摘要:
A capacitor charging apparatus includes a DC/DC converter for stepping up the voltage of a battery and charging the capacitor; a detection circuit that determines whether a primary current of the DC/DC converter reaches a predetermined limit current; a control circuit that controls the DC/DC converter according to a detection signal received from the detection circuit; and a battery-information detection circuit that detects battery information of the battery. The control circuit performs a predetermined calculation using the battery information received from the battery-information detection circuit to determine the predetermined limit current and to vary the primary current of the DC/DC converter so as to control the DC/DC converter each time the capacitor is charged by the DC/DC converter.

This invention relates to a strobe charge apparatus for charging a capacitor using a flyback transformer. This invention provides a strobe charge apparatus which has a switching element that switches when a charge current that flows through a secondary coil becomes equal to or lower than a predetermined value, and starts energization to a first coil immediately after it is detected that the current that flows through the secondary coil disappears.

A field emission-type electron source 10 includes an insulative substrate 11 in the form of a glass substrate having an electroconductive layer 8 formed thereon. A strong electrical field drift layer 6 in the form of an oxidized porous polycrystalline silicon layer is formed over the electroconductive layer 8. This electroconductive layer 8 includes a lower electroconductive film 8a, made of copper and formed on the insulative substrate 11, and an upper electroconductive film 8b made of aluminum and formed over the electroconductive film 8a. The strong electrical field drift layer 6 is formed by forming a polycrystalline silicon layer on the electroconductive layer 8, rendering the polycrystalline silicon layer to be porous and finally oxidizing it. The upper electroconductive film 8b has a property that reacts easily with silicon and, therefore, formation of an amorphous layer which would occur during formation of the polycrystalline silicon layer can be suppressed.
摘要:
In a field emission-type electron source (10), lower electrodes (8) made of an electroconductive layer, a strong field drift layer (6) including drift portions (6a) made of an oxidized or nitrided porous semiconductor, and surface electrodes (7) made of a metal layer are provided on an upper side of a dielectric substrate (11) made of glass. When voltage is applied to cause the surface electrodes (7) to be anodic with respect to the lower electrodes (8), electrons injected from the lower electrodes (8) to the strong field drift layer (6) are led to drift through the strong field drift layer (6) and are emitted outside through the surface electrodes (7). A pn-junction semiconductor layer composed of an n-layer (21) and a p-layer (22) is provided between the lower electrode (8) and the strong field drift layer (6) to prevent a leakage current from flowing to the surface electrode (7) from the lower electrode (8), thereby reducing amount of power consumption.

An electron source (10) is provided with an n-type silicon substrate (1) as a conductive substrate, a drift layer (6) composed of oxidized porous polycrystalline silicon which is formed on the main surface of the silicon substrate (1), and a surface electrode (7) as a conductive thin film formed on the drift layer (6). The process for, forming the surface electrode (7) includes the steps of forming a first layer composed of Cr on the drift layer (6), forming a second layer composed of Au on the first layer, and alloying the two layers. The surface electrode (7) has higher adhesion for the drift layer 6 and/or stability for the lapse of time. In addition, the surface electrode (7) has lower density of states in an energy region near energy of emitted electrons, in comparison with the simple substance of Cr. In the surface electrode (7), scattering of the electrons is less so that electron emitting efficiency is higher.
