摘要:
A box load interface implemented in a FIMS system includes a translation mechanism that actuates a port door attachable to the box door of a transport box to move the box door toward or away from the transport box to open or close it. A clamping mechanism clamps the transport box on a slidable tray controlled to move the transport box against and away from a port plate. An elevator assembly cooperates with the translation mechanism to move the port door after the box door has moved away from the transport box. The translation mechanism and elevator assembly may be integral. A differential optical scanning assembly detects positions of wafer specimens located in the transport box. A robot assembly removes and inserts wafer specimens from the transport box. A linear traveling assembly supports the robot assembly and travels along a lead screw driven by a lead nut mechanism.

A luminescent assembly with an increased brightness has a housing (20), at least one shortwave light source (10), at least one shortwave light cover (30) and a primary visible light source (40). The shortwave light source (10) is mounted with the housing (20) and emits shortwave light when electricity is applied to the shortwave light source (10).The shortwave light cover (30) covers part of the shortwave light source (10). The primary visible light source (40) is significantly larger than the shortwave light source, is a fluorescent/phosphorescent coating, is formed on part of the housing (20), is opposite to the shortwave light cover (30), emits visible light when shortwave light is irradiated from the shortwave light source (10) and reflected by the shortwave light cover (30). Visible light emitted from the primary visible light source (40) passes around the shortwave light source (10) so the luminescent assembly has increased brightness.
摘要:
An illumination unit is described having a light source (24), in particular a high-intensity discharge lamp or an ultra high performance lamp, a main reflector (1) and a back reflector (3) with an aperture opposite the main reflector, through which aperture light is reflected from the light source onto the main reflector. The illumination unit is in particular characterized in that the center of the light source (24) and the back reflector (3) are located or shaped relative to each other such that a first sector angle (L2-L2') enclosed between the light source center and the edge of the back reflector (3) aperture is smaller than 180°. The efficiency of light emission can be considerably increased thereby. Preferred embodiments of the invention relate to various shapes of the back reflector (3) and the inner walls of the gas discharge space, as well as the shape of the part of the glass bulb that surrounds the gas discharge space, where each of these can cause a further increase in light output.

There is provided a fluorescent lamp (10) comprising a glass tube (1) filled therein with an electric discharging medium, a protective film (4) formed on an inner surface of the glass tube, a phosphor layer (5) formed on an upper surface of the protective film, and electrode means (3) attached to the glass tube. The protective film comprises, as a major component, SiO 2 fine particles exhibiting not more than 0.3 at a temperature of 600°C in integrated value of absorbance spectrum of hydroxyl group absorption band in wave number ranging from 2500-3800 cm -1 as measured by infrared spectroscopy on the assumption that the integrated value of absorbance spectrum of hydroxyl group absorption band at a temperature of 100°C is 1. Alternatively, the SiO 2 fine particles contain carbon at a content confined within the range of 0.09% to 0.3% by mass. Alternatively, the SiO 2 fine particles exhibit a spectrum having peaks at a wave number ranging from 590 to 610 cm -1 and at a wave number ranging from 490 to 500 cm -1 as measured by laser Raman spectroscopy and at a temperature of 700°C.

The invention relates to an illumination device comprising a light-emitting tube having a pair of electrodes and a reflecting mirror for reflecting the light from said light-emitting tube toward an illumination region. Said reflecting mirror has an inner surface and an outer surface and said inner surface is inclined at an angle θ with respect to an ideal inner surface, said ideal inner surface reflects the light from an arc image generated between the pair of electrodes so that the reflected light passes through the arc image. Furthermore, a reflecting film of the reflecting mirror is provided on an outer surface of said reflecting mirror.
摘要:
In an outside electrode discharge lamp (11) having dielectric barrier discharge type electrodes (30, 40) on the outer surface of the end portions of a tubular glass vessel (20), the inner wall surface of the tubular glass vessel in at least the electrode disposition areas is covered by protective layers (70, 90), such as metal oxide layers, in such a manner that it is not exposed to the inner space of the vessel (20). This provides an outside electrode discharge lamp that is capable of preventing the tubular glass vessel from being holed at particular locations, thus increasing the service life.

摘要:
A germicidal quartz lamp (10; 110; 210) producing ultraviolet radiation having a sleeve coated (20; 120; 220) with a titanium dioxide (18; 118A, 118B; 218). Titanium dioxide (18; 118A, 118B; 218) is impregnated or embedded into the sleeve (20; 120; 220) and mechanically held. Ultraviolet radiation having a wavelength of approximately 254 nm generated by the germicidal quartz lamp causes hydroxyl radicals to form on the titanium dioxide surface 18; 118A, 118B; 218). The hydroxyl radicals act as a powerful oxidizing agent that destroys pollutants. In one embodiment, different densities of the titanium dioxide (118A, 118B) coating are formed along the longitudinal length of the quartz lamp. A longitudinal portion (118C) of the quartz lamp may be free of any titanium dioxide coating permitting the ultraviolet radiation to pass therethrough creating a germicidal effect. The titanium dioxide may be heated to a temperature above the melting point of the sleeve to create the mechanical bond. The present invention is useful in the commercial food industry or for consumer use.
