Abstract: PROBLEM TO BE SOLVED: To obtain a large absorption characteristic in a broad frequency band and to prevent a malfunction due to an externally incoming electromagnetic wave and an unspecified electromagnetic wave in a wide range generated inside communication equipment and a harmful effect such as interference by laminating two or more kinds of absorption plates whose frequency characteristic trends are different. SOLUTION: Weight is measured in the ratio of 100% carbon powder to 100% weight ratio rubber (EPDM) and mixture is performed by a kneader, and a green sheet with 0.6 to 0.8 mm thickness is subsequently produced while kneaded by a roll mill, further applied to a hot press to undergo curing processing and defined as a sheet of an electromagnetic wave absorber. Next, 230% Fe-Co system alloy powder is measured to the 100% weight ratio rubber, and an absorber plate with 0.5 mm thickness is produced in the same work as in what is mixed with carbon powder. These two kinds of sheet-like absorbers are made two-layer and three-layer laminated plats by using a double coated tape.

Inventor: SASABE KAORU
IPC: H04S5/00
Filed: 1978-03-13
Abstract: PURPOSE:To obtain the stereophonic sound by receiving reversely the monaural signal after converting into the increased false sound image signal. CONSTITUTION:The amplitude modulation is given to the subcarrier signal 2 with the output of signal source 1 simultaneously with application of the output of aural signal source 1 to balanced modulator 3. This amplitude modulated wave is applied to compounding unit 5 along with the output of external signal source 4, and furthermore the pilot signal from divider 6 is compounded at compounded unit 7. Thus, the composite signal is obtained to be transmitted from transmitter antenna 9 after the FM modulation. With reception of the electric wave through the FM stereo receiving device, the subcarrier signal which is the output from source 1 is demodulated with the asymmetric phases. Thus, the aural feeling is increased with no normal position, obtaining the enlarged sound. On the other hand, the output of source 4 is not increased and heard from the center of a pair of speakers.

Filed: 1992-02-17
Abstract: PURPOSE:To reduce the span variation due to the variation of an ambient temperature by making the rates of the variation of hardness of a center diaphragm and a seal diaphragm roughly equal. CONSTITUTION:The materials of a center diaphragm 7 and a seal diaphragm 12, 13 are respectively set such materials that both rates of the variation of hardness per the variation of an ambient temperature are roughly equal. The pressure Hz that acts to the high pressure side and the pressure PL that acts to the low pressure side, individually act the diaphragms 12, 13 and surfaces of silicon diaphragm 8 respectively via sealed liquids 101, 102 so that the diaphragm 8 bends. The bend is detected by a strain gauge 80 and the differential pressure is converted to an electric signal to be output therefrom. At this time the diaphragm is deformed to the low pressure side, thereby the movement of the sealed liquids of 101, 102 due to the differential pressure are absorbed. Therefore, it is possible to reduce span errors when the rates of variation of hardness of the diaphragms of 7, 12, 13 are roughly equal.
