摘要： When a gradient of fastening torque for a bolt decreases by a certain amount from its maximum value, the bolt is further turned by a specific angle and the true or false of its yield point is detected based on the variations of torque, or torque gradient before and after this further bolt turning so that bolt fastening will be terminated only when true yield point has been detected.

摘要： A liquid crystal display for a laser marker for attaining a higher printing speed, characterized in that a liquid crystal display screen (10) is divided into a first zone (10a) where a sub-scanning is first performed and a second zone (10b) where a sub-scanning is performed following the first zone (10a) sub-scanning, that switching of display is performed independently for each of said first and second zones (10a, 10b), and predetermined voltages are applied, respectively, to row and column electrodes after those row and column electrodes are grounded, whereby display switching processing can be performed independently for each of said first and second zones. Completion of the sub-scanning of the first zone (10a) is detected by a position detecting means, and when such a detection is done, switching of display in the first zone (10a) is independently performed. In addition, when the position detecting means detects the completion of sub-scanning of the second zone (10b), switching of display in the second zone (10b) is performed independently.

摘要： A hydraulic oil amount change-over controlling device for a hydraulic excavator adapted to set an oil amount at an optimum level by controlling through load-sensing a hydraulic pump by in turn setting the excavator to a low-horse power mode for an operation such as breaker work performed with less oil amount than for a normal digging operation with an engine for driving the hydraulic pump being driven at revolutions permitting small fuel consumption. The device of the present invention comprises a variable-capacity hydraulic pump (2), an engine (1) for driving the hydraulic pump, an actuator (3) driven by the hydraulic pump, an operation valve (4) installed on a pipeline between the hydraulic pump and the actuator, and load-sensing controlling devices (7, 8) for the hydraulic pump, and further a controller (30) for receiving signals fed from a sensor (25) for sensing the capacity of the hydraulic pump, a sensor (26) for sensing the number of revolutions of the engine, a sensor (27) for sensing the hydraulic pressure of the actuator, and operation mode change-over devices (17, 23), respectively, calculating a control signal allowing the engine to be driven at a predetermined horse power designated by the operation mode change-over devices and with a minimum fuel consumption and sending the signal to the load-sensing controlling device and a governor driving device (1a) for the engine.

摘要： In a speed change gear wherein sun gears, carriers and ring gears of a plurality of epicyclic gear devices are selectively fixed by respective clutches to perform switching between the forward and rearward movements and a gear change, a brake (29) is connected to the output shaft (21) of this speed change gear, whereby energy absorptions of the clutches are shared and the oil pressure of the brake (29) is controlled in accordance with the rotary speed of the output shaft (21), so that the respective clutches can be rendered compact in size. Furthermore, supply of lubricant oil is decreased when the brake (29) is released, whereby the stirring resistance of the oil is low, so that transmission efficiency is satisfactory.

摘要： A device for and method of molding for an injection molding machine, by which fluctuation in weight of an injection-molded resin product is reduced to stabilize its quality. For satisfying the purpose, a screw (61) of an injection unit (30) is moved forward to start injection of molten resin when the upper metallic mold (15) reaches a specified position, decelerated to a specified speed when advanced to a fixed position, and stopped when it reaches a predetermined stop position; and molten resin is reduced in injection flow quantity and pressurized until the gate (71) is closed.

摘要： A system for measuring an excavation position for measuring a position of an underground excavator with high accuracy by advantageously utilizing fluctuation errors which are difficult to be removed. The system comprises: a plurality of magnetic field generating devices (2) provided at known positions outside the underground excavator; a magnetic field detecting device (3) provided in the underground excavator; and a microcomputer (4) connected to the above-described devices (2, 3). The microcomputer (4) drives the above-described devices (2, 3) on the basis of an allowable error in displacement, which is specified and input to the microcomputer (4) by an operator and outputs an excavation position of the underground excavator (1) within a scope of the aforesaid allowable error. As for the aforesaid allowable error to be specified and input, a magnetic field generating device previously selected by the operator or an allowable error previously selected by the operator will serve the purpose.
