Abstract:
A work liquid storage apparatus of an electric discharge machine having a work tank (2) for storing a work liquid (5) supplied by work liquid supply (6) with a workpiece (4) placed in the work liquid (5), the work tank having an opening (2a), a door (12) for opening and closing the opening (2a), and a seal member (10) for hermetically sealing space between the work tank (2) and the door (12) includes support plates (13) each being formed with a long hole (13a) in an up and down direction, fixing (14) for fixing the support plates (13) and the door (12), and arms (15) each being rotatably supported at both end parts with the work tank (2) and the support plate (13). Since the door (12) can be held at the position covering the lower end part of the opening (2a) of the work tank (2) and the position exposing the lower end part of the opening (2a), maintenance work and replacement work of the seal member (10) can be performed easily.
Abstract:
A flat visual display device is disclosed herein and includes a flat face plate having a front face and an opposite back face and electrically positive means on the latter which, as a result of the impingement of the electrons thereon, provides a visual image through the front face of the face plate. The device utilizes an arrangement including cathode means for establishing a uniformly dense space-charge cloud of free electrons within a planar band parallel with and rearward of the back face of the display face plate. Means including an apertured address plate disposed in spaced-apart confronting relationship with the back face of the face plate between the latter and the uniform space-charge cloud acts on the electrons within the cloud in a controlled way so as to cause the electrons acted upon to impinge on specific areas of the electrically positive back face plate means of the display face plate in order to produce a desired image through the face plate's front face.
Abstract:
Producing a glass solder seal without interfering thermal stresses in a display device containing at least two mutually parallel plates tightly connected at the edges via a frame. One plate is coated with a pattern of separately addressable electrodes which are each brought to the outsides through the frame. The method includes(a) also covering the electrode pattern in the region provided for the frame,(b) covering the such feedthrough region with a second mask which is later removed, and(c) using a frame made of glass solder.
Abstract:
A perforated glass plate for use in gas discharge display devices is produced by providing an etch-resistant coating in a select pattern on surfaces of a glass plate so that areas to be perforated are coating-free, subjecting the so-coated glass plate to a gaseous hydrofluoric acid, obtained from concentrated hydrofluoric acid, for a period of time sufficient to etch fine sized perforations, for example holes, through the plate and rinsing the etched plates.
Abstract:
The hollow cathode gas discharge device is configured with a maximized cathode-to-anode area ratio to operate in a lowpressure glow discharge mode to generate a plasme of adequate density from which electrons or ions can be extracted and accelerated. This permits the gas pressure to be kept low to avoid Paschen breakdown in the high voltage acceleration region. The invention herein described was made in the course of or under a Contract or subcontract thereunder with the Department of the Navy.
Abstract:
A charge storage device and method of manufacture of the type in which a target electrode provides a plurality of spatially disturbed isolated charge storage sites of semiconductor material provided within the interstices of an electrical conductive mesh with insulating barrier means provided between the semiconductor storage sites and the conductive mesh. Input excitation is directed onto the input side of the target and may be in the form of electrons or light capable of generating electron-hole pairs within the semiconductor material which diffuse through to the storage sites. The storage sites which are located on the output side of the target are provided with sensing and converting means such as an electron beam for converting the charge into an electrical signal. The process of manufacture of the device includes providing a semiconductor wafer with a substrate and pillars extending from one surface of said substrate, forming a junction within the upper portion of the pillar, providing an insulating coating on the pillars and surrounding intervening surfaces between the pillars, electroplating an electrical conductive support mesh within the moat region surrounding the pillars and etching away the substrate of the wafer so that only the pillar members remain supported within the metallic support mesh framework. The conductive mesh with the insulating coating provides a barrier about each semiconductor storage site and permits passage of minority carriers generated near the input side of the target within the semiconductor member to the storage sites without diffusion to adjacent storage sites. In this manner, the target images intense spots of input radiation in a scene without significant spreading or blooming of the high intensity spots caused by lateral diffusion of the minority carriers through adjacent storage sites.
Abstract:
A method and apparatus for changing the states of gaseous discharge cells in a plasma panel including applying a light flash to the cells simultaneously during a discharge of the cells. Transferring an image to the plasma panel by applying a light flash corresponding to the image to the gaseous discharge cells simultaneously during a repetitive sustaining discharge of the cells.
Abstract:
A solution-cathode glow discharge mass spectrometry (SCGD-MS) apparatus comprises a SCGD source and a mass spectrometer. The SCGD source may comprise conductive rods, a power source, and a capillary. A method for ionizing an analyte comprises flowing an electrically conductive liquid onto a conductive rod, applying an electric potential to a second conductive rod such that a plasma discharge forms between the first conductive rod and the electrically conductive liquid to produce ions, and separating the ions in a mass spectrometer. The analyte may be a polypeptide that may be contacted with trypsin. The analyte may be a solid, liquid, gas, chemical complex, or ion in solution. The method may comprise sequencing the polypeptide.
Abstract:
An electrical assembly having a support, a mounting member and an electrical device attached to the mounting member and the support. The mounting member is a one piece integrally formed unit having an interior cavity for receiving electrical wires from the power source and supplying the electrical wires to the electrical device. The mounting member has a coupling at a first end of the mounting member with internal threads having an annular recess receiving a seal member for forming a weatherproof seal with the support while allowing limited rotational adjustment of the mounting member with the support and maintaining the weatherproof seal. The mounting member has a second end with a coupling having external threads complementing the internal threads of the first coupling to enable a plurality of the mounting members to be coupled together and forming a weatherproof connection between the adjacent mounting members.
Abstract:
A TV bridge kit including an assembly of components for mounting a TV to a wall while minimizing disruption to the wall surface. The kit includes a first and second frame member with cover plates and an electrical cable having a male and a female plug end. Frame members include rotatable clamp arms to enable rapid installation to existing walls. Cover plates include openings and peripheral walls adapted to receive nose portions of the plug ends. Tabs on the plug ends of the electrical cable enable connection to bosses in the peripheral walls of the cover plates. An outer flange on the frame members enable recessed mounting of the cover plates with the front surface of the plug ends flush with the cover plate. After installation on a wall, the TV bridge kit is powered by connection of a conventional electrical cord from an existing outlet.
