Title: Consumable electrode electroslag refining feed systems and methods
Inventor: KNUDSEN BRUCE ALAN
IPC: C22B9/18
Filed: 2000-05-02
Granted: 2003-08-11
Abstract: A consumable electrode feed system for a refining system provides consumable electrodes to a refining system. The consumable electrode feed system comprises a side feed device that feeds consumable electrodes to a refining system in a first direction; a refining feed device that feeds consumable electrodes to a refining system in a second direction, in which the second direction being generally orthogonal to the first direction; and a connection system for connecting fed consumable electrodes to each other. The consumable electrode feed system allows for a predetermined amount of a consumable electrode to be refined in the refining system, and can position another consumable electrode above a previously fed consumable electrode. The connecting system then can connect a fed consumable electrode to a previously fed consumable electrode thus avoiding refining operation.

Title: Integrated rolling type base isolation device enclosing trigger mechanism
Inventor: WATANABE SHINICHI
IPC: E04B1/98
Filed: 2000-10-03
Granted: 2002-05-21
Abstract: This invention provides an integrated rolling type base isolation device enclosing trigger mechanism which will provide isolation function for structures in violent earthquake and prevent structures from being shaken by wind pressures and minor earthquakes. In the trigger mechanism of this device, a rolling ball 1 enclosed in a ball housing 7 normally rests on a circular hole 3 in the center of a rolling conical surface 2 and keeps a stable condition. When the rolling ball 1 moves out of the circular hole 3 in a strong earthquake, the rolling ball 1 is resiliently raised by a cam mechanism and the circular hole 3 is restored to its original state since a circular conical floor 4 enclosed in the lower portion of the mechanism and having a ladder-shaped cam at its lower end meshes with a drum ladder-shaped cam 5 containing a coil spring 6 there below and tending at all times to rotate in the direction indicated by the arrow. Therefore, the rolling ball 1 freely rolls within the rolling conical surface 2 and produces a base isolating effect. The rolling ball 1, however, is kept stationary against wind pressure and the shaking of a minor earthquake of such magnitude that the rolling ball 1 does not move out of the circular hole 3. An operating lever 8 is restored to its normal condition.

Title: Acoustic touchscreen having waveguided reflector arrays
Inventor: GOMES PAULO IRULEGUI
IPC: G06F3/033
Filed: 2001-05-16
Granted: 2003-05-11
Abstract: An acoustic touchscreen (1a) has transmitting transducers (23a, 23b) for generating acoustic signals which are deflected across a touch-sensitive area (2) by an array 13 of partially acoustically reflective elements 14. A touch on the touch-sensitive area causes a perturbation in the acoustic signals. After traversing the touch-sensitive area, the acoustic signals are redirected by another array 13 of partially acoustically reflective elements 14, towards receiving transducers (26a, 26b), where the signals (and any perturbations) are sensed. To accommodate touchscreens having narrow border regions (15a), the acoustic signals are propagated across the border regions using acoustic waveguides (18). The waveguide confines the acoustics signals to traveling along a narrow path width, but yet permit them to be deflected across the touch-sensitive area. In this manner, the transducers and reflective elements can in turn be of narrower construction and can fit within narrow border regions.

Abstract: An interface circuit performs supply/reception of data with a register instead of supply/reception of data with DRAM when an area specified by an address signal is a logic control area. Data signals in the case are a control command for a logic circuit held in a register and input data to be processed. The logic circuit takes charge of a critical path in processing time such as cryptographic processing and image processing. A processing result is held in the register. The register circuit switches between storage data stored in DRAM and data given from a terminal group to select data to be processed according to a control signal.
