Abstract:
An imaging apparatus, comprising: a first recording module, which has a first initialization time from initialization to coming into a recordable condition; a second recording module which has a second initialization time from initialization to coming into a recordable condition, being longer than the first initialization time; a mode switching module, which is configure to switch over a power OFF mode, a mode for recording into the first recording module, and a mode for recording into the second recording module, wherein the mode exchange switch, which is configured to exchange the mode in an order from the power OFF mode to the mode for recording into the first recording module, and to the mode for recording into the second recording module, whereby shortening an apparent initializations time of the recording module having a long initialization time, while using a high-speed initialization characteristic of the recording module having a short initialization time effectively, thereby obtaining an improvement on the operability for a user.
Abstract:
Determining the degree of satisfaction of a user of network services quantitatively is difficult. A service quality management model defining means for defining the service condition and network depending relation and evaluation conditions, a means for storing the model in a DB, a service condition monitoring means for monitoring the transition of the service condition, and a service quality calculating and evaluating means for calculating service availability and executing special service maintaining and relieving measures are provided.
Abstract:
In order to reliably avoid freezing in the generation stop state during intermittent operation, in the control device of the present invention that controls a fuel cell system to operate intermittently by switching between the generation state and the generation stop state of a fuel cell, it is determined whether to stop the generation operation during intermittent operation based on at least the temperature of a specific component that contains moisture from among the components constituting the fuel cell system. A valve, a passage, or a humidifier arranged on a flow path for a fuel gas or oxidizing gas may be selected as the specific component mentioned above. The temperature of the specific component is measured either directly by a temperature sensor provided corresponding to the specific component or indirectly based on either the operating state of the fuel cell system or the external air temperature.
Abstract:
Provided is a fuel cell system, which can inform the user of the input of a control command for low-temperature countermeasures, if necessary, at a proper timing. A control unit decides whether or not an ambient temperature To of a remote-part temperature is lower than 0° C. for the time period from a start request to a stop request of the system. The control unit informs, when it decides that either temperature is lower than 0° C., the user of a message for urging the input of the control command for the low-temperature countermeasures.

Abstract:
In a central portion of inner tube 28 of combustor 20, pilot fuel nozzle 22 and pilot cone 33 are arranged and main fuel nozzles 21 and main swirlers 32 therearound. Air intake portion (X-1) is provided with rectifier tube 11 for making air intake uniform. In air intake portion (X-2), air holes of appropriate number of pieces are provided in circumferential wall of the inner tube 28. In main swirler portion (X-3) and pilot cone portion (X-4), bolt joint of the main swirlers 32 is employed and optimized welded structure having less influence of thermal stress of the pilot swirler 33 is employed, respectively. Tail tube cooling portion (X-5) is provided with cooling structure having less influence of thermal stress to cool flange 71 portion of tail tube 24 uniformly. By the improvements in the portions (X-1) to (X-5), obstacles in attaining higher temperature in the combustor 20 is dissolved and combustor performance is enhanced.

Abstract:
Liquid fuel purge device uses water, not compressed air as in the prior art, thereby prevented are rapid load change of gas turbine due to sudden discharge of liquid fuel and coking of remaining liquid fuel. Upon supply of liquid fuel to fuel nozzle (05) being stopped, water purge system (15) having stop valve (16) supplies water into fuel system including liquid fuel system (08) and fuel nozzle (05) and liquid fuel remaining therein is purged by water into combustion chamber (013) from the fuel nozzle (05).
