Patent EP-0419760-A2 (EP)
Inventor: CIRAULA MICHAEL KEVIN
IPC: G11C17/16
Filed: 1990-05-03
Abstract: A fused, redundancy selection circuit (20) is disclosed which is disabled by the absence of a chip select signal (CS). The circuit has the feature of avoiding the use of nodes with a floating potential and in this manner it provides an enhanced radiation hardened characteristics. The circuit is effectively disabled if no redundancy is required on a particular memory chip, by leaving fuses which are a part of the circuit, intact. Alternately, if the memory chip is tested to have defects, the redundancy circuit (20) is selectively enabled to provide the desired redundancy for the chip, by blowing fuses which are a part of the circuit. Thereafter, the redundancy circuit is now an active part of the memory chip and it is selectively enabled when the chip select signal (CS) is applied to the chip. An advantageous feature of the circuit is that it does not dissipate power when its function is not required either because its enabling fuses have not been blown or alternately when the chip select signal is off. In this manner, a zero standby power, radiation hardened memory redundancy circuit has been provided.

Abstract: Disclosed is a chucking device for chucking a drum (A) to keep it vertical while the drum is immersed in a coating liquid to be coated with the coating liquid. The chucking device comprises upper (20) and lower (30) pressure members having tapered peripheral surfaces (22a, 31a) at their ends facing each other. An annular elastic member (70) is fitted between the tapered peripheral surfaces (22a, 31a). The pressure members (20, 30) are constantly urged toward each other. When chucking a drum (A), the lower pressure member (30) is moved away from the upper pressure member (20) by means of compressed air so as to contract the elastic member, thereby allowing the pressure members (20, 30) and the elastic member to be inserted into the drum (A). Then, the compressed air is released, allowing the pressure members (20, 30) to contact each other. This causes the elastic member (70) to be pressed outward by the tapered peripheral surfaces (22a, 31a) to tightly contact the inner surface of the drum (A). Then, the drum (A) is moved upward together with the elastic member (70) until it abuts against a positioning portion of the upper pressure member (20).

Abstract: In this measuring device, the angle scale (4) of a dividing plate (2) is scanned by a scanning unit through the movement of a light beam in two diametrically opposites angle scale ranges (10, 11). In order to compensate wobble errors due to the wobbling of the dividing plate (2), the light beam (9) emanating from a light source (5) impinges outside the angle scale (4) at the point (A') on the dividing plate (2), and then impinges as the light beam (9'), parallel to itself after reflection and deviation by a triple prism (7), at the point of impingement (B') on the angle scale (4) in the first angle scale range (10). The light beam (9') is split by the angle scale (4) into two reflected diffracted beams (9a', 9b'), which reunite in the second angle scale range (11) at the reuniting point (C') on the angle scale (4) after passing through a deflecting prism (6). Since the point (B') of impingement and the reuniting point (C') always lie on the same radius even in the event of wobbling of the dividing plate (2), wobbling errors cannot disadvantageously effect the measurement accuracy (Figure 1).

Title: Tape driving mechanism for magnetic recording apparatus
Inventor: KUROKAWA HIDEO
IPC: G11B15/29
Filed: 1991-08-27
Abstract: A tape driving mechanism for a magnetic recording apparatus wherein a capstan (1) is rotated to advance a magnetic tape (3) by pinching the magnetic tape (4) between the capstan (1) and a pinch roller (2). The pinch roller (2) is pressed onto the magnetic tape (3) against the capstan. The capstan surface is coated with a diamond-like carbon film (4) which is smooth and highly wear-resistant. The difference between the tangential speed of the capstan and the tape transfer speed is almost zero; thus, the state of contact is static. A static frictional coefficient between the diamond-like carbon film (4) of the capstan (1) and the magnetic tape (3) is almost equal to twice the static frictional coefficient between the metal surface of the capstan and the magnetic tape in the conventional tape driving mechanism. The tape driving force remains sufficient, if the pressure exerted by the pinch roller (2) is reduced to half the value employed in the conventional tape driving mechanism. The diamond-like carbon film (4) may be coated on a rough surface of the capstan (1).

