  • Patent number: 7552941
    Abstract: The airbag apparatus includes a case for housing and holding an airbag and an inflator. The case includes a vent opening for releasing inflation gas filled inside the airbag and a lid operated by an actuator for closing and opening the vent opening. The lid is pivotally supported at a periphery of the vent opening for rotation about its rotary shaft disposed across the vent opening, and includes an outward-opening area adapted to rotate outward of the case and an inward-opening area adapted to rotate inward of the case, with a border of the outward-opening area and inward-opening area disposed on the rotary shaft. A sliding element is connected to the actuator for holding the lid to keep the vent opening closed when the actuator is inactive and for sliding movement to release the lid and open the vent opening upon operation of the actuator.

  • Patent number: 7172591
    Abstract: When a user steps on a footswitch, high-frequency output power is delivered. A control circuit included in a diathermic power supply calculates the impedance ZSn that is offered by a living tissue immediately after delivery of high-frequency output power is started during the n-th delivery period. The control circuit also calculates the impedance ZEn that is offered thereby immediately before delivery of high-frequency output power is discontinued with elapse of predetermined time. The control circuit then discontinues delivery of high-frequency output power for the predetermined time, and calculates a difference ?Zn between the impedances. When the difference meets a predetermined condition that implies coagulation or when the number of times of delivery reaches a predetermined value, the control circuit discontinues delivery of high-frequency output power.
