In a conventional semiconductor device, protection of a to-be-protected element from a surge voltage is difficult because the to-be-protected element is turned on before a protection element due to variations in manufacturing conditions. In a semiconductor device of the present invention, a protection element and a MOS transistor have part of their structures formed under common conditions. N type diffusion layers of the protection element and the MOS transistor are formed in the same process, while the N type diffusion layer of the protection element has a larger diffusion width than the N type diffusion layer of the MOS transistor. With this structure, when a surge voltage is applied to an output terminal, the protection element is turned on before the MOS transistor, and thereby the MOS transistor is protected from an avalanche current.

An X-ray imaging apparatus is provided with a multi X-ray source and a collimator in which a plurality of slits for X-rays to pass through are two-dimensionally formed, the size and position of the slits being adjustable. A control unit, as a first control mode, controls the size and position of the slits to move an examination region in parallel, when an X-ray source is changed to a different X-ray source, such that the examination directions are parallel before and after the change. Also, the control unit, as a second control mode, controls the size and position of the slits to rotate the examination direction, when an X-ray source is changed to a different X-ray source, such that the center of the examination regions is the same before and after the change.

A purpose of the invention is to provide a piezoelectric speaker that can serve as an antenna and can be used for frequencies in the MHz band, thereby it is possible to suppress enlarging of the size due to use of the piezoelectric speaker also as the antenna to a minimum level. The antenna (4) is provided on a frame (2a) that is a peripheral edge portion of the diaphragm (2). With this configuration, enlarging of the size can be suppressed to a minimum level while using the piezoelectric speaker also as the antenna, and it is possible to achieve space saving in a miniature electronic apparatus such as a mobile phone or the like when the piezoelectric speaker is adopted to the miniature electronic apparatus. In addition, the antenna (4) is a loop antenna formed in a loop shape. With this configuration, the piezoelectric speaker can be used for frequencies in the MHz band, which is used in, for example, a noncontact IC card technology. Further, a magnetic material sheet (5) is provided on the other face of the frame (2a) so as to oppose to the antenna (4). With this configuration, it is possible to suppress reduction of the reception sensitivity at a time when a metallic material is placed in the vicinity of the antenna (4).
