  • Patent number: 5582623
    Abstract: Disclosed are methods of making solid-phase active-sulfur-based composite electrodes. The method begins with a step of combining the electrode components (including an electrochemically active material, an electronic conductor, and an ionic conductor) in a slurry. Next, the slurry is homogenized such that the electrode components are well mixed and free of agglomerates. Very soon thereafter, before the electrode components have settled or separated to any significant degree, the slurry is coated on a substrate to form a thin film. Finally, the coated film is dried to form the electrode in such a manner that the electrode components do not significantly redistribute.

  • Patent number: 5583542
    Abstract: A method for deleting objects displayed on the screen of a display assembly of a pointer based computer system is described. The method includes the steps of detecting a pointer created stroke and processing the stroke for gesture recognition. Thereafter, the processed stroke is checked to determine whether it meets the path definition requirements of a scrub gesture. In another step, a determination is made as to whether an object displayed on the screen has been selected. If an object is selected and the processed stroke meets the requirements of a scrub gesture, the selected object is deleted. In a preferred embodiment of the invention, the selected object determining step includes the substep of determining whether any objects were preselected at the time the scrub gesture was made. When no suitable objects are preselected, a determination is made as to whether the scrub gesture substantially overlaps a displayed object. If a displayed object is substantially overlapped, it is selected for deletion.

  • Patent number: 5579992
    Abstract: In a combination faucet device (10) according to the invention, a movable valve member (160) slidingly moves relative to a main casing (30) to change a mixing ratio of high-temperature water supplied from a hot water port (116) to low-temperature water supplied from a cold water port (106). The movable valve member (160) is pressed by a temperature sensitive spring (130) in a first direction while being pressed by a bias spring (150) in a second direction opposite to the first direction. The temperature sensitive spring (130) is exposed to water mixture and varies its spring constant according to the temperature of the water mixture. The temperature sensitive spring (130) accordingly moves the movable valve member (160) in a direction for decreasing the ratio of the high-temperature water to a certain position where the spring force of the temperature sensitive spring (130) balances with the spring force of the bias spring (150), thus allowing water mixture adjusted to a target.

  • Patent number: 5572712
    Abstract: A behavioral synthesis method for making integrated circuits with built-in self-test (BIST). Base specifications describing base functionality and BIST specifications describing BIST functionality are developed. The base specifications are described in a hardware description language (HDL) to create a base HDL which is input into a digital computer system. Utilizing both the base specifications and the BIST specifications, a BIST HDL is created on the digital computer system. A netlist is synthesized on the computer system from both the base HDL and the BIST HDL. Thereafter, a digital integrated circuit is produced as specified by the netlist. An advantage of the present invention is the description of BIST circuitry at the HDL level of abstraction instead of at the netlist level. By automatically generating BIST HDL given BIST specifications and base circuit specifications, a circuit designer is relieved of the complications of gate level manipulations to insert a BIST description into a netlist.
