  • Patent number: 7020602
    Abstract: A domain name system includes a native language domain name registrar, which receives a native language domain name registration request. The native language domain name comprises at least one non-alphanumeric character not included in the allowable character set for domain name registration, i.e., the English alphabets A through Z, the Arabic numbers 0 through 9 and the hyphen “-”. Each of the non-alphanumeric characters is converted to a string of alphanumeric characters to produce an alphanumeric domain name comprised of strings of alphanumeric characters uniquely representing the native language domain name being requested to be registered. The resulting alphanumeric domain name is registered with the domain name registration system, and is used in the domain name/IP address entry in the domain name server (DNS).

  • Patent number: 5585547
    Abstract: An oxygen sensor probe for a boiler including a U-shaped zirconia element that is to be brought in contact with an exhaust gas in the interior of a cylindrical probe body attached to a plug and arranged together with a thermocouple in the longitudinal direction of the body. A heater for heating the element is provided around the periphery of the element and a protective filter is provided on the top portion of the body. The probe is characterized by the U-shaped zirconia element 11 being located at an upper end of the probe body 12 with its concave open portion 11' facing upwards to be contacted with the exhaust gas while its convex closed portion 11" faces downward to be confronted with the thermocouple 16.

  • Patent number: 5507189
    Abstract: Apparatus and a method for evaluating the plane strain stretch formability for thin steel sheets used in automotive bodies to provide easy evaluation of the plane strain stretch formability. The apparatus includes: a lower die and an upper die with a lock bead installed thereon. A rectangularly shaped test specimen is inserted between the upper and lower dies and, and is clamped by means of the lock bead along the circumferential edge of the test specimen, so that the material of the test specimen can be moved into the upper die. A punch is elevated to apply a stretch forming force on the test specimen, and then, the plane strain stretch formability is evaluated based on the fracture limit punch height at the instant of the fracture. The punch has a saddle-like, semi-cylindrical shape.
