The invention relates to a capacitance type touch control panel input device for user holding to produce capacitance inductor of capacitance type touch control panel. The capacitance type touch control panel comprises: a conductive pen head, made of conductive material for contacting capacitance type touch control panel; a pen body, one end of which connects or deploys conductive pen head; and a connection part, between pen head and pen body, for user holding capacitance inductor producing a capacitance type touch control panel with conductive pen head. The invention comprises conductive pen head, pen body of relative big area for contacting user palm and for user holding, and finger touchable pen body; conductive pen head and connection part can be scarf joint in pairs. The conductive pen head can uses polyester as inside filler of pen head, uses metal material as clad, or uses mixed polyester and metal material as pen head conductive material to increase contact surface with capacitance type touch control panel, thereby resolving problem of relative short moving distance resulting from relative large area of finger for contacting capacitance type touch control panel, and capacitance inducted variation resulting from sweating of hand.

The invention relates to an earphone device which includes a case, a loudspeaker unit and a microphone. The case has a sound out part; the loudspeaker unit is set in the case which includes a vibrating diaphragm and a sound leading hole, the vibrating diaphragm is set between the sound out part and the sound leading hole; the microphone is set in the case and shields the sound leading hole; wherein, the loudspeaker unit receives sound wave come from an ear canal, the microphone receives sound wave through the sound leading hole. A structure design of the earphone device that the sound leading hole is set in the loudspeaker unit makes sound wave generated from the ear canal transmitting to the microphone in the earphone device, so extended setting microphone on the main body as prior art is not needed. The microphone in the earphone device can receive sound wave come from the ear canal, and prevent the microphone from being disturbed by external environment in communication.

The invention discloses a semiconductor seal structure, comprising a substrate which is provided with an upper surface and a plurality of steel pits formed on the upper surface, the upper surface is defined with a wafer arrangement area, the steel pits are arranged on the blank area of a line outside the wafer arrangement area and do not penetrate the substrate; a wafer which is arranged on the upper surface of the substrate and in the wafer arrangement area; a seal body which is formed on the upper surface of the substrate to seal the wafer; thereby being capable of increasing the seal compound area and the wet air invading paths under the situation of not changing the appearance of a product and reaching the effect that wet air resistance is not peeled off from heat resistance.

The invention relates to a chip carrier socket. The chip carrier socket can accommodate a chip, and comprises a pedestal, a floating platform, a plurality of probes and a fixing device. The pedestal can be connected to a chip tester; the floating platform is arranged on the pedestal and comprises a positioning plane which is provided with a plurality of positioning holes; the probes are arranged in the positioning holes; and the fixing device is used for fixing the chip. In the chip carrier socket, the chip can be flatly attached to the positioning plane so that a contact point of the chip isconsistent with the contact condition of the probes; therefore, the testing stability can be increased; and meanwhile, the chip carrier socket can fix the chip, so the chip can avoid being pulled outby a chip pick-and-place head, and the chip carrier socket is quite practical.

The invention relates to a drive circuit and a power converter containing the drive circuit. The power converter comprises a main switch controlled by a driving signal, a main transformer receiving an input power supply in a switching way by the main switch, and a switching circuit which outputs a synchronizing signal and comprises a switch used for determining the receive status of an external connection load power supply; the drive circuit includes a dead pole time controller and an opposite phase generator; wherein, the dead pole time controller is provided with a second switch and a fourth switch, and the fourth switch is controlled by the synchronizing signal to control the conducting state of the second switch; the opposite phase generator is provided with a first switch and a fifthswitch which are controlled by the driving signal, and the fifth switch is controlled by the first and the second switches to output a switching signal that has the opposite phase to the driving signal, and the switching circuit is controlled; furthermore, dead pole time spacing is kept between the synchronizing signal and the switching signal. The invention can actively modify the switching signal, ensures the phenomenon of reverse current not to occur, leads the circuit to be synchronous and improves the drive capability by using the drive circuit.

The invention relates to a material separating device of a test device, which comprises a blockage arm, a first clamping jaw set, a first swing arm set, a second clamping jaw set, a second swing arm set, a first forward pushing block, a second forward pushing block, a third swing arm set, a down pressing seat and a power source, wherein the blockage arm is arranged at the front end of the material separating device and controls the entrance of a first element to be detected; the first clamping jaw set is arranged in back of the blockage arm and used for clamping the first element to be detected; the first swing arm set is arranged in back of the first clamping jaw set and used for controlling and clamping; the second clamping jaw set is arranged at the other side of the front end of the material separating device, positioned in back of the first clamping jaw set and used for clamping a second element to be detected; the second swing arm set is arranged in back of the second clamping jaw set; the first forward pushing block is arranged in back of the first swing arm set and connected with the second forward pushing block, and pushes the first clamping jaw set to move forward; the second forward pushing block controls the motion of the blockage arm; the third swing arm set is arranged in back of the first forward pushing block, and pushes the second and first forward pushing blocks forward; the down pressing seat is arranged above the first, second and third swing arm sets; and the power source is arranged above the down pressing seat and connected with the down pressing seat, and drives the down pressing seat. Because the material separating device has only one power source and the power source drives all elements to separate materials, the material separating speed canbe increased and the volume of a feeding mechanism can be reduced.
