Title: Non-aqueous solvent secondary battery and its device
Inventor: GOTO AKIHIRO
IPC: H01M4/485
Filed: 1993-04-01
Abstract: PURPOSE:To increase life and predict life by constituting a positive electrode of a secondary battery by plural active materials of mutually different working potentials, thereby having a stepped, discharge-voltage curve, and predicting the point of reaching a voltage plateau as discharge termination, and so grasping accurately the remaining capacity. CONSTITUTION:In an Li secondary battery, the active material of the positive electrode is amorphous V2O5 added with a specified quantity of LiV3O5, so that voltage characteristic in constant-voltage discharge is a stepped one. Voltage of the battery 2 is measured with an ammeter 3 and voltmeter 4 and this information obtained is displayed on a display 8 via an operation controller 6. The point where a plateau in the second stage has appeared in the voltage curve is taken as predicting termination of discharge, so that the subsequent discharge is taken as a marginal discharge capacity. When the discharge reaches a set value of discharge stop, the circuit is cut off with a switch 5, when the discharge stop is displayed. Reliability in the prediction of a remaining battery capacity is thus raised, leading to its long life and accurate life prediction.

Filed: 1986-04-02
Abstract: PURPOSE:To eliminate the need for the change in the oscillating frequency at each channel selection operation by impressing an impulse signal using the same frequency as the channel interval of a broadcast band as a fundamental frequency as an adjusting signal to a receiver input terminal. CONSTITUTION:For example, a position change in a channel selection variable resistor is given to a tuning control circuit 9 as a voltage change, the tuning control circuit 9 changes over a switch circuit 10 to be a position Shown in figure, and changes gradually a reverse voltage of a tuning varactor diode inlcuded in a tuning amplifier circuit 2.

Title: Automatic frequency control circuit
Inventor: TANAKA HIROYUKI
IPC: H03L7/10
Filed: 1988-03-31
Abstract: PURPOSE:To shorten the lead-in time of a system by securing such a constitution where a phase frequency detector outputs two output error signals in accordance with the relation of frequencies between an output signal obtained by mixing two signals and a reference signal and a controller uses the two error signals to always keep the voltage control terminal of a voltage control oscillator under a negative feedback state. CONSTITUTION:An output signal f1 that undergone the conversion of frequency via a mixer 1 is inputted to a phase frequency detector 3 together with a reference signal fREF produced by a reference signal generator 2. Then two output error signals f1 and f2 received from the detector 3 are inputted to a controller 4. The controller 4 refers to the states of both signals f1 and f2 to apply such voltage to the voltage control terminal of a voltage control oscillator 5 so that this control terminal is always set in a negative feedback state. As a result, the signal f1 of the mixer 1 is always synchronized with a fixed frequency regardless of the frequency drift of an input signal fR. Thus the lead-in operation of a system is minimized.

IPC: H02M3/338
Filed: 1985-04-12
Abstract: PURPOSE:To stabilize the drive conditions by utilizing the constant voltage induced in a transformer of a blocking oscillator as the base drive power source of a transistor. CONSTITUTION:A power source circuit rectifies and smoothes an input voltage 1 by a bridge 2 and a capacitor 3, and produces the prescribed output through a blocking oscillator made of a main switching transistor (Tr) 5 and an oscilla tion transformer 37 from its output winding 9. In this case, the base auxiliary winding 11 and the output winding 9 of the transformer 37 are matched in the winding polarity to charge capacitors 17, 22 when the Tr 5 is OFF. Thus, the Tr 5 is started to operate by the ON of the power source, and the capacitor 17 is charged by the base winding 11. When the Tr 5 is turned ON, a base current is supplied from the capacitor 17 simultaneously with the base current from the base winding 10. The charging voltage of the capacitor 17 is constant voltage due to the blocking oscillator to supply the base current sufficiently at low input voltage time.
