Title: Elliptical arc display processing method
Inventor: KEZUKA EMIKO
IPC: G06T11/00
Filed: 1987-07-09
Abstract: PURPOSE:To display always correct elliptic arc by dividing an elliptic arc, in case of generating the display data of the elliptic arc by designating a start point and an end point, when its angle of circumference is larger than a prescribed value, and generating the data of thus generated divisional elliptic arcs. CONSTITUTION:In case of generating graphic display data 5 out of the elliptic arc data of graphic data 3, a display processing part 4 discriminate whether the circumference angle of the arc is larger than a prescribed value or not by using the designated coordinate values of the center, the start point, and the end point of an ellipse. If the prescribed value is selected to be 180 deg., said decision of the angle is comparatively easy. If the circumference angle is within 180 deg., the graphic display data is directly generated. If larger than 180 deg., a suitable division point is provided on the elliptic arc to divide the arc into a divisional arc from the start point to the division point and another from the division point to the end point, and data that designate the respective arcs is generated. As a result, a correct elliptic arc can be always displayed irrespective of the accuracy of a display device.

Title: Method for generating dc arc
Inventor: NARISEI TORU
IPC: H05B7/144
Filed: 1992-06-04
Abstract: PURPOSE:To rotate arc around an electrode central line to ease the magnetic force causing the curve of the arc, and stabilize the arc by supplying a current to current-carrying passages radially formed around the electrode central line in order. CONSTITUTION:When a current is carried to any of four leads 5 of a radial wiring part 6, the magnetic field generated thereby is generated vertically to an arc A and attracts the arc A closer to the opposite side to the leads 5 by the magnetic force with the lead 5. Currents A-D are carried to the leads 5 in order, whereby the arc A can be rotated around the electrode central line to ease the magnetic force causing its curve, and stabilize the arc. Even when the arc length is extended to increase voltage, the arc is stabilized, and a power source can be highly efficiently utilized. Since no gas is used fro stabilization, operating cost is low, and the electrode peripheral equipment can be simplified.

Abstract: PURPOSE:To shorten heating period of time by providing an arithmetic means and a control means by which temperature of hot water in bath tab is measured when the bath tab is filled with hot water having a final bath water temperature up to a specified water level, and then hot water having a temperature calculated based on a particular formula is supplied to the bath tab up to a final water level. CONSTITUTION:After a final bath wager level H0 in a bath tab 30 and a final bath water temperature T0 are set by a control device 31, water is heated by a hot water supply heat exchanger 17 at the same flow rate that a circulation pump 26 sends water to the bath tab 30. When the water level in the bath tab reaches a specified level H1, hot water temperature T1 is measured by a bath tab water temperature detector 28. A hot water temperature is calculated by an arithmetic means 32 according to a formula; (T0 X H0 - T1 X H1) divided by  (H0 - H1). Hot water having the calculated temperature is supplied up to the final bath water level H0 by the control device 33. When hot water reaches the final bath water level H0, hot water temperature is measured again by the detecting device 28. When the temperature reaches the final bath water temperature T0, the operation is stopped. When it does not, water is heated by an additional heating heat exchange 24 till the water temperature reaches T0 and then the operation is stopped.
