摘要： It is an object of the present invention to provide an epitaxial wafer with fewer pit defects in the epitaxial layer of a silicon monocrystalline wafer that has been doped with arsenic. Pit defects tend to occur when gas etching is performed prior to epitaxial film formation, but this tendency is reversed and a sound epitaxial layer is obtained by setting the crystal plane orientation to (100) and specifying the range of the tilt angle for the angle θ in the [001] direction or [001] direction or the angle φ in the [010] direction or [010] direction with respect to the [100] axis.

摘要： In an antenna structure in which a base is mounted in a ground region on a circuit board, the base having formed thereon a driven radiating electrode and a parasitic radiating electrode, the parasitic radiating electrode causing multiple resonance at least in a harmonic resonant frequency band of the driven radiating electrode, capacitance loading means for loading a capacitance to a harmonic-mode zero voltage region of the driven radiating electrode is provided. The capacitance loading means is electrically connected to a ground electrode in the ground region on the circuit board via a grounding conduction path and switching means. By switching the switching means ON/OFF, capacitance loading by the capacitance loading means to the harmonic-mode zero voltage region of the driven radiating electrode is switched ON/OFF to switch a base resonant frequency in a base resonant frequency band of the driven radiating electrode.

摘要： A detecting system for detecting a rotation angle of a deflecting mirror is disclosed. The detecting system is provided with a laser diode, an objective lens, and a deflection mirror therebetween. The deflection mirror is rotatable about a predetermined rotation axis to change the position, on an optical disc, at which a laser beam emitted by the laser diode is incident. Further, a beam splitter is provided to split the light beam into a first beam directed to the optical disc via the deflection mirror, and a second beam that is directed to a reflection surface of the deflection mirror. The second beam reflected by the reflection member is not directed to the optical disc but received by a detector which determines the rotation angle of the deflection mirror in accordance with the received second beam.

摘要： This disclosure provides a wideband antenna including a feed line, a ground conductor plate and a radiating conductor element connected to the feed line and facing the ground conductor plate at a distance from the ground conductor plate. A parasitic conductor element is provided on a side opposite to the ground conductor plate as viewed from the radiating conductor plate and is insulated from these plates. A coupling adjusting conductor plate is positioned between the radiating conductor element and the parasitic conductor element, is configured to adjust an amount of coupling between them, overlaps an area where the radiating conductor element and the parasitic conductor element overlap, and straddles the radiating conductor element in a direction orthogonal to the direction of a current I that flows therein. Both end sides of the coupling adjusting conductor plate are electrically connected to the ground conductor plate via via-holes.
