Title: Improved apparatus for automatically charging electric storage batteries
IPC: H02J7/00
Filed: 1926-01-06
Abstract: 268,064. Wilde, L. A. Jan. 6, 1926. Charging and discharging batteries. - Automatic charging of accumulators is effected through a switch in the charging circuit controlled by an electromagnet through a relay, a catch maintaining the armature of the magnet in raised position and switch in open position when the relay is energized and releasing the armature and closing switch when relay is de-energized. the relay co-operating with the local working circuit which has a hand switch. An electromagnetic cut-out in the battery circuit disconnects the battery when charged to a predetermined voltage. A wireless circuit 1.2 with hand switch A closed obtains current from a battery C, the circuit including the relay B whereby the armature I is held down to contact with the terminal 8. Simultaneously the shunt circuit for the magnet F holds up the armature E carrying the bar 16 for the mercury contacts g of the charging circircuit and the contacts are thus broken. The bar 16 has a retaining catch which is adapted to be moved out of engagement when the link H is moved by the armature E. When the switch A is opened the magnet B is de-energized, the armature I is forced up by the spring 17, trips the lever H and catch J so that the contacts G fall into position to couple the accumulator to the charging circuit. During charging the current also passes through the magnet coil K and at a predetermined voltage, the armature 6 is attracted and contacts with the terminal 25 thereby closing the circuit of the magnets F and causing the contacts G to be lifted to break the charging circuit. For charging from alternating current mains, a transformer having a rectifier in its secondary circuit is coupled to the mains and a mercury switch controls the primary circuit and also the connection of the battery with the secondary circuit.

Title: Metal insulator-semiconductor field effect transistor devices
IPC: H01L21/00
Filed: 1972-01-06
Abstract: 1308888 Semi-conductors ITT INDUSTRIES Inc 6 Jan 1972 [11 Jan 1971] 591/72 Heading H1K A MIS-IC-FET is fabricated on a N-type Si substrate 1 or 111 crystal orientation by depositing layers 2, 3, 4 of SiO 2  thermally grown in steam, Si 3 N 4  glow discharge deposited, and SiO 2  deposited thermally from silane and oxygen; a well being etched over photoresist using buffered dilute HF through layer 4, which acts as mask for etching through layer 3 with hot concentrated H 3 PO 4 ; after which the layers 3, 4 act as mask for etching through layer 2 using HF drawn to the surface of the substrate (Fig. 1e). A layer 9 of SiO 2  is thermally formed in dry oxygen on the exposed substrate (Fig. 1f, not shown) and a layer 10 of polycrystalline Si is deposited thermally from silane, nitrogen, and hydrogen over layers 4, 9 (Fig. 1j, not shown) and the polycrystalline layer may be thermally doped with B 0 ; the doping step being omitted for P channel FET's. A further layer 11 of SiO 2  is thermally formed in dry oxygen (Fig. 1h, not shown) and a photoresist 12 is centrally positioned in the well on layer 11 (Fig. 1i) after the exposed layer 11 is etched out with dilute buffered HF and polycrystalline layer 10 with dilute HF + HNO 3 . The remainder of layer 11 is removed, and the exposed portions of layer 9 are similarly etched out to expose portions 1a, 1b of substrate (Fig. 1k, not shown) and these are bombarded with B ions from BCl 3  to produce source and drain regions 13, 14 where PN positions do not underlie the remaining oxide layers 2, 9 (Fig. 1e). Boron also penetrates the polycrystalline Si layer 10 which thus becomes of P conductivity type. The device is thermally annealed in N, and the layer 10 becomes the gate. Source drain, and gate receive ohmic contacts of, e.g. Al. Plural such devices may be formed on one wafer as discrete or integrated circuits; the latter being separated by standard techniques. Alternatively a sapphire substrate may be epitaxially overgrown with Si into which P is diffused to obtain desired conductivity type and sheet resistivity (Fig. 2, not shown) and N channel devices may be formed (Fig. 3, not shown) by ion bombardment with, e.g. P; the polycrystalline Si layer being P doped as mentioned above and superimposed with an Al ion bombardment barrier also serving as gate electrodes. SiO 2  or Si 3 N 4  may alternately be used as ion bombardment barrier.

Filed: 1961-01-06
Abstract: 896,679. Valve pulse generating circuits; pulse modulation circuits. BENDIX CORPORATION. Jan. 6, 1961 [Jan. 27, 1960], No. 692/61. Classes 40(5) and 40(6). A pulse generator of variable frequency comprises two pentodes 62 each with regenerative R-C coupling between screen and suppressor grids and each screen grid is coupled through capacitors 68, diodes 70 and cathode follower tubes 72 with the control grid of the other pentode so that each is fired alternately to charge the suppressor grid negatively and prime the valve for commencement of anode voltage rundown (due to the suppressor grid time constant circuit discharging). After the anode potential has run down cathode current mainly goes to the screen lowering its potential and producing a decrease in control grid potential of the other pentode, causing its screen and coupled suppressor grid to rise temporarily in potential, the suppressor grid then negatively re-charging so that the sawtooth output commences again. Moreover this reciprocal switching action is arranged to precede the switching over of each tube which would in any case arise when its anode potential runs down sufficiently low. The pulse frequency is varied by a variable D.C. signal applied to a high impedance negative feedback input circuit comprising a cathode follower 24 with anode connected to a cathode follower 34 whose cathode is connected through voltage droppers 40 and a potentiometer 42 with the control grid of a valve 48 series connected with the first cathode follower 24 so that its output commences nominally at zero volts and is applied through resistors 58 to the control grids of the pentodes. This determines the slope of the anode voltage rundown and hence pulse frequency. Initial frequency adjustment is made by a potentiometer 86 connected through the diodes 70 with the pentode anodes to limit their rundown starting voltage. The suppressor grid negative charge pulses arising on the pentodes being primed are amplified by valves 92 and through a common cathode follower passed to a regenerative pulse generator 104.
