A focus control circuit is installed in an image pickup apparatus including a lens, a driver element for adjusting the position of the lens, and a position detecting element for detecting the position of the lens. An equalizer included in the focus control circuit generates a drive signal used to adjust the position of the lens to a position to be set, based on a difference between the position of the lens identified by the position detecting element and the set position. When an instruction to vary a target position of the lens is received externally, a position setting unit included in the focus control circuit sets sequentially a plurality of positions in a range covering a new target position and a previous target position, to the equalizer before the new target position is reached from the previous target position.

摘要:
A data reproducing controller for operating a device for reproducing data at a high speed, which is recorded on a disc and includes an error correction code. A PI correction circuit performs an error correction process on a PI and causes a completion signal to go high whenever processing of 182 bytes of data is completed. A counter circuit sequentially increments a count value whenever the completion signal goes high. A determination circuit compares the count value with a predetermined set value and determines whether the data of which PI has undergone the error correction process is a PO row based on the comparison. The determination circuit causes a first control signal to go low when the data is a PO row. A descrambling circuit skips the data that is determined to be a PO row.

Provided is a tetrafluoroethylene copolymer consisting of a unit based on tetrafluoroethylene and a unit based on a monomer represented by CF2═CFORf1Rf2 (where Rf1 is a polyfluoroalkylene group which may contain an etheric oxygen atom and Rf2 is a polyfluorocycloalkyl group which may contain an etheric oxygen atom), wherein a content of the latter is from 0.005 to 0.5% by mass. The tetrafluoroethylene copolymer is excellent both in paste extrudability and in heat resistance, has characteristics such as excellent transparency of a molded product, and is suitably applicable to paste extrusion and compression molding.
摘要:
A data buffer receives and temporarily stores data including a product code enabling error correction in first and second directions. An exclusive-OR operation circuit uses an error amount detected by error correction in the first direction and data stored in a storage element to calculate a first error check result. A PI direction error-checking circuit according to the first error check result performs error check after error correction in the first direction. A PO direction partial error-checking circuit and a PO direction aggregate error-checking circuit use an error amount detected in error correction in the second direction and calculate a second error check result. The first and second error check results are used to generate a final error check result by an exclusive-OR operation circuit.
