Title: Ink jet recorder
Inventor: HAYAKAWA TAKESHI
IPC: B41J2/055
Filed: 1992-05-19
Abstract: PURPOSE:To enable a high speed printing by using electromagnetic force to be performed in a low power consumption. CONSTITUTION:A passage substrate 1 and a cover plate 4 are formed by a plastic magnet material consisting of magnetic powder and thermoplastic resin. Then, they are arranged so that their opposed surfaces attract magnetically each other. A reinforcing board 3 having a hole part 3a corresponding to a pressure generating chamber 2b is laid between both plates 1, 4. Further, a coil 5 (an electromagnetic force generator) is attached onto the cover plate 4. In non-printing voltage is not impressed to the coil 5. The cover plate 4 and the passage substrate 1 which are preliminarily magnetized are attracted to each other by their polarities, and a volume of the pressure generating chamber 2b corresponding to the hole part 3a becomes extremely small. In printing voltage is once impressed to the coil 5 to be acted as an electromagnet. After alienating the cover plate 4 from the passage substrate 4, impression of voltage is stopped immediately, and the cover plate 4 is made to approach the passage substrate 1. The volume of the pressure generating chamber 2b is decreased, and ink is injected.

Filed: 1983-07-12
Abstract: PURPOSE:To make full use of a variable speed pump as well as to improve a flow control function, by calculating a cut-off operating point in the variable speed pump on the basis of an output signal out of a conveying pressure gauge measuring hydraulic pressure at the conveying side and another output signal out of a conveying flow meter. CONSTITUTION:In case of a system controlling a conveying flow rate with a variable speed pump 1 and plural units of fixed speed pumps 2, both the existing conveying pressure value and conveying flow value are taken into an arithmetic unit 8 by means of a conveying pressure gauge 7 and a conveying flow meter 3. At this arithmetic unit 8, a cut-off operating point in the variable speed pump is found and the result is outputted to a flow adjustment and pump number control device 4. As a result, for a while reaching to the cut-off operating point, a variable speed signal is outputted to a speed controller 6 of the variable speed pump, while at the cut-off operating point, a fixed pump decreasing command is outputted so that a flow control function is thus improved.

Title: Vapor-liquid separation chamber
Inventor: MOTOHASHI TOSHIAKI
IPC: B01D19/00
Filed: 1988-05-25
Abstract: PURPOSE:To secure the function of gas flow control valve and reduce size by a method wherein a gas mixing liquid inlet port is provided, a liquid flow control valve is mounted at the lower part, and the gas flow control valve which opens and closes in two stages by a float is installed at the upper part. CONSTITUTION:When a vapor-liquid separation chamber 8 is filled with liquid due to malfunction such as a failure of a liquid flow control valve 10 or liquid flow-in from another pump device, for example, a float 21 floats to a position shown by a chain line. This swings a float lever 20 counterclockwise, arises a valve lever 22 to close an opening 14b with a valve body 30 to prevent liquid from flowing out. In case of liquid flow-in from another pump device, the liquid level drops when this pump 3 is driven to permit the liquid to flow out to a flow path 15. At this time, the float lever 20 slightly swings clockwise with the own wt. of the float 21 to have the valve lever lowered to open a valve hole 31. If gas escapes from the small hole 31 into a path 14a and the inner pressure drops to a level low enough to open the valve body 30, the float lever 20 further swings with the own weight of the float 21. This permits a pin 22a to be engaged with a lower rim of a long hole 32 to have the valve body 30 lowered and open the valve.
