Abstract:
A fluid flow controlling device having a working member capable of reciprocating in a tubular case. The working member comprises a pressure detecting portion to detect the pressure of a second fluid, which flows into the tubular case through a second inlet, and to move the working member forwards; and a valve element to decrease the opening of the first outlet in relation to the opening of the first inlet, through which the first fluid is led into the tubular case, in correspondence with the displacement of the working member. By the use of the above fluid flow controlling device, it becomes easy to control the quantity of the first fluid led into the tubular case in relation to that of the second fluid, and it becomes possible to sufficiently supplying the first fluid to the tubular case even when the second fluid is exhausted and cannot be supplied any more so long as the first fluid is not exhausted. Further, the above fluid flow controlling device has a simple structure, performs a reliable action, does not break easily, and is very durable.
Abstract:
A system includes a radiator side flow path for supplying a coolant which has cooled a fuel cell stack to a radiator, a bypass flow path for allowing the coolant which has cooled the fuel cell stack to bypass the radiator, a thermostat valve for increasing a flow rate of the coolant flowing through the radiator side flow path in a case where the temperature of the coolant is high as compared to a case where the temperature of the coolant is low, and an electric heater for warming up the coolant. The electric heater is controlled based on an outside atmospheric pressure and on the temperature of the coolant such that the temperature of the coolant flowing into the fuel cell stack is raised in a case where the outside atmospheric pressure is high as compared to a case where the outside atmospheric pressure is low.
Abstract:
In a circuit substrate of an electric water pump, a Hall IC can be mounted on a circuit substrate at an optimum position in a stable and durable state. The electric water pump includes a motor housing, a stator constituted by a stator core covered by a resin insulator and a coil, a circuit substrate, a holder 6 mounted on the circuit substrate, and a Hall IC mounted on the holder. A holder accommodation portion, into which the holder is inserted, is formed in the insulator, the stator is disposed in and fixed to the motor housing, the circuit substrate is appropriately mounted on the motor housing, and the holder 6 is inserted into and supported by the holder accommodation portion.
Abstract:
In an incubator according to the present invention, a single incubator can be used in any state of four types of devices and thus obviates the need for having many types of devices. A canopy is lowered and raised. In addition to that, a left and right treatment door and a foot end treatment door can be located at their highest positions, lowest positions, and intermediate positions. Also, an infrared heater can be lowered and raised independently of the canopy. This makes it possible to switch the incubator among: a state of an open type incubator; a state of a closed type incubator in which the infrared heater is at its highest position such that the infrared heater can heat the canopy and others; a state of a closed type incubator in which the infrared heater is at its lowest position and this incubator is easily conveyable; and a state of a resuscitation treatment device.
Abstract:
An ion exchange filter for a fuel cell system includes a housing with a fluid flow-in port and a cartridge which is disposed inside the housing and in which an ion exchange resin is filled, the fluid flowing in the cartridge through the flow-in port is filtrated therein by the ion exchange resin and the filtrated fluid flows out through the flow-out port. The housing has a casing having an opened upper end and a lid closing the upper end opening, and the fluid flow-in port has an outer peripheral wall of the casing at a portion above a bottom surface of the cartridge disposed inside the housing and the fluid flow-out port is formed to the lid, and a gap is formed between the housing and the cartridge for flowing the fluid flowing inside the housing through the flow-in port towards the bottom portion of the housing.
Abstract:
A fuel cell power plant comprises plural fuel cell stacks (10A–10B) capable of generating power independently, and a warm-up circuit (33) which can independently warm up the fuel cell stacks (10A–10C). A controller (14) estimates a required output power of the power plant within a predetermined time from when the vehicle starts running (S121–S127), and determines the number of fuel cell stacks satisfying the required output power (S106). The controller (14) economizes energy required for warm-up of the fuel cell stacks while providing the required output power by warming up only the determined number of fuel cell stacks before the vehicle starts running.
Abstract:
The rotor of the present invention is capable of improving magnetic characteristics, general versatility and ease of assembly. The rotor comprises: a rotor shaft; a ring-shaped rotor magnet being disposed coaxially with the rotor shaft; and a non-magnetic cover covering an outer circumference of the rotor magnet. The rotor magnet and the cover are integral-molded with molding resin in a state where an outer circumference of the cover is exposed and both end parts and an inner circumference of the rotor magnet are covered with the molding resin.
Abstract:
A fuel pump attachment structure is provided that includes a cylinder head; a cylinder head cover joined to a top surface of the cylinder head; a bracket mounted to the top surface of the cylinder head so as to be located at a position outside the cylinder head cover; and a fuel pump attached to the bracket. The fuel pump is inserted into an opening formed in the cylinder head cover. A sealing member is arranged between an outer surface of the fuel pump and a surface of the cylinder head cover that defines the opening. Alternatively, a pressing portion is formed in a lower portion of the bracket. The pressing portion presses a pressed portion formed on a periphery of the cylinder head cover from above by means of a bolt that is inserted into the pressing portion and fastened to the cylinder head.
Abstract:
In an infant care apparatus according to this invention, heat rays are radiated from a heat radiation opening of a heater to a bed. The direction of the heat radiation opening can be changed from the first state in which the heat radiation opening substantially faces the bed to the second state in which the heat radiation opening does not substantially face the bed. According to the infant care apparatus of this invention, when the heater is not used, there is no possibility that the remaining heat of the heater is transferred to the infant laying on the bed. There is therefore no possibility that the infant will be unnecessarily overheated. There is no need to operate the heater and the like of the infant care apparatus in such a manner that the infant lying on the bed and surrounding people have feelings that rough operation is performed. This will keep the infant and the surrounding people free from adverse effects in terms of mental health.
