  • Radio base station device and radio communication method
    Publication number: 20020137546
    Abstract: The replica signals generated in a replica generation circuit 306 are sent to a combining circuit 203 through a bus 204. In the combining circuit 203, the above replica signals are input from each circuit board X through Z for combining of replica signals. In a channel allocation control circuit 202, a new channel is allocated so that the relations between the order and likelihood are almost uniform among subsets, based on likelihood information reported from each circuit board X through Z which is a subset; accommodated symbol rates and services (voice signals and packet signals); target SIRs and so on. Thereafter, the allocation control signals are sent to each circuit board X through Z.

  • Substrate processing apparatus and substrate processing method
    Publication number: 20020134512
    Abstract: A support member of a rotary base member engages with a substrate for preventing the substrate from horizontal movement and rotation with respect to the rotary base member while allowing vertical movement of the substrate, and a proximity suction plate is provided above the rotary base member so that the lower surface thereof is formed on a plane on the rotary base member parallel to the substrate for downwardly and outwardly injecting gas toward the overall upper surface of the substrate and sucking the substrate in a proximity state by Bernoulli effect. It is possible to provide an apparatus capable of reliably preventing mist of a processing solution or the processing solution from reaching the upper surface of the substrate when rotating the substrate and supplying the processing solution to the lower surface for processing the substrate.

    Publication number: 20020137548
    Abstract: Weights are not calculated by using signals of the preamble section in a random access channel (RACH), but signals of the preamble section of the RACH are received by an adaptive array antenna (AAA) with a plurality of directivity patterns using the existing weights, delay profiles are prepared for respective directivity patterns, and the preamble section and despreading timing are detected by using the delay profiles. Further, the invention is featured in that a control signal in an acquisition indication channel (AICH) is received by the AAA with a directivity pattern that is selected when receiving the signals of preamble section of the RACH by the AAA.

  • Guide bush and method of forming hard carbon film over the inner surface of the guide bush
    Patent number: 6419997
    Abstract: A hard carbon film (15) is formed directly or through an intermediate layer for enhancing adhesion over an inner surface (11b) of a guide bush (11) for holding a workpiece (51) rotatably and axially slidable on an automatic lathe at a position near a cutting tool, to be in sliding contact with the workpiece (51) or directly or through an intermediate layer for enhancing adhesion on the surface of a superhard lining fixed to the inner surface (11b). The guide bush (11) has remarkably enhanced durability and prevents damaging the workpiece (51) and seizing that makes a machining operation impossible even when the guide bush (11) is used for an extended period of time and when the automatic lathe operates for heavy machining.

  • Radio communication apparatus
    Patent number: 6404778
    Abstract: In a mobile station apparatus and a base station apparatus in a digital mobile communication using a TDD system and a CDMA system, in the case where there is a difference in communication qualities between a revere link and a forward Link, a burst length of a communication link with lower quality can be made longer than a burst length of a communication link with higher quality. That makes it possible to communicate more signals in the communication link with low communication quality than in the communication link with high communication quality, which allows the equal communication qualities in the reverse link and the forward link.

  • CDMA cellular radio transmission system
    Patent number: 6400700
    Abstract: A base station transmits, in addition to a pilot channel, signals which are multiplexed with pilot symbols inserted in the respective signals in communication channels. As the transmission of the pilot channel as a reference signal for coherent detection is unnecessary with high power so as to attain high reliability, the pilot channel can be transmitted with low power by means of weight in comparison with the communication channel, so that interference with the communication channel of any other station is reduced. Moreover, accurate coherent detection can be made from the pilot symbol inserted in the communication channel on the mobile station side.

  • Method of enhancing transfer printing quality
    Patent number: 6386698
    Abstract: A method of transfer printing for increasing the reproducibility in achieving high-precision, high-brilliance transfer prints by controlling the print density of yellow sublimate ink on the transfer material within a specified range of yellow density. The invention has application in transfer printing methods where a digitized image is produced on a transfer material by printing the image from a PC by a ink jet printer using sublimate ink. The printed image on the transfer material is transferred to a print medium by heat processing. The other colors of the image are adjusted based upon the print density of yellow sublimate ink falling within the specified range.

  • CDMA radio multiplex transmitting device and a CDMA radio multiplex receiving device
    Patent number: 6370131
    Abstract: In the CDMA Radio Multiplex Transmission, transfer function of line is inferred by using common pilot signal and synchronous detection is performed accordingly. The transmitting end transmits by periodically inserting pilot symbols into one channel only of multiplexed channels. The receiving end infers line condition (transfer function) from the received pilot symbols and, on the basis of the information thus obtained, performs synchronous detection of each channel multiplexed.
