Abstract: A gas compressor can efficiently reduce an oscillation (damping) generated in a housing even if the oscillation generated in a cylinder is directly propagated to the housing during operating. Each of a plurality of ribs extends from a respective one of the fitting units to the vicinity of a position where an outer surface of a rear side block of a compressing mechanism unit received in the housing is fitted (pressingly fitted) to an inner surface of the housing. The ribs are integral formed on the outer surface of the housing.

Abstract: In a car development system, a control specification development computer transmits Excel-format matching data of a car manufacturer to an XML database computer of an ECU supplier. The XML database computer converts the Excel-format data to XML-format data, and stores the data into an XML database. A software development computer of the ECU supplier requests text-format matching data, and the XML database computer extracts the matching data from the XML database, converts the data to text-format data and then transmits the data to the software development computer. A matching computer of the car manufacturer can likewise store ASAP2-format data into the XML database computer or extract the data from the XML database computer.
