摘要： A method of forming an electrophotographic coating which includes preparing a mixture which comprises finely divided photoconductive material dispersed in an organic resin binder. The resin, which exhibits an acid value of at least 3, or a hydroxyl value of at least 15, is heat-treated for a time and temperature enclosed within the area ABCDEFGH of the temperature-treating diagram shown in the accompanying drawing. Following this treatment, the mixture is dissolved in a volatile solvent for the binder resin, and the dispersion is coated onto a conductive backing to form a substantially uniform layer.

摘要： An interferometer includes a waveguide core, and thin film heaters with widths W1 and W2. The thin film heaters are mounted directly above the waveguide core, and operate as two types of different annealing regions. The annealing, which is carried out by supplying current to the thin film heaters, can alter the quality of the cladding, and change the stress applied on the waveguide core, thereby making it possible to control the polarization dependency. Thus changing the width of the thin film heaters and/or the amount of the supply current thereto enables the permanent control of the effective refractive index (birefringence index) independently in the transverse electric polarization mode and the transverse magnetic polarization mode. This enables the transverse electric polarization mode to be adjusted to a phase difference of &lgr;/2, and the transverse magnetic polarization mode to a phase difference of zero.

摘要： An optical component has first and second planar lightwave circuits. The first and second planar lightwave circuits are aligned and jointed such that the position of an i-th optical waveguide (where i is an integer greater than or equal to 1 and less than or equal to n) of the first planar lightwave circuit and that of an i-th optical waveguide of the second planar lightwave circuit are matched on a joint interface. An angle formed by the i-th optical waveguide of the first planar lightwave circuit and a normal of the interface is configured to vary in accordance with a value of i within a range satisfying the Snell's law.

摘要： The present invention provides an optical functional circuit where a holographic wave propagation medium is applied and a circuit property is excellent such as small transmission loss and crosstalk. The optical functional circuit where a plurality of circuit elements are formed on a substrate includes the wave propagation medium for converting an optical path of a leakage light so that the leakage light that is not emitted from a predetermined output port of the circuit element is not coupled to a different circuit element. This wave propagation medium is constituted by an optical waveguide that is provided with a clad layer formed on the substrate and a core embedded in the clad layer, and a part of the optical waveguide is formed in accordance with a refractive index distribution which is multiple scattered.

The back coating is comprised of a binder having inorganic particles dispersed therein, the inorganic particles including SnO.sub.2 particles having an average size of about 0.01 to about 0.8.mu.. The back coating does not reduce the S/N ratio of the recording medium.
