摘要： The invention relates to a method and apparatus for measuring a speed of an ultrasonic: wave propagated in a sample, even if there are bubbles in a sample. And it presupposes an ultrasonic speed measuring method for seeking a sonic speed in a sample in accordance with the propagation time of an ultrasonic wave propagated between an ultrasonic transmitter and an ultrasonic receiver by transmitting the ultrasonic wave from the ultrasonic transmitter. The apparatus of this invention is arranged that continuous oscillating waves are oscillated synchronizing the phase only with the receipt timing of at least one of receiving waves received by the ultrasonic receiver at every transmitting waves, and according to the continuous oscillating waves it is possible to measure the period of pulses oscillated by the local oscillator for determining the transmit timing.

摘要： When a cell load becomes higher than a call setup threshold value for a first channel (CS channel), a second channel (PS channel) is changed into a channel having a low transmission rate. Consequently, the cell load is reduced and no cell loss occurs in the first channel. Therefore, the call loss rate of a first communication service is lowered. Simultaneously, a handover threshold value is higher than the call setup threshold value for the first channel so that a failure rate of handover is lowered.

摘要翻译： 当小区负载变得高于第一信道（CS信道）的呼叫建立阈值时，第二信道（PS信道）被改变为具有低传输速率的信道。 因此，电池负载减小，并且在第一通道中不发生电池损耗。 因此，第一通信服务的呼叫损失率降低。 同时，切换阈值高于第一信道的呼叫建立阈值，使得切换的故障率降低。

摘要： In a mobile communication system, when a connection necessary to provide a service supporting high-speed data communication referred to as an MBMS (Multimedia Broadcast Multicast Service) is configured on an Iu interface, contention with the other packet communication service is eliminated. As a logical connection established between an SGSN (Serving GPRS (General Packet Radio Service) Support Node) and a Radio Network Controller in a Core Network 10, a PS (Packet Switching processing) functional connection for an existing packet communication service and a connection for a new MBMS service offering high-speed data communication are provided separately and independently from each other. This eliminates the contention between different types of services of the PS service and the MBMS service to thereby enable executing processings of such different types of services without being conscious of mutual processings. In addition, release processing of the connection may be executed independently to each service, thereby eliminating processing complexity in the SGSN.

摘要： A network connecting device 100 comprises a LAN I/F 130 for performing communications with a LAN, a N-ISDN I/F 170 for performing a connectionless transmission, and a ATM I/F 160 for performing a connection-oriented transmission. A plurality of networks having different transfer systems are separately used, and communication channels are switched as occasion demands. A connection table section 200 holds correspondence among individual communication channels. A channel setting control program section 500 allocates a communication channel for new communication data. A kicking-out program section 1300 makes a communication channel used for low-priority communication data available for high-priority communication data. A recovery program section 700 reallocates a communication channel for communication data that has changed a communication channel after completion of high-priority communications. Thus, during connecting the LAN with a wide area communication network, data packets currently under call setting control ca be prevented from staying, and line utilizing efficiency ca be increased.

摘要： A main switch with a low withstand voltage usable to prevent a leak current from flowing from a floated running power supply by way of the main switch even when the insulation between the main switch and the body grounding is reduced. A running power supply for supplying power to a running motor, which includes a plurality of batteries connected in series to each other, is kept in the floating state with respect to the body grounding. Moreover, there is provided a step-down DC-DC converter of an input-output insulation type. A diode and a main switch are provided from a battery constituting part of the running power supply in this order to supply a starting power or starting signal to the DC-DC converter for starting the DC-DC converter. Thus, power is supplied to the input side of the DC-DC converter from the running power supply, to obtain a step-down accessary power supply VB.
