IPC: C04B35/65
Filed: 1989-01-03
Granted: 1993-07-12
Abstract: A net shaped ceramic-reinforced aluminum matrix composite is formed by forming a permeable mass of ceramic material (10) with a defined surface boundary having a barrier, and contacting a molten aluminum-magnesium alloy (20) with the permeable mass of ceramic material (10) in the presence of a gas comprising from about 10 to 100 % nitrogen, by volume, balance nonoxidizing gas, e.g. hydrogen or argon. Under these conditions, the molten alloy (20) spontaneously infiltrates the ceramic mass under normal atmospheric pressures until it reaches the barrier. A solid body of the alloy (20) can be placed adjacent to a permeable bedding of ceramic material (10) having a barrier, and brought to the molten state, preferably to at least about 700 DEG C, in order to form the net shape aluminum matrix composite by infiltration. In addition to magnesium, auxiliary alloying elements may be employed with aluminum. The resulting composite products may contain a discontinuous aluminum nitride phase in the aluminum matrix.

Title: Subscriber unit for wireless digital subscriber communication system
Inventor: CRITCHLOW DAVID N
IPC: H03D3/00
Filed: 1990-07-27
Granted: 1995-02-07
Abstract: A subscriber unit for wireless communication with a base station in a wireless subscriber communication system includes a FIR chip, a DIF (digital intermediate frequency) chip, a single processor chip and a radio. The processorchip transcodes a digital voice input signal to provide digital input symbols; demodulates an output signal received from the base station to provide digital output symbols; and synthesizes a digital voice output signal from the digital output symbols. The FIR chip FIR filters the digital input symbols and generatestiming signals for timing the transcoding and synthesizing operations in the processor chip. The DIF chip digitally synthesizes a digital intermediate frequency signal by direct digital synthesis (DDS) and modulates the digital intermediate frequency signal with the filtered input symbols to provide a modulated intermediate frequency input signal. The radio further processes the modulated input signal for transmission to the base station.

Title: Carrier regenerating device correctly operable in mobile satellite communication
Inventor: OTANI SUSUMU
IPC: H04L27/00
Filed: 1990-11-09
Granted: 1994-01-11
Abstract: ABSTRACT OF THE DISCLOSURE           Supplied  with  an  input  signal  into which  a carrier signal is modulated at a frame period by a data signal   and  unique  words   periodically   interspersed throughout  the  data  signal,  a  demodulating  circuit quadrature demodulates the input signal into an output signal.   A cross-correlating circuit calculates a cross-correlation coefficient between the output signal and a locally known unique word.  A frame synchronizing circuit compares   the   cross-correlation   coefficient  with   a predetermined threshold value and delivers an aperture when the   cross-correlation   coefficient   is   below   the predetermined threshold value.  A phase calculating circuit calculates phase errors between a recovered carrier signal recovered from the output signal and a regenerated carrier signal which is a correct reproduction of the carrier signal.  The phase errors are set in a carrier regenerating circuit to render the recovered carrier signal identical with  the  regenerated  carrier  signal  at  the  aperture interval.   Preferably,  a frequency calculating circuit calculates frequency errors between the recovered and the regenerated carrier signals for use in making the recovered carrier  signal  identical with  the  regenerated  carrier signal not only as regards phase but also as regards frequency.

Title: Stabilized fluorescent lamp for a document scanning system
Inventor: BRANDKAMP WARREN F
IPC: G03B27/72
Filed: 1991-08-08
Granted: 1997-04-29
Abstract: A fluorescent lamp utilized in a document scanning system is environmentally and thermally stabilized by means of a bifurcated heater control assembly. A heater blanket is wrapped around the entire surface of the lamp including the end areas surrounding the filaments but exclusive of the aperture through which light is emitted. The size and temperature of the lamp cold spot are selected emperically to maximize output power and minimize illumination transients during power on. The heater jacket has thermostat control set points which, in both the lamp standby and energized states, maintain the blanket and lamp assembly at a constant elevated temperature which is above that achieved by lamp heat alone. Since the temperature distribution is always determined by the blanket and never by the lamp, changes in temperature or temperature distribution (and hence illumination distribution) as the lamp transitions from standby to full on are minimized.
