Title: Multistage double-acting hydraulic cylinder unit
Inventor: TAKOYA TETSUZOU
IPC: F15B15/16
Filed: 1982-10-27
Abstract: PURPOSE:To reduce a shock at the time of switching an operation by substantially equalizing each effective area on a backward side of each movable cylinder, and interposing a pressure compensating flow control valve in a hydraulic circuit to make the operation speed of the cylinder substantially constant. CONSTITUTION:Each effective area on backward side is substantially equalized by considering the area of backward side oil chambers 12, 13 of respective movable cylinders 4, 5 and the area of a feed pipe 9. A multistage double- acting hydraulic cylinder is reciprocated by switching a direction changing valve 23 of a hydraulic circuit, and the speed of such movement is adjusted by a pressure compensating flow control valve 24a at the forward movement, and adjusted by a pressure compensating flow control valve 24b at the backward movement. Since the effective areas on the backward movement side of respective movable cylinders 4, 5 are substantially equalized, even if the respective movable cylinders 4, 5 are sequentially switched and operated, the driving speed of a load can be kept substantially constant. Therefore, a shock produced at the time of switching the operation of each movable cylinder can be reduced remarkably.

Title: Transmission
Inventor: NAKAGAWA KAZUNARI
IPC: F16H13/08
Filed: 1988-07-31
Abstract: PURPOSE:To provide a transmission which facilitates the micro adjustment of speed change ratio and gives a large speed change ratio with a miniature size, by providing such an arrangement the peripheral speeds of large and small diameter parts of a roller which rolls on a stationary circumferential surface are transmitted respectively through two kinds of rotary shafts. CONSTITUTION:When rollers 2 roll on a stationary circumferential surface E, large and small parts C, B of each roller 2 perform integrally planetary motion with different peripheral speeds at their peripheries, due to a difference in diameter therebetween, and the peripheral speeds are transmitted respectively through two kinds of rotary shafts 3, 4 which are therefore rotated with a variable rotating ratio due to the dimen sional relationship therebetween. Further, since the diametrical dimensions can be set continuously, micro adjustment of rotating ratio can be made continuously. Thus, the speed change ratios of both rotary shafts 3, 4 are functions of the two diametrical dimensions of the rollers 2 as parameters. The values of the functions show asymptotic nonlinear characteristics when the rollers 2 carry out planetary motion. Accordingly, with the use of a range in which the speed change ratio on the characteristic curve thereof abruptly changes, a large speed change ratio may be obtained without increas ing the size of the transmission.
