摘要： A semiconductor device is designed in such a manner the distance from the bottom of a mesa groove to the pn junction on the lower side is greater than the extension of the depletion layer from the pn junction on the lower side when a voltage which is substantially equal to the target breakdown strength is applied. Then the part other than the corners of the mesa groove, that is, the width of the groove on the straight line part, is substantially equal to the distance from the bottom of the mesa groove to the pn junction on the lower side.

As the result, when the control valve is switched to supply the fluid discharged from a hydraulic pump into the first or the second main circuit, the fluid discharged from the hydraulic pump slowly acts on the spring chamber of the safety valve to gradually raise a set pressure, so that such disadvantages can be avoided that, during the reverse operation of the control valve, shocks occur or a high peak pressure is generated at the time of the stop of the hydraulic motor in operation.
