Title: Both right and left bending type bender
Inventor: IWAMOTO SHINICHI
IPC: B21D7/024
Filed: 1981-05-22
Abstract: PURPOSE:To freely change a bending direction as necessary by use of one bender, by selectively operating 2 bending work parts, in a both right and left bending type bender. CONSTITUTION:Bending work of a rod-like material (a) is preformed by use of a working part M. Subsequently, it is shifted to the next bending, and in case when the bending direction is changed to the right from the left, and vice versa, a holding frame body 7 is rotated by 180 deg. by operating a rotation driving machine. In case of this inversion, since the rod-like material (a) gets in the way of rotation of the holding frame body, it is made to get free to the outside of its rotating locus once by driving machines 9A, 9B, and after that, it is reversed, is returned to its original position again by the driving machines 9A, 9B, and is set to a bending mold 3 being different from that of the previous time. In this way, the rod-like material is bend-worked in order, linearly feeding it by a feed machanism.

Filed: 1980-06-12
Abstract: PURPOSE:To prevent the delay of a computer response when a load on it is high, by omitting a process to be executed accompanied by a change in state until a prescribed time passes when a digital signal from a predetermined specific equipment  changes in state. CONSTITUTION:In a receiving variable power system, for example, cause-side changes in state of breaks of a receiving breaker 21 and a transformer secondary breaker 22, and the operation of a transformer rate differential relay 24 cause result- side changes in state of breaks of feeder breakers 23-1-23-7.

When a state change bit detected by a computer is found to be at the cause side from the table, the result- side state change bit is not processed at all for a constant period and only the result-side state-change bit in the pattern C is reset. If the bit is not the state change processing interruption bit No., normal processing performed.
