Abstract: A system and method for controlling operation of a plurality of elements in an automated process, such as a production process, and indicating error conditions as they occur. Each unique set of input and output conditions of the various system elements defines a unique logic state or zone. Thus, there are defined a multiplicity of valid system logic states or zones, each having a unique input/output image. A predetermined sequence of zones, productive zones representing designed machine operations, is stored in a zone table. All zones not explicitly defined in the zone table are automatically treated as error zones. A zone engine automatically cycles to observe any change in input/output image. Any change in inputs from the various system elements automatically transfer action to the unique zone associated with such inputs, resulting in corresponding changes in control outputs to the system elements and/or display an error message as appropriate.

Abstract: This discharge lamp includes (i) an inner envelope (12) of vitreous material comprising a bulbous portion (14) and two tubular portions (16, 18) extending from the bulbous portion and (ii) a tubular shroud (20) of vitreous material surrounding the bulbous portion and the two tubular portions. The lamp is made by the following method. A disk-shaped enlargement (30) is formed in at least one of the tubular portions by heating a localized region of the tubular portion to its softening point and then subjecting said localized region to a compressive force (i) that is abruptly applied along the length of the tubular portion and (ii) that drives the softened vitreous material radially outward into a disk formation. Then the tubular shroud is placed over the inner envelope so that each disk-shaped enlargement is positioned with its outer periphery closely adjacent the inner periphery of the surrounding tubular shroud. Then seals are formed between the outer peripheries of the disk-shaped enlargements and the surrounding shroud portions by heating each of the surrounding shroud portions to its softening point and collapsing it about the outer periphery of the associated disk-shaped enlargement.

Abstract: A passively mode-locked laser (110) includes a resonant cavity (112, 114) having a gain medium (116) therein. A transmissive element (116), which may be the gain medium, is also located in the cavity and is formed from a material which varies the two-dimensional, laterial spatial profile of the beam with respect to intensity due to the Kerr effect. The resonator is arranged such that the round trip gain of the system increases with respect to the intensity of the beam so that the mode-locking operation can be achieved. In one approach, the variation in the spatial profile is used to increase the extraction of energy from the gain medium. In another approach, the variation in spatial profile which occurs with an increase in intensity is used to decrease the loss introduced by a stop (128) in the system so that pulse operation is favored. The gain medium (116) is formed from titanium-sapphire, and the self-phase modulation of the crystal is also used to compress the pulses into the femtosecond range. A prism set (136,138) can be used to balance the group velocity dispersion and self-phase modulation of the gain crystal (116) to achieve stable, soliton-like operation. In the preferred embodiment, mode-locking behavior is initiated by rotating a transmissive optical element (230,232) located in the cavity in a manner to vary the path length of the beam.

Abstract: A multiprocessor having a plurality of microprocessors (38,40) includes an OR gate (36) for ORing read signals (46,48) from the microprocessors, and a unit (32) for receiving an output signal (52) from the OR gate and producing an initial processing permission signal (50), thereby determining one microprocessor to conduct an initial processing for a shared circuit (44). In concurrence with the operation monitoring the initial processing permission signal, each microprocessor simultaneously outputs a read signal (46,48). The OR gate (36) generates an output signal (52) on receiving a read signal. This changes the initial processing permission signal (50) thus produced by the unit (32) from the permission state to the inhibit state. Each microprocessor monitors the initial processing permission signal to conduct the initial processing for the shared circuit only when the signal is in the permission state. Even when one microprocessor is in an abnormal state, the multiprocessor system can be set to the operable state by another microprocessor.

Abstract: The present invention is directed to a tape reel in which a thin flange portion is formed by reducing a thickness of each of front and rear flange surfaces of the tape reel and a thick portion having a thickness larger than that of the thin flange portion is formed on a plurality of places of an outer periphery of the flange portion. When the tape reel is molded by using a molding metal mold, a pin is inserted into the molding metal mold at a portion corresponding to a portion where a resin is filled into the thin flange portion last, and air and gas within a cavity are discharged from a spacing formed between the molding metal mold and the pin. Thus, the occurrence of short mold and weld line on the thin portion of the tape reel thus molded can be avoided and a rotational fluctuation of the reel flange surface can be avoided. 
     Also, the present invention is directed to a tape reel in which front and rear surface portions of each of upper and lower flanges are formed as thin flange portions by uniformly reducing the thickness of each of the front and rear surface portions thereof except outer peripheral edge portions thereof and radial tape position restricting ribs 7 are formed on tape contact flange surfaces of the upper and lower flanges. Thus, the flanges can be prevented from being warped even when the thicknesses thereof are reduced. The tape reel can be made light in weight and the material therefor can be saved. Also, the tape reel of the present invention can achieve a similar action to that of the conventional tape reel.

Abstract: According to the present invention, a self-diagnosis system for an image forming apparatus can make accurate fault diagnosis and is made smaller in size and higher in speed. For that purpose, a fault temporarily developed by the image forming apparatus is limited to a single fault assumption, all states which can exist on the image forming apparatus when the image forming apparatus develops the fault are previously simulated, and the results of the qualitative simulation are stored as a plurality of virtual cases in a virtual case storing portion 12. When the image forming apparatus is operated, detected values of sensors X, Vs and Ds are converted into fuzzy qualitative values, respectively, on the basis of membership functions stored in a membership function generating portion 13. The fuzzy qualitative values are compared with the virtual cases stored in the virtual case storing portion 12, to reason the cause of the fault. Accordingly, any of the virtual cases stored in the virtual case storing portion 12 is selected using the fuzzy qualitative values, thereby to make it possible to accurately specify the fault in a short time.
