Abstract: To detect humidity, used are a first series connection circuit connecting a thermistor and a fixed resistor via a node, a second series connection circuit connecting a resistance change type humidity sensor and the thermistor via the node, and a third series connection circuit connecting the humidity sensor and the fixed resistor via the node. A predetermined voltage is applied across the first circuit to detect a first voltage indicating temperature through the node, and secondly across the second circuit to detect a second voltage indicating a first humidity through the node, and finally across the third circuit to detect a third voltage indicating a second humidity through the node. Then, the first voltage is compared with a reference voltage and judgment is made, based on a comparison result, to determine which of the second voltage and the third voltage is relevant to use as a basis for outputting the humidity as detected.

Abstract: An automatic air balancer system capable of maintaining various kinds of load at a predetermined position and then moving the load at a desired speed, or applying a desired mechanical force to various kinds of object. The system includes a device for controlling the pressure at one end side of a balance cylinder to a desired level by a first pressure control valve and for controlling the pressure at the other end side of the balance cylinder to a predetermined level by a second pressure control valve, and a device for obtaining a balance pressure signal for the balance cylinder. Another signal is added to or subtracted from the balance pressure signal, and the resulting signal is input to the first pressure control valve.
