20100275448 | Pneumatic saw power transmission structure - A pneumatic saw power transmission structure includes a main body, a first transmission module and a second transmission module installed adjacent with each other in a containing groove of the main body. The second transmission module includes a position limit device fixed at the main body for limiting the second transmission module in the containing groove of the main body to constitute the transmission structure of the present invention. | 11-04-2010 |
20100288522 | Pneumatic tool with an improved soundproof device - A pneumatic tool with an improved soundproof device includes a housing whose rear end has a screw hole for supplying a high-pressure gas. The input high-pressure gas drives a pneumatic motor before it leaves the rear end of the housing. A cover covers the rear end of the housing. The cover has a penetrating hole. A guiding element has a guiding section that gradually expands outwards. The guiding element goes through the penetrating hole. An annular ventilation space is formed between the guiding section of the guiding element and the penetrating hole. A gas inlet connector is disposed in the screw hole. The shoulder part of the gas inlet connector stops the guiding element, so that the gas in the ventilation space is guided by the guiding section of the guiding element to escape. | 11-18-2010 |

20120054984 | AIR TOOL HANDLE - An air tool handle includes a first bushing and a second bushing prepared by different molds as two independent objects. The first bushing and the second bushing have a first hollow part and a second hollow part, respectively, that are in communication. The first bushing has several through parts and concave areas. The second bushing has several thin parts complementary to the concave areas and several thick parts connected with the thin parts and filling the through parts outward. The first bushing and the second bushing are combined along the same axial line. The first hollow part and the second hollow part accommodate the first body of an air tool or hand tool. | 03-08-2012 |
20120325510 | IMPACT WRENCH WITH IMPROVED REDIRECTION SWITCH - An impact wrench with an improved redirection switch includes a housing, a motor shell, an on/off bar set, and a redirection switch. The pushing bar of the redirection switch and the redirection valve are connected in tandem along the same horizontal line. The rotational axis of the rotating redirection valve is perpendicular to the penetrating axis of the on/off bar set, instead of the same penetrating axis line. Therefore, the invention achieves the redirection effect without increasing the volume of its handle. | 12-27-2012 |

20120120024 | TOUCH SYSTEM AND OPTICAL TOUCH SYSTEM WITH POWER-SAVING MECHANISM - A touch system and an optical touch system with a power-saving mechanism are presented. The touch system includes a sensing module and a processing module electrically connected to the sensing module; the optical touch system includes an optical sensing module and a processing module electrically connected to the optical sensing module. The processing module modulates a working frequency and/or a working voltage of the processing module according to a touch point count on a touch region, a preset function of the processing module, and/or an imaging count detected by the optical sensing module, so as to decrease a power consumption of the processing module. An electronic device equipped with such system may not only dynamically adjust the working frequency and/or the working voltage of the processing module, but also can determine a working frequency and/or a working voltage satisfying a report rate through an input of the system. | 05-17-2012 |

20140176964 | OPTICAL TOUCH SYSTEM - An optical touch system comprises a first light-emitting unit, a second light-emitting unit, a first image sensor having a first filter, and a second image sensor having a second filter. The first light-emitting unit generates first wavelength band light. The second light-emitting unit generates second wavelength band light. The first light-emitting unit generates first wavelength band light when the first image sensor is capturing an image. The first filter allows first wavelength band light to enter into the first image sensor and blocks second wavelength band light. The second light-emitting unit generates second wavelength band light when the second image sensor is capturing an image. The second filter allows second wavelength band light to enter into the second image sensor and block first wavelength band light. | 06-26-2014 |

20150241507 | Test Circuit And Method - A method is disclosed that includes the operations outlined below. For a plurality of dies on a test fixture, an antenna distance between each of first antennas of one of the dies and every one of first antennas of the other dies is determined. The dies are categorized into die groups, wherein the antenna distance between each of the first antennas of one of the dies in one of the die groups and every one of the first antennas of the other dies in the same one of the die groups is larger than an interference threshold. Test processes are sequentially performed on the die groups. Each of the test processes is performed according to signal transmissions between the first antennas and second antennas of the under-test device each positionally corresponds to one of the first antennas. | 08-27-2015 |

20130295317 | PAPER-MADE COMPOSITE FURNITURE - Paper-made composite furniture comprises at least two connection tubes and at least one spacer that are coupled together. Each connection tube is a hollow tube with an inner side made of stiff paper and an outer side made of smooth paper. The connection tube has at least one latch groove. The spacer is a solid panel made of stiff paper with the outer side coated by smooth paper. The spacer has two sides wedged in the latch grooves of the connection tubes. The stiff paper has characteristics to withstand greater loading and pressure, thus can replace the conventional furniture made of woods, plastics or metal. The invention not only can reduce material, transportation and assembly costs, also can reduce environmental pollution and facilitate carrying and assembly during outing. The smooth paper can be formed with colors, patterns or texts, thus can provide greater visual appeal and ornamental efficacy. | 11-07-2013 |
