When a car driver has backwardly pushed a four-way knob, both legs of a push knob slidably move along a guide surface of an internal pusher member, whereby the four-way knob is tilted along with the push knob. When the car driver has backwardly pushed the push knob while the push knob and the four-way knob remain tilted, the push knob linearly, backwardly moves in conjunction with the four-way knob, whereby an internal switch and an external switch are operated. Therefore, the push knob can be illuminated by an internal LED of a switching board by way of a through hole of the internal pusher member.

To provide a fuel cell system which controls pressure of reaction gas based upon a load reduction request of a fuel cell so that moisture inside the fuel cell can be efficiently discharged.The fuel cell system comprises: a fuel cell which receives a supply of anode gas containing hydrogen at an anode and also receives a supply of cathode gas containing oxygen at a cathode, to generate power; a cathode off-gas flow path for flowing cathode off-gas exhausted from the cathode; a pressure regulator for regulating pressure of the cathode, which is arranged in the cathode off-gas flow path; and controlling means for controlling the pressure regulator such that the pressure of the cathode temporarily becomes lower than a prescribed target pressure value in the case of reducing the pressure of the cathode to the target pressure value based upon an output reduction request of the fuel cell. Preferably, pressure at an outlet of the cathode is reduced to the atmospheric pressure during a prescribed time period in a case where an output of the fuel cell changes from a prescribed high output value to a prescribed low output value during a prescribed time period.
摘要:
A continuous production process, which can allow polymerization to proceed at a milder polymerization temperature and a higher polymerization speed as compared with the conventional method while maintaining a high level of living properties and can produce an (meth)acrylic ester (co)polymer having a narrow molecular weight distribution in a high yield with good productivity. The continuous production process for producing an (meth)acrylic ester (co)polymer comprises the step of continuously feeding an organoaluminum compound-containing polymerization initiator solution and an (meth)acrylic ester into a reactor to continuously obtain a living polymer-containing polymer reaction liquid. The {[molar quantity of methacrylic ester or acrylic ester]/([molar quantity of organoaluminum compound]−[molar quantity of polymerization initiator])} fed into the reactor is regulated to be 15 to 80, and the content of the (meth)acrylic ester in the total feed amount of a polymerization initiator solution and an (meth)acrylic ester fed into the reactor is regulated to not more than 5% by mass.
