Abstract: A video cassette tape recorder capable of driving various functional parks by a single loading motor, thereby obtaining a light, thin, simple and compact construction and reducing the manufacture cost. A construction is provided in which a single loading motor drives a rotation head drum mounted on a rear portion of a base plate, an actuating plate mounted on a bottom surface of the base plate to linearly laterally move between a supply reel and a take-up reel both mounted on a front portion of the base plate, a pinch drive assembly disposed on one side of the take-up reel and adapted to drive the pinch roller, and a front loading housing.

Abstract: A fast winding device for a video cassette tape recorder capable of achieving a fast winding operation at both of tape loading and unloading states by use of a fast winding plate having an extension to which a FF/REW gear is mounted. The device includes an actuating plate mounted on a lower surface of a base plate to move linearly laterally, the actuating plate having a first fast winding actuating groove and a second fast winding actuating groove, a fast winding mode plate disposed between the base plate and the actuating plate to move laterally linearly, a fast return spring for returning the fast winding mode plate to an original position, a FF/REW gear rotatably mounted to an extension of the fast winding mode plate and directly engaged with an idler mechanism, a spring for resiliently supporting a lock lever mounted to the fast winding mode plate, and a ratchet mounted to the fast winding mode plate and adapted to release a locking state of the lock lever.

Abstract: A brake device for a VCR rapidly stopping the rotation of the supply reel and the take-up reel and reducing the number of brake shafts and brake springs. The brake device includes a supply reel soft brake and a supply reel main brake which are rotatably mounted on a common shaft at a side of the supply reel for braking the supply reel. A take-up reel soft brake and a take-up reel main brake are rotatably mounted on a common shaft at a side of the take-up reel for braking the take-up reel. The brake device further includes a pair of brake springs. One of the brake springs is mounted on the common shaft at the side of the supply reel and biases the supply reel brakes in opposed directions in order to make these supply reel brakes come into close contact with the supply reel. The other spring is mounted on the common shaft at the side of the take-up reel and biases the take-up reel brakes in opposed directions in order to make the take-up reel brakes come into close contact with the take-up reel.

Abstract: A method for depositing a passivation layer on a semiconductor structure having a high resistance value polysilicon layer formed thereon while maintaining the high resistance value thereof and comprises sequentially depositing a silicon oxide layer and a silicon nitride layer, on a high resistance value polysilicon layer of a partially completed semiconductor structure to form a passivation layer thereover. The passivation layer including the silicon oxide layer and the silicon nitride layer is annealed with oxygen plasma in a chamber. The annealed passivation layer is then heated in the presence of a conditioning gas in the chamber to thereby maintaining the resistance of the high resistance value polysilicon layer.
