Title: Digital modulator
Inventor: HARRIS ROBERT M
IPC: H04L27/20
Filed: 1989-01-19
Granted: 1991-09-24
Abstract: ABSTRACT                            DIGITAL MODULATOR       Signal modulation apparatus for the transmission of binary data signals embodying a process which results in superior side-lobe suppression compared with other forms of modulation such as frequency shift keying.  The apparatus generates two carrier waves, the difference between whose frequencies Is an integral multiple of the data signal bit-rate, amplitude modulates the two waves by a low-pass filtered data signal and an inverted version thereof respectively and then sums the resulting modulated waveforms to produce a frequency keyed waveform having continuous phase and almost negligible envelope ripple.  The apparatus can be used with most forms of digital communication systems and may be demodulated by a conventional receiver such as ratio detector or phase-locked loop.

Title: Apparatus for detecting frequency of input signal with a digital scanning g-converter
Inventor: ANDO NAOTAKA
IPC: G09G5/12
Filed: 1989-02-28
Granted: 1993-01-26
Abstract: ABSTRACT OF THE DISCLOSURE         A frequency detector is used with a digital scanning converter that enables a monitor receiver having a particular horizontal deflection frequency to monitor various video signals having various horizontal frequencies.          The frequency detector has a counter for counting a reference clock during a predetermined time interval derived from an input signal to be measured and a computing circuit for adding or subtracting a first constant to or from a setting cycle in response to a difference between a count value of the counter and the setting cycle.  When the difference between the count value and the setting cycle exceeds a second constant during a predetermined number of such time intervals, the setting cycle is adjusted by an output from the computing circuit, and an approximate value of a cycle of the signal to be measured is computed, thereby detecting the approximate frequency.  This process goes through as many iterations as necessary to bring the difference between the count value of The counter and the setting cycle to a value less than the second constant.          Even when the frequency of a signal to be measured has a value selected from a number of values that differ greatly from one another, the frequency detector thus homes-in on the period of the signal to be measured and enables detection of the frequency with high accuracy.  Also, even when pulse dropouts or time base fluctuations occur in the signal to be measured, the frequency detector can obtain a stable detected value.

Abstract: Abstract A pharmaceutical composition for use in inducing cell differentiation of leukemia cells in a patient. The composition employs seco-sterol compounds which are similar in structure to known vitamin D compounds since they contain the identical ring structure or nucleus, but are different in that they contain a shortened side chain comprising a hydrogen, methyl, ethyl or propyl attached at the carbon 20 position. Functionally. the seco-sterols do not express the classic vitamin D calcemic activities in vivo. The seco-sterols thus may be administered to cause differentiation of malignant cells to normal cells without producing simultaneously unphysiologically high and deleterious blood calcium levels.

Abstract: The invention relates to the regulation of the power of the power amplifier in a radio telephone transmitter at the time of tuning, in connection with manufacture, the power levels to comply with the specifications. The prior-art methods involve problems of controlling, in accordance with the specifications, the power leading and trailing edges at all power levels. There are difficulties especially at low power levels, at which the resolution is low because the measured voltages of low power levels are close to each other. In the present invention the regulation of the power amplifier (1) power is effected by using, for example, a comparator (5) one input of which receives the voltage obtained from the detector measuring the output power of the amplifier (1), the voltage having been attenuated in a controllable attenuator (3), and to its other input there is connected a reference voltage which can be regulated within an operating range ( DELTA V) whereby the voltage range ( DELTA V) is entirely, or for a major part, available for each power level of the telephone output level. The reference voltage is preferably formed by using a D/A converter (4). <IMAGE>

Abstract: Disclosed is a rock drilling apparatus and method for using same wherein the rock drill is a cluster of independent rock drills arranged in a circular pattern about a central axis for rotation. The cluster drill is drawn into a hole to be drilled by a drill string in a previously drilled smaller diameter hole.  The drill string provides pressure fluid to operate the cluster drill and rotation as well as the tractive force to draw the cluster drill into the hole to form a large diameter straight drilled hole.  Pressure fluid and rock cuttings exit the larger diameter hole and discharge of rock particles is further aided by use of a trailing auger rotated by the cluster drill.  A particular application of this device is in the production of horizontal bored holes of moderate diameter under, for example, roadways, foundations, and the like. The drill string acting as a centering device produces a straight hole in difficult rock formations.
