PURPOSE:To keep rod operating speed constant regardless of any temperature change in the operating oil by changing, in response to the operating oil temperature, the duty ratio for a control valve which is subjected to a duty control in order to control the flow of the operating oil to be supplied to a hydraulic cylinder. CONSTITUTION:CPU 36 decides the operating speed of a rod 10a in a hydraulic ...

PURPOSE:To reduce the cost by setting speed change initial oil pressure in an automatic speed change gear corresponding to various kinds of engines to be applied to various kinds of engines. CONSTITUTION:When a signal for starting speed change from the first speed to the second speed is transmitted by an electronic control unit to switch a solenoid valve, the imitial duty ratio (d1) of the solenoi...

A system for handling a flexible thin wall tubular extrudate (17) and for cutting-off a predetermined length sleeve (18) of the extrudate (17) and delivering the sleeve (18) to a discharge station (23). A pair of grippers (7,8) is movably mounted on carriage assemblies (5,6) which move the grippers horizontally and transversely with respect to the axis of the extrudate (17). The leading gripper pr...

PURPOSE:To improve molding production of a small tire by arranging a molding bladder device on the external diameter of a molding drum flange so that the front end of the bladder is mounted on the surface of the concave part to fix a bead when the diameter of the molding drum is expanded. CONSTITUTION:A carcass member K is wound about the external circumference of a molding drum flange 9, the mold...

An uncured polyurethane coating formed by applying polyurethane paint containing isocyanate prepolymer on a substrate is cured by a method which comprises applying a catalyst (cure accelerator) on the uncured polyurethane coating and subsequently exposing the polyurethane coating to a heating atmosphere of 60 DEG to 100 DEG C. By this method, the reaction of urethanation explosively proceeds and...
