  • Patent number: 6659738
    Abstract: A dynamotor capable of operating as either a motor or a generator is used with both the armature portion and the field portion thereof capable of being rotated. In the case where a pulley operatively interlocked with the output shaft of the prime mover is mounted on the rotary shaft of the armature portion, the drive shaft of the compressor is mounted on the rotating field portion. Once the dynamotor is operated in motor mode, the rotational speed of the compressor is increased to the sum of the input rotational speed and the rotational speed of the dynamotor. The compressor is stopped by disconnecting a power feed circuit. When the input rotational speed is too high, the dynamotor is operated in generator mode. In this way, the rotational speed is reduced in accordance with the generated electric energy.

  • Patent number: 6616086
    Abstract: A rotary beam has mounted thereon a pair of carrier arms for rotatably supporting a roll of web from which the web is fed into the press, and another such arm pair for supporting another such web roll to which the web is to be spliced upon consumption of the first web roll. One of each pair of carrier arms has rotatably mounted thereto a hollow spindle to be partly inserted in the tubular core of the web roll. The hollow spindle has detents arranged at circumferential spacings thereon for fluid pressure actuation into frictional engagement with the inside surface of the web roll core. The other of each carrier arm pair has a second spindle rotatably mounted thereto which is to be held endwise against the web roll core via a spring-loaded end cap. How hard the web roll core is urged against the first spindle by the second spindle, resisting the unwinding of the web therefrom, depends upon whether the second spindle is held fast against the end cap or spaced therefrom by the spring.

  • Patent number: 6611094
    Abstract: A simple and slim double-faced vacuum fluorescent display device has no grid, thereby lowing the power consumption and fabrication cost thereof. Anode electrodes on one of the front plate and the back plate function as grids for anode electrodes on the other one of the front plate and the back plate. The light emitted from anode electrodes is not blocked by grids, thereby enhancing light emitting efficiency thereof.

  • Publication number: 20030126970
    Abstract: In order to resolve problems where impact force when a pushing member of a splicing device collides becomes large, strength becomes inconsistent as a result of a pushing force due to reactive force, and paper splicing becomes unstable due to it taking time to suppress this, with paper splicing precision falling as a result, a paper splicing device is provided with a pressing member for pressing running paper web taken from one paper roll against the peripheral surface of a paper roll rotatably driven in such a manner that the peripheral surface moves at substantially the same speed as the speed of running of the paper web.

  • Publication number: 20030093709
    Abstract: The system for supporting network troubleshooting of the invention includes: storage means for periodically storing setting/configuration data and performance data of devices constituting the network based upon a schema of device IDs, interface IDs, and a respective CONFIG version number; monitoring means for monitoring the performance data of the devices by comparing the performance data with respective threshold values; identifying means for identifying the faulty device based upon the schema, when the performance data of at least one device goes beyond a respective threshold value (“faulty device”), wherein the storage means further stores the identified result for network troubleshooting. Thus, the system can estimate a factor of a change of operating condition of the network system and repair accordingly.

  • Publication number: 20030068232
    Abstract: A controlled compressor apparatus enables a hybrid compressor in an idle-stopping vehicle to operate more efficiently when driven by a motor alone. The controlled compressor apparatus includes a compressor 110, included in a refrigeration circuit 200, of a variable volume type for compressing a refrigerant; a motor 120 powered by a battery 12 to operate; and a controller 130 for selecting the driving force provided either by the engine 10 or the motor 120 to drive the compressor 110 and control its discharge volume. The controller 130 causes the motor 120 to operate the compressor 110 such that the compressor 110 is turned on or off at a discharge volume of the compressor 110 that larger within a variable range than that required for operating the refrigeration circuit 200.

  • Patent number: 6522062
    Abstract: A fluorescent display device of the plane grid type capable of reducing accumulation of charges on an insulating layer, to thereby prevent an electron shading phenomenon and permit electrons emitted from a filament toward anode electrodes to be uniformly spread in a plane-like manner on both sides of the filament. A first substrate is formed thereon with stripe-like thin-film anode electrodes and stripe-like thin-film grids in a matrix-like manner through a thin-film insulating layer. The insulating layer and grids are formed with openings. Phosphors are deposited on portions of the anode electrodes exposed through the openings. The grids are formed into a height equal to or smaller than that of the phosphors. A second substrate is formed thereon with back electrodes for controlling emission of electrons from filaments.

  • Patent number: 6509693
    Abstract: A filament core wire capable of being mounted while having tension at a predetermined level applied thereto without an expensive anchor and without applying unnecessary tension thereto. The filament core wire is provided at a part thereof with spring and welded sections. The sections each are covered with a heat-decomposable block element made of acrylic resin or the like. Also, the core wire has a carbonate deposited thereon. The core wire is mounted on a mounting position by removing the block element from the welded section of the wire arranged on the fixing position by heating and then welding the welded section to a fixing spot of the fixing position. Then, block element is removed from the spring section by heating. This permits the filament core wire to be stretchedly arranged at the mounting position while keeping tension applied to the core wire to provide it with elasticity.

  • Publication number: 20030006703
    Abstract: A fluorescent luminous tube is provided that has a getter mirror film formed in an arbitrary shape by illuminating a laser beam onto a getter. In order to form the getter film 32, the rectangular ring-less getter 31 mounted on the anode substrate 11 is irradiated with the laser beam L from the outside of the front substrate 12 and thus is evaporated. In this process, when the illumination spot of the laser beam L is moved along the scanning line 33, the rectangular getter mirror film 32 is formed around the scanning line 33. The burnt region 34, which has the same shape and size as those of the scanning line 33, is formed using the laser beam L.

  • Patent number: 6472064
    Abstract: A tab for fixing a paper web end portion of a paper roll includes a substantially parallelogram-shaped base sheet having two diagonally opposite acute angles. A plurality of linear, discontinuous cuts are formed on the base sheet in parallel with two opposite sides of the base sheet to thereby define a first portion in cooperation with one of the two opposite sides and a second portion in cooperation with the other side. The cuts extend to at least one of other two opposite sides of the base sheet. Adhesive is applied to the first and second portions on the same surface such that an appropriate nonadhesive portion is formed between adhesive applied onto the first portion and adhesive applied onto the second portion. A release sheet having a size greater than that of the tab is attached to an adhesive-applied side of the tab such that a portion thereof is projected beyond the profile of the tab. Alternatively, the release sheet assumes the form of tape.
