An area boundary between a system common area and a job private area is set at any page boundary independently from a segment boundary, and for the segment (boundary segment) containing the area boundary, a page table is prepared for each virtual address space. Thus, virtual pages which are not used as the system common area in the bondary segment can be used by jobs as job private areas.The real page is fixedly allocated to the virtual page belonging to the system common area in the boundary segment. Thus, it is not necessary to simultaneously update page tables for the system common area. Those virtual pages may be subjects of dynamic allocation of the virtual storage.

In an organic EL panel inspection method, to determine whether an organic EL panel is good or bad, a plurality of voltages having different values are sequentially applied to the organic EL panel, thereby measuring the respective currents. According to the currents, the following three criteria are checked: criterion (1), whether or not a spike current is present in the measured currents, criterion (2), between when the plurality of voltages are sequentially applied from one direction to the other direction of the voltage and when the plurality of voltages are sequentially applied from the other direction to the one direction, whether or not currents having different current densities occur at the same voltage, and criterion (3), the absolute value of the current density of current flowing when a predetermined voltage in the reverse direction is applied to the organic EL panel.

The present invention aims to provide a fluorine-containing polymer powder that is environmentally less harmful and forms a sufficiently smooth film without impairing the properties of the fluorine-containing polymers. The present invention relates to a fluorine-containing polymer powder including a fluorine-containing polymer prepared by suspension polymerization, which contains less than 0.1 ppm of a fluorine-containing surfactant and has an average particle size of not less than 1 μm and less than 100 μm and a bulk density of 0.90 to 1.50 g/cm3.

The present invention provides a sealing member for fuel which includes a fluororubber base and a sliding-treated layer coating the surface of the base. The sliding-treated layer includes a matrix made from a fluororubber, a sliding thin film formed in the surface portion of the matrix from a molten first particulate solid lubricant, and a second particulate solid lubricant dispersed in the matrix and the sliding thin film without being melted.

A job scheduling analysis method and system are disclosed in which a job schedule is analyzed by use of historical job execution data in a computer system in which a plurality of jobs are executed in parallel. Historical execution data of a plurality of jobs and the file names of files accessed by the jobs are collected. The maximum multiplicity of jobs capable of operating in parallel on the computer system is inputted. When the file name of a file accessed by one job and the file name of a file accessed by another other job coincide with each other, an execution start condition of the plurality of jobs are determined to execute the one job and the other job at the earliest instants within the maximum job multiplicity so that the sequence of execution of processings by the one job and the other job is maintained and the execution time of the one job and the execution time of said other job do not overlap each other. Thereby, it is possible to simulate the influence of a change in system construction and to search for an effective batch processing with a reduced number of idle spaces.

In a highspeed and large-capacity data transfer operation effected between an extended storage unit and an input/output unit, such a data transfer system is provided, capable of preventing a performance deterioration caused by a lack of main storage capacity with employing a buffer having a large memory capacity, and deterioration of a transfer throughput caused by an overhead of an input/output operation due to a use of a buffer having a small memory capacity. There are provided a CCW for directly designating the extended storage unit as an object of a data transfer operation, and a signal line for initiating from a channel the data transfer operation between HSA-extended storage unit. Furthermore, buffers having the planes and with a small memory capacity are prepared on the HSA. The data transfer operation is carried out between the channel and the buffer with one plane, and the data transfer operation is performed between the extended storage unit and the buffer having the other plane in parallel with the first-mentioned data transfer operation. After the data transfer operations have been accomplished, a data transfer operation for the next block is executed by substituting one plane with the other plane.

The attachment has a rotatable spindle and the horizontal boring machine has a headstock rotatably mounting an axially reciprocable headstock spindle. A dog clutch includes a first clutch member rotatable with the attachment spindle and a second clutch member rotatable with the headstock spindle. The attachment is arranged to be bolted to the headstock with the clutch members in axial alignment. Rotation of the headstock spindle is halted in a predetermined angular position, and the headstock spindle is advanced toward the attachment. A releasable member is operable to retain the first clutch member in an angular position in which its teeth are in correct meshing alignment with the teeth of the second clutch member for smooth interengagement of the clutch members responsive to the advance of the headstock spindle. An operating member is engaged by the attachment as it is bolted to the headstock and operates a control switch which initiates operation of electric and hydraulic control elements to disengage the releasable member from the first clutch member to provide for rotation thereof. The electrical and hydraulic control elements include an operator fixed on the headstock spindle and engageable with a microswitch operator as the headstock spindle is advanced, so that, in effect, as the attachment is bolted to the headstock of the horizontal boring machine, the dog clutch is automatically engaged.

An amino group-containing metal compound such as a coupling agent having an amino group is dispersed in a fluoroelastomer coating composition comprising a fluoroelastomer and a polyol curing agent which are dissolved or dispersed in a liquid medium. The resulting fluoroelastomer coating composition can form an elastomer coating layer directly on a metal surface using no primer, and improve antifreeze resistance and deterioration of the coating film after compression at high temperatures for a long time.
