A semiconductor device includes a converter that converts an acoustic pressure into an electrical signal and an amplifier element that includes an amplifier circuit that amplifies the electrical signal outputted from the converter. The converter includes a pedestal including a cavity formed from an upper face to a lower face thereof, and a vibration film located so as to cover an opening of the cavity on the side of the upper face. The vibration film vibrates in accordance with the acoustic pressure to thereby convert the acoustic pressure into an electrical signal. The amplifier element is located under the converter so as to cover the cavity.

A sheet processing apparatus includes a conveying roller that conveys a sheet, a processing tray on which the sheet from the conveying roller is loaded, a reference stopper provided at one end of the processing tray, a return paddle having an elastic piece for transferring the sheet from the conveying roller to the reference member, and a roller arm that moves the return paddle in the sheet thickness direction at a predetermined moving rate according to the number of sheets loaded on the processing tray. The moving rate of the roller arm is reduced as the number of sheets loaded on the processing tray is increased. With this configuration, aligning property of even a wavy sheet can be suppressed from being deteriorated at sheet loading.

Provided is a computer system including a first server and a storage system. In the first server, a first virtual server and a second virtual server are operated. Upon reception of a request to boot the first virtual server, the second virtual server judges whether system software of the first virtual server, which is requested to be booted, matches system software of the first server in which the first virtual server is operated. In the case where the system software of the first virtual server and the system software of the first server do not match, the second virtual server updates the system software of the first virtual server before booting the first virtual server.
