Title: Electronic timing device
Inventor: DELANOY DONALD BRIAN
IPC: H03K17/288
Filed: 1958-04-08
Abstract: 867,112. Valve relay circuits. PYE Ltd. April 8, 1959 [April 8, 1958], No. 11054/58. Class 40(6) An electronic timing device comprising a bridge circuit one arm of which comprises a gas discharge tube, and a relay connected across the bridge between the junction of two resistors and the junction of a third resistor and the tube, the arrangement being such that the bridge is unbalanced until the tube strikes, and energizes the relay to operate a contact which causes the tube to strike after a time delay, the bridge then becoming balanced to de-energize the relay and extinguish the tube. As shown, when button B is pressed, relay RL/N is energized, holding in over contact RL1, and opens contact RL2 to allow capacitor Cl to charge from the stabilized potential at the junction of R6 and tube T2 via resistor R4 until the triggering voltage of the tube Tl is reached. The tube will then fire and the voltage at the junction of R3 and Tl will become equal to the burning voltage of the tube. R1 and R2 are so arranged that the voltage appearing at their junction is also equal to the burning voltage of the tube, and the bridge is then balanced and relay RL/N releases. Contacts RL1 open, switching off the supply and contacts RL2 close discharging the capacitor. Further contacts on RL/N may be used to obtain an output from the timer. The reliability of the timer may be improved by connecting a germanium diode D in series with the relay coil. The time constant may be varied by making R4 a variable resistor, or providing several different values of resistor which may be switched into circuit. Alternatively, or additionally several values of switched capacitor may be provided for Cl.

Title: Dynamic focus circuit
IPC: H04N3/26
Filed: 1963-03-20
Abstract: 1,008,998. Cathode-ray tube circuits. RADIO CORPORATION OF AMERICA. March 20, 1963 [April 2, 1962], No. 11151/63. Heading H4T. The beam of a wide angle electrostatically focused cathode-ray tube is maintained in correct focus for all deflection positions by deriving a dynamically varying focus voltage from the junction of the capacitor 28 and linescanning coils 26 (Figs. 1 and 2) or 28<SP>1</SP> and 26<SP>1</SP> (Fig. 3) and after modification, supplying this voltage to the focusing electrode of the tube. The capacitor 28 (28<SP>1</SP>), which is the conventional linearizing capacitor utilized in known linescanning circuits, causes the scanning current in coils 26 to have a general cosine wave shape so that the voltage at point 29, Figs. 1 and 2, has a sine wave shape as shown in Fig. 5 which approximates to the desired parabolic waveform (Fig. 4) required for dynamic focusing except that it is of opposite polarity. The required reversal of polarity is then effected by means of inductance 30 and capacitor 32 (Fig. 1), or by means of the auto-transformer 34 (Fig. 2) and the resulting voltage (Fig. 6, not shown), fed to the focusing electrode of the tube. In the case of the embodiment of Fig. 3, however, the voltage at points 29<SP>1</SP> (Fig. 7), is of the correct polarity and has the desired parabolic shape 40 but because of the high amplitude fly-back pulses 42 which would damage the tube if the voltage was supplied to the focusing electrode without modification the amplitude of the fly-back pulses is reduced by means of an integrating circuit comprising resistor 36 and capacitor 38, resulting in the production of a waveform (Fig. 8, not shown), which may then be supplied to the focusing electrode of the tube.

Filed: 1975-03-19
Abstract: 1504592 Voltage variable capacitor SONY CORP 19 March 1975 [25 March 1975] 11477/75 Heading H1K [Also in Division H3] A resonant circuit comprises an inductor L, Fig. 1 and a capacitive element C formed by a semiconductor junction element which satisfies the equation where C is the capacitance of the element when a voltage V is applied thereto and a junction of the element is reverse biased and C<SP>1</SP> is a constant. Where two such semiconductor elements are connected in series opposition Fig. 14, each element satisfies the equation The semiconductor element provides a varicap which can be used in electronic tuners and provides a resonant circuit with a more linear C/V characteristic (300, Fig. 3, not shown) compared to known varicaps (302) and which reduces tracking error at low voltage and cross modulation distortion. Where only one varicap is used C<SP>1</SP> = C of that varicap. Where other series and/or parallel capacitors are associated with the varicap (Figs. 10-13, not shown) C<SP>1</SP> depends also on these capacitors. Two varicaps can be connected in series opposition for use in an FM tuner Fig. 14 or in parallel (Fig. 15, not shown). The varicap diode includes an N-type semiconductor layer 2 of high impurity concentration formed on one surface of a silicon substrate 1 Fig. 6B by diffusion and a diffusion region 3 formed in the substrate 1 by using a SiO 2  diffusion mask 4. The diffusion region 3 is so formed that its impurity concentration distribution in the direction from the surface 1b to its interior is greater than (Xmo of curve 301, in Fig. 5, not shown). The mask 4 is removed Fig. 6C and an intrinsic semiconductor layer 5 of same or different conductivity type as substrate 1 is formed by an epitaxial method on surface 16. A SiO 2  diffusion mask 7 Fig. 6D is formed with a window at a position opposite the region 3 then a P-type impurity is diffused through the window into layer 5 to form a region 8 to provide a rectifying junction J. A distance d of the predetermined impurity concentration distribution is selected to be in the range 0À1 # 0À5Á. Ohmic electrodes 9, 10, Fig. 6E, are formed in regions 8 and 2. The diffusion region 8 can be omitted and a metal layer coated on the layer 5 opposite the region 3 to form a Schottky barrier varicap diode. The intrinsic semiconductor layer 5 can be alternatively formed by an ion injection method (Figs. 8A-8E, not shown). In a further alternative the layer 5 can be formed as a polycrystalline silicon layer on the surface of the substrate (Figs. 9A-9E, not shown).
