摘要:
A process is disclosed for the production of an alkyl glycoside stable in hue and odor, which comprises the steps of (1) reacting a sugar with alcohol to obtain an alkyl glycoside reaction product containing a higher alcohol, (2) decoloring the alkyl glycoside reaction product with hydrogen peroxide, (3) contacting the decolored alkyl glycoside with a metal/hydrogen complex represented by formula (I)M(BH.sub.4).sub.z (I)wherein M is an alkali metal, Ca, Zn or (CH.sub.3).sub.4 N; andz is 1 when M is an alkali metal or (CH.sub.3).sub.4 N and z is 2 when M is Ca or Zn; to substantially eliminate residual hydrogen peroxide, and then (4) decomposing the remaining metal/hydrogen complex with an acid.
摘要:
In a hybrid vehicle, a target rotational speed and a target torque or a target operation point of an engine are set to a predetermined optimal efficiency rotational speed and a predetermined optimal efficiency torque that enable the engine to be operated efficiently when the engine is operated while a state of charge of the battery is equal to or more than a control-center state of charge after a start of a driving of the vehicle. Then, the engine and motors are controlled so that the engine is operated at the target operation point and a torque equivalent to a torque demand is output to a ring gear shaft or an axle.

A conversion adaptor enables utilization of a standardized charge cable used when a power storage device mounted on an electrically-powered vehicle is charged by a power source provided outside of the vehicle as a universal cable for transmitting electric power to electric loads having different plug shapes that are respectively standardized from one region to another. Conversion adaptor includes a primary side connector unit configured to be connectable to a connector of charge cable, a secondary side connector unit configured so as to have a plug of an electric load, such as a home electric appliance, connected thereto, and a manipulating unit for manipulating a CCID of charge cable so that relays are switched off when connector of charge cable is connected to first connector unit.
