IPC: H02M3/155
Filed: 1987-07-31
Abstract: PURPOSE:To improve the conversion efficiency at the time of light load by setting a converter action at said time in the state of blocking oscillation. CONSTITUTION:A DC-DC converter is composed of an oscillating transistor(Tr) Q1, a bias current source I1, a booster coil L1, a DC cut-off capacitor C1, a detection diode D1, and a smoothing capacitor C1; and is also equipped with a maximum voltage detecting element 2, a minimum voltage detecting element 3, a switching element 4, and a negative feedback element 5. When a switch SW1 is ON, TrQS3 is turned ON so that the bias current source I1 is also turned ON to bias the base of the TrQ1. The maximum voltage detecting element 2 is turned ON with the ON-state of the switch SW1 to keep the booster voltage V0 of the converter 1. Thus, an oscillating circuit is stopped at the time of light load and a blocking oscillation is made so that the load is driven by a charge stored in the capacitor C2. At the time of heavy load, the oscillating circuit is oscillated continuously.

Filed: 1990-07-17
Abstract: PURPOSE:To simplify a circuit, to reduce the cost and to miniaturize a device by performing correlative arithmetic between two screens by using a table and performing addition as the accumulation of electric charges. CONSTITUTION:Signals of picture elements of the screens are sent to analog/ digital converters 1 and 2 and the analog signals of the picture elements are digitized and stored in storage devices 3 and 4. When the pixel signals are calculated as data, values, etc., obtained by multiplying two numbers consisting of, for example, eight bits are stored as the table in a read-only memory 11 in advance and the result of the arithmetic is read out of the table. Data are read out, one after another, and converted by a digital/analog converter 12 into an analog signal, which is converted into a proportional current to accurate electric charge in an electric charge accumulation device 13 one after another. Thus, the correlative arithmetic between the two screens is performed by using the table and the addition is performed as the accumulation of the electric charges. Consequently, product arithmetic can be performed with one clock and the processing is speeded up.
