  • Patent number: 9217970
    Abstract: A heater for fixing devices includes a glass substrate, a heating element, electrode patterns connected to the heating element, a first protective layer, and a second protective layer. The glass substrate is made of an alkali-free glass. The first protective layer is formed by firing a mixture of a first glass powder and a first filler. The first glass powder contains no alkali metal oxide and has a lower softening point than the glass substrate. The first filler has a lower thermal expansion coefficient than the alkali-free glass for the glass substrate. The second protective layer is made of a material that does not contain the first filler contained in the first protective layer.
    Type: Grant

  • Publication number: 20110051015
    Abstract: A television signal receiving tuner includes a mixer circuit configured to convert a frequency signal of a reception channel regarding a digital television signal or an analog television signal into an intermediate frequency signal, a first intermediate frequency amplifying circuit connected to a rear stage of the mixer circuit, a trap circuit connected between any one of an output terminal of the mixer circuit and an input terminal of the first intermediate frequency amplifying circuit and a ground, and attenuating a frequency band, which is adjacent to the intermediate frequency signal, on a basis of an attenuation point, and a tuned circuit connected between the output terminal of the mixer circuit and the input terminal of the first intermediate frequency amplifying circuit to tune the intermediate frequency signal by employing the attenuation point or a frequency band approximating to the attenuation point as a tuning point.
