摘要:
A magnetostatic wave device includes a Gd3Ga5O12 substrate off-angled from a {110} plane. A magnetic thin film including a crystal of garnet is formed on the Gd3Ga5O12 substrate by liquid-phase epitaxy. A transducer operates for exciting magnetostatic wave in the magnetic thin film in response to an RF electric signal. A bias magnetic field is applied to the magnetic thin film. There is a relation as 20°≦|&thgr;1+&thgr;2|≦35°, where “&thgr;1” denotes an angle between a longitudinal direction of the transducer and a orientation of the crystal in the magnetic thin film, and “&thgr;2” denotes an angle between a transverse direction of the transducer and a specified direction. The specified direction is parallel to a line of intersection between a horizontal plane of the magnetic thin film and a given plane which is perpendicular to the horizontal plane of the magnetic thin film and which contains a direction of the bias magnetic field. Also, there is a relation as |&thgr;3|≦75°, where “&thgr;3” denotes an angle between the specified direction and the direction of the bias magnetic field.

摘要:
A polarization-independent optical isolator includes a first birefringent wedge plate having an inclined plane directed to a light incoming side; a second birefringent wedge plate having an inclined plane directed to a light outgoing side, the wedge equal thickness line of the inclined plane of the second birefringent wedge plate being in parallel to the wedge equal thickness line of the inclined plane of the first birefringent wedge plate; and a Faraday rotator element disposed between the first and second birefringent wedge plates. A non-inclined plane of the first birefringent wedge plate is adhesively bonded to a light incoming plane of the Faraday rotator element, and a light outgoing plane of the Faraday rotator element is adhesively bonded to a non-inclined plane of the second birefringent wedge plate. The first and second birefringent wedge plates and the Faraday rotator element thus adhesively bonded to each other are disposed in a cylindrical magnet.
摘要:
The present invention discloses a high-pressure vessel of large size formed with a limited size of e.g. Ni—Cr based precipitation hardenable superalloy. The vessel may have multiple zones.For instance, the high-pressure vessel may be divided into at least three regions with flow-restricting devices and the crystallization region is set higher temperature than other regions. This structure helps to reliably seal both ends of the high-pressure vessel, and at the same time, may help to greatly reduce unfavorable precipitation of group III nitride at the bottom of the vessel.This invention also discloses novel procedures to grow crystals with improved purity, transparency and structural quality. Alkali metal-containing mineralizers are charged with minimum exposure to oxygen and moisture until the high-pressure vessel is filled with ammonia. Several methods to reduce oxygen contamination during the process steps are presented. Also, back etching of seed crystals and a new temperature ramping scheme to improve structural quality are disclosed.

A lead frame for a semiconductor device includes a sheet-like body and a Pd coating plated on the sheet-like body. The Pd coating includes Ni in an amount of not more than 2%. In another embodiment, the Pd coating includes Cu in an amount of not more than 0.12%. By virtue of limiting the amount of Ni or Cu to these particular levels, the solderability of the lead frame is remarkably enhanced.
