Abstract: An integrated circuit structure includes a sub-fin having at least a first portion that is doped with a first type of dopant, and a second portion that is doped with a second type of dopant. A PN junction is between the first and second portions of the sub-fin. The first type of dopant is one of a p-type or an n-type dopant, and the second type of dopant is the other of the p-type or the n-type dopant. A first contact and a second contact comprise conductive material. In an example, the first contact and the second contact are respectively in contact with the first portion and the second portion of the sub-fin. A diode is formed based on the PN junction between the first and second portions, where the first contact is an anode contact of the diode, and the second contact is a cathode contact of the diode.

Abstract: A game token verification system includes a coin passage defined in a game machine, a perforated game token, a game token sensor installed in the coin passage and adapted for sensing movement of the game token through the coin passage and producing a corresponding identification signal indicative of the pattern of the perforations of the game token, and a comparator installed in the game machine and adapted for receiving the identification signal produced by the game token sensor and comparing the received identification signal to a predetermined reference data and recognizing the authenticity of the game token subject to the comparison result.

Abstract: A foldable razor assembly includes a detachable razor blade embedded at the front end of a handle, a box base with its lateral side pivotally coupled to the rear end of the handle, a cavity defined by the box base and a lid for containing the handle and razor blade, and a box body. Since the handle is pivotally coupled to an end of the box base, the handle can be rotated directly to put the handle and the razor blade into the cavity of the box base, and the lid is turned to cover the cavity when the razor is not in use, so as to reduce the overall storage volume of the razor for an easy storage or carry. The invention can prevent the box body from being separated from the razor or missing, and also can keep the razor from being contaminated by the environment. When it is necessary to use the razor, the lid is opened and the handle is turned to combine with the box body. The invention can be folded or unfolded for easy storage or use.

Abstract: A boxed traveling item including a casing, a cover hinged to one side of the casing and having a transverse sliding groove and a retaining hole at one end of the transverse sliding groove, a traveling item hinged to the casing by a hinge and received in a storage chamber inside the casing, and torsional springs mounted on the hinge between the casing and the traveling item to automatically lift the traveling item from the storage chamber when the cover is opened, the traveling item having a hooked retainer rod at the free end, which is moved along the transverse sliding groove and hooked into the retaining hole when the cover is opened.
