摘要： An air/fuel ratio control system is designed for detecting small deceleration and subsequently detecting small magnitude acceleration. When small magnitude acceleration is detected, a LAMBDA control correction value which is utilized for deriving fuel injection amount, is fixed at a predetermined value for a predetermined period. The air/fuel ratio utilized during the aforementioned period is set at a value greater than the instantaneous value at a timing at which a demand for small magnitude acceleration is detected.

摘要： An embodiment of this invention divides a cache memory of a storage system into a plurality of partitions and information in one or more of the partitions is composed of data different from user data and including control information. The storage system dynamically swaps data between an LU storing control information and a cache partition. Through this configuration, in a storage system having an upper limit in the capacity of the cache memory, a large amount of control information can be used while access performance to control information is kept.

摘要： A spark ignition control system distinguishes engine operating condition between low engine load range where acceleration shock tends to be created and high engine load range where acceleration shock to be created is small and better acceleration characteristics is required. The spark ignition timing control system performs spark advance retarding control while the engine is in the low engine load range and in response to acceleration demand. On the other hand, the spark advance retarding control is disabled in the high engine load range.

摘要： To extend endurance and reduce bit cost, a method and a storage apparatus are provided, which storage apparatus includes a controller and a semiconductor storage media that includes a first storage device and a second storage device having an upper limit of an erase count of data smaller than the first storage device. Area conversion information includes correspondence of a first address to be specified as a data storage destination and a second address of an area in which data is to be stored. A rewrite frequency of stored data is recorded for each area. The controller selects an area corresponding to the first address, determines whether or not the rewrite frequency of the selected area is equal to or larger than a first threshold value, when the rewrite frequency is equal to or larger than the threshold value, selects an area to be provided by the first storage device, and when the rewrite frequency is smaller than the threshold value, selects an area to be provided by the second storage device and maps the address of the selected area to the first address.

摘要： A diagnostic system for detecting a freezing condition of an intake pressure sensor for an engine includes a control unit for checking engine operating parameters after a turn-on of an ignition switch to determining whether the engine is a predetermined state permitting a freeze diagnosis, and for performing the freeze diagnosis only when the engine is in the predetermined state. The control unit monitors a decrease of the intake pressure sensed by the intake pressure sensor as the engine speed increases from a start, and judges a freezing condition to exist if the intake pressure does not become sufficiently low even after the engine speed becomes higher than a predetermined speed level.

摘要： When a snapshot virtual volume is provided to the host as an OS image of a virtual machine in a system where a single V-VOL is used by a single VM and all the VMs are started concurrently, burdensome Copy-on-Write (CoW) accesses placing heavy I/O loads on the storage occur in concentrated manner, and the starting time is elongated. The present invention solves the problem by measuring the I/O pattern (number of IO per unit time for reading/writing) in page units during starting of the system prior to having the VMs started concurrently, and based on the measurement results, performs saving and copying of the target pages of the write access to a snapshot pool prior to starting the VM. This preliminary saving enables to reduce the CoW accesses having a high access load, and to enable reduction of the VM starting time and efficient use of the pool capacity.
