Abstract: When an output shaft is positioned in a first angular position or a second angular position, the output shaft is allowed to rotate from one angular position to the other angular position without rotating a worm wheel. When the worm wheel is rotated to rotate the output shaft from one angular position to the other angular position, the rotation of the worm wheel is transmitted to the output shaft. When the output shaft is placed in the other angular position, driving-force transmission to the output shaft is released, and at the same time, rotation of the worm wheel is stopped.

The process is characterized by calcining the raw materials together with one or more substances, which are selected from the group consisting of hydrogen, water and water vapor, and conductive carbon and/or a substance, which can form conductive carbon by pyrolysis, added thereto. As crystals of the secondary battery cathode material obtained by this process have been controlled fine sizes, the secondary battery cathode material promotes movements of ions of an alkali metal led by lithium between the interiors of grains of the cathode material and an electrolyte to suppress polarization in an electrode reaction, and further, increases an area of contact between the positive material and a conductivity-imparting material to provide improved conductivity so that improvements are assured in voltage efficiency and specific battery capacity.

Abstract: The force from a drive rod driven by an electric motor is transmitted via a link arm pivotally linked to the drive rod and a back door. When the back door is operated in an open direction, the link arm is supported by an open-side support slider and the acting direction of the force applied to the link arm by the drive rod is shifted to the opening direction of the back door. When the back door is operated in a closing direction, the link arm is supported by a closed-side support slider and a closed-side support roller and the acting direction of the force applied to the link arm by the drive rod is shifted to the closing-direction of the back door. The open-side and closed-side support sliders are pressed against the link arm by leaf spring members so that the link arm is prevented from oscillating between the sliders.
