摘要： In an apparatus for correcting deflection produced in a construction due to the weight of the construction or movement of a movable member supported by the construction, a condition data representing the deflection associated with the moved position of the movable member is stored in a memory section of a correction controller. The movement of the movable member is detected by a position detector and a position signal is generated from the position detector. A command signal is supplied to a calculator and the position signal is received in the calculator synchronized with the command signal. The condition data is accessed by the calculator with the received position signal and is processed into a correction data. A correction data is supplied to a proportional control electromagnetic valve and a hydraulic cylinder for applying a force onto the construction is regulated by the valve to correct the deflection of the construction.

摘要： A control system for effecting ultra-precision temperature control for a controlled system having large load fluctuations or including a dead time component. A control unit (5) instructs a high-precision PID temperature controller (10) to renew and correct a control target value T.sub.0,NEW for the supply fluid temperature T.sub.0 only by a temperature difference .DELTA.T=T.sub.C -T.sub.2 between a set value T.sub.C for the return fluid temperature T.sub.2 of a heat transfer fluid and the actually controlled return fluid temperature T.sub.2. In response to the instruction, the high-precision PID temperature controller (10) controls the heating power of a heater (17) for heating control through a constant-power thyristor phase controller (16). The heater (17) heats the heat transfer fluid and sends it to a machining apparatus (1) through a closed damping tank (21). The heat transfer fluid exchanges heat with the machining apparatus (1) and is then returned to a precooling means.

摘要： An automotive vehicle has a single integral door opening on each side of the door body. The door opening is closed by a pair of front and rear doors which are slidable along the vehicle side to open and close the door opening. The rear edge of the front sliding door and the front edge of the rear sliding door directly oppose each other without a vehicle body pillar therebetween. The opposing edges of the sliding doors have seals for water-proofing. Also, the upper edges of the sliding doors sealingly contact seals mounted on vehicle side frames extending along upper edge of the door opening for water-proofing. Guide rails slidingly supporting the sliding doors are mounted on the side frames in such a manner that they serve to reinforce the side frames. Lower seals are provided between the lower edges of the front and rear doors and the lower side frames for establishing water-tight seal therebetween.

摘要： In a static pressure table device wherein an annular recess is formed in one of confronting surfaces of a stationary bed and a rotary table thereon, and static pressure oil is supplied to the recess for rotatingly support the table on the bed, a static pressure gap formed between the confronting surfaces of the bed and table is constructed to gradually or stepwisely increase toward the outer periphery of the device. As a result, the viscosity resistance of the pressure oil is decreased toward the outer periphery and heat generation is reduced in the outer peripheral region, whereby a uniform temperature distribution of the table becomes possible with resultant reduced thermal deformation of the table so that the table can be rotated at high speed.
