Patent number: 10731253Abstract: A gas injector used for semiconductor equipment includes a housing shell, a rotating main shaft and a gas output distribution unit. The rotating main shaft is covered with the housing shell, and includes a plurality of magnetic fluid seals and a plurality of gas transmission tubes. The gas output distribution unit is coupled to a top end of the rotating main shaft, the gas output distribution unit being connected to a ceiling and a susceptor. The gas output distribution unit includes a plurality of boards spaced at intervals between the ceiling and the susceptor, thereby resulting in a plurality of gas output layers for outputting corresponding reaction gases.Type: GrantFiled: January 15, 2018Date of Patent: August 4, 2020Assignee: Hermes-Epitek CorporationInventors: Tsan-Hua Huang, Kian-Poh Wong, Chia-Ying Lin

Publication number: 20140284341Abstract: A thermal container structure includes an upper cover and a container main body. The upper cover and the container main body have corresponding metallic sealing surfaces and threads, respectively. At least the bottom of the upper cover or the whole upper cover is made of a metallic material. All the inside of the container main body is made of a metallic material. When the upper cover is screwed to the container main body, the metallic sealing surfaces contact with each other and are tightened by the screwed force from the upper cover and the container main body, so that the interior space of the thermal container is an all-metal containing space so as to avoid the plastic material from releasing harmful substances and to prevent an accumulation of dirt, residual odors, the growth of bacteria, and so on.Type: ApplicationFiled: February 26, 2014Publication date: September 25, 2014Inventor: KIAN-POH WONG

Patent number: 7891242Abstract: The present invention discloses a sensing device, wherein a hemispherical container containing a liquid dielectric, and the hemispherical container has more than two pairs of electrodes, and the liquid dielectric can trigger the conduction states of the electrodes. A corrosion-resistant material envelops the container. A precision valve is arranged in the container and used to adjust the level of the liquid dielectric and the sensitivity of the sensing device. A buffer necking part is also arranged in the container and used to prevent from non-expected vibration-induced contact between the electrodes and the liquid dielectric. A leakage-proof detection device envelops the hemispherical container, the liquid dielectric, the precision valve, and the buffer necking part and functions to prevent from the leakage of the liquid dielectric. Thus, the present invention can provide an adjustable multi-directional tilt-sensing device for level control.Type: GrantFiled: February 7, 2008Date of Patent: February 22, 2011Assignee: National Chiao Tung UniversityInventors: Pi-Ying Cheng, Kian-Poh Wong

Patent number: 7837201Abstract: The present invention provides an assistant apparatus for surmounting a barrier, which comprises a carrier body, an assistant mechanism, and a sensing/driving apparatus. The assistant mechanism, disposed at a side of the carrier body, having an assistant block disposed at the end thereof, functions to place the assistant block on the ground between the carrier body and the barrier so that the carrier body is capable of surmounting the barrier through the assistance of the assistant block. The sensing/driving apparatus, coupled to the assistant mechanism, functions to drive the assistant mechanism to generate the adjusting movement according to whether the barrier is detected or not. By means of the design of the present invention, the assistant block is adopted to reduce the height surmounted by the carrier each time so that the carrier is capable of surmounting the barrier section by section.Type: GrantFiled: February 13, 2009Date of Patent: November 23, 2010Assignee: National Chiao Tung UniversityInventors: Pi-Ying Cheng, Kian-Poh Wong
