The disclosed subject matter includes a fluorescent lamp and particularly a cold cathode fluorescent lamp that can be employed as a light source for a LCD backlight unit for a television, a computer, a display, and the like. The fluorescent lamp can include a couple of electrode units located opposite to each other at each end of a tube, a couple of welding beads sealing both the tube and the couple of electrode units, and a filler gas located in the tube. Each of the electrode units can include an emitter electrode that is configured with a crystalline silicon semiconductor material having an electrical conductivity or configured with other semiconductor materials, and can include a concave portion formed thereon. The electrode units can prevent blackening on an inner surface of the tube by avoiding the occurrence of spattering. Thus, the fluorescent lamp using the electrode units can enjoy a long life, high reliability, easy manufacture, and the like.

Fluorescent lamp

A method for manufacturing a hot cathode fluorescent lamp can ensure or facilitate stable initial luminous intensity and provide improved product life characteristics even when the hot cathode fluorescent lamp employs a glass tube with an outer diameter of less than 7 mm&#x3c6;. One end of a glass tube can be sealed with a glass bead of a mount structure. The other opening end of the glass tube can be welded with an opening end of an exhaust pipe with bent portions of lead wires being sandwiched between the opening ends of the glass tube and the exhaust pipe. After evacuating a vacuum system that is constituted by the inner spaces of the glass tube and the exhausted pipe communicating with each other, the bent portions of the lead wires which extrude outside the vacuum system can be clamp-connected to power source lines extending from an external power source. The emitter of the filaments can be activated by the generated heat of the filament. After supplying mercury and a rare gas into the glass tube, the glass bead can be sealed, and unnecessary portions of the glass tube, the exhaust pipe, and the lead wires can be removed to complete the hot cathode fluorescent lamp, in accordance with one aspect of the disclosed subject matter.

A template file defines a video material data, a first still picture material data, a second still picture material data and text data, and a display area for each of the material data. A presentation file defines the template file and a correlation between each of the display areas and each material data. Based on the template file and the presentation file, an information display device combines and displays as a program the video material data, the first still picture material data, the second still picture material data, and the text data in their respective display areas.

A voltage-controlled oscillator has a tuned circuit for controlling the oscillation frequency. The tuned circuit has a variable-capacitance element whose capacitance varies in response to a control voltage and a negative capacitance circuit whose impedance frequency characteristics have opposite characteristics to those of a normal capacitance, and which is connected to the variable-capacitance element. The configuration enables increasing the variation ratio corresponding to the control voltage of the combined capacitance composed of the variable-capacitance element and negative capacitance circuit, thereby broadening the oscillation frequency band.

An information delivery and display system includes one or more information display devices that play display information, and a monitoring/control server that sends information to the information display device when the information display device carries out polling at predetermined time intervals. The monitoring/control server includes a control instruction unit that creates control instruction information to change a polling interval of the information display device and that sends the created control instruction information to the information display device when the information display device carries out polling.

Information delivery and display system and information delivery method

The file creating processing unit creates at least one material data and at least one control information file to display the material data in a presentation package storage folder corresponding to a presentation pack. When a package creating processing unit receives a delivery designation, the package creating processing unit creates at least one package from all files in the presentation package storage folder to satisfy a predetermined condition and delivers presentation packs in units of packages to an information display device through a data distribution server.

A data management device in a karaoke system which receives a first data file by a receiving unit and is stored in a rewritable memory such as a hard disk. A second data file, recorded on a recording medium such as a CD-ROM, is read out by a reading unit. A file number comparing unit then compares the file numbers of the first and second data file and a file managing unit erases the first data file if the file numbers coincide with each other. In addition, a version comparing unit compares versions of both the first and second data file. If the first data file version is older than the second data file version, then the file managing unit erases the first data file version, so as to ensure that the new version is always used. Furthermore, a detecting unit detects whether data files corresponding to targeted items are recorded in both, the rewritable memory and the recording medium. In the event that data files are recorded in both, the file managing unit erases the data file in the rewritable memory.
