Title: External synchronizing method and apparatus for information transmission system
Inventor: KANETA YOSHIO
IPC: H04N5/073
Filed: 1984-08-13
Granted: 1987-12-15
Abstract: ABSTRACT In an information transmission system including transmitters, a receiver, and a transmission line for transmitting information signals from the transmitters to the receiver, the transmission line is shared by the information signals and external sync signals which are adapted to synchronize the transmitters to each other. The external sync signals have a voltage level higher than a maximum voltage level of the information signals or lower than a minimum voltage level of the same, and are transmitted to the transmitters over the transmission line by using blanking level Portions of the information signals. The external sync signals are separated from the information signals based on their level difference and, then, applied to the transmitters. Amplifier circuits for blocking the propagation of signals toward the transmitters are installed in the transmission line, while bypass circuits are connected to the transmission line each in parallel to the associated amplifier circuit so as to allow only the external sync signals to be transmitted toward the transmitters based on a signal voltage level.

Abstract: ABSTRACT A process for producing lower average molecular weight products from heavy liquid hydrocarbons is pro-vided comprising contacting the feed material in the presence of a co-catalyst system comprising a molten salt of sodium tetrachloroaluminate (NaAlCl4) and hydrogen tetrachloroaluminate (HAlCl4) at a pressure of from about 0.8 to about 140 atm (81 to about 14185 kPa) and a tem-perature of from about 200°C to about 550°C.      According to the present invention use of the HAlCl4 as a co-catalyst with NaAlCl4 results in increased yields of lower average molecular weight products and improved levels of denitrogenation and desulfurization.  The elements of the co-catalyst system may be prepared separately and mixed.

Abstract: ABSTRACT                        A Cutting Instrument A cutting instrument is formed of a single elongated strip (12) of resiliently flexible material having a bend (14) substantially midway in its elongation to define first and second shanks (16, 18) respectively, carrying a blade (20) and a shearing portion (28) at their corresponding ends.  The blade includes a cutting section (22), and the shearing portion includes a cutting edge (30), and the blade and shearing portion are pivotally connected (32) for movement of the cutting section and cutting edge toward and away from each other along a cutting plane.  In one embodiment an elongated suture gripping element (50) unitarily depending from the shearing portion includes a contact area (54) for suture gripping contact with the cutting section during an operating stroke or jaw closure of the instrument.  In another embodiment there is a cutting blade and a shear blade forming a scissors, with each blade having an elongated raised rib, and an abutment shoulder.  The ribs render the blade tips inflexible and bow the blades relative to each other, in order to provide edge-to-edge contact between the blades.

Abstract: Abstract of the Disclosure A control device for controlling temperature conditioning apparatus is connected to a thermostatic switch means having a circuit requiring a small current to maintain the circuit active during the open cycle of the thermostat switch means.  A positive temperature coefficient resistor is placed in parallel with the input circuit of the control device to provide a low input impedance to the control device for maintaining the small current without activating the control device.  During the operation of the thermostat with the switch closed, a larger current to the positive temperature coefficient resistor causes the resistor to increase in temperature and thus its impedance so the wattage dissipated by the PTC resistor is reduced to minimize the heat dissipation and thus the temperature of the control.

Abstract: NON-INVASIVE BLOOD FLOW MEASUREMENTS UTILIZING AUTOREGRESSIVE    ANALYSIS WITH AVERAGED REFLECTION COEFFICIENTS     Abstract A system for non-invasively determining the amount of blood flow within an internal patient blood vessel by performing an autoregressive analysis of Doppler shifted acoustical signals resulting from the reflection of ultrasonic signals due to blood cell movement by averaging the reflection coefficients and residual energy levels resulting from the autoregressive analysis over a number of cardiac cycles.  Each cardiac cycle is determined by an analysis of the patient's electrocardiogram signals, and the resulting cardiac cycles are divided into a predefined number of time segments or channels.  An autoregressive analysis is then performed on each individual channel to determine the reflection coefficients and the residual energy level for each channel.  The reflection coefficients and residual energy level for each particular channel are then averaged over all the cardiac cycles to obtain an averaged reflection coefficient and averaged residual energy level for each combined channel.  The power spectrum for each combined channel is then calculated from the averaged reflection coefficients and averaged residual energy level and displayed on a channel-by-channel basis utilizing different colors to represent the different power levels.  The utilization of different colors greatly enhances the usability of the display by medical personnel making diagnostic decisions regarding the amount of blood flow.
