  • Patent number: 8221920
    Abstract: A separator for a valve regulated lead-acid battery which comprises a paper sheet where very fine glass fiber is a main component, which has a piercing strength (puncture strength) of 4.5 N/mm or more and a tensile strength of 7.0 N/10 mm2 or more. The paper sheet is made by blending 80 to 90% by weight of glass fiber having 1.5 ?m or less average fiber size, 5 to 10% by weight of single-material monofilament-form thermally non-adhesive organic fiber (non-heat-bondable organic fiber) and 5 to 10% by weight of single-material monofilament-form thermally adhesive organic fiber (heat-bondable organic fiber) comprising the same kind of material as in the thermally non-adhesive organic fiber in a wet papermaking process whereupon the fiber materials are bonded each other by thermal fusion of the thermally adhesive organic fiber whereby a coat (film) by melting of the organic fiber is not substantially formed on the surface of the glass fiber.

  • Patent number: 7486409
    Abstract: In a sensor head, parallel rays or approximately parallel rays are generated by a pair of condenser lenses that reciprocate according to vibrations of a collimate lens and a tuning fork, and go out from a light port. To the light port, a lens holder in which an objective lens is supported is detachably attached. The light from the light port is processed to measurement beams that are condensed by the objective lens to a predetermined position.

  • Patent number: 7337082
    Abstract: A measurement instrument includes a measurement value acquiring portion for acquiring a measurement value in a predetermined period, and a measurement timing acquiring portion for acquiring measurement timing information. The measurement timing information is a measurement start timing, and the measurement timing information is added to the measurement value acquired in a predetermined period, corresponding to elapsed timing information which is calculated from the measurement period, based on the measurement start timing. In addition, a plurality of the measurement values added by the measurement timing information are digitally outputted collectively.

  • Patent number: 7191087
    Abstract: A sensor controller is disclosed which transmits large-capacity data such as waveform data and image data within a short time (in rapid cycles, for example) and makes possible various collaborative operations using the transmitted data. A control unit includes a programmable logic circuit and a CPU to control the operation of the sensor controller. A unit connector can be used to connect other sensor controllers. An inter-unit path constitutes a signal transmission path between the control unit and the unit connector and includes a sensing data transmission path between the programmable logic circuit and the unit connector. In the case where another sensor controller is connected to the unit connector, the sensing data can be transmitted between the programmable logic circuit of the local sensor controller and the programmable logic circuit of the particular another sensor controller.
