Patent number: 7481613Abstract: The water pump comprises: a body, a rotating device, a driving device, an upper cover and a bottom cover. A lower contacting element is mounted below a bearing, and is capable of contacting a bottom end of a shaft. The upper cover has an upper contacting element being capable of contacting a top end of the shaft. When the rotating device rotates, the top end of the shaft touches the upper contacting element in one-point way to avoid the problem of rubbing the blades of the rotating device and the upper cover. Besides, the shaft, the bearing, the upper contacting element and the lower contacting element are made of a waterproof and rustproof material with well wear character to absorb the water or the cooling liquid which can be a lubrication to reduce the wear to extend the life of the above elements.Type: GrantFiled: August 30, 2005Date of Patent: January 27, 2009Assignee: Sunonwealth Electric Machine Industry Co., Ltd.Inventors: Alex Hong, Wei Chen Chen

Patent number: 6755933Abstract: A semiconductor process recording apparatus comprises a buffer circuit and a endpoint recording device. The input terminal of the buffer circuit is connected to an external endpoint apparatus for receiving a first signal output from the endpoint apparatus. The output terminal of the buffer circuit is connected to the endpoint recording device for outputting a second signal representative of the first signal in response to the first signal. When receiving the second signal, the endpoint recording device outputs a feedback signal to the buffer circuit on the basis of the second signal. Because the feedback signal is blocked by the buffer circuit, the external endpoint apparatus is protected from the damage caused by the feedback signal, thereby greatly reducing the production cost and rate of semiconductor manufacturing.Type: GrantFiled: April 19, 2002Date of Patent: June 29, 2004Assignee: Macronix International Co., Ltd.Inventors: Hung-hsiang Wang, Wei-chen Chen, Shuenn-chuan Yu, Pan-kai Liu, Andy Lin, Hsin-chen Liu
