IPC: H02M7/515
Filed: 1982-05-28
Abstract: PURPOSE:To suppress the abnormal rise of a DC voltage at the regenerative operation time by controlling the rate of deceleration so that the DC voltage does not exceed the set upper limit value when a deceleration command signal is inputted. CONSTITUTION:A speed command signal outputted from a speed setter 10 is inputted through a speed slope control circuit 20 to a V/F converter 11 and a subtractor 12. A DC detection voltage is inputted through an insulating amplifier 19 to the circuit 20. The circuit 20 operates to control the rate of deceleration so that the DC voltage does not exceed the set upper limit value when the deceleration command signal is inputted. In this manner, the abnormal rise of the DC voltage at the regenerative operation time can be suppressed without using a regenerative load resistor which increases the loss.

IPC: G02F1/19
Filed: 1987-04-13
Abstract: PURPOSE:To obtain a matrix switch of light by a simple method by using magnetic fluid which partially fills light guides and spaces partly facing a magnetic field generating device for driving the magnetic fluid as a constituting element. CONSTITUTION:The magnetic fluid 4 is prepd. by adsorbing a surfactant to the surface of an ultra-paramagnetic material having about 100Angstrom  diameter and dispersing the same in a soln. For example, Fe2O4, ferrite, Fe, Co, Ni and the alloys thereof are used as the compsn. of the magnetic material. The fluid 4 moves so as to minimize the energy of the space when a magnetic field is impressed to this magnetic fluid 4. The magnetic field for moving the fluid 4 is generated by passing current to conductors 2. The magnetic field is hardly generated in the space between the conductors 2 as the magnetic lines of force generated by the current negate each other when the current of the same direction is passed to the adjacent conductors 2 shown in the figure. The magnetic lines of force generated by the current are added to the space between the two conductors 2 and the strong magnetic field is generated when the current of the reverse direction is passed to the adjacent conductors 2.

Title: Automatic gain control amplifier
Inventor: TANAKA YASUHIRO
IPC: H03G3/30
Filed: 1986-04-18
Abstract: PURPOSE:To easily set the lower limit gain by adding the 3rd differential amplifier circuit having a constant gain to an amplifier whose gain varies from zero to a prescribed value in response to an external automatic gain control signal. CONSTITUTION:The 3rd differential pair amplifier circuit 22 having a prescribed gain is added to a block comprising the 1st differential pair amplifier circuit 20 and the 2nd differential pair amplifier circuit 21 to make an input signal and a load in common.

Title: Magnetic head
Inventor: KOYAMA NAOKI
IPC: G11B5/39
Filed: 1990-04-06
Abstract: PURPOSE:To obtain an excellent offtrack characteristic and shielding characteristic even with the narrow-track MR head by disposing electrode patterns in such a manner as to decrease the magnetic fluxes crossing the electrode patterns. CONSTITUTION:The MR element 1 is inserted between two shielding patterns 2 and 3 and is thus formed. The electrode patterns 4, 5 are formed at both ends of the MR element 1 and are so formed as to be nearly perpendicular to the surface of a medium 7. Since the magnetic fluxes from adjacent tracks do not cross each other, the deterioration in the offtrack by the induced electromotive force is prevented. The electrode patterns 4, 5 are so disposed as to reduce the area of the loop formed of the electrode patterns 4, 5 drawn out of both ends of a magnetosensitive part and the magnetosensitive part, by which the quantity of the magnetic flux crossing this loop is decreased and the induced electromotive force is decreased. The excellent shielding characteristic and offtrack characteristic are obtd. even with the track MR head in this way.

Abstract: 1475747 Platens felting G SIEMPELKAMP & CO 22 Aug 1974 [22 Sept 1973 (2)] 36901/74 Heading D1R [Also in Division B5] Fibre sheets are made by subjecting single or multilayer mats containing fibres and fluid, e.g. wet asbestos cement mats, to compression between platens by (i) applying a pressure pulse to cause felting, and then (ii) applying a consolidation pressure to effect hardening by means of the upper platen, expressed fluid being led away before and/or during compression. The pressure pulse generates a pressure higher than the consolidation pressure and produces a shock-wave which reorients the fibres. If the mat is placed on the lower platen with the interposition of a perforated screen, a needling effect may be simulated. The pressure pulse may be produced by causing the upper platen 3 to fall freely on the mat or by the release of a pressure medium from a vessel to act on said platen; as shown, the upper platen 3 and tup 7 are driven by a piston and cylinder 8 which is actuated by a feeder 16 connected to an accumulator 15 to permit free fall. A return device 9 is provided. The pressure pulse may be so adjusted as to produce a dust layer on the surface of the compressed mat and so minimise tackiness. Moisture may be led away before and during the pulse. The compression pressure is preferably built up immediately after the pulse, if necessary before the collapse thereof. The mat may be held by vacuum on a moving screen 13 which is driven over the lower platen 2. As shown in Fig. 2, this platen is provided with a coarse web 10, a fabric 11 and a fine sieve 12. The screen 13 may be replaced by a filter cloth. The platens 2, 3 may be corrugated for producing shaped sheets.

Abstract: PROBLEM TO BE SOLVED: To provide an attenuator which can increase its maximum attenuation without increasing its insertion loss by controlling the voltage or current applied to every high frequency variable resistance element for controlling the internal resistance of the resistance element and then controlling the attenuation of signals passing through a signal line. SOLUTION: An attenuator 21 includes an attenuation circuit 27 having a 5th PIN diode 39 which is added to a α-shaped circuit 26 having the 1st-4th PIN diodes 22-25. In such a constitution, the control voltage Vc to be applied to the diodes 22-25 and 39 is continuously controlled when the DC bias voltage of a constant level is applied to these diodes from a bias power unit 35. Thus, the internal resistance of each of diodes 22-25 and 39 is continuously controlled. As a result, the high frequency input signals of the microwaves, etc. which are inputted to the input terminal of a signal line 28 are continuously attenuated and outputted from the output terminal of the line 28. In such a way, the flat frequency characteristics of attenuation is enhanced.

IPC: H02J7/00
Filed: 1979-07-19
Abstract: PURPOSE:To constantly hold the load on an electric source circiut and to reduce the capacity of the electric source circuit by controlling charging current depending on the intensity of a sound output from a sound output device. CONSTITUTION:A sound output dfrom a sound output evice 3 is detected with a detector 9, and applied on a controlling circuit 10. The controlling circuit 10 reduces the charging current to a battery 6 when the sound output detected with the detector 9 is high, and increase the charging current when the sound output detected is low through controlling a charging circuit 5. The capacity of an electric source circuit 2 is made sufficient to supply device current required for the maximum sound output of the sound output device 3. Thus the supply of current to the device 3 and charge to the battery are performed simultaneously without the higher capacity of the electric source circuit 2 and the charging operation can be performed effectively.
