Abstract: A carbamate ester compound represented by the general formula: Z—OCONH(CH2)nNHCOO—Z??[I] wherein Z is [i], [ii], or [iii] below, and n is an integer of 2 to 10, (wherein R1 and R2 are each independently a lower alkyl group having 1 to 5 carbon atoms, R3 is a hydrogen atom or a lower alkyl group having 1 to 5 carbon atoms, and a is 1 or 2). The carbamate ester compound is used as a vulcanizing agent for carboxyl group-containing acrylic rubber and improves the delay of the vulcanization rate by scorch suppression.

Abstract: A fuel cell system includes a nozzle for guiding a fuel gas injected from a first injector and a second injector to a diffuser. An injector control portion performs a first injection control mode when a fuel cell stack is in a first load state. When the fuel cell stack is in a second load state, the injector control portion switches between a second injection control mode and a third injection control mode depending on the circumstances.

Abstract: A fuel gas injection device of a fuel cell system includes an ejector having a nozzle that generates a negative pressure by discharging a fuel gas injected respectively from a plurality of injectors so as to draw-in a fuel exhaust gas discharged from a fuel cell stack and mix the fuel exhaust gas with the fuel gas. A total orifice equivalent diameter obtained by adding together orifice equivalent diameters of respective injection holes of the plurality of injectors and an orifice equivalent diameter of an injection hole of the nozzle are set such that SE<ST.

Abstract: A gas-liquid separator includes a casing in which there are formed an inlet port to which a gas-liquid two-phase flow is supplied, and an outlet port through which a gas flow is discharged after the gas-liquid two-phase flow has been separated into a gas and a liquid. A gas-liquid separation chamber is formed in the casing by a partition wall. The inlet port opens on a surface of the partition wall in the gas-liquid separation chamber. The gas-liquid separator further includes a deflection member configured to change a flow direction of the gas-liquid two-phase flow that flows in from the inlet port, and a clearance is formed between the deflection member and an inner wall of the casing.

Abstract: A gas-liquid separator includes a casing in which a first inlet port, a second inlet port, and an outlet port are formed. Inside the casing, a first gas-liquid separation chamber and a second gas-liquid separation chamber are formed by a partition wall. A gas-liquid two-phase flow that flows in from the first inlet port passes through the first gas-liquid separation chamber and is subjected to gas-liquid separation. On the other hand, a gas-liquid two-phase flow that flows in from the second inlet port passes through the second gas-liquid separation chamber and is subjected to gas-liquid separation. The gas flows after having undergone gas-liquid separation are collected together in a collection chamber, and are further discharged from the outlet port.

Abstract: The present invention provides a lithium polymer cell having high ion conductivity and solid strength high enough to be used as a solid electrolyte for electro-chemical element. The present invention relates to a lithium polymer cell sandwiching between a positive electrode and a negative electrode a solid electrolyte formed from a cured film formed of a lithium ion conductive composition comprising one or more curable oligomers, one or more ethylenically unsaturated monomers and electrolytic salts, and a manufacturing method thereof.

Abstract: A controller of a label printer employs an electronic photographic system which makes printing successively on a continuous printing paper on which a multiplicity of label papers are affixed. There are provided a position sensor using a photoelectric transducer element which is disposed to face the continuous printing paper and detect a difference in the transmissivity of light of the continuous printing paper and a label position detector for processing a detection signal of the position sensor to derive a timing control signal corresponding to a position of the label paper. The timing control signal of the label position detector is used to control operation timings for each of the portions for the continuous printing paper.
