A fluid-impermeable composite hose has a wall including a laminated layer formed by longitudinally lapping a laminated sheet which contains a metallic foil, or a metallic layer formed by vapor deposition. The laminated layer is bound with thread wound about it at a density not exceeding 20%, and bound to an extent forming constrictions therein if required. The thread prevents the deformation in cross section of the hose and the separation of the overlapping edge portions of the laminated sheet which might otherwise be caused by the bending resistance of the laminated sheet. The constrictions improve the flexibility of the hose.

In a recording and reproducing apparatus for a disc-shaped recording medium, and a defect substitution method for a disc-shaped recording medium, whether reproduction of recorded data is good is determined by sector unit and not by product code unit, defective sector discrimination is performed by sector unit, and only sectors determined defective are alternately recorded, when using a recording format in which data that is error detection and correction coded with a product code is segmented and recorded to a plurality of sectors.

An optical disk according to the present invention includes a first track having a spiral shape and a second track having a spiral shape, the first track and the second track adjoining each other, and information being recorded on or reproduced from the first track and the second track. The optical disk further includes an address region including: a first address block formed so as to be on both the first track and the second track adjoining the first track on an inner periphery side; and a second address block formed so as to be on both the first track and the second track adjoining the first track on an outer periphery side.

In an information recording medium, wherein data are reproduced in a sector unit, a file area for recording the file systems of a plurality of operating systems and a discrimination area for recording the position data on the file systems in the file area are provided. Then, the same data recorded in the recording medium can be managed by the operating systems of different file management systems. In a recording apparatus for reproducing data from the information recording medium, the position data are reproduced from the discrimination area and the data recorded in the information recording medium can be read by converting the position data to an actual sector address in the information recording medium. Thus, a file can by reproduced from the recording medium with either of the operating systems.

A read only type optical disc, and disc drive apparatus for reading/additionally writing data into the disc. The disc has a recording material formed in all of the tracks by which data can be additionally recorded on the disc. This optical disc has a plurality of sectors forming a data read-only area and a write/read area. Each area has track sectors each having a sector identifier portion in which address information is recorded and a data field portion to record data. Data-field identification flags indicativ of the read-only area and the write/read area are recorded in the respective identifier portions. On reading or writing this optical disc, the data field identification flag is detected to identify the kind of related area i.e., rea-only area or write/read area. Thus, it is possible to avoid erroneous recording of data into the read-only area. Upon reading operation, waveform equalization and binary-clipping level of reproduction signals can be well controlled. The gain of the servo loop can be switched. The track searching operation can be stably performed. The data reading and data writing into the data write/read area can be improved.

The present invention relates to an optical disk having a control track. The control track is divided into sectors in a manner similarly to a data track to record data and comprises a plurality of sectors. Each sector is composed of a sector identifying portion ID in which address information is recorded and a control field portion CF in which control data is recorded. The control field portion CF has the same format as the sector identifying portion ID. The control data is divided into recording data units in the control field portion CF and recorded. An identification flag is provided for each of the sector identifying portion ID and control field portion CF. The control track is searched by the address information in the sector identifying portion ID. The address data and control data are selected by use of the identifying flags in the sector identifying portion ID and control field portion CF, and they are read, then the control data are reassembled in order by using the address data of the sector identifying portion ID.

Disclosed is an information recording/reproducing apparatus which uses a rewritable recording medium having a sector structure, and in which a data writing gate signal and a data erasing gate signal are reproduced on the basis of an ID detection signal of a target sector, while a data reading gate signal and a marking gate signal are produced on the basis of the ID detection signal of the target sector or on the basis of an ID detection signal of a sector located N sectors before the target one, so that when data is to be renewed in a specific sector from which no ID detection signal can be obtained, marking is performed in the specific sector on the basis of an ID detection signal of a sector located N sectors before the specific sector and new data are rewritten into a substitutive sector, whereby it is possible to perform data erasing and data recording in a target sector with high reliability and high positional accuracy and it is possible to shorten gaps respectively in front and rear of a data field to thereby make it possible to efficiently use a data area.

The present invention relates to semiconductor inspection and provides a technology capable of efficiently detecting a systematic defect. In the present system, with regard to the process (S7, S8) of matching hot spot (HS) points that can be simulated in advance and defect points obtained as a result of a visual inspection each other and the unmatched defect points, a process (S6, S9) of classifying the defect points into groups based on similarity of pattern layout at the defect points to determine the defects belonging to a pattern layout where defects frequently occur, thereby reliably detecting the systematic defect. Also, with a process (S11) of acquiring an uneven distribution in a defect occurrence distribution on a wafer, the systematic defect occurring due to topography of the wafer can also be detected.
摘要:
In automatic defect classification, a classification recipe must be set for each defect observation device. If a plurality of devices operate at the same stage, the classification class in the classification recipes must be the same. Problems have arisen whereby differences occur in the classification class in different devices when a new classification recipe is created. This defect classification system has a classification recipe storage unit; an information specification unit, the stage of a stored image, and device information. A corresponding defect specification unit specifies images of the same type of defect from images obtained from different image pickup devices at the same stage. An image conversion unit converts the images obtained from the different image pickup devices at the same stage into comparable similar images; and a recipe update unit records the classification classes in the classification recipes corresponding to the specified images of the same type of defect.
摘要:
A defect is efficiently and effectively classified by accurately determining the state of overlap between a design layout pattern and the defect. This leads to simple identification of a systematic defect. A defective image obtained through defect inspection or review of a semiconductor device is automatically pattern-matched with design layout data. A defect is superimposed on a design layout pattern for at least one layer of a target layer, a layer immediately above the target layer, and a layer immediately below the target layer. The state of overlap of the defect is determined as within the pattern, over the pattern, or outside the pattern, and the defect is automatically classified.
