Abstract: A sole includes a bottom layer and a carbon fiber layer. The bottom layer has at least two engaging portions. The carbon fiber layer is penetrated by at least two fitting holes. The at least two engaging portions are engaged with the at least two fitting holes, respectively. The diameter of the at least two fitting holes, which is close to the bottom layer, is less than the diameter of the at least two fitting holes closed to a upside surface of the carbon fiber layer. The at least two engaging portions undergo an injection process so as to be coupled to the at least two fitting holes, respectively, thereby reducing greatly the chance of injury which might otherwise happen to users as a result of separation of the bottom layer and the carbon fiber layer of the sole while the users are running quickly.

Abstract: A flyback converter to control conduction time in AC/DC conversion technology. The flyback converter includes a primary side and a secondary side. The primary side includes a main switch connecting a primary coil to the input of the flyback converter in series. The secondary side includes a secondary coil coupling with the output terminal of the flyback converter. When a switching frequency of the main switch is at a preset first on time in the range between the off frequency and the second switching frequency, the on-time of the main switch continuously changes corresponding to output load changes. When the switching frequency of the main switch is higher than the first switching frequency, the on time of the main switch is constant. The on time is controlled to change linearly, so as to avoid excessive changes in the output voltage ripples, thereby improving circuit efficiency.

Abstract: When a constant on-time flyback converter is in the switch-on stage, the gate voltage of the switch and the input voltage of the flyback converter adopt the primary side of the transformer to control. The gate voltage is controlled by the second control signal generated by the controller. The flyback converter is then turn off to enter the switch off stage. When the flyback converter is in the switch off stage, the secondary side controller on the secondary side of the transformer, based on the output voltage and output current of the secondary side, sends a first control signal to the primary side controller to control the main switch to turn on. Thus, the flyback converter enters the switch-on stage. Therefore, the calculation complexity is reduced, and there is no need to set a blanking time, such that the flyback converter can be used in high switching frequency applications.

Dummy gate finger structures may be provided to ensure desired levels of stress are produced.
