Abstract: An atomic oven includes a cartridge and a main body. The cartridge includes a holder that accommodates an atom source; and a capillary nozzle. The main body includes: a housing in which the cartridge is installed; a button heater; an access opening for removing the cartridge from the main body and placing the cartridge into the main body, the access opening being provided on the atmosphere side, which is outside the main body; and a passage from the access opening to the housing. The cartridge is inserted into the main body through the access opening and is installed in the housing. The atom source is heated by the button heater, whereby atomic gas generated from the atom source is emitted as an atom beam to the vacuum side, which is outside the main body.

Abstract: By heating a high-temperature bath with a heater, atomic gas is generated in the high-temperature bath from an atomic source. A magneto-optical trap is realized by a laser beam reflected by a right-angled conical mirror and a magnetic field formed by a magnetic field generator, and the atomic gas is confined by using the magneto-optical trap and cooled. The cooled atoms are output from an opening to the outside of a slow atom beam generator by a laser beam, which is a push laser beam. A slow atomic beam is thereby formed.

Abstract: There is a need to maintain or enhance the magnetic field correction accuracy of a physics package while making the physics package more compact and portable. A triaxial magnetic field correction coil is provided inside a vacuum chamber surrounding a clock transition space having atoms disposed therein. The triaxial magnetic field correction coil is formed into a shape such that it is possible to correct, for magnetic field components of three axial directions passing through the clock transition space, a constant term, a first order spatial derivative term, a second order spatial derivative term, a third or higher order spatial derivative term, or some given combination of these terms. The triaxial magnetic field correction coil can be used in, for example, a physics package for an optical lattice clock.

Abstract: A heat treatment apparatus includes a support sheet placed on an upper surface of a heat-treating plate. The support sheet has, formed on an upper surface thereof, projections for contacting and supporting a substrate, and a lip for contacting edge regions of the substrate. The support sheet is formed by an etching process, and therefore areas of the sheet around the projections are recessed, rather than being perforated as in the case of laser processing. These heat-treating plate and support sheet constitute a substrate support structure capable of supporting the substrate properly.

Abstract: A ventilation fan and light (10) is disclosed having a housing (12) and a light kit (13). The housing includes a housing box (15) with a conventional fan scroll (17) having an electric fan (16) mounted therein. The housing also includes a ceiling plate (21) configured to cover the housing box from view. The ceiling plate includes a decorative features (22) and an array of air intake ports (23) extend through the ceiling plate and positioned within a decorative feature to camouflage the air intake port from view. The light kit includes a plurality of light arms (26) which terminate with a light housing (27) and diffusor (28). The spacial relationship between the ceiling plate and the majority of the light kit structure further obscures the air intake ports from view, prevents the build up of heat within the housing, and creates a better airflow pattern within the room in which the light is mounted.

Abstract: A ceiling fan (10) is disclosed having a motor (13) and motor housing (11) suspended from a ceiling by a downrod (12). The motor rotatably drives an annular array of blades (15). The ceiling fan also includes a tubular screen or shroud (20) mounted about the motor housing and blades so as to substantially conceal a large portion of these components from view. The shroud includes an annular lower mounting plate (21) and an annular side wall (23) extending upwardly from the lower plate. The side wall is formed of a series of candles (24) having the appearance of flickering wicks (25) through incandescent bulbs. The lower plate is coupled to the downrod through a coupler (27) and a series of first arms (28).

Abstract: 7?-Hydroxy-pregn-4-en-3-one-20-carbaldehyde, a production method thereof and a method for producing 7?,21 -dihydroxy-20-methyl-pregn-4-en-3-one, which is useful as a synthetic intermediate for pharmaceuticals such as squalamine and the like, efficiently at high purity from the carbaldehyde.

Abstract: A support table holds a working fluid in an inner space thereof, and has four cylindrical heaters arranged to surround a cooling plate disposed centrally of the support table. In time of heating, vapor generated from each cylindrical heater spreads toward a central region and peripheral regions of the support table (as schematically shown in two-dot chain line arrows). The vapor can reach peripheral ends, without flows of the vapor colliding with one another, in a way to suppress generation of stagnation points. Since the support table can be heated uniformly, a substrate is heat-treated uniformly over the entire surface thereof. The support table is cooled efficiently by the cooling plate disposed centrally of the support table.

Abstract: A weathering test method comprising making active oxygen and light simultaneously act on a test piece, a weathering test method comprising successive and/or alternate steps of making active oxygen and light simultaneously act on a test piece and making at least one of light, oxygen, and water to act on the test piece, and apparatus for carrying out the methods are disclosed. In evaluating weatherability of organic materials, articles made of organic materials or articles coated with organic materials, the methods and apparatus achieve acceleration of deterioration of test pieces to greatly reduce the testing time.
