Abstract: A through-hole of a hydraulic chamber is provided on an input side of a thrust expansion device in accordance with rod diameters of various actuators on the input side, and an input rod of an air cylinder or the like is inserted therein. Thus, a thrust expansion mechanism operates. An input-side actuator attaching portion of the thrust expansion device is configured such that parts can be changed according to a fixing method of various actuators and a rod shape. It is possible to freely change a thrust expansion ratio by changing a cross sectional area of the input rod. A stroke of an output-side rod can be changed by changing an input stroke of the input-side actuator. According to the thrust expansion device, various inexpensive commercially available actuators can be easily attached and replaced by being separated and independent from the input-side actuator.

Abstract: A timepiece capable of selecting a timepiece mode and a chronograph mode includes an hour hand and a minute hand which indicate current time in a case where the timepiece mode is, selected. A main control unit performs control so as to start measuring time by simultaneously starting hand operations of the hour hand and the minute hand in a case where the chronograph mode is selected. When the hand operation of one of the hands is stopped, the control unit performs control so as to indicate the time when the hand operation of the one hand is stopped, and to continue to measure the time by continuing the hand operation of the other hand.

Abstract: An inner cylinder inside an outer cylinder is disposed to be coaxial to an air pressure supply rod inside the inner cylinder. A first piston is disposed between the air pressure supply rod and the inner cylinder, a pneumatic chamber is disposed on a side of one surface (hydraulic surface) of the first piston in the inner cylinder, and a first hydraulic chamber is disposed on a side of the other surface. A second piston is disposed between the outer cylinder and the inner cylinder, and a second hydraulic chamber is disposed on a side of a surface of the second piston which is provided in the same direction as the hydraulic surface of the first piston in both of the cylinders. The inner cylinder is provided with a communication hole for transmitting a negative pressure along with movement of oil with which the first hydraulic chamber and the second hydraulic chamber are filled. In this configuration, it is possible to shorten an overall length of a fluid pressure cylinder.
