    • PROBLEM TO BE SOLVED: To provide a toothbrush for tooth brushing practice by which a member of dental staff such as a dentist or a dental hygienist can correctly and securely instruct a patient or a person who unsuitably uses a toothbrush in a method to brush teeth correctly with bristle points moving "finely and little by little" and everyone can practice correct tooth brushing by oneself at a home, a school, a working place, etc.
      SOLUTION: This toothbrush for tooth brushing practice has a pendulum device set integrally in a void bored in prescribed length almost in parallel along the long shaft of the grip part of a toothbrush or set on the grip part of a toothbrush via an engaging member. The pendulum device comprises a space surrounded by a prescribed member so as to have prescribed length, permanent magnet members placed on both end parts in the longitudinal direction of the space, respectively, and a moving body which has a permanent magnet placed on at least a constituting member longitudinally and movably housed in the space so as to usually repulse against magnetic force of the permanent magnet members.

    • 要解决的问题:提供一种用于牙齿刷牙实践的牙刷,通过该牙刷牙科工作人员(例如牙医或牙科卫生师)的成员可以在方法中正确且可靠地指导患者或不适合使用牙刷的人 刷牙正确,刷毛点“精细一点点”移动,每个人都可以在家里,学校,工作场所等自己练习正确的牙刷。

      解决方案:这种牙刷刷牙练习有一个摆锤 装置一体地设置在沿着牙刷的把手部分的长轴几乎平行地以规定长度钻孔的空隙中,或者经由接合构件设置在牙刷的把持部分上。 摆锤装置包括分别由具有规定长度的规定部件包围的空间,分别设置在该空间的长度方向的两端部上的永久磁铁部件和至少具有永久磁铁的永磁体的移动体 构成构件纵向和可移动地容纳在该空间中,以便通常抵抗永磁体构件的磁力。 版权所有(C)2005,JPO&NCIPI

    • A spring wire with hardness of 50 to 56 HRC is subjected to first and second shot peening processes within a warm working temperature range of 150 to 350° C. In the first shot peening process, the first shot of a shot size of 1.0 mm or more is used. In the second shot peening process, the second shot smaller in shot size than the first shot is used. Through these shot peening processes, compressive residual stress is imparted to the spring wire. The spring wire includes a residual stress increase part, residual stress peak part, and residual stress decrease part. In the residual stress decrease part, a part including the compressive residual stress magnitude of which is equivalent to the magnitude of the compressive residual stress at the surface of the spring wire exists at a position at a depth exceeding the permissible pit depth.
    • 硬度为50〜56HRC的弹簧丝在150〜350℃的温暖​​工作温度范围内进行第一次和第二次喷丸硬化处理。在第一次喷丸硬化处理中,第一次喷丸大小为1.0mm, 更多使用。 在第二次喷丸硬化处理中,使用比第一次投篮更小的投篮尺寸。 通过这些喷丸硬化处理,赋予弹簧丝压缩残余应力。 弹簧丝包括残余应力增加部分,残余应力峰部分和残余应力减少部分。 在残余应力减少部分中,包括其压缩残余应力大小等于在弹簧丝表面处的压缩残余应力的大小的部分存在于超过允许凹坑深度的深度的位置处。
