Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of the optical axis slippage even if an objective lens is set opposite to an optical disk is made to perform a tracking and also to detect the tilt of the disk without using an exclusive sensor device. SOLUTION: The luminous flux emitted from a laser beam source 2 in the tracking direction is deflected in the jitter direction by a movable deflection means, the luminous flux is deflected in the focusing direction by a fixed deflection means, and made incident on an objective lens 7. The lens 7 and the movable deflection means are tracked in a single body by a mobile interlocking mechanism 27, so that the optical axis slippage is prevented. And also, a laser beam is divided into the main luminous flux and the secondary luminous flux and formed into the images between the tracks of an optical disk 11. The push- pull signals are produced from plural beams reflected on the disk 11 and then added together, and the tilt signals corresponding to the tilts of the disk 11 are generated.

A switching device 105B is connected to the side of a data link receiver 107B at this time. The decoded data are processed in an operating part 103B for monitoring differential position measurement. Then, the data are transmitted to a monitor part 109A of the system A. At this time, a GPS receiver 102B of the system B is used as the monitor for the differential position measurement. Then, the roles are changed.  When the system B performs the transmission, the system A becomes the monitor station for the system B in synchronization, and the same processing described above is performed.

Abstract: PROBLEM TO BE SOLVED: To simplify formation, miniaturization of a device and decrease cost, from the standpoint of improving the operational efficiency of a fuel cell. SOLUTION: Each stacked single cells 11 has a flow-adjusting mechanism 40 in a discharge path 26a of air (electrode passing air), which passes through a gas-diffusion electrode 16 (anode) along its electrode surface. The flow- adjusting mechanism 40 has a gas-humidity inductive member 41, which is exposed to the electrode passing air and also expands or contracts corresponding to the air humidity, and a gas shielding member 42 which is supported by the gas-humidity inductive member 41 and is movable along an edge inclined surface 12b. Therefore, when air is supplied to a cell electrode 14, the gas-humidity inductive member 41 expands or contracts spontaneously corresponding to the air humidity, and the gas shielding member 42 is moved along the edge inclined surface 12b, following the expansion or the contraction.  Consequently, an interval between a shielding part 44 of the gas shielding member 42 and an edge under surface 12a of a separator 12, namely, the opening width of the discharge bath 26a, is changed from Ka to Kb or Kc, to thereby adjust the flow of the air passing through the anode.
