Abstract: A leaf spring load measuring device of the present invention comprises a weighing mechanism, a measuring mechanism, a metering mechanism, and a control mechanism. The weighing mechanism applies a load heavier than a working load to a leaf spring, thereby bending the leaf spring in its thickness direction, and maintains the resulting state for a predetermined hold time. The measuring mechanism measures a load value of the leaf spring in a manner such that the spring is subjected to a load within a range of the working load. The metering mechanism meters a displacement of the spring when the load value is measured. The control mechanism controls the weighing mechanism, the metering mechanism, and the measuring mechanism, and has a timer function to meter the hold time.

Abstract: A slewing control device for a hydraulic slewing crane adapted to supply a discharge oil from a hydraulic pump through a slewing control valve to a slewing motor and control a rotational direction and a rotational speed of the slewing motor. The slewing control device includes a brake pressure control valve for variably controlling a discharge pressure of the slewing motor, an acceleration pressure control valve for variably controlling a suction pressure of the slewing motor, and a controller for outputting to both pressure control valves a pressure control signal to be determined according to an operational condition of the crane upon braking of a slewing body and controlling both the discharge pressure and the suction pressure of the slewing motor to control a pressure differential therebetween. Accordingly, even when a braking torque is small, the slewing body can be smoothly braked to be stopped at a target position accurately with no oscillation of a suspended load remaining.

Abstract: In the case of thickening a feed resin without pre-drying, a device is taught to enhance the thickening effect. The device includes a chamber 4 having a mixing rotor therein for continuously mixing a resin between a feed port 2 and a discharge port 3. A plurality of vent ports 7 connected to vacuum pumps 8, 9 are provided for reducing the pressure in the chamber. An element, e.g. a screw feeder 10, is provided for introducing a viscosity-increasing chemical agent into the chamber. The screw feeder is isolated from the reduced pressure areas of the chamber by elements 35, e.g. reverse screw flights of the rotor. In operation, feed resin from a hopper 6 enters the chamber through port 2 and is dehydrated while being continuously mixed in a drying section 14 via vents 7. After addition of the chemical agent, the resin is continuously mixed in a thickening section 15 while being deaerated.

Abstract: A polyester resin is thickened in a chamber 4 by first introducing the feed resin through a port 2 and dehydrating in a drying section 14 under reduced pressure. A chemical agent is then added to the dehydrated feed resin and mixed therewith in a thickening section 15. The mixing occurs while deaerating under reduced pressure. The chemical agent functions to either increase the viscosity of the feed resin or suppress the lowering thereof.
