Title: Fm demodulator for magnetic recording/reproducing device
Inventor: TSUJI MASAKI
IPC: H04N5/93
Filed: 1987-01-05
Abstract: PURPOSE:To compensate FM reproduction frequency characteristics against the head characteristic difference caused by the difference of outputs between high and low bands by providing a means which sets a fixed peaking value via each head and changes the mixing ratio between the signals of the route set at the HPF side and those of the route set at the LPF side. CONSTITUTION:The reproduction signal received from a video head 1 is supplied to an equalizer circuit 3 via a preamplifier 2. The circuit 3 has the peaking value set at a fixed level regardless of the characteristic difference among heads and compensates the frequency characteristics of a transmission system. The output of the circuit 3 is led to a branch point P via an AGC amplifier 4. In other words, the level of the signal received from the route set at the LPF side is lowered less than that of the signal received from the route set at the HPF side. As a result, the low band difference is reduced on the route of the LPF by an amount equal to the low band difference allowed by an equalizer means. Thus the reproduction outputs of different frequency characteristics are demodulated by each head and the clear pictures can be reproduced with no variance of picture quality.

IPC: G11C5/12
Filed: 1971-01-05
Abstract: 1306034 Magnetic storage devices MICRO-MINIATURE PARTS CORP 5 Jan 1971 [12 Jan 1970] 503/71 Heading H3B In a method of wiring magnetic ring core planes, magnetic needles to which drive wires are attached are passed through the cores along respective rows and columns. The correct vertical positioning of the wires in each core aperture is achieved by magnetic forces acting on the needles; for example all the row needles may be guided to the lower parts of the apertures, and all the column needles to the upper parts. In Fig. 1, sixteen core planes 54 are placed on a base 10, each plane having a magnetic body with recesses for the cores, Fig. 4 (not shown). The base 10 has eight tracks 18 along which a magnetic shuttle 12 may slide, the shuttle having longitudinal grooves 20, Fig. 3, in which the needles lie. The shuttle body 16 is of aluminium, and has strip magnets 28 embedded in epoxy 30. A sponge rubber clamp may be placed in a recess 14 in the body to hold the needles firmly. The drive wires are wound on a spool 76, and each is attached to a respective needle. Operation.-To thread the rows of four planes, the needles are placed on the shuttle 12 when it is in the position shown in Fig. 1, and are held by the sponge clamp. The shuttle is moved to the right, and the needles enter the first core plane. The clamp is then freed and placed on a bar 61 to hold the needles steady relative to the core plane while the shuttle is moved back to the left. The clamp is then used to hold the needles on the shuttle and the process is repeated until the needles emerge at the other end of the core planes. The remaining rows may then be similarly threaded, followed by the columns. Finally the wires are drawn through the cores using devices 66 clamped to the needle ends. A guide wire 74, Fig. 1, determines whether the needles pass into the upper or lower parts of the apertures of the cores in conjunction with the magnetic forces between the needles and the core plane magnets. A large shuttle may be used to wire all the rows or columns at the same time, Fig. 11 (not shown). More than two wires may be passed through each core.

