Title: Passive element circuit
Inventor: YAMAGUCHI KEIKO
IPC: H01L21/822
Filed: 1998-05-29
Abstract: A passive element circuit is formed by a spiral inductor, a high-dielectric-constant thin-film capacitor, a via hole, and a bonding pad. By using SrTiO3 as the high-dielectric-constant thin-film, which exhibits a dielectric constant of 200 up to a frequency of 20 GHz, it is possible to achieve a reduction of the capacitor surface area to approximately 1/30 of the area formerly required when using a SiNX (dielectric constant up to 6.5). Two high-dielectric-constant thin-film capacitors, a via hole for grounding, and a bonding pad are disposed at the center, which are surrounded by the spiral inductor. To connect the two high-dielectric-constant thin-film capacitors are joined in series,  they are  formed  on  one  high-dielectric-constant thin-film. A lead from the spiral inductor is made by a metal wire from the bondinq pad at the center.

Filed: 1997-10-23
Abstract: A water filter arrangement (10) for trapping gross pollutants flowing in a storm water system is provided in-line or at end-of-line of a storm water pipe. The arrangement comprises an inlet (14) and an inlet area (18) which directs incoming water (16) into a filter (20). The filter traps entrained gross pollutants and filtered water exits the filter via filter outlet (50). The outlet (50) and surrounding walls (58 and 57) are shaped to create a flow of filtered water which forms a water barrier which restrains the flow of water and gross pollutants from the inlet (14) to the outlet (52). The water barrier is located between the inlet (14) and the outlet (52) preferably closer to the outlet than the inlet. As the filter (20) becomes full and the flow of filtered water exiting the filter decreases the water barrier subsides. When the filter is completely blocked, the water banger completely subsides and the incoming water and gross pollutants by-pass the filter (20) and flow unrestrained without head loss from the inlet (14) to the outlet (52).

Title: Method and apparatus for awarding variable bonus awards to gaming machines over a network
Inventor: ACRES JOHN F
IPC: G07F17/32
Filed: 1999-06-16
Abstract: A method for awarding bonuses over a gaming network having a plurality of gaming machines interconnected by a network. Play is allowed to occur on the plurality of gaming machines. A bonus period is initiating for which a bonus-triggering event (e.g. a winning combination) and an initial bonus amount is determined. The reel combinations obtained from normal play over the machines are detected and compared to the winning combination determined at the start of the bonus period. A match of the combination obtained with the winning combination initiates a bonus-triggering event that results in the bonus amount being paid out to the gaming machine which had the winning combination. In a preferred embodiment, the initial bonus amount is decremented over the bonus period so that the bonus amount won is greater if the winning combination appears at the beginning of the bonus period as opposed to near the end.
