摘要:
An electrostatic relay essentially comprises a fixed electrode with a fixed contact insulated therefrom, a movable electrode plate with a movable contact insulated therefrom, and a fixed pair of oppositely charged electrets. The movable electrode plate is pivotally supported at a pivot in a cantilever fashion or a seesaw fashion, and also to move about the pivot axis relative to the fixed electrode between two rest positions of closing and opening the contacts. A control voltage source is connected across the fixed electrode and the movable electrode plate to generate a potential difference therebetween. The electrets are disposed adjacent the movable electrode plate to generate electrostatic forces attracting and repelling the movable electrode plate, respectively, when the movable electrode plate is charged to a given polarity. That is, the attracting and repelling forces are cooperative to produce a torque for moving the movable electrode plate in one direction from one of the rest positions to the other. The electrostatic relay is useful for precisely and rapidly operating the relay.

A seed layer having a predetermined pattern is formed on a side of one surface of a second substrate, and a ferroelectric layer is formed on the side of the one surface of the second substrate. A lower electrode is formed on the ferroelectric layer, and the lower electrode and a first substrate are bonded via a bonding layer. A laser beam with a predetermined wavelength is irradiated from a side of other surface of the second substrate to transfer a ferroelectric film, which overlaps with the seed layer, of the ferroelectric layer and the seed layer onto the side of said one surface of the first substrate. The laser beam passes through the second substrate, is reflected by the seed layer, and is absorbed by a second portion of the ferroelectric layer. The second portion does not overlap with the seed layer.

A photoconductor for electrophotography includes a conductive substrate and an organic undercoating layer on the conductive substrate. An organic charge generation layer is deposited on the undercoating layer, and an organic charge transport layer is deposited on the charge generation layer. The undercoating layer contains soluble polyamide resin and/or normal-butylated melamine resin as its main components. Alternately, the undercoating layer may contain resin as its main component, into which are dispersed small particles of anatase-type titanium dioxide. The surfaces of the anatase-type titanium dioxide particles may be treated with aminosilane. These undercoating layers produce a laminate-type photoconductor, which exhibits excellent electrophotographic characteristics that are stable during repeated use over long periods of time, and which vary little in a high temperature and high humidity atmosphere, as well as in a low temperature and low humidity atmosphere.
