Publication number: 20240100682Abstract: A flexible interface (130) may operably couple a head portion (110, 210) and a shaft (120, 220) of a hand tool (100, 200). The flexible interface may include a retention assembly (160) and a locking assembly (150) including an actuator (152, 250, 250?) defining a locked state and an unlocked state for the hand tool. In the unlocked state, an angle of the head portion may be pivotable relative to a pivot axis (225) substantially perpendicular to a direction of extension of the shaft and, in the locked state, the angle of the head portion is fixed. The actuator may be configured to move in a direction substantially perpendicular to the pivot axis to operate the locking assembly to transition between the locked state and the unlocked state, and configured to move in a direction substantially parallel to the pivot axis to operate the retention assembly to retain hand tool in the unlocked state. A hand tool comprising said flexible interface is also related.Type: ApplicationFiled: January 28, 2021Publication date: March 28, 2024Inventors: Minglin Shi, Cheng Yang, Yi-Hsiang Tseng, Tsung-Hsien Shen

Publication number: 20240082995Abstract: A hand tool (100,200) may include a head portion (110,210) configured to interface with a fastener, a shaft (120,220) and a grip portion at which an operator is enabled to hold the hand tool during operation, and a flexible interface (130,230) configured to operably couple the shaft and the head portion in a locked state and an unlocked state. The flexible interface is also configured to enable the head portion to pivot relative to the shaft about a pivot axis that extends substantially perpendicular to a direction of extension of the shaft. In the unlocked state, an angle of the head portion may be pivotable relative to the pivot axis. In the locked state, the angle of the head portion may be fixed. The flexible interface may include a locking assembly (150) including an actuator (152, 250, 250?) having a locked position defining the locked state and an unlocked position defining the unlocked state.Type: ApplicationFiled: January 28, 2021Publication date: March 14, 2024Inventors: Minglin Shi, Cheng Yang, Yi-Hsiang Tseng, Tsung-Hsien Shen

Patent number: 9610537Abstract: A loop tower CO2 capture system includes a feeding unit, a carbonator, an accumulator, a calciner, a combustion chamber and a gas blower. The feeding unit has a first gas pipe. The carbonator includes multiple first cyclone dust collecting units. The first gas pipe has one end connected to the uppermost first cyclone dust collecting unit. The accumulator is connected to the lowermost first cyclone dust collecting unit, and is located between the carbonator and the calciner. The calciner includes multiple second cyclone dust collecting units. The accumulator is connected to the uppermost second cyclone dust collecting unit. The first gas pipe has the other end connected to the lowermost second cyclone dust collecting unit. The combustion chamber is connected to the lowermost second cyclone dust collecting unit. The gas blower is connected to the first gas pipe of the feeding unit.Type: GrantFiled: May 12, 2014Date of Patent: April 4, 2017Assignees: Industrial Technology Research Institute, Taiwan Cement CorporationInventors: Wei-Cheng Chen, Shoung Ouyang, Chin-Ming Huang, Cheng-Hsien Shen, Heng-Wen Hsu

Patent number: 9143180Abstract: A cell phone charger holder includes a main body, a plug, and an electric cord. The plug has two blades. The main body has a front face provided with a receiving chamber for receiving the plug. The main body has a side provided with an annular groove for winding the electric cord. The main body has a lower portion provided with two positioning hooks for placing a cell phone. The main body has a back face provided with two upright slots corresponding to the blades of the plug. Thus, the plug and the electric cord are positioned and stored completely by the main body. In addition, when the main body is disposed at an inclined state, the cell phone supported by the main body is disposed at an inclined state.Type: GrantFiled: December 27, 2013Date of Patent: September 22, 2015Inventors: Cheng-Hsien Shen, Meng-Ju Shen

Patent number: 8708297Abstract: A support structure for an electronic product includes a base (20), a support block (21), at least one connecting block (22), and an extension block (23). The base has a first guide channel (201) and a second guide channel (202). The support block has a first guide rail (210), a first connecting channel (211) and a side rail (212). The connecting block has a second guide rail (220), a first connecting rail (221) and a second connecting channel (222). The extension block has a third guide rail (230) and a second connecting rail (231). Thus, the base, the support block, the connecting block and the extension block are combined in different manners so that the inclined angle, space and height of the support structure can be adjusted arbitrarily so as to support the electronic product of different specifications and sizes.Type: GrantFiled: September 25, 2011Date of Patent: April 29, 2014Inventor: Cheng-Hsien Shen

Patent number: 7887397Abstract: A knife sharpening bar includes a handle that carries a support bar. A flexible tube is tightly fit over the support bar. A hollow ceramic bar is then fit over the flexible tube with an inside surface of the ceramic bar tightly engaging the flexible tube so that the flexible tube provides a cushioning support between the support bar and the ceramic bar, which protects the ceramic bar from directly bearing any external impact applied to the knife sharpening bar. An internally-threaded cap engages an externally-threaded free end of the support bar and abuts against the ceramic bar to thereby secure the ceramic bar in position on the support bar. Collars or other buffering members can be positioned at opposite ends of the ceramic bar.Type: GrantFiled: January 17, 2008Date of Patent: February 15, 2011Inventor: Cheng-Hsien Shen
