  • Patent number: 6840236
    Abstract: To accurately detect occurrence of erroneous detection of a crank pulse associated with dropout of a crank pulse or occurrence of noise. A cogless section is provided in cogs provided on an outer periphery of a crankshaft for transmitting a crank pulse. Occurrence of erroneous detection of a crank pulse is detected through use of an instantaneous rotational speed of the crankshaft computed from a crank pulse assigned to the cogless section and crank pulses assigned to cogs before and after the cogless section. When too few crank pulses are detected, a rapid increases arises in the instantaneous rotational speed of the crankshaft computed from the crank pulses after occurrence of a rapid decrease. The number of detected cramp pulses—which are fewer than the original crank pulses—is detected from the number of crank pulses existing between occurrence of a rapid decrease and occurrence of a rapid increase.

  • Publication number: 20030187834
    Abstract: A document search method for extracting document information similar in content to given document information, from a document database with high accuracy and efficiency. A first document database is searched based on a search query which is input by a user. First document information extracted by the search of the first document database is formatted into a format of a second document database. The second document database is searched by using the formatted first document information. Second document information which is similar in content to the formatted first document information is extracted. A degree of similarity between the formatted first document information and the second document information is calculated. The calculated degree of similarity is corrected in accordance with a condition of correction which is preset. The first and second document information and the corrected degree of similarity are output.

  • Patent number: 6339377
    Abstract: An article surveillance security system with self-alarm operates at 6 through 10 MHz as a central frequency, receives a swept low level radio wave within ±5 through 15% from the central frequency, and sounds the alarm. It includes a tuning circuit (1) tuning to the central frequency, and a differential amplifier (2) for amplifying and detecting the output of the tuning circuit. The load resistance (R1) of the differential amplifier is set to 3 through 5 M&OHgr;, and the operating current of the differential amplifier is set to 3 &mgr;A or less. The base-emitter of the amplification/detection transistor (Tr1) of the differential amplifier are connected to the base-emitter of another diode-connected transistor (Tr2) to stabilize a bias drift by temperature. Thus, a receiving circuit of an article surveillance security system with self-alarm (tag) is realized with ability having a power supply of approximately four-year durability, stably operating with a very low level radio wave at 8.

  • Patent number: 6156676
    Abstract: The present invention provides apparatus and a process for efficiently removing particles generated during a laser marking of the semiconductor wafer substrate, thereby improving the yield. The process of the invention for marking a semiconductor wafer substrate by a beam of laser radiation comprises the steps of flowing a gas over a marking region at a predetermined flow rate and removing the gas from the marking region at the same predetermined flow rate, thereby generating a gas flow having a predetermined flow rate over and adjacent the marking region so that particles produced from the semiconductor wafer substrate while it is being marked will be removed. In a preferred embodiment, the semiconductor wafer substrate may be mounted with its upper surface to be marked directed downwardly while the laser marking beam is directed upwardly to the substrate.
