摘要： An automatic transmission for a vehicle which automatically carries out transmission control in relation to the running of the vehicle. In addition to an operation lever (111, 112) such as a select lever, a hold switch (180) is provided for informing an automatic transmission controller (130) of the need for a hold operation to automatically hold the currently selected gear position (speed step) of the transmission (160). The hold operation is executed by the controller depending upon the operation of the hold switch. When the forward-reverse switching is effected after the hold switch is operated, furthermore, the transmission at the time of start is once switched (shifted) to the second speed step forcibly. As the desired speed step that is held is reached accompanying the rise of the vehicle speed, this speed step is automatically held as a result of the hold operation. Therefore, even vehicles for construction machinery such as wheel loaders are permitted to execute the operation efficiently and smoothly.

摘要： This invention relates to a temperature controlling apparatus and its method for keeping constant a spigot gap of molds of a plastic compression molding machine, and controls the temperatures of structural components such as a bolster, a slide, frame, and the like, that affect the spigot gap of the molds so that their dimensional changes calculated from their dimensions and thermal expansion coefficients are below an allowable value of the spigot gap. Fluid passages are formed at least on the bolster for supporting the molds and on the slide, circulation means of an operation oil used for a lift cylinder is disposed in these fluid passages and temperature control means for attaining the control temperatures described above is disposed at the intermediate portion of the circulation means, so that the operation oil is circulated while being controlled to the set temperatures of the structural components. The temperature control means can be composed of a heat-exchanger and a flow rate regulating valve. According to this structure, a mold gap such as a shut height and a shear edge clearance can be controlled to a constant value, the change of clearance with each molding cycle is eliminated and stable molded articles can be produced. At the same time, molded articles having stable quality and free from molding change with time can be obtained.

摘要： This invention relates to a hydraulic circuit apparatus which introduces a load pressure of one of a plurality of hydraulic actuators and thus improves temporarily the function of one pressure compensation valve in order to prevent the load pressure of one hydraulic actuator at the start from becoming abnormally high and to prevent relief of the pressure oil from a safety valve when a plurality of hydraulic actuators are operated simultaneously, supplies large quantities of pressure oil to the actuator connected to this pressure compensation valve and improves its operation speed. This hydraulic circuit apparatus is equipped with a compensation pressure change-over valve (26) for supplying normally the highest load pressure to a spring chamber (9a, 10a) side of each pressure compensation valve (9, 10) and for supplying the load pressure of each hydraulic actuator (5 ∼ 6) connected to each pressure compensation valve to the spring chamber side of each pressure compensation valve when either one of the operation valves (3 or 4) is changed over at a full stroke.

摘要： This invention is directed to provide pilot valve which is compact in size, does not easily cause an erroneous operation but can be produced at a low cost. In this pilot valve, a downwardly spherical recess (23) is formed in a disc (14) for transmitting the motion of a lever (15) to a piston (8) for sliding a spool (4) which cuts off/sets up communication between an inflow port and an outflow port (3) that are formed inside a valve main body (1) and a spherical protuberance (20) is formed on the valve main body side in such a manner as to be capable of fitting and rocking to the spherical recess. Furthermore, a lever fitting shaft (13) is constituted in such a manner as not to rotate with its axis as the center when the lever is operated.

摘要： Control of shifting into a lower gear of a wheel loader when a bucket is thrust into an object of excavation, such as ground or mountain, wherein angles of a boom and a bucket are set respectively at an angle suitable for excavation in advance. During a forward movement toward the earth or mountain, when both of the boom and bucket reach said set angles, said movement is detected, whereupon the current gear is shifted automatically, based on the outputs of said detection, into a lower gear having a larger tractive force.
