When starting a fuel cell, valves are operated such that a heat exchange medium flows from a circulation pump through a heating-time bypass duct to a heater and the fuel cell, and the heat exchange medium is heated by the heater. Consequently, the fuel cell can be heated up efficiently and rapidly. When a heating device is driven during operation of the fuel cell, the valves are operated such that the heat exchange medium flows from the circulation pump to the fuel cell, the heater and the heat exchanger in this order. If the amount of heat required for the heating device cannot obtained from the heat generated by the fuel cell, the heater heats the heat exchange medium so as to remedy a deficiency in heat. As a result, the heating device can be made to function adequately. That is, the fuel cell is heated up rapidly when it is started. While the fuel cell is in operation, its temperature is confined to a suitable operational temperature range, whereby the heat generated by the fuel cell can be utilized effectively.

The fuel supply system has a diesel filter with a filtering device accommodated in a housing, and a displacement registering sensor (40) installed on the outflow side of the filtering device. A registering pressure of the sensor is set to a predetermined range which is higher than an initial pressure level which is measured if the diesel filter is in a new state, and lower than a displacement pressure level which is measured if no fuel is being supplied following displacement of the filtering device.

An oil feed controller of an inverter compressor controls the quantity of feeding oil to prevent excess oil from being fed to a compression part when rotational speed of a rotation shaft is increased. The oil feed controller includes an installation hole formed in the rotation shaft to communicate with an oil passage of the rotation shaft, a bypass formed in the rotation shaft to communicate with the leading end of the installation hole, and an oil feeding controlling part installed in the installation hole to close the bypass when the rotation shaft rotates at low speed and to open the bypass when the rotation shaft rotates at high speed such that the quantity of oil ascending to the compression part through the oil passage is controlled.

Disclosed is a washer, more particularly a dryer. The dryer includes a cabinet, a drum in which a drying object is held, a steam generation device to supply steam to the drum, a water supply device to supply water to the steam generation device in order to generate steam, an additive holding part in which an additive is held, and an additive supply device to supply the additive held in the additive holding part to the drum.

An intermediate storage vessel (26) has a cylinder container (26a), a piston (28) provided in the cylinder container (26a) so as to be slidable in a reciprocating manner, and an inpour hole portion (32) and a discharge hole portion (34) that are opened in a cylinder chamber (30) where the piston (28) slides. The inpour hole portion (32) is provided above the discharge hole portion (34). An insulation cover (70) is provided so as to cover the intermediate storage vessel (26) and an insulation mechanism (20), and the cover is removable from the insulation mechanism (20) side.

An intermediate transfer chamber is provided to suppress adiabatic expansion of inner gas on a substrate by controlling exhaust conductance on at least a support part of a substrate and a main surface opposite to the support part. An exhaust apparatus exhausts the inside of an intermediate transfer chamber to reduce the inner pressure of the intermediate transfer chamber from a first pressure to a second pressure. In the exhaust process of the exhaust apparatus, a conductance control apparatus controls exhaust conductance on at least a support part for supporting a substrate and a main surface opposite to the support part. The conductance control apparatus is made of a plate-type member(90) confronting the main surface of the substrate.

The invention relates to a continuous cultivation apparatus for green forages, more specifically to a quick continuous cultivation apparatus for green forages used for feed stripper. A seedbed rotates around a guide rod through a revolving unit. The seedbed is immersed in a water supplying unit in the rotating process, thus water can be supplied periodically. The green forage continuous cultivation apparatus in the invention can be supplied with water in the rotation process. And the water supply period of water can be adjusted through adjusting the speed of rotation process. And the water is not supplied to leaves but to roots, so as to prevent phenomenon that the leaves get rotten with water or generate moss or mildew.

A method is proposed for starting a large diesel engine having a crankshaft and at least one cylinder with a combustion chamber for the combustion of a fuel and with a piston for reciprocating movement between a top dead center position and a bottom dead center position for driving the crankshaft, said method comprising injecting compressed starting air consecutively in each cylinder according to a firing sequence when the piston of the respective cylinder is in the region of the top dead center position, determining a control parameter which is indicative for the firing of the fuel in the respective cylinder and cutting off the compressed starting air for the respective cylinder when the control parameter indicates the firing of the fuel in the respective cylinder. In addition, a large diesel engine, especially a large two-stroke diesel engine, is proposed having a control device being designed for performing this method.
