Patent TW-453935-B (TW)
Title: Hammering screwdriver with disengagable striking mechanism
Inventor: GEORGIOU YIANNIS
IPC: B25B21/02
Filed: 1998-10-28
Granted: 2001-09-11
Abstract: A hammering screwdriver 1 for tightening and loosening screws offers the possibility of operating the rotating action alone when tightening the screws, and a rotation/hammering action when loosening the screws. This is primarily attained by the construction of the cam controller casing 2 between which and the hammering mechanism cage 6 a ball 10 is arranged. With this exclusively rotating motion, this ball 10 lies in a salient 16 below an elevation 8 on the head end 7 of the cam controller casing 2. With rotation/hammering motion, the ball 10 is moved over the track 3 to the cam controller casing 7 until it reaches the elevation 8. Here the cam controller casing 2 moves forward in an axial direction owing to which hammering action occurs.

Title: Apparatus and method for cooling the bearings of a godet for advancing and guiding yarn
Inventor: RITTER WALTER
IPC: D02J13/00
Filed: 1998-11-17
Granted: 2002-06-11
Abstract: In a godet for advancing and guiding an advancing synthetic filament yarn, the bearing housing for supporting a shaft consists of an inner bearing support and an outer cooling body, which are in a heat conducting contact with each other. Cooling of a bearing within the bearing support is enhanced because the material of the cooling body has a coefficient of thermal conduction which is greater than the coefficient of thermal conduction of the bearing support material. In a heated godet, a cup-shaped godet casing fits over the end of the shaft, and a stationary hollow cylindrical support is fit over the shaft within the godet casing. An annular space is defined between the support and the shaft, and a heating element is mounted to the circumference of the support. The bearing housing at least partially defines openings that provide cooling air to the annular space.

Title: Serial pipeline digital-to-analog converter with Gamma correction and its method
Inventor: JANG JIA-YUAN
IPC: H04N1/40
Filed: 1999-09-09
Granted: 2001-12-01
Abstract: The present invention is related to an apparatus and method converting digital signal into analog voltage, in which the apparatus contains a pair of reference voltage selectors, a pair of control couplers and voltage accumulator. The reference voltage selector selects the first and the second voltage levels as the first and the second voltage source, respectively. Corresponding to each bit voltage level of the first part digital signal, control coupler is electrically coupled with the first voltage source or the second voltage source as the charging power source. Voltage accumulator is used to alternately perform charging and redistributing steps onto the output capacitor so as to generate analog voltage. The converting method contains the following steps. At first, reference voltage level is divided into the first set and the second set, in which the first voltage and the second voltage sources are selected, respectively. Based on the magnitude of voltage level for part of the bits of digital input signal, the first or the second voltage source is selected as the charging power source. In addition, the output capacitor is coupled with the first or the second capacitor. Until after the bit, which is the next bit after all of the bits are treated, the voltage on output capacitor is analog voltage.

Title: Manufacturing method of multi-layer gate oxide layer
Inventor: YU MO-CHIUN
IPC: H01L21/76
Filed: 2000-01-28
Granted: 2001-07-01
Abstract: The present invention provides a manufacturing method of multi-layer gate oxide layer for removing the difficulty in forming a silicon oxide layer for being used as an interface layer between the substrate and other dielectric material in the process for forming a multi-layer gate oxide layer. In the conventional process, due to the restriction of the minimum thickness of the deposited silicon oxide layer, it is difficult to increase the overall dielectric constant of the gate oxide layer. Therefore, the conventional skill can not be applied to the gate process with smaller gate width. The present invention performs a nitrogen plasma process to the silicon oxide layer thereby decreasing the thickness of the pure silicon oxide layer, and also forming dielectric material with a higher dielectric constant on the silicon oxide layer, so as to overcome the difficulty issue.
