摘要:
In the nonmagnetic Zn-ferrite of the present invention comprising iron oxide and zinc oxide, the content of Fe2+ is specifically limited. Alternately in the nonmagnetic Zr-ferrite comprising iron oxide and zinc oxide as main components, a given amount of at lease one metal oxide selected from the group consisting of manganese oxide, nickel oxide and magnesium oxide is contained. It is thus possible to provide a nonmagnetic Zn-ferrite that can have high resistivity without containing Cu.

There can be provided an NiCuZn-based ferrite material containing an iron oxide, a copper oxide, zinc oxide and a nickel oxide in predetermined amounts as main components and a bismuth oxide, a silicon oxide, magnesium oxide and a cobalt oxide in predetermined amounts as additional components. Due to the predetermined amounts of the additional components, the ferrite material has an extremely good temperature characteristic (a change in permeability along with a change in temperature is small), a high quality coefficient Q and high strength.

This invention offers a power supply circuit that is capable of improving a power factor as well as reducing a ripple current of an input/output of the power supply circuit due to switching of a switching device. The power supply circuit is provided with a first power supply circuit including first and second switching devices, a second power supply circuit including third and fourth switching devices and a switching control circuit. The switching control circuit controls the switching devices so that the first switching device and the third switching device are turned on and off at timings different from each other when an alternating current voltage from an alternating current power supply is positive, and the second switching device and the fourth switching device are turned on and off at timings different from each other when the alternating current voltage is negative.

An electrostatic discharge protection circuit has a bipolar transistor which includes a first diffusion layer of a first conductive type connected with a first power supply and functioning as a base; a second diffusion layer of a second conductive type connected with a second power supply and functioning as a collector; and a third diffusion layer of the second conductive type connected with an input/output pad and functioning as an emitter. An area of a first region of the third diffusion layer which is opposite to the first diffusion layer is larger than an area of a second region of the second diffusion layer which is opposite to the first diffusion layer.

An LCD (21) for displaying a plurality of set information items is provided for a digital camera (10). When a plurality of input keys disposed around the LCD (21) are depressed, set information which is displayed adjacent to the input key can be changed. A control portion of the digital camera (10) performs a variety of control operations of the digital camera (10) in accordance with set information. Therefore, the position of the input portion which is used when the setting of the digital camera (10) can easily be understood. Thus, the setting can be changed by performing only a simple operation.

A liquid crystal display driver includes a first selecting circuit configured to select a voltage from a first voltage range based on a digital signal; and a second selecting circuit configured to select a voltage from a second voltage range based on the digital signal. A voltage which is applied between a diffusion layer and a back gate of a first MOS transistor contained in the first selecting circuit is smaller than a voltage which is applied between a diffusion layer and a back gate of a second MOS transistor contained in the second selecting circuit. Also, an offset length of the first MOS transistor is shorter than that of the second MOS transistor. The liquid crystal display driver may further include a voltage generating circuit configured to supply gradation voltages of the first voltage range and the second voltage range to the first and second selecting circuits. One of the first and second selecting circuits outputs one of the gradation voltages based on the digital signal.
