Title: Earring
Inventor: TAKUMA KENJI
IPC: A44C7/00
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To eliminate drop of a pinching force even through repetitive operation of opening and closing by performing the tightening while a hard nature washer is interposed between mounting legs for engaging a main ornament piece and a pinching member and a mounting base part. SOLUTION: A main ornament piece 1 is equipped rigidly with a pair of mounting legs 3 and 4, and in such a way as confronting them, an aux. ornament piece 2 is equipped rigidly with a base 5, which is fitted between the mounting legs 3 and 4. A pin 8 is inserted between through holes 6 and 7 provided in them, and this part is tightened. Between the legs 3 and 4 and the base 5, a stainless steel washer 9 having a higher hardness than the material K-18 of the two members is interposed to perform the tightening. When this is used to open and close the main 1 and aux. ornament pieces 2 of the earring, the legs 3 and 4 and the base 5 will never touch directly, and there is no more risk that two comparatively soft members contact with each other. This allows avoiding wear and deformation to permit the resultant earring to sustain a long period of service.

Filed: 1988-04-30
Abstract: PURPOSE:To enable the optimum tracking by comparing a regenerative signal at the time when the regenerative signal exceeds its peak value with a regenerative signal prior to exceeding the peak value in level, taking the larger one as reference value and regarding a head position of exceeding this reference value as a track position. CONSTITUTION:A magnetic head 1 is moved by a moving head moving direction setting means 5 of a control means 3 and a magnetic head moving means 2 in the direction of increasing the regenerative signal level according to a detecting means 4. Then, the peak of the regenerative signal is discriminated by a 1st discriminating means 6, and the larger signal in level between the regenerative signals at the time of exceeding the peak position and prior to the time of exceeding this position is automatically decided as the reference value by a reference value setting means 7. When the regenerative output by the means 4 is larger in its level than this reference value, the head 1 is discriminated to be in the track position by a 2nd discriminating means 8, and since the reference value is not fixedly settled beforehand, the optimum position tracking can thus be performed.
