摘要:
Moranoline, or 2-hydroxymethyl-3,4,5-trihydroxy piperidine, is prepared by directly reducing an actinomycetes culture solution containing nojirimycin, followed by isolation, as for example, through the utilization of an ion exchange resin. The corresponding N-methyl derivative can be obtained through the addition of formaldehyde to the culture solution prior to the reduction.

摘要:
A first circulation channel connects a first heat demand part and first supply heat exchanger with its forward route and return route. Supply and discharge channels are connected to a first heat accumulation tank, which accommodates a second heat medium heated in the first supply heat exchanger and supplied via the supply channel. A heat accumulation switching valve changes over communication of the second heat medium serving as hot heat or cold heat flowing from the first supply heat exchanger and supplied to the first heat demand part without branching to the supply channel or branching to the supply channel and supplied to the first heat accumulation tank. A heat-accumulating hot-water-supplying air conditioner operates at a first temperature when the second heat medium from the first supply heat exchanger branches to the supply channel, and at a second lower temperature when the second heat medium does not branch to the supply channel.

摘要:
A valve control device performs control for eliminating or preventing fixation of an EGR valve (30) by opening/closing the valve near its fully closed position. After an engine stops, the valve control device performs “a fixation avoiding operation” for opening/closing EGR valve (30) near the fully closed position, and further, performs “a fixation determining operation”. When it is determined that the fixation of EGR valve (30) is eliminated, EGR valve (30) is positioned at the fully closed position, and a reference position is corrected such that the fully closed position is regarded as a reference position at which a valve opening/closing control is performed during the operation of the engine.
摘要:
A valve control apparatus of a diesel engine (1) is provided with an EGR valve (30), which is provided in an EGR passage (26) of the engine (1) and varies the flow rate of exhaust gas flowing through a passage (26) by carrying out an opening and closing motion, and an actuator (28), which executes a sticking avoiding operation for dissolving or preventing a sticking of a valve (30) by causing the valve (30) to move to and fro so as to open and close the valve (30) by a predetermined moving amount respectively in one direction and the other direction near a full-close position of the valve (30). The apparatus inhibits the sticking avoiding operation by the actuator (28) when an ignition OFF operation is carried out without starting an operation of the engine (1) after an ignition ON operation is carried out. As a result, it is possible to prevent a useless valve opening and closing motion and achieve power saving.
