摘要： PROBLEM TO BE SOLVED: To provide a sliding component having improved durability and wear resistance.
SOLUTION: A sliding portion 33 on a balance shaft 25 of a balance has a Cr coating 31 and a DLC coating 32. The DLC coating 32 is partially removed where a lubricant sump 35 is formed. The lubricant sump 35 is formed so that the area ratio thereof to the surface of the sliding portion 33 is greater at the middle stage of the sliding portion 33 where the speed of a connection member 22 relative to the balance shaft 25 is higher and so that the area ratio thereof to the surface of the sliding portion 33 is smaller at both upper and lower ends of the balance shaft 25 where the pressure of the connection member 22 on the balance shaft 25 is greater. Thus, a great amount of lubricant resides in the middle stage of the sliding portion 33 requiring a great amount of lubricant. Bearing pressure that the sliding portion 33 receives from the connection member 22 is reduced at both upper and lower ends with the DLC coating 32 left much, where great pressure exists, to improve durability and wear resistance.

摘要翻译：要解决的问题：提供具有改善的耐久性和耐磨性的滑动部件。解决方案：天平的平衡轴25上的滑动部分33具有Cr涂层31和DLC涂层32.在形成润滑油槽35的情况下，DLC涂层32被部分地去除。在滑动部33的中间阶段，连接部件22相对于平衡轴25的速度越高，润滑剂油槽35的面积比越大，滑动部33的表面的面积比越大，其平衡轴25上的连接构件22的压力较大的平衡轴25的上端和下端的滑动部33的表面的面积比都较小。因此，在需要大量润滑剂的滑动部33的中间阶段，存在大量的润滑剂。滑动部分33从连接构件22接收的承受压力在DLC涂层32处于较大压力存在的情况下在上端和下端都减小，以提高耐久性和耐磨性。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a sewing machine improving the durability by greatly improving the sliding performance and abrasion resistance between relatively operating a first member and a second member.
SOLUTION: This sewing machine is so constituted that a DLC film is formed on the surface of a thread take-up shaft 24, or the first member, and an aluminum bush 33 is press-fitted and fixed in a bearing hole 31 of a thread take-up bearing 26, or the second member, for supporting the thread take-up shaft 24. The thread take-up shaft 24 is applied with grease, and the grease is formed by using DOS (dioctyl sebacate), or synthetic oil, as base oil, 16 wt.% of Li soap as thickener, and 5 wt.% of ZnDTp (zinc dithiophosphates) and MoDTC (molybdenum dithiocarbamate) as additives.

摘要： PROBLEM TO BE SOLVED: To enable a superior sewing to be carried out without producing any poor sewing or reduction in quality of round-shaped raised portion or the like even in the case that a normal usual cloth is applied as an item to be sawn and a soft and expandable raw material cloth such as a micro-fiber cloth is applied.
SOLUTION: A movable needle thread feeding member 8 arranged at a sewing machine arm segment 1 so as to be reciprocated and oscillated in a vertical direction under a synchronous operation with a vertical reciprocating motion of a needle rod 3 and a needle 5, to cause a needle thread 9 passed through a specified needle thread path 13 and supplied to be descended and guided toward the needle 5 is provided with a needle thread guiding segment 8a having a third needle thread feeding hole 8C for feeding out and guiding a needle thread segment 9a between a first needle thread feeding hole 8A formed at its extremity end and a second needle thread feeding hole 8B formed at a substantial intermediate portion in a longitudinal direction under a state in which it is bent substantially in a V-shape in a downward direction.

摘要： PROBLEM TO BE SOLVED: To reduce the length of a needle thread from a hole of a needle to the needle thread end before the start of sewing. SOLUTION: This sewing machine 1 includes a thread tension device 17 for applying pressing force to the needle thread, a needle thread handling member 29 for handling the needle thread guided from the thread tension device 17, air cylinders 26, 27 for moving the needle thread handling member 29 from the foremost position P10 through the middle position P30 to the last position P20, a needle thread cutting knife 14 for cutting the needle thread, and a control device 50 for controlling the air cylinders 26, 27. The needle thread is guided from the needle thread handling member 29 to a needle thread take-up lever 18 to finally reach a thread passing hole 6a of a needle 6. Immediately before the start of sewing, the needle thread handling member 29 is moved from the foremost position P10 to the last position P20. After the end of sewing, the needle thread handling member 29 is moved from the last position P20 to the middle position P30. After that, the pressing force to the needle thread is increased by the thread tension device 17. Subsequently, the needle thread handling member 29 is moved from the middle position P30 to the foremost position P10. COPYRIGHT: (C)2003,JPO
