Abstract:
A pepper mill includes a driving member coupled rotatably to a container body and cooperating with the container body to define a receiving space, a grinding unit, a planetary gear mechanism, and an adjusting component. The grinding unit includes a coupling shaft extending rotatably and being movable in the receiving space, a stationary first grinding seat, and a second grinding seat co-rotatable with the coupling shaft. The size of a grinding space between the first and second grinding seats is adjusted when the coupling shaft and the second grinding seat move axially relative to the first grinding seat. The planetary gear mechanism includes a driving gear unit and a driven gear unit driven rotatably by the driving gear unit to drive rotation of the coupling shaft. The adjusting component is connected threadedly to the coupling shaft and is operable to drive the axial movement of the coupling shaft and the second grinding seat.
Abstract:
An image processing method combining compression and watermark techniques is provided. In the method, a block is taken as a unit, and two ordered dither arrays mutually conjugate are used to code an original image, so as to insert information of a watermark into the original image during the coding process. Accordingly, the method generates a compressed image gives consideration to the compression ratio, the image quality and the data safety. On the other hand, the method also provides a procedure to extract the watermark from the compressed image, in order to verify whether the compressed image has been modified illegally.

In a method of manufacturing MOSFET devices, and particularly to the trench-type MOSFET devices, embodiments of the present invention provide methods of forming bottom oxide layers having uniform thickness on the bottom of the trenches and avoiding undesired damage in the partial semiconductor substrate near the top of the trenches. In one embodiment, a method for manufacturing a trench-type MOSFET comprises providing a semiconductor substrate and forming a trench on the semiconductor substrate; forming a first oxide layer on a bottom and sidewalls of the trench and on the semiconductor substrate; forming a bottom anti-reflective coating (BARC) layer in the trench to cover the first oxide layer; forming a photoresist layer on the bottom anti-reflective coating layer; removing the photoresist layer; removing the bottom anti-reflective coating layer; and removing the first oxide layer on the sidewalls of the trench to form a bottom oxide layer on the bottom of the trench.
Abstract:
A rack includes a main frame, two rotary frames, and several holding rack parts; the main frame has lateral supporting portions at two ends thereof; the rotary frames are pivoted to respective ones of the lateral supporting portions of the main frame; each holding rack part is pivoted to the rotary frames at two ends thereof, and has several receiving holes thereon for objects to be passed through; thus, after objects are passed through the receiving holes and held on the holding rack parts, the objects will cause the rotary frames to change angular position due to gravity, and will always be upright.

Abstract:
A low noise step-down converter includes a rectified voltage output, a pulse generator, a rectifying diode, a rectifying inductor, a rectifying capacitor, and an impedance element. The rectified voltage output is provided for outputting a converted voltage. The pulse generator includes a pulse wave output. The pulse generator receives an input voltage and outputs a pulse wave through the pulse wave output. The rectifying diode is reversely coupled to the pulse wave output. One end of the rectifying inductor is connected to the pulse wave output for receiving the pulse wave while the other is connected to the rectified voltage output. One end of the rectifying capacitor is connected to the rectified voltage output, and the other end is electrically grounded. The impedance element at least provides resistance impedance and inductance impedance, wherein the rectifying diode and the impedance element are connected in series and are electrically grounded.
Abstract:
The present invention is to provide a swinging water massage bed for a user to lie on a bed board. The user can operate a controller to ascend the bed board and swing the bed board through a swing driving unit, or descend the bed board to a resilient layer of a water container. With a water jet device in the water container, water jets out to knock against the resilient layer for the user to be massaged so as to help the user sleep or relax.
