摘要： Improvement of read/write access performance with respect to a disk is proposed. A controller manages a first volume format LDEV, in which each distributed user data area and each distributed information area among a plurality of the distributed user data areas for storing a data part and a plurality of the distributed control information area for storing a control information part, are targets that capacity is changed. The controller also manages a second format LDEV, which include a plurality of groups each of which is formed from one distributed user data area and one distributed control information area, and in which each group is a unit that capacity is expanded in a real storage area. The controller converts a data address of the data part belonging to the first volume format LDEV into a data address of a data part of the second volume format LDEV in order to execute input/output processing with respect to the data part, when received an request for access to the data part belonging to the first volume format LDEV.

摘要： A plurality of modules (1) and (2) comprise a plurality of virtual volumes with which the same volume identification number is associated. A module (2), which receives a write request from a computer, searches for an unallocated real area from among a plurality of real areas in the module (2) rather than from among a plurality of real areas in the other module (1) if a real area has not been allocated to a write-targeted virtual area in accordance with the write request. The module (2) allocates the real area retrieved from the module (2) to the write-targeted virtual area, and writes data according to the write request to this real area.

摘要： In a data processing system in which a host processing apparatus and a storage subsystem are connected via a channel interface, the present invention makes it possible to expand the number of logical device addresses in excess of the device address limitations of the channel interface, and also enhances the performance of parallel access processing for the same logical device. When an access request is generated for a logical device, the host processing apparatus stores the logical device address to be accessed in a prefix command of a channel command word (CCW) for the access request, sets this CCW in a device information block of a frame which complies with the channel interface, sets a parallel access identifier for identifying a plurality of accesses for the same device in a device address of this frame, and then sends this frame to the storage subsystem.

摘要： A fuel supply apparatus is provided which works to supply fuel such as a dimethly ether used as an alternative to a typical fuel for an internal combustion engine. The fuel supply apparatus includes a high-pressure pump working to feed the to injectors from a fuel tank through a common rail, a fuel return line, and a compressor working to add to a back pressure higher than a vapor pressure of the fuel to the return line. The addition of the back pressure higher than the vapor pressure of the fuel facilitates liquidizing of the fuel. This results in a decrease in leakage of the fuel, which improves the efficiency of burning of the fuel and ensures the startability and drivability of the engine.

摘要： In control method and apparatus for data transfer in an external storage subsystem, a disk unit and a control unit interposed between a host channel and a processing unit are provided and data in a variable record length supplied from the host is converted to data in a fixed record length to write it in the disk unit. Final format writing end position information for a logical track and an erase flag indicating whether the erasing is required or not are stored at a portion of a logical track control table which controls a cache memory, for each logical track. In the format writing on the cache memory, the final format writing end position information and the erase flag are updated, and when the data is written into the disk unit from the cache memory by logical track unit, the erase flag is referred and the erasing is performed if it is required. Thus, the area of erasing and the number of times of execution are minimized and the throughput of the data transfer between the processing unit and the rotating storage device is improved.

摘要： The invention provides an encoder for subjecting an input signal to the orthogonal transform for band compression and encoding. The encoder has a sample and hold circuit which samples the input signal at a sampling frequency three times that of the input signal, and an orthogonal transform unit which subjects the sampled signal to the orthogonal transform using as a coefficient an orthogonal matrix function of the order of 3n (where n is an integer of 2 or more) having as a minor matrix an orthogonal matrix of the order of 3: ##EQU1## having given numbers a, b and c as matrix elements. By maintaining the sampling frequency low, the frequency components of the input signal may be concentrated in a small number of transform outputs without causing an increase in the amount of data to be processed, without using a multiplier and without requiring an increase in the processing speed. The input signal is thus effectively band compressed and encoded.
摘要翻译：本发明提供一种用于对输入信号进行正交变换以进行频带压缩和编码的编码器。编码器具有采样保持电路，其采样频率为输入信号三倍的采样频率，以及正交变换单元，其使采样信号进行正交变换，作为系数的顺序正交矩阵函数具有作为次要矩阵的3n（其中n是2或更大的整数）具有给定数量a，b和c作为矩阵元素的3：3的正交矩阵。通过保持采样频率较低，输入信号的频率分量可以集中在少量的变换输出中，而不会导致要处理的数据量的增加，而不需要使用乘法器，而不需要增加处理速度。因此，输入信号被有效地进行频带压缩和编码。
