Abstract: La combinaison en ligne d'un laminoir réversible (moulin Steckel) (19) et de ses fourneaux de cintrage (21, 23) avec un appareillage (27) de refroidissement accéléré réglable, situé directement en aval du laminoir, ainsi que le procédé associé, permettent de laminer successivement et de façon réversible l'acier de façon à obtenir une réduction totale d'au moins 3:1 environ. Une première réduction est effectuée pendant que l'acier est maintenu, dans les fourneaux de cintrage (21, 23), à une température supérieure au point T¿nr? afin de permettre de manière optimale à l'acier de se recristalliser de manière maîtrisée après chaque passage de laminage. Une deuxième réduction est effectuée pendant que la température de l'acier descend du point T¿nr? environ jusqu'au point Ar¿3? environ. La deuxième réduction est de préférence de l'ordre de 2:1, ce qui permet à l'acier d'atteindre l'épaisseur finale des tôles. La masse d'acier (14) traverse ensuite l'appareillage (27) de refroidissement accéléré réglable, qui de préférence applique un flux laminaire de refroidissement sur au moins la surface supérieure de l'acier qui traverse l'appareillage, cela afin de réduire la température de l'acier du point Ar¿3? environ jusqu'à une température inférieure d'au moins 250 ·C à 300 ·C environ, ou davantage, au point Ar¿3?, à une vitesse de refroidissement de 12 ·C à 20 ·C environ, de préférence de 15 ·C environ, par seconde. On obtient ainsi une structure préférée à grains fins, surtout bainitique, qui confère une résistance et une dureté accrues à la masse d'acier finie.

Abstract: Disclosed is an AC/DC type microwave oven. The AC/DC type microwave oven comprises a rotatable inverter which inverts a DC power source to an AC power source by means of a rotational force, a high voltage transformer which receives a common power source or an AC power inverted by the rotatable inverter and outputs a higher voltage and a magnetron which is driven by the high voltage outputted from the high voltage transformer and radiates a microwave, and further comprises a control unit which controls the operation of the rotatable inverter so as to output a stable frequency. The rotatable inverter comprises a motor, a commutator driven by the motor and a plurality of brushes, which are respectively contacted with an outer surface of the commutator. Therefore, the manufacturing cost is lowered, the attrition rate of the current is lowered, the energy lost by heat is decreased, the size of the microwave oven can be smaller, and the output frequency from the rotatable inverter can be controlled to be kept constant and the microwaves are also more stably radiated.

Abstract: As a novel substance is provided such a new, crystalline substance of Cefditoren pivoxil which has a high purity and an enhanced thermal stability on storage. This crystalline Cefditoren pivoxil may be prepared by a process comprising a step of dissolving amorphous substance of Cefditoren pivoxil in an anhydrous, first organic solvent capable of dissolving said amorphous substance well therein, and steps of replacing the first organic solvent component of the resulting solution by an anhydrous alkanol of 1 to 5 carbon atoms as a second organic solvent, in such a manner that the firstly prepared solution of Cefditoren pivoxil in the first organic solvent is mixed with a volume of the alkanol and then is concentrated below 15°C under reduced pressure, and so on. Thereby, the process proceeds so as to produce a solution containing 50 mg/ml to 250 mg/ml of Cefditoren pivoxil dissolved in the alkanol alone.      From the latter solution, crystals of Cefditoren pivoxil are induced to deposit by addition of water at a temperature of 0 - 10°C. The resulting admixture of the concentrated solution of Cefditoren pivoxil in alkanol with added water and the deposited Cefditoren pivoxil is then agitated 10°C or below, to effect a complete crystallization of Cefditoren pivoxil .
