Abstract: An intended-usage judger judges an intended usage of an inputted digital imaging signal. A selector selects one or a plurality of signals to be inspected from a group of signals constituting the digital imaging signal based on a result of the judgment by the intended-usage judger. A phase adjuster adjusts a phase of a pulse used when the digital imaging signal is picked up based on an output state of the signal to be inspected.

Abstract: A heat exchanger assembly has a first heat exchanger with a first heat radiating area receiving a first cooling fluid, a second heat exchanger with a second heat radiating area receiving a second cooling fluid and a third heat radiating area receiving a third cooling fluid. In use, the difference in temperature between the first cooling fluid entering and exiting the first heat radiating area is greater than the difference in temperature between the second cooling fluid entering and exiting the second heat radiating area and greater than the difference in temperature between the third cooling fluid entering and exiting the third heat radiating area. The temperature of the second cooling fluid flowing through the second heat radiating area is higher than the temperature of the third cooling fluid flowing through the third heat radiating area.

Abstract: A fuel cell system according to this invention comprises: a pressurizing valve (2a) provided on a cooling water circulation path; a reservoir tank (5) into which the cooling water flows through a pipe (4) when the pressurizing valve (2a) is open; an air supply pipe (13) that is connected to the reservoir tank (5) to supply air for diluting a fuel gas when the fuel gas accumulates in the reservoir tank (5); and a diluted gas exhaust pipe (15) for discharging the diluted fuel gas from the reservoir tank (5).

Abstract: A heat exchanger has a first heat exchanger with a first heat radiating area receiving a first cooling body, a second heat exchanger with a second heat radiating area receiving a second cooling body and a third heat radiating area receiving a third cooling body. In use, the difference in temperature between the first cooling body entering and exiting the first heat radiating area is greater than the difference in temperature between the second cooling body entering and exiting the second heat radiating area and greater than the difference in temperature between the third cooling body entering and exiting the third heat radiating area. The temperature of the second cooling body flowing through the second heat radiating area is higher than the temperature of the third cooling body flowing through the third heat radiating area.

Abstract: A reservoir tank which includes: a container for storing fluid therein, having an inlet through which the fluid flows into the container and an outlet through which the fluid flows out of the container; and a duct provided inside the container, which is connected to the inlet of the container and has a first opening open inside the container. The first opening is located above the outlet of the container and below a surface of the fluid in the container.

Abstract: The moving picture image pickup device of the present invention comprises: a lighting device for performing lighting operation in response to an input of an illumination control pulse; a signal processing unit for calculating luminance of an object based on a signal from an image sensor; and a control unit for adjusting illumination light quantity of the lighting device according to the luminance of the object calculated by the signal processing unit, wherein the control unit changes the luminance of the object in real time by performing feedback control on the illumination light quantity of the lighting device through adjusting pulse width of the illumination control pulse in accordance with the luminance of the object.
