Abstract: A home port for a semiconductor manufacturing nozzle head includes a body having a discharge space configured to receive treatment liquid discharged from a plurality of nozzles, discharge flow passages connected to be in communication with the discharge space and penetrating through the body so as to face the plurality of nozzles, and a cleaning liquid distribution system, which is formed to penetrate through the body, and is connected to transfer a cleaning liquid to the discharge flow passages. The cleaning liquid distribution system includes supply flow passages connected to supply the cleaning liquid to the discharge flow passages, and a lead-in passage connected to and which joins the supply flow passages, and connected to receive the cleaning liquid injected from the outside.

Abstract: An auto lock mechanism of a clock spring for a vehicle is provided. The auto lock mechanism comprises a rolling plate provided in an internal space of the clock spring such that the rolling plate is rotated by a flat cable, and an auto lock unit locking a rotor automatically in such a manner that at a neutral position of the clock spring, where a first locking groove of the rolling plate and a second locking groove of a stator, defining the internal space of the clock spring, overlap with each other, wherein the auto lock unit engages with the first and second overlapping locking grooves to lock the rotor.
