Abstract: A wireless power supply system includes a plurality of power transmission units that receives and supplies power to a power receiving unit via the power transmission coil in a resonance state, and a switching control unit that switches a state of a first power transmission unit to a resonance state when the magnitude of the magnetic flux generated in a first power transmission coil of the first power transmission unit, which is one of the plurality of power transmission units, is greater than a predetermined threshold value, and switches to a non-resonance state when the magnitude is less than the threshold value. The threshold is set as a magnitude that exceeds the magnetic flux generated in the first power transmission coil due to coupling between the first power transmission coil and a second power transmission coil of a second power transmission unit, which is adjacent to first power transmission coil.

Abstract: A coincidence circuit for detecting when n-bit binary input data coincides with the current value of an n-bit counter. A plurality of "1" detecting circuits determine, when a corresponding input bit is one, whether a corresponding counter bit is also one. A first-coincidence detecting circuit determines the first time that all the "1" input bits have corresponding "1" clock bits. Each "1" detecting circuit includes an inverter and a NOR gate. The first-coincidence detecting circuit includes an OR gate and a latch circuit.

Abstract: In an image recording apparatus capable of recording a halftone image, a gradation to bit-train converting table converts gradation data representing a gradation of tone at a picture element of an image into bit-train data whose bit pattern is based on the gradation data. For the gradation data representing a gradation in excess of a threshold gradation, the table converts the gradation data into such bit-train data that bits of the bit-train data corresponding to the gradation data are intermittently omitted after a train of bits corresponding to the threshold gradation is outputted. A bit-train to pulse-train converting section converts the bit-train derived from the gradiation to bit-train converting table into pulse-train signal of a pulse pattern analogous to that of the bit-train data. The pulse signal of such a discontinuous pulse pattern is applied to a heating element of a thermal head, which is provided corresponding to the picture element whose gradation data is under process.

A picture element stores gradation data representing a plurality of picture elements to be recorded to reproduce a picture image. A gradation conversion mechanism receiving the stored gradation data and the stored resistance variation data associated with the recording elements to record the gradation data and corrects the values of the gradation data to compensate for the variations in the resistances of the recording elements from a predetermined value.

Abstract: A printing device in which pulses corresponding in number to gradations to be visibly expressed are applied to the heat generating elements of a thermal had in such a manner that the heat generating elements are controlled in heat generation time. Image data storing means stores, as a recording unit of image data, image data of picture elements which can be recorded in one action. Gradation-to-bit-train conversion means receive the image data from the image data storing means in units of picture elements, and output bit trains representing the numbers of pulses according to the gradation to be expressed.

Abstract: A thermal recording apparatus includes a comparator for comparing the black density of picture elements to be recorded by thermal recording elements to reference density levels, a counter accumulates a value representing the number of picture elements having density levels in certain ranges as a result of the comparison by the comparator. The counter value is used to adjust the pulse width of pulses used to energize the recording elements to compensate for fluctuations in the levels of the pulses due to the number of recording elements that are energized at one time and the durations of the energizations in order to record visible images of the picture elements with appropriate densities.