Title: Improvements in or relating to the manufacture of gramophone records
IPC: B29C43/02
Filed: 1956-01-06
Abstract: 820,277. Moulding gramophone records. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 6, 1956 [Jan. 11, 1955], No. 547/56. Class 87(2). [Also in Groups VIII, XI and XXXVIII] Gramophone records are made from a composite sheet material comprising a core layer of electrically-conducting material and surface layers of resinous material, an electric current being passed through the core layer to heat it and soften the resinous surface layers to enable the latter to take the impression of matrices. Fig. 4 shows one example of such material, consisting of a central layer 27 of paper fibre faced with two aluminium foils 28, 29, and two outermost layers 30, 31 of resinous material, the foils being bare at the edges. Such material is fed in the form of a strip 5, Figs. 1 and 2, to a press comprising stamps 1, 2 to which are secured matrices 3, 4. The strip rests on rollers 8, 9 and the bare edges of the strip are clamped between terminals 10, 12 and 11, 13 by which electric current is passed through the core to heat the strip. The strip being hot, the terminal members 10, 11 are raised to cut off the current and the matrices are moved towards each other to press the strip, a knife 14 cutting a central hole and knives 18, 19 cutting a circular disc from the strip. Such a cut-out disc is shown at 26, Fig. 2. It is not completely cut out, being connected to the strip by portions 22 ... 25. The next part of the strip to be operated upon is shown at 27. Cooling channels 16, 17 in the stamps control the temperature. Another form of the composite material comprises a core layer of a mixture of paper fibres and graphite with polyvinyl chloride-acetate copolymer deposited in situ on the core layer from aqueous suspension. A third form comprises a central non-conductive layer, e.g. of fibre or resin, covered with metal foil on both sides, e. g. as is shown in part in Fig. 5, in which the core layer consists of a non-conducting central calendered fibrous material covered on each side with a tape of metal foil wound in the form of a spiral. In using such a material the centre of a spiral constitutes one contact for the electric current and the end 32 of the spiral is the other contact, the knife 14 acting as a current supply to the centre. Other forms of core layers are made by mixing natural or synthetic resin or cardboard material with carbon or metal powder. The resinous covering layers may be of shellac or vinyl resin or phenolaldehyde or other thermosetting resin, and may be affixed to the core by adhesive or deposited from solution or dispersion.

Abstract: 1,126,821. Clutch control. REGIE NATIONALE DES USINES RENAULT. 6 Jan., 1966 [9 Jan., 1965], No. 724/66. Heading F2L. In order to maintain the current in the coil of an electromagnetic clutch an element having a high temperature coefficient and arranged in close thermal contact with the clutch acts on a low energy level control circuit and modifies the signals applied to the coil so as to prevent reduction of the current as the temperature increases. The arrangement shown is similar to that described in Specification 1,028,964, in which current to the coil 12 of a powder clutch 13 is supplied from a battery 1 through a transformer 7 connected to an ignition coil 4 operated by a circuit breaker 5. The transformer has two secondary windings 9, 10, the latter being connected to the clutch coil 12 through a diode 16 and non-linear amplifier 19. The winding 10 is in series with a synchronous contact switch 14 across which the high temperature coefficient control element 15 is connected. If the clutch input member rotates faster than the output member the switch 14 is opened and element 15 is effective to cause amplifier 19 to supply increased current to coil 12 as the temperature rises.

Jan. 12, 1932, No. 930. Convention date, Jan. 15, 1931. [Class 108 (iii).] A force resisting, measuring, and indicating system, for example, for a weighing-apparatus, dynamometer or tension-measuring apparatus comprises one or more springs of helical or other form composed of ferro-nickel alloy containing in the neighbourhood of 36 per cent of nickel, the alloy having been previously subjected to cold working and time temperature treatment to raise its elastic limit and having an anomalous metallurgical characteristic with respect to change of modulus of elasticity with temperature change whereby one or more springs can be employed to effect the same deflection of the resisting system under a given load at different temperatures. As shown applied to a weighing scale, the weighing springs each comprise two springs 15, 18. The springs 18 are constructed as usual of material having a modulus of elasticity which decreases with increase of temperature, that is, the springs weaken with rise of temperature, whereas the reverse effect is obtained in the springs 15 by constructing them of a suitable alloy of iron and nickel to which may be added carbon, magnesium, cobalt or chromium. The springs 15, 18 are attached to one another and to the frame members 2 and load members 3 by threaded connectors or " calibrators" 16, 17, 19 so that the relative effective lengths of the springs may be adjusted. In a modification, the springs 15, 18 are arranged in parallel instead of in tandem and one spring may be situated within another. Specification 398,817 is referred to.
