摘要： An automatic time constant adjustment circuit has an error detection circuit and a variable time constant circuit. The error detection circuit detects, based on the resistance of an error reference resistor and the capacitance of an error reference capacitor provided therein, a resistance/capacitance error resulting from a variation attributable to an IC process, and then outputs a control signal corresponding to the resistance/capacitance error. The variable time constant circuit includes a resistance portion, a capacitance portion, and a switch portion. The resistance portion is build with one or more resistors. The capacitance portion is build with one or more capacitors. The switch portion sets the time constant of the variable time constant circuit according to the resistance/capacitance error by connecting together one of the resistors of the resistor portion and one of the capacitors of the capacitor portion according to the control signal.

摘要： A sealing device to be applied between a piston and a cylinder of a disk brake on an automobile. The sealing device comprises an annular seal groove provided in the inner surface of the cylinder and a seal ring inserted in the seal groove, the seal groove having a beveled wall between its front and bottom walls, the seal ring having a beveled surface provided between its front and outer surfaces and engageable with the beveled wall of the seal groove, the seal ring being compressed into the seal groove by the piston with a space between the front surface of the seal ring and the front wall of the seal groove. When the piston of the disk brake is activated hydraulically, the seal ring is elastically deformed with the movement of the piston to build up elastic energy. When the piston is set free from the hydraulic pressure, the piston returns easily to its original position by means of the elastic energy built up in the seal ring.
