In the present invention, a coal gasification combined power generation facility comprises: a feed water supply line (); a condensate pump () and an intermediate-pressure feed water pump (); a turbine bypass line () that bypasses a steam turbine and supplies steam to the condenser (); and a spray water line () that supplies the feed water to the turbine bypass line (). The coal gasification combined power generation facility has a normal operation mode and a bypass operation mode, and in the bypass operation mode, a control device () supplies the feed water to the turbine bypass line () and performs a first opening degree control to control the opening degree of the supply adjustment valve so that the amount of feed water supplied to the exhaust heat recovery boiler becomes less than that in the normal operation mode.

Combined power generation plant and combined power generation plant control method

To provide a condensate flow rate control device and a control method for a power plant which improve responsiveness to frequency fluctuations or requested load changes and can suppress frequency fluctuations with precision or improve precision with which output power conforms to requested load instructions. A power plant to which a condensate flow rate control device is adapted includes a deaerator to which condensate generated by a condenser is supplied via a deaerator water level adjustment valve and into which bleed steam from a steam turbine is introduced. The condensate flow rate control device has a water level adjustment unit for executing condensate flow rate control, wherein the water level adjustment unit adjusts pressure in a condensate flow path extending from the deaerator water level adjustment valve to the deaerator so that inputted frequency fluctuations are suppressed or an output value of a generator conforms to inputted requested load changes.

A ship powered by an internal combustion engine () and an electric motor () connected to a propeller () powered by surplus electric power obtained by a thermal discharge recovery system has a controller including a feedback control section for controlling a base amount of fuel injected to the internal combustion engine () based on the difference between the target number of rotation of the propeller given by the operator and the real number of rotation, and a feed-forward control section having a means () for calculating an overall power output and a means () for calculating a correction in the amount of fuel injected to the internal combustion engine based on the overall power output and the number of rotation of the propeller. The base amount of fuel is corrected by subtracting the correction obtained by the feed-forward section from the base amount of fuel calculated by the feedback control section whereby preventing a rapid change in the speed of the ship due to rapid change in ship loads.

The object of the present invention is to provide a photographing device, iris image input device and iris image input method capable of rapidly and accurately acquiring an iris pattern code of a person to be identified regardless of the height of the person to be identified. In order to achieve this object, with an iris image input device of the present invention, a portable photographing device is connected to a recognition unit and a monitor. The person to be identified that is to photograph their iris uses this iris input device in the following manner. The person to be identified takes the photographing device in one hand, lines up the photographing device with the eye with the iris to be photographed and photographs the iris. While doing this, because the iris image of the eye of the person to be identified photographed by the photographing device is displayed at a monitor of the iris image input device, the person to be identified can adjust the position of the photographing device while looking at the image with their other eye in such a manner that the focal point of the photographing device lines up with the eye being photographed. The iris image input device can therefore acquire iris pattern code for the person to be identified rapidly and accurately.

An object of the invention is to provide a photographing apparatus capable of verifying with ease that a transaction processing unit has been wrongfully utilized, and at the same time, reducing an amount of image data for each case of transaction processing while lowering the cost thereof, and a monitoring system using the photographing apparatus. To this end, the photographing apparatus according to the invention includes an image forming element having an image forming face, a photographing field angle dividing arrangement for dividing a photographing field angle into photographing field angles A, B so as to correspond with a plurality of sites to be photographed, and forming an image of the respective sites to be photographed on the image forming element, and an image data generation arrangement for generating image data of the respective sites to be photographed on the basis of output of the image forming element. In this case, since the images of the plurality of the sites to be photographed can be formed on the image forming face of one image forming element, the plurality of the sites to be photographed can be simultaneously photographed with one unit of image pickup camera. It becomes therefore unnecessary to install a plurality of the image pickup camera in order to photograph the respective sites to be photographed.

A remote work supporting system includes a photographing device for photographing a work target machine that is to be worked on by a first operator, a first display for displaying an image of the target machine to the first operator, a second display for displaying the same image to a second operator, an operation device to be operated by the second operator, and an instruction displaying device for displaying contents of instructions in the first display based on operations made on the operation device. Since the instruction contents are displayed in the first display according to the operations made on the operation device by the second operator, the first and second operators can share considerable amount of information.

Remote work supporting system

An image-input device includes a camera for capturing an iris pattern, and a personal computer for displaying the captured iris image. The computer has software for registering iris data and for comparing iris data. A half mirror is connected to the camera. The camera is mounted to the display of the computer. The half mirror, which transmits a visible light element and reflects near infrared light, is disposed in front of the display when the camera is connected to the computer. The iris of a user is captured by the camera while the user watches the display of the computer through the half mirror.
