Encapsulating material for solar cells which facilitates fabricating solar cell modules and has excellent transparency, heat resistance, flexibility, etc., and a solar cell modules. More specifically, the present invention provides encapsulating material for solar cells comprising a non-crystalline or low-crystalline a-olefin-based copolymer or its composition (I). In a preferred embodiment, the aforementioned copolymer or its composition (I) is a resin composition (C) containing 50 to 100 parts by weight of non-crystalline α-olefin polymer (A) meeting the following requirements: (a) the α-olefin having 3 to 20 carbon atoms is not less than 20 mol %, (b) practically no melt peak as measured by a differential scanning calorimeter is observed, and (c) the Mw/Mn is not more than 5, and 50 to 0 parts by weight of crystalline α-olefin polymer (B) (the total of (A) and (B) being 100 parts by weight).
摘要:
An engine system includes: an exhaust path through which an exhaust gas of an engine passes; an urea injection valve that injects urea into the exhaust path; a catalyst that is provided in the exhaust path on a downstream of the urea injection valve, and that selectively reduces NOx by using ammonia acting as a reducing agent, the ammonia being generated by hydrolyzing injected urea from the urea injection valve; a heating portion that is capable of heating the catalyst and the injected urea; and a control unit that performs first control, in which the urea injection valve injects urea, the heating portion heats the injected urea to generate ammonia, or second control, in which the heating portion increases a temperature of the catalyst to a temperature at which NOx can be reduced, on a basis of an amount of ammonia adsorbed on the catalyst.

There is disclosed a valve assembly for a gas container capable of appropriately discharging a gas from the gas container, even if a valve of a discharge passage has a failure or the like. The valve assembly for the gas container disposed at the gas container has, as passages which allow the inside of the gas container to communicate with the outside, a filling passage which fills the gas container with the gas and a discharge passage which discharges the gas. Furthermore, the valve assembly has a filling-side valve disposed at the filling passage and configured to close this passage, a discharge-side valve disposed at the discharge passage and configured to close this passage, a communication path which connects a downstream side of the discharge-side valve to a downstream side of the filling-side valve, and a shut-off valve disposed at the communication path. When the discharge-side valve does not open due to the failure or the like, the shut-off valve is opened to allow the gas to flow through the filling passage, the communication path and the discharge passage in this order.
摘要:
A hybrid system control apparatus is provided in which an intercooler is disposed upstream of the motor cooling radiator in a flow path of the ambient air flowing in an engine compartment, and/or is disposed such that at least a portion of the intercooler and a portion of the motor cooling radiator contact each other. The hybrid system control apparatus includes a warm-up portion that increases temperature of the boost air by controlling a load of the engine in cold start of a hybrid system such that the boost pressure from the forced air induction device is equal to or higher than a target boost pressure.
摘要:
Upon detecting an external signal which instructs to stop discharge, an input voltage equal to or less than a set value for the prevention of overdischarge, or an output voltage equal to or more than a set value for the prevention of output of an overvoltage, a control unit (12) stops discharge to a load (40) by opening a switching element (4b) of a step-down unit (11b). Upon detecting that an external signal is reset or an input voltage equal to or more than a set value larger than the set value for the prevention of overdischarge, the control unit (12) resumes discharge to the load (40) by setting the switching element (4b) in a switching operation state or short-circuiting it.

摘要:
A pressure reducer includes a piston slidably accommodated in a cylinder to define a decompression chamber and a pressure adjusting chamber. A seal member includes an elastic member and a sliding portion. The sliding portion is pressed by the elastic member such that the sliding portion slides on an inner circumferential surface of the cylinder. An annular member is located on an outer circumferential surface of the piston and between the seal member and the pressure adjusting surface. The annular member is pressed against the inner circumferential surface of the cylinder with a force that is less than a force with which the sliding portion is pressed against the inner circumferential surface of the cylinder. Thus, the pressure reducer prevents the piston from being moved by an excessive amount with highly accurately adjusting pressure.

Disclosed is a seal structure of a high-pressure tank capable of properly securing seal efficiency. The seal structure of the high-pressure tank includes a plurality of seal members that have mutually different seal properties and that are installed between a ferrule of the high-pressure tank and a valve body attached to the ferrule. One of the plurality of seal members has low temperature resistance, and the other has high temperature resistance. A first seal member is an O-ring formed of butyl rubber or silicone. A second seal member is an O-ring formed of EPDM. Furthermore, the two O-rings are different in gas permeability from each other. This seal structure can be applied between the ferrule and the valve body, in addition, between the ferrule and a liner, between the ferrule and a shell, and between the valve body and the shell.
