Abstract: A high-potency juicer is disclosed, having a base and a cutting tool turntable, where the base is made up of a body and a middle member joining the body thereon, and the middle member is provided with a cavity. The body is provided with a driving component. The cutting tool turntable is accommodated in the cavity and is rotated by the driving component, where a first filtering net is set up around the circumference of the cutting tool turntable. A first cutting tool is mounted on the ground part of the cutting tool turntable, and a second cutting tool is mounted on top of the first cutting tool, where the first cutting tool and the second cutting tool are joined by a second filtering net at their circumferences. On the one hand it is beneficial not only for the cutting tool turntable to mount more cutting tools but for simultaneous grinding, cutting and squeezing of the foods by a dual set of cutting tools, boosting the efficiency of juice extraction.

Abstract: This invention is to provide a media controller, comprising a touch panel, which is set up to combine with the screen, and each location on the touch panel is equipped with the “touch” feature, where the touch feature is the location at the screen designed to associate with control commands of a multimedia software such that a virtual command of the multimedia software at the screen can be directly controlled by a finger touching at the touch panel; a micro controller unit (MCU), connected with the touch panel and a physical control device, and the MCU receives a command from the touch panel or the physical control device for carrying out operations and for an output, where the control command of the output is transmitted to the PC through a transmitting wire; and the physical control device includes a number of control elements, which empowers the operator to directly control the software virtual control elements on the screen.

Abstract: A digital sound effect processing device includes an analog/digital converter, a digital signal processor, and a digital/analog converter. The analog/digital converter converts analog frequency signals input by a signal input unit into digital signals to be output. The digital signal processor has one input terminal connected with the analog/digital converter and another input terminal connected with a music access unit for collecting digital audio data input by the analog/digital converter and original music data stored in the music access unit and changing the broadcasting sound effects of the original music data according to the digital audio data and then digitally outputting the sound effects. The digital/analog converter converts the digital music output by the digital signal processor into analog music to be broadcast through a loudspeaker.

Abstract: A media controller is disclosed, which is a memory storing device, made up of an operating system and a piece of multimedia software, where the operating system is made merely for the multimedia software and available for the booting. And the multimedia software is an application program running on the operating system and is able to fetch the songs stored in the computer for overdubbing and sound effects processing. The selection of the memory storing device is the first priority to read during the booting. Once the new setting is saved, the computer is then ready to reboot. The memory storing device then takes charge of the execution of the operating system in the memory storing device. A user is then ready to run the multimedia software on the operating system, and further to operate the input device to fetch the songs stored in the computer for overdubbing and sound effects processing, to greatly achieve the stable playing of sound effects by making use of the existing computer equipment.

Abstract: A velocity-detecting device is mainly based on detection of charge, including a circuit board provided thereon with at least two capacitance sensors with potential difference. The two capacitance sensors are provided at different locations for detecting the time difference when a living thing moves and has its charge respectively reaching the critical one preset by the two capacitance sensors for calculating the moving velocity of the living thing, able to detect and calculate the moving velocity of a living thing for carrying out relative reaction to a machine.

Abstract: A sound effect sensing turntable for a digital music broadcaster includes a capacitive charge sensing plate able to independently detect the variation of charge. A signal transmission unit is disposed between the sensing plate and a control plate for transmitting signals and thus, on receiving a signal, the control plate will produce relative sound effect to be output. In operating, when a DJ's fingers slightly touch the turntable, the sensing plate will sense charge variation on the turntable and actuate the control plate to control corresponding sound effect. By detecting the variation of charge on the turntable for controlling sound effect, the mode of touching the turntable of this invention for producing sound effect is like that of conventionally controlling a vinyl record for controlling sound effect, getting rid of conventional defect of producing wrong sound effect due to assembly errors.

Abstract: A device for stabilizing the rotating speed of a record player has a passive element fitted on the same shaft of a rotating, disk, which activates a record to rotate together. The passive element is formed with a surface expanding outward from a center portion fitted with a shaft and having its outer annular portion engraved with annular minute net holes. A sensor facing the positions of the net holes is provided under a printed circuit board for detecting the change of the shifting speed of the net holes. The signal data detected by the sensor is fed to a micro-processor to carry on operation, and after that, the value of the signal data is transmitted back and automatically modulates the voltage supplied to the rotating disk to let the rotating disk and the record rotate steadily.

Abstract: An electric frying pot includes an outer pot body. and an inner pot. The outer pot body is provided with plural support members and a socket on its bottom base having a. micro-switch fixed under to connect the socket. The socket has two notches and an inserting groove on top and a sliding cover inside, a ring electric-heating tube fixed at the bottom of the inner pot, having two thirds embedded therein and two pins protruding at two opposite ends, with an actuating rod longer then the pins fixed between. Thus, when the inner pot is placed in the outer pot body, the actuating rod pushes the sliding cover to move away to let the actuating rod and the pins respectively inserting in the inserting grooves and the notches, synchronously with the bottom of the inner pot pressing the lug of the micro-switch to turn on power.

Abstract: A temperature controller for electric cooking appliances includes a activating button movably provided on an outer surface and a temperature controller fixed inside an electric cooking appliance. The temperature controller has a shaft and a gear fixed on an end of the shaft. The activating button has a connect member extending in the electric cooking appliance, and a base connected to the connect member, which has a rack formed under an upper wall to engage the gear. The rack has a width at least equal to the linear moving distance of the shaft. Then the activating button is moved rightward and leftward, letting the base with the rack move also so that the gear is rotated by the rack, with the shaft rotating to move forward or backward so as to set the wide range of temperature with many stages to be got for heating the electric cooking appliance.

Abstract: An anti-dust cover driving device for a CD player includes a base body, a laser head base unit mounted on the base body and having a laser head. An anti-dust cover is provided above the base body, moved to hide the laser head or not by a driving device consisting of a gear, a shaft, an activating means, and a power device for rotating the gear and the shaft. The anti-dust cover does not hide the laser head when a CD player cover is closed, but is moved to hide the laser head when the CD player cover is opened by means of the driving device. Therefore, the laser head is always hidden and prevented from having dust fall on it whether the CD player is closed or opened. And the anti-dust cover is moved within a short distance, not moving out of the dimensions of the CD player.
