Publication number: 20150060514Abstract: A firing-operation totalizing device for a gas nail gun includes two pressure areas, a pressure feedback unit mounted in a body, and an electric control unit. The pressure areas are constituted by an interior of a combustion chamber and an interior of a cylinder body. The pressure feedback unit outputs a pressure signal in response to each pressure change of at least one of the pressure areas. The electric control unit includes a control circuit that totalizes the number of the firing operations based on the pressure signals received thereby. As such, the totalized number of the firing operations is increased only when a pressure change of the at least one of the pressure areas occurs due to an explosion to totalize accurately the number of effective firing operations.Type: ApplicationFiled: September 3, 2014Publication date: March 5, 2015Inventors: An-Gi Liu, Chang-Sheng Lin

Publication number: 20140377954Abstract: Provided is a method of planarizing a semiconductor device. A dielectric layer is formed over a substrate. A plurality of openings is formed in the dielectric layer. The openings have varying distribution densities. The openings are filled with a metal material. A first chemical-mechanical-polishing (CMP) process is performed to remove portions of the metal material over the dielectric layer. Thereafter, a sacrificial layer is formed over the dielectric layer and the metal material. The sacrificial layer has a planar surface. The sacrificial layer is formed through one of: a spin-on process or a flowable chemical vapor deposition (FCVD) process. A second CMP process is then performed to remove the sacrificial layer and portions of the dielectric layer and the metal material therebelow. The second CMP process uses a slurry configured to have a substantially similar polishing selectivity between the sacrificial layer, the dielectric layer, and the metal material.Type: ApplicationFiled: September 5, 2014Publication date: December 25, 2014Inventors: Hsin-Hsien Lu, Chang-Sheng Lin

Patent number: 8511527Abstract: A dual safety combustion powered tool device includes a push member disposed to be pressed against a targeted surface to bring a lever to turn to be closer to an actuating unit. A trigger body is pulled to move the actuating unit so as to permit an actuating region to abut against the lever and to turn the actuating unit to an orientation where an actuating region is engageable with an ignition switch. Subsequently, a further movement of the trigger body to a final-stage position permits the actuating region to switch on the ignition switch so as to ignite combustion for initiation of a stroke movement of a driver blade. With such construction, undesired firing of the combustion powered tool device can be avoided.Type: GrantFiled: August 9, 2011Date of Patent: August 20, 2013Assignee: Basso Industry Corp.Inventors: Jung-Mao Ho, Chang-Sheng Lin, Sheng-Man Wang
