Title: Sound pressure changing type speaker
Inventor: TAKANO EISUKE
IPC: H04R9/02
Filed: 1986-03-13
Abstract: PURPOSE:To minimize power consumption required for control and to attain a stable control by permitting a permanent magnet to change the magnetic resistance of a circuit with the aid of a magnetic flux control element and changing a magnetic flux density generating in a magnetic gap so as to change sound pressure. CONSTITUTION:In a magnetic circuit 34 a magnetic flux generates in the circuit due to the magnetomotive force of the permanent magnet 20, and appears in the magnetic gap 24. If the magnetic flux control element 26 adjusts a conducting amount to change temperature, magnetic permeability changes to vary the magnetic flux density appearing in the magnetic gap 24. At the time of the magnetic flux control element 26 causes a current adjusted by a variable resistance not shown in figure to flow and conducts so as to attain an energy consumption of about 3W, the part closest to a heater wire 40 on a metallic plate 42 reaches a Curie point, and said plate becomes nonmagnetic, thereby dropping an average magnetic permeability. Then the magnetic resistance of the magnetic circuit 34 changes, and accordingly the density of the magnetic flux generating in the magnetic gap 34 changes, whereby the outputted sound pressure of a speaker 30 can be changed.

Title: Still picture processor
Inventor: KAWAI KIYOYUKI
IPC: H04N11/14
Filed: 1988-03-10
Abstract: PURPOSE:To transmit additional signals regardless of moving or still pictures by delaying the signal of an odd or even line and selecting alternately the signals of the delayed or non-delayed lines. CONSTITUTION:The average of frames of a non-interlaced signal is secured for every two frames and this frame average is allocated to the odd and even lines of an interlaced signal respectively. A still picture processing part 4a delays the signal of the odd or even line by an extent equal to one field and a switching circuit 8a selects alternately the signals of both lines. Thus the interlaced signal is obtained for a still picture. In such a way, no movement component is produced at all between 1st and 2nd fields in each frame of inter lace scanning and therefore, the return component produced in a vertical high range is eliminated owing to the interlace scanning in case the movement compo nent exists between the 1st and 2nd fields. Then the crosstalk of an NTSC signal can be prevented to an additional signal.
