    摘要: An electric power steering device having a resin gear used in a speed reduction gear mechanism and the resin gear used for the device are provided. The speed reduction gear mechanism includes a driven gear that is the resin gear integrally formed by fitting a resin part having gear teeth formed on the outer peripheral surface thereof to the outside of a metal core and a drive gear meshed with the driven gear. The resin part of the resin gear is formed of a resin composition having, as a base resin, a polyamide resin containing 10 to 50% by weight of glass fiber of 5 to 9 μm in diameter, and has excellent wear resistance, durability, and dimensional stability. Grease on the meshed surfaces of the gears has such a composition that includes a thickener and 3 to 10% by weight of a wax having a melting point or softening point in the range of 70 to 130° C. in a base oil formed mainly of at least one oil selected from mineral oil, poly α-olefin oil, and alkyl polyphenyl ether.

    摘要: A method, apparatus, and program for estimating noise generation for a synchronous belt having a length and teeth spaced along the belt length. The method includes the steps of: calculating belt displacement transversely to the belt length at or near a first location at which teeth on the belt mesh with teeth on a first cooperating toothed pulley; calculating a belt fluctuation velocity by correlating the belt displacement to a time frame; and calculating a radiated sound pressure level using the belt fluctuation velocity.

    摘要: A portable electronic device having a body and a first slot formed in the body for selectively accommodating a battery and a first recording medium drive having substantially the same width as that of the battery. The first slot has a first width. The portable electronic device further has a second slot formed in the body for selectively accommodating a second recording medium drive having a width larger than that of the first recording medium drive and the battery with an attachment attached to a side surface thereof. The second slot has a second width larger than the first width of the first slot. With this configuration, the two batteries having the same shape can be simultaneously accommodated into the first and second slots, thereby allowing long-term driving of the portable electronic device.
