Title: Ink jet recorder
Inventor: KOJIMA TAMOTSU
IPC: B41J2/045
Filed: 1983-04-18
Abstract: PURPOSE:To enhance stability to variation of a meniscus of an ink and enable to obtain favorable recording characteristics, by protruding an ink-ejecting port toward an air-ejecting port to provided a projected part. CONSTITUTION:An electrode 9 is provided on the surface of a nozzle plate 2 so as to surround the air-ejecting port 16. The ink-ejecting port 17 is provided in a nozzle member 19 so as to be faced to the air-ejecting port 16, and a part thereof making contact with sharply deflecting parts of an air flow 18 is projected toward the air-ejecting port 16 to form the projected part. The air flow 18 is deflected more sharply by the effect of the protruding part of the ink-ejecting port 17, and a dead water region of the air flow is generated in proximity to the port 17. There is little pressure gradient of the air flow in the dead water region. Therefore, the ink doest not spout even when the meniscus of the ink formed at the port 17 is slightly varied, so that the stability of the meniscus is enhanced. The cross-sectional shape of the projected part of the nozzle member 21 provided with the ink-ejecting port 20 may be set to be trapezoidal so that air flows smoothly along the surface of the projected part and flows out through the air-ejecting port 23.

Filed: 1979-06-04
Abstract: PURPOSE: To enable self-running without causing an advanced power factor even if a power factor improving unit becomes defective, by providing a power factor improving unit isolating means which is operated by a trouble detector for the power factor improving unit.  
     CONSTITUTION: A trouble switch unit SW comprises a normally-closed main contact MC, a trip coil and a normally-open interlocked contact CC. When the trip coil is energized, the main contact MC is opened and the interlocked contact CC is closed in connection with the opening of the main contact. The power factor improving unit PFD is connected to the secondary side of a main transformer MT through the main contact MC. A phase detector PHD receives the input voltage and current levels of the transformer MT. The phase detector produces an output signal when a power factor exceeds a predetermined range. When a trouble detector TD receives the output signal, the trip coil TC is energized to open the main contact MC of the trouble switch SW and a power factor improving capacitor C is isolated to prevent the power factor from being advanced.

Title: Device for rewinding film
Inventor: TAKEUCHI YASUSHI
IPC: B65H20/32
Filed: 1987-03-25
Abstract: PURPOSE:To reduce variance in the tension of a film taken up by a drive roll by employing a control device for controlling the brake force of a brake device according to the output signal of a position detection device. CONSTITUTION:When the tension of a film 1 decreases, the film 1 between guide rolls 2 and 3 slackens, a position detection device 15 detects the slack and makes a control device 14 work, and the brake force of a brake device 12 is increased. As a result, rotation of a shaft core 9 is also braked and the rewinding tension of a roll-like film 10, namely the tension of the film 1, increases. When the film tension increases on the contrary, slack of the film 1 between guide rolls 2 and 3 due to suction forces by a suction device 7 decreases, the position detection device 15 detects the decrease in the slack to make the control device 14 work to reduce the brake force of the brake device 12. As a result, rotation of the shaft core 9 becomes easier and the rewinding force of the roll-like film 10, namely the tension of the film 1, decreases.
