| 20100001033 | DRY FIRE WARNING DEVICE FOR HAMMER TACKER - A manual hammer tacker having a warning device involving an electric box having a buzzer or a light emitting diode (LED), and at least one battery with both conducting to each other by the electric wires to generate sound or light effect when only few U-shaped staples left during the working process. A reed switch is installed in the tacker and locates near the end route of the U-shaped staples, and is also conducted to the buzzer or the light emitting diode (LED), the battery and the metallic shell by the electric wires. Furthermore, a reed is formed on the pushing guide of the pusher assembly. At the moment when only few staples left, the reed on the pushing guide will be touched with the switch, so that the circuit will become a circuit loop and the buzzer will buzz or the light emitting diode (LED) will glitter to remind the user to reload the staples. | 01-07-2010 |

| 20100175788 | Cutter Assembly and Electric Pencil Sharpener - A cutter assembly for an electric pencil sharpener has a cutter bracket and a cutter. The cutter bracket has a pencil sharpening hole and an engaging structure. The pencil sharpening hole is defined in the cutter bracket for a pencil being inserted into the pencil sharpening hole. The engaging structure is formed on the cutter bracket to engage a rotating frame in the electric pencil sharpener. The cutter is mounted rotatably on the cutter bracket. Accordingly, the cutter assembly is replaceable for the electric pencil sharpener when the cutter of the cutter assembly is damaged or worn off. | 07-15-2010 |

| 20090103068 | EXPOSURE APPARATUS AND METHOD FOR PHOTOLITHOGRAPHY PROCESS - Provided is an exposure apparatus including a variable focusing device. The variable focusing device may include a transparent membrane that may be deformed in the presence of an electric field. The deformation of the transparent membrane may allow the focus length of a radiation beam to be modified. In an embodiment, the variable focusing device may be modulated such that a radiation beam having a first focus length is provided for a first position on an exposure target and a radiation beam having a second focus length is provided for a second position on the exposure target. A method and computer-readable medium are also provided. | 04-23-2009 |
| 20110164234 | NOVEL PHOTORESIST MATERIALS AND PHOTOLITHOGRAPHY PROCESSES - A material for use in lithography processing includes a polymer that turns soluble to a base solution in response to reaction with acid and a plurality of magnetically amplified generators (MAGs) each having a magnetic element and each decomposing to form acid bonded with the magnetic element in response to radiation energy. | 07-07-2011 |
