Patent number: 8048227Abstract: A compensation plate used in a film coating device includes a main body defining a plurality of guiding holes, a plurality of moveable blades connected to the main body, and a plurality of connectors. Each of the plurality of moveable blades defines two through holes corresponding to one of the plurality of guiding holes. The plurality of connectors engage in the through holes and the guiding holes, fix each of the plurality of moveable blades to the main body when each of the plurality of connectors is fastened, and slide in each of the plurality of guiding holes with each of the moveable blades when each of the plurality of connectors releases.Type: GrantFiled: April 23, 2008Date of Patent: November 1, 2011Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Chih-Wei Tso, Po-Wen Chan

Patent number: 7813064Abstract: A carrier, a locking member, a color filter unit and an elastic member are provided. The carrier includes a main body, a shaft and a lock-receiving portion. The shaft coaxially protrudes outwardly from the main body. The lock-receiving portion is defined in the shaft. The locking member is lockingly received in the lock-receiving portion. The color filter unit is disposed on the main body. The elastic member is interposed between the locking member and the color filter unit and is compressed therebetween to push the color filter unit against the main body. In this way, the color filter unit is firmly fixed on the main body and the color wheel assembly is assembled.Type: GrantFiled: November 6, 2007Date of Patent: October 12, 2010Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Pi-Tsung Hsu, Chih-Wei Tso

Publication number: 20090034106Abstract: An exemplary color wheel for use in DLP projectors includes a motor, a color filter unit, a locking member, and an elastic member. The motor includes a rotor portion. The rotor portion protrudes a shaft. The shaft defines a receiving portion therein. The color filter unit defines a through hole for extension of the shaft. The locking member is slidably engaged with the receiving portion to fix the color filter unit to the rotor portion. The elastic member is interposed between the color filter unit and the locking member.Type: ApplicationFiled: December 4, 2007Publication date: February 5, 2009Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventors: YU-LUN HO, CHIH-WEI TSO

Publication number: 20080180823Abstract: A color wheel includes a motor, a filter and a dark slide. The motor has an adhering section and the filter is affixed to the motor by the adhering section. The filter has a first surface facing the motor and a second surface opposite to the first surface. The dark slide is affixed to the filter on the second surface. The dark slide matches the location and shape of the adhering section to block light from projecting onto the adhering section. The thermal expansion coefficients of the dark slide and the filter are substantially identical to avoid damage from thermal stress caused by heating and cooling. An assembling tool and an assembling method are also provided in the embodiments.Type: ApplicationFiled: October 29, 2007Publication date: July 31, 2008Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventors: CHIH-WEI TSO, CHIN-MING CHUNG, PI-TSUNG HSU, HSIN-LI LIN

Patent number: 7253977Abstract: A method for fabricating a monolithic color wheel. The method includes (a) preparing a square transparent substrate; (b) forming a plurality of color filters on the square transparent substrate; and (c) cutting the square transparent substrate and the color filters together along a circular path, to form a color filter disk. Through these steps, a color filter disk of color wheel can be produced with better dynamic equilibrium quality, and will run more quietly and smoothly.Type: GrantFiled: March 30, 2006Date of Patent: August 7, 2007Assignee: Premier Image Technology CorporationInventors: Pi-Tsung Hsu, Chih-Wei Tso

Patent number: 7173780Abstract: A color wheel with dovetailed balancing groove, includes a motor, a metal ring and a set of color filter set. At a rotatable portion of the color wheel, such as the peripheral portion between the metal ring and the housing of the motor, or on the peripheral surface of the metal ring, a balancing groove with narrow opening and wider inside is formed thereon. Using the feature of a narrow opening and wider inside, glue is added into the opening and dries to become solid balancing material. The color wheel is less prone to deviate from the metal ring, even though a relative larger centrifugal force is induced and acted thereon while the color is running at higher speed and higher temperature.Type: GrantFiled: March 30, 2006Date of Patent: February 6, 2007Assignee: Premier Image Technology CorporationInventors: Pi-Tsung Hsu, Chih-Wei Tso
