Inventor: OGI TAKEHIKO
IPC: B21B33/00
Filed: 1978-07-28
Abstract: PURPOSE:To develop the overload preventing device of high durability and reliability by interposing the shearing mechanism part which is broken by torsional shearing to the intermediate shaft of the rolling mill driving system. CONSTITUTION:A shearing mechanism part 1 is provided to the intermediate shaft of the rolling mill driving system. This comprises securing flanges 4 integrally to both ends of a circular cylinder 3 provided with a notch 2 directed to the circumferential direction and providing reamer holes 5 in the circumferential direction at the specified spacing. The flange 4 on the one side is mounted to the flange 7 integral with the intermediate shaft 6 by means of bolts 6.

Title: Complementary mos integrated circuit
Inventor: TAKEGAWA TOUJIROU
IPC: H03K19/0948
Filed: 1983-05-25
Abstract: PURPOSE:To hold stably a signal on a bus line and reduce the power consumption by connecting a storage circuit to each data bus line and flowing a current only when the potential of the bus line is changed. CONSTITUTION:When the outputs of output driving circuits 29 and 31 are on a high level, MOS transistors TRs N1 and P2 of a storage circuit 41 are made conductive, and MOS TRs N2 and P1 are made non-conductive. Even if output driving circuits 29 and 31 are made high-impedance, the potential of a data bus line B21 is held because it is raised through the TR P2 by a power source VD. Meanwhile, when the outputs of output driving circuits 29 and 31 are on a low level, TRs P1 and N2 are made conductive, and TRs N1 and P2 are made non- conductive. Since the TR P2 is made non-conductive, the data bus line B21 is held on a low level. Thus, since the circuit consisting of TRs P1, P2, N1, and N2 performs the storage operation, input driving circuts 23 and 25 do not require FF circuits, and the power consumption is reduced.
