Abstract: 1416456 Remote control of TV receiver; gain control MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 5 Dec 1972 [7 Dec 1971 30 Dec 1971 (3)] 55990/72 Headings H3Q and H3T [Also in Division G4] A remote control system transmitter transmits pulses until a count of the pulses equals a selected number. In a first embodiment (Figs. 1-7, not shown) a digit 0-9 entered on a keyboard is encoded into binary form by a diode matrix and stored in a memory, an astable multivibrator being started to generate clock pulses which are passed by a gate to switch power to an ultrasonic generator and speaker. The clock pulses are also counted and when the count equals the stored binary number, a comparator stops the astable multivibrator and also (for safety) closes the gate. Thus a number of bursts of ultrasonic energy are transmitted equal to the digit entered (except that 0 is sent as 10). At a receiver, the bursts are detected to produce pulses (one per burst) which are counted, the (binary) count being gated out to control channel selection in a TV set after a delay sufficient for all the pulses to have been received. In a modification (Figs. 8-10, not shown), four switches permit the frequency within each ultrasonic burst of the above embodiment to be selected to determine whether the signal is to control channel selection, volume, contrast or brightness (hue and colour are also possible). At the receiver, four frequency discriminators in parallel set respective flip-flops and also drive a counter via an OR gate. The count is decoded by AND gates to be passed by further AND gates selected by the flip-flops. For example, ten of these further AND gates control volume feeding a common volume control output via respective variable resistors. In a further embodiment (Fig. 11-15, not shown) the keyboard has 11 keys, one for on/off (each actuation reversing the existing state of the TV set, i.e. on to off, or off to on), and three each for volume, contrast and brightness control, the three being to command " start increasing ", " start decreasing " and " stop changing (whether increasing or decreasing) ". The receiver counts the pulses representing (by their number) the identity of the key, the count being decoded to perform the control, the counts corresponding to the " stop " keys resetting the counter. The decoder output for on/off switches a control bi-stable, and those for " start increasing" and " start decreasing " control charging and discharging respectively of analogue memories. Hue and colour may also be controlled. In another modification (Figs. 16-17, not shown) of the first embodiment, the diode matrix, besides feeding the memory, also starts an oscillator which, via a gate, drives the counter and switches power to the ultrasonic generator and speaker. The gate is controlled via a monostable multivibrator by the comparator.

Abstract: 1380068 Acoustic holography and imaging HITACHI Ltd 9 Dec 1971 [16 Dec 1970] 57273/71 Heading H4D For reconstructing an image from an acoustic hologram a pattern of electrical strains representing the hologram is generated over the plane of a piezoelectric transducer, the transducer is excited electrically whereby the intensity of the resulting ultrasonic wave emitted from any given spot in the plane represents the elctrical excitation modulated by the magnitude of the strain at that spot, and the pattern of acoustic stress produced in a medium in which the wave propagates is made visible. In the Fig. 4, embodiment, an acoustic hologram in the form of a pattern of polarization is built up in a transducer 14 comprising a piezoelectric plate 141, a photoconductive layer 144, an electrode 142 and a transparent electrode 143. The hologram of object 1 is built up by energizing transducer 2 from an oscillator 3, mixing the output of a scanned receiving transducer 4 with a reference signal from oscillator 3, and applying the detected mixed signal between electrodes 142, 143 while moving a light source 10 over transducer 14 in synchronsim with transducer 4. The image of object 1 is then reconstructed by illuminating transducer 14 with a uniform light source 15 and switching an oscillator 16 across electrodes 142 and 143 to produce the ultrasonic wave, which propagates in a (liquid) medium 18 and forms a three-dimensional acoustic image 19. The image is made visible by providing a suspension of small aluminium flakes in medium 18, or a selected plane of the image may be scanned by an ultrasonic wave detector 21 feeding a cathode ray tube or facsimile receiver 22. The polarization pattern in transducer 14 can be erased by use of a damped oscillation generator 23. In a second embodiment (Figs. 1 and 2, not shown), the acoustic hologram is formed as a photographic transparency in a known manner, by photographing a lamp modulated by and scanned synchronously with receiving transducer 4, and the image is reconstructed by illuminating transducer 14 through the transparency while applying the oscillator 16 output across electrodes 142, 143, the resulting ultrasonic wave being made visible as in Fig. 4. In a third embodiment (Figs. 6A and 6B, not shown), the photoconductive layer is omitted from transducer 14, a polarization pattern is built up in transducer 14 by moving a stylus electrode directly over the piezoelectric plate 141 (which has only one planar electrode), a second planar electrode is laid over plate 141, and the image is then reconstructed as in Fig. 4.

