摘要:
The invention related to a method for determining a silicon wafer in which the interstitial oxygen concentration of a pulled silicon wafer is calculated on the basis of a light transmission characteristic measured by utilizing parallel polarized light incident at the brewster angle into the pulled silicon wafer and a further light transmission characteristic measured by utilizing parallel polarized light incident at the brewster angle into the floating zone silicon wafer function as a reference silicon wafer. The interstitial oxygen concentration value of the pulled silicon wafer is compared with a reference value to determine a defect in pulled silicon wafer.

摘要:
An electronic device includes a frame having a frame member with a frame connector. The frame defines a component cavity. The electronic device also includes a user interface coupled to the frame that is visible external of the frame, with the user interlace displaying data to an operator. A user input is coupled to the frame member and includes a terminal electrically coupled to the frame connector. A circuit board is received in the component cavity and is operably coupled to the user interface. The circuit board is electrically connected to the frame connector at a separable interface. The user input can pick up a signal from anywhere on the electronic device based on an action of touching, handling or placing and process that signal to cause a predetermined effect. The signal from the user input is transferred to the user interface via the frame connector and the circuit board.

An optical disk includes a first area on which user information is recorded, and a second area in which a plurality of marks radially extending are arranged in a track direction in the optical disk. Information about the reflectance of the optical disk is recorded in the second area. It is intended to optimize the amplification factor of the reproduced signal on the basis of the information about the reflectance of the optical disk in the second area. Control data and user data can be reproduced quickly and highly reliably without depending on the relationship between the reflectances of a recording area and a non-recorded area of the optical disk.

An optical material having a high birefringence and a small absolute value of a photoelastic coefficient is provided by use of a resin composition for an optical material comprising a resin (a) having a positive photoelastic coefficient and a negative inherent birefringence and a resin (b) having a negative photoelastic coefficient and a negative inherent birefringence.
摘要:
An optical disk includes a substrate which is formed with a plurality of grooves, and a recording layer which is provided on the substrate and which is formed of a phase-change material containing Bi, Ge, and Te. Each of the grooves is provided with a header section on which address information of the groove is recorded. The header section is formed by deflecting the grooves in the radial direction. The header sections of the respective grooves are arranged and aligned in the radial direction. Even when the address information of the predetermined groove was failed to be reproduced, the address information of the predetermined groove is specified from the address information of the adjoining groove. Accordingly, an optical disk is provided, which has a larger capacity, which has high reliability, and which is excellent in durability with respect to repeated writing of data information.
