IPC: H03L7/189
Filed: 1983-05-19
Abstract: PURPOSE:To improve carrier-noise ratio without narrowing down a usable oscillation frequency band by controlling one oscillation signal set by a programmable counter through a voltage-controlled oscillator (VCO) with its high-order digit signals and error signal. CONSTITUTION:The input side of a digital-analog converter 13 is connected to pin terminals D6 and D7 of a frequency division ratio setting circuit 10 for the high-order digits, and a digital value is inputted in binary mode and converted into an analog value, which is outputted as a digit signal VK to a terminal 12 of the VCO 11. The 1st - the 4th digit signals VK correspond to the 1st oscillation frequency bands W1, the 2nd oscillation frequency band W2.... When pin terminals D0-D7 are set to N=23 by the frequency dividing and comparing circuit 10, an error signal Vi is applied to a terminal 6. The digit signal VK is sent out to the terminal 12, so locking is performed at a point P2 on a curve b1. A frequency FL has small width of fine variation on the curve B1 centering on the point P2, and a carrier noise is improved.

Abstract: PURPOSE: To reduce the input current ripple of an inverter and prevent signal failure thereof by providing a function generator for generating a level signal,a triangular wave generator for generating a carrier signal having integer times frequency of the level signal, and a modulator for comparing and mixing both signals.  
     CONSTITUTION: A trigger pulse generator 9 synchronizes the output frequency of an inverter to generate a trigger pulse A 5  having extremely narrow pulse width at predetermined time. A function generator 10 is so constructed as to produce an output signal becoming time function from the initial value given with the trigger pulse A 5 , and is exponential functionlike generator of discharging characteristics of a capacitor C and a resister R. Such a configuration can sufficiently lower the output impedance of the pulse generator 9, thereby charging the capacitor C sufficiently to the initial value even if the pulse width is extremely narrow. An adder  11 adds the output of the function generator 10 and the level signal A 2  to generate  an exponential functionlike waveform A 6 . In this manner it can prevent the  signal failure.

Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To provide a mobile communication method for which the burden of jobs caused by the extension of a base station is relieved and the service is not stopped at the extension. SOLUTION: In the case that information representing a moving destination zone 2 is registered in a table of a base station of a source zone (newly installed zone) 1, the base station of the zone 1 gives information representing its own zone to a base station of the zone 2 and executed a hand-over step to designate a communication channel; after movement. On the other hand, in the case that information representing the moving destination zone 2 is not registered in the table of the base station of the source zone (newly installed zone) 1, a mobile station M gives the information representing zone 1 to the base station of the zone 2 and executes the re-connection hand-over to decide the communication channel after the movement by the base station of the zone 2.  Thus, when the base station is extended newly, the tables of both base stations in the newly installed zone 1 and existing zones 2, 3 are updated automatically.

Filed: 1986-04-21
Abstract: PURPOSE:To provide the titled inducing agent containing a urokinase precursor as a main component, capable of inducing tissue plasminogen activation factor by intravenous injection and useful for the promotion and continuation of fibrolytic activity. CONSTITUTION:The objective composition contains a urokinase (UK) precursor as a main component. The UK precursor is secreted from human kidney cell. Although it has no fibrolytic activity by itself, it is converted to UK by the action of plasmin, etc., to develop remarkable fibrolytic activity. A tissue plasminogen activation factor (TPA) can be induced by administering the UK precursor preferably by intravenous injection. Both UK precursor and TPA are proteins participating in fibrolytic activity, however, UK precursor is nonreactive with TPA antibody and TPA is nonreactive with UK precursor antibody. The dose of UK precursor is preferably 500,000-2,000,000 IU/day (in terms of UK). The concentration of TPA in blood is dependent on the dose of the UK precursor and the agent is useful for promoting and continuing fibrolytic activity.
