Title: Driver circuit for pulse modulation of a semiconductor laser
IPC: H01L33/00
Filed: 1973-11-06
Abstract: 1396085 Lasers NIPPON ELECTRIC CO Ltd 6 Nov 1973 [10 Nov 1972] 51509/73 Heading H1C In a pulse code transmission system in which a semi-conductor laser converts an input train of electrical pulses into a corresponding output train of optical pulses, and in which the presence or absence of a pulse denotes a binary "1" or a binary "0" value, respectively, the intensity reduction of a-binary "1" optical pulse when it follows immediately after a binary "0" optical pulse, due to a lower residual population inversion in the semi-conductor compared with that obtained with successive binary "1" pulses, is overcome by extending the duration or increasing the amplitude of the input binary "1"  electrical pulse. Fig. 1 shows a circuit for increasing the duration of a binary "1" pulse in a train of coded electrical pulses applied to terminal 10, the pulses passing through a delay 3, OR gate 4 and optional amplifier 5 to the semiconductor laser 6. A parallel circuit 12 to the OR gate, comprising an AND gate controlled by a direct connection to terminal 10 and a path including a delay 1 and an inverter 7, is normally inoperative, for successive "0" or "1" pulse inputs, but if a "1" pulse follows a "0" pulse the AND gate is opened at a time such as to lengthen the binary "1" pulse applied to the semiconductor. The delays 1 and 3 have delay times of T and KT, respectively, where T is the pulse repetition period and KT is <T and may be 0À4 T.

Abstract: 1,205,866. 866. Gas turbine plant. GENERAL MOTORS CORP. Oct 31, 1968 [Jan.11, 1968], No. 51690/ 68. Heading FIG. The invention relates to a compressed air supply system comprising a turbine adapted to be connected to the exhaust system of an internal combustion engine, a centrifugal compressor drivingly connected to the turbine, the compressor having an inlet for ambient air and an outlet for compressed air. A flow diverter duct is connected between the compressor outlet and the turbine inlet whereby compressed air may be supplied to the turbine so as to increase the power of the turbine above that obtainable with engine exhaust alone. In the embodiment shown exhaust gases from the I.C. engine 10 may pass through duct 18 to the turbine 22 which is connected by shaft 26 to centrifugal compressor 28, the compressor having an inlet 30 and an air outlet 34 which is connected to a bulk storage chamber 36 for unloading thereof. A duct 40 is provided interconnecting the air outlet duct 34 and the turbine gas inlet duct 18, the duct 40 including a one-way valve 42 and terminating in a nozzle 44 in the inlet duct 18. The I.C. engine 10, which is the power unit of a vehicle, normally discharges direct to atmosphere through outlet 46, the valve 48 being open, but when the storage chamber 36 is to be unloaded the valve 48 is closed so that the exhaust gases pass through duct 18 to drive the turbine 22, the compressor 28 thus being driven and compressed air being supplied to the chamber 36 for unloading thereof. A proportion of air also passes through duct 40 and nozzle 44 into the gas inlet duct 18 so that the turbine 22 develops more power. A relief valve 38 is provided in duct 34.
