  • Publication number: 20030055889
    Abstract: A method of transmitting update-display data (1) from a thin server device to a thin client device, the method comprising the steps of: generating a (short) key representing new update-display data (1) to be transmitted; comparing a newly generated key to a key or keys previously generated; compiling a message to be transmitted to the client device; the message comprising a header and code words representing the update-display data, wherein the header is set in dependence upon the result of the comparison step to identify to the client whether the update-display data is already cached, to be cached or not to be cached.

  • Publication number: 20020178561
    Abstract: A pipe sealing structure for forming a thermal pipe is formed by steps of performing a reduced cross sectional area less than the cross sectional area of the opening thereof to form an extended region, clamping a portion of the extruded region into a collapsed portion, cutting the outer end of the collapsed portion, and peforming a spot welding on the cut outer end of the collapsed portion. Furthermore, additional steps including selectively determining a predetermined length of the thermal pipe, forming a reduced size portion of the pipe at the predetermined length are added to the manufacturing procedure.

  • Patent number: 6446709
    Abstract: The present invention provides a combination heat radiator, which is a plate body formed by cutting thermal conductive material like aluminum, copper, or graphite. A plurality of spaced openings are formed by punching one side of the plate body. A connection portion is disposed on the other side of the plate body. Remaining materials of the openings are bent upwards to form a plurality of heat-radiating fins. The openings of the plate body are staggered with openings of another plate body to facilitate engagement of the two plate bodies. Complete heat-radiating fins are thus formed. The size of the connection portion can be enlarged to be directly placed on different heat-emitting devices for use. The connection portion can be bent to match the shape of a heat-radiating device, thereby enhancing practicability of the heat-radiating fins. Moreover, the production cost can be effectively reduced, and heat-radiating efficiency can be greatly enhanced.

  • Patent number: 6421239
    Abstract: An integral heat dissipating device includes a radiating plate, a fan blade and a cover. The radiating plate has a heat dissipating channel. A fan blade receiving chamber is communicated with the heat dissipating channel and a heat conductive plate is connected to the bottom of the outer wall of the heat dissipating channel. The bottom of the fan blade receiving chamber is installed with an axial hole which serves to be installed with a fan blade. The axial hole can be installed with a fan blade with power. An inclined surface is formed at the upper side of the fan blade receiving chamber. A plate shape heat tube is welded between the heat conductive plate and the bottom of the heat dissipating channel. A plurality of screw retaining posts capable of being screwedly fixed to a circuit board being suspended from the lateral side of the heat conductive plate. The cover is a thin plate with a hole for sealing the upper side of the heat dissipating channel and the fan blade receiving chamber.

  • Publication number: 20020038268
    Abstract: A financial cost prediction system method, wherein the subserver of each department is connected to the main server, and the initial cost data of each department is screened and classified via the main server to form financial reports. The financial reports and further organized into a standard cost account, and are provided to the finance department user terminal for to access the financial reports and to compare to the standard cost account. Also, the present system enables the initial cost data to automatically compile into financial reports and sets the schedules of the main server, so as to automatically correct erroneous financial reports. By using this system, to predict the cost and expense for the coming month or the coming year can be obtained.

  • Patent number: 6340056
    Abstract: A flow channel type heat dissipating fin set is formed by a plurality of metal pieces. Each metal piece comprises a body; and a connecting piece installed on the body having one or more connecting pieces punched from the body; the connecting piece being protruded from one side of the body; a via hole being formed on the body; and buckles and buckling holes being formed on the body. The metal pieces are combined by buckling the buckles and buckling holes so that the metal pieces are continuously buckled and stacked as a heat dissipating fin set; and via holes on the bodies of the metal pieces are formed as longitudinal flow channels. Thus, a flow channel type heat dissipating fin set is formed.

  • Publication number: 20010032287
    Abstract: A processing method, a chip set and a controller for supporting message signaled interrupt. A memory write transaction on a PCI bus is monitored. When the address of the system memory specified in the interrupt message of the write transaction is located at a range of a reserved interrupt address, the interrupting service sequence is performed. The reserved interrupt address is located in an address of a system memory. Thus, the data to be processed and the system-specified message are written in the buffer and arranged in sequence. The problem of “write buffer latency” is resolved, and is irrelevant to the level of the PCI bus. Many system specified messages can be stored in the system memory, so that multiple system message signaled interrupts issue from different peripheral components can be processed in the same interrupt service routine.

  • Patent number: 4956598
    Abstract: Prior variable speed constant frequency (VSCF) generating systems which utilize an inverter to derive constant frequency power from variable frequency power developed by a generator driven by a prime mover have controlled system output voltage by controlling the excitation of the generator. Such a control technique, however, does not provide voltage regulation of individual phases and minimize undesirable distortion in the system output. In order to overcome the foregoing problem, a control for a VSCF system having a generator and an inverter which receives DC power from a rectifier coupled to the generator controls switches in the inverter to maintain the voltage of the AC power developed by the inverter at a desired level and controls the power applied to an exciter of the generator to maintain the voltage of the DC power at a particular level relative to the voltage of the AC power developed thereby. Distortion in the inverter output is thereby minimized.

  • Patent number: 4914988
    Abstract: The present disclosure is concerned with an electrically rechargeable eyebrow tattooing machine which is particularly employed by female to do make-up on the eyebrow as a result of the lack of hair thereat. A small motor drives an eccentric cam which is further connected with a drive rod with an elongate needle detachably disposed at the front end thereof, and the motion of the eccentric cam produces a reciprocating movement on the elongate needle which is received in a casing with its pointy tip retractably sticking out of a small bore of a frontmost cap. The cap is provided with an opening on the wall so that cotton with dye liquid can be stuffed therein, and each time the needle can acquire small amount of dye liquid in its repeated motion through the dye contained cotton. The use of rechargeable source makes the operation of the present machine with less vibration and the small size facilitates the safe holding of the same in operation.
