A rotation angle sensor comprises: a resolver stator including an excitation coil for receiving an excitation signal and a detection coil (a sine wave coil and a cosine wave coil) for outputting a detection signal; and a resolver rotor rotatably placed to face the stator. The resolver stator is formed on a stator flat plate. The resolver rotor is made of a flat-shaped rotor flat plate. The stator flat plate and the rotor flat plate are placed in parallel to face each other. The rotor flat plate is formed with a cutout.

A semiconductor device includes a plurality of sets of external drive terminals in a marginal region along one long side of a rectangular semiconductor substrate, a plurality of sets of ESD protection circuits arranged in the marginal region and coupled to corresponding sets of the drive terminals, and a plurality of output circuits coupled to corresponding sets of the drive terminals. Each set of drive terminals in a plurality of n columns along a Y direction is laid out in a staggered arrangement with drive terminals in adjacent columns shifted relative to each other. Each output circuit includes n output units associated with n drive terminals of each set and arranged in one column in an X direction. By the arrangement, the drive terminals can be arranged at a narrower pitch, and the total width for n output units can be compacted into that of one output circuit.

An image processing apparatus includes a resolution determining section that determines, for a selected combination of an input terminal and an output terminal, an input set resolution set for an input terminal to be a processing resolution, when an output set resolution of an output terminal is set to “Source”; and ignores the input set resolution set for the input terminal and determines the output set resolution set for the output terminal to be a processing resolution, when the output set resolution of the output terminal is set to other than “Source”.

An earpiece, an electronic device, and a communication device, capable of reducing the influence of leakage of sounds from a clearance between the earpiece and an ear not to need an addition of parts are provided. An earpiece (100) includes an electromechanical acoustic transducer (10) having a diaphragm and for generating a sound by vibrating the diaphragm in response to an electric signal, a case (11) on which a sound hole (12) is provided and in which the electromechanical acoustic transducer (10) is housed, and a holding member (13) for holding the electromechanical acoustic transducer (10) in the case (11). The electromechanical acoustic transducer (10) has a sound pressure-frequency characteristic that is compensated in advance such that the sound pressure-frequency characteristic is planarized in a condition that the generated sound is leaked from a user's ear (14) being covered with the case (11).

An image forming apparatus includes a developing container for containing a developer including toner and a carrier; a feeding member for feeding the developer contained in the developing container; a drive control portion, capable of selectively executing at least operations in a first mode in which the developer is fed at a first feeding speed by the feeding member to form an image and a second mode in which the developer is fed at a second feeding speed, different from the first feeding speed, by the feeding member to form an image, for controlling the feeding speed of the developer by the feeding member depending on the operation in the mode to be executed; a toner content detection sensor for detecting toner content by using magnetic permeability of the developer contained in the developing container; and a voltage control portion for controlling a control voltage to be inputted into the toner content detection sensor. When the operation in the second mode is executed after the operation in the first mode is executed, the voltage control portion controls the control voltage in the second mode on the basis of a latest output value outputted by the toner content detection sensor in a preceding first mode.
