Abstract: A locomotive throttle controller having a CPU and output driver stage.  Such CPU generates an analog voltage based on software logic and transmits to the output driver stage a signal indicative such analog voltage.  Such output driver stage receives the signal from such CPU and uses it to provide an analog output voltage signal to a trainline which monitors and/or controls dynamic braking.  The improvement therewith of an apparatus, for feeding back from such output driver stage to the CPU an analog signal indicating status of such trainline, comprising a device for obtaining a first analog voltage signal from a node which supplies current to such trainline.  A voltage-divider for dividing the first analog voltage signal into a lower range to obtain a second analog voltage signal.  A signal generating device connected to receive the second analog voltage signal and generate a third analog voltage signal.  A voltage to current converter receives such third analog voltage signal and provides a regulated electrical current signal on an output terminal thereof.  A conduction path between such output terminal and CPU is provided.  A converter in such CPU converts the electrical current signal into a fourth analog voltage signal.  A comparator in such CPU compares such fourth analog voltage signal with the analog voltage based on software logic and an error signal generator in such CPU generates and utilizes an error signal indicating inconsistency between such fourth analog voltage signal and the analog voltage based on software logic.

Abstract: Lipid-containing prodrugs are provided for treating viral infections duo to herpes, influenza, hepatitis B. Epstein-Barr, and varicella-zoster viruses, as well as cytomegalovirus and derivatives of antiviral agents. The compounds comprise phosphonoacids having antiviral activity which are linked, either through the phosphate group or carboxyl group of the  phosphonoacid, to one of a selected group of lipids. Phosphonoacetic acid and phosphonoformic acid are thus linked to phospholipids, glycerolipids, sphingolipids, glycolipids, or fatty acids. The compounds persist, after intracellular hydrolysis, as the antiviral phosphonoacids. The lipid prodrugs are effective in improving the efficacy of antiviral phosphonoacids by prolonging their antiviral activity following administration.

Patent CA-2157272-A1 (CA)
Inventor: MIKI YOSHINORI
IPC: H04B1/707
Filed: 1995-04-21
Abstract: A determinant expressing the relation between the sequence of symbol vectors b(k) transmitted from L communicators through code division multiplexing and the sequence of compressed-back output vectors y(k) of received signals taking the cross correlation of the spread-spectrum sequence of the sequence of the vectors b(k) into account is limited within the range of from k-g to k+g where k is the symbol timing and g is the symbol time. The compressed-back outputs of the received signals within the limited range are inputted to a shift register having 2g+1 stages. A partial correlation matrix calculating section (26) calculates partial correlation matrixes Rk+h (1), Rk+h (0), and Rk+h (-1) with respect to h=-g,..., g at every symbol interval within the limited range.  An inverse correlation matrix calculating section (27) produces the correlation matrix Rk for the spread-spectrum sequences which respectively corresponds to the L communicators from the partial correlation matrixes and calculates the inverse correlation matrix Rk-1 of the correlation matrix Rk. A  multiplier (25) produces an estimated sequence of symbol vectors by calculating the product of the inverse correlation matrix Rk-1 and the sequence Yk of the compressed-back outputs y(k) from the register (24).

Title: Apparatus and method for recording and reproducing a television signal
Inventor: KANOTA KEIJI
IPC: H04N7/00
Filed: 1995-11-03
Abstract: The television signal recording/reproducing system digitally records and reproduces television signals composed of a luminance signal, a chrominance signal and a resolution compensation signal included in predetermined television scanning lines. The system includes a Y/C separating circuit for separating the luminance signal Y from the chrominance signal C.      The luminance signal.Y and the resolution compensation signal are combined onto a first signal line.

Title: Transmitter-Receiver
Inventor: NISHIMURA SHUJI
IPC: H04B1/3822
Filed: 1995-11-15
Abstract: In a transmitter-receiver having a transmitting circuit and a receiving circuit, it is an object of the present invention to mitigate an interference between the transmitting circuit and the receiving circuit.  A quartz-crystal oscillator is provided as a common reference signal source for the local oscillators and the relation among frequencies is determined so that the frequencies such as local oscillating frequencies and intermediate frequencies within the transmitter-receiver do not overlap each other.          Interferences between the transmitting circuit and the receiving circuit are mitigated to prevent a characteristic deterioration, spurious radiation, etc.  Thereby the transmitter-receiver may be reduced in size and weight.          Further, by sharing a quartz-crystal oscillator having a high frequency stability, narrowing of bands in radio channel spacing may be readily achieved.
