Publication number: 20140017981Abstract: Among other things, one or more techniques and/or systems are provided for driving a body of a polishing head using an alignment gear. That is, an alignment gear, coupled to a housing of the polishing head, can transfer rotational force from the housing to the body responsive to the alignment gear being mated with a channel associated with the body. For example, the housing can supply pressure to the body, resulting in the body and the housing moving towards one another into a mated state. When the body and the housing are in the mated state, the alignment gear can mate with the channel (e.g., the alignment gear can fit within the channel). In this way, the alignment gear can drive the body by transferring rotational force to the body, resulting in the body rotating a semiconductor wafer against a polishing pad to polish the semiconductor wafer, for example.Type: ApplicationFiled: July 12, 2012Publication date: January 16, 2014Applicant: Taiwan Semiconductor Manufacturing Company LimitedInventors: Pei Tang, Kun-Tai Wu

Patent number: 7669797Abstract: A foldable boarding ramp is operatively connected to a door opening provided in a body and is selectively extendable to the ground. The foldable boarding ramp is stored in a folded state inside a fairing covering a connecting portion between the body and a main wing. Thus, a reduction in the space of a passenger compartment and a cargo compartment due to the storage of the folded boarding ramp is prevented. In addition, an increase in air resistance can be suppressed without providing a dedicated fairing for covering the boarding ramp. Further, an interlocking member connects together a door for opening and closing the door opening and the boarding ramp when the door is opened. The boarding ramp may be automatically deployed to improve convenience.Type: GrantFiled: April 3, 2007Date of Patent: March 2, 2010Assignee: Honda Motor Co., Ltd.Inventors: Wataru Yada, Hiroshi Yamanouchi

Patent number: 6779619Abstract: A parking pawl is implemented on a series type, hybrid electric vehicle by providing a transmission having a moveable locking plate. The locking plate is used to selectively engage and disengage from one of the power transfer gears of the transmission. While the locking plate is linearly moveable between engaged and disengaged position, it is locked against rotation and prevents rotation of the power transfer gear when engaged thereto. An electromagnet is used to pull the locking plate from an engaged position to a retracted, disengaged position. A compression spring biases the plate toward the engaged position with the rotating gear. The locking plate can be held in the retracted position by moveable locking pins to avoid any need to keep the electromagnet energized.Type: GrantFiled: August 12, 2002Date of Patent: August 24, 2004Assignee: International Truck Intellectual Property Company, LLCInventor: James A.
