摘要:
A packet communication method of the present invention includes establishing a radio layer 2 connection based on a radio layer 2 protocol between a mobile station and a controller device, determining a transmission timing of a received data packet based on a quality of service set in the data packet, and multiplexing, at the determined transmission timing, the data packet into a radio layer 2 protocol data unit of a fixed length which is transmitted and received on the radio layer 2 connection.

An axial flow turbine stage structure has: an annular diaphragm inner ring; an annular diaphragm outer ring arranged radially outside and coaxially with the diaphragm inner ring and separated from the diaphragm inner ring by an annular flow path interposed between them; stationary blades arranged peripherally at intervals in the annular flow path and rigidly secured to the diaphragm inner ring and the diaphragm outer ring; and moving blades rigidly secured to the outer periphery of a rotatable rotor and arranged peripherally at intervals respectively at axially downstream sides of the stationary blades. Through holes are formed in the diaphragm outer ring so as to allow axial upstream side and axially downstream side of the stationary blades to communicate with each other.

A row of moving blades for a steam turbine has moving blades elongated radially which are arranged peripherally around and secured to a turbine rotor 9. The row also has an intermediate support structure for holding the blades each other at a radially intermediate position. The support structure has a shape of streamline cross section. The support structure may include a tie wire secured to the blades, or lugs protruding from the blades and combined to each other. The support structure may include lugs protruding from the blades to each other, and a sleeve combining the lugs. The shape of streamline cross section may have an obtuse-angle or acute-angle upstream part.

A game machines has a back side display unit composed of reels for displaying back patterns, and a front side display unit composed of transparent EL panels for displaying overlapping patterns overlapping with the back patterns. The back side display unit and the front side display unit are disposed not to produce blind spot regions of the back patterns. The game machine can provide various overlapping patterns with good visibility and a high game selection capability to a player.
摘要:
By using a dephlegmator which conducts distillation concurrently with heat exchange within at least one distillation column, or a portion of one distillation column, of a distillation cascade, the quantity of liquid holdup within the distillation apparatus is reduced and the start-up time is shortened. Consequently, the operational costs associated with startup are reduced, and productivity is improved markedly.

HLR installed in an environment in which there are a plurality of mobile communication networks, is provided with a whole managed object manager for storing and managing subscriber number IDs and HLR information to manage the subscriber number IDs, in correspondence to each other; a subscriber data manager for storing and managing subscriber number IDs registered as managed objects of the host HLR and subscriber data of the subscriber numbers in correspondence to each other; and a determination controller for determining whether subscriber management information (subscriber number IDs and subscriber data) of managed objects in the host HLR is to be transferred to another HLR, based on criterion information such as current subscriber management information volume and accommodation capacity information, and for, when the transfer is necessary, determining a recipient HLR and subscriber management information of a transferred object, based on the criterion information in each HLR and a predetermined standard.
摘要:
A radio data communications method capable of changing control points located in a network without causing loss of data when a mobile terminal is performing a soft handover. In the radio data communications method in which at least one of a first radio network controller and a second radio network controller performs a soft handover process for allowing a soft handover of a mobile terminal when the mobile terminal is performing soft handover, in downlink radio data communications in which the first radio network controller transmits data to a mobile terminal via a second radio network controller and a base station (or in uplink radio data communications). The first radio network controller or the second radio network controller performing the soft handover process is changed when the mobile terminal is performing the soft handover.
摘要:
A base station including a transmitting and receiving amplifier for amplifying CDMA signals exchanged with a mobile station; a radio stage connected to the transmitting and receiving amplifier for carrying out D/A conversion of a transmitted signal that undergoes baseband spreading, followed by quadrature modulation, and for carrying out quasi-coherent detection of a received signal, followed by A/D conversion; a baseband signal processor connected with the radio stage for carrying out baseband signal processing of the transmitted signal and the received signal; a transmission interface connected with the baseband signal processor for implementing interface with external channels; and a base station controller for carrying out control such as management of radio channels and establishment and release of the radio channels. The base station communicates with the external channels by mapping logical channels into physical channels. The CDMA signals are spread using a short code and a long code.
