Title: Mobile antenna system
Inventor: NISHIKAWA KUNITOSHI
IPC: H01Q1/32
Filed: 1990-12-06
Abstract: In mobile communications, it is required that the beam direction is maintained to track the desired direction as the mobile is moving. For such a purpose, the mobile includes an angular rate sensor mounted therein which detects the state of turn in the mobile and to control the beam direction of the antenna in accordance with the state of turn as well as the strength of radiowave received by a receiver in the mobile. Antenna elements (114) are in the form of microstrip antenna and are arranged in plane on the same dielectric substrate (113 or 112). Feeding and drive circuit layers (122, 124) for controlling the transmission and reception at the antenna elements are stacked into a single layered unit. This enables the antenna system to be formed into a low-profile structure. The dielectric substrate of the microstrip antenna element is formed by stacking a plurality of dielectric substrates (112, 113) different in dielectric constant from one another. It is thus intended that the band width of the antenna is increased and that the mutual coupling between the antenna elements is reduced to prevent the gain of the antenna from being lowered. Furthermore, the position of feed points in the antenna element are rotated against each adjacent antenna element. This can improve the axial ratio in the array antenna over a wide band width.

Abstract: A device for modifying the dynamic range of input signals includes a voltage divider formed by a fixed impedance (14) connected to one end of a variable impedance (16), e.g. an FET, controlled by a control signal. The control signal is provided from the output of the voltage divider  via  a buffer amplifier (36), rectifier (62) and smoothing circuit (63). In order to reduce the effect of the non-linear response of the variable impedance, its other end is connected to a potential derived as a fraction of the voltage divider output by way of an impedance (42) and buffer amplifier (38). This impedance (42) and an impedance (64) in the main control signal path may optionally be controlled by a signal derived from the input signal  via  a filter (52), rectifier (54) and smoothing circuit (56) so as to increase the bootstrapper effect on the variable impedance (l6) and increase the effect of the main control signal at high input signal levels.

Abstract: A method for conversion of comminuted cellulosic agricultural wastes into a form edible by ruminant animals comprises treating such wastes, e.g., straw, corn husks, cotton wastes, peanut shells, saw dust, etc. by spraying with an aqueous solution of a mixed oxidant gas, at a pH of about 11 - 12, to produce a water content of less than 40% and a pH of about 11.4 - 11.7 in the waste. The mixed-oxidant gas is preferably produced by a gas generator comprising an electro­lytic cell having an anode compartment, a cathode compartment and a membrane separating the compartments to permit only a limited flow of electrolyte therebetween. When a low salt concentration solution is electrolyzed in this cell, the output is a mixed oxidant gas containing chlorine and various oxygen-containing species. Another gas generator which may be used is that shown in U.S. Pat. No. 4,248,681. The oxidant gas produced from dilute salt solutions contains chlorine, chlorine dioxide and other oxygen-containing gases. After a reaction time from several hours up to several days, the product obtained is essentially free from chemically combined lignins and has been substantially hydrolyzed to sugars, and is a satisfactory feed for ruminant animals. Alternatively, the wastes may be treated with aqueous caustic to the desired pH and water content and the mixed oxidant gas circulated through the waste and absorbed therein.

Abstract: Image data is recorded in successive turns on a rotatable record medium driven at substantially constant linear velocity by converting a first of successive image frames of image data to an intraframe code signal, converting the (n-1) next-following frames to (n-1) interframe code signals, and recording the intraframe and (n-1) interframe code signals on the record medium. In one embodiment,  n  is the maximum number of image frames that can be recorded in the innermost turn of the record medium and  n  is constant for all turns, whereby the same number (n-1) of interframe code signals separate successive intraframe code signals from turn to turn. In another embodiment,  n  is a variable and increases as the radius of the turn in which the code signals are recorded increases, whereby a larger number (n-1) of interframe code signals separate successive intraframe code signals as the turn radius increases. The recorded image data is recovered by reproducing the recorded intraframe and interframe code signals and selectively coupling the reproduced code signals to an intraframe decoder or to an interframe decoder as a function or whether intraframe or interframe code signals are reproduced.

Abstract: In the apparatus an x-ray tube (A) is powered by a control circuit (C) for selectively irradlating a sheet of x-ray film (B). An operator selects the operating anode current mA for the x-ray tube, an exposure or dose value (preferably an mAs value), and a tube voltage kV on a keyboard (20). For a fixed operating voltage and selected mAs value, the film should be exposed to the same density regardless of whether a low mA and a long time or a high mA and a short time are selected. Particularly in single phase inverter control circuit and power supplies, the high current and short time exposures tend to be underdeveloped relative to low mA and long time exposures for the same mAs value. To standardize the exposure for any current and time combination of the selected mAs value, a look up table (60) is provided. The look up table is addressed by the selected kV, mA, and mAs values to retrieve an appropriate current boost value which boosts the actual current such that the film is exposed to the selected density. The current boost value is added (42) to the selected current such that the x-ray tube is operated or boosted above the selected anode current by the appropriate amount for the x-ray film to be exposed to the same density for all mA and time combinations corresponding to the same mAs value. Alternately, exposure time may be lengthened to achieve the correct dose.

Abstract: All of the resistors in a magnetic field sensitive circuit, both magnetoresistors (MRs)and fixed resistors (FRs), are formed simultaneously in a common fabrication process from a common magnetoresistive material. An additional structure in the form of Hall shorting strips is applied to selected resistors to rendered them MRs, while the resistors without the additional structure function as FRs. In one circuit the resistors are arranged in pairs in two voltage divider circuits. The high voltage resistor from one circuit and the low voltage resistor from the other circuit are MRs while the remaining resistors are FRs, producing an increased magnetic sensitivity. In another circuit all resistors are MRs and are positioned so that the magnetic field at one pair swings in a direction opposite to that of the other pair, further increasing the magnetic sensitivity. Discrepancies stemming from temperature coefficient mismatch and manufacturing variations are substantially reduced.
