摘要:
A method for removing an organic extraction solvent from an extraction residue, which is characterized in that an oil or fat is allowed to contact an extraction residue remaining in an oil-and-fat extractor which contains an organic solvent, and the oil or fat is then drawn out of said extractor. The procedures of allowing oil or fat to contact said residue and of drawing the oil or fat out of said extractor are repeated until the density of the solvent in the atmosphere of said extractor becomes lower than the lowest ignitable limit.

An electrophotographic copying apparatus including by a blank lamp lighting control for lighting only predetermined ones of emitters forming a blank lamp during the operation of image forming apparatus in a check mode. If copying is carried out in the check mode, some stripes are drawn on copied images in parallel with the direction of movement of a photoreceptor by lighting of a predetermined number of the emitters. Further, the aforementioned blank lamp is constructed to light all the emitters simultaneously for a short time, so that stripes are drawn on the copied images perpendicular to the direction of movement of the photoreceptor. Depending on the parallelism of the stripes with the sides of a copying paper, it can be determined whether the distortion in the copied images is caused by the optical system or by the copying paper conveying mechanism.

A Schmitt trigger circuit has a first transistor for inversion having a base supplied with an input voltage. A level shift diode shifts an emitter voltage of the first transistor from a reference level, and a second transistor for switching has a collector and an emitter respectively coupled to an anode and a cathode of the level shift diode. The emitter of the second transistor is coupled to a first power source voltage. A switching part is coupled between a base of the second transistor and a second power source voltage higher than the first power source voltage, for controlling switching of the second transistor. An output circuit is coupled between the first and second power source voltages and supplied with the input voltage through the first transistor for outputting the output voltage. The switching part is controlled responsive to a voltage from the output circuit so as to close when the logic level of this voltage is the high level, thereby turning the second transistor ON.

An ignition device for a plasma jet ignition plug is provided. A resistance for decreasing electric noises is not incorporated in a plasma jet ignition plug. A resistance of not less than 1KΩ and not more than 20KΩ is provided to a path from a spark discharge circuit to a center electrode, thus reducing the generation of electric noises at the time of trigger discharge. Along with the reduction of the generation of electric noises, a loss of energy at the time of plasma discharge can be reduced by setting an inner resistance provided to a line extending to the center electrode from a plasma discharge circuit to 1Ω or less. Accordingly, the plasma jet ignition plug can jet flame-shaped plasma sufficiently large for igniting an air-fuel mixture.
