Title: Television receiver cathode ray tube apparatus
IPC: H04N3/26
Filed: 1974-11-07
Abstract: 1478159 Cathode-ray display tube SONY CORP 7 Nov 1974 [12 Nov 1973] 48311/74 Heading H1D [Also in Division H4] In a television receiver the shape of the beam spot is controlled as a function of variations in the level of the video signal (or the luminance signal in the case of a colour television system) in order to increase the sharpness of the displayed image. The invention operates to change the shape of the beam spot as shown in Figs. 1A and 1B such that for increasing and decreasing levels of the video signal the longer dimension of the spot is perpendicular to the beam scanning direction and for constant levels of the signal following an increase in level the longer dimension of the spot is parallel to the beam scanning direction. Fig. 2 shows the described embodiment in which the luminance signal Y0, derived from the video amplifier 17 of a colour television receiver, is supplied to a minimum value detecting circuit 21, (see also Fig. 3A) directly (signal Y0), to the base of transistor 24, via a 0,1 Á sec. delay line 19 (signal Y1), to the base of transistor 25 and via a second 0,1 Á sec. delay line 20 (signal Y2), to the base of transistor 26, the circuit operating to produce at output 34 a modified luminance signal Y3 (Fig. 3B) which is combined with the signal Y1 in an arithmetic circuit 22 to produce a signal (see Fig. 3B) E s  = (Y1-1À3Y3). The latter is then supplied to a differential amplifier 41 producing opposite polarity outputs Eg and E s  which are fed to opposing electrodes 40A, 40B and 40C, 40D respectively (Fig. 4) forming a focusing electrode in the colour display tube 39. In operation during the rising and falling portions of the video signal (Fig. 1A) the signal Eg (Fig. 3B) is positive and the field distribution at the focus electrode is such that a vertically elongated spot is produced having optimum focus in the horizontal direction whereas during the constant high level of the video signal, Eg is negative and the field distribution is such that the spot has optimum focus in the vertical direction and is elongated in the horizontal direction. The improvement in sharpness resulting from this manner of operation is discussed with reference to Figs. 9 to 11 (none shown). Instead of the focus electrode shown, an external electromagnetic system may be employed. The circuit of Fig. 2 is completed by supplying the composite colour signal from amplifier 14 (part of video amplifier 17) via a band-passfilter 35 and chrominance demodulator 36 as colour difference signals R-Y, B-Y to a matrixing circuit 37 for matrixing with the Y1 luminance signal to produce R G and B signals which are supplied to the tube cathodes via respective amplifiers 38R, 38G and 38B.

[Also in Division H2] Welding apparatus, such as percussive welding apparatus, comprises two workpieces 1, 2 originally in contact, which are subsequently separated to form an arc therebetween to melt the end of the member 1, contact between the workpieces then being re-established. With a switch 21 in its normal position capacitors 12, 19 are charged from sources 40, 30 respectively. Welding is initiated by operating the switch 21 into its dotted line positions whereupon controlled rectifiers 10, 18 become conductive to allow the capacitor 19 to discharge through the workpieces 1, 2. Simultaneously capacitor 12 discharges through the primary winding of a transformer 5, firstly by way of capacitor 6, from the lower end of the primary winding to the upper end and capacitor 7 and subsequently by way of inductor 9, from the upper end to the lower end of the primary winding and inductor 8. Thus the coil 4 of a permently magnetized electromagnetic device 3 is firstly energized in one direction to retract the member 1 from member 2 and thereafter energized in the opposite direction to restore the contact between the two members. The electromagnetic device may comprise two elements in parallel which are energized one after the other to cause opposing movements of the workpiece 1. The welding current can be adjusted by means of a variable inductor 14, 31 and in a second embodiment the rectifiers 10, 18 may be paralleled with further rectifiers which are controlled in accordance with the arc current so as to cause increases in the reversed energization of the coil 4 and in the welding current when an arc is formed.

A surge chamber 2 is connected to the lower end of the motor and the space A communicates with the inner space of the motor. The rotary portion of the seal is urged against the stationary portion 5A by a spring 5B. An impeller 9 is mounted on the shaft 6 in the space A. A thrust bearing 17 and a stuffing box 18 are mounted on the pump shaft 15. The motor 1, flexible container 20 of the chamber 2 and the chambers A and B are filled with oil, the diaphragm bearing against a tube surrounding the shaft 6. The oil in the chambers A and B may be of the same or differing viscosities. In the particular embodiment, that in chamber B is of higher viscosity than that in chamber A. In use, the oil is heated and expands and is pressurized by the impeller 9, the oil in chambers A and B lubricating the seal faces and the stuffing box 18 respectively. The diaphragm 4 moves outwardly until the pressures in chambers A and B are substantially equal, any excess pressure in chamber B being relieved through valve 19. Expansion of oil in the motor 1 and in chamber A is compensated by container 20. As the oil loss through box 18 exceeds that through the seal, the diaphragm gradually moves outwardly until it is in the position shown dotted, communication between the top and bottom of chamber B then being maintained by a pipe 8. Well liquid then enters chamber B through a valve 7, the oil moving upward towards the box 18. Leakage of oil from chamber A through the seal causes the diaphragm to gradually return to its initial position and when substantially all the oil in container 20 and chamber A is used, the cycle of operation is complete and the unit is withdrawn from the liquid in the well.
