Abstract: A fixing mechanism includes a base whereon a protrusion is formed, an elastic component installed inside the base, and a supporting component wedged inside the base. An end of the supporting component contacts against the elastic component, and the other end of the supporting component is for supporting a board. The fixing mechanism further includes a clamping frame pivoted to the base. A slot is formed on the clamping frame. The clamping frame and the supporting component clamp the board together when the protrusion of the base is inserted inside the slot on the clamping frame.

Abstract: Through a low-dose irradiation, a seaweed's growth becomes fast and its production is improved as well. By doing so, a material for biomass energy is provided.

Abstract: One or more piezoelectric pads are disposed into a keyboard and electrically connecting to a rechargeable battery of an electronic device or a portable electronic device. When one button of the keyboard is pressed, the movement of the button pushes and deforms the corresponding piezoelectric pad to generate a piezoelectric voltage for charging the battery. The electronic device or the portable electronic device can deal with power shortage during usage with the feature of transforming mechanical power into electrical power by using piezoelectric pads in the keyboard.

Abstract: An apparatus is disclosed for growing algae by ionizing radiation. The apparatus includes a container for containing medium for the growth of algae, a filter disposed in the container, a 3-dimensional rack disposed in the container, an adherent element wound on the 3-dimension rack so that spores of the algae can be planted in the adherent element, a radiation element disposed in the container for irradiating the spores and a timepiece connected to the radiation element.

Abstract: A wild seaweed, like sea lettuce, is picked and germ cells are released from the seaweed. The germ cells then obtain adherence and are sprouted into youngs of the seaweed so that the seaweed can be cultivated artificially and productively and can be supplied as a material for biomass energy.

Abstract: Algae are irradiated to obtain a hormesis so that its thickness is increased or its growth time is shortened. A cubic rack with an adhesion unit is used so that more algae are planted to be cultured on the adhesion unit through the irradiation for mass production.
