摘要： There is provided a parallel computer and a parallel computing method which allows high precision parallel calculation to be executed without requiring a hardware scale while maintaining high calculation speed. A system is constructed by connecting a host processor with a plurality of special purpose processors via buses. The host processor carries out the operation in a format of double-precision floating-point and the special purpose processor carries out the operation in an internal format of floating-point. The special purpose processor comprises an input data converting section for converting from the double-precision to the internal format and an output data converting section for converting from the internal format to the double-precision. Because the sign part and the exponent part can use data in common in the data before and after the conversion, only the mantissa part is converted by a specific procedure.

摘要： Matrix element calculation carried out efficiently without the overhead of communication between a host computer and processor elements even in parallel calculation utilizing a low-cost communication device and multiple processor elements having memories of a small capacity. In a method for calculating molecular orbitals, for example, all elements F(I, J) of a Fock matrix are calculated where an outermost loop is a loop associated with combinations (RT) of contracted shell R and contracted shell T which satisfy relationships R≦Nshell and T≦R. A second loop is a loop associated with contracted shell S, and a third loop is a loop associated with contracted shell U. Alternatively, the second loop is a loop associated with the contracted shell U, and the third loop is a loop associated with the contracted shell S. The value of S ranges from 1 to R, and the value of U ranges from 1 to R. Calculation of predetermined electron repulsion integrals and calculation of a predetermined part of Fock matrix elements utilizing the result of the calculation is carried out inside the third loop.

摘要： When parallel processing is executed by parallel computers composed of a host computer and a plurality of processors connected to the host computer through a common bus, there is provided a method of assigning jobs to respective processors with high efficiency. A job in which a ratio between a communication time and a calculation time is larger than a predetermined value or larger than a fraction of processors and a job in which a ratio between a communication time and a calculation time is smaller than a predetermined value or smaller than a fraction of processors can be alternately assigned to respective processors. Alternatively, jobs are assigned to respective processors in such a manner that a plurality of processors and a plurality of jobs are divided into a plurality of groups in a one-to-one relation, jobs in which sizes comprising communication time and calculation time and ratios between the communication times and the calculation times approximate to each other may belong to different job groups and the order in which the jobs in which the sizes comprising the communication time and the calculation time and the ratios between the communication times and the calculation times approximate to each other are assigned within respective job groups may differ from each other among a plurality of job groups.

摘要： This invention concerns a belt conveyor for delivering pantyhose whose panty part only has just been seamed by a panty part sewing machine to a toe part sewing machine in order for the leg part to be received smoothly. When the half made pantyhose are on their way to the toe part sewing machine with the panty part held by clipping members and the leg parts dangling from a guide pipe of the panty part sewing machine, the belt conveyor, disposed between both the paths of clipping members of the panty part sewing machine and suction members of the toe part sewing machine, correctly receives the leg parts one by one in association with a guide member disposed in contact with the belt conveyor at a little time interval. One of the leg parts, received by the belt conveyor first, is delivered, by their suction, to the suction members then coming nearby; the other is delivered in the same way a little later. The belt conveyor moves back and forth to carry the leg parts and return to the original position in such exact synchronization with the circular movement of the clipping members of the panty part sewing machine and the suction members of the toe part sewing machine that the delivering can be made without failure despite the fact that leg parts of pantyhose are so light and soft as fluttering by a slight air stream. Also, the separate sewing system, conventionally made for panty part and leg parts, can be joined together by the exact delivering of the belt conveyor, with the result that the rationalization in hosiery workshops, including the process control and labor-saving, can surely be achieved to the greatest extent.
摘要翻译：本发明涉及一种皮带输送机，用于将短裤部分刚刚被内裤缝纫机缝合到趾部缝纫机，以便使脚部顺利地接纳。当一半的连裤袜正在前进到脚趾部分缝纫机的时候，内裤部分由夹持件保持，内裤部分悬挂在内裤缝纫机的导管上，带式输送机设置在两个剪裁路径之间内裤部分缝纫机的成员和脚趾部分缝纫机的抽吸部件，以与时间间隔相邻的引导部件一起一个接一个地正确地接收腿部部件。首先由带式输送机接收的其中一个腿部件通过其抽吸被传送到吸附构件，然后到达附近; 另一个以相同的方式交付一点。带式输送机前后移动以携带腿部件并以与内裤部分缝纫机的夹持部件和脚趾部分缝纫机的抽吸部件的圆周运动完全同步地返回到原始位置，即输送罐尽管事实上连裤袜的腿部部分如此轻巧柔软，但是由于轻微的气流而飘动，所以不会发生故障。另外，通常用于内裤部分和腿部的单独的缝制系统可以通过带式输送机的精确输送而连接在一起，从而可以确定包括过程控制和省力的袜子车间的合理化最大限度地实现。
