Title: Roller blade skate wheel
Inventor: CHEN DE-LIN
IPC: A63C17/22
Filed: 2000-04-15
Granted: 2001-07-21
Abstract: This invention is related to a roller blade skate wheel, wherein the wheel rim mainly includes a bearing core; a hub for retaining a tire; and a rim for connecting the bearing core and the hub. The rim has a width that is less than that of the hub and the bearing core, and the distance from the hub to the outer surface of the tire reduces from the frontal face towards the opposing lateral sides, such that kinetic energy of the skating can be accumulated and recovered by means of the resilience of the tire, and the resilient deformation of the hub and the rim. Further, when the skate wheel assumes an inclined position, the reducing distance from the hub to the outer surface of the tire increases the frictional coefficient and damping force of the tire so as to increases the frictional force between the tire and the ground so as to prevent from skidding during skating.

Inventor: SHIOBARA TOSHITAKA
IPC: H01J37/32
Filed: 2000-06-20
Granted: 2001-07-21
Abstract: In a plasma-enhanced etching process, the end point of the etching is detected based on the light intensity of the plasma and the second derivative of the light intensity. First, magnitude of the light intensity is judged based on a threshold to determine whether the etching area ratio is large or small with respect to the total area. Then, the second derivative of the light intensity is calculated after selecting sampling time interval based on the judgement of the etching area ration. The end point is detected when the second derivative assumes zero after exceeding a threshold in the absolute value thereof.

Title: High-voltage MOS transistor and method for fabricating the same
Inventor: INOUE HARUKO
IPC: H01L27/088
Filed: 2000-09-20
Granted: 2002-06-21
Abstract: In a high-voltage MOS transistor, source/drain offset regions have the same dopant concentration and the same diffusion depth but the length Ls of the source offset region is set greater than the length Ld of the drain offset region. Accordingly, the resistance value of the source offset region increases, thus raising a source voltage VS, too. As a result, a substrate voltage VW minus a forward biased breakdown voltage of silicon can be kept equal to or less than the source voltage VS more easily, and therefore, a sustaining breakdown voltage of the transistor can be increased.
