Abstract: The avalanche photodiode as a light absorbing layer 3 on top of which is a first window layer 4 on top of which is a second window layer 5. An upper region 6 of the second window layer 5 is relatively heavily doped with an impurity of a conductivity type different from that of the second window layer 5 to provide a p-n junction for avalanche multiplication in the second window layer 5. Around the p-n junction for avalanche multiplication the second window layer 5 and an upper region of the first window layer4 are relatively heavily doped to provide a p-n junction for a guard ring effect in the first window layer 4. 
     p-n Junction 9, in the first window layer 4, for the guard ring effect is approximately 0.5 micrometers above the heterojunction 11 between the light absorbing layer 3 and the first window layer 4. The p-n junction 10 for avalanche multiplication is approximately 1.5 micrometers above the heterojunction 11. 
     A method of manufacturing such an avalanche photodiode is provided in which only one diffusion step is required for forming the p-n junctions 9 and 10 to different depths.

Abstract: A breathing apparatus includes two parallel flowpaths 4 and 12 through which breathing gas can be supplied independently from a cylinder 1 to a facemask 6. The first flowpath 4 includes a shut-off valve 2, pressure reducer 3 and demand valve 5 and provides the normal route through which the user of the apparatus is supplied. In the event of a failure or malfunction of any component of this normal breathing circuit, however, the first flowpath can be isolated by closing the valve 2 and the user can breathe through the second or bypass flowpath by opening a second shut-off valve 11 which has a combined pressure reducer and leads directly to the mask 6. The two valves 2 and 11, together with a cylinder pressure gauge 14 and a safety burst disc 15, are incorporated in a compact valve assembly 13 secured to the cylinder 1.

Title: Apparatus for dropping a liquefied inert gas into a can
Inventor: YAMADA MORIO
IPC: F17C9/00
Filed: 1982-06-08
Abstract: An apparatus is for dropping a liquified inert gas into a can immediately before rolling of the can, to apply an internal pressure to the can after can sealing. Liquified gas is supplied from a liquified gas main tank (5) to a liquified gas storage tank (1) having a gas pressure lower than that of the main tank. The supply is controlled by a bucket or ball type float valve (15) to maintain a constant liquid level at all time. A given amount of liquified gas is dropped from a dropping nozzle (4) into a can by means of a dropping valve (3) actuated by a sensing signal produced when the presence of a can is sensed. The internal pressure of the storage tank is maintained constant by releasing vaporized gases within the tank through a regulating valve (13). This released gas shields the liquified gas passing through the dropping nozzle to prevent vaporization of the gas and freezing of the nozzle. To prevent additionally the nozzle from being frozen, a portion of the nozzle may be made of a suitable synthetic resin.

Abstract: In D/A-converting apparatus which obtains a converted analog signal at its output terminal (11) by selectively yielding a current or currents from one or more current sources (2 1 -2 k+m ) in accordance with an input digital signal, the current sources are selectively actuated to output the currents and an error in the current of each selected current source is obtained from the output derived at the output terminal in response to the outputting of the current. From the current error of each current source is computed a final error corresponding to each input digital signal and corrected data corresponding to the final error is stored in a corrected data memory (31), which is read out by the input digital signal. The output thus read out is converted into an analog signal, whereby a correct converted output is obtained.

Abstract: A data communications system includes a transmitter (100-108) for transmitting messages, each of which include message characters, a verification portion and a message sequence number. The message sequence number for each message differs from the message preceding it. A receiver (110-122) includes means for verifying the accuracy of the received message and for returning to the transmitter a signal which is either an acknowledgement signal, if the message is inaccurately received, or an error signal, if the message is inaccurately received. To prevent the utilization by the receiver of redundantly received messages, which might occur if the acknowledgement signal is incorrectly received atthe transmitter, the receiver includes means (118) for comparing the message sequence number with the message sequence number of the last accurately received message (116) and for storing (126) the message only if the message sequence numbers are different.

Abstract: A valve (20) determines the effective diamter of an exhaust gas recirculation passage (10). A position sensor (30) provides a signal representing the actual position (b) of the valve, and an actuator (40) positions the valve (20). A target value (a) for the valve is set according to predetermined operating conditions of the engine. The actuator (40) is driven with a drive pulse corresponding to a positional deviation between the target value (a) and the actual position (b) of the valve as represented by the signal provided by the position sensor (30). After driving the actuator (40) with one such drive pulse, the generation of the next subsequent drive pulse is inhibited by a pause unit (75) for a predetermined period of time.

Abstract: An interrupt service routine (14) monitors the data to the processor (12) received from a printer (10) in response to control instructions sent by the processor (12). When an exception condition indicating that the printer (10) is no longer capable of fully carrying out processor instructions is received by the interrupt service routine (14), it activates an exception handler routine (15). A primary memory storage stack (21) normally supports the interrupt service routine (14). However, upon the activation ofthe exception handler routine (15), this primary storage stack (21) is switched to support the exception handler routine (15), and a secondary stack (23) of significantly lower storage capacity is placed in support of the interrupt service routine (14) which should have lower purported storage requirements during the active period of the exception handler routine (15). This results in a substantial saving of main processor memory capacity which otherwise would have to be dedicated to the support of the two respective routines.

Abstract: In a duplex optical transmission system in which the optical transmitter (3) and the optical receiver (2) of each terminal (1) of the transmission section are supplied from the same voltage source, the optical transmitter (3) and the optical receiver (2) of at least one terminal are connected in series with regard to the power supply, and the optical receiver (2) is combined with a booster circuit to form a receiver unit (13) whose power consumption is independent of the output voltage of the optical receiver (2). As a result, the optical transmission system is also suitable in a simple and cost-effective way for small feed currents and powers, and the transmitter output signal is not affected by fluctuations in the receiver output signal. A particularly expedient embodiment of the booster circuit consists in a current source (T2, R3), which is connected in parallel to the optical receiver (2) and is controlled correspondingly by the output voltage of the receiver (2).

Abstract: A digital mode phase modulation type position detector utilizing a resolver 20 as the phase modulating element is disclosed in which the phase of the modulated signal a is determined by comparing it 36 with that ofthe followersignal b, the phase of which is adjusted to that of the modulated signal. The phase difference between the modulated and the follower signal is detected at the ends of the half-periods thereof to effect the adjustment. To make the adjustment more precise, an adjustment circuit may further be provided which generates evenly spaced pulses in the present half-period of the follower signal at a frequency corresponding to the rotational speed of the resolver during the preceding half-period of the modulated signal. These pulses are used to adjust the phase of the follower signal more closely to that of the modulated signal. The position counter38 is also provided to accumulate the values corresponding to the phase differences between the modulated and the follower signal and/or the number of the pulses of the adjustment circuit. Thus, the accumulated value in the position counter represents the overall rotational angle of the resolver from the beginning of the counting up to the present instant.

Abstract: An improvement to a Viterbi-type decoder for decoding convolutional error-correcting codes whereby decisions regarding which predecessor state to a given state most probably corresponds to the best path terminating in that given state are stored in association with that given state and not in association with the best path. Paths are reconstructed by searching through such stored decisions. Such searches are used to recover a number, possibly greater than one of data symbols for later output from the decoder. The larger this number, the less frequently a search need be carried out.
