摘要:
A recording medium suitable for use in an impedance matching apparatus adapted to a waveguide transmitting a microwave to a load. The apparatus includes detecting diodes and a computer. The recording medium includes a program, which includes predetermined approximate expressions. The predetermined approximate expressions recorded in the program correspond to the detecting diodes. The program causes the computer to compute an approximation value of input power to the waveguide using the respective predetermined approximate expressions and output voltages of the detecting diodes. The program also causes the computer to compute coefficient of reflection and phase of the input power using the approximation value; determine whether impedances of the waveguide and the load match with each other based on the computed coefficient of reflection and phase of the input power; and execute automatic impedance matching of the impedance matching apparatus when the impedances of the waveguide and the load do not match with each other.

摘要:
An adhesive filler apparatus is disclosed comprising an injector and a support portion, the injector comprising a pressure buffer tube made of an elastic material and check valves adjacent both ends of the pressure buffer tube, the support portion comprising a base member and a projection. The adhesive filler apparatus disclosed is used as follows: A hose connected to a pump is coupled to one end of the pressure buffer tube so that the nozzle of the hose presses the check valve to clear its closure, allowing an adhesive to be fed in the pressure buffer tube. The hose is disconnected from the fed and swollen tube, causing the check valve to close the end of the tube. The fed injector is coupled to the support portion fixed on the crack developed in a concrete structure, etc., whereupon the projection on the support portion presses the check valve to open the end of the tube, thereby allowing the adhesive in the tube to be filled in the crack by gradual and continuous contraction of the elastic tube. Where the quantity of adhesive reserved in the tube is not enough, adhesive can be supplemented in the tube through the other end of the tube left idle so that the injector need not be detached from the crack for supplementation of adhesive in the tube.

A fuel gas station, a fuel gas filling system, and a fuel gas filling method which can check whether information on temperature of the inside of a fuel tank is correct, so that a fuel tank is properly filled. The fuel gas station calculates a difference of temperature between a temperature of the inside of the fuel tank and a temperature of fuel gas to be supplied to the fuel tank after supplying of fuel gas for a predetermined length of time. When the calculated difference of temperature exceeds a predetermined threshold value, the fuel gas station determines that the information on temperature of the inside of the fuel tank is abnormal, and reduces at least one of supply flow and supply quantity of fuel gas as compared to when such information is normal.

A gas filling system (1) includes a gas tank (30); a gas filling device (2) that fills gas into the gas tank (30); and a controller (24) that calculates a temperature increase ΔT and a pressure increase ΔP in the gas tank (30) during a predetermined period of time (t seconds) that elapses from a start of gas filling. The controller (24) selects a filling rate map (Ma, Mb) from a prepared filling rate map group on the basis of the calculated temperature increase ΔT and the calculated pressure increase ΔP. The gas filling device (2) carries out gas filling using the filling rate map selected by the controller (24).
摘要:
A gas filling apparatus in the gas filling system includes a precooler for cooling hydrogen gas supplied from the gas supply source (11) and discharges the hydrogen gas cooled by the precooler to fill the hydrogen gas into the gas tank. The temperature of the hydrogen gas cooled by the precooler is detected by a gas temperature sensor that detects, upstream of the gas tank, a temperature of the hydrogen gas cooled by the precooler. A flow rate controller controls a filling flow rate of the hydrogen gas to be filled into the gas tank, based on the detected temperature of the hydrogen gas. For example, when the detected temperature of the hydrogen gas is high, the filling flow rate is reduced as compared to that when the detected temperature of the hydrogen gas is lower.
