摘要： A Schottky barrier diode in which a p+-type semiconductor layer is provided in an n−-type epitaxial layer can realize lowering the forward voltage VF without considering leak current IR. However, when compared with a normal Schottky barrier diode, the forward voltage VF is generally high. When a Schottky metal layer is suitably selected, although the forward voltage VF can be reduced, there is a limit in further reduction. On the other hand, when the resistivity of the n−-type semiconductor layer is reduced, although the forward voltage VF can be realized, there is a problem that breakdown voltage is deteriorated. In a semiconductor device of the invention, a second n−-type semiconductor layer having a low resistivity is laminated on a first n−-type semiconductor layer capable of securing a specified breakdown voltage. P+-type semiconductor regions are made to have depths equal to or slightly deeper than the second n−-type semiconductor layer. By this, in a Schottky barrier diode in which leak current IR can be suppressed by pinch off of a depletion layer, the forward voltage VF can be reduced and the specified breakdown voltage can be secured.
摘要翻译：其中p型+型半导体层设置在n +型超导外延层中的肖特基势垒二极管可以在不考虑漏电流IR的情况下实现降低正向电压VF。然而，当与正常肖特基势垒二极管相比时，正向电压VF通常较高。当适当地选择肖特基金属层时，尽管可以减小正向电压VF，但是进一步减少是有限制的。另一方面，当降低n +型半导体层的电阻率时，虽然可以实现正向电压VF，但存在击穿电压恶化的问题。在本发明的半导体器件中，具有低电阻率的第二n + O - 型半导体层被层叠在第一n + 击穿电压。使P + + H型半导体区域的深度等于或略深于第二n +型半导体层。由此，在可以通过耗尽层的夹断来抑制漏电流IR的肖特基势垒二极管中，可以减小正向电压VF，并且可以确保规定的击穿电压。

摘要： A capacity computing apparatus for computing the capacity of a chargeable secondary battery by a microcomputer, wherein a resistance is connected to the secondary battery and a drop voltage because of charging and discharging current in the resistance is amplified by an amplifier, whereby the capacity of the secondary battery is computed on the basis of the amplified value. The capacity of the secondary battery is computed with good accuracy even with a small drop of the voltage in the resistance. Moreover, an influence of an offset voltage in the amplifier is removed by applying a constant voltage to the amplifier at all times. The stored value of the microcomputer is periodically updated, thereby avoiding an influence when the amplification degree of the amplifier is changed due to the temperature change.

摘要： A battery charger charges a discharged battery and can be connected directly to an appliance where it serves as an AC adapter. The output of the battery charger automatically reduces to a trickle maintenance charge as the battery approaches a full charge condition. A Zener diode, used for overcurrent protection automatically turns off the charging function in the event of an overcurrent condition. The circuit automatically resets when the overcurrent condition is removed. A hinged section, when opened out, provides mounting for a battery to be charged. When the hinged section is closed, switches are operated, and electrical connections are made to permit affixing the charger, as an AC adapter, to the normal battery retainer of the appliance.
