Abstract: The electrical cooking apparatus has a hot plate (10), under which an electrical cooking unit (1) is arranged, which is provided with openings (5) for receiving the ends of the glass envelope (20) of an electric filament (21). The hot plate (10) is light-scattering at least in a region (11) laterally of the cooking unit (1). Thus, it is avoided that elements under the hote plate (10) outside the cooking unit (1) are visible, while it is nevertheless achieved that it can be observed whether the cooking unit (1) is in operation and what is the power consumed by it.

Abstract: Method of modifying the microenvironment of an enzyme by grafting peptide chains. The length, the composition and the properties of these peptide chains may interact with the surface of the enzyme and may also be activated at their ends so as to attach them to an insoluble support or to make them react in a copolymerisation reaction to form a gel in which the enzyme will be immobilised in a specified microenvironment. An example showing the modifications of the alcohol dehydrogenase, permitting the regeneration of NADH for the synthesis of alanine in an enzyme bioreactor, illustrates the possibilities of the invention.

Abstract: Spectromètre d'absorption atomique dans lequel chaque échantillon est analysé pour tout élément désiré avant de commencer l'échantillon suivant. De nouvelles caractéristiques incluent une commande de réseau de diffraction, un alignement de carrousel à lampe, une source d'atomes pulsée, une compensation de dérive de lampe, et un contrôle de taux d'intensité. Le réseau de diffraction (G) est mû par un bras (A), le bras (A) par un ruban tendu (B) enroulé sur un tambour (D), et le tambour directement par un moteur. Le carrousel à lampe (C) monte sur un levier en forme de ''L'' ayant un bras horizontal et un bras vertical. Le carrousel (C) pivote sur un axe horizontal (P1) à l'extrémité du bras vertical. Le levier pivote lui-même sur un axe horizontal (P2) à l'angle du L; il est entraîné autour de son axe par un moteur (M2) et vissé (W) à l'autre extrémité du L. La rotation du carrousel (C) sur son axe fait prendre position à la lampe de droite et la règle avec précision dans la direction verticale. Le fait de pivoter le levier simultanément sur son axe d'angle positionne la lampe avec précision dans la direction horizontale. Le source d'atomes pulsée est une combinaison d'un brûleur à jet de gaz d'angle et d'une unité de décharge. Pendant les impulsions il produit une haute absorption avec des limites de détectabilités meilleures; la puissance moyenne est inférieure. Le compensateur de dérive de lampe remplit les deux fonctions de pulsation d'absorbeur pour obtenir une lecture d'intensité de lampe entre les impulsions. Le contrôle de taux d'intensité est obtenu en exploitant encore plus au-delà la pulsation, c'est-à-dire en prenant des mesures à une temporisation (et à un temps de remise à zéro) connue, après chaque impulsion.

Abstract: Un système de traitement de signaux vidéo comprend une mémoire pour contenir des données numériques, un réseau de circuits de canaux d'entrée et de sortie pour lire les données de la mémoire et écrire des données dans la mémoire ainsi que des circuits de traitement pour traiter les données lues de la mémoire et produire des données à écrire dans la mémoire. Chacun des canaux d'entrée et de sortie produit deux types de signaux de demande de mémoire, un signal de demande normale et un signal de demande urgente. Le signal de demande normale est produit pour avoir accès aux données de la mémoire pour des opérations normales de lecture et d'écriture. Le signal de demande urgente est produit pour accéder à la mémoire lorsque le réseau de circuits de traitement se trouve dans un état de pose, en attente, soit pour obtenir des donnés du canal d'entrée soit pour fournir des données au canal de sortie. Les signaux de demande normale de lecture et d'écriture sont manipulés avec une priorité sensiblement identique par un premier circuit d'ordonnancement. Les signaux de demande urgente sont manipulées par des seconds circuits d'ordonnancement selon une planification de priorité fixe. L'utilisation du second circuit d'ordonnancement invalide le premier circuit d'ordonnancement.

Abstract: An atomic planar-doped field-effect transistor is disclosed, which is featured by a channel region (12) of a limited thickness between source (16) and drain (18) with at least one atomic planar-doped layer (13) formed therein and a barrier layer or layers (14,15) provided on the upper or lower side or on the both sides of the channel region (12). The channel region (12) is formed of a semiconductor of a low impurity concentration or of an n-type with the atomic planar-­doped layer (13) having high concentration donor impurities or of a p-type with the atomic planar-doped layer (13) having high concentration acceptor impurities. The upper barrier layer (15) is provided between the channel region (12) and a gate electrode (17) and the lower barrier layer (14), if present, is provided between the channel region (12) and a substrate (11). They are formed of a semiconductor of a low impurity concentration which is different from the semiconductor of the channel region (12) and makes a heterojunction with the channel region (12) and which has a smaller electron affinity than the semiconductor of the channel region (12) having the donor planar-doped layer (13) or a larger value of a sum of electron affinity and energy gap than the semiconductor of the channel region (12) having the acceptor planar-doped layer (13). With the upper barrier layer (15), the transistor of the present invention has a large gate-­forward turn-on voltage. The short channel effects are suppressed by adding the lower barrier layer (14) to the transistor.

Abstract: In an induction heating apparatus which comprises a high frequency power source for inducing eddy currents into a plated steel sheet, electronical means are provided in order to vary the frequency of the power source. The variation of the frequency is obtained by providing a phase angle signal of the voltage phase at the output of the high frequency inverter, which phase angle signal is used to create a phase delay. The delay or advance of the voltage phase creates a variation of the frequency which is beneficial in conditions where a constant frequency would produce standing wave irregularities of the interface area between the steel sheet and the plated layer which is heated and vibrated by the induced currents and magnetic fields.

Abstract: In the machine of this invention, a rotation-support member is provided in an outer tub (15) for containing water so that the rotation-support member (26) can rotate about a vertical axis (YY). The rotation-support member supports a perforated inner tub (41) rotatable about a horizontal axis (XX). A heating means (141) heats air in the inner tub. When the laundry is washed or rinsed, the laundry is loaded in the inner tub (41), water is supplied to the outer tub (15) until the water reaches inside the inner tub, and the inner tub is rotated about the horizontal axis (XX). The laundry is prevented from jumping out of the inner tub (41) during the washing and rinsing process due to boards (45) or net (44) provided in the inner tub. When the washed or rinsed laundry is dehydrated, water is drained from the outer tub, the rotation-support member (26) and the inner tub (41) are rotated together about the vertical axis (YY) in the same direction at the same high speed. When the dehydrated laundry is dried, the inner tub (41) is rotated about the horizontal axis (XX), heated air is supplied to the inner tub (41), and the laundry is uniformly exposed to the air to dry. The humid air used for drying the laundry is dehumidified, moisture in the air is drained to the outside, and dehumidified air is recirculated in the machine. The machine of this invention shifts from one process to another without changing its attitude. Consequently, the machine is simply constructed and inexpensively manufactured.
