary telescopic cylinders are erected below the working base. During the initial phase of upward movement of the working base the auxiliary cylinders will act directly to push up the working base and, when it has been elevated to a predetermined height, the pushing force is shifted to the main cylinder so that the working base may be further elevated through the pantographs.When the working base is lowered, the pantographs and main cylinder will be compactly folded.

摘要： A closed loop air-to-fuel ratio control system having an oxygen responsive sensor and a feedback circuit is disclosed. The sensor is disposed in an engine exhaust passage to produce a voltage indicative of the oxygen concentration in the exhaust gas. This voltage is integrated in the feedback circuit to cause the mixture air-to-fuel ratio to be corrected in response thereto. The integration is controlled by the integration controller to shift the mixture air-to-fuel ratio to the one other than the stoichiometric ratio. This integration controller can be made responsive to specific engine operating conditions such as throttle valve movement.
