摘要:
A method of coating without permitting the coating solution to flow onto the side surfaces or the back surfaces of the lenses in the operation for applying the coating solution onto the lenses. A lens 15 is spin-coated with the coating solution having a particular viscosity. A side edge portion 121 of a spatula 119 is brought into contact with an upper edge portion of a side surface 15a of the lens 15 before the coating solution fed onto the surface of the lens arrives at the peripheral edge portion of the lens. The side edge portion 121 of the spatula 119 is so arranged that the upper end side of the spatula is tilted toward the center side of the lens 15 at an angle of 5 to 35 degrees with the vertical line as a reference. The coating solution applied onto the lens 15 that is rotating adheres onto the spatula 119 but does not adhere onto the side surface of the lens 15.

摘要:
A process for efficiently forming a thick coating layer having a uniform thickness on the surface of a base material having a curved surface. The process comprises the steps of forming a coating film having a predetermined thickness by applying a coating agent containing a polymerizable monomer on the curved surface of a base material, and then curing the coating film in an atmosphere of an oxygen concentration of not more than 500 ppm by photo-polymerization while substantially maintaining the uniformity of the thickness of the coating film. Preferably, the photo-polymerization of the coating film is carried out while rotating the base material at a rotational speed of from 20 to 1500 rpm.

摘要:
A device, method, and program stored in a recording medium are provided. A sampling time period and, a value of limit angle are set. Inclination of the projector device is detected with respect to a horizontal surface to output a plurality of inclination angle values of the projector device. A representative angle value of a current sampling time period is calculated based on the plurality of inclination angle values and the difference between the representative angle value and a representative angle value from a previous sampling time period is calculated. It is determined whether the difference in representative angle value is equal to or greater than the limit angle value to generate a determination result. Finally, trapezoidal distortion in the image is corrected based on the inclination angle values detected when the determination result indicates that the difference is equal to or greater than the limit angle value.
