The rotation transmitting device comprises a pulley connected to a shaft so as not to rotate relatively, and a supporter for supporting the pulley rotatably through a bearing. The profiles are defined by personal characteristics including age, gender, clinical history, etc. The higher boiling sulfides are removed as bottoms along with any C6 and heavier materials. The first voltage variable material is in a conductive state when an ESD event occurs, such that the via is electrically connected with the first metal layer to form a discharge path, and the first voltage variable material is in an isolation state when the ESD event is absent, such that the via is electrically isolated from the first metal layer. The apparatus to perform the method includes a heater assembly providing the heat pipe installed therein and having a holder for holding the heat pipe to be positioned, and a sealer unit located above the heat assembly and having a clamping element and a driving mechanism to operate the clamping element.
