A hydrogen supply system includes: a hydrogen production device; a hydrogen flow line through which hydrogen produced by the hydrogen production devices circulated; a buffer tank that is provided in the hydrogen flow line on the downstream side of the hydrogen production device; a compressor that is provided in the hydrogen flow line on a downstream side of the buffer tank; a bypass line that bypasses a portion of the hydrogen flow line and has a downstream-side end portion communicating with the hydrogen flow line on the downstream side of the buffer tank; and a storage tank that is provided in the bypass line and is capable of storing the hydrogen.

Hydrogen supply system, hydrogen-consuming plant provided with hydrogen supply system, and method for supplying hydrogen to hydrogen-consuming unit

A gas liquefaction apparatus includes at least a source-gas supply line that supplies source gas; a room-temperature heat exchanger, a preliminary-cooling heat exchanger, and a liquefaction/supercooling heat exchanger that are provided in series sequentially in the source-gas supply line and that cool the source gas; a separation drum that separates the source gas containing a condensate, which has been cooled by heat exchange up to a liquefaction temperature of the source gas or below, into a gas component and a liquefied component; and a refrigerant-gas supply line that uses a gas component separated by the separation drum as refrigerant gas to supply the refrigerant gas in a direction opposite to a supply direction of the source gas, in order of the liquefaction/supercooling heat exchanger, the preliminary-cooling heat exchanger, and the room-temperature heat exchanger.

Gas liquefaction apparatus and gas liquefaction method

A method includes a first step of, with a CO.HS stripper maintained to have a pressure higher than atmospheric pressure, from the ammonia-containing wastewater, discharging COand HS in a form of gas having a low moisture concentration from a tower top of the CO.HS stripper while discharging an ammonia-containing solution from a tower bottom of the CO.HS stripper; a second step of introducing the ammonia-containing solution obtained after the first step into an ammonia stripper which is maintained to have a lower pressure than that of the CO.HS stripper, and thereby discharging a gas rich in ammonia containing a small amount of HS and COfrom a tower top of the ammonia stripper while discharging water usable as industrial water from a tower bottom of the ammonia stripper; and a third step of introducing the ammonia rich gas obtained after the second step into a washing tower which is maintained to have a lower pressure than that of the ammonia stripper, and thereby discharging a wastewater containing a Na compound from a tower bottom of the washing tower while discharging a HS-free gas rich in ammonia from a tower top of the washing tower.

Ammonia recovery device and recovery method

In a pen input and output unit for inputting data by contacting a pen on an input surface of a tablet device and for displaying the input data, display data is updated by detecting that the pen is traveled by a predetermined distance while the pen is in contact with the input surface of the tablet device. The display data can continuously be updated by sliding, reciprocally traveling, circulating or the like the pen on the input surface.

Pen input and output unit

Under a transparent board-like digitizer, a screen of the same size as that of the digitizer is positioned. Scenes of a display device is shown on the screen. A co-ordinates standard of the digitizer is set to be identical with that of the screen. Consequently, the point indicated on the digitizer of a first cursor device is shown at a position corresponding to that of the point indicated by means of the cursor. In a circle drawing mode of the digitizer, when the operator places the cursor device on the digitizer and co-ordinates data are inputted to a computer, a plot circle corresponding to the co-ordinates data is displayed on the screen. When the operator makes the plot circle by means of the cursor device, the computer selects a radial input system. On the other hand, when the operator uses the cursor device and selects the exterior of the plot circle, a transient point input system is selected. In an operation of the radial input system, the operator uses a key board or a command menu displayed on the screen in order to carry out an input operation. When the operator inputs a radial r to the computer, a circle with its radial r and its center corresponding to the center of the plot circle is drawn or displayed on the screen. In the transient point input system of the input device, when the operator hits any point on the digitizer by means of the cursor device, a circle having its center corresponding to the center of the plot circle and having its line passing on the point the cursor device hits is drawn.

Input device for CAD

A transparent board-like digitizer is placed near a display screen. Images of the same size as that of the digitizer images entered on the digitizer are displayed on the screen. A co-ordinates standard of the digitizer is set to be identical with that of the screen. Thereby, the point indicated on the digitizer of a first cursor device is shown at a position corresponding to that of the point indicated by the cursor. The screen displays right-angle scale lines controlled by a second cursor device on the digitizer. The right-angle scale lines can carry out parallel movements and rotations on the screen. When a straight line drawing is carried out, an operator indicates two points on the digitizer by means of the first and the second cursor devices and inputs the data of such two points, whereby a straight line connecting these two points, dimension supplemental lines in parallel with the right-angle scaling lines, dimension lines extending between the two points, and a dimension figure, respectively, are displayed on the screen.

In a reader in which a tablet and a cursor device are connected electrically to the reader and an indicated position of the cursor device on the tablet is converted to a coordinate signal to be outputted, the improved reader in which two cursor devices are connected to the reader, and the first cursor device is retained by one hand, and the second cursor device is retained by the other hand, and the two cursor devices are manipulated by both hands of the operator so as to shift them on the tablet whereby the reader outputs the coordinate signal for the drawing of a graphic, and setting the command to a CPU on the basis of the indication of each cursor device.
