摘要： A control apparatus for an internal combustion engine includes a turbocharger; an exhaust gas purifying catalyst which is arranged at a section downstream of a turbine in the exhaust passage; and a low pressure EGR passage which connects a section downstream of the exhaust gas purifying device in the exhaust passage and a section upstream of a compressor in the intake passage. The compressor is provided with a movable vane mechanism capable of varying throttled quantity of a flow passage of intake gas by moving diffuser vanes. The movable vane mechanism is controlled so that the throttled quantity of the flow passage is decreased when the exhaust gas is led to the compressor via the low pressure EGR passage as compared with a case when the exhaust gas is not led to the compressor.

摘要： In a CDR-mode disk storage device, an HDC translates logical block addresses, generated by a host computer when the computer accesses the disk, to physical block addresses each consisting of a zone number, a head number, a track number, and a sector number. At this time, the HDC prepares a translation table which shows physical block addresses corresponding to logical block addresses. In the translation table, serial zone numbers 0-zn are set, serial head numbers 0-hn are set for each zone number, serial track numbers 0-tn are set for each head number, and serial sector numbers 0-sn are set for each track number. On the basis of the physical block addresses, the disk storage device can access sectors corresponding to a series of logical block addresses sequentially designated, without increasing the number of occasions of zone changing.
