Patent number: 7146596Abstract: An integrated circuit chip having a contact layer that includes a plurality of Vdd, Vddx, ground and I/O contacts arranged in a generally radial pattern having diagonal and major axis symmetry and generally defining four quadrants. A multilayer X-Y power grid is located beneath the contact layer. A wiring layer is interposed between the contact layer and power grid to provide a well-behaved electrical transition between the generally radial Vdd, Vddx and ground contacts and the rectangular X-Y power grid. The interposed wiring layer includes concentric square rings of Vdd, Vddx and ground wires located alternatingly with one another. The Vddx wires are discontinuous between adjacent quadrants so that the magnitude of Vddx may be different in each quadrant of the chip if desired.Type: GrantFiled: August 29, 2003Date of Patent: December 5, 2006Assignee: International Business Machines CorporationInventors: Thomas R. Bednar, Timothy W. Budell, Patrick H. Buffet, Alain Caron, James V. Crain, Jr., Douglas W. Kemerer, Donald S. Kent, Esmaeil Rahmati

Patent number: 7096436Abstract: Macro design techniques are disclosed for facilitating subsequent stage wiring across the macro. Whitespace areas within the macro are rearranged to accommodate the wiring. The rearrangement may take the form of physical rearrangement of the whitespace areas into routing tracks extending from one side of the macro to another; shielding using, for example, macro power bussing and/or macro wiring; routing power busses to the rearranged whitespace; and/or inserting active circuits with pins accessible to the wiring. In a preferred embodiment, active circuits are placed into rearranged macro whitespace during the design of subsequent stages. The rearrangement of the whitespace facilitates the wiring across the macro so that slew rate and path delay requirements of the subsequent stage wiring can be maintained, without excessive buffering or rerouting of wiring.Type: GrantFiled: September 21, 2004Date of Patent: August 22, 2006Assignee: International Business Machines CorporationInventors: Thomas R. Bednar, Paul E. Dunn, Scott W. Gould, Jeannie H. Panner, Paul S. Zuchowski

Patent number: 6880223Abstract: A grease slinger, power tool and method of assembling a power tool. The power tool includes a housing, a motor supported in the housing and including a rotatable shaft extending along an axis, a gear case connected to the housing, a flange between the housing and the gear case having a first side and a second side and defining an opening extending between the first side and the second side, a drive mechanism supported by the gear case and drivingly engaging the motor shaft, and a grease slinger. The grease slinger includes a body supportable on the shaft for rotation with the shaft relative to the flange. The body has a first face providing a grease-slinging surface and a second face facing the first side of the flange. The second face includes an annular side wall defining an annular channel.
