Patent EP-0043133-A1 (EP)
Inventor: HATTORI SHINICHIRO
IPC: G02B23/08
Filed: 1981-06-29
Abstract: A light source unit for an endoscope is provided with a light-emitting element (46) and a light receiving element (48) which are provided in an eyepiece section of an endoscope (6). The light-emitting element (46) is supplied with current modified by a specific frequency from an oscillating circuit (51) and produces a light-intensity modulated light. An output signal from the light receiving element (48) is supplied to a filter circuit (53) and a signal of the specific frequency component is taken out from the filter circuit to be compared with a reference voltage in a Schmidt circuit (36). When an operator approaches to the light receiving element (48) and enters a range within a predetermined distance from the light receiving element (48), a light intensity of the light which is emitted from the light emitting element (46) toward the operator, reflected from the operator, and is incident on the light receiving element (48), becomes large. As a result, a signal level supplied to the Schmidt circuit (36) exceeds a predetermined value. At this time, a signal for turning on a light source is produced from the Schmidt circuit (36) to energize a relay (44) and to close a contact (42) of the relay. Then, electric power is supplied from a power source (40) to the light source (14) to turn on the light source (14). As a result, an illuminating light is supplied from the light source (14) to a light guide of the endoscope, whereby an area of an objective portion can be observed through an image guide of the endoscope.

Abstract: A two-piece two-chamber self-activating dental amalgam capsule is designed to have mercury in one chamber (7) and metal powder in the other chamber (8). One section (30) of the capsule contains a chamber (15) comprising inner and outer bore portions (14b, 14c) and the other section (31) of the capsule contains the chambers (7) and (8) preferably arranged concentrically and separated by an annular wall (9). With the capsule closed, the free end of the wall (9) fits into the inner bore portion (14b) and seals the mercury in its chamber (7), the metal powder being sealed in a mixing compartment formed by the chambers (8) and (15). In use, the capsule is shaken and the resulting force due to the inertia of the mercury opens a normally-closed valve formed by a thinner and more flexible area of the wall (9). The mercury passes into the mixing compartment and becomes triturated with the metal powder due to the shaking and forms the dental amalgam required.

Abstract: A call progress tone detection circuit for an automated telephone equipment extracts the low frequency envelope (112) of the unknown signal and examines its period. These period measurements are accumulated (118) and then evaluated. If the envelope period is not reasonably constant over a standard measurement interval, then the call progress tone detection circuit (117) can conclude that the unknown signal is voice. However, if the envelope period is regular, then the call progress tone detection circuit (117) according to the preferred embodiment of the present invention will compare the detected envelope period and other timing parameters of the signal to known periods and corresponding parameters for signals used by the various telephone systems in current use. If there is a match between the detected parameters, then the call progress tone detection circuit (117) identifies the call progress tone for further use by the automatic telephone caller.

Abstract: Un système d'énergie éolienne comprend un support (12) et une turbine (24) ayant un arbre monté en rotation sur le support. La turbine possède des aubes à inclinaison variable (24a) dont l'inclinaison est commandée par le mouvement différentiel d'un arbre rotatif de commande (66) coaxial avec l'arbre de la turbine ainsi que par l'arbre de la turbine lui-même de sorte que l'angle d'inclinaison des aubes peut être modifié par un moteur stationnaire (116) sans avoir recours à des bagues collectrices ou autres accouplements enclins à l'usure. Dans le cas d'une défaillance de puissance, le mouvement rotatif de l'arbre de commande (66) est empêché de sorte que les aubes (24a) de la turbine sont rentrées uniquement grâce à la force développée par la turbine rotative (24). De même si la turbine est utilisée pour générer de l'énergie électrique, un générateur à induction (28) couplé à l'arbre (18) de la turbine est utilisé et dont la vitesse de l'arbre est une indication de la puissance de sortie du générateur. En conséquence, la vitesse du générateur est contrôlée et est utilisée pour commander le pas des aubes de la turbine de manière à maintenir la puissance de sortie du générateur à la valeur maximum lorsque la vitesse du vent est inférieure à la vitesse du vent nominale de la machine, et n'est pas supérieure à la puissance nominale de sortie lorsque la vitesse du vent dépasse la vitesse nominale du vent.

Abstract: In this rack drive, there is a stationary bearing housing (1), in which a pinion (7) or a drive shaft (20) connected fixedly to the pinion (7) is mounted rotatably, and a rack (11) which is held in engagement with the pinion by means of a guide part pivotable about the pinion axis. To simplify the construction and increase the load-bearing capacity of the rack (11), the bearing housing (1) has an inner bearing surface (10) equiaxial with the pinion (7) and in the form of an arc of a circle and the guide part is designed as a slideable supporting body (13) fitted between the spine of the rack (11) and the inner bearing surface (10). The bearing housing (1) can consist of two half-shells (2, 3), the circumferential walls of which form the inner bearing surface (10). The rack (11) passes through cut-out window orifices (12). The support body (13) preferably consists of a slideable plastic and also surrounds the flanks of the rack (11). It can be extended in a circumferential direction or be designed in the form of a complete ring. Instead of one, two oppositely directed racks (11) can also engage with the pinion (7) and are both pivotable independently of one another. <IMAGE>
