Title: Headstock of a polishing machine
Inventor: SAITO HIDEO
IPC: B24B37/30
Filed: 1997-10-08
Granted: 2000-01-01
Abstract: The present invention provides a headstock of a polishing machine, having a simple structure and capable of tracing a pad surface. The headstock of the present invention is formed of a spindle, a holder plate, a spherical bearing, and a plate spring. The holder plate is connected to a lower end portion of the spindle via the spherical bearing and the plate spring. A workpiece is attached to the lower surface of the holder plate. The spherical bearing has a center of tilting movement on a rotation axis of the spindle. The holder plate has a balance plate. The center of gravity of the holder plate including the balance plate coincides with the center of tilting movement of the spherical bearing. The plate spring has an axisymmetric shape. More specifically, the plate spring has an opening portin at the center and a plurality of arm portions extending to the outer periphery in the diameter direction. The plate spring is connected to the lower end of the spindle by use of first fitting holes which are formed along the inner periphery, and the plate spring is also attached to the holder plate by use of second fitting holes which are formed in the distal end of the plate spring. The first and second fitting holes are respectively located on small- and large-diameter circles which are concentrically arranged around the rotation axis of the spindle.

Title: Straight-line driver and its driving method
Inventor: PAN JIA-TIAN
IPC: H01L41/00
Filed: 1997-11-06
Granted: 2000-12-11
Abstract: A straight-line driver and its driving method comprises mainly two driving bases with a piezoelectric element therein and the two driving bases are connected with a piezoelectric element. The straight-line driver is capable of moving steadily for a long distance and permits users to control the quantity of movement more precisely, by which the weakness of prior art can be effectively improved since the distance of movement can satisfy the need of microminiaturization through the characters of extension and shrinkage of the piezoelectric element along the track it is located.

Filed: 1998-01-15
Granted: 1999-07-11
Abstract: The present invention relates to a device for capturing the filth of plant plankton and capture method using the same. The device can use water permeable and non-permeable materials that can be easily and inexpensively constructed according to the provided instructions. In addition, the deployment of the same device at the bottom of shallow water area such as lakes and ponds by the established rules helps facilitate and won't inhibit the growth of plant plankton in the waters, and conversely, helps purify the water quality by the action of plankton that absorbs and removes the inflow of nitrogen and phosphorus. At the same time, the device uses natural force to capture, pile up and recycle filths produced by the plankton and their dormant spores and keep them from spreading to the waters system. Thus in comparison with prior arts, this device is not only relatively simple in design, the absence of chemicals in its application makes it a safe and cleaning device in the waters system to carry out water purification treatment.

Title: Process for layer production on a surface
Inventor: KARCHER WOLFRAM
IPC: C23C16/02
Filed: 1998-02-04
Granted: 2001-11-11
Abstract: In chemical gaseous phase deposition (CVD = chemical vapor deposition), there is frequently the problem that there is still an aggressive gas in the reaction chamber from the preceding layer production process. This aggressive gas can be a remainder of a process gas used for layer production or can be a remainder gas produced by the reaction of the process gasses. The aggressive gas can cause undesirable reactions on the surface of the semiconductor product, which damage the semiconductor product. To solve this problem, a process for layer production on a surface is provided in which before and/or during the heating of the surface to the reaction temperature, at least one protective gas is supplied to the surface. By means of the protective gas, on the one hand, the aggressive gas still remaining in the reaction chamber is thinned and on the other hand, a part of the protective gas adsorbs onto the cold surface so that on the surface, preferably reactions of the aggressive gas with the protective gas occur and the surface layers themselves remain essentially undamaged.

Granted: 2000-10-01
Abstract: An exercise bicycle including a frame having a seat and handlebars, a high-inertia flywheel having a hub at a center of rotation, the flywheel being rotatably supported on the frame at the hub, and a drive train including a drive sprocket, a crank arm attached to and extending from the drive sprocket, and a pedal attached to the crank arm, the drive train being rotatably supported by the frame. The drive train also includes a slave sprocket fixed to the flywheel at the hub, with the drive and slave sprockets connected in a direct-drive relationship, the drive train driveable in a forward and rearward directions to cause the flywheel to rotate. A clutch mechanism is positioned in engagement with the slave sprocket and the hub to create a frictional engagement between the sprocket and the hub, and to establish a break-free force threshold. When the drive train is actuated in the forward direction, the slave sprocket and the hub move together, and when the drive train is actuated in the rearward direction under the influence of a force greater than the break-free force threshold, the clutch mechanism slips between the slave sprocket and the hub, allowing the slave sprocket and the flywheel to move independently of one another.

Abstract: A full-swing high voltage data latch for operation at relatively high power supply voltages. The full-swing high voltage data latch has a high voltage rail for supplying an upper voltage level and a low voltage rail for supplying a lower voltage level. A latch circuit is coupled to the upper voltage rail and to the lower voltage rail. The latch circuit is used for generating an output signal. The output signal switches with respect to an input signal when the high voltage rail and the low voltage rail operate in a low voltage mode and is latched in a state that the output signal is currently at when the high voltage rail and the low voltage rail changes state from said low voltage mode to a high voltage mode. An input circuit is coupled to the latch circuit for sending an input signal and a complementary input signal to the latch circuit. An output driver circuit is coupled to the latch circuit for receiving the output signal from the latch circuit and for providing a full-swing output data latch signal. The full-swing high voltage data latch ranges from the upper voltage level of the high voltage rail to ground.

Abstract: An electrical connector for electrically coupling with an external plug, includes a housing, a plurality of contacts, and a pair of spring latching means disposed in opposite slots of the housing. Each latching means consists of a planar portion, a protrusion extruded out of the planar portion, a first support section and a second supporting section respectively bent from the planar portion along different directions, and a tab formed on a tip of the planar portion. Meanwhile, the first supporting section of each latching means is engagingly inserted within an alleyway formed on a rear wall of the corresponding slot, and the planar portion is spread with regard to the inserted first supporting section and the tab is restricted within a concave formed on a front wall of the slot to have the planar portion preloaded. And, the second supporting section abuts against a lateral wall of the slot. By way of the intensified resiliency exercised by both the first and second supporting sections, the protrusion of the latching means is capable of rapidly and sufficiently snap-fitting with a corresponding notch formed on the plug and creating a resounding audio effect easy to inspect the locking status between the mated connector and plug.
