Title: Speaker
Inventor: OKUZAWA KAZUROU
IPC: H04R7/12
Filed: 1979-02-20
Abstract: PURPOSE:To obtain a speaker cone which features the rigidity and the thermal resistance by using the material in which the natural fiber, the inorganic fiber or the chemical fiber is mixed with the main component of the partially-hardened novolak fiber. CONSTITUTION:The novolak fiber which is obtained as the fused yarn with the main component of the novolak resin is mixed with other fiber. Using this fiber mixture, surface 15 of the fiber is hardened via the aldehyde group to form the columnar capsule containing novolak resin 16 inside. This capsule receives the thermal press along with diaphragm material 13 at about 120 deg.C-200 deg.C, and as a result the hardened area on the fiber surface is destroyed. And thus novolak resin 16 oozes out to be sealed to material 13 and then to form reinforcement layer 14. As a result, diaphragm 8 is obtained with the excellent rigidity and high vibration propagation velocity, thus increasing the reproducing range.

IPC: H04N5/44
Filed: 1995-02-08
Abstract: PURPOSE: To automatically switch an aspect ratio by switching the compression or extension ratio of a video signal in accordance with the moving variable of the video signal. CONSTITUTION: An animation deciding circuit 2 decides the moving variable of a picture in one field from a movement detection signal (a) obtained by detecting the moving variable of a video signal in a sampling unit by a movement detecting circuit 1 and inputs a moving picture detection signal (b) to an aspect ratio switching circuit 4. At the time of deciding that the picture is a moving picture, a current mode is switched to a mode reducing the compression or extension ratio of the video signal and an aspect ratio on the center of a screen is made equal. At the time of deciding a still picture, the compression or extension ratio of the video signal is increased and the current mode is switched to a mode in which the aspect ratio on the center of the screen is close to 1 to 1.  Thus the compression or extension ratio of the video signal is switched in accordance with the moving variable of the video signal and the aspect ratio on the center of the screen can be automatically switched.
