Abstract: To provide a mechanism for performing environment control in a plant cultivation device and process control regarding to a work process for cultivating a plant. A plant cultivation device includes a plurality of sensors for monitoring a growing condition of a plant to be cultivated; an environment controlling unit for controlling an environment which is a condition of at least one of light, air, water, and space in the plant cultivation device; and a process controlling unit for controlling a work process for cultivating the plant.

Abstract: Provided is a plant cultivation device wherein the occurrence of tipburn is suppressed. This artificial light-type plant cultivation device 1 is provided with a cultivation chamber 4, the inside of which can be sealed. Within the cultivation chamber 4, the plant cultivation device is provided with: a cultivation room 10 for growing a plant; and an air circulation system 30 for generating an air flow from top to bottom in the cultivation room 10. Since the air circulation system 30 can blow air to a plant V from directly above, air is blown to new leaves growing in a central portion of the plant to promote transpiration. As a result, sufficient calcium can be supplied to the growing leaves and tipburn is less likely to occur.

Abstract: The purpose of the present invention is to reduce location-related and time-related changes in a cultivation environment in a plant factory. This cultivation device 1A is used in an artificial light plant factory, and is provided with: a closed cultivation room 10A; a plurality of cultivation chambers 20A defined by dividing the cultivation room 10A in the vertical direction; an air circulation device 30 which supplies air adjusted to a predetermined condition to each of the plurality of cultivation chambers 20A at a predetermined flow rate and collects the supplied air from the plurality of cultivation chambers 20A to circulate the air; and a nutrient solution circulation device 40 which supplies a nutrient solution adjusted to a predetermined condition to each of the plurality of cultivation chambers 20A at a predetermined flow rate and collects the supplied nutrient solution from the plurality of cultivation chambers 20A to circulate the nutrient solution.

Abstract: A vehicle drive apparatus for supplying oil pressure to a hydraulic servo at restart of an engine. The vehicle drive apparatus includes an accumulator that accumulates the oil pressure, an electromagnetic switching valve that retains oil pressure of the accumulator when an oil pump is stopped, a switching valve control unit that controls opening and closing of the electromagnetic switching valve, and a restart determining unit that determines whether or not to restart the vehicle drive source from a stopped state. When it is determined by the restart determining unit to restart the vehicle drive source, the switching valve control unit is started so as to supply the oil pressure accumulated in the accumulator to the hydraulic servo. As a result, engine friction engagement elements are quickly engaged to enable starting of a vehicle.

Abstract: The connector includes a connector housing having two terminal fittings and terminal receiving chambers for receiving the terminal fittings, and a spacer 4 to be inserted into the connector housing through an opening. A receptacle for inserting an unlocking jig is formed on the spacer. The receptacle is opened at an outer wall of the spacer and a boundary wall to the connector housing 3. The receptacle is disposed in a manner not to spread across two terminal-receiving chambers. The receptacle communicates with one of the terminal-receiving chambers. A block of a main body of the spacer blocks a path between the receptacle and the other terminal-receiving chamber.

Abstract: A manufacturing method for a resin product comprised of a plurality of separate pieces and having a flange, the plurality of separate pieces including one as a separate piece having a flange corresponding to the flange of the resin product, comprises primary-injection-molding the plurality of separate pieces including the separate piece having the flange by a primary injection of a resin, and having respective separate planes of the plurality of separate pieces in abutment, joining the separate pieces together to mold the resin product having the flange by a secondary injection of a welding resin. When molding the plurality of separate pieces including the separate piece having the flange by the primary injection of the resin, a gate part for molding the flange of the separate piece having the flange is positioned inside the flange.

Abstract: In a position detecting switch, a first movable contact is disposed in a first receptacle formed in a sliding body and is urged toward a casing member by a first spring so as to engage first and second stationary contacts mounted in the casing member when the sliding body is in a selected position. In order to prevent non-contact due to rotating moment of the first movable contact relative to the stationary contacts one or more features for inhibiting or reducing the relative moment are provided such as: (1) The first and second stationary contacts can be urged toward the first movable contact by fourth and fifth springs. (2) An elastic member or members can be disposed in a clearance between end walls of the sliding body and walls of the first receptacle. (3) The first spring can be restrained to apply its load to a substantially middle portion of the movable contact. (4) A plurality of the first springs can be provided to apply load the movable contact at a plurality of locations in a lengthwise direction.

Abstract: An electromagnetic valve includes a hydraulic circuit coupling having an input port and a strainer mounted over the input port. The strainer is an entirely planar member and includes a filter portion having a plurality of pores forming a mesh and a retaining portion formed around the outer circumference of the filter portion. The strainer is fixed on the cylindrical wall of the input port of the hydraulic circuit coupling. The hydraulic circuit coupling may have a plurality of projections for engaging and holding the strainer. Alternatively, the retaining portion of the strainer may have a plurality of coplanar projections extending from its outer circumference coplanar with the filter portion and mating with a groove formed around the inner circumference of the input port of the coupling.
