A fuel cell system according to the present invention comprises a hydrogen generator including a burner which is detachably accommodated in the hydrogen generator in a manner to allow the burner to be detached from and attached to the hydrogen generator through the top of the hydrogen generator, a stack configured to generate power by causing hydrogen generated by the hydrogen generator and an oxidizing gas to react with each other, and a main body package which includes at least a top plate and within which the hydrogen generator and the stack are disposed. Detachable piping, which is detachably configured, is provided above the hydrogen generator. Space that is formed above the burner when the detachable piping is removed from the main body package has a size larger than or equal to the size of the burner.

The invention allows for restriction of radial and axial movements of a shaft by a simple structure. A shaft supporting structure includes a base () provided with a bearing (), and a first shaft () arranged at the bearing (). The shaft supporting structure further includes a helical torsion spring () fitted on the first shaft (). The base () includes a first engagement hole (), and a hooked section () engaging with first and second arm sections () of the helical torsion spring (), respectively. The helical torsion spring () presses the first shaft () onto the bearing () in a radial direction of the shaft by an elastic force generated by engagement between the first arm section () and the first engagement hole () of the base (), and engagement between the second arm section () and the hooked section () of the base (). A portion of the second arm section () faces an axial end face of the first shaft ().

A video recording apparatus that prevents screen malfunctions due to playback of incomplete frame image data, even when a power failure has occurred while recording frame image data received via a network to a recording medium, and incomplete frame image data has been recorded. The video recording apparatus includes a reception unitthat receives management information attached to each piece of data, a first recording unitthat records the received video data to the recording medium, and a second recording unitthat records position information of the video data to the recording medium. The video recording apparatus quickly specifies damaged data positions by referencing a file length of the video data file, and a position information file

A disc device includes the following: a traverse basethat can be moved between a recording/reproducing position and a standby position, on which an optical pickupand a turntableare mounted; a front coverincluding a disc carrying surfacethat carries a discand an aperturethat is formed in the disc carrying surfaceand allows the turntableto pass through when the traverse baseis moved between the recording/reproducing position and the standby position; and centering membersfor holding and shifting the discto a position where the center of the discis aligned with the center of the turntable. The loading of a disc can be performed in an easy and highly flexible manner.

Disc device with particular loading mechanism

A disc loading device includes a first conveying unit to convey a disc and a second conveying unit to convey a cartridge containing the disc. When the disc is inserted or ejected, the disc is conveyed by the first conveying unit. When the cartridge is inserted or ejected, the cartridge is conveyed by the second conveying unit. When the cartridge is not detected by a cartridge detecting unit, a first conveying unit moving unit moves the first conveying unit to a first position and holds the first conveying unit in the first position, and when the cartridge is detected by the cartridge detecting unit, the first conveying unit moving unit moves the first conveying unit to a second position and holds the first conveying unit in the second position.

A stop command detecting unit detects an operation transition from fast forwarding/rewinding modes to a stop mode, a take-up side reel braking unit and a supply side reel braking unit start a braking operation based on the stop command, and a driving motor of the take-up side reel is driven at a specified current value set by a motor current value setting unit for a specified time set by a current adding time setting unit to provide the take-up side reel with rotary torque in the winding direction. Hence, the supply side reel rotates together with the take-up side reel until the supply side reel is stopped, thereby preventing occurrence of a slack on the tape.

Tape-like recording medium running device

With a magnetic record and playback device that permits rapid switching from fast forward (FF) mode or rewind (REW) mode to playback (FWD) mode, when it is necessary to switch rapidly from fast forward (FF) mode or rewind (REW) mode to playback (FWD) mode, the device is operated in a first take-up mode in which magnetic tape is wound on the rotating head drum, and when it is not necessary to switch rapidly from fast forward (FF) mode or rewind (REW) mode to playback (FWD) mode but is required to increase magnetic tape transport speed, the device is operated in a second take-up mode in which the magnetic tape is not wound on the rotating head drum, whereby it is possible to shorten the fast forward/rewind time by raising the transport speed of the magnetic tape without increasing the load on the magnetic tape or the magnetic head.

Magnetic record and playback device

A tape medium running device which can more correctly detect erroneous detection of a winding diameter, prevent an approach from being made to the end of the magnetic recording tape at high running speed and causing a damage on the tape, and can shorten fast forwarding/rewinding time. In this device, a winding diameter change detecting unit detects a change in winding diameter, and a ratio of a detected change in diameter and a maximum value of changes in winding diameter having been detected previously is compared with a predetermined winding diameter change comparison reference to detect abnormality. Thus, it is possible to prevent any approach from being made to the end of the magnetic recording tape at a high running speed based on an erroneous detection to causing a damage on the tape, and to shorten time for fast forwarding and rewinding.
