Abstract: A reinforcing bar material is coated with a high adhesion anticorrosion film that increases adhesion strength to concrete. The film is applied by heating a reinforcing bar material, spraying and melt-adhering an epoxy powder coating material onto the reinforcing bar material while a temperature on a surface of the reinforcing bar material is between 200 and 250° C. so as to form a first anticorrosion film, and under the same temperature condition spraying and melt-adhering an epoxy powder coating material with acrylic resin beads having a particle diameter 2.5 to 3 times that of the epoxy resin powder mixed in on a surface of the first anticorrosion film in a molten state so as to form a second anticorrosion film having numerous projections, thereby providing a coating without pinholes.

Abstract: In an OFDM receiver with a diversity configuration having a plurality of demodulation modules, to perform FFT window position recovery and clock recovery, the gain values calculated by the AGC units (16, 26) provided in the demodulation modules for adjusting the level of the received signal are supplied to a correlation combiner (35); the correlation combiner (35) multiplies the correlation signals supplied from the correlation detectors (17, 27) in the demodulation modules by coefficients calculated from the gain values, then adds the products to generate a combined correlation signal and supplies it to an FFT window position recovery unit (32) and a clock error detector (33). FFT window position recovery and clock recovery can thus be performed properly without depending on any one demodulation module.

The window control circuit 13 sets and controls the FFT window position of an FFT circuit 5 in response to a guard correlation signal fed from a guard correlation signal generating circuit 12 and a signal fed from the accumulator 11.

A first end portion of the valve shaft is arranged protruding outside the casing. A throttle valve is secured to the valve shaft inside the bore. An actuator is coupled to the first end portion to open and close the throttle valve. The second shaft support part is located in a bypass passage downstream from a bypass valve and has an opening in which a cap formed with a through hole is fitted. The inside of the second shaft support part is allowed to communicate with atmosphere through the through hole, the bypass passage, and others so that an end face of a second end portion can be subjected to atmospheric pressure.
