20130206758 | FUEL FILLER PIPE - A fuel filler pipe offering high anticorrosion performance and high fabrication accuracy is provided. Specifically, a tubular fuel filler pipe body | 08-15-2013 |
20130111966 | METHOD FOR FORMING STEEL SHEET BY HOT PRESSING - Consumed energy is minimized to reduce running cost. Final formed products of uniform quality are successively obtained. High productivity is provided. A primary forming step of obtaining a primary formed product by plastically working a heated steel sheet with a primary forming die set for a predetermined time period, a secondary forming step of machining the primary formed product with the secondary forming die set for a predetermined time period to obtain a secondary formed product, and a hardening step of allowing a cooling die set placed in a hydraulic press controlled by a servomotor to hold the secondary formed product under pressure for a longer time period than the time period of each of the primary and secondary forming steps to obtain a hardened final formed product are successively performed in sequence. The hardening step is performed independently without coordinating with the primary and secondary forming steps. | 05-09-2013 |
20130032243 | FUEL VAPOR HANDLING SYSTEM FOR AUTOMOTIVE FUEL TANK - Fuel vapor is prevented from leaking to the outside during refueling, and even when an air space is formed in an upper portion of a fuel filler pipe, a diagnosis of leakage of fuel vapor can be performed with good accuracy. | 02-07-2013 |
20120200695 | ELECTRODE INSPECTION APPARATUS FOR SPOT WELDING - An electrode inspection apparatus for spot welding is provided for precisely measuring diameters of a tip of an electrode without reducing availability ratio in a production line, and is particularly useful when inspecting a weld gun having electrodes with a narrow distance therebetween. | 08-09-2012 |
