IPC: B22D39/00
Filed: 1983-11-22
Abstract: PURPOSE:To accurately maintain exhausting molten metal mount constant by increasing the width of the inflow side of a molten metal conveying passage which passes a movable magnetic field and reducing the frequency of a current supplied to an inductor at the standby time. CONSTITUTION:An eddy current is generated in a molten metal 2 in a body 1 by a moving magnetic field generated from an inductor 3 to apply a thrust to the metal 2.

IPC: H04N3/23
Filed: 1984-10-22
Abstract: PURPOSE:To make sufficient distortion correction and to simplify its adjustment by switching a parallel resonance circuit of a capacitor and a coil charged by a vertical deflection current based on a horizontal deflection pulse. CONSTITUTION:The horizontal deflection pulse is supplied from a terminal Hd to a shaping circuit 30, and a square wave is obtained from the circuit 30. This is supplied to the base of a TR24 through a transistor TR29 and a driving transformer 27. Consequently, the TR24 becomes the state of conduction, and a parallel resonance circuit is formed of a capacitor 19, a coil 21, diode 23 and TR24. In the case where a switching element 22 becomes the state of non-conduction, a distortion correcting vertical deflection current iD flows to the capacitor 19 through a deflecting coil 14 and a saw tooth voltage is obtained at a point P. By this saw tooth voltage, a parabolic wave current flows to the coil 14 superposing on vertical deflection current of a fixed value that does not contain distortion correction components.

Abstract: PURPOSE:To reduce the degree of color difference from an original image and to evade the reduction of the converting speed in a color space converting method by converting a 1st image data into a 2nd image data of another color space by means of the masking function that is selected in accordance with the 1st image data. CONSTITUTION:The image signal shown in an RGB color space is inputted, and the image signal shown in a CMY color space is outputted through the masking processing 12. That is, plural masking matrices are prepared at a color space converting part 1. Thus the optimum one of these masking matrices is selected when a hard copy is produced from the input image signal. Then all color data on an original image are converted and also an RGB luminance signal is converted into a CMY density signal. Furthermore the input signal and the output signal are not limited to the RGB luminance signal and the CMY density signal respectively. Thus a masking function is selected in accordance with the 1st image data of an optional color space, and the 1st image data is converted into the 2nd image data of another color space.

Filed: 1998-08-05
Abstract: PROBLEM TO BE SOLVED: To enhance a low elongation, a low heat shrinkage and a heat- resistance by constituting a warp of a reinforced cloth by a naphthalene type polyester fiber. SOLUTION: A warp of a reinforced cloth may be made of a naphthalene type polyester fiber yarn such as a polyethylene-2,6-naphthalate fiber (PEN) and it is not always necessary that a weft and other yarns are made of the naphthalene type polyester fiber yarn such as PEN. In the case where a yarn other than a naphthalene type polyester fiber yarn such as PEN is used as the weft, a nylon yarn such as 6-nylon, 6,6-nylon, 4,6-nylon and MXD-nylon (a polycondensation product of meta-xylenediamine and adipic acid) and a PET type yarn can be used and the nylon yarn is preferable from the point of view of a heat-resistance. A weaving method of the reinforced cloth is not particularly limited and may include any plain weave, straight warp weave (a weaving method in which a warp and a weft are disposed on a straight line and are entangled by an entangling yarn and are woven) and tire fabric.

Filed: 1996-08-06
Abstract: PROBLEM TO BE SOLVED: To substantially protective the appearance of a mis-touch or touch deviation by reading out the control value meeting the degree of depression of an expression pedal and controlling a dynamic range. SOLUTION: Every time there is an on-event of a key, the treading quantity of the expression pedal 13 is read in and the dynamic range 19 continuously changed according to the state of playing by controlling the dynamic range determined by a key velocity according to this treading quantity. The treading quantity of the expression pedal 13 is, therefore, read in by a control section 22 and the control value of the key velocity meeting the treading quantity is determined when the on-event of the key is detected and the key velocity is determined by a touch detecting circuit (velocity detecting means) 2. This control value is multiplied by the key velocity value and the compressed key velocity value is determined in an arithmetic section 21. The dynamic range is determined in accordance therewith.

Abstract: PURPOSE:To produce spherical metallic particles having a uniform size and shape by dropping a molten metal from a nozzle having a small bore in the form of a liquid drop and cooling the metal to solidify in an oil layer having a specific viscosity and a water layer under said layer. CONSTITUTION:A raw material 7 which is various kinds of metals or alloy is charged into an alumina crucible 3 and a C heater 4 on the outside thereof is heated by a high-frequency induction coil 5. The raw material 7 is melted by the heat thus generated. The molten metal is dropped from a nozzle 2 having 0.3- 3.0mm. bore provided at the bottom of the crucible 3 in the form of a liquid drop 8. The liquid drops 8 of the molten metal fall into an oil layer 12 having 10- 680 ISO.VG in a cooling cylinder 15 installed under the nozzle and since the cooling rate of the oil is low, the liquid drops 8 of the molten metal form a perfect spherical shape by surface tension. The spherical drops are quickly cooled to solidify in a cooling water layer 17 under the oil layer. The bore of the nozzle 2 is small and constant and the liquid drops are slowly cooled in the oil before entering the cooling water and therefore metallic particles 19 having a specified size and a uniform spherical shape are obtd.
