Abstract: PROBLEM TO BE SOLVED: To smoothly perform speed control of a hydraulic actuator whatever operating amount from an operating means, by correcting a command function to a pressure reducing means so that a maximum value of the output corresponding amount corresponding to output pressure of the pressure reducing means may fall in the detected input corresponding amount to the pressure reducing means. SOLUTION: Input pressure of an electromagnetic proportional pressure reducing valve 5, to be supplied from a control valve 4 is detected, and a current command is corrected according to the detected input pressure. When input pressure detected by a pressure sensor 6 is supplied to a controller 7. When the input pressure is supplied from the pressure sensor 6, the ratio of the input pressure detected by the pressure sensor 6 to oil pressure appropriate to a case where the operating amount of a operating lever 3 is maximum is calculated. A current command to be output from the controller 7 to the electromagnetic proportional pressure reducing valve 5 is corrected according to the operation of a speed trimmer 8. Whatever operating amount the speed trimmer 8 has the speed of a hydraulic actuator can be adjusted.

Title: Wood club head of golf
Inventor: KATAYAMA YUTAKA
IPC: A63B102/32
Filed: 1990-11-29
Abstract: PURPOSE:To lower the contact resistance against the ground and the lawn of the sole part by maintaining width of the sole face against width of a head in a specific relation, and also, forming a shape extending from the sole face to the back end part of a golf club in a desired R shape. CONSTITUTION:In a wood club head W1, it is formed by maintaining a relation of head width L1, that is, length (length between A-B') between the face and the back, and sole width L2, that is, length (length between B-B') seen in the direction of head width of the sole face, in a relation of L2<=1/2L1. Also, a shape extending from the sole face to the back end part of the club is formed in a desired R shape. In such a way, contact resistance of the sole face against the ground and the lawn, etc., is extremely small, therefore, an easily swingable club is obtained. Also, since the sole face is small, probability of a collision of the sole face and the ground is low, and possibility of generation of duffing becomes very small.
