In the case of charging by a charging apparatus having a plurality of input terminals to which external power sources for charging a secondary battery are inputted, it is prevented that a current of the inputted power source is outputted to the outside from the other input terminals for charging which are not used. If there are inputs from a plurality of input terminals, the input power sources are controlled so that the battery is optimally charged. pnp-type transistors Q1 and Q2 are arranged between two input terminals of a terminal 11 for an external power adaptor and a terminal 12 for a holder and a secondary battery E1, respectively. When a control IC 13 detects an input power voltage of one of the transistors, the transistor on the detected side is turned on. If the control IC 13 detects both input power voltages, a priority is allocated under predetermined conditions and the secondary battery E1 is charged by the power source of the higher priority.
摘要:
A commercially available power source is rectified by a diode bridge and a capacitor and supplied to a transformer via a terminal. One end of a primary coil is connected to the terminal and the other end is connected to a switching device. One end of a feedback coil is connected to the switching device and the other end is connected to the terminal. A negative feedback circuit is provided between the switching device and the terminal. A rectifying circuit comprising a diode and a capacitor is provided on a secondary coil. A node of the coil and the capacitor is connected to the terminal via a resistor. In detecting circuits, a voltage across the terminal is detected and a current across the resistor is detected. When the detected voltage and current are equal to predetermined values, a control signal is supplied to a feedback circuit.

To provide a manufacturing method of the semiconductor IC device having fine-structure connecting holes or trenches with high dimensional precision. There is the following step of the operation: a hook-shaped hard mask made of polysilicon film 18 and polysilicon film 20a is formed on the surface of silica film 17 for forming connecting holes 21 accommodating plugs that perform an electrical connection with the lower portion of the lower electrode of the capacitor in the COB-type memory cells, with the hook-shaped hard mask being used as an etching mask in selective etching so as to form connecting holes 21 on silica film 17 and silica film 15 below it.
摘要:
In coordinate and surface texture measurement in which measurement control is performed by a part program, a part program is analyzed to extract measurement information or measurement condition. The measurement condition is rewritably stored such that optimal measurement conditions of an actual measurement can be reflected in a part program, and such that the actual measurement conditions can be added to subsequent measurement control.
