An RF directional coupler circuit assembly for matching high frequency cable TV apparatus includes a cover body, and a printed circuit board. The cover body includes a space. The space includes a bottom surface. An RF directional coupler circuit is arranged on the printed circuit board. A 0.01 mm˜2 mm gap is formed between the RF directional coupler circuit and the bottom surface when the printed circuit board is deposited in the space. The distance between the printed circuit board and the cover body is shorten because of the gap, so that the reflections of the high frequency signals and the signal fading are decreasing to achieve matching high frequency impedance characteristics.

A food processor includes a control unit that is operable in accordance with an initial control signal from a switch unit so as to activate a motor unit to operate in a sequence of an initial judgment mode and a food processing mode. The control unit switches operation of the motor unit from the initial judgment mode to the food processing mode upon determining a first target rotary speed in accordance with a motor rotation signal generated by a sensor unit for indicating a rotary speed of the motor unit during operation of the motor unit in the initial judgment mode so as to drive rotation of a cutting blade unit provided in a container to process food items contained in the container. The control unit activates the motor unit to rotate at a second target rotary speed associated with the first target rotary speed during operation of the motor unit in the food processing mode.
