Title: Derivation circuit device of at least one quality signal depending on quality of received signal
Inventor: YURUGEN KETSUSAA
IPC: H04H20/88
Filed: 1994-03-15
Abstract: PURPOSE: To make it possible to derive a signal depending upon the quality of a received signal by deriving a sub-signal depending upon electric field strength and another sub-signal from a demodulated received signal and combining both sub-signals to form a quality signal. CONSTITUTION: An output signal AM1 from an amplitude demodulator is filtered by a comb filter 2 and averaged by different time constants in respective low- pass filters(LPFs) 6, 7 through a sampling frequency demultiplier 3. A change- over switch 8 transmits either one of output signals from the LPFs 6, 7 as a signal AMC and an weighting unit 9 executes weighting to generate generated noise attenuation.  Another sub-signal generated by a high-pass filter detector 10, a symmetricity detector 11 and a logical network 12 is transmitted through a pulse width discriminator 13 and used as trigger signals for asymmetrical integrators 20, 21 and outputs from the integrators 20, 21 are supplied to a multiplier 23 together with an electric field intensity signal WF2 weighted by an weighting unit 22 and a masking signal for a fault in a low frequency signal is formed by reducing the degree of stereochannel separation.

Title: Optimized winding driving device
Inventor: MAHR PETER
IPC: G11B15/48
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To stop a winding motor at a target position through a prescribed course with a prescribed braking time, by performing open loop control and closed lop control even when the winding motor is in such a state that the motor is braked by means of a servo device. SOLUTION: Two servo circuits respectively use DC motors as winding motors 1 for the control of the motors 1 and for supplying exciting currents to the motors 1. Each servo circuit is provided with a sensor 3 for detecting the revolving motion of each motor 1, and the outputs of the sensors 3 are supplied to a servo processor 5 through a signal amplifier 4. Then the step type open loop control and closed loop control which are performed on each winding motor 1 while both servo circuits are in braking courses, are performed on the basis of, for example, the order of the reference value corresponding to the values of the numbers of revolutions of the motors 1 and stored in a memory 9. When the rotating speed of each motor 1 becomes coincident with the reference value, shifting to the next reference value pair is immediately made.  Consequently, the looping of recording carriers can be avoided.

Title: Improving method for watt loss of thin strip of amorphous magnetic alloy
Inventor: SATOU SHIYUN
IPC: H01F1/16
Filed: 1981-03-28
Abstract: PURPOSE:To reduce watt loss and to utilize a thin strip of an amorphous magnetic alloy for iron cores of power transformers, etc. by introducing linear heat- affected zones into said strip and annealing the same thereby segmenting the heat-affected zones finely. CONSTITUTION:Heat is applied intermittently to a direction of a thin strip of an amorphous magnetic alloy having an angle to its longitudinal direction by using an electron beam or the like in the width direction of the strip. With the heated- affected zones on an outer side, the thin strip of the alloy is wound to form rolled iron cores, after which the iron cores are subjected to strain relief annealing in a magnetic field. By this annealing, the 180 deg. magnetic domains of the heat-affected zones are finely segmented and the watt loss is improved. By this method, the thin strip of the amorphous magnetic alloy of less watt loss is used for the rolled iron cores of power transformers.
