摘要:
An electron beam irradiation system has a pumping block at an end of a microscope column of electron optics. The system has the rotary stage, the microscope column for directing an electron beam at the target on the rotary stage, the pumping block for evacuating air in the gap between the column and the target, a moving mechanism for sliding the rotary stage between a working position and a mounting position, and a cover member. In the working position, the target is opposite to the column. The cover member is brought into intimate contact with the rotary stage or target to prevent vacuum deterioration when the rotary stage moves from the working position to the mounting position.

An electron beam irradiation apparatus, includes a support section for supporting an electron beam irradiation subject to be irradiated with an electron beam, and an electron beam irradiation head opposed to the electron beam irradiation subject via a minute space, the electron beam irradiation head having an electron beam emission hole for irradiating the electron beam irradiation subject with the electron beam. In the electron beam irradiation head, an electron beam path communicating with the electron beam emission hole is provided, and in addition one or more ring shaped gas suction grooves opened from a surface of the electron beam irradiation head facing the electron beam irradiation subject is formed around the electron beam emission hole. Vacuum pumps are coupled to the electron beam path and the ring shaped gas suction grooves, and the electron beam path is held in a high vacuum state.

A bioassay substrate (1) is flat and has a disc-shaped main side like an optical disc such as CD. The substrate (1) is rotatable about a central hole (2) formed therein. The substrate (1) has formed on the surface (1a) thereof a plurality of wells (8) where a probe-use DNA (detection-use nucleotide chain) and sample-use DNA (target nucleotide chain) react with each other for hybridization. The substrate (1) has a transparent electrode layer (4) formed as an underlying layer of the well (8). For hybridization, an external electrode (18) is placed in a position near the transparent electrode layer (4) from above the top surface (1a) of the substrate (1) to apply an AC power to between the transparent electrode layer (4) and external electrode (18) in order to apply an AC electric field perpendicularly to the substrate (1).

One field is formed of a plurality of sub-fields, and each one of the sub-fields includes an initializing period, addressing period, and sustained period. The sub-field is one of an entire-cell initialization sub-field or a selective-cell initialization sub-field. When the entire initialization sub-field is switched to the selective one or vice versa, an initializing voltage which generates initializing discharge in the entire initialization sub-field is controlled. This control allows varying the number of the entire initializations and stabilizing address discharge in a plasma display panel, and at the same time, making the black luminance inconspicuous for improving the picture quality.

Bioassay equipment which prevents a variation in concentration of a medium or deposition/bonding of a substance in the medium to be caused by drying of the medium being stored or held in a reaction region providing an inter-substance interaction field. The bioassay equipment (2) comprises at least a means for supplying a medium containing a substance pertaining to the interaction to the reaction region R providing the field of inter-substance interaction such as hybridization, and a means for supplying required water automatically. The bioassay equipment (2) may comprises a means for automatically detecting the volume of the medium held in the reaction region R.

One field period includes at least one subfield (SF) group made of at least two successive SFs. In the SF group, in the SF subsequent to a SF in which no sustaining discharge is caused, writing discharge is controlled to cause no sustaining discharge. One of all-cell initializing operation and selective initializing operation to be performed in the initializing period in the top SF of the SF group is determined depending on a signal of an image to be displayed. In the top SF of the SF group, the period allocated to the writing discharge in the case of the selective initializing operation is set longer than the period allocated to the writing discharge in the case of the all-cell initializing operation. This structure provides a plasma display panel and a driving method thereof capable of inhibiting increases in black picture level and displaying images at excellent quality.

An information recording and/or reproducing apparatus includes a laser light source from which a laser beam having a wavelength of from 220 nm to 280 nm exits; and a converging lens unit disposed at a nearfield area of a recording medium and upon which the laser beam from the laser light source is incident. The converging lens unit includes an objective lens and a solid immersion lens. The solid immersion lens is disposed between the objective lens and the recording medium, and is formed of a highly refractive material having a high transmittance. The information recording and/or reproducing apparatus records an information signal onto or reproduces an information signal from the recording medium by irradiating the recording medium with the laser beam from the laser light source.

One object of the present invention is to provide means for readily attaining a large scale cultivation of sphagnum moss under various conditions, in other words, means for establishing a sphagnum field under various conditions. Specifically, the present inventors have found that the above object can be attained through provision of a sphagnum cultivation base having a shape-imparted, aggregated mass of dried sphagnum and one or more units of live sphagnum whose stem portions have been aligned in bunch(es), such that the bunch(es) of live sphagnum stem is/are in contact with the aggregated mass of dried sphagnum, that the growth point of of live sphagnum is substantially exposed from the aggregated mass of dried sphagnum, and that the aggregated mass of dried sphagnum is capable of being brought into contact with water of a water basin, and through construction of a system on the basis of the base. The present invention can considerably contribute to environmental improvements, since, in particular, the present invention can grow sphagnum having a remarkable carbon dioxide fixation capacity.
