  • Patent number: 9538269
    Abstract: The object of the present invention is that the surplus vibration involved therewith simultaneously generating a sound wave by the vibration of the vibrating cone of the loudspeaker unit is generated in the loudspeaker system, which has impaired the sound quality of the loudspeaker system. The purpose of the present invention is to provide a technique for improving the sound quality by reducing the this surplus vibration which are the loudspeaker frame vibration and the cabinet vibration like a front baffle vibration. The present invention is characterized in being configured with a viscoelastic material layer upon rear portions such as the frame surface of the loudspeaker unit and inside and outside surfaces of each surface configuring the loudspeaker cabinet, and additionally suppresses vibration by addition of a heavy member or pressurization caused by constraint of a binding member.

  • Patent number: 5390597
    Abstract: A compact, low-height offset press of simple construction is easy to use, needs no after-use maintenance such as cleaning the ink roller and is designed for fully automatic operation. Plate support 1 and blanket support 10 consist of endless belts. Etching unit 60, dampening unit 70 and inking unit 80 are placed along the periphery of the plate support. An unetched plate is supplied from the plate supply unit and etched automatically for printing. When the press is not in use, anti-drying tank 95 moves up, enclosing the roller(s) in liquid, to prevent any ink on the roller surfaces from drying.
