| 20100288736 | WELD STUD - A weld stud 10 comprises a weld flange adapted to be welded to a workpiece and a portion integrally formed with the weld flange. The flange has a surface to be welded. The surface includes a flattened annular portion of a predetermined radial width at an outer periphery thereof and a conical recess conically formed from the annular portion to the center thereof, so that only the annular portion is welded to the workpiece. | 11-18-2010 |
| 20110033260 | FASTENER ASSEMBLY FOR FASTENING A MEMBER TO WORKPIECE - A fastener assembly comprises a stud bolt including a bolt portion and a weld end to be welded to a workpiece, and a nut member to be screwed into the stud bolt. The nut member screwed into the stud bolt before welding is formed out of an electrically conductive material to allow the welding current to flow through the nut member into the stud bolt and weld the nut member to the workpiece while connected to the stud bolt. Then an attachment member is disposed on top of the workpiece, and the attachment member is fastened to the workpiece when the nut member is turned in the fastening direction. | 02-10-2011 |
| 20110278275 | ARC WELDING METHOD AND ARC WELDING APPARATUS - An arc welding apparatus welds a bracket held by a welding head to a pipe by arc welding. A hollow tubular member is provided in the bracket, which tubular member is formed in a hollow conical shape or funnel, so that the diameter thereof increases from the bracket to an open mouth therein. The open mouth of the tubular member of the bracket held by the welding head is pulled up from a condition of being in contact with the pipe, an electric arc is generated between the mouth of the tubular member and the pipe to effect melting, and the open mouth is pressed against the pipe, whereupon the bracket is welded to the pipe. | 11-17-2011 |

| 20080199794 | ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, METHOD OF MANUFACTURING ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC APPARATUS - An electrophotographic photosensitive member having excellent electrophotographic properties while being prevented from the generation of blade turn-up, a method of manufacturing the electrophotographic photosensitive member, and a process cartridge and an electrophotographic apparatus each having the electrophotographic photosensitive member are provided. The surface layer of the electrophotographic photosensitive member contains a polymer having a specific repeating structural unit. | 08-21-2008 |
| 20090124040 | FIELD EFFECT TRANSISTOR, METHOD OF PRODUCING THE SAME, AND METHOD OF PRODUCING LAMINATED MEMBER - There is provided a field effect transistor having an organic semiconductor layer, including: an organic semiconductor layer containing at least porphyrin; and a layer composed of at least a polysiloxane compound, the layer being laminated on the organic semiconductor layer so as to be in intimate contact with the organic semiconductor layer. As a result, there can be provided a field effect transistor which enables an organic semiconductor layer having high crystallinity and high orientation to be formed and which exhibits a high mobility. | 05-14-2009 |
| 20090180800 | ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, METHOD OF MANUFACTURING ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC APPARATUS - An electrophotographic photosensitive member having excellent electrophotographic properties while being prevented from the generation of blade turn-up, a method of manufacturing the electrophotographic photosensitive member, and a process cartridge and an electrophotographic apparatus each having the electrophotographic photosensitive member are provided. The surface layer of the electrophotographic photosensitive member contains a polymer having a specific repeating structural unit. | 07-16-2009 |
| 20090186490 | ORGANIC SEMICONDUCTOR DEVICE, FIELD-EFFECT TRANSISTOR, AND THEIR MANUFACTURING METHODS - An organic semiconductor device is provided which includes an organic semiconductor layer and an insulating layer. The insulating layer is made of a cured material formed from a composition containing a resin and a crosslinking agent. The resin contains an organic resin having a hydroxyl group. The crosslinking agent contains a compound having at least two crosslinking groups. At least one of the crosslinking groups is a methylol group or an NH group. The composition contains the crosslinking agent in the range of 15 to 45 percent by weight relative to 100 parts by weight in total of the resin and the crosslinking agent. | 07-23-2009 |
| 20090263933 | FIELD EFFECT TRANSISTOR AND METHOD OF PRODUCING SAME - A field effect transistor is provided which comprises an organic semiconductor layer comprising a compound having a monobenzoporphyrin skeleton represented by the general formula (1): | 10-22-2009 |
