Title: Semiconductor memory with function of detecting power failure
Inventor: NISHIMURA KOUTAROU
IPC: G06F12/16
Filed: 1978-09-13
Abstract: PURPOSE: To prevent error write operation in a data retention mode by controlling inhibition of the write operation on detecting a power voltage falling on the basis of an offset voltage of the Fermi energy level of two semiconductors.  
     CONSTITUTION: To gates of N-type MISFETs Q 2  and Q 4  differing in threshold level and forming an operational amplifier together with load MISFETs Q 1  and Q 3  of voltage detection circuit 7, power voltages divided by resistances R 1  and R 2  are applied and the operational amplifier is applied with the power voltage to develop an offset voltage corresponding to a difference in threshold voltage based upon the Fermi level of FETs Q 2  and Q 4 . When the power voltage falls to  decrease a difference between power voltage and the gate potential of FET Q 2  down to less than the offset voltage, FETs Q 2  and Q 4  turn OFF and a data retention mode is detected invert immediately control output (c) of circuit 7 through the operational amplifier under no influence of a temperatre on the basis of not the threshold voltage but the offset voltage. As a result, gate 5 opens to inhibit the chip selection of RAM1, so that error write operation will never be done in a power failure.

Title: Multi-stage cluster rolling mill
Inventor: MORIYA MUNEO
IPC: B21B29/00
Filed: 1983-06-23
Abstract: PURPOSE:To prevent generation of roll marks with a rolling mill having plural divided backup rolls by making the diameter at both ends of the divided rolls smaller than the diameter in the central part. CONSTITUTION:Backup rolls 10 which contact with a pair of intermediate rolls 3a, 3b of a rolling mill are constituted of plural divided rolls 10 and other backup rolls 11 are constituted of plural divided rolls 11a or 11b. The rolls 10a, 10b, 11b have the drum shape in which the diameter (d) at both ends is smaller than the diameter D at the center and the outside circumferential surface is gently formed. If a material 1 to be rolled is rolled with such rolling mill, the rolls 10a, 11a, 11b that contact with the rolls 3a, 3b have the drum shape and therefore the exertion of a large face pressure only on the outside circumferential surface of the rolls 3 in contact with the ends of the divided rolls as in the prior part is obviated. The generation of stripe-shaped roll marks on the outside circumferential surface of the rolls 3 is thus obviated and no roll marks are formed on the rolled material 1.

Title: Shear line
Inventor: HAYASHI SHIGEKI
IPC: B23D36/00
Filed: 1989-05-01
Abstract: PURPOSE:To set cut available speed even in a short size material easily by giving the average running speed (line speed) and the cut length of the material to numerically controlled device which moderates both of a feed-out machine and a cutting machine individually and then sets them in the same certain speed. CONSTITUTION:In case of a short size material, a shear motor is accelerated in speed over synchronous speed Vs, the equivalent of Lso-Ls that the movement quantity Ls (slash portion) of an edge is shorter than the one-turn movement quantity Lso of the edge, provided that the material moves while keeping the synchronous speed Vs during a cut period (T) as shown in Fig. (C). T = Ls/Vso holds. On the other hand, a feeder motor is decelerated in speed below the synchronous speed Vs, the equivalent of Ls-L that feed-out length or synchronous length Ls is longer than cut length (L), provided that the material is fed out at synchronous speed Vs during the cut period (T) as shown in Fig. (D). The area of the slash portion refers to feed length or feed length (L), and so line speed V = L/T holds. The speed Vs during cut thus gets higher than the line speed V.
