Title: Paper sheet feeder
Inventor: KURIHARA KAZUYOSHI
IPC: B41J13/02
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To provide a paper sheet feeder for feeding paper sheets at the optimum conditions through selection regarding the drive condition using both sides of its paired feed rollers or either side of them. SOLUTION: A paper sheet feeder involves a drive selector means 25 for selectively driving both or either side of feed rollers 2 facing each other to hold a paper sheet feed path therebetween. The selector means 25 selects the both-side drive mode in which both sides of the paired rollers 2 are driven to produce larger feed force, or the one-side drive mode in which either side of the paired rollers 2 is driven to produce accurate feed. That control enables the feed of paper sheets at the optimum conditions.

Filed: 1988-02-12
Abstract: PURPOSE:To simplify the constitution of the title circuit and to economize the circuit by synthesizing a time point to go over a reference potential, which is lower than the maximum value of an input alternating signal, and a time point to go under the reference potential, which is higher than the minimum value of the input alternating signal, and outputting a timing signal to have a frequency, which is two-fold of the input alternating signal. CONSTITUTION:A reference potential generating circuit 100 generates a first reference potential VS1, which is determined to be lower than the maximum value of an input alternating signal (a), and a second reference potential VS2, which is determined to be higher than the minimum value of the signal (a). A first comparing circuit 200 compares the signal (a) and the potential VS1 and extracts the time point in which the signal (a) goes over the potential VS1. A second comparing circuit 300 samely extracts the time point in which the signal (a) goes under the potential VS2. A synthesizing circuit 400 synthesizes the respective time points to be extracted by the circuits 200 and 300 and outputs a timing signal (d) to have the frequency, which is two-fold of the signal (a).

Title: Hollow yarn type module
Inventor: KIKUCHI TOSHIAKI
IPC: B01D63/02
Filed: 1985-02-21
Abstract: PURPOSE:To make it possible to simply and efficiently remove a contaminant such as colloid, by embedding air sending pipes opened at both ends in hollow yarn bundles in a dispersed state so as to pierce through the lower adhered and fixed part of a hollow yarn type module. CONSTITUTION:Hollow yarn bundles comprising hollow yarns 2 each opened at the upper end thereof and closed at the lower end thereof are received in a housing 1 and a large number of air sending pipes 5 longer than a lower adhered and fixed part 3 and opened at both ends thereof are embedded in the hollow yarn bundles in a dispersed state so as to pierce through the lower adhered and fixed part 3. When the filtering efficiency of each hollow yarn is lowered by the adhesion of colloid to the outer wall of the hollow yarn during the filtering of raw water, the supply of raw water is stopped and gas or a gas-containing liquid is sent into the hollow yarns through the air sending pipes 5 and a contaminant such as colloid is released from the wall of each hollow yarn by sent-in gas to restore the activity of the hollow yarn. Because hollow yarns hold sufficient intervals by the isolation pipes 4 in an upper adhered and fixed part 3, the sent-in gas uniformly rises through the hollow yarn bundles to enhance removal capacity.
