Filed: 1984-11-06
Abstract: PURPOSE:To discriminate the information of a sensor by detecting two pressures of different frequency bands with one laser and to enabling a wide-band pressure detection as well as to divide the frequency with a filter. CONSTITUTION:The outgoing beam B from a laser 1 proceedes through an isolator 10 that prevents the returning beam to the laser 1 and the optical fiber 3a of an optical fiber branch coupler 13, and is branched to the optical fibers 3b and 3c by the optical fiber branch coupler 13, and further is lead to sensors 11 and 12. The laser beam 1/2 of the outgoing beam B that has been lead to the sensor 11, reflects/interferes between the terminal of the fiber 3b and a translucent phono-receiving vibrating film 11a repeatedly. The feedback beam D repeatedly reflected and interfered, propagates again through the optical fiber 3b. The sensor 12 performs likewise. A feedback beam E is synthesized with the feedback beam D by the coupler 13, becomes an output beam F, and is lead to a photo detector 5 via an optical fiber 3d, and is converted to an electrical signal. The electric signal obtained, is divided by a filter 14 to meet the requirement.

Filed: 1992-08-10
Abstract: PURPOSE:To satisfy with the characteristics of reading and writing by placing a reading coil and a writing coil on a common magnetic circuit and making the number of winding turns of the writing coil smaller than that of the reading coil. CONSTITUTION:A reading (R) coil 11 and a writing (W) coil 12 are wound around a reading/writing core 2 and both ends of these coils 11 and 12 are respectively connected to a reading circuit 5 and a writing circuit 6. Each middle tap of both coils 11 and 12 are commonly connected to a common CMN, the number of the winding turns of the reading coil is made, for example, three and that of the writing coil is made, for example, two. Thus, since the number of the winding turns of the reading coil 11 is made larger than that of the writing coil 12, when a digital signal is read from a floppy disk using the reading coil 11, sufficient output voltage is obtd. Also, since the number of the winding turns of the writing coil 12 is made smaller than that of the reading coil 11, the increase of inductance in proportion to the increase of the coil winding turns is evaded and thus, the slow rising of a wiring current is prevented.

Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To obtain the band split amplifier circuit by which low distortion amplification is conducted by maximizing the effect of amplification of signals at each split band. SOLUTION: A low frequency component passing through a low pass filter 17 is subtracted from an input signal to cancel distortion. Furthermore, a high frequency component passing through a high pass filter 23 is subtracted from the input signal to cancel distortion. Moreover, 1st and 2nd preamplifiers 16, 22 are used to match an output impedance of a photo diode 12 and an input impedance of each filter. After low and high frequency signals are individually amplified by the amplifiers 21, 26 and the resulting signals are combined by a coupling circuit, which provides an output. A steep cut-off characteristic is obtained by feeding back negatively an output of each filter, the frequency bands are split almost completely and low distortion amplification is attained. Furthermore, the frequency characteristic within the pass band of each filter is made flat by impedance matching and low distortion is enhanced.
