By means of a fluid material discharge device of simple construction, a technique for fluid material discharge is provided which has few or no inadequate discharge, high productivity, and which enables easy modification and adjustment of the amount of fluid material discharge. The fluid material discharge device comprises a nozzle for discharge of fluid material and a filament-shape member inserted into the nozzle for use. The filament-shape member has a tip portion AA, which is exposed outside ...

A discharge electrode for an electrostatic precipitator has a collar having two oppositely disposed arms extending radially therefrom, with each radially extending arm terminating in a number of tines at its free end. Each tine is pointed and is curved relative to a plane of the oppositely disposed radially extending arms. Adjacent tines of a pair of tines at the end of each arm are oppositely curved relative to the plane of the radially extending arms. The discharge electrode preferably is form...

A discharge tube is disclosed that includes: an airtight tube having first and second end surfaces each including a metallized surface; first and second discharge electrodes joined to the respective metallized surfaces; and multiple trigger lines formed on the inner wall surface of the airtight tube to extend along the axial directions of the airtight tube. The first and second discharge electrodes are joined to the metallized surfaces so that a discharge gap is formed between the first and seco...

A port (such as, but not limited to, an RJ45 port) may comprise a cavity having a plurality of pins and an electrostatic discharge element coupled to a system ground. As the plug is inserted into the cavity, the electrostatic discharge element contacts the plug prior to the plug coming into electrical contact with the port pins and provides a discharge path to the system ground during a cable discharge event. Once the plug is fully inserted within the port, the electrostatic discharge element do...

A discharge tube comprises a pair of discharge electrodes opposed to each other with a discharge space in-between, an airtight cylinder in which the discharge space is formed, the pair of the electrodes respectively being mounted on both ends of the airtight cylinder, and a coating film which is resistant to water permeation, and formed on a surface of the airtight cylinder. With the discharge tube, it is possible to perform a stable discharge having a good insulating property between the discha...

The invention provides an advantageous shape of discharge tube and a discharge lamp including such a tube which is particularly beneficial for use in dimensions intended to replace general lighting service lamps but can readily be adapted to other sizes. The discharge tube is shaped to define a substantial part of the boundary of a substantially planar zone. The part of the tube defining the boundary includes at least one straight portion. In one embodiment it defines three sides of a square wit...

In a discharge regulator for outlets from liquid containers, in particular rain runoff retention reservoirs, in which a regulator plate or diaphragm is guided in front of the outlet opening and is operatively connected to a float by means of transmission elements which may at the same time be control elements, the regulator (1) is guided pivotally in front of the outlet opening (2) and is mounted above the latter on a fixed rotation axis (4) jointly with a disk (3) on a base plate (11). A transm...

The invention relates to a single ended discharge lamp, such as a CID or CSI lamp having a bi-pin base. The base is such as to fit a socket suitable for lamps such as tungsten halogen filament lamps for which lower voltages are used and is adapted to make use in such sockets possible. The base or cap member is provided in the usual manner with two pins but at least one of the pins is a dummy pin. At least one extra terminal is disposed to the side of the base whereby electrical connection to one...

Discharge tubes for a lamp include a body portion with a first end, a second end, and a tubular member defining an interior area. The tubular member extends along an elongated axis between the first end and the second end. The discharge tube further includes a first end portion provided at the first end of the body portion. The first end portion includes a first tubular extension having a first through passage in communication with the interior area. The first end portion further includes a firs...

A discharge lamp includes a coaxial waveguide for high-frequency electromagnetic wave transmission and a discharge tube for emitting light of discharge by plasma generated by electromagnetic waves. The coaxial waveguide includes an internal conductor and a pipe-shaped external conductor surrounding the internal conductor. The discharge tube is attached to a top of the coaxial waveguide, and is constructed in a double end shape in which both ends of a glass tube are pinched and sealed. The glass ...
