Title: Solar-baterry paddle holding and releasing mechanism
Inventor: HONDA TOSHIO
IPC: H01L31/04
Filed: 1978-11-30
Abstract: PURPOSE: To prevent the effect of a retaining bolt on an inertial force of rotation of a solar battery paddle by holding the retaining bolt to a retaining bracket by an elastic member when the bolt is released from a separation nut.  
     CONSTITUTION: When a female screw portion 13 of a separation nut 8 which is screwed with a male-screw portion 21 of a retaining bolt 12 is released, the bolt 12 is instantly pulled out by an elastic force of a spring 23 which is embedded in a retaining bracket 11 of an outer panel 4 of a solar battery. However, the male-screw portion 21 of the bolt 12 prevents the bolt 12 from being pulled out of the bracket 11 owing to the female-screw portion 22 of the bracket 11. That is, the bolt 12 is fixed to the bracket 11. Therefore, in the case the solar-battery paddle rotates, since the bolt 12 instantly moves in the linear direction, the holding and releasing mechanism can be made small. Furthermore, the effect on the inertial force during the rotation of the solar-battery paddle can be prevented.

Abstract: PURPOSE:To improve the availability of each processor by making an arithmetic unit which inputs the comparison processing result of data groups finish the comparison of these data groups before each arithmetic unit starts the comparison of data groups and outputs these comparison processing results to the next arithmetic device. CONSTITUTION:The time t1 needed for the comparison processing of a processor P1 is equal to the time t01 needed for a processor P0 to start its comparison processing and then outputs the synthetic extraction data to the processor P1. Meanwhile the time t2 needed for the comparison processing of a processor P2 is equal to the time t12 needed for the processor P1 to start its comparison processing and then outputs the synthetic extraction data to the processor P2. Each processor inputs the synthetic extraction data received from its precedent processor right after the end of the comparison processing and at the same time performs the duplication eliminating synthetic processing to output the synthetic extraction data to the next processor or a main processor 2. Thus each processor is not required to wait for the next processing after the end of the comparison processing. As a result, the availability is improved for each processor.
