A gas permeable electrode is arranged to project into an evacuated space with the vacuum side of the electrode coated with a gas impervious material except at the tip of the electrode. The other end of the electrode is exposed to an ionizable gas that is caused to diffuse through the electrode and be ionized at the tip of the electrode on the high vacuum side by an electrical field created between the gas permeable electrode and an extraction electrode in the high vacuum space.

Disclosure is made of a compound of the formula: ##STR1## and pharmaceutically acceptable salts thereof. A salt, for instance, the dihydrochloride is usable as a compound which exhibits psychotropic and antiemetic effect.

An illumination apparatus for illumination of light by emitting light from LED for each of RGB colors capable of optionally setting a color temperature and controlling the brightness after the setting while maintaining the color temperature as it is, in which a light control circuit supplies a light control voltage for variably controlling the light quantity of the illumination light equally to each color setting circuit connected with LED of each color which is lit by a light quantity in propor...

A video camera which comprises a progressive scanning CCD, a camera signal processing part for converting an output from the progressive scanning CCD to a video signal adaptive to video display, and a driving means for driving the progressive scanning CCD, and which enables to enlarge dynamic range by synthesizing a first signal obtained by exposure during a first predetermined time and a second signal obtained by exposure during a predetermined time after the exposure time of the first signal b...

Antioxidant additives for lubricating oils are prepared by reacting an acidic molybdenum compound or salt thereof and a basic nitrogen compound where the temperature of the process does not exceed 120.degree. C., resulting in a product color that is light in intensity.

The invention relates to pesticidal composition against bacterial plant diseases comprising as active ingredient a nitrofurane derivative of the general Formula I ##STR1## wherein X represents a group of the Formula a/ ##STR2## and optionally one or more known fungicidal active ingredient/s/ in a total amount of 1-99% by weight, whereby the ratio of the active ingredient of the general Formula I to the known fungicidal active ingredient/s/ amounts to 1:99-99:1, preferably 1:9-9:1 if the composit...

The invention is directed to an ingress/egress system for allowing ingress/egress to and from a fixed structure, such as a pier or dock, and a boat having a superstructure. The ingress/egress system includes a ramp connected to the superstructure, which ramp is movable between a first position and a second position. At least two rigid extension arms are pivotally connected to the superstructure, with each extension arm including a device for connecting to the fixed structure. The extension arms ...

An indoor lighting arrangement employing a combination of high pressure sodium (HPS) light sources, which produce a yellowish light, and mercury vapor or metal halide light sources, which produce a whiter light. Where the distance between the floor and the plane containing the light sources is at least fifteen feet, the HPS and whiter light sources are mounted in a checkerboard pattern so that the yellow and white illumination which they produce is completely mixed at normal eye level. When lowe...

A light source having emissions in a plurality of spectral bands. The simplest light source according to the present invention is constructed from first and second light sources and a dichroic beam splitter. The first and second solid state light sources emit light in first and second bands of non or only partially-overlapping wavelengths. The dichroic beam splitter combines light from the first and second solid state light sources by passing light in the first band while reflecting light in the...

A first embodiment of an illumination source including red LEDs, green LEDs, and blue LEDs provides illumination for a scanner. The LEDs are arranged in an array to generate spectrally and spatially substantially uniform illumination on the surface of an object, such as printed media, which is to be scanned. The arrangement of LEDs includes a plurality of groups of three LEDs. Each group of LEDs includes a red LED, a green LED, and a blue LED. The LEDs of like colors are connected in series. Pow...
