  • Patent number: 9490758
    Abstract: There is provided a power amplifier capable of readily reducing odd-order harmonic waves even in high frequencies. This power amplifier includes n current sources (where ā€œnā€ is a natural number equal to or greater than 3) that cause predetermined currents to flow; n switches that open and close current paths of the n current sources, respectively; and a signal generating section that generates n timing signals for turning on/off the n switches, respectively. In the power amplifier, the n timing signals are signals that have an identical duty ratio and that are different in phase; and the power amplifier outputs a signal amplified in power based on the currents flowing through the n current sources.

  • 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.

  • Patent number: 9002439
    Abstract: The present invention relates to a blood vessel wall analyzing apparatus provided with a structure enabling accurate measurement of plaque components in a blood vessel wall in a state that reduces the burden on a patient. In the blood vessel wall analyzing apparatus (1), measurement light is illuminated onto a measured portion within a blood vessel such as a carotid artery (C) from a light illuminating unit (30) provided outside the blood vessel, while light from the measured portion is detected in a light receiving unit (40) provided outside the blood vessel. Thus, since the status of the blood vessel wall can be analyzed without inserting an apparatus involved in measurement into the blood vessel, the burden on the patient is reduced during measurement.
