Title: Differential amplifier
Inventor: YAMAGUCHI TAKASHI
IPC: G11C11/419
Filed: 1985-10-09
Abstract: PURPOSE:To reduce power consumption by shifting a current interruption transistor in an off state based on a fine voltage difference so as to disconnect a space between a load transistor and a power source voltage after a certain period has expired since an amplifier transistor was activated. CONSTITUTION:During a period when information reading is completed after differential amplification starts, dummy bit lines D and B maintain a power source voltage VCC, and accordingly in a PMOS 16 the potential of a gate is approximately equal to a grounding potential and holds an on state. On the other hand, since a gate is connected to the bit line B through an inverter 18, a PMOS 17 raises a voltage impressed to the gate and is shifted to an on state when the voltage of the line B drops. When the difference pressure between the gate voltage and the power source voltage is smaller than a threshold, the PMOS 17 becomes an off state, and a current flowing in an NMOS 15, that is, the consumed current of the differential amplifier, is sharply decreased. When the voltage B of the gate of the NMOS 13 is smaller than a threshold, said current comes to zero.

Title: Lining of conduit pipe

IPC: B05D7/22
Filed: 1993-09-13
Abstract: PURPOSE:To ensure that a ling layer has an adequate thickness by introducing a flexible pipe into a conduit pipe and filling a gap between these pipes with a lining agent to obtain a first lining, and then squeezing the lining agent through a pig to obtain a second lining. CONSTITUTION:A conduit pipe 1 such as a gas pipe is arranged in such a manner that it passes through a culvert with a wall 2 formed around it, and in the internal space of the culvert 2, an overhead conduit pipe part 1a consisting of a conduit pipe 1 suspended across aerially is formed. In this case, the overhead conduit pipe part 1a is lined on the internal surface by first, introducing a flexible pipe 3 into the interior of the part 1a and then filling the gap between these two pipes with a lining agent 4. Thus a first inner surface lining is applied. Next, the lining agent 4 in one end of the conduit pipe 1 is sent under pressure to the other end side through a pig, while the pig is introduced through the interior of the flexible conduit pipe 3. Consequently, a second inner surface lining is applied to the inner side of the part where the first inner surface lining is applied.

Title: Paper feeder for copying machine and the like
Inventor: AKIYOSHI YUJI
IPC: B65H3/12
Filed: 1985-10-14
Abstract: PURPOSE:To make a follow-up feeding phenomenon of paper so as not to occur even in case size of the paper to be fed is small, by altering suction force of a suction box according to paper size. CONSTITUTION:In the case where size of paper 2 is small, if a paper rear end guide 12 is moved to the left as adjusted to the size of the paper 2, interlocking with this movement, a valve plate 10 also moves to the left, so that a part of a through hole 4d is opened. With this constitution, since a part of the atmosphere flows into a suction box 4a from this through hole 4d, suction force in this suction box 4a reduces up to a degree of pressure capable of conveying the small sized paper 2. And, with this reduction of the suction force, pressure to be reduced at the time ranging from that a paper detector detects the paper 2 to that a valve is fully closed also comes to be like a curve B shown in illustration, whereby it becomes less than the conveying force (B) required for conveyance, so that even if a rear end of the paper 2 passes through the rear end of the suction box 4a and thereby a clearance is produced there, follow-up feed of the next part 2 is surely preventable.
