Abstract: A vertical flow meter comprises a vertical barrel, an adjustment mechanism and an induction mechanism. The vertical barrel has a flow passage inside to house a vertical rod and a magnetic element coupling on the vertical rod. The adjustment mechanism straddles a holding plate and a scale plate that are located at two sides of the vertical barrel, and includes an adjustment portion at one side thereof, at least one adjustment member corresponding to a second elongate slot of the scale plate and fastening to the adjustment portion, a protrusive connection portion at another side opposite to the adjustment portion, and a connection plank connecting with the adjustment portion and protrusive connection portion. The induction mechanism is disposed at one side of the protrusive connection portion. Through magnetic attraction between the induction mechanism and the magnetic element, the adjustment mechanism can be moved upward or downward on the scale plate.

Abstract: An oven having an adjustable effective heating space includes an oven body with a scale and a space control knob on the outside to allow manual adjustment of the heating space. Through a transmission assembly and a lever assembly, the position of a heating assembly located in a heating chamber can be adjusted to form an effective heating space with another heating tube in the heating chamber. The size of the effective heating space can be adjusted in a stepless fashion according to user's requirements so that baking and roasting condition can be fine-tuned whenever desired without moving foodstuff or the oven. The oven thus formed provides multiple functions to heat the foodstuff effectively. Roasting can be done simpler and safer with less energy consumption.

Abstract: A calcium ion sensor is provided. The calcium ion sensor includes a metal oxide semiconductor field effect transistor, a sensing unit including a substrate, a ruthenium dioxide membrane formed thereon and a calcium ion sensing membrane formed on the ruthenium dioxide membrane, and a conductive wire connecting the metal oxide semiconductor field effect transistor and the sensing unit. The invention also provides a method for fabricating a calcium ion sensor, and a sensing system including the sensor.

Abstract: The present invention provides a labor-saving device for a fan head including a first driving module fixed on a supporting base board, a second driving module fixed on a connecting board, and an elastic element, wherein each driving module is composed of a motor, a curved handle and a connecting block. The first driving module fixed on the supporting base board is responsible for a back and forth horizontal movement, and the second driving module fixed on the connecting board is responsible for a back and forth vertical movement. The elastic element is mounted between the supporting base board and the connecting board for buffering the torque differential between the two motors, which are respectively moved in a horizontal direction and a vertical direction, so as to save labor of the fan head and further increase the life time of the fan head system.
