IPC: H05B3/74
Filed: 1988-07-23
Abstract: In an electrical heater, particularly a radiant heater for glass-ceramic cooking plates, a plurality of spirally interlocking heating resistors are provided, one of which heating resistors passes through the centre region continuously such that it forms two interlocking spirals (10, 17), distributed approximately evenly over the complete heating region, which do not, however, lie immediately adjacent to one another, but between whose spiral turns (20, 21) there is provided in each case at least one spiral turn of a further, spirally laid heating resistor. In this way, the length of the first-mentioned heating resistor can be made significantly larger in a simple manner, namely such that this heating resistor has a very high rated power and nevertheless can be laid without problems in the heating region, without any risk of local overheating.

Abstract: Un circuit (10) à impédance variable est utilisé dans un circuit externe. La valeur de l'impédance est sélectionnée par un cicuit externe. L'impédance variable est générée entre des bornes (14, 16) accessibles pour la connexion à des circuits externes. L'impédance générée entre ces bornes est déterminée par un circuit de commande (18) sensible à des signaux électriques couplés au circuit de commande. Un registre interne au circuit de commande enregistre une valeur qui spécifie l'impédance générée entre les deux bornes. La valeur enregistrée est copiée dans une mémoire morte rémanente programmable (22) en réponse à un premier signal électrique prédéterminé. De même, la valeur enregistrée dans la mémoire morte est sélectivement copiée dans le registre interne au circuit de commande en réponse à un deuxième signal électrique prédéterminé. Divers modes de réalisation d'éléments à impédance variable minimisent le nombre de résistances séparées requises pour obtenir une résolution équivalente à celle obtenue au moyen d'un agencement de résistances en série.

Abstract: In the present invention, an additional cavity is disposed separately from a radio frequency acceleration cavity on the orbit of charged particles of an annular accelerator and there are also disposed an external oscillator for exciting a radio frequency electromagnetic field inside the additional cavity and a coupling antenna. A deflection mode which has a field component at the beam duct portion of the additional cavity through which the charged particles pass in the center orbit direction of the charged particles and generates a magnetic field on a center orbit of the charged particles in the direction perpendicular to the center orbit plane is excited in the cavity, using the external oscillator and the coupling antenna. The resonance frequency of the deflection mode is set to integer multiples of that of the fundamental radio frequency mode in the radio frequency acceleration cavity and the phase relation between the radio frequency acceleration cavity and the cavity is set so that when the phase of the radio frequency electric field intensity of the radio frequency acceleration cavity is 0, the radio frequency magnetic field intensity of the cavity rises in the same phase. According to the present invention, the charged particles cause strong syncho-betatron resonance and spread of the charged particles in the transverse direction is reduced. Therefore, even in the case of inc'- dence of low energy, unstability of the beam is checked and beam loss can be mimimized. Therefore, acceleration and build-up of a large current become possible in the annular accelerator.
