Title: Rotary head type signal recording and reproducing device
Inventor: SATSUBA HARUKI
IPC: G11B5/02
Filed: 1986-07-03
Abstract: PURPOSE:To prevent the deterioration of a frequency characteristic over a wide band by transmitting a signal from a circuit with a low output impedance to a primary side, and from a secondary side to a circuit with a low input impedance in a rotating transformer connecting a rotating cylinder and a main body device. CONSTITUTION:From a circuit with a low impedance through a transistor 9 to form a emitter follower, a recording signal which is not deteriorated at a low area by the impedance component of a transformer, the impedance of a winding and a low output impedance is transmitted to the primary side of a rotating transformer. The signal is transmitted from a secondary side 12 of the transformer through a transistor 16 to form the low output impedance circuit of a base ground to a recoding amplifier 17, and the high area deterioration of a transmitting signal is prevented by the stray capacity of a rotating transformer, leaking inductance, the low input of the primary and secondary sides and the output impedance. Concerning the reproducing signal through a pre-amplifer, the deterioration of the frequency characteristic is also prevented over a wise band.

Filed: 1989-06-19
Abstract: PURPOSE: To generate flying attitude control turques in any directions by supporting two flywheels rotating in opposite directions at the same speed by means of gimbals journalled on a frame, in such a way that the flywheels rotate about parallel axes which lie perpendicular to the axes thereof. CONSTITUTION: Flywheels F1, F2 are supported on gimbals G1, G2 and driven by respective motors M1, M2 to rotate about respective axes Z1, Z2 in opposite directions at the same speed. When a motor MG is actuated, the gimbals G1, G2 are rotated about respective axes X1, X2 via an idle gear TF in opposite directions and at the same speed. The common axis Y of a frame S secured to a spacecraft is formed by the axes Z1, Z2 within a plane perpendicular to the axis X1, X2. Therefore when the gimbals G1, G2 are rotated about the axes X1, X2, the flywheels F1, F2 can also be rotated about the axis Y, whereby torques along the axes X1, X2 can also be obtained and torques in any directions can be produced.

Title: Emphasis circuit
Inventor: MATSUO YASUTOSHI
IPC: H04N5/922
Filed: 1986-07-03
Abstract: PURPOSE:To decrease the amount of emphasis in a stage of pneemphasis at a time when a large amplitude signal is inputted by providing a circuit to multipy an amplitude-limited signal with a second coefficient and to subtract the product from an input video signal. CONSTITUTION:An input signal a1 is supplied to a high-pass filter 9 via a substractor 7 and is used as a signal c1, then amplitude-limited in a limiter 3 to come to be a signal d1. The signal d1 is multiplied by the coefficient K(smaller than one) in a coefficient circuit 8, supplied to the subtractor 7 where it is subtracted from the input signal a1, and goes to a signal b1. The signal d1 is multiplied by X(larger than one) in a coefficient circuit 4, then is added to the input signal a1 in an adder 5 and is used as a signal e1. Which is taken out from an output terminal 6. Since a loop made of the limiter 3 and the coefficient circuit 8 is thus provided, the transfer fuction GL of the limiter 3 gradually approaches zero at a time when a large-amplitude signal is inputted, and its response becomes quicker. As a result, at the said time of large- amplitude signal inputting, the amount of emphasis of the system becomes smaller.

Title: Howling detector
Inventor: FURUKAWA HIROMOTO
IPC: H04R3/02
Filed: 1990-06-14
Abstract: PURPOSE:To realize the howling detector with small hardware scale, low cost and high detection accuracy by calculating a short period average of an absolute value of the output of a differential arithmetic means and comparing it with a predetermined threshold so as to detect howling. CONSTITUTION:A binary means 2 converts an input signal 1 into a zero cross signal, a multiplier means 4 and a 1st delay means 3 obtain a zero cross point and a zero cross period detection means 5 detects the zero cross period. Then a time change in the zero cross period is calculated by a differential means 7 and an average value calculation means 8 calculates its short period mean value. That is, it is utilized that an output of the average value calculation means is very small in the case of a signal of a prescribed period such as howling to allow a howling detection means detects howling. Thus, the detector is realized with less calculation quantity and a simple hardware.

Filed: 1983-08-30
Abstract: PURPOSE:To check the validity of data through a simple circuit by reading out the data on a prescribed address after a power supply is applied again to decide whether the data is valid or not and discriminating the validity of all data based on the result of said decision. CONSTITUTION:When a microprocessor 3 detects the second application of a power supply, the processor 3 reads the data on an address 1000 of an RAM5 to store it to a register A and also reads the data on an address 1001 of the RAM5 to store it to a register B after inversion. Then the processor 3 judges whether the data are equal to each other between registers A and B. If both data are equal to each other, it is decided that all data of RAM5 and 6 are valid. Then a main program is executed. In case no coincidence is obtained between both data, the data of the address 1000 is read and stored to the address 1001 after inversion to execute an initial start action. Therefore, the data of the RAM6 is supplied to a printer 9 when the coincidence is obtained from the results of comparison. While the processor 3 starts again its actuation from the first when the coincidence is not obtained.

Filed: 1991-06-28
Abstract: PURPOSE:To simultaneously read and write concurrently by providing a means making always a write address smaller by a specific value of >=1 than a read address. CONSTITUTION:In the top address of a write data, a column address is shifted forward by the specific value (k) address of >=1 at every resetting. On the other hand, the address set to a write address counter at the time of inputting a resetting signal is transferred to set to a read address register as it is at the time of resetting. Therefore, though the column number of the first address of the data read at every resetting is shifted (k) by (k) address, the number is always larger than the top address of the write data performed simultaneously by (k) address. The timing of operation of this transferring and shifting the column address is controlled by the clock of a system and the operation is performed successively like this.

Title: Stringing of optical fiber compound cable
Inventor: KIMURA YUJI
IPC: H02G1/02
Filed: 1988-06-27
Abstract: PURPOSE:To minimize the elongation of an optical fiber by stringing the compound cable with tensile strength larger than the normal one applied beforehand and by making the elongation of the optical fiber equal to the contracted quantity of a cable section when it is returned to the normal tensile strength. CONSTITUTION:With a traction means, tensile strength is applied to the compound cable. If this tensile strength is increased up to the normal tensile strength 1, the elongation of a cable section (a) will be beta and that of an optical fiber (b) will be  . Under this condition, when the traction is stopped and the other end of the cable is fixed to a steel tower, the elongation   will remain to the optical fiber. Furthermore, if the tractive force is increased and the compound cable is elongated up to the condition of tensile strength 2, elongation gammais given to the cable section while an elongation is given to the optical fiber. If the tensile strength is lowered to the normal one 1 once again, the cable section will by contracted (gamma-beta). If then the tensile strength 2 is determined so as to be equal to the elongation quantity alpha of the optical fiber, the elongation, alpha of the optical fiber can approximately be reduced to zero when the tensile strength is returned to the normal one 1.
