Abstract: In a water purifier or other liquid dispenser, a sensor configured to transmit and receive a distance measuring signal is installed in a water discharge module moving vertically or disposed at the front of a main body, to sense a height of the inlet of a container accurately without a no-response duration of the sensor. Additionally, in the water purifier, the water discharge module discharges purified water at a point spaced a certain distance apart from the inlet of the container, to prevent the inlet of the container from contacting the lower surface of the water discharge module.

Abstract: A golf putter with a dual-friction curved face including a shaft having a grip provided at its upper end, and a putter head connected to the lower end of the shaft and having a putter face convexly curved so as to substantially correct directional error in putting, the golf putter wherein the putter face has a radius of curvature of approximately 400 mm to approximately 900 mm so as to maximize a direction error correcting effect, the shaft which is the rotation center of the putter head is positioned approximately 5 mm to approximately 20 mm in rear of the foremost part of the putter face so as to substantially correct the directional error, and the putter face has a dual-friction structure in which friction resistance differs in a heel-to-toe direction and in a vertical direction to decrease directional error due to inaccurate putting strokes and to increase top spin to a golf ball.
