Abstract: An adjustable mounting bracket includes two frames juxtaposed to slide on each other and attached by nuts and bolts. Each of the two frames is essentially U-shaped with an internal T-shaped opening. The T-shaped opening is formed by a shoe plate formed between the end plate and two side plates. Slots and holes in the shoe plate are used to connect the two frames together and adjust the central working space for use with either a circular saw or a router. Slots in the shoe plate in conjunction with locking pieces are used to attach the power hand tool to the mounting bracket. The length of the mounting bracket is adjustable to be suitable for power hand tools such as a circular saw or a router that have different sizes. Consequently, the user only needs to use a single mounting bracket so material and cost are saved. Furthermore, the two frames of the present invention are identical so that the frames are easy to be manufactured.

Abstract: A positioning hinge for a notebook computer has multiple collars each provided with an obliquely formed friction plate. The friction plate engages a side face of an extension of a bracket configured to attach securely to a body of the computer to provide the necessary friction force to hole the monitor at an angle relative to the body of the computer. With such an arrangement, the friction force can be adjusted to accommodate different weights of the monitor by reducing or increasing the number of the collars.

Abstract: A bean sprout culture box with a sprinkling device has a water tray, at least one culture case, a sprinkling case, a hollow sprinkler pivotally mounted in the sprinkling case and an inlet valve. The sprinkling case has multiple drain holes defined in the bottom of the sprinkling case. The hollow sprinkler has a chamber defined in the bottom of the sprinkler and multiple posts extending down from the sprinkler at the end opposite from the chamber. With such a bean sprout culture box, the sprinkling device can automatically sprinkle by the effect of gravity on the water, and electricity is not needed.

Abstract: In present invention we provide a vertical two-transistor memory cell consisted of a MOS transistor and an ETOX cell. One of the drain or source of the MOS transistor is connected to the control gate of the ETOX cell, the other is acted as the control gate of the vertical two-transistor memory cell and is connected to a control line. And the gate of the MOS transistor is acted as the select gate of the vertical two-transistor memory cell and is connected to a word line. The drain of ETOX cell is connected to a bit line, and the source of ETOX cell is grounded. The vertical two-transistor memory cell can be programmed by channel Fowler-Nordheim tunneling of electrons which is injected from the substrate through the channel and tunnel oxide into the floating gate. Such memory cell can avoid the word line disturb by controlling the word line.
