A common-mode choking coil comprises a closed magnetic path core which is formed, for example, by combining two U-shaped cores. Two coils wound in opposite respective directions are mounted on two legs of the closed magnetic path core. These coils are formed by single-layer winding. That is a conductor wire is wound in only one layer, for example, around a bobbin. Then, the bobbins whereon the conductor wire is wound are mounted on the two legs of the closed magnetic path core. For the conductor wire used for the coil, a material having a spring property may be used. Utilizing this spring property of the coil, the closed magnetic path core can be held together by the coil, whereby the two U-shaped cores can be combined. Also, the two coils are identified by colors according to the winding direction of the respective conductor wires.

A lead terminal-drawing out construction in a three-terminal capacitor wherein a dielectric substrate is provided with electrodes on both main surfaces thereof, two pieces of lead terminal extending from one of the electrodes, and one piece of lead terminal extending from another one of the electrodes. A lead terminal connected to one electrode is bent toward a lead terminal connected to other electrode whereby three pieces of lead terminal are arranged in almost the same plane. The bent portion of the lead terminal is formed by a first bent portion bent toward an opposite lead terminal and a second bent portion so as to be parallel to an opposite lead terminal, the first bent portion being once bent in an outwardly projecting direction relative to the dielectric substrate to increase a bending angle of the first bent portion of the lead terminal preventing the inclination of the capacitor when the three-terminal capacitor is automatically inserted into a printed board thus preventing breakage of the dielectric substrate.

A microwave oven is provided with a gas sensor and a heat-sensitive element (i.e. thermistor) within a passageway for outgoing air from the heating chamber. A microcomputer generates a heating stop instruction for a microwave source in response to output signals from the heat-sensitive element and the gas sensor and also in accordance with a stored program in the microcomputer. Based upon the variations with time in the output signal from the gas sensor, the microcomputer decides what kind of foodstuff is being heated and establishes a final level for the gas sensor at the end of microwave heating and a final level for the heat-sensitive element at the end of grill heating. A heating end instruction is issued when both the gas sensor and the heat-sensitive element reach their intended final levels. Furthermore, a compensation value (U) is selected based on the rate of variations in the output from the heat-sensitive element. After the microwave heating has been completed, grill heating is performed for a length of time which is determined by the compensation value (U).

A microwave oven includes a magnetron, a blower fan system, and a gas sensor for detecting an exhaustion gas concentration developed from an oven cavity. When the exhaustion gas concentration exceeds a preselected value while an actual cooking operation is conducted, the gas sensor develops a first detection output to complete the actual cooking operation. While the actual cooking operation is not conducted, the gas sensor functions as a gas leak alarm sensor. When an ambience gas concentration shows an abnormal value, the gas sensor develops a second detection output to announce a dangerous gas leakage. While the actual cooking operation is not conducted, the blower fan system is intermittently energized to introduce the ambience air toward the gas sensor for monitoring purposes.

Errors of a measuring system are corrected by acquiring the phases of transmission tracking errors. A network analyzer includes a measuring system error factor recording unit which records measuring system error factors generated independently of frequency conversion carried out by a DUT, and an error factor acquiring unit which measures first coefficients and second coefficients of a correction mixer where a signal output from a terminal is a sum of a product of a signal input to the terminal and the first coefficient, and a product of a signal input to the other terminal and the second coefficient, and the ratio of magnitudes of the second coefficients is constant, and acquires the transmission tracking errors caused by the frequency conversion based on the measuring system error factors recorded in the measuring system error factor recording unit, the first coefficients, and the second coefficients.