Abstract: The present invention relates to a method and to an apparatus for interfacing smart cards with any terminal. 
     The memory capacity and the features of smart cards are increasing exponentially. Therefore a terminal with a card reader designed today will hardly be able to follow future evolution of smart cards. 
     The invention uses a process which allows efficient use of the smart card capacities by actual terminals. This process is based on the following architecture: A terminal equipped with a display, a pointing device (e.g. a keyboard), a smart card reader and a smart card are combined together. The terminal must have the following capacities which are quite normal:
     to display a list of action which will be described in ASCII characters;   to select actions;   to enter key sequences;   to display messages and clear them afterwards.   
     A communication protocol between the smart card and the terminal is implemented in the terminal comprising special commands.

Abstract: A high order interpolative oversampled (sigma delta) analog-to-digital converter network including a plurality of cascade-coupled integrator stages (22,24,36) is formed on a single integrated circuit chip in a manner that conserves power and chip area. Each integrator stage (22,24,36) includes a differential amplifier, at least one input capacitor and at least one feedback capacitor. The power dissipation and occupied chip area are minimized by down-sizing the chip area occupied by the capacitors and differential amplifiers (op amps) in all but the first integrator stage. The high gain of the first integrator stage makes the noise contribution of subsequent integrator stages negligible so that the higher noise of the subsequent integrator stages is tolerable.

Abstract: The present invention relates to a structure of positioning a cathode ray tube (8) in a cabinet of a television receiver (10). In the television receiver, at least one portion of each of front window frames (10a,b,c,d) of the cabinet (10) for positioning the cathode ray tube (8) therein is formed as to be elastically deformable outwardly due to a contacting relationship between the cathode ray tube (8) and the cabinet (10) when assembling them. Because at least one portion of each of the front window frames (10a,b,c,d) is elastically deformed, a variation in a dimensional relationship between the cabinet (10) and the cathode ray tube (8) caused when securing the cathode ray tube (8) to the cabinet (10) can be compensated. Preferably, the front window frame (10a,b,c,d) is formed in such a manner that a thickness thereof is gradually reduced from the proximal end (10A) toward the free end (10B).

Abstract: Digital signals are generated and stored for each pixel of a frame of a preferably high definition video originated material. A computer (7) reads the digital signals and converts them to binary image data by employing a selected look-up-table program (10) to reassign color and black component values for each pixel. The programs applied in the component value reassignments are compiled from, and based on, comparative digital video component results of telecined film stocks' responses to selected color and grey scale gradients as charted against a selected video unit's response to the same charts under a selected number of identical lighting circumstances. The revised digital data is assembled and converted to an analog signal for a secondary modification wherein: A projector unit (21) projects the high definition video frame through a macro lens (23) onto a strip of exposed and processed motion picture or other photographic film of an optional grey scale gradient and thus grain pattern density. An automatically variable filter (40) over the projector lens (23) compensates to maintain the same brightness result from the opposite side of the film surface. A precisely aligned, compatible high definition camera unit (22) provides a synching signal to the projector (21) and automatically frames and focuses on the projected image from the reverse side of the celluloid surface (36), scanning the projected scan lines, to output the grain-embodying image for recording and displaying on a high definition format or external conversation to NTSC for broadcast purposes.

Abstract: In a device for attaching printing plates, kept in register, on plate cylinders of rotary printing machines, the object consists in designing printing plates which are arranged adjacently in the axial direction to be individually adjustable in the axial direction using a narrow cylinder gap. According to the invention, this object is achieved in that the bent ends of the printing plates, held in the cylinder gap, are guided in register pins which are located on insert strips arranged in a cylinder groove, the insert strips being constructed to be clampable and displaceable. The individual adjustability of each printing plate is directly appropriate for the different supply of damping medium.
