  • Electronic apparatus in which functioning of a microcomputer is monitored by another microcomputer to detect abnormal operation
    Patent number: 8091014
    Abstract: In an electronic apparatus, a first microcomputer is monitored by a second microcomputer, which periodically transmits data relating to a main function to the first microcomputer to be processed. The first microcomputer periodically updates a variable value, performs a predetermined calculation operation whose final result should be a specific fixed value, adds that final result to the updated variable value to obtain a sum value, and transmits the sum value and updated variable value concurrently to the second microcomputer. The second microcomputer determines that the first microcomputer is operating abnormally if the difference between the received sum value and variable value is not equal to the specific fixed value.

  • Electronic apparatus capable of outputting data in predetermined timing regardless of contents of input data
    Patent number: 7814358
    Abstract: Simply constituted electronic apparatus that can definitely output an outputted data after predetermined length of time from a time when an inputted data processing is started, even if data processing time of the inputted data varies with the contents of the data.

  • Friction material
    Publication number: 20040241429
    Abstract: A friction material having a good balance of properties is made by molding and curing a composition which contains a fibrous base, a binder and a filler, and includes a specific combined amount of at least three types of metal oxide having Mohs hardnesses of 4 to 6.5. The friction material suppresses low-frequency noise generation, minimizes rotor and disc pad wear, and has a high and stable coefficient of friction at high speeds.

  • Non-asbestos friction materials
    Publication number: 20020132877
    Abstract: A non-asbestos friction material is obtained by molding and curing a composition comprising a fibrous base other than asbestos, a binder and a filler. The fibrous base is composed in part of 1-15 vol % of inorganic fibers having a Mohs hardness of less than 4.5 and the filler includes 0.5-15 vol % of cashew dust, based on the overall composition. The friction material undergoes little wear during high-speed braking, has an excellent heat resistance, stable braking effectiveness and good strength, and generates little undesirable brake noise, especially when used as brake linings in drum brakes.
