A cultivation method for cultivating leaf vegetables includes preparing correspondence information associating light characteristic information indicative of a characteristic of light with which leaf vegetables are irradiated, with quantified quality information having a quantified quality of leaf vegetables; setting the light characteristic information; and irradiating the leaf vegetables with light.

Cultivation method, information processing apparatus, and control apparatus

A light-emitting apparatus of a cultivation system includes a first light source array and a second light source array adjacent to the first light source array. The first light source array includes first light sources and second light sources. The first and second light sources are arranged in a specific pattern in a predetermined direction. The second light source array includes first light sources and second light sources. The first and second light sources of the second light source array are arranged in the specific pattern in the predetermined direction such that an arrangement of colors of the first and second light sources in the second light source array is shifted from an arrangement of colors of the first and second light sources in the first light source array.

Cultivation system

A classifying apparatus including: a rotor with a plurality of annularly disposed blades, which rotates; and a louver with a plurality of blades which are disposed at an outer circumferential portion of the rotor so as to supply from the outer circumferential portion a fluid for dispersing and classifying a powder material, wherein the powder material is supplied to a gap between the rotor and the louver and centrifugally classified into fine powder and coarse powder, and wherein at least one of the following relationships is satisfied: Relationship (1): &#x3b1;&#x2267;50&#xb0; Relationship (2): D/D&#x2267;1.17 where &#x3b1; denotes an angle formed between imaginary lines connecting the center of the rotor with both ends of each blade of the louver, Ddenotes a diameter of the rotor, and Ddenotes an inner diameter of the louver.

Classifying apparatus, classifying method, and method for producing toner

A fluid spray nozzle for spraying fluid, satisfying a formula (r&#x2212;r0)&#x2266;L tan 35&#xb0;, wherein r0 is a radius of a section having a minimum area of the nozzle when cut perpendicular to a spray direction of the fluid; and r is a radius of cross-sections of an upstream side and a downstream side of the spray direction from the section having a minimum area with a distance of L.
