IPC: H01L27/00
Filed: 1968-04-17
Abstract: 1,228,903. Integrated circuit assemblies. HITACHI Ltd. 17 April, 1968 [19 April, 1967], No. 18189/68. Headings H1K and H1R. An integrated circuit consists of a plane array of isolated semi-conductor elements or element groups, the components of the array being interconnected by tracks on the passivation of the two major faces of the array and by pads constituting connections from one side of the array to the other. The array is supported by an insulating substrate. The organization of the array is shown in Fig. 1. The components (not shown in Fig. 1) are arranged in groups 2 each surrounded by interconnecting pads 7 which are used as terminating points for tracks 10 interconnecting various groups 2 and for tracks 8 leading to the terminals 13 of the array. Tracks 11, 9 with similar purposes are provided on that face of the array in contact with the substrate 1. Arrangement within component groups is shown in Figs. 2 and 3. The interconnecting pads 7 surround the group of diodes 3, transistors 4, and resistors 5. In the embodiment shown isolation between elements is provided by air gaps but in varients the edges of such gaps may be passivated and the space filled with polycrystalline semi-conductor, with metal, or with insulator. The pads 7 are provided with diffused regions 18, 21 to lower their resistance. The tracks between the component groups 2 are supported by semi-conductor islands derived with the components and pads from an initial semi-conductor body from which the array is produced. Semi-conductor material is removed as far as possible, however, from regions in which tracks on the two faces cross one another, to reduce coupling between them. Two methods of making the array are described. These differ principally in that in one formation of the gaps which separate or which will separate the elements from one another is an initial step whereas in the other it is the last step. The substrate may be of glass or ceramic. A ceramic substrate may be formed by depositing powder with a low sintering temperature and then sintering. Passivation may be silicon nitride, alumina, or thermally grown or vapour deposited silicon oxide.

Abstract: 1,231,055. Photo-electric determination of position. FEINMESS DRESDEN VEB. July 23, 1968, No. 35028/68. Heading G1A. In photo-electric microscope for determining the position of a mark, graduation &c., relative to the axis of the instrument, light from the mark 3 is split into two partial beams which are each chopped alternately at two different frequencies before detection by a photo-cell. The output of the latter is coupled to two channels each comprising an amplifier 17 or 18 and a low-pass filter 19 or 20, the amplifiers being tuned respectively to the two frequencies. The output of the two-channel system feeds a difference amplifier 21, whose output 22 has an alternating component representative of the deviation of the mark from the optical axis. The chopper 15 used to chop each of the two beams at alternate frequencies is driven by a synchronous motor 16 and comprises a slotted disc, the slots of one half being spaced apart from one another more than on the other half, Fig. 2 (not shown). The outputs of the amplifiers 17, 18 are continuous waveforms of different frequencies having alternate sections representative of the intensity of each partial beam in turn, Fig. 3 (not shown). The low pass filters 19, 20 reproduce the envelopes of these waveforms. The difference of these envelopes will have a zero A. C. component only when the mark is symmetrically located with respect to the two partial beams i.e. on the optical axis. The apparatus is thus used to determine when the optical axis of the instrument, which is gradually moved past a fixed scale 3, passes a desired graduation mark. When the instrument is fixed, a device 23 is moved to oscillate the image of the mark. Device 23 comprises a plane-parallel glass plate which is swung in synchronism with the rotation of the chopper 15 to refract the light beam. The effect is to provide an output from the difference amplifier 21 which has a zero transition representative of the location of the mark. To evaluate this, the signal is differentiated to provide a pulse which causes interruption of counting of reference pulses produced from a feeler 25 running along a scale 24 and coupled with movement of the device 23.

Abstract: 1303617 Feeding sheets POLYGRAPH LEIPZIG KOMBINAT FUR POLYGRAPHISCHE MASCHINEN UND AUSRUSTUNGEN VEB 29 April 1971 12081/71 Heading B8R The separation of sheets from a pile is assisted by air blown against an edge of the upper part of the pile, the pressure of the air or the time during which it is blown or both being controlled in response to the feeder output, e.g. the rotation speed of a printing-machine. A peg 2, Fig. 1, is rotated a small amount in response to the rotation speed, and has secured thereto by a nut 9 a slideway 3, on which is adjustably clamped a slide 4 to which is articulated a rod 6 which moves a throttle slider valve 7 in an air conduit 8. The slide 4 is adjusted according to the sheet properties, and fine adjustment is carried out by adjusting the slider on the peg. In another form, Fig. 5, the rotation speed controls the setting of a potentiometer 21 in a bridge circuit including a potentiometer 27. With the bridge circuit in balanced condition, alteration of the rotation speed produces an imbalance to energize a relay 24 or 25 and drive a motor 31 in the requisite direction to firstly control the potentiometer 27 to restore the balance and secondly to control the throttle valve 7. The regulating curve of rotation speed/air pressure is preset according to the sheet properties by potentiometers 29, 30, while the minimum opening of the valve is preset by resistors 28. If the machine is shut down, a lug 34 energizes a relay 32 to drive the motor to adjust the valve to minimum pressure, and also energizes a relay 35 to open the bridge circuit. At minimum pressure, a limit switch 33 de-energizes the relay 32, and when the machine is started a key 36 de-energizes the relay 35 to close the bridge circuit, wherein the motor 31 opens the valve the requisite amount. Alternatively or in addition, either of the above-described regulating means may actuate a setting member 51, Fig. 7, to adjust a segment 47 of a rotary valve including an inlet 44, a rotor 42 on a shaft 41 of the feeder and an outlet 45 so as to control the time during which the air is blown.

As shown in Figs. 1, 2, 3, 4 the sequence valve S comprises a plunger 33 actuated by the diaphragm 34 and operable to hold a valve  element 29 off a seating 30 to establish communication along the lock line 13 between ports 31 and 32 only when the pressure of the auxiliary line 11 admitted through port 40 is below a predetermined minimum. The port 40 is connected via line 16 with a port 41 of the restrictor valve R and auxiliary line pressure is admitted to valve R through a port 23. The restrictor valve R comprises a perforated disc element 21 coactuable with a seating 22 between ports 23, 24 in the auxiliary line 11, and a piston 25 and stem 26 responsive to the pressure of the lock line 13 admitted through a port 28 and operable to hold the element 21 off its seating 22 while the lock line is pressurized whilst venting of the lock line 13 causes the element 21 to close on to its seating 22; thus full air flow is permitted towards the actuators but only a restricted flow through the disc perforation in the opposite direction. The port 28 of the restrictor valve R is connected with lock line 13 via line 17 to port 39 of sequence valve S. The movement of the hand lever 42 is damped by a plunger 47 extending through a chamber 48 charged with hydraulic fluid, although the damper may be of the moving vane or friction type. As shown, the system is applied to a truck fitted with lock actuators to the rear wheel brakes only but in the embodiment of Fig. 1a (not shown) the system is applied to the tractor of a tractortrailer combination with lock actuators also provided on the front-wheel brakes.
