An image forming apparatus including an image forming portion that forms an image on a surface of a sheet, a feeding device that feeds the sheet in a sheet feeding direction, a sheet receiving portion, and an engagement portion selectively moves between a first position and a second position. When the engagement portion is in the first position, the engagement portion engages the leading end of the sheet. When the engagement portion is in the second position, the engagement portion does not engage the sheet. When the engagement portion is in the first position, the engagement portion engages a leading end of the sheet before a trailing end of the sheet passes the feeding device. The sheet receiving portion receives the sheet after the engagement portion engages the leading end of the sheet.

A microphone apparatus for processing and outputting an output signal of a microphone array including at least nine microphones includes a directivity function processing circuit that converts the output signal of the microphone array into a unidirectional signal and that outputs the unidirectional signal. The directivity function processing circuit expands a directivity function whose variable is an incident angle of an acoustic wave into a Fourier series up to at least third order. The variable in the expanded expression is produced from output signals of the microphones forming the microphone array.

The object of the present invention is to efficiently dissipate heat from the upper and lower main surfaces of a semiconductor device carrying a semiconductor element. A semiconductor device (1) is provided with an insulating substrate (10A), an insulating substrate (10B) provided so as to face the insulating substrate (10A), and a semiconductor element (20) disposed between the insulating substrate (10A) and the insulating substrate (10B) and having a collector electrode and an emitter electrode provided on the side opposite to that of the collector electrode. The collector electrode is electrically connected to a metal foil (10ac) provided on the insulating substrate (10A), and the emitter electrode is electrically connected to the metal foil (10bc) provided on the insulating substrate (10B). As a result, heat generated by the semiconductor element (20) is efficiently dissipated from the upper and lower main surfaces of the semiconductor device (1).
摘要:
A DMA controller controls DMA transfer in an information processing system. Input and output devices are a transfer source or a transfer destination in DMA transfer and request DMA transfer. A DMAC activating unit is provided with an event monitoring unit and an event register. The event register registers an event subject to monitoring. The event monitoring unit detects an event generated in the input and output devices and determines whether the detected event matches an event registered in the event register. If it is determined that the events match, the event monitoring unit activates the DMA controller.
