Abstract: A lighting device (20) included in a plant cultivation device (10) includes: a light source unit (25) including an LED serving as a light source; and a cooling unit (30) including a cooling section (21) which allows a cooling medium to flow therein, the cooling unit (30) cooling the light source by heat exchange between the cooling medium supplied to the inside of the cooling section (21) and the light source unit (25). A fan (26) provided in the cooling unit (30) starts and stops supply of the cooling medium in accordance with the temperature (T) measured by a light source temperature sensor (27) provided to the light source unit (25). This makes it possible for a lighting device for plant cultivation and a plant cultivation device to reduce formation of condensation during cooling of the light source, while achieving efficient cooling of the light source.

Abstract: An RF tag which comprises a prepreg plate having a first dielectric layer (20a), and prepreg layers (30a, 30b) respectively arranged on the two major surfaces of the first dielectric layer (20a). The first dielectric layer (20a) is composed of a graft copolymer which is obtained by polymerizing 15-40 parts by mass of an aromatic vinyl monomer (b), which contains 70-95% by mass of a monofunctional aromatic vinyl monomer (b1) and 5-30% by mass of a bifunctional aromatic vinyl monomer (b2), onto 60-85 parts by mass of a polymer (a), which is obtained from an ?-olefin monomer or a chain conjugated diene monomer. Each of the prepreg layers (30a, 30b) is composed of a glass fabric base impregnated with an epoxy resin. An antenna circuit (10) and a metal foil layer (40) are respectively bonded to the prepreg layers (30a, 30b) of the prepreg plate by thermal compression bonding.

Abstract: A prepreg having low dielectric constant, low dielectric loss, and high heat cycle resistance. The prepreg includes a sheet-like preform and a resin-impregnated, sheet-like, fiber-reinforced material thermal pressure adhered to the sheet-like preform. The sheet-like preform includes a graft copolymer (a) in which 15 to 40 parts by mass of an aromatic vinyl monomer are grafted to 60 to 85 parts by mass of a random or block copolymer comprising monomer units selected from nonpolar ?-olefin monomers and nonpolar conjugated diene monomers. The resin-impregnated, sheet-like, fiber-reinforced material includes a sheet-like, fiber-reinforced material (b1) and a thermoplastic resin (b2) into which the sheet-like, fiber-reinforced material (b1) is impregnated. The thermoplastic resin (b2) is a random or block copolymer composed of 60 to 90 mass % of a monomer unit, which is selected from nonpolar ?-olefin monomers and nonpolar conjugated diene monomers, and 10 to 40 mass % of an aromatic vinyl monomer unit.

Abstract: An object of the present invention is to obtain, in an accurate and stable manner, an image density at a tone rise point in a low-density region in order to form a stable image.

Abstract: A high density detecting toner pattern is formed on a photosensitive body and a high density correction is effected by comparing a value detected by a reflection sensor with a high density reference value so as to maintain an image density at a specific level. An image density correcting section adopts a result of the preceding high density correction as the high density reference value, and compares the same with a result of a current high density correction. The image density correcting section effects the half-tone density correction only when a difference reaches or exceeds a preset difference reference value by forming a half-tone density detecting toner pattern on the photosensitive body and comparing a value detected by the reflection sensor with a half-tone reference value. Consequently, it has become possible to provide an image forming apparatus which can maintain a density output of an entire image at a specific level for any kind of images including solid, line, and half-tone, etc.

Abstract: A test patch image is formed and the density thereof is detected to maintain the image quality at a constant level. One of the image forming conditions, for example, the developing bias voltage of the developing unit inside the image forming apparatus that serves as a density controller, and is controlled in accordance with the detection result. Here, a humidity sensor for detecting the environmental change, that is, the humidity, is provided inside the apparatus, and the reference value of the toner mixing ratio is changed and corrected while the developing unit is operating when the humidity sensor detects a change in humidity. However, the toner mixing ratio is maintained and neither changed nor corrected when the density of the test patch image remains at the same level, so that the developing bias voltage is not corrected.
