Inventor: KADONO TETSURO
IPC: B01L3/16
Filed: 1990-08-20
Abstract: An apparatus (10) for gas/liquid separation has a heat-exchanging condensor housed in an adiabaic coolant container (30), in combination with an adiabatic reservoir (50) for the condensed liquid. The condensor has an inner pipe conduit (34) for a passive coolant which circulates through the conduit, and the container (30) and is cooled by a freezer coil (40) of an outside refrigerator and effectively cools the solvent vapor travelling through a clearance formed between the inner side wall of said condensor and outer side wall of said inner pipe conduit. This feature enables a continuous operation without troublesome replenishing of an active component in a freezing mixture as an active coolant. The adiabatic reservoir (50) receives the condensed liquid and has a visual gauge for monitoring. A communicating plug detachably provided on the shoulder of the adiabatic reservoir (50) serves to supply an auxiliary freeze-protecting solvent into the reservoir, for easy treatment of a solvent which is liable to be solidified by excessive cooling.

Abstract: In order to switch high loads, an off-delay relay (A) with arc-resistant contacts (a1, a2) and an on-delay relay with highly conductive contacts (b1, b2) are connected in an energising circuit, while their contacts are connected in parallel in the load circuit. When the energising voltage is applied, the first relay (A) thus responds first; when the energising voltage is interrupted, this first relay is the last to switch off so that its arc-resistant contacts in each case take over the switching-on and switching-off current, while in operation itself, the low-resistance contacts of the second relay (B) carry the major part of the current. <IMAGE>

Abstract: In a mobile telephone system, a base station establishes a radio link to a mobile station and a connection to a switched telephone network when the mobile station is in communication with a network-side station. The base station constantly monitors signals from the mobile station over the radio link. If it detects that the radio link is failing during a communication, a prerecorded announcement is transmitted to the network-side station. A recording/playback apparatus is then operated to record a message from the distant station. The base station further includes a ringing detector for detecting a ringing signal from the network. A connection is then established to the network from the base station if it fails to access the mobile station. A prerecorded announcement is then transmitted to the distant station and the recording/playback apparatus is operated to record a message from the distant station.

Title: A general purpose low cost digital amplitude regulator
Inventor: KUTZAVITCH WALTER G
IPC: H03G3/00
Filed: 1990-12-07
Abstract: Apparatus for digital amplitude regulation is disclosed, for use as a volume control or the like, utilizing pulse width modulation to control gain through the variation of the incremental resistance of a two terminal non-linear element (46), the resistance of which varies with current, e.g., a diode or diode like element. A stream of pulses, (from 12), the duty cycle of which is variable and digitally controlled, is filtered to produce a quasi-continuously variable direct-current (DC) voltage (at 22). The DC voltage either directly or by providing a DC current regulates the gain of an amplifier (26) for amplifying the signal of interest by regulating the transmission characteristics of the diode. For low cost implementation in a system already employing a microprocessor or microcomputer the determinative duty cycle can be derived under software control and supplied as an output from a single latchable output pin (13). 
     In an exemplary implementation, the incremental resistance of an ordinary silicon diode is operated in accordance with the small signal model of a diode. Additionally, the use of an energy storing type filter (14,16,18,20) allows the continuous stream of variable duty cycle pulses to be momentarily interrupted so that a pin (13) used for supplying the pulses can be used for the performance of additional functions without affecting the perceived volume level.

Abstract: The invention relates to a load adjusting device for a throttle valve-controlled internal combustion engine, with which the throttle valve (4) can be acted on on the one hand via an accelerator pedal-side control element (8) and on the other hand via an electromotive control drive (12), their movements being decoupled. In order to be able to detect both the idling position of the accelerator pedal-side control element (8) and thus the driver's desire to "idle", and in addition the actual position value of the electromotive control drive (12) for the positional control-circuit and the throttle valve position for the injection electronics, the invention proposes that a drive potentiometer (25) assigned to the electromotive control drive (12) and a throttle valve potentiometer (24) assigned to the throttle valve (4) be provided which have a common carrier plate (19) which is connected fixed in terms of rotation to the drive shaft (11) of the electromotive control drive (12) and has two slider tracks (21, 20), in which case one slider (21) for the drive potentiometer (25) is attached fixed to the housing and one slider (20) for the throttle valve potentiometer (24) is connected fixed in terms of rotation to the throttle valve-side control element constructed as a throttle valve shaft (5). The solution described does not require a separate idling contact in order to detect the LLmin position of the accelerator pedal-side control element (8). A further solution proposes that the two potentiometers be assigned to different carrier plates, in which case one of the carrier plates interacts with the drive shaft of the electromotive control drive and the other carrier plate interacts with the accelerator pedal-side control element. …<IMAGE>…

Abstract: A timing circuit in which an output can be held at a certain level or state for a particular time after the circuit is enabled. The time is established by an external resistor and capacitor. The timing circuit is self-biasing to permit operation after associated power supplies have dropped to zero. The timing of the circuit is independent of supply voltage and substantially independent of temperature variations. The timing circuit includes a number of MOSFET's which are diode connected between two nodes, and another MOSFET having a gate and one conduction electrode connected across the two nodes. The voltage between the two nodes at the beginning of the timing interval is the sum of the threshold voltages of the diode connected MOSFET's. At the end of the timing interval, the voltage between the two nodes has fallen to the threshold voltage of the single MOSFET. The timing interval is therefore dependent upon the discharge rate set by the external resistor and capacitor and the ratio of the sum of the threshold voltages of the plurality of MOSFET's to the threshold voltage of the single MOSFET. Relatively long time intervals can be achieved using this circuit with standard surface mount components for the resistor and capacitor. The circuit finds particular use in a disk drive in which a head actuator must be braked for a period of time and then retracted, with the period of time determined in an environment where the disk drive power supplies are falling to zero.