Abstract: 1339588 Hauling apparatus ABEX CORP 21 Dec 1970 [5 Jan 1970] 60680/70 Heading B8B A sheave 11 for tensioning a cable 13 during winding in and paying out from a winch 36, comprises a driven hub 14 over the periphery of which the cable passes, and a pair of resiliently mounted annular plates 15 mounted on opposite sides of the hub for gripping the cable therebetween when external pressure means is selectively applied to the plates to displace them towards each other. The plates 15 are mounted on annular spring plates 16 and have their displacement restricted by nuts and bolts 27, the radially outer peripheries of the plates 15 being tapered on the axial inside and outside to facilitate cable entry and entry into a tapered peripheral groove 35 of a pressure roller 12. The latter, mounted on an axle parallel to the axle of the sheave 11, is moveable radially of the sheave to cause the clamping of the cable by the plates 15, under the control of hydraulic rams 32. The sheave 11 is driven by an hydraulic motor 19, the driving pressure of which is controlled by an adjustable pressure relief valve 47, the rams 32 being operated by the same hydraulic pressure, which can be vented to a reservoir 40 through lines 55, 53 if a solenoid valve 54 is de-energized. The fluid motor drive for the sheave 11 resists the winding in of cable 13 on to the winch 36 and attempts to pull cable from the winch 36 at a greater rate than it is being payed out, whereby the cable between the sheave 11 and winch 36 is always taut. In the embodiment of Fig. 4 (not shown) the resiliently mounted side plates are displaced by a pair of rollers mounted on inclined axles on a bar displaceable radially of the sheave whereby the rollers engage the tapered peripheries of the side plates. In the embodiment of Fig. 5 (not shown) the side plates are displaced by rollers, each mounted on an arm which is pivotable towards the other arm under the action of a floating hydraulic ram connecting the two arms.

Abstract: 1,245,710. Mounting semi-conductor devices; integrated circuit assemblies. HITACHI Ltd. 24 Dec., 1969 [25 Dec., 1968], No. 62897/69. Headings H1K and HIR. A semi-conductor integrated circuit body 10 is mounted in a hermetic housing 16 having a lid 8, side walls 14 through which leads (e.g. 20, 21) extend, and a base made from four stacked insulating ceramic plates 2, 4, 6, 12. The semiconductor body 10 is mounted (by an optional disc 9 of a gold-plated molybdenum) within an aperture of the uppermost (fourth) ceramic plate 12 on a metallized area 13 of the third ceramic plate 6. The electrodes of the body 10 are gold wire bonded to the inner ends of a series of metallic tracks on the uppermost ceramic plate 12. The external leads (e.g. 20, 21) are bonded to the outermost ends of those tracks which extend to the edge of the substrate. Signal leads are connected to the narrow tracks 7 and power supply leads are connected to the broad and thus low resistance tracks 41, 42. Low resistance power distribution to the body utilizes wire bonds between the body and both tracks 41, 42 and short tracks 44-48. Tracks 44 and 48 are connected to one side of the power supply via track 42 and metallization 5 on the top surface of the second ceramic plate 4 by means of metallized through-holes (32, 35, 37) a, b. Tracks 43, 45, 46, 47 are connected to the other side of the power supply, track 41, by a further group of metallized through-holes (31, 33, 34, 36, 38) a, b, c, and metallization 3 on the top surface of the lowermost ceramic plate 2. In the embodiment illustrated a high value capacitor constituted by metallizations 3 and 5 and the intervening second ceramic plate 4 is connected across the power supply, as desired in the off-buffer TTL logic circuit of Fig. 4 (not shown) and the metallization 13 on which the semi-conductor body 10 is mounted is connected to metallization 5. An alternative metallization pattern would instead interconnect metallizations 3 and 13 so that metallization 5 would lie shielded between them. In suggested variants power distribution may be similarly achieved but without the deliberate provision of large capacitance across the power supply (though it may be provided similarly for use in other parts of the mounted integrated circuit), and resistors and further capacitors may be built into the base-plate structure. In the manufacture of the base-plate structure green alumina discs are metallized with desired pattern of molybdenum-manganese, are stacked, and then sintered together.
