Abstract: PROBLEM TO BE SOLVED: To stably control boosting irrespective of an unevenness of clutch precision or a temperature characteristics of a directional control valve in a oil hydraulic circuit which selectively supplies pressure oil to a plurality of hydraulic clutches by operation of the directional control valve. SOLUTION: A pressure oil discharged from an oil hydraulic pump 44 passes through a pressure reducing circuit 45, and a part of it is supplied to a forward/ backward drive switching clutch 31 via an oil passage 49 and a solenoid-method directional control valve 46. A branch oil passage 52 is arranged in the oil passage 49, and a solenoid-operated proportional relief valve 53 is provided therein. The solenoid-operated proportional relief valve 53 is initially set so that a pressure oil supplied to the forward/backward drive switching clutch 31 is at a minimum operating pressure for a clutch piston when a solenoid 54 is off. The solenoid 54 is not turned on until a fixed time after the directional control valve 46 is switched.  After the clutch piston 41 or 43 of the forward/ backward drive switching clutch 31 reaches its stroke end, the solenoid 54 of the solenoid-operated proportional relief valve 53 is turned on to start a boosting control, thereby remarkably reducing a shock of connecting a clutch, and attaining a smooth boosting characteristic.

Filed: 1989-03-08
Abstract: PURPOSE:To control the thickness of a coating film to be constant by a method wherein the thickness of the coating film applied by a spin coating apparatus is detected to compensate the number of rotations of a spin coater. CONSTITUTION:With a spin coat process 1, a coating film is spin-coated on a wafer by using a spin coating apparatus. Further with a film thickness detecting process 2, a film thickness detector 12 is used to detect the thickness of the coating film applied on the wafer by the spin coating apparatus. Then with a film thickness adjusting process 3, the number of rotations of the spin coating apparatus is compensated according to the difference between the thickness detected by the film thickness detector 12 and the desired coating film so that the thickness of the coating film is adjusted to be desirable. The thickness of the coating film applied by the spin coating apparatus can thus be always controlled to be constant.
