Abstract: A pump device according to one embodiment includes a pump and a symbol. The pump includes at least one pump structure and a suction port, wherein a displacement of the at least one pump structure, the displacement being a delivery amount per rotation, changes in accordance with a command current. The symbol is displayed on a surface of the pump, the surface facing in a direction different from a direction in which the suction port is open. The symbol stores actual measurement data or save location information on the actual measurement data, the actual measurement data indicating an actual relationship between the command current and the displacement of the at least one pump structure.

Abstract: Provided is an electric device made more convenient by being configured such that the temperature of a wide area in each accommodation section can be individually adjustable. In an electric device, a first refrigerant pipe is provided to a right-side member constituting a side surface of a first accommodation chamber, and a second refrigerant pipe is provided to a left-side member constituting a side surface of a second accommodation chamber. The first refrigerant pipe and the second refrigerant pipe are independent of each other. A regulating valve includes: a first regulating valve provided to the first refrigerant pipe, and a second regulating valve provided to the second refrigerant pipe.

Abstract: Provided is an electrical device. In a setting unit, a right-room temperature display unit displays a set temperature or the current temperature of a first housing room. A left-room temperature display unit displays a set temperature or the current temperature of a second housing room. A right-room temperature setting button is an operation unit for a user to switch the set temperature of the first housing room. A left-room temperature setting button is an operation unit for a user switch the set temperature of the second housing room. The set temperature difference between the first and second housing rooms is controlled to be within a prescribed value. When the set temperature of one of the first and second housing rooms is changed so that the set temperature exceeds a prescribed value, a microcomputer automatically changes the other set temperature so that the set temperature difference is within a prescribed value.

Abstract: A hydraulic pump performance deterioration detection system according to one embodiment includes: a hydraulic pump that is driven by a prime mover and that supplies a hydraulic liquid to a hydraulic actuator to move the hydraulic actuator; a switching valve located on a passage through which the hydraulic liquid delivered from the hydraulic pump flows, the switching valve being switchable between an open position and a closed position; and control circuitry configured to change a rotation speed of the prime mover. When the hydraulic actuator is not moving, in a state where the switching valve is switched to the closed position, the control circuitry determines whether or not performance of the hydraulic pump has deteriorated based on the rotation speed of the prime mover and a delivery pressure of the hydraulic pump measured by a pressure sensor.

Abstract: A hydraulic pump performance deterioration detection system according to one embodiment includes: a variable displacement hydraulic pump that supplies a hydraulic liquid to a hydraulic actuator to move the hydraulic actuator; a regulator that changes a displacement of the hydraulic pump in accordance with a command current; and control circuitry that feeds the command current to the regulator. When the hydraulic actuator is not moving, in a state where a switching valve located on a passage through which the hydraulic liquid delivered from the hydraulic pump flows is switched to a closed position and the hydraulic pump is being driven at a predetermined rotation speed, the control circuitry determines whether or not performance of the hydraulic pump has deteriorated based on a current value of the command current and a delivery pressure of the hydraulic pump measured by a pressure sensor.

Abstract: The object is to obtain a foam, an interior material, and a molded article destined for an interior automotive or other vehicular material which can inhibit the formation of crystals in the fogging test. The present invention is a foam, an interior material and a molded article destined for an interior vehicular material, comprising a fogging inhibitor, to keep the amount of the precipitate detected by the fogging test at 0.8 mg or less. The foam and the interior material obtained according to the present invention can be suitably used as a dash board in front of the driver's seat, an interior material at the door and as an interior material of the ceiling in an automobile.

Abstract: A polyolefinic resin is combined with a (meth)acrylic polyfunctional monomer compound having an aromatic ring, an alicyclic ring or a heterocyclic ring nearly in the center of its chemical formula, and a pyrolyzable chemical foaming agent to give a curable and foamable polyolefinic resin composition. The composition is shaped into a sheet, then cured and foamed into a sheet foam. The cured foam of polyolefinic resin has a curing degree of from 10 to 70%, and has the advantages of good heat resistance, good workability and shapability, and good pressure resistance.
