Filed: 1989-05-25
Abstract: PURPOSE:To restore a tracking frequency to a center frequency at a controlled speed by adding a phase correction obtained at an integration means and a counter output and using the sum with an AC phase setting value. CONSTITUTION:A difference of phase between a 3-phase input signal converted into a biphase signal at a 3-phase/2-phase conversion means 10 and a feedback signal is detected by a phase difference detection means 11. Then a pulse generating means 13 generates a pulse proportional to a phase difference and the pulse is counted by a counter 14. Then the frequency of a 3-phase input signal is detected by a frequency detection means based on the count and the frequency correction returning the frequency to the center frequency in comparison with an upper/lower limit value is calculated by a correction calculation means 17 and the frequency correction is integrated by an integration means 18 to obtain a phase correction. Moreover, the phase correction and an output of the counter 14 are added by an adder means 19 and the sum is an AC phase setting value. Thus, even in the case of input interrupt, the tracking frequency is restored to the center frequency at a controlled speed.

Title: Paddle holder for pivot assisting fibrillation remover
Inventor: JIYONASAN ENU ANDORIYUUSU
IPC: A61N1/39
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To enable the paddle to be retained in the retainer assembly with a strong retaining force and to be pulled out from the retainer assembly with a weak force, by including a releasing means such that the paddle can be pulled out from the retainer assembly by exerting, on the handles, a pull less than the retaining force of the retainer. SOLUTION: When two handles 23 are pulled by a force in the direction of the arrow Fw, a back plate 51 is pivoted around the pivot axis due to the moment exerted by the pivotal mount of a lip 59 and the back plate 51 and Fw×Y. The inner side of a paddle base 21 applies a forward force to a bracket to push the inner edge of the back plate 51 forward from the back wall 37. A tub 56 which is not restricted by the back wall 37 deflects into a recess 39. The upper side portion of a fastener 67 keeps stationary on the outer edge of the back wall 37. The flexibility of the tub 56 allows the lip 59 to be pulled to a point where the front edge of the lip is on the same plane with the side portion. Thus the lip 59 is released from the upper confinement with the outer edge of a base plate 21, the paddle 19 can be pulled out freely.
