  • Patent number: 6317917
    Abstract: An improved structure paper mop board facing that is adhesion mounted at the ground level aspect and, furthermore, efficiently removes by absorption dust on floors. The paper mop board facing is adhesively attached to the floor section of the mop board and consists of a number of a pliable and, furthermore, disconnected and cross-laterally arrayed three-dimensional pattern of diagonal ridges on a plane surface, with the lower plane surface of the three-dimensional pattern lined with a non-weave fabric that provides for the wiping of floors. As such, when the said three-dimensional pattern of the paper mop is swabbed against a floor surface, the three-dimensional pattern on the underside of the paper mop board facing becomes deformed from the applied pressure and scours the floor, while crevices interspersed within the three-dimensional pattern of the paper mop board facing entrap dust.

  • Patent number: 6311994
    Abstract: The present invention relates to a skateboard-like exerciser primarily comprising a blocking connecting rod interposed between a braking unit behind the deck and the main frame. When the blocking connecting rod is not touched first, the braking unit can't be pressed for reaching an expected braking effect. Consequently, a danger can be avoided when the braking plate is unintentionally pressed. Moreover, a resilient body is disposed at a proper position between the deck and the main frame, and the main frame contains a plurality of locking holes so that the locking position of the resilient body can be adjusted backwards or forwards. In addition to obtaining the cushioning effect, the touch sensitivity of the braking plate is synchronically adjustable.

  • Patent number: 6313054
    Abstract: The present invention provides a silicon nitride sintered body having characteristics such as excellent wear resistance, a method for manufacturing the sintered body, and a cutting insert formed thereof. The silicon nitride sintered body is formed of a polycrystalline sintered body of predominantly &bgr;-Si3N4, wherein the oxygen content is 1.2-1.5 wt. %. The method for manufacturing the silicon nitride sintered body includes the following steps: adding an organic binder to a composition containing silicon nitride as an essential component and exhibiting a theoretical oxygen content of 2.0-3.0 wt. %; heating to remove the binder; introducing an oxygen-containing gas so as to control the carbon content to 0.10-0.60 wt. %; and sintering a resultant compact in an nitrogen atmosphere to control the oxygen content to 1.2-1.5 wt. %. The cutting insert of the present invention has excellent wear resistance.

  • Patent number: 6309098
    Abstract: A contactless-smart-IC-card receive and read-write mechanism for an on-street parking meter. The mechanism includes a nested cartridge set consisting of a card read-write unit and a card receiver. The card read-write unit further includes an outer case having an induction coil and a circuit board attached to one outer side of the outer case. The card receiver is removably nested in the outer case for an IC card to insert thereinto. The circuit board has different circuits provided thereon for controlling power supply to correctly complete card reading and overwriting. A detecting switch is mounted on the outer case to detect the existence of the IC card in the card receiver. Only when a correct IC card in the receiver is detected will a high frequency power supply circuit be actuated for the card read-write unit to read and overwrite data or amount stored in the IC card. The card read-write unit is not affected by external dust or rainwater to cause error operation.
