  • Patent number: 11480924
    Abstract: An escape lever suppresses energy loss and provides strong resistance to external shocks. An escape lever has a pallet fork; a pallet formed in unison with the pallet fork for engaging the escape wheel; and a pallet staff that is a pivot of the pallet fork and passes through the pallet fork. The pallet has a locking surface that the locking corner of the escape wheel contacts in the unlocking period when the escape wheel is released by the pallet and freed to move. The locking surface is shaped so that the draw angle formed by a normal to the contact point with the locking corner of the escape wheel, and a line through the contact point and the axis of the pallet staff, remains constant during the unlocking period.

  • Patent number: 10693362
    Abstract: A switching power supply includes an insulated transformer, a full-bridge circuit which converts input DC power into AC power and outputs the AC power to a primary-side coil, an output circuit which converts AC power input from secondary-side coils into DC power and outputs the DC power, and a control circuit which controls the full-bridge circuit by using a phase shift method based on voltage output by the output circuit. When a measured value of the amount of phase shift determined from at least one of the voltage and current output by the output circuit is smaller than a theoretical value of the amount of phase shift corresponding to the switching power supply operating in a continuous current mode, the control circuit prolongs dead time used in the full-bridge circuit in accordance with the difference between the measured value and the theoretical value.
