    摘要: 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.

    摘要: The electrical connector of the present invention has an insulative housing having a first face across from a first electrical circuit and a second face across from a second electrical circuit. A plurality of contacts are mounted in the insulative housing, each of which contacts a contact point of the first electrical circuit at the first face, and contacts a contact point of the second electrical circuit at the second face, thereby interconnecting the first and second circuits. Each of the contacts has one portion of the contact supported by the insulative housing so as to be capable of pivoting in response to the displacement of the first contact portion and the second contact portion.

    摘要: A land grid array socket contact has a resilient contact that extends parallel to a base plate and is attached to at least one side walls of the base plate by a curved section angled approximately 180 degrees from the at least one side wall. The resilient contact has a free end for contacting a contact pad. A board terminal extends from a lower end of the base plate for connection to a circuit board. In another embodiment, the land grid array socket contact has a resilient contact extending from an upper end of a base plate. The resilient contact has an elongated slit substantially in a center of the resilient contact with respect to a direction of width and a free end for contacting a contact pad. A board terminal extends from a lower end of the base plate for connection to a circuit board.

    摘要: The depth and a relative dimensional factor of a defect present in the interior of a silicon wafer are measured, and the number of such defects is calculated. A laser beam having a larger energy than the band gap of silicon is radiated obliquely to the semiconductor wafer and a scattered beam from a defect present in a subsurface layer of the wafer is detected by an image pick-up device. The temperature of the wafer is changed to at least two temperatures of T1 and T2 or to any one of plural temperatures by means of a heater and the intensity of a scattered beam is measured. It is taken into account that the light absorbance of silicon and the penetration depth of light in silicon vary depending on temperature, to determine the depth and a relative dimensional factor of an internal defect which causes scattering of light, as well as the number of such crystal defects.

    摘要: In a measurement method for measuring the epitaxial film thickness of a multilayer epitaxial wafer, a reflectivity spectrum of a multilayer epitaxial wafer having at least two epitaxial layers of different electric characteristics is measured by using infrared radiation in a far infrared region of at least 500 cm.sup.-1 or less, and frequency-analysis is performed on the reflection spectrum thus obtained by a maximum entropy method, and the film thickness of each epitaxial layer is calculated on the basis of the analysis spectrum thus obtained.
