Title: Switching power source
Inventor: YANAGISAWA RYUICHI
IPC: H02M3/28
Filed: 1987-12-03
Abstract: PURPOSE:To prevent the excessive stress on a main switching element and the overshoot of an output voltage by applying an output DC voltage to a time constant circuit comprising a capacitor and a resistor in a soft start circuit to make a rise slower without increasing a time constant. CONSTITUTION:When a starting signal is fed to an input terminal 10, a transistor(Tr) Q2 is turned OFF, a voltage VE at the - terminal of a comparator 13 lowers, and a peak voltage of a triangular wave oscillating circuit 2 is applied to the + terminal thereof. Consequently, a switching Tr Q1 is turned ON and a voltage V0 appears at a DC output terminal 9. In this case, when a soft start circuit 1 is a light load, a capacitor C2 is charged to the voltage V0 and a voltage at the - terminal of a comparator 12 lowers gradually. As a result, when a triangular-wave voltage is higher than the voltage in a comparator 15, the triangular wave voltage becomes a rectangular wave voltage to drive the switching Tr Q1. When a heavy load is connected with the terminal 9, the voltage at the - terminal of the comparator 13 lowers to a voltage necessary for turning the switching Tr Q1 ON.

Abstract: PURPOSE:To suppress error propagation in a unit rectangle even when an error is caused and to limit a loss within a high frequency component loss even when data quantity is too much to be stored in the range by making the data quantity in the prescribed rectangle unit identical and recording the data. CONSTITUTION:As an example of data, 2n sets of rectangle units obtained at an orthogonal transformation means 2 are referred to as A1, A2...An, B1, B2...Bn, and a high frequency component is arranged to a sink 3: When rectangle units having very much information quantity are concentrated, the data cannot be stored in the sink 3. Excess units are referred to as B'm+1 to B'n. However, they are high frequency components, the entire pattern is reproduced. When the pattern is reproduced, the components below the B'm+1 are thrown away and an EOB representing the end is added. Thus, even in the case of high speed reproduction, the reproduced pattern is adopted for wider range and a new data is revised.
