摘要： A color picture display apparatus employs an array of light-emitting diodes or other light-emitting elements emitting different colors. A television signal is converted to monochromatic signals of the different colors. A color converter modifies the monochromatic signals, thereby changing the displayed hues to match the hues that would be displayed on a television screen, to compensate for ambient lighting conditions, or to achieve other desired effects. If each picture element has only a single light-emitting element, the modification preferably avoids unlit gaps in monochromatic areas of the displayed picture.

摘要： A method of expanding types of synchronous motors capable of reducing the number of required stator types to use stators in common, and a synchronous motor produced by the method. A group of stators are prepared by stacking stator cores of identical shape so that heights of the stators are different from one another to be multiples of a fundamental height. A plurality of groups of rotors are prepared so that lengths of the rotors in each group are different from one another to be multiples of a fundamental length. The rotors in each group are provided with permanent magnets having a residual magnetic flux density different from that of the permanent magnets of the rotors in the other groups. A stator and a rotor corresponding to a preset output torque specification value and a preset rotor inertia specification value are respectively selected from the group of stators and the rotor groups and are combined with each other, whereby an expanded type of motor is obtained.

摘要： A rotor (10) includes a plurality of permanent magnets (14) disposed around a shaft (12) at generally equal intervals, and a plurality of laminated core members (16) disposed between the permanent magnets (14) so as to form magnetic poles. The laminated core members (16) are formed by stacking a plurality of core-laminations (26) made of magnetic materials and an integral core-lamination, and joining them to each other. The integral core-lamination includes a plurality of core-lamination sections each having a shape the same as that of the core-lamination (26), and connecting portions (46) for connecting adjacent core-lamination sections with each other. When the large number of core-laminations (26) and the integral core-lamination are integrally joined by a press-fitting process, the laminated core members (16) are connected with each other in such a relative arrangement of a finished assembly that a space for locating the permanent magnet (14) is defined between the adjacent laminated core members (16), and thus an integral laminated rotor core (48) is formed.

摘要： A valve assembly in a piston type refrigerant compressor is disclosed. The valve assembly includes a retainer formed integrally with a gasket plate for restricting the opening of a discharge reed valve of the compressor, and having on opposite sides at the distal portion thereof stay portions integral with the gasket plate for rigidly holding the retainer. According to the present invention, provision is made to guide some part of the refrigerant gas compressed in a cylinder bore to be discharged into a discharge chamber in such a way that the influence of the discharge gas pressure on the retainer at its distal end is reduced. In some embodiments of the invention, this is accomplished by guiding and allowing part of the gas to flow toward the proximal portion of the retainer to discharge the gas.

摘要： Although a method for changing a combustion method taking place in an internal combustion engine depending on running condition is proposed, it can be considered that conditions under which a combustion noise occurs naturally differ with different methods. A detection method of prior art is not compatible with different combustion methods and the accuracy of combustion noise detection was low. Accurate combustion noise detection is enabled by identifying a combustion mode taking place in the internal combustion engine, selecting a sensed frequency or frequency band of a combustion noise sensor that detects a combustion noise in a combustion chamber of the internal combustion engine according to the combustion mode, and detecting a combustion noise.

摘要： In a cylinder injection engine and a control device for the engine, for achieving both of the decrease of a particulate matter by suppression of fuel adhesion on the piston during fast idling of cold start and ignition retard fuel by stratification of a mixed gas around an ignition plug, a closing timing of a suction valve is set to a middle stage of a compression stroke in which a piston moving speed becomes maximum, while the furl adhesion to the piston is decreased by injecting the fuel for stratification onto the ignition plug in the vicinity of a piston bottom dead center, and when the piston is raised in the compression stroke, the mixed gas flows from a combustion chamber to a suction pipe to generate a rising flow, and by this rising flow, the mixed gas is stratified around the ignition plug.
