  • Patent number: 10829879
    Abstract: Provided is a conductive nonwoven fabric, including a meltblown nonwoven fabric made from a melt liquid-crystal-forming wholly aromatic polyester having a melt viscosity at 310° C. of less than or equal to 20 Pa·s and satisfying (A) an average fiber diameter from 0.1 ?m to 5 ?m, (B) two or less film-like objects existing per 1 mm2 of the nonwoven fabric, (C) a breaking length in a warp direction of greater than or equal to 10 km and a breaking length in a weft direction of greater than or equal to 6 km, (D) a basis weight from 1.0 g/m2 to 15 g/m2, (E) a thickness from 5 ?m to 50 ?m, and (F) an air permeability of less than or equal to 300 cc/cm2/second, and a metal coating film formed on the meltblown nonwoven fabric.

  • Patent number: 6243073
    Abstract: A video display monitor, such as a plasma monitor, which uses a subfield method which overlaps weighted multiple binary video images in a time base for display. The stable driving of a plasma display panel may be assured and display in the 256 grey-level may be maintained although vertical synchronizing frequency of the input video signal changes. A vertical synchronizing measurement unit measures the vertical synchronizing frequency of the video signal, and a subfield number adjustment unit adjusts the number of subfields in accordance with a measured vertical synchronizing frequency. The stable driving of the plasma display panel and display in grey levels may be assured by selecting a ROM table with an output bit width equivalent to the number of subfields to be output from multiple ROM tables used for converting the number of bits in the input signal.

  • Patent number: 5322613
    Abstract: A method and apparatus are provided for marking orthodontic products. The method includes the steps of coupling the orthodontic product with the anode of a power source, placing an electrolyte in electrical contact with the cathode of the power source, and selectively exposing portions of the orthodontic product to be marked to the electrolyte. The apparatus includes a hand marker connected to the cathode of a power source. A sponge pad soaked with an electrolyte is attached to the hand marker. A workplate provided for holding the orthodontic product is coupled to the anode of the power source. A stencil is also provided to enable selective portions of the orthodontic product to be exposed to the electrolyte and thereby be marked.

  • Patent number: 4876345
    Abstract: The invention provides an indene compound represented by the following general formula (I): ##STR1## wherein R.sub.1 means a lower alkyl group, R.sub.2 and R.sub.3 denote a lower alkyl group individually or an alkylenedioxy group in combination, and R.sub.4 and R.sub.5 mean individually a substituted or unsubstituted lower alkyl or aryl group or in combination a substituted or unsubstituted piperidino, piperazinyl or homopiperazinyl group together with the adjacent nitrogen atom, with a proviso that not both R.sub.4 and R.sub.5 are a methyl group at the same time.

  • Patent number: 4826840
    Abstract: An indene compound of the general formula (I): ##STR1## in which R.sub.1 represents a lower alkyl group, R.sub.2 represents a hydrogen atom, an aryl group or lower alkyl group, R.sub.3 represents an alkyl group, and n indicates an integer of 2 or 3; or a salt thereof. The compound has very strong ameliorating or improving effects on cerebral circulation and metabolism, and thus is very useful for ameliorating, or suppressing the progress of, disturbances of brain tissues and functions.
