Abstract: A display, comprising: a planar display section; a pixel space provided next to a side adjacent to one surface of the display section and encapsulating a plurality of kinds of colorants, each kind having a different color; an accumulation section provided in the pixel space and accumulating the colorants; a separation system that separates a specific kind of colorant from the accumulated colorants in the accumulation section; a transfer system that selects at least one kind of colorant from the separated colorants and transfers this colorant to the side adjacent to the display section of the pixel space. The separation system performs separation utilizing the magnitude of a dielectrophoretic force generated in each colorant upon receipt of an alternating electric field of a specific frequency applied by this system, the magnitude varying depending on the kind of the colorant. A color of at least the one kind of colorant transferred by the transfer system is displayed at the display section.

Abstract: A carrier core for use in an electrostatographic developer composition is a ferrite substantially free of copper and zinc. By being substantially free of copper and zinc, the carrier core is environmentally friendly and eliminates the need for use of conventional copper zinc carrier cores which must be handled as hazardous waste. Developer compositions employing the ferrite carrier core possess suitable properties.

Abstract: When drying of garbage is started, the opening and closing valve 61 is opened, and at the same time the processing tank 21 is heated by the heater 31. Due to the foregoing, temperatures in the processing tank 21 and the heating chamber 30 are raised and water contained in garbage in the processing tank 21 starts evaporating. At a point of time when the heating chamber 30 and the condensing chamber 40 are filled with this steam, the opening and closing valve 61 is closed, and the fan 50 is operated, so that steam in the condensing chamber 40 is cooled and condensed. Therefore, steam generated in the heating chamber 30 flows into the condensing chamber 40, and pressure in the heating chamber 30 becomes negative and the boiling point is lowered. Accordingly, it is possible to evaporate water at a low temperature.

Abstract: A first clamping portion for clamping a stem of a dial gauge and a second clamping portion for clamping a pole of a stand are provided in a bracket body. The clamping portions are respectively composed of supporting holes; clamping screws which are screwed in a direction perpendicular to the axes of the supporting holes; and clamping tops pressed toward the inside of the supporting holes by the movement of the clamping screws in the axis direction with screwing the clamping screws.

Abstract: An article 1 to be prevented from forgery previously contains an optical semiconductor, the mixing ratio of which is predetermined. Under the condition that a light source 6 is turned off, microwaves are emitted to the article 1 to be prevented from forgery through a feed phone 5. These microwaves are reflected on the article 1 to be prevented from forgery and supplied to a receiving section 8 through a feed phone 7, so that the receiving level of the microwaves can be measured. Next, the light source 6 is turned on, and the receiving level of the microwaves is measured in the same manner. When an optical semiconductor is irradiated with rays of light, it is excited, so that the microwave reflection factor is enhanced. Accordingly, the receiving level in the case where the light source 6 is turned on is higher than the receiving level in the case where the light source 6 is turned off.
