An ink feeding mechanism includes an ink reservoir 31, a subtank 32 for temporarily storing ink, a decompression channel 44 for decompressing the subtank 32 to a fixed pressure, an ink force-feed channel 41 interconnecting the ink reservoir 31 and subtank 32, a first switch valve 35 mounted on the ink force-feed channel 41, a communication channel 43 interconnecting the subtank 32 and an inkjet head 10, an ink circulating channel 42 interconnecting the communication channel 43 and ink reservoir 31, and a second switch valve 34 mounted on the ink circulating channel 42. A lid member 51 forming part of a chamber has a pressure regulating channel 45 connected thereto, which is connected also to a force-feed channel 46 with a pressure pump 37 mounted thereon, and an exhaust channel 47 with an exhaust pump 38 mounted thereon.

An intermediate fluid type vaporizer has an intermediate fluid evaporator for containing an intermediate fluid. The intermediate fluid evaporator includes heat source tubes for evaporating the intermediate fluid, and a low-temperature liquid evaporating section for evaporating a low-temperature liquid by exchanging heat between the low-temperature liquid and the evaporated intermediate fluid. In the intermediate fluid evaporator, members for dividing the intermediate fluid, and cover plates for covering both ends of the intermediate fluid level from above are provided to prevent the intermediate fluid level from changing due to the shaking of the intermediate fluid evaporator itself. This vaporizer and an LNG tank are mounted on a ship so as to vaporize LNG in the ship and to supply the LNG to an onshore consumer.

An object of the present invention is to minimize a volume of a hollow body by a combination of a horizontal H-letter shaped type gas-liquid separator and a plurality of plate-fin heat exchangers having a larger heat exchange performance per volume. In the present heat exchanging apparatus, fluid and refrigerants flow about in the hollow body through pipes while gas and liquid phases of the refrigerants are repeatedly separated and mixed for heat exchange between the fluid and the refrigerants. The apparatus comprises a plurality of plate-fin heat exchangers for exchanging heat between the refrigerants and the fluid, and a gas-liquid separator including upper and lower accommodation portions which are hollow cylinders laid in a horizontal direction both ends of which are airtightly sealed and an intermediate accommodation portion which connects the upper accommodation portion to the lower accommodation portion so as to form a sideways H-letter shape.

An apparatus for uniformly distributing a liquid having dual gaseous and liquid phases for use with a heat exchanger is disclosed. A liquid spreading device of the apparatus includes a main pipe extending along the full length of a header of the apparatus, and a plurality of branch pipes connected to the main pipe and extending perpendicularly to the main pipe just above and along the full width of descending flow entrances of a core of the heat exchanger. Each branch pipe has a plurality of liquid spreading holes perforated in a predetermined spaced relationship at the bottom thereof. Thus, liquid can be distributed from the apparatus substantially uniformly within a deviation of, for example, .+-.10 percent.

A heat exchanging unit is provided that includes a closed vessel separated into first and second compartments by a vertical partition plate thereby leaving a passage above the vertical partition plate. The first compartment has a cooling medium inlet pipe connected thereto, and a through pipe, through which a fluid to be cooled is passed. The through pipe is arranged to pass through the first compartment and includes a heat exchange member placed at a location lower than the top of the vertical partition plate. The second compartment is provided with a demister, and a cooling medium gas outlet pipe connected to the demister. A cooling medium liquid outlet pipe is connected to the second compartment. The heat exchanging unit is preferably used as part of a combined heat exchanging apparatus formed by combining the heat exchanging unit with a mist processing unit, or as part of a multistage heat exchanging apparatus formed by integrating two or more of the heat exchanging units.

An induction heating cooker has a rectifier (13) for producing pulsating DC current, an inverter (14) which receives the pulsating current given from the rectifier (13) and produces a high frequency output current and a load circuit (15) including an output coil (21) and a resonance capacitor (22) connected in series to each other to receive high frequency output signal from the inverter, and the variation or adjustment of output electromagnetic power is made by changing duty ratio of the high frequency output current of the inverter by giving variable duty ratio setting signals to switching elements (Qa, Qb) in the inverter 14; the frequency of the high frequency output current of the inverter 14 is fixed, and therefore, unpleasant interference sound is not generated at parallel simultaneous operation.

With the use of three inverter circuits controlled by a single processor, the controller of the motor-driving apparatus provides a rotation drum-driving motor, a compressor-driving motor and a blow fan-driving motor with a simultaneous sinusoidal-wave control. The configuration above offers stable sinusoidal-wave drive, reducing vibration noise of the rotation drum, the compressor and the blow fan.
