Title: Memory structure in ferroelectric nonvolatile memory and readout method therefor
Inventor: ISHIWARA HIROSHI
IPC: G11C14/00
Filed: 1999-08-18
Granted: 2001-04-01
Abstract: Each of memory cells of a ferroelectric nonvolatile memory includes a MOS field effect transistor and first and second ferroelectric capacitors whose remnant polarization amounts are substantially equal to each other. One-side electrodes of the first and second ferroelectric capacitors are connected to the gate electrode of the MOS field effect transistor. Information is stored by polarizing the thin ferroelectric films of the first and second ferroelectric capacitors in opposite directions to each other with respect to the gate electrode of the MOS field effect transistor. Information is read out by applying a positive voltage pulse to one of the other electrodes of the first and second ferroelectric capacitors while the other one of the other electrodes is kept in the electrically floating state. Further a negative voltage pulse having an absolute value smaller than the positive voltage pulse may be applied, if necessary.

Title: Pressing method of eight-layer circuit board and its manufactured product
Inventor: JENG YU-CHIANG
IPC: H05K1/03
Filed: 1999-08-26
Granted: 2001-08-01
Abstract: The present invention provides a pressing method of eight-layer circuit board and its manufactured product. The first, third, sixth, and eighth layers of the circuit board are grounding layers. The fifth layer is a power layer. An insulating layer is placed in between the fourth and fifth layers and has a thickness of 2-6 mil. A second insulating layer is placed in between the third and fourth layers and in between the sixth and fifth layers, and has a thickness of 3-11 mil. A third insulating layer is placed in between the second and third layers and in between the seventh and sixth layers, and has a thickness of 3-9 mil. A fourth insulating layer is placed in between the first and second layers and in between the eighth and seventh layers, and has a thickness of 2.5-6.5 mil. Consequently, the signal wiring layer of each layer is matched in impedance, thereby decreasing the reflection of high speed signal and the electro-magnetic interference, so that the circuit board is suitable for the layout of high speed signal.

Title: Method for filtering dirty air and device therefor
Inventor: CHEN JIUN-HAU
IPC: B01D47/00
Filed: 1999-09-07
Granted: 2002-07-01
Abstract: The present invention relates to a method for filtering dirty air and a device therefor. The method comprises feeding dirty air into water and using the flapping effect of a swaying device on the discharge end of the dirty air to disperse the dirty air into tiny bubbles in order to increase the contact area between air and water so that dirty particles in the tiny bubbles combine with water molecules to form a precipitation; mounting a net under water for filtration and preventing larger or lighter particles in the dirty air from floating to the surface of water. Meanwhile, the swaying current increases the contact area between particles and water thereby achieving effective air filtration. Furthermore, a clean air suction device can be installed at a location near the surface of water to suck in clean air and transport air to a dirty air region to purify air.

Title: Circuit arrangement for bias adjustment of bus levels
Inventor: MORES ROBERT
IPC: G06F13/40
Filed: 1999-10-04
Granted: 2003-02-11
Abstract: In a system for the transmission of logic levels via a bus the recessive level, being of higher impedance in comparison with the dominant level, is not adjusted by means of a resistor but by means of a termination arrangement with three break points in the current/voltage diagram. In the third quadrant of the current/voltage diagram this termination arrangement has a resistance which is higher than that of a lead terminated by means of a linear resistor. In the first quadrant the rise of the characteristic up to a voltage below a receiving threshold is steeper than in the case of termination by means of a resistor. Subsequently, in the first quadrant the characteristic is subject to a current limitation which is effective from a voltage below the receiving threshold to a value beyond the working point of the dominant driver. Beyond the working point of the dominant driver the current limitation is removed again, so that the rise is steeper than in the case of termination by means of a resistor. This termination arrangement optimizes the ratio of the value of the driver currents, and the associated radiation via the bus, to the speed at which a level is adjusted on the bus. Moreover, the tolerance in respect of ground offset is thus improved and also the resistance to radiation.

Title: Brine tank for water softening system and salt grid in brine tank
Inventor: WILFONG RUDY B
IPC: B01J49/00
Filed: 1999-11-23
Granted: 2004-05-11
Abstract: A salt grid for supporting salt above a portion of a concentrated brine solution in a brine tank for use in a water softening system. The grid comprises first and second platforms disposed at first and second elevation levels with respect to the vertical wall of the brine tank. The fluid level in the brine tank can be adjusted to be higher than the lower platform of the salt grid but lower than the upper platform of the salt grid. In this manner, salt dissolves only above the lower platform part of the grid and consequently, the dirt included in the salt only passes through the lower platform of the grid. The brine well which transports brine solution from the brine tank to the resin tank is located away from the localized area in which the dirt collects at the bottom of the brine tank. Leg extension members may be attached to the supporting legs of the salt grid to further raise the salt grid above the bottom of the brine tank, thereby increasing the volume of brine solution which forms below the salt grid.

Patent TW-452537-B (TW)
Title: Process and device for temperature control of mold tools of injection molding machines
Inventor: WITTMANN WERNER
IPC: B29C45/78
Filed: 1999-11-24
Granted: 2001-09-01
Abstract: The temperature control of mold tools is generally rather complex, especially in the production of CD blanks, since on the one hand during production large amounts of heat must be dissipated, this requires a large amount of coolant. Furthermore, in many cases, especially in the production of CD blanks, the flow of coolant in certain phases of the production cycle must be interrupted; this imposes high demands on the technical structure of the temperature control circuit or its control, since the pressure in the temperature control circuit may not drop, in order to ensure reliable and uniform cooling of the mold or the production material. It has been found that when, viewed in the flow direction, there are valves only following the mold tool for cycling, i.e. for interrupting or restarting the flow of the temperature control medium through the mold tool, a much more uniform pressure behavior of the temperature control medium can be achieved during the production process, since the lines in the mold tool are not completely closed, but on one side, on the supply line, they remain open.
