Abstract: The process makes possible lubrication of bearings, in particular of the antifriction type for high rotation speeds by injection of a pressurized gas current that carries the nebulized lubricating fluid along a closed circuit without communication with the outside. 
     This fluid is injected into the friction zones of bearings (3-3′) which lubricates by rapidly going through them without causing stagnations of the lubricant, and being carried, without being able to go out into the outside environment, by collectors (4, 4′) and feed ducts (5) into the liquid contained in a collection tank (6), where the fluid, which is separated from the carrier gas, can then be separated from the liquid by decanting or similar processes and optionally recycled.

Inventor: SHINBORI HIROICHI
IPC: G06F3/033
Filed: 1990-03-22
Abstract: A device for determining position coordinates of points on a surface, has a tablet containing plural number of equally spaced driver windings and plural number of equally spaced sense windings. Each driver winding has a pair of parallel conductors laid in X-­direction, and each sense winding has a pair of parallel conductors laid in Y-direction. A current is generated in a cursor coil by the voltage induced from the current in a nearby situated driver winding. This current in the cursor coil induces a voltage in a nearby situated sense winding. The X-position of a sense winding in which a maximum voltage is induced, and the Y-position of a driver winding which induces a maximum voltage in the cursor coil, determine the position coordinates of the cursor on the tablet. Auxiliary sense windings are supplemented to the tablet. Induced voltages on these auxiliary sense windings determine the Y-position of the cursor in disregard to its X-position, and reduce the overall time required for position determination.

Abstract: An expert system is used to perform surveil­lance, diagnosis and prognosis of a plant such as a nuclear reactor used in electrical power generation. The expert system uses one of real time actual plant data, previously stored actual plant data or simulated plant data as plant condition data to perform an evaluation of operating conditions in the plant. When real time actual plant data is used, a data acquisition system supplies the plant condition data. The expert system accesses the plant condition data, regardless of its source, periodi­cally as a surveillance frame is triggered by the rules in the root frame controlling the expert system. Other frames in the expert system perform diagnosis and prognosis of the plant condition.

Abstract: An integrated circuit having an analog-to-digital converter (101) includes built-in self-test (BIST) circuitry. The BIST circuitry checks for monotonicity (104), and typically also that all possible codes are present (105), by applying a ramp voltage (102) to the A/D input, while a state machine (104,105) monitors the output. The state machine can check to ensure that the output increases by only one least significant bit (LSB) each time the output changes. A counter may be checked at the end of the test, to ensure that all the possible codes are obtained. The BIST circuitry may be activated, and the results monitored, through package terminals after the chip is packaged, thereby allowing for boundary scan testing. The inventive technique may be used to save testing costs during manufacture. In addition, system diagnostics in the field can become more cost effective.
