Abstract: Novel external medications comprise, as essential components, the following three components (A) to (C):
     (A) an α-monoglyceryl ether represented by the following formula (I):
     wherein R means an alkyl or alkenyl group having 10- 24 carbon atoms;   (B) a physiologically active material; and   (C) an oily material.   
     The external medications have extremely high skin occlusive properties and significantly-improved absorptivity of phosiologically active materials. Therefore, a smaller amount of the medications compared with the conventional ones can give sufficient pharmacological effects and thus side effects can be reduced. 
     The external medications can be applied to many drugs, agricultural chemicals, growth hormones and the like, which are expected to show pharmacological effects upon their percutaneous absorption.

Abstract: Disclosed are a method and apparatus for rapidly heating a thermionic vacuum tube cathode, thereby enabling the vacuum tube to be placed in useful operation shortly after the tube is switched on. Rapid heating of the cathode is achieved by passing current through the cathode, thereby directly heating it. Simultaneously, the cathode is also heated by an indirect radiant heater and by electron bombardment by electrons emitted from the heater. When the cathode reaches its operating temperature, the direct heating current and the electron bombardment are stopped and the cathode is maintained at its operating temperature by the indirect heater alone. Cathode warm-up times of less than 1 second may be attained using this invention.

Abstract: Die Schwungradelemente (1,2) sind elastisch mittels zweier parallelgeschalteter Federgruppen (25,26) gekoppelt, wobei die eine Federgruppe (26) mit Spiel arbeitet und im wesentlichen erst wirksam wird, wenn größere Drehmomente übertragen werden. Dementsprechend hat das Schwungrad bei niedriger Drehzahl, wenn motorseitig nur geringe Drehmomente erzeugt werden können, eine sehr niedrige, allein durch die spielfreie Federung (25) bestimmte Resonanzfrequenz, welche noch unter den Frequenzen der in dieser Betriebsphase auftretenden Schwingungen liegt. Bei Übertragung größerer Drehmomente, welche motorseitig nur bei höheren Drehzahlen erzeugt werden können, steigt zwar die Resonanzfrequenz aufgrund der Wirkung der spielbehafteten Federgruppe (26) an, jedoch bleibt die Resonanzfrequenz unterhalb der bei höherer Drehzahl erhöhten Frequenz der auftretenden Schwingungen.
