摘要： In a crystal-oscillator circuit having a quartz crystal unit, further stabilization of output frequency change at a time of startup of the power supply is achieved. A crystal-oscillator circuit having a quartz crystal unit includes a first variable-capacitance element, which forms an oscillation loop with the quartz crystal unit, and a temperature compensation circuit which provides a first control signal for the first variable-capacitance element to compensate for a temperature characteristic of the quartz crystal unit. In addition, the crystal-oscillator circuit includes a second variable-capacitance element group, and a time constant circuit which provides a time constant signal, which changes with a predetermined time constant, for the second variable-capacitance element group as a second control signal.

The contents of the alloy elements fall within ranges: 2.0 mass %≦Mn+Cr+Mo≦3.0 mass %, 2.3 mass %≦C+Mo+5V ≦3.7 mass %, and 2.7 mass %≦2.16 Cr+Mo+2.54V≦4.0 mass %. If a steel sample extracted from a central portion of the nitrocarburized steel free from an influence of the nitrocarburizing treatment is austenitized at 1200° C. for one hour, and cooled to a room temperature so that a cooling rate at which the steel sample passes through a temperature range between 900° C. and 300° C. is 0.5° C./second, then an area percentage of a bainite structure in steel structures is 80% or more and a Vickers hardness measured at a cross section is 260 Hv or more and 330 Hv or less. A surface hardness of a nitrocarburized layer is 650 Hv or more, a formation depth of the nitrocarburized layer is 0.3 mm or more, and a hardness of the central portion is 340 Hv or more. Thereby a crankshaft which is excellent both in the machinability and in fatigue strength, even after nitrocarburizing treatment on the surface, is provided.
