A non-combustion suction device includes: a mouthpiece having a suction port; a container configured to accommodate an aerosol source; and a heater including: a porous ceramic substrate that permits infiltration of the aerosol source; a glass layer at least in part on the porous ceramic substrate; a pair of electrode patterns; and a resistor pattern on the glass substrate, the resistor pattern connects the pair of electrode patterns to each other; and a power source connected to the pair of electrode patterns. The power source is configured to supply a power flow through the pair of electrode patterns to cause the resistor pattern to generate heat which atomize, into an aerosol, the aerosol source infiltrated in the porous ceramic substrate; and the porous ceramic substrate has a ratio of porosity to tortuosity of 21 or more.

The spray gun is provided with a nozzle section which mixes gas into raw material liquid and also ejects the raw material liquid. The internal space of the nozzle section has an introduction path into which the raw material liquid is introduced, an open portion in which a flow path is enlarged more than the introduction path, thereby ejecting the raw material liquid in a fine particle form, a reduced diameter portion in which a flow path is made narrower than the open portion, thereby re-aggregating the raw material liquid in a fine particle form, and an ejection orifice portion which ejects the raw material liquid to the outside. In the nozzle section, a gas introduction hole which introduces gas into a base-end-side portion of the open portion is formed.

A flash dryer of cut tobacco comprises a drying duct () for connecting a feeding section () of cut tobacco to a tangential separator (). The drying duct () has an upstream-side duct portion () extending straight from the feeding section () at an elevation angle ranging from 30&#xb0; to 60&#xb0; and a downstream-side duct portion () curving upward in a convex shape. A dry gas that flows through the drying duct () may contain superheated steam.

A retinal disease analyzer processes data obtained by processing a color retinal image and measured visual field data provided by a perimeter to detect the condition of the optic disc and defects in the nerve fiber bundles for the clinical analysis of the condition of the optic disc and the defects in the nerve fiber bundles, and combines detected information on a fundus coordinate system taking into consideration the arrangement of the nerve fiber bundles for the comprehensive analysis of the condition and the degree of progress of glaucoma. The detected information is analyzed on the basis of the distribution pattern of the nerve fiber bundles or the corresponding fundus coordinate system to integrate all the data for analysis. The condition and the degree of progress of glaucoma can be determined on the basis of the integrated data.

The present invention relates to an ophthalmological analyzer, and an object of the present invention is to provide an ophthalmological analyzer capable of making information on the shape of an optic nerve conform to the test results of an eyeground or a visual field to be tested by using a look-up table or the like. The ophthalmological analyzer comprises a recording unit for recording at least test data on subjects and information on shapes of optic nerves, a data input unit to be operated by a tester to enter characters and values for coordinates, and a controller which carries out an analytical operation on the basis of the test data on the subject and the information on the shape of an optic nerve, read from the recording unit. The controller is capable of selecting a piece of information to be used among a plurality of pieces of information on the shapes of optic nerves, of changing at least part of information on the shape of an optional optic nerve or of producing information on the shape of a new optic nerve.

A perimeter capable of objectively adding useful testing points without relying on an operator's intuitional judgment, and capable of performing a reliable test of the field of vision without imposing a useless burden on a subject. The perimeter includes a CPU 11 and a display portion 18. The CPU 11 forms data, which include estimated values, on a visual field characteristic distribution by making an interpolation between tested values of a subject's eye which are obtained by exhibiting a plurality of targets. The display portion 18 displays an unreliable distribution WP indicating a domain estimated to be distant from the tested values on the basis of data on the visual field characteristic distribution and data, which include the tested values, on a distribution of an estimated neighborhood of the tested values.

The present invention relates to a perimetric instrument for measuring a range of a visual field of an eye of a man, and more particularly to a perimetric instrument which includes an abnormal visual field pattern analogical inferring section using a multilayer neural network and can analogically infer an abnormal visual field pattern of a measurement object person. Further, the present invention provides a perimetric instrument which can automatically make a determination of an additional target. In particular, according to the present invention, a multilayer neural network including an input layer, hidden layers and an output layer introduces a neural weight ratio which is determined based on responses when the visual field is normal and abnormal, and as a response from a responding section is inputted to the input layer while an output from the output layer is sent out to an analogical inferring section, the analogical inferring section can analogically infer an abnormal visual field pattern of the measurement object person. Accordingly, it is possible to help judgment of an abnormal visual field pattern by a measurer, and since also labor, time and so forth of the measurer are reduced, burdens to the measurer and them easurement object person can be reduced remarkably.
