[0065]), a control circuit 86, and a signal transmission module [internal torque transducer 94] (see fig.3, para. [0060]), wherein the signal transmission module [internal torque transducer 94] is electrically connected to the control circuit 86 (90) (see para. [0060]), wherein the one end [spindle 78] of the force-multiplier structure [76] (figs.3, 5, 8-9) is assembled onto the detection shaft 40 (rotating section 40 of transducer 34, see figs. 8-9, para’s [0065], [0067], [0068]), Seith teaches (fig.3, para’s [0059], lines 16-23 & [0060] & [0073]) a signal transmission unit [control unit 86 (90)] and a storage unit [memory 88] electrically connected to the signal transmission unit [control unit 86 (90)], Wherein the signal transmission unit [control unit 86 (90)] (of electric tool 70/[70B) (figs.2-3) receives a test data [torque measurement data, torque calibration factor], which is detected (via [torque transducer 34], see fig.2, para’s [0050], [0065]) and transmitted (via communication port 36, communication cable 38, fig.2, para. [0050]-[0051]) by the torque tester [torque calibration processor 18] (of torque calibrating measurement system 10, see figs.1-2), the storage unit [memory 88] stores the test data (see fig.3, para. [0073], fig.11D, step 2800 and see para’s [0078] thru [0083]).) Seith does not mention the signal transmission unit and the storage unit are arranged inside the force- multiplier structure, and the storage unit is electrically connected to the signal transmission unit; CHEN teaches a force multiplier structure [torque multiplier structure 100] (figs.1-3, para’s [0002]-[0005], [0021]), wherein a signal transmission unit [microprocessor 53] (of information transmission circuit 50, see fig.4) arranged inside (via body 10, see fig.1, para. [0030]) the force-multiplier structure 100; and a storage unit [memory 54] (of information transmission circuit 50, see fig.4, para. [0030]) arranged inside the force-multiplier structure 100 and electrically connected to the signal transmission unit [microprocessor 53], wherein the signal transmission unit [microprocessor 53] receives a test data [torque measurement data] (via torque sensor 30, signal pick-up device123, see fig.4, para’s [0030] thru [0033]. It would have been obvious to one of ordinary skilled in the art before the effective filing date of the claim invention to have the signal transmission unit and the storage unit are arranged inside the force- multiplier structure, and the storage unit is electrically connected to the signal transmission unit, wherein the signal transmission unit receives a test data of CHEN in the system of Seith because the effectiveness of the torque multiplier is that the torque sensor is mounted to the torque input shaft to precisely detect the torque value Further, these data of the torque value and angle value are transmitted by an information transmission circuit, in a wired or wireless fashion, to an electronic device, such as a personal computer, a notebook computer, a mobile phone, and a personal digital assistant (PDA), for storage, display and use, whereby a user may directly access the data of torque value and angle value obtained in the torque multiplier through a handy electronic device in order to ensure the operation quality of tightening/loosening bolts and nuts (see CHEN, para. [0009]). However, as to claim 1, (Seith and CHEN in combination) fails to teach the signal transmission unit transmits the test data to the signal transmission module; the signal transmission module transmits the test data to the control circuit; the control circuit drives the force-multiplier structure to rotate based on the test data. As to claim 8, (Seith and CHEN) fails to teach the force-output terminal of the electric tool is assembled with the force-input end of the force-multiplier structure, so that the signal transmission unit is electrically connected to the signal transmission module. Claims 9-10 depend on allowable claim 8. However, formal requirements outstanding (Objection to spec, 35 USC 112 rejection) needs to be corrected and clarified.
