Title: Hydraulic type valve driving device
Inventor: ARUDAA ROORANTO
IPC: F01L9/10
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To enable synchronous opening and closing of an intake valve and an exhaust valve under arbitrary conditions by providing a braking device for braking the retreat operation of a synchronous piston and a valve to the initial position and a hydraulic device for compensating a difference between the projected parts of shafts of two or more valves driven by a hydraulic driving device. SOLUTION: A hydraulic driving device to valves 11, 11' has a synchronous piston 12, and a spring 1211 disposed in a chamber 1210 can completely energize the synchronous piston 12 to the initial position. In order to prevent the synchronous piston 12 from smashing into the base 123 of a cylinder, the end part of the cylinder and the end part of the synchronous piston co-operate with each other to form a damper 124 as a braking device. The valve pistons 12, 13' are always brought into contact with the terminal ends of the valve shafts 112, 112' regardless of a difference between the projected parts H, H' of valve shafts 112, 112' by the supply of operating oil into a system. Thus, under arbitrary conditions, it is possible to ensure synchronous opening and closing of an intake valve and an exhaust valve.

Title: Measuring apparatus combined with gripper
Inventor: OONO RIYOU
IPC: B25J13/08
Filed: 1982-11-12
Abstract: PURPOSE:To reduce the working time by a method wherein dimensions of work is measured simultaneously with the gripping thereof in a robot hand or the like so that the work gripped is determined whether it is as specified or not based on the measured value to enable selection of work, assembly of normal work and other jobs. CONSTITUTION:A spring 62 always brings inclined surfaces 61 of detection elements 6 into contact with the inclined surface of a moving element 5. With the rotation of a motor 2, the detection elements 6 stick out inwardly or outwardly in the radial direction to press the outer circumference or the inner circumference of work, gripping it. The movement of the detection elements 6, namely, the angle of rotation of the motor 2 is detected with an encoder 1 to enable the measurement of the outer dimensions or the inner dimensions of the work. The rotation of the motor 2 is converted to an axial motion and then to a radial motion of the detection elements 6, which in turn, causes a reduction in the speed thereby enabling the dimensional measurement at a high accuracy.
