摘要:
Using a network in which one master station modem 105 and multiple slave station modem 106, 107, 108 are physically connected by rudder connection or bus connection with a telecommunication line 121, the measurement result of the S/N ratio between the master station and slave stations is once collected in the master station at the initialization stage, pairs of the modulation method, by which all modems can demodulate at high probability, and transmission voltage are calculated based on this data, and the calculation is transmitted to all slave stations; and at a normal transmission stage, information regarding the coordination and control of the network is transmitted in accordance with this setting. Thus, one-to-multi communication is realized, guaranteeing an access right.

A mobile radio communication system (100) includes: a virtual private network relay device (105) for establishing an Ipsec tunnel with a network relay device (104) arranged in a private network (102) via a public network (101) and establishing an Ipsec tunnel with a mobile radio terminal device (110), thereby relaying connection from a public radio LAN system (103) of a mobile radio terminal device (110) to a private network (102); a connection authentication server (108) for authenticating the connection to the public radio LAN system (103) of the mobile radio terminal device (110); and a radio LAN access point (109) for relaying the connection authentication procedure of the public radio LAN (107) performed between the mobile radio terminal device (110) and the connection authentication server (108).
摘要:
A wireless terminal in which the probability that an incoming call is accepted is greatly improved and the load on the circuit switch is lightened. Each of such wireless terminals (120) comprises a wireless LAN interface (126), a cellular wireless interface (127), and a telephone number table (1241) storing an extension number and a cellular number both associated with each other. Each of the wireless terminals (120) searches the telephone number table (1241) on receiving a call switch request from the circuit switch (111), identifies the cellular number concerning the call switch request, and automatically switches the call for the wireless terminal corresponding to the cellular number to a cellular telephone call.

An optical fiber coupler reinforcing member comprises an approximately rectangular member formed by a hard material, and has a flat surface along the longitudinal direction thereof. In addition, the shape thereof in cross-section is a hexagonal shape which inscribes a cylindrical member. Furthermore, a recess having a U-shaped cross-section is formed in the longitudinal direction of the above-mentioned approximately rectangular member and houses coupling section. The coupling section housed within the recess is fixed at both ends of the recess by an adhesive or the like. In addition, both ends of the inner wall surface of the recess have been given bevel sections. As a result, the optical fiber coupler reinforcing member having high reliability at low cost, with which the strength with respect to external force is improved and with which processability and the assembly operations of the optical fiber coupler are easy, are provided.

A valve timing control apparatus for an internal combustion engine has a lock pin that is movably provided in an accommodation hole of one of vanes of a rotor. A screw portion is formed along part of the outer circumference of the lock pin, which is fixed to a shaft of a motor. When hydraulic pressure control is performed to maintain a housing and the rotor in a predetermined intermediate phase, the lock pin moves in the axial direction of a cam shaft in response to rotation of the motor independently of the hydraulic pressure control, and engages a lock recess portion formed in a sprocket.

The present invention provides a method for manufacturing freeze-dried blood cells, stem cells and platelets comprising the steps of: pre-treating a liquid selected from the group consisting of blood including blood cells, bone marrow fluid (hemopoietic stem cells), and platelets in blood plasma, with a solution containing at least one substance selected from the group consisting of saccharide, biopolymer, acid and acid salt; conducting granulation of the aforementioned pre-treated liquid into a granules of a predetermined size; performing rapid cooling of the granules; and drying the resultant frozen material by sublimation of the water content contained therein.
摘要:
An apparatus for quantitative secondary ion mass spectrometry comprising a sealed chamber for storing a sample containing a light impurity element which is to be analyzed, secondary ion generating means for bombarding a primary ion beam onto the sample so as to allow the sample to emit a secondary ion of the light element, and quantitative analyzing means for detecting the secondary ion so as to quantitatively analyze the light element contained in the sample. First evacuating means evacuates said sealed chamber to an ultrahigh vacuum during quantitative analysis. First cryopanel means is arranged to surround the sample, and first cooling means keeps said first cryopanel means at a cryogenic temperature during quantitative analysis so that said first cryopanel means adsorbs a gas present in said sealed chamber.
