摘要:
To provide a thin wideband antenna unit capable of shrinking the size of a radiation element in a case where a dielectric is not used.In a wideband antenna unit 10 having a ground plate 12 and a flat shaped radiation element 14 disposed on a plane (x, y) flush with a plane where the ground plate extends, the radiation element 14 has an elliptically shape. The radiation element 14 and the ground plate 12 are apart from each other by a predetermined feeding distance ΔFD. A ratio between an outside diameter 2aout in an ellipse's x-direction and an outside diameter 2bout in an ellipse's y-direction is 8:5. The elliptically shaped radiation element 14 has an elliptically shaped opening 14a which is concentric O with the elliptically shape. An inside diameter 2bin in the ellipse's y-direction is half of an outside diameter 2bout in the ellipse's y-direction. It is desirable that an inside diameter 2ain of the elliptically shaped opening 14a in the ellipse's x-direction is not more than half of the outside diameter 2aout in the ellipse's x-direction.

摘要:
A method for decreasing the concentration of a chlorinated aromatic compound in the exhaust gas from a combustion furnace. The exhaust gas from the combustion furnace is passed through a bag filter. The concentration of the chlorinated aromatic compound in the exhaust gas is measured and the operating temperature of the bag filter is adjusted based on the measured concentration of the chlorinated aromatic compound in order to decrease the concentration of the chlorinated aromatic compound in the exhaust gas.

An incineration apparatus which can suppress the generation of dioxins, including a combustion furnace (11) for burning a combustible in combustion air within the furnace, chlorinated aromatic compound measuring device (12) for measuring an amount of a chlorinated aromatic compound generated in the combustion furnace, and control device (14, 15, 16) for monitoring the amount of the chlorinated aromatic compound generated, obtained by the measuring device (12), and varying operating conditions of the combustion furnace (11) on the basis of the monitored result, such as to decrease the amount of the chlorinated aromatic compound generated in the combustion furnace (11).
摘要:
The present invention involves a microelectronic device capable of audio playback of highlights, in conjunction with products such as a gift box or a "base" for nostalgia and memorabilia such as a gift or music box (20) with its base (22) and hingedly attached lid (24), or a base supporting an object of interest. A switch (26) or light sensor or other actuation device is mounted in or on the base and is coupled to a circuit board (28) also disposed in the base. The switch is open and the circuit is inactive when lid (24) rests atop base (22), but the switch closes when the lid is opened to activate the circuit board. In the alternative a manual switch, such as a press-button switch, may be used to activate the replay function. The circuit board, when activated, audibly reproduces "highlights", which is audio information sufficiently long to cover a significant event, e.g., a portion of a political speech, a play from a sporting event, a climatic point of a drama or movie, or a broadcast news event yet short enough not to take an inordinate amount of time from the present. Further, the "highlights" should be able to be played in a multiple, consecutive or semi-random order. A ROM chip (30) digitally stores a plurality of highlights which are retrieved and audibly reproduced by a processor (34) on the circuit board when actuated by the switch. The circuit board may be disposed in a gift, music or keepsake box, sports and entertainment memorabilia, cards, frames, statuettes, bases, clocks, and similar items.
摘要:
Boron-substituted graphite, which contains N-bonded boron atoms in a small proportion relative to whole substituted boron atoms, is produced by heating a feed fine particulate mixture of an infusibilized carbonaceous material and a boron compound such that the carbonaceous material is carbonized into a carbon structure, raising a temperature of the resulting heated fine particulate mixture promptly to a graphitization treatment temperature in an inert atmosphere unreactive with boron, retaining the graphitization treatment temperature for a time sufficient to allow graphitization of the carbon structure to proceed to a desired extent, and then quickly cooling the resulting graphitized mixture. The boron-substituted graphite is useful as a negative electrode in a lithium-ion secondary battery.
摘要:
A multiserver workflow system in which each server and the users who use clients construct one subsystem includes: a plurality of servers; a plurality of clients; and a network to which the servers and the clients are connected. All of the servers have address information of the servers constructing all of the subsystems and correspondence information on all of the users and the subsystem which can be used by respective users. When each client connects to any one of the servers, the client downloads a list of the subsystems which can be used by the user who uses the client and addresses of the servers constructing the usable subsystems from the connection server and stores the list as a connectable server list.

A laminated steel sheet for cans comprises: a steel sheet; a metallic chromium plated layer with a 5 to 150 mg/m.sup.2 coating weight formed on the sheet; a hydrated chromium oxide layer with a 3 to 15 mg/m.sup.2 coating weight in terms of chromium formed on the metallic chromium layer; a bonding layer formed on the hydrated chromium oxide layer; and a biaxially oriented polyethylene terephthalate resin film formed on the bonding layer with a strip-shaped margin left for welding, the bonding layer being obtained by curing an adhesive having bisphenol A epoxy resin which has 15,000 to 30,000 number average molecular weight and is from 70 to 90 wt. % of said bonding layer with the remainder being resol phenol resin which has a base of bisphenol A. Other related laminated sheets are also provided.
