摘要： PROBLEM TO BE SOLVED: To solve the problem that hydrogen having invaded into a pressure and differential pressure transmitter from outside or internally generated hydrogen and hydrocarbons turn into foams in a pressure guiding path to invite drifting of indicated values and failure to output accurate values.SOLUTION: In a pressure and differential pressure transmitter in which a pressure guiding path encloses sealing liquid for transmitting pressure, a space is to be formed between a diaphragm and a body side wall face. The pressure guiding path is connected to the body side wall face, and a pressure received by the diaphragm is transmitted to a sensor via the sealing liquid enclosed in the space and the pressure guiding path. The configuration is such that a hydrogen adsorbing material for adsorbing hydrogen atoms in the sealing liquid is disposed at least in the sealing fluid, the body side wall face or part of the area extending from the body side wall face to the sensor.

摘要： PROBLEM TO BE SOLVED: To provide a digital modem which is suitable for a transmission line that is not in good condition, high in frequency usage efficiency, and of simple configuration. SOLUTION: Spread signal data of 256 samples are stored in order of addresses "0" to "255" in a spread signal memory 13. The spread signals represented by the spread signal data have a nearly constant power density in a prescribed bandwidth and sharp autocorrelation characteristics. Corresponding to the bit value of transmission data branching off by a transmission control circuit 11, an address forming circuit 12 forms addresses and outputs them and lets the spread signal memory 13 output the spread signal data of a first to a 256th sample or the spread signal data of a 128th to a 256th sample, and a first to a 127th sample. The following 64 addresses are inputted, and a guard interval is added. These are subjected to digital-analog conversion through a D-A converter 17, and sent out to a transmission line.

The flow rate is determined by calculating the flow velocity of the fluid from the propagation time of the ultrasonic wave. COPYRIGHT: (C)2010,JPO&INPIT
