Abstract: An RF power source apparatus comprises: a switching power source (12) that has a control unit (122) which produces control signals of a predetermined frequency which can be turned on intermittently, and which can be arbitrarily set while the control signals are continuously turned on, a switching unit (121) which receives a direct current and which is turned on or off in response to the control signals to produce the direct current as intermittent pulses, and a rectifying'smoothing unit (123) which rectifies and smoothes the output of the switching unit (121) and produces it as a direct current; and an RF inverter (13) which receives the direct current from the switching power source (12) and produces an RF current. The RF power source apparatus is effective in generating a laser beam for pulse drive.

Abstract: In a single-lens reading glass whose dioptric power DLG = 1000/focal length is in the region of 6 dpt to 24 dpt, and which has at least one aspherical surface, this aspheric surface is rotationally symmetrical and has a meridional section whose sagitta p (h) is described as a polynomial which has only even powers of h and whose first term h2 represents a conic section. The aspherical surface is arranged on the eye side, while the object-side surface is spherical and has a surface dioptric power Dobj which is a function of the dioptric power DLG of the reading glass. This reading glass has very good imaging characteristics for use without reading spectacles or without or virtually without accommodation, i.e. in the range of its highest magnification. These characteristics change only very slightly for a change in the conditions of use within specific limits. <IMAGE>

Abstract: In this parallel gripper suitable for gripping a work for a robot or the like, in which a pair of fingers (16) are opened and closed by keeping the parallel condition between them by the transmission of the driving force of a fluid pressure actuator to the fingers by means of a power transmission mechanism, use are made of a pair of pistons (6, 7), that are relatively slidable in a single cylinder bore (2) under the action of fluid pressure, as the fluid pressure actuator, thereby obtaining substantially twice as large gripping force as in the case of employing a single piston. 
     Further, simplification in constitution and reduction in weight of the parallel gripper are achieved by constructing the gripper so as to supply a pressurized fluid to the pressure chambers (10, 11) formed between the pair of pistons (6, 7) in the cylinder bore (2), and by transmitting the driving force of both pistons that are driven in the mutually opposite directions to the fingers by means of a simple power transmission mechanism which employs levers (23) as its principal components.

Abstract: An immunoassay method involves the use of one or preferably two enzyme amplification steps to increase assay speed or sensitivity. In a first step, a first enzyme is generated in an amount related to the concentration of an analyte in a sample. In a second step, the first enzyme acts on a first substrate to reveal antigenic determinants of a first product. In a third step, the first product is reacted with an antibody. The extent of this immune reaction is determined, preferably by means of an enzyme signal system. Two assays for digoxin and one for 17α-­hydroxyprogesterone all using beta-galactosidase as the first enzyme are described.

Abstract: The invention relates to devices for converting images into electrical signals, and applies in particular to radiological image registration. 
<??>Instead of building up on a glass insulating substrate (30) a strip or an array of photosensitive elements (p-i-n photodiodes 38, 40, 42) which are then covered with a scintillator sheet stuck or pressed against the upper surface of the photosensitive elements, a scintillator layer (32) is deposited on the substrate before forming the photosensitive elements. 
<??>It is thus possible to improve sensitivity and resolution. It is moreover possible to preserve, in addition to the scintillator layer deposited between the substrate and the photosensitive elements, a scintillator layer stuck or pressed to the upper surface of the whole; the two scintillators may be identical or different in kind; if they are different they can react to different wavelengths and also emit at different wavelengths.

Abstract: Conventional electrical or electronic detonators for projectiles with an electromagnetic generator have too high a current consumption to ensure delay times of over 15 seconds, with the result that the usual mechanical detonators cannot or can rarely be replaced. Now an electrical projectile detonator is presented which has a single low- frequency RC oscillator and a pulse counter, the outputs of which provide control signals for fore-tube safety, penetration delay and for the self-disintegration of blind shells, delay times of the order of several minutes being obtained without any problems. A programmable logic circuit with interconnected logic gates selects the desired delays by connecting to the associated output of the pulse counter, and passes the control signal on to the pyrotechnical release mechanism. <IMAGE>

Title: Palier à film fluide et son procédé de réalisation
Inventor: RIAZUELO SERGE
IPC: F16C17/12
Filed: 1989-09-18
Abstract: L'invention se rapporte à un palier à film fluide et à son procédé de réalisation. L'invention concerne un palier à film fluide hydrodynamique formé entre une pluralité de feuilles (3) solidaire d'un fourreau (5) et un arbre (6) en rotation par rapport audit fourreau. L'invention a pour but de totalement dissocier le réglage de la raideur radiale du palier dans la phase de démarrage et celle dans la phase de rotation à vitesse de travail. Une raideur faible, négligeable ou nulle des feuilles (3), permet de limiter les forces d'application des feuilles sur l'arbre et ainsi de diminuer l'usure au démarrage du palier. Après le démarrage, la mise en rotation de l'arbre (6) à l'intérieur de la feuille (3) provoque un déplacement des feuilles (3) qui s'écartent de l'arbre (6) par interposition d'un film d'air hydrodynamique. La nouvelle position occupée par les feuilles (3) entraîne une reprise de l'effort des feuilles (3) par des éléments de contrainte (4), comme par exemple des ressorts à lames (40, 41, 42 ou 43). L'invention s'applique notamment à toutes les applications classiques de paliers à film fluide de type connu, comme par exemple les moteurs ou les machines tournantes équipant les aéronefs. L'invention s'applique d'autre part à la réalisation de paliers susceptibles de tourner à basse vitesse, et/ou susceptibles de supporter des charges élevées.

Abstract: A frequency detector is used with a digital scanning converter that enables a monitor receiver having a particular horizontal deflection frequency to monitor various video signals having difference horizontal frequencies. The frequency detector has a counter (18) for counting a reference clock (F) during a predetermined time interval derived from an input signal (HD) to be measured and a computing circuit (21) for adding or subtracting a first constant (α) to or from a setting cycle (y) in response to a difference (z) between a count value (x) of the counter (18) and the setting cycle (y). When the difference (z) exceeds a second constant (β) during a predetermined number of such time intervals, the setting cycle (y) is adjusted by an output from the computing circuit (21), and an approximate value of the period of the input signal (HD) is computed, thereby detecting the approximate frequency. This process goes through as many iterations as necessary to bring the difference (z) to a value less than the second constant (β). Even when the frequency of the input signal (HD) is one of a number of greatly differing values, the frequency detector can home-in on the period of the input signal (HD) and enables detection of the frequency with high accuracy.

Abstract: A video processing system for use in combining a first video image sequence comprising a number of image frames and a second sequence of video image frames to create a composite video image sequence is disclosed. The system comprises a stylus and touch tablet combination and is arranged to define on a frame-by-frame basis at least four reference points representing corners of a keyframe in three dimensional space notionally projected onto a monitor screen. A transforming circuit transforms the addresses of pixels in a frame of the first video image sequence so as to cause the pixels to represent the frame as projected onto the display screen from the same location in three dimensional space as the keyframe. A combiner combines the transformed frame with a corresponding frame of the second video sequence to produce the composite video image sequence.
