Title: Paper feeder
Inventor: SEGAWA HIROYUKI
IPC: B65H3/06
Filed: 1984-06-26
Abstract: PURPOSE:To enable the sure feed of paper, by performing control to inhibit the movement of a paper rest during the drive of a send-out roller even if the paper is below a prescribed level, so as to prevent the paper from being skewed, damaged and jammed. CONSTITUTION:A send-out roller 34 is rotated through a controller to send an uppermost sheet of paper 22 to a paper feed roller 30. When sequential feeding is performed according to a paper feed signal until the uppermost sheet of paper 22 reaches a position shown by a dotted line in the drawing, a second sheet detection switch 39 is turned on to generate a paper rest drive signal and apply it to the AND circuit of the controller. Regardless of the paper rest drive signal, no input is applied from an inverter while the paper feed signal is generated, so that no output is sent from the AND circuit. For that reason, a motor 24 for vertical movement remains at a standstill. When the generation of the paper feed signal is stopped, an output is sent from the AND circuit so that a paper rest 23 is moved up by driving the motor 24. The contact of the send-out roller 34 with each sheet of paper is thus stabilized to prevent it from being skewed.

Title: Air vent apparatus for water supply tube
Inventor: TAKEDA NOBORU
IPC: F16K24/06
Filed: 1983-07-18
Abstract: PURPOSE:To prevent backwater by communicating a back pressure in the primary side to the secondary side through a small communicating clearance at the time of water supply stoppage by a semiclosed check valve so that the back pressure in the secondary side may not become excessive by making the air vent area smaller than the diameter of the water supply tube. CONSTITUTION:In this apparatus, a union nut 2 is connected to a water supply source, and a coupler 4 is connected to a shower hose for instance. Water supply from the supply source pushes up a check valve 11 to close an air vent 6 by a vent valve 6 to supply the water flown into the secondary side of the valve body 1 to the shower hose through the coupler 4. On the other hand, when the water supply is shut off, the check valve 11 closes a water inlet by the resiliency of a coil spring 17, but its primary side 13 and secondary side 14 are communicated through a passage clearance 12. As a result, the back pressure in the primary side 13 is transmitted to the secondary side 14, and atmosphere is drawn into the secondary side through the vent 6. Further, the atmosphere is also drawn into the primary side 13 to disrupt the vacuum therein.

Filed: 1980-09-22
Abstract: PURPOSE:To reduce the scale of hardware without requiring a high-precision filter for a receiving circuit, by sending a priority request and information on a power failure by a common informaton signal and by recognizing that a subordinate station has a power failure when no data is sent withing a constant time. CONSTITUTION:A priority request signal c1 and a power-failure information signal d1 are ORed by an OR circuit 28 to be inputted as a common information signal to an information signal transmitter 29, thereby transmitting it to a master station 1 as a signal of an information signal transmission band. This information signal e1 is received by an information signal receiver 17 of the master station 1 and then fetched in a master-station logical circuit 11. Then, the circuit 11 judged the signal e1 as a priority request signal ci and sends a call signal a subordinate station (i). When the information signal is judged to be the priority request signal, data is sent from the subordinate station (i) and priority data fetching operation is carried out. When the information signal is judged to be the power-failure information signal, it is impossible to send the data in response to the call because the subordinate station (i) has the power failure, and then the master station monitors the data response time of the subordinate station to recognize the occurrence of the power failure to display that.
