    摘要： A portable telephone apparatus includes a reference frequency generating section capable of suitably changing frequency accuracy of an output signal in accordance with an input control voltage, and a high-accurate reference frequency generating section having accuracy for a temperature change extremely higher than that of the reference frequency generating section and in which output frequency accuracy thereof changes only within a range of prescribed values. A determination device determines whether or not frequency accuracy of an output signal from the reference frequency generating section meets the prescribed value. A selector selects an output signal from the reference frequency generating section in a case that a determination result of the determination device meets the prescribed value, and selects an output signal from the high-accurate reference frequency generating section in a case that a determination result of the determination device does not meet the prescribed value.

    摘要： To obtain a high-quality cast product of a cylinder head, a proper directivity to the cooling process of the molten metal after a pouring process by utilizing the shape of a cylinder head is discussed. In a process where molten metal is injected to a casting mold cavity formed between upper and lower molds to fill it therewith so that the molten metal is solidified to form a cylinder head of an engine, a plurality of core protrusions corresponding to holes (plug holes and bolt holes) are formed in the upper mold, and a cooling means is attached to each of the core protrusions. With respect to cooling means attached to the plurality of core protrusions, those attached to the inner core protrusions comparatively closer to the center of the casting mold are designed so as to have a greater cooling capability than those attached to the outer core protrusions; therefore, with respect to the center portion and the outer portion of the casting mold cavity.

    摘要： A plasma processing apparatus comprising a plurality of plasma processing units is provided. Each of the plasma processing units has a matching circuit connected between a radiofrequency generator and a plasma excitation electrode. Among these plasma processing units, a variation between the maximum and minimum values of input-terminal-side AC resistances RA of the matching circuits defined by =(RAmax−RAmin)/(RAmax+RAmin) is adjusted to be less than 0.5. A variation between the maximum and minimum values of output-terminal-side AC resistances RB of the matching circuits defined by =(RBmax−RBmin)/(RBmax+RBmin) is also adjusted to be less than 0.5. The plasma processing units can be adjusted to achieve substantially uniform plasma results in a shorter period of time.
