  • Plastic lens, method for manufacturing the same, and imaging device using the same
    Patent number: 9348064
    Abstract: A plastic lens 1 has a lens 2 that effectively functions as a lens at a center and an annular flange 3 that does not act as a lens along a circumference of the lens. A gate 4 serving as a flow channel through which molten plastic is to be poured during molding is formed on a circumference of the flange. The gate is cut and taken away at an angle of inclination so as to include a point of intersection between the gate 4 and the circumferential flange 3, whereby a circumferential flange having a given thickness or more is formed.

  • Ultrasonic atomization circuit and an atomization device using the same
    Patent number: 8222794
    Abstract: An ultrasonic atomization circuit comprises a driving signal generating unit to generate an ultrasonic driving signal, a power unit to amplify and transmit the ultrasonic driving signal to a piezoelectric ceramic lamination, and a buffering unit connecting to the driving signal generating unit and the power unit to reduce the effect by the load of the power unit to the driving signal generating unit. The present invention is directed to provide an atomization device using the above ultrasonic atomization circuit. For the ultrasonic atomization circuit being disposed between the power unit and the driving signal generating unit, the ultrasonic atomization circuit can reduce the effect by the disperse circuits and reactance to the driving signal generating unit, meanwhile need less units and be easy to test.
