Title: Straight line generating method
Inventor: OSHIGE TAKAYUKI
IPC: G06T11/20
Filed: 1995-01-09
Abstract: PURPOSE: To generate a faithful straight line by performing interpolation without rounding decimal parts when start-point and end-point coordinates contain the decimal parts. CONSTITUTION: To generate a straight line by performing the interpolation between the start point and end point having the coordinate values containing decimal parts with dots having integral XY coordinate values, the coordinate value of a 1st coordinate between the X and Y coordinates is stepped in integer value units, the difference between the straight line connecting the start point and end point and the coordinate value of the other 2nd coordinate of the last obtained interpolation point is found by the coordinate values, and the coordinate value of the 2nd coordinate of the next interpolation point is determined on the basis of the difference or the sign of the difference.  This straight line generating method divides the X coordinate and Y coordinate by a number corresponding to the digits of the decimal part, further divides the divided sections into a number representing the difference in the coordinate value of the 1st coordinate between the start and end points as sections, and finds the difference between the coordinate value of the 2nd coordinate and the straight line on the basis of the start-point coordinates and uses the minimum devided unit to determine the coordinate values of the next interpolation point.

Title: Output device
Inventor: ENDO YOSHIYUKI
IPC: B41J19/18
Filed: 1996-01-09
Abstract: PROBLEM TO BE SOLVED: To improve the life of a position detecting means without supplying waste current by supplying power to the position detecting means of an output head only at the time of driving the drive source of an output head moving mean and stopping the supply of power to the position detecting means when the drive source is stopped. SOLUTION: When a control signal 21 is changed from an H level signal to an L level signal and the pulse motor 9 of a moving means is rotated, the signal 21 is inverted to the H level by an inverter 41. An analog switch 53 is conducted by the H level signal, and power source voltage is supplied from a power source Vcc 18 to a light emitting diode 47a of the position detecting means (photocoupler 47), and the diode 47a emits a light. Thereafter, when the signal 21 becomes the H level, the L level signal inverted by the inverter 41 is applied to the gate of the switch 53, and hence it is interrupted, the power source voltage from the power source Vcc 18 is not supplied, and the diode 47a is deenergized.

Abstract: PURPOSE:To provide an overload preventing device which has excellent responsiveness by a method wherein an axially movable worm gear is disposed on the power side and a worm wheel geared therewith on the load side, and through detection of a moving amount of the worm gear, a switch is operated to stop an electric motor. CONSTITUTION:When a load is hoisted by a winding machine torque is exerted on a worm gear 1 by a worm wheel 2. Though the worm gear 1 is moved over a worm shaft 3, the worm gear 1 is set so that a given moving amount is provided through regulation of the press force of a spring 4 by means of a regulating nut 5, whereby movement of the worm gear 1 is blocked in a case of low torque. However, when an overload is exerted and torque exerted on the worm gear 1 is increased to a value higher than the set press force of the spring 4, the worm gear 1 is moved over the worm shaft 3 to turn ON a switch 6f, and an electric motor is stopped. The press force of the spring 4, i.e., the moving characteristics of the worm gear 1, is varied by the regulating nut 5.

Abstract: PURPOSE:To make distortion of position of each motor to a frame by fixing each motor to the frame by an elastic semi-fixing device in respective area of a DD motor and a step motor making a straight line perpendicular to the direction of access of a magnetic head. CONSTITUTION:When a floppy disk device is installed in specified environment and ambient temperature changed conspicuously, a printed substrate 6 made of iron to which a DD motor 2 is mounted and a frame 1 made of aluminum alloy expands/contracts respectively as they are different in coefficient of linear expansion. Fixed points 20a, 20b (or 20c, 20d) of the printed substrate 6 to the frame 1 are fixed by parts including elastic washers 50, and therefore, the printed substrate 6 is in semi-fixed state. When conspicuous change in temperature takes place, the frame 1 and printed substrate 6 expand or contract independently at fixed points 20a, 20b. Accordingly, distorsion of positional relation between the frame 1 and substrate 6 to access direction X1-X1' of the magnetic head can be absorbed.

Abstract: PURPOSE:To make snow of superior quality artificially by a method wherein a spacing of a predetermined range is shielded against the surrounding atmosphere by a shielding member, a cold heat is supplied to keep the spacing at a temperature lower than a specified temperature and then a compressed air and water are injected through a spray nozzle. CONSTITUTION:A spacing within a predetermined range of a region to be covered by artificial snow is shielded against the surrounding atmosphere by a shielding member 1 composed of a side wall 1a and a top wall 1b. A cold heat supplying nozzle 2 and two-fluid spraying nozzle 3 are fixed to a top part of the side wall 1a. The cold heat attained through a liquefied air, liquefied nitrogen and liquefied carbonate or the like is blown into the shielding member 1 through the cold heat supplying nozzle 2 via a conduit 6 so as to keep a temperature within the shielding member 1 less than -5 deg.C. Water and compressed air are injected through the two-fluid spray nozzle 3 and the water drips are cooled by the cold heat to become snow 9 and the snow is accumulated on a ground surface 8 within the shielding member 1. It is required that the water droplets to be injected have a substantial mean particle diameter less than 200mum. Particle diameter of the water droplets is made to small and uniform, thereby a heat exchanging rate with the cold heat is improved, the water droplets are efficiently cooled and the snow quality is not disturbed and the snow of uniform quality can be made artificially. This operation is repeated in sequence to make snow over an entire ski field.
