摘要:
Plural thin plate projecting portions are integrally and projectingly provided on an outer peripheral portion of a side plate member of a bobbin. Each of the thin plate projecting portions comprises a circumferential rib, a slit portion and a reinforcement rib. The circumferential rib is provided on an outer peripheral face of the thin plate projecting portion of the bobbin and then a gap is formed between a claw-shaped magnetic pole of a rotor core and the thin plate projecting portion. A varnish material etc. is caused to adhere to and harden in this gap. By filling a root portion of the claw-shape magnetic pole of the rotor core with varnish material, the resonance vibration in the rotor core can be restrained. As a result, an alternating current generator for use in a vehicle having the small magnetic noise can be obtained.

To reduce noise, there is provided an alternator for motor vehicles having a rotor and a stator which is mounted between a pair of brackets. In the alternator a stator core forming the stator is made up of laminations of thin sheets. And at least a part of the thin sheets making up the stator core are split into four divisions or more in the circumferential direction; the thin sheets of each layer being laid with splits thereof arranged alternately in the circumferential direction.

Since a structure of a cooling fan of an alternative current generator for a vehicle is formed with a resin molding product having an insert metal fitting, a freedom degree on said fan design shape configuration and said installation performance of said fan to a core can be compatible. A cooling fan structure having a high shape configuration design freedom degree and having an installation strength similar to that of said fan according to said prior art can be obtained.

A field emission-type electron source has a plurality of electron source elements (10a) formed on the side of one surface (front surface) of an insulative substrate (11) composed of a glass substrate. Each of electron source elements (10a) includes a lower electrode (12), a buffer layer (14) composed of an amorphous silicon layer formed on the lower electrode (12), a polycrystalline silicon layer (3) formed on the buffer layer (14), a strong-field drift layer (6) formed on the polycrystalline silicon layer (3), and a surface electrode (7) formed on the strong-field drift layer (6). The field emission-type electron source can achieved reduced in-plain variation in electron emission characteristics.

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.
