Abstract: A charger control apparatus includes a total current acquisition unit and a setting unit to control a plurality of chargers connected in parallel with each other and supplied with a current from a common wiring line. An upper limit value of a current flowing through the wiring line is described as a first upper limit value. The total current acquisition unit acquires a total value of a current flowing through the plurality of chargers. The setting unit sets, for each of the plurality of chargers, a second upper limit value being an upper limit value of a current flowing through the charger by using the first upper limit value. When a difference between the total value and the first upper limit value satisfies a reference, the setting unit updates the second upper limit value for each of the plurality of chargers by distributing the difference according to a first rule.

Abstract: A salt composition is provided for the purpose of preventing excess intake of salt (sodium chloride) and achieving well balanced intake of minerals. The composition which is used in place of conventional table salt consists essentially of 100 parts by weight of a mixture containing 30 to 75% by weight of table salt and 25 to 70% by weight of potassium chloride being admixed with 5 to 60 parts by weight of a citric acid salt, e.g. tripotassium citrate. Seasonings, such as soybean paste and soy sauce, and foods, such as pickles and kimchi, can be prepared with such salt composition.

The composition which is used in the place of conventional table salt consists essentially of 100 parts by weight of a mixture containing 30 to 75% by weight of sodium chloride and 25 to 70% by weight of sylvinite admixed with 5 to 60 parts by weight of a citrate. Seasonings, such as soybean paste and soy sauce, and foods, such as pickles and kimchi, can be prepared with such a salt composition.

Abstract: A baseband signal communication apparatus includes a transmission unit and a reception unit. The transmission unit superposes a subcarrier on one value of a baseband signal consisting of binary values, modulates a carrier with the baseband signal on which the subcarrier is superposed, and transmits the baseband signal as a transmission signal wave. The reception unit demodulates the baseband signal having the subcarrier superposed thereon by using a demodulator upon reception of the transmission signal wave, extracts the subcarrier from the demodulated signal by using a bandpass filter, and demodulates the baseband signal by causing a detector to detect an envelope of the subcarrier.

Abstract: In a microwave electric power receiver, a microstrip resonator having a line length 1/2 of a wavelength of a microwave to be received is notched to be split at its longitudinally central portion into two portions. A rectification diode is interposed between notched end portions of the microstrip resonator portions to be matched therewith. The diode generates a DC power.

Abstract: A microwave responder resonates or does not resonate with a microwave transmitted from a radio transmitter, and radiates the resonated microwave as a response signal wave. Two microstrip lines are linearly arranged to be separated from each other at a predetermined interval. A diode which is switched between ON and OFF states in response to the response signal is interposed between two end portions of the microstrip lines separated by the predetermined interval, and a distance, between distal ends of the two linearly arranged microstrip lines, which includes an impedance defined by the ON or OFF state of the diode is determined to be 1/2 a wavelength of the microwave.

Abstract: A full duplex transponder system includes an interrogation apparatus and a transponder apparatus. The transponder apparatus includes a reception antenna for receiving an interrogation signal wave whose carrier wave is phase- or frequency-modulated with an interrogation signal, a demodulator for demodulating the interrogation signal from the interrogation signal wave received by the antenna, a rectifier for rectifying the carrier wave of the interrogation signal wave received by the antenna and outputting a DC power used as a drive power source of the transponder apparatus, a multiplier for generating a predetermined harmonic component from the carrier wave of the interrogation signal wave received by the antenna, a modulator for amplitude-modulating the harmonic component with a response signal, and a transmission antenna for transmitting a response signal wave output from the modulator.

Abstract: A robot vehicle for automatic operation in a predetermined travelling route comprises a pair of driving wheels connected to a driving device; means for detecting revolving speeds of said driving wheels; means for detecting azimuth of the travelling direction of said robot vehicle; a memory device for memorizing a travelling program including data of a travelling distance and an azimuth; and a control processor device which control the travelling of said robot vehicle depending upon the travelling program of said memory device under comparing the travelling distance and azimuth of the travelling program with a travelling distance detected by said revolving speed detecting means and an azimuth detected by said azimuth detecting means.
