A receiver is operable even if including a local oscillator generating a signal at high frequencies but not in a wide frequency range. The receiver includes: a first frequency converter for mixing a received signal with a first local oscillation signal to convert the received signal into respective signals of plural first intermediate frequencies corresponding to a frequency of the received signal; and a second frequency converter for converting the signals of the first intermediate frequencies into a signal of a second intermediate frequency.

In association with a solenoidal coil 10 being energized to unlock a shift lever, a first movable core 9 and a second movable core 11 magnetically stick together so as to rotationally move in unison from an original position in which the first movable core 9 engages with the second movable core 11. Because the first movable core 9 and the second movable core 11 stick together before unlocking the shift lever, it is possible to avoid the first movable core 9 from hitting the second movable core 11 so as to eliminate an operational noise which would otherwise be produced by hitting the first movable core 9 against the second movable core 11. A lock plate 7 and a link plate 8 are rotatably provided around a rotational center 6 in relative to the solenoidal coil 10. This prevents the lock plate 7 and the link plate 8 from moving rotationally in unison with the solenoidal coil 10, thus enabling the lock plate 7 and the link plate 8 to a smooth and quick rotational movement.

A color toner which gives a suitable image gloss and has an excellent color reproducibility, which has sufficient anti-offset properties even when a release oil is not coated on a fixing roller or is coated in only a small amount, and which has excellent transfer properties, durability, and charge stability relative to humidity is disclosed. Also, an image-forming apparatus using the color toner and a toner container filled with the color toner are disclosed. The color toner comprises a continuous phase of a resin containing a urea-modified polyester resin; and a modified resin dispersed in the continuous phase, wherein the modified resin contains a release polymer portion containing a release polymer; and a modified portion containing a plurality of vinyl monomer units, the modified portion having an average ester group concentration of 8% by weight to 30% by weight.

An electronic tuner has an input terminal, a mixer receiving the signal fed into the input terminal, a matching circuit connected to an output of the mixer, a band-pass filter connected to an output of this matching circuit, an intermediate-frequency (IF) amplifier connected to an output of the band-pass filter, and an output terminal receiving output of the IF amplifier. These circuits are composed of balanced circuits and connected by balanced lines. The mixer has a high output impedance. For the matching circuit, the impedance of the matching circuit at the band-pass filter side is equal to the impedance of the band-pass filter at the matching circuit side. This structure can realize an electronic tuner having low power consumption.
