Patent GB-1304866-A (GB)
IPC: H01L21/761
Filed: 1970-09-15
Abstract: 1304866 Semi-conductor devices TEXAS INSTRUMENTS Ltd 15 Sept 1970 44014/70 Heading H1K Redistribution of dopant from shallow preformed surface regions of a semi-conductor body to form relatively deep regions is enhanced by bombarding the preformed surface regions with low mass ions from the group comprising protons, α-particles, neon, argon, krypton or xenon while maintaining the body at a temperature below about 1000‹ C., preferably in the range 450-700‹ C. The point defects produced in the body by the bombardment cause the dopant atoms, which may be initially introduced into the shallow region by diffusion or ionimplantation, to be redistributed into a deep region whose depth depends upon the bombarding energy and which extends downwards into the body with negligible lateral spreading. In the Si integrated-circuit transistor shown as buried N+ type P or As doped sub-collector region, a P type B doped isolation wall 23b, 23b<SP>1</SP> and an N + type P or As doped collector contact region 34b are all formed by proton-bombardment-enhanced diffusion in a P type substrate 10 or an N type epitaxial layer thereon. Metal masks, e.g. of Al, Cr or Au, are used to define the areas which are to be bombarded in each of the various dopant-redistribution stages. The integrated circuit may also include diodes and resistors similarly isolated.

Abstract: 1309830 Photographic type - composing UNITED KINGDOM ATOMIC ENERGY AUTHORITY 2 Aug 1971 [19 Aug 1970] 40027/70 Heading B6W [Also in Division H4] In photographic typesetting apparatus different parts of a text to be typeset are displayed on respective cathode-ray tubes 6, 8, 10, 12 (Fig. 1) and imaged on respective areas 6B, 8B, 10B and 12B of a photographic recording medium 14  means being provided for adjusting the position of the display on each tube such that the images on the medium 14 are aligned with each other to make up the text to be typeset. The aligning means includes a reflective grid member 28 defining four windows positioned vertically above the areas 6B, 8B, 10B and 12B together with nine sets of reference slits, 42, 44, 46, 48, 50, 52, 54, 56 and 58, mounted above grid 28, the slits of all sets except the set 50 being positioned outside the vertical projection of the area defined by the edge strips of grid 28, the slits, in the aligning operation, passing light reflected from the grid 28 to respective photo-cells of which only one, 60, associated with slits 58, is shown. The aligning procedure then consists of deflecting the beam of each tube, in turn, so that it is successively positioned at each of the four corners of the associated reflective grid window and at each such position a small adjustment of the beam in the X and then in the Y direction is effected until light strikes the grid at such an angle that the corresponding slits, e.g. 5A and then 5B, allow the reflected light to fall on the associated photo-cell, e.g. cell 60. The output of the latter is then utilized to define the position of the corner in terms of the X and Y scanning parameters and this information is stored in data processing equipment which controls the whole display operation. During the aligning procedure a small area raster scan may be imparted to each tube beam and by monitoring the waveform of the photocell response the astigmatism of the beam spot may be checked. The spot focus may also be checked by providing pin holes near the slits or astigmatism and focus may be checked by employing pin holes instead of slits. The light from the slits or pinholes may be conveyed by fibre optic light guides.

Abstract: 1338554 Frequency to voltage converters; non-linear waveform generators and frequency multipliers ROBERT BOSCH GmbH 29 March 1972 [30 March 1971] 14653/72 Headings H3A and H3T A frequency to voltage converter comprises a monostable multivibrator 110, 111, a switch 120 rendered conductive by the trailing edge of the multivibrator output corresponding to the end of the unstable period for charging a first capacitor 121, a discharge circuit 13 connected to the monostable circuit for discharging the voltage across 121 hyperbolically with time in between the output pulses, and a charge equalizing circuit 15 for charging a second capacitor 170 to the voltage across 121. The discharge circuit 13 includes a diode resistor network 130-139 so that the capacitor 121 discharges in a hyperbolic manner. A differential amplifier 14 compares the voltages across capacitors 121, 170 during the pulse period and renders conductive the transistors 150 or 151 for charging or discharging 170 to the required voltage level. The input signal may be applied via a frequency doubler (Fig. 2, not shown) to the monostable circuit and a protective circuit (Fig. 3, not shown) may be used along with transistors 150, 151 to prevent breakdown. A generator whose output voltage is a hyperbolic function of time comprises a resistor diode network 130-139 connected to the output of a storage capacitor 121. Initially all the diodes 130-133 are conducting so that the effective discharge resistance is low. The voltages at the taps of the voltage dividers differ so that as the diodes become non-conductive one by one, the effective discharge resistance increases to provide a hyperbolic function of voltage. A frequency multiplier (Fig. 2, not shown) consists of two differentiating capacitors connected directly and via an inverting transistor to an input pulse source for producing positive voltage spikes at the leading, trailing edges, respectively, of the input pulse. The negative spikes formed at the same time are shorted to earth by diodes included in the multiplier.

Abstract: The present invention facilitates identification of whether or not an optical disc is a optical disc of which recording capacity is enlarged. A synchronization pattern of ATIP information embedded into guide grooves irradiated with a light spot is made to be different between a high density optical disc and a standard density optical disc of which recording capacity is not enlarged. Specifically, while the synchronization pattern of the standard density optical disc is preferably made into "3T+1T+1T+3T" (where "T" represents a minimum channel bit of a signal obtained by reading a positional information), the synchronization pattern of the high density optical disc is preferably made into "3T+3T+1T+1T" for example. By reading the ATIP information and recognizing the synchronization pattern thereof, it can be easily and quickly identified whether the optical disc has a standard density or a high density. <IMAGE>
