Abstract: A flow path device includes a storage chamber, an inlet, a flow path, and a projection. The storage chamber includes a ceiling surface and a bottom surface, and is capable of storing a specimen. The inlet is one through which an outside of the storage chamber and the storage chamber communicate with each other to allow the specimen to flow into the storage chamber from the outside of the storage chamber. The flow path is connected to an upper portion of the storage chamber at a location situated away from the inlet. The specimen is allowed to flow out into the flow path from the storage chamber. The projection projects toward the bottom surface of the storage chamber from the ceiling surface of the storage chamber, and is positioned between the inlet and the flow path.

Abstract: The disk recording apparatus and method are arranged to specify a recording address and a recording position on an optical disk with a wobble PM (phase modulation) format through the use of a wobble reproduced signal and a track reproduced signal. The recording apparatus operates to detect address information and a synchronous signal on the optical disk that correspond with the wobble reproduced signal and the track reproduced signal sent from the optical disk respectively. Then, the address information required for specifying a disk recording track and the synchronizing timing required for specifying a linking position are selected from the detected states.

Abstract: An information recording method and apparatus records information signals having data signals and synchronizing signal patterns inserted at predetermined intervals of the data signals on a recording medium with a binary level by using a coding rule without a DC free property. The synchronizing signal patterns are inserted into the data at intervals of a fixed block length and are supplied to a recording apparatus as a mark/space pattern (record signal pattern). The data are converted into the same pattern as the mark/space pattern and an accumulated value (corresponding to the average DC value) for each block length is counted. The sum and the difference of an output of a memory which stores the accumulated values from the head of the sector to the (N-1)-st block, and the accumulated value of the N-th block, are compared with each other in absolute value.
