Abstract: A control  voltage  coarse adjustment  circuit including a  D/A converter voltage generator is provided on a load side of a capacitor in a  loop filter included in  a phase  locked  loop.       For this  structure,  a coarsely adjusted voltage  is generated to be added to a voltage which is  generated by the capacitor of the loop filter  for   the  switch-over  of   channels  during  a communication frame.         The added voltages  are applied  to a  voltage controlled  oscillator to  change  a frequency  for  the switch-over of  channels.      Consequently, the  charge and discharge  of the  capacitor  is  carried out  in  a short time  to  suppress  the  influence  of  dielectric absorption current.    Thus,  the intermittent operation of the phase locked  loop in which the phase locked loop is  closed and opened intermittently is  carried out for the saving of electric power consumption, and a  carrier frequency is stabilized  in the open  phase locked  loop by an  electric charge voltage  of the  capacitor in the loop filter.

Abstract: A portable bathing unit for use with bedridden patients is disclosed.  The bathing unit includes a bath tub supported by a carriage which is movably positionable  in the proximity of a patient.  Casters depend from the bottom of the carriage housing to permit the portable bathing unit to be rolled along in an upright posture.  Additional casters are also attached to the rear of the housing which permit the portable bathing unit to be turned up on its rear and transported through narrow doorways.  Water delivery and retrieval is accomplished through the use of a submersible pump and a segment of conduit.  A whirlpool bath tub may be employed if desirable.

Abstract: A vehicular suspension system incorporates, at each wheel (14), a liquid spring (12) which internally utilizes a compressible liquid to generate spring and damping forces that yieldingly resist vertical wheel deflection relative to the vehicle frame. The liquid spring includes a dual piston assembly (36) which divides a main cylinder into bounce (38) and rebound (40) chambers. A rotary metering valve (80) is interposed between the bounce (38) and rebound (40) chambers for controlling the flow of compressible liquid from one chamber to the other during bounce and rebound. The dual piston assembly includes a tubular piston (48) having a modulation chamber (52) coupled in flow communication with the bounce chamber (38). The spring and damping characteristics of each liquid spring are computer adjusted during vehicle operation by modulating the bounce chamber pressure in response to sensed variations in various liquid spring and vehicle operating parameters.

Abstract: A GTL phased-output driver is provided which employs a pre-driver, a set of phasing elements or delay elements, and a set of output transistors. The pre-driver includes pull up devices, such as PMOS devices, and pull down devices, such as NMOS devices.  The PMOS devices of the pre-driver are configured to route output transistor-triggering signals through the phasing elements in one direction whereas the NMOS devices are configured to route output transistor-releasing signals through the phasing devices in an opposite direction.  Output transistors of differing sizes are employed.  During a pull down operation, controlled by the PMOS pre-driver transistors, the output transistors are triggered sequentially in order from smallest to largest.  During a pull up phase, controlled by the NMOS pre-driver transistors, the output transistors are released in a reverse order from largest to smallest.  Hence, the largest transistor is triggered first during a pull down phase but is released last during a pull up phase.  Within this configuration, improved edge rates and system noise levels are achieved. An edge rate control circuit is also describedwherein time delays provided by each of the phasing elements may be varied to thereby vary the triggering times of the output transistors to also vary the edge rate of the output signal. Test circuitry for allowing individual testing of theoutput transistors is also described.

Abstract: A high saturation current, low leakage, Fermi threshold field effect transistor includes a predetermined minimum doping concentration of the source and drain facing the channel to maximize the saturation current of the transistor. Source and drain doping gradient regions between the source/drain and the channel, respectively, of thickness greater than 300.ANG. are also provided. The threshold voltage of the Fermi-FET may also be lowered from twice the Fermi potential of the substrate, while still maintaining zero static electric field in the channel perpendicular to the substrate, by increasing the doping concentration of the channel from that which produces a threshold voltage of twice the Fermi potential. By maintaining a predetermined channel depth, preferably about 600.ANG., the saturation current and threshold voltage may be independently varied by increasing the source/drain doping concentration facing the channel and by increasing the excess carrier concentration in the channel, respectively. A Fermi-FET having a gate insulator thickness of less than 120.ANG., and a channel length of less than about 1.mu.m can thereby provide a Pchannel saturation current of at least 4 amperes per centimeter of channel width and an N-channel saturation current of at least 7 amperes per centimeter of channel width, with a leakage current of less than 10 picoamperes per micron of channel length using power supplies of between 0 and 5 volts.

Title: Method for producing an aromatic polycarbonate
Inventor: OKAMOTO HIROSHIGE
IPC: C08G64/20
Filed: 1994-07-21
Granted: 1997-11-04
Abstract: A method for producing an aromatic polycarbonate comprises introducing to an introduction zone (having a perforated plate) a) a molten monomer mixture of an aromatic dihydroxy compound and a diaryl carbonate, or b) a molten prepolymer obtained by a process comprising reacting an aromatic dihydroxy compound with a diaryl carbonate, and allowing the monomer mixture or prepolymer in the molten state to pass downwardly through the perforated plate and fall freely through a free-fall polymerization reaction zone, thereby effecting polymerization of the monomer mixture or prepolymer during the free-fall thereof. Colorless and high quality aromatic polycarbonates are thus stably produced at a high polymerization rate for a prolonged period of time, using an apparatus which has excellent sealing properties under high vacuum and maintenance of which is easy.
