摘要:
A Rankine cycle system includes: a superheater, an expander including a first outlet discharging steam and a second outlet discharging liquid refrigerant produced therein; a first discharge path discharging the steam from the expander; a condenser condensing the steam introduced through the first discharge path into liquid refrigerant, a condensed water tank reserving the liquid refrigerant produced in the condenser; and a second discharge path discharging the liquid refrigerant from the expander to the condensed water tank, wherein a liquid level in the condensed water tank satisfies a following relation: Δh>ΔPto/ρg, when Δh means a height difference between the liquid level and a lowest liquid level in the second discharge path, ΔPto means a pressure loss when the steam flows into the condenser from the expander through the first discharge path, ρ means a density of the liquid refrigerant, and g means a gravitational acceleration.

摘要:
A novel artificial nucleic acid base pair which is obtained by forming a selective base pair by introducing a group having steric hindrance (preferably a group having steric hindrance and static repulsion and a stacking effect) and can be recognized by a polymerase such as DNA polymerase; a novel artificial gene; and a method of designing nucleic acid bases so as to form a selective base pair with the use of steric hindrance, static repulsion and stacking effect at the base moiety of the nucleic acid. An artificial nucleic acid comprising these bases; a process for producing the same; a codon containing the same; a nucleic acid molecule containing the same; a process for producing a non-natural gene by using the same; a process for producing a novel protein by using the above nucleic acid molecule or non-natural gene, and the like.
摘要:
When there is an extremely low ambient temperature, an electronic control unit controls operation of a circulation path for coolant water in such a manner that, after starting of an engine, the coolant water is supplied from the engine first to a throttle valve and an EGR valve and then to an oil warmer for a transmission. This solves a failure problem in the throttle valve and the EGR valve caused by frost formation at an early stage. As a result, desired operating performance of the vehicle is quickly ensured and heat management in the vehicle is carried out in a desired manner when there is an extremely low ambient temperature.
