Abstract: An integrated circuit structure includes a dielectric layer having an upper portion and a lower portion. The dielectric layer is either an inter-layer dielectric (ILD) or an inter-metal dielectric (IMD). A phase change random access memory (PCRAM) cell includes a phase change strip, wherein the phase change strip is on the lower portion and has a top surface lower than a top surface of the dielectric layer, and a bottom surface higher than a bottom surface of the dielectric layer. A first conductive column is electrically connected to the phase change strip. The first conductive column extends from the top surface of the dielectric layer down into the dielectric layer. A second conductive column is in a peripheral region. The second conductive column extends from the top surface of the dielectric layer down into the dielectric layer. The first conductive column and the second conductive column have different heights.

Abstract: A digital manipulator for an inverter and an image display method for the digital manipulator are disclosed. The digital manipulator is connected to and an external computer. The images used by the digital manipulator are edited by editing software in an external computer and are downloaded to LCM of the digital manipulator to display. The digital manipulator has a plurality of function buttons. Corresponding functions of the function buttons are assigned via editing software by a user. As a result, the digital manipulator is more flexible to use, and users are allowed to configure a digital manipulator based on own individual requests and operating habits.

Abstract: A feed drive mechanism and a connecting assembly thereof are described. The connecting assembly includes a main body and an outer sleeve. The main body has a connecting plate and an inner sleeve connected to a side surface of the connecting plate. Two opposite side surfaces of the connecting plate are respectively fixed on a screw nut seat and a lead screw nut of the feed drive mechanism, and a channel surrounds an outer side surface of the inner sleeve. The outer sleeve is sleeved on the outer side surface of the inner sleeve, enables the channel to be formed into a sealed space, and has an inlet and an outlet respectively communicating with the channel, thereby injecting a cooling medium into the channel.

Abstract: An antenna structure for the RFID Tag includes a carrier with an antenna attached to a surface thereof, the antenna being made of conductive material. The antenna is connected to an IC chip electronically. The antenna has a first and second radiating body connected to the IC chip separately. The first and second radiating body is connected to the IC chip and expanded in a coil until a proper length is reached. Thus, the first and second radiating body is spaced properly to construct a coiled antenna.

Abstract: A padlock includes a shackle attached to a lock housing, a lever pivotally disposed in the lock housing and having one end for anchoring legs of the shackle to the lock housing, a carrier slidably received in the lock housing and having an actuating member to selectively disengage the lever from the legs of the shackle and having a number of protrusions. A follower is slidably attached onto the lock housing, and includes an anchoring device to anchor the carrier to the lock housing at selected positions. An operating device includes a number of selected bars slidably attached onto the lock housing, to actuate the protrusions of the carrier, and to move the carrier relative to the lock housing step by step.

Abstract: A loop antenna system. The loop antenna system for a wireless transmission device having a signal end and a ground end, includes a loop antenna having a toroidal helix wire with a first end coupled to the signal end and a second end coupled to the ground end.

Abstract: A parasitic antenna includes a loop antenna and a metallic inductor, which is positioned on a side of the loop antenna and is isolated from the loop antenna. Upon receiving a signal, the loop antenna produces an electric field. The electrical field produced by the loop antenna radiates energy to the metallic conductor, causing the metallic conductor to produce an induced electric current, thereby generating an electrical field radiating outward. Because the direction of the electrical field produced by the metallic conductor is the same as that of the loop antenna, the radiating performance of the loop antenna is enhanced.
