摘要:
An image display device is arranged to convert analog video signals into digital video signals and display the corresponding image to the digital video signals. The image display device provides a variable delaying circuit for delaying an analog video signal of each color or a clock variable delay circuit for delaying a dot clock for generating each color dot clock and supplying each color dot clock as a conversion timing signal of an analog-to-digital converting circuit of the corresponding color. This kind of delay circuit is served to adjust a phase of the analog video signal or the dot clock of each color, thereby suppressing color blur even if the analog video signal contains skews among the colors.

Disclosed is a thermostable DNA polymerase preparation which can illimitably reduce the risk of false positivity in the detection of a subject microorganism utilizing a gene amplification reaction and therefore enables the selective amplification of DNA for detecting the subject microorganism even when the amount of the subject microorganism is small and therefore the amount of DNA collected therefrom is extremely small, and can be produced at a reduced cost. Also disclosed is a method for quantifying or quantifying/identifying a subject organism to be detected rapidly, conveniently and with high sensitivity using the preparation of the present invention.

A wheel position detecting device and a tire air pressure detecting device including the wheel position detecting device are provided. The wheel position detecting device includes triggering devices and a receiver mounted on the vehicle-body side, and transmitters mounted on the wheels. Each triggering device outputs a trigger signal to each transmitter. In response to the trigger signal, each transmitter transmits a frame to the receiver. The receiver receives the frame and judges whether the transmitter is mounted on a subject wheel, based on whether reception strength indicated by reception strength data stored in the frame is within a range set in advance.
