Abstract: A pressure detecting device that detects the combustion pressure in an internal combustion engine includes: a piezoelectric element that outputs a charge signal corresponding to the pressure in a combustion chamber; and a mounting board on which are mounted an integrating circuit that integrates the charge signal outputted by the piezoelectric element and an amplifier circuit that amplifies a voltage signal obtained by integration. On the mounting board are provided: a power receiving terminal that receives a power-supply voltage from a controller; an output terminal that outputs an output signal after amplification to the controller; and a grounding terminal for making the ground of the controller and the mounting board common. Furthermore, in the mounting board, the grounding terminal and grounding ends of the integrating circuit and the amplifier circuit are connected by way of grounding ferrite beads.

Abstract: An in-cylinder pressure detecting apparatus for detecting a pressure in a combustion chamber of an internal combustion engine is provided. The in-cylinder pressure detecting apparatus includes a pressure detecting element mounted on a fuel injection device which injects fuel into the combustion chamber; and an amplifying circuit unit having an amplifying circuit which amplifies a signal output from the pressure detecting element and outputs a pressure detection signal. An in-cylinder pressure detecting unit including the pressure detecting element, the amplifying circuit unit, and a connecting member connecting the pressure detecting element with the amplifying circuit unit, is integrated with the fuel injection device, and an external surface of the amplifying circuit unit is shielded with metal thin film.

Abstract: After the initialization of the information processing apparatus, the MMB reads out a value in the Negotiated Link Width register and stores the value in a RAM. When receiving an interrupt from the I/O bridge, the MMB reads out a value in the Negotiated Link Width register again and compares the value with the value stored in the RAM. When both the values are different, the MMB transmits a message to a console and takes predetermined measures, such as separation of the device.

Abstract: An interface control device controls the packet-type transfer of data between one or more computers and one or more input/output devices. According to one embodiment of the present invention, when the interface control device receives the lead packet in a series of packets from an input/output device, it creates new device control data to control the transfer of the series of packets, and also determines an identification number for the particular series of packet transfers. The interface control device then sends a notification packet, containing the identification number, to the sending input/output device in response to receiving the lead packet. When the interface control device receives a packet that is a second or subsequent packet in the series of packets, it determines whether the data stored in the packet are normal by referring to the device control data corresponding to the identification number stored in the subsequent packet.
