Abstract: PURPOSE:To eliminate the need for the revision of an optical attenuator in response to the length of an optical cable by adopting this system such that the optical transmission intensity of an optical transmitter is automatically corrected so as to input an optical signal with a proper intensity to an optical receiver. CONSTITUTION:A 1st optical transmitter 1 sends an optical signal to a 2nd optical receiver 4 through an optical cable 2 while a 1st optical transmitter 1 changes the optical transmission intensity hourly in the optical transmitter/reception system in which a 1st equipment 300 provided with the 1st optical transmitter 1 and a 1st optical receiver 8 and a 2nd equipment 400 provided with a 2nd optical transmitter 5 and the 2nd optical receiver 4 are connected by optical cables 2, 6. The 2nd optical receiver 4 decides whether or not the light reception intensity of the optical signal to be sent is within a proper range of the optical reception in the 2nd optical receiver 4 and when the optical reception intensity is within the proper range, the 2nd optical transmitter 5 sends it to the 1st optical receiver 8 through the optical cable 6 and the 1st optical receiver 8 activates the holding means of the 1st optical transmitter 1 when it is received that the intensity is within the proper range to keep the light transmission intensity of the 1st optical transmitter 1 constant.

Filed: 1982-03-19
Abstract: PURPOSE:To obtain a miniaturized element by providing reflective films to both surfaces of a material which has a magnetooptic effect at right angles to an optical axis and thus constituting a Fabry-Perot optical resonator. CONSTITUTION:The polarization plane modulating element M has YIG22 as a magnetooptic medium grown on a GGG substrate 21 and both surfaces perpendicular to its optical axis are coated with the reflective surfaces 18 and 19; and an optomagnetic medium is wound with a coil 23 for applying a high-frequency magnetic field and it is connected to a high-frequency power source 24.

Title: Supervising signal repeating system
Inventor: TAKASO KAZUTO
IPC: H04N7/18
Filed: 1987-02-27
Abstract: PURPOSE:To extremely minimize code distortion by sampling a supervising signal at every prescribed number of retiming clock signals and reproducing it, and identifying the bit length of thus reproduced supervising signal. CONSTITUTION:By a retiming generator 10, a supervising signal Z having a bit length of 52mus equal to that of an original supervising signal X is generated, and this signal Z is transmitted to a multiplex transmitter 14. Also, the generator 10 samples a supervising signal C at a time when the counting of retiming clock signals Y reaches n=150; the level at this point of time is outputted from the said point of time to a point of time when n=250 to reproduce supervising signal Z. Thereafter, a supervising signal Z is generated at every time at n=50+100m(m=3, 4, ...). In such a way, a supervising signal C is sampled and reproduced at every time when the counting of timing clock signals increases by 100 starting from n=50, therefore, there occurs almost no difference between the respective bit lengths of a reproduced supervising signal Z and an original supervising signal X, hence a code distortion can be extremely reduced.

Title: Sense amplifying circuit
Inventor: KURAFUJI SETSUO
IPC: G11C11/419
Filed: 1980-04-03
Abstract: PURPOSE:To improve detection sensitivity and to obtain an output stable to fluctuations of the power source, by connecting a couple of transistors (TR), controlled on the basis of levels of a couple of data bus lines, in parallel between the common connection point of a couple of inverters and the reference potential point. CONSTITUTION:When TRs Q13 and Q14 are controlled via bus lines DB' and - DB', TRs Q13 and Q14 increase in conductivity according to the rise of power source VDD and a rise in potential at common connection point N1 of a couple of inverters 11 and 12 is stopped. Therefore, outputs SD and -SD are both stabilized by being stopped from varying in phase. Although the level of common connection point N1 is determined by ratio gm of TRs Q11-Q14, its value never depens upon the magnitude of the differential component between bus lines DB' and -DB'. As the current TR Q13 or Q14 increases according to the level of bus line DB owing to the complementary characteristics between levels DB' and -DB', the other decreases and the total of the both is fixed. Then, the parallel circuit of TRs Q13 and Q14, when the side of earth point VSS is viewed from point N1, is considered to be a constant current source and the detection sensitivity is improved more than a sense amplifier having point N1 connected direct to VSS.
