    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.

    摘要: A method for producing aldehydes, which comprises reacting an olefinic unsaturated compound with carbon monoxide and hydrogen in a liquid phase in the presence of a Group 8 metal-phosphite complex catalyst, wherein a reaction product solution containing the complex catalyst and a high boiling by-product, obtained by the reaction, is intimately contacted with an extraction solution containing a polar solvent, to have either the complex catalyst or the high boiling by-product extracted selectively, followed by phase separation to separate a layer of the extraction solution from a layer of the reaction product solution.
