摘要:
A water solvent extraction degreasing method capable of reducing degreasing time without consideration of abrupt decomposition/vaporization and swelling caused by heat. An organic binder is removed from a molded product that is produced by a powder material mixed with the organic binder and this organic binder contains at least one water-soluble organic compound and at least one water-insoluble thermoplastic resin. The degreasing step of this method includes a water solvent extraction step for extracting the water-soluble organic compound from the organic binder contained in the molded product, using water as a solvent.

The reflecting surface of an aspherical reflector assumes, in the main scanning plane, a curve represented by Z(Y)=AY.sup.2 +BY.sup.4 +CY.sup.6 +DY.sup.8 +EY.sup.10 where Z is the coordinate along the optical axis, Y is the coordinate in the direction that is perpendicular to the optical axis and is included in the main scanning plane, and A to E are coefficients satisfying A.times.C>0. The reflecting surface assumes, in any of auxiliary scanning planes arranged in the main scanning direction, a circular arc that establishes a conjugate relationship in geometrical optics between the deflecting face of a deflector and the scanning surface.

A band rejection filter includes at least of two dielectric resonators and an inductor. Each dielectric resonator is composed of a dielectric base formed as a rectangular prism and having a penetrating hole in a central portion, an inner conductive layer arranged on an inner side surface of the dielectric base, an outer conductive layer arranged on an outer side surface of the dielectric base, a connecting conductive layer arranged on one end surface of the dielectric base to connect the outer conductive layer and the inner conductive layer, an outer conductor layer cut-out groove formed on the outer side surface of the dielectric base, and an independent coupling electrode surrounded by the outer conductor layer cut-out groove on the dielectric base. The inductor connects the independent coupling electrode of the dielectric resonators, and the outer conductive layers of the dielectric resonators are connected with each other. The outer conductor layer cut-out groove is surrounded by the outer conductive layer, thus avoiding change in a resonance frequency in the band rejection filter. The outer end surface of the dielectric base is opened and is surrounded by the outer conductive layer thus avoiding change in attenuation characteristics of the band rejection filter.

A selective calling receiver includes a selective calling receiver main body, a chain clip, a detection circuit, and a control circuit. The selective calling receiver main body has a notification unit for performing a notifying operation when a numerical signal is received The chain clip includes a conductive metal chain and has one end connected to the selective calling receiver main body and the other end connected to a clip. The detection circuit is arranged in the selective calling receiver main body and is electrically connected to the chain clip to detect that a user touches a portion of the chain clip. The control circuit is arranged in the selective calling receiver main body and stops the notifying operation of the notification unit when an output is generated by the detection circuit in a notification enable state.
