Title: Method of and system for coding a signal
IPC: H03C3/00
Filed: 1976-01-08
Abstract: 1529922 Frequency modulators; frequency demodulators; pulse modulation SOC LANNIONNAISE D'ELECTRONIQUE SLE-CITEREL SA 8 Jan 1976 [28 Feb 1975] 704/76 Headings H3R, H3A and H4L In a pulse or sine wave modulating arrangement, an input analog signal E 1  is cyclically compared in amplitude at 2 with a comparison signal E 2  increasing from an original value until equality with E 1  is reached when it remains constant for a predetermined time and then reverts to its original value and a rectangular signal is generated by switching a bi-stable circuit 17 at the reversions. The rectangular signal is passed through a filter 19 to derive a signal of variable frequency as the analog coded signal. In operation, clock pulses from 6 applied via an AND gate 7 are counted in 12 for the period taken by E 2  to reach equality with E 1  and thereafter the clock pulses are applied via AND gate 8 to a second counter 14 for a predetermined period, at the end of which a memory 27 storing the output of the comparator and counters 12, 14 are reset to start a new cycle. The output of counter 12 is applied to a D/A converter 16 to derive the comparison signal. In the modification of Fig. 3 (not shown), the circuit 17 is connected to the output 30 of memory 27. The coded analog signal may be sent by wires or by radio link (Fig. 4, not shown). The demodulating or decoding arrangement (Figs. 5-9, not shown) comprises a circuit to detect the zero crossings in the received signal and the detected output is applied to a processing arrangement similar to 21 in Fig. 1 and the decoded output is derived by a D/A converter and a filter. Figs. 8, 9 (not shown) relate to arrangements in which the decoded output is obtained in a non-return to zero form.

Abstract: 968,788. Drawing sheet glass. GLAVERBEL. Jan. 7, 1963 [Feb. 21, 1962], No. 751/63. Heading C1M. In the drawing of sheet glass in a drawing chamber with a non-oxidizing atmosphere, starting from a preformed bulb whose thickness decreases in the drawing direction between its upper surface substantially horizontal at the level of the glass bath in a melting tank and its lower surface in contact with a carbon component, the carbon component consists of a horizontal rotary roller. The roller may be rotated at the same peripheral speed as that of the drawing speed or they may differ. Glass sheet 27 is drawn by rollers 9 from a tank of molten glass 2 having a refractory fixed front wall 3 and a vertically movable wall 4 of carbon and over a carbon roller 8. The glass is cooled through ducts 5 in wall 4, the bore of roller 8 and duct 19 in a cooler 18, so that both surfaces are cooled adjacent the glass bulb and the drawing speed can be increased. Further coolers 21, 22 assist setting of the glass to prevent damage by drawing rollers 9. The wall 4 has the sill 7 overlying the roller 8 and the curve 12 follows the curve of the roller. The rear 17 of the wall 4 is also curved in the forward feed direction of the glass. The wall 4 and roller 8 are mounted in a common support 14 and they are adjustable together by a screw 15 to vary the thickness of the bulb. The chamber 24 has an inlet 23 for the injection of nitrogen under pressure. The glass sheet may be drawn horizontally as at 27, obliquely as at 27<SP>1</SP> or downwardly as at 27<SP>11</SP>.

Title: Manufacture of semiconductor wafer
Inventor: YAMADA TOSHIO
IPC: H01L21/322
Filed: 1989-01-05
Abstract: PURPOSE:To reduce particle adhesion even across the rear surface of a wafer and assure gettering effect by etching only the surface of the wafer to remove a surface cut strain layer, and then heat-treating the wafer to produce lattice defects in the wafer from the rear surface cut strain layer. CONSTITUTION:A wafer contained by cutting an ingot has cut strain on the surface and the rear surface thereof with attendant cracks, and hence allow any particle to adhere thereto and heavy metal impurities to be non-uniformly distributed therein. This causes deterioration and variations of characteristics of the device. To eliminate such difficulties, only surface is etched to remove the cut strain layer and hence reduce the adhesion of the particles, and after the cut strain which might produce lattice defects is removed by later heating, the wafer is heat-treated to produce only on the rear surface lattice defects having a gettering effect from the cut strain layer toward the interior. Further, the rear surface is etched in a region where the produced lattice defects remain to further reduce the adhesion of particles. Hereby, there is assured a highly purified wafer to which particles scarcely adhere.

Title: Measuring device for high-voltage part
Inventor: MATSUBARA RIYOUJI
IPC: H02G1/02
Filed: 1992-01-06
Abstract: PURPOSE:To improve the reliability of measurement by controlling the transmission loss of light so as to be small even if an insulating bar bends, and to eliminate the error of the measurement by preventing disturbance light such as sunlight from entering inside the insulating bar. CONSTITUTION:When a hook 2 is brought into contact with a transmission line 1, voltage is converted into a signal suited to phototransmission in a sensor section 3 to drive plural number of light emitting devices 4. Light sent out of the light emitting device 4 propagates through a space transmitting path 10 in an insulating bar 5, and arrives at plural number of light receivers 7. An optical signal is converted into an electric signal in the light receiver 7, and the electric signal is converted into voltage value in a display section 8 to display it there. In the case where the light emitting device 4 and the lighter receiver 7 are plurally arranged in the insulating bar 5, a straight path is secured by any set of them even if the insulating bar 5 bends. On the other hand, the optical signal sent out of the light emitting device 4 is received by the light receiver 7, but when the insulating bar 5 is provided with a light shielding cover 6 on the side of the light receiver 7, the effect of such disturbance light can be eliminated.
