In a semiconductor strain detector, the temperature characteristic of the output of a zero-point temperature compensating circuit is added to the zero-point temperature characteristic of the output of a bridge circuit composed of strain gauges, to perform a zero-point temperature compensation of the final output. Further, two kinds of diffusion resistors having different surface impurity densities are used in each amplifying circuit to perform a sensitivity-temperature compensation in which a te…

A novel harvesting machine is usable with a novel method for transformation from an operating position to a transport position. The machine has a set of work wheels and a set of transport wheels which extend on transverse axes. The transport wheels extend substantially parallel to, and on both sides of the longitudinal axis of the body of the machine. When the work wheels are lowered the resulting raising of the body of the machine permits the transport wheels to be lowered. Subsequently, the bo…

A hydraulic actuator control circuit capable of increasing the flow rate of the working fluid supplied to hydraulic actuators when the load on the hydraulic actuators increases beyond predetermined values includes a first valve group having a plurality of pilot controlled selector valves connected, respectively, to hydraulic actuators, a second valve group having a plurality of pilot controlled selector valves connected, respectively, to lines connecting the hydraulic actuators to the pilot cont…

A biaxially stretched polyester film which satisfies the following equations (1) to (4): wherein .DELTA.P, n and .sup..alpha. MD+TD respectively respect the degree of surface orientation, the average refractive index and the sum (%) of the shrinkage in the machine and transverse directions after the film is subjected to heat treatment at 105.degree. C. for 30 minutes. The film is not easily curled even if one side thereof is treated with a solvent, and is thus suitable for use involving a step o…

A robot controller for an articulated robot, capable of controlling the articulated robot for the highly accurate high-speed movement of the work along a predetermined route. The robot controller a memory for previously storing functions for calculating position gains and speed gains for the joints of the articulated robot. A detecting operates to detect the present position and present speed of each of the joints during the operation of the articulated robot. A first calculating operation calcu…

A mower according to the invention includes a mowing group provided with a cutting bar and skids. The rear connection of each one of the skids includes connection means that allow the rear part of the skid to separate from the cutting bar in a relative movement directed backwardly, considering the direction of advance.

A shrinkable polyester film having a sufficient shrinkage, a sufficient resistance to solvent for printing ink, a shrinking property not to cause wrinkles, a warm water resistance sufficient for preventing wrinkles, slack and whitening is disclosed herein. The shrinkable polyester film of the present invention may be used as labels for various vessels such as glass bottle, heat-resistant PET bottle and non heat-resistant PET bottle.
