    摘要: A position-data converter and a motor-drive control device are connected. The position-data converter receives two-phase, sine-wave analog signals da and db from two first magnetic detectors, respectively, and converts these signals da and db to position data. On receiving a positioning instruction, the motor-drive control device calculates the value of current, from the current position signal generated by the position-data converter. The permanent magnets incorporated in a linear motor are used as components of a linear scale, as well.

    摘要: To provide a grounding structure for connecting and fixing a printed circuit board and a conductive frame to a conductive chassis of an electronic apparatus, the height of solder applied to the grounding land is made uniform, thereby ensuring electrical connection between the printed circuit board and the conductive chassis. A copper-foil coating 54 formed on a printed circuit board 50 is divided by a substantially-lattice-shaped resist 55 to form a grounding land 56 including a plurality of obliquely elongated land elements 56c in an area close to the edge of an opening 51 and a plurality of rhombic land elements 56a in the remaining area, and the grounding land 56 is brought into contact with and screw-clamped to a conductive chassis 60 using a locking leg 41.

    摘要: In fuel gasification, particles of, for example, coal and an oxidant are supplied to a reactor, where the coal particles are gasified. The gas thus produced may contain molten slag entrained therein and such slag could subsequently solidify and affect other components of the coal gasification apparatus. Therefore a molten slag cooling heat exchanger is positioned directly above the reactor and this cools the gas so as to cause any molten slag therein to solidify. Hence, such molten slag does not reach an evaporator above the molten slag cooling heat exchanger, so that the efficiency of the evaporator will be maintained. However, solidified molten slag may build up on heat exchange tubes of the molten slag cooling heat exchanger. Therefore, the rate of coolant supplied to the molten slag cooling heat exchanger is varied, to cause expansion and contraction which causes solidified slag to be dislodged. Hence the efficiency of the molten slag cooling heat exchanger does not deteriorate. Cleaning gas and coal particles may be jetted onto the evaporator to dislodge ash or soot therefrom.

    摘要: A pair of through holes are formed in a circuit board, and a silver paste filled up in the through holes connects lands formed on a front surface and a rear surface of the circuit board, respectively to each other. When the silver paste is solidified, the silver paste bulges curvedly from the front and rear surfaces of the circuit board and forms a bump. A surface of the bump is covered with an overcoat. An electronic component is brought into contact with the bump, thereby forming a degassing gap between the electronic component and the circuit board. A gas generated during soldering is discharged from the penetrating hole, into which the lead terminal is inserted, to an outside via the gap between the electronic component and the circuit board.
