Title: Switched capacitor sample-and-hold delay circuit
Inventor: SHINAGAWA NORIAKI
IPC: G11C27/02
Filed: 1992-04-07
Abstract: PURPOSE:To realize a long time delay and to reduce the scale of a circuit and power consumption by doubling as much as conventional delay amt. in a sample-and-hold delay circuit. CONSTITUTION:At the point of time of that a clock phi1 is turned on, the charge of a second capacitor 5 is discharged to a third capacitor 9 and becomes zero and the voltage Vi-Vo of a difference between an input voltage Vi applied to an input terminal 1 and an output voltage Vo is charged in a first capacitor 4. When the clock phi2 is turned on, the first and the second capacitors 4, 5 are connected directly and the charge of + or -C(Vi-Vo) is charged in them respectively. Then, when the clock phi1 is turned on again, the charge of the second capacitor 5 is discharged to the third capacitor 9 and the input voltage before 1 sample period is outputted to the output terminal 11. Thus, the 1 sample period delay double as much as conventional one is realized.

Filed: 1986-04-14
Abstract: PURPOSE:To automatically indicate the line on the way of typing the fair copy of a manuscript, by mounting a moving mechanism moving the index made freely movable in the line arranging direction of the manuscript placed on a stand by the same distance as the line itch of the manuscript. CONSTITUTION:At first, an index mount part 14 is moved upwardly by a hand to set an index 15 to the position indicating the uppermost line of a manuscript 17. When a stepping switch 16 is stepped instantaneously and lightly at each time when the terminal part of each line of the manuscript is typed while typing operation is performed, a motor 21 is rotated to rotate a pulley 29 and the index mount part 14 moves to the lower side.
