Publication number: 20190228501Abstract: A display method includes: converting, by a fitting unit, a position information into a fitting parameter; constructing, by the fitting unit, a first pattern from the position information; constructing, by the fitting unit, a second pattern from the fitting parameter; calculating, by a calculation unit, an offset information between the first pattern and the second pattern; integrating, by an integration unit, the fitting parameter of the fitting unit and the offset information of the calculation unit into a reference information; and constructing, by the integration unit, a third pattern from the reference information. In a human-machine interface applying the display method, when a user enters an amount of tolerance into the human machine interface, the machining path represented by the third pattern is reproduced on the human machine interface. Thus, the display method can simplify operations of processing the machining path and reduce the load on the memory.Type: ApplicationFiled: April 17, 2018Publication date: July 25, 2019Inventors: Hsin-Chang Chang, Chia-Sheng Chiang, Sheng-Yu Chuang, Chao-Chuang Mai

Publication number: 20190153923Abstract: A two-sectioned back-pressured catalytic converter has a main body, a tail tube, and a honeycomb carrier. The honeycomb carrier is mounted securely in the main body and has a first section relatively proximal to the intake opening and a second section relatively proximal to the exhaust opening. The density of the holes of the first section is higher than that of the second section. Therefore, waste gas has sufficient space for expansion when passing through the first section, and thus the pressure and the temperature are both lowered, solving problems of the back pressure and the backward pushing. The tail tube is securely mounted into the main body to form a baffle. The waste gas will hit the baffle after passing the honeycomb carrier and generate turbulence which can slow down the gas and make the gas fully react with the precious metal coating.Type: ApplicationFiled: November 22, 2017Publication date: May 23, 2019Inventor: HSIN-CHANG CHANG

Patent number: 9810125Abstract: Provided is a catalytic converter, having a first casing, a first honeycomb carrier disposed in the first casing, multiple second casings connected to the first casing, and multiple second honeycomb carriers each respectively disposed in the second casings. The first honeycomb carrier has multiple first metal sheets and a first catalyst layer formed on the first metal sheets. The first metal sheets are disposed in the first casing to form multiple first channels. Each of the second honeycomb carriers has a similar structure with that of the first honeycomb carrier. The materials of the first and the second catalyst layers include platinum, palladium, and rhodium. The exhaust gas is subjected to redox reaction by the first and the second catalyst layers and burned at high temperature, and thus the emission of the harmful components from the diesel engine is reduced.Type: GrantFiled: December 8, 2015Date of Patent: November 7, 2017Assignee: JUMBOMAW TECHNOLOGY CO., LTD.Inventor: Hsin-Chang Chang
