摘要:
An electron-emitting device has a pair of device electrodes and an electroconductive thin film including an electron emitting region arranged between the electrodes. The device is manufactured via an activation process for increasing the emission current of the device. The activation process includes steps of a) applying a voltage (Vact) to the electroconductive thin film having a gap section under initial conditions, b) detecting the electric performance of the electroconductive thin film and c) modifying, if necessary, the initial conditions as a function of the detected electric performance of the electroconductive thin film.

On a slab-like board formed of a transparent material is closely attached a wedge-shaped transparent cover member provided with a recess in a central inner portion, thereby to form a clearance. The height of the clearance between the recess and the board is configured to decrease continuously or in steps. When an immunological active substance such as a monoclonal antibody is caused to sensitize carrier particles F, and a reagent having the carrier particles F dispersed into a liquid medium mainly composed of the water is mixed with a specimen, the reaction will occur in which the flocculate is formed from plural carrier particles. When this reaction liquid is poured into the clearance through the opening, the reaction liquid penetrates in the direction having a narrower vertical spacing due to surface tension. A single carrier particle unflocculated can move deep within the recess because it is small in diameter, but the flocculate G is trapped on its way and can not move because of its size.

An apparatus is so constructed as to measure a specific substance in a test specimen by the degree of the aggregation of carrier particles in a reaction solution in which the test specimen is mixed with the carrier particles which carry a substance specifically binding to the specific substance. The apparatus includes a substrate having comb-shaped electrodes mounting the reaction solution and amplifier and alternating oscillator for displaying a variable voltage to the comb-shaped electrodes. The test specimen measuring apparatus having the structure accelerates the aggregation of the reaction solution by applying an alternating voltate to the comb-shaped electrodes in a state that the reaction solution is being mounted on the substrate, and detects the spatial spectrum of the comb-shaped electrodes on which the reaction solution is mounted, thus performing the qualitative or quantitative detection of the presence of the substance in the test specimen.

An image recording method and an image recording apparatus using an ink which is substantially non-adhesive but can be imparted with an adhesiveness when subjected to a pH change. In the image recording method, the ink is subjected to a pattern of pH change to be provided with an adhesive pattern, which is then transferred to a recording medium, such as plain paper, directly or by the medium of an intermediate transfer medium to form an ink pattern corresponding to the pH change pattern.

An electron-emitting device comprises a pair of electrodes and an electroconductive film arranged between the electrodes and including an electron-emitting region carrying a graphite film. The graphite film shows, in a Raman spectroscopic analysis using a laser light source with a wavelength of 514.5 nm and a spot diameter of 1 μm, peaks of scattered light, of which 1) a peak (P2) located in the vicinity of 1,580 cm−1 is greater than a peak (P1) located in the vicinity of 1,335 cm−1 or 2) the half-width of a peak (P1) located in the vicinity of 1,335 cm−1 is not greater than 150 cm−1.

An electron-emitting device comprises a pair of oppositely disposed electrodes and an electroconductive film arranged between the electrodes and including a high resistance region. The high resistance region has a deposit containing carbon as a principal ingredient. The electron-emitting device can be used for an electron source of an image-forming apparatus of the flat panel type.
