Abstract: A diode array includes a substrate and a plurality of light emitting diodes disposed on the substrate and arranged in an array. Each of the light emitting diodes includes a stack of functional layers includes a first semiconductor layer, a second semiconductor layer, and a light emitting layer located between the first semiconductor layer and the second semiconductor layer. At least one of the light emitting diodes includes a first current limiting region covering at least a portion of the first semiconductor layer, the light emitting layer or the second semiconductor layer; a first electrode electrically connected to the first semiconductor layer; and a second electrode electrically connected to the second semiconductor layer, wherein the first electrode and the second electrode are disposed at the same side of the first semiconductor layer.

Abstract: An article hanger is formed of a hook, a marking plate extending from the hook, a fixed plate fastened at one to the marking plate and provided with a retaining hole, a flexible portion fastened at one end with other end of the fixed plate, and a movable plate fastened at one end to the other end of the flexible portion and provided at the other end thereof with a retaining projection having a slotted head. The movable plate is joined at the other end thereof with the fixed plate such that the slotted head of the retaining projection of the movable plate is detachably retained in the retaining hole of the fixed plate.

Abstract: A lock for preventing theft of an automotive vehicle consists essentially of a support seat, a carrying member, a tightening device, and a lock rod set. The support seat has a bottom seat and a hollow support rod mounted on the bottom seat. The carrying member has a carrying rod which is provided at the bottom end thereof with a receiving portion, a sleeve fastened with the top end of the carrying rod, an arresting block fastened with the midsegment of the carrying rod, and a locking device fastened at the top end of the carrying rod. The tightening device is disposed in the receiving portion of the support rod for fastening the carrying member with the support rod. The lock rod set is fitted into the sleeve and is composed of a lock rod having a shank which is provided at one end thereof with a toothed portion and a hooked block corresponding in location to the arresting block. The shank is further provided at other end thereof with a fastening member.
