Title: Forming method for optical waveguide
Inventor: SAWAKI IPPEI
IPC: G02B6/122
Filed: 1986-12-20
Abstract: PURPOSE:To prevent a light beam from diverging from a waveguide, by diffusing a substance for lowering a refractive index of a substrate, along the outside periphery of a curved part of the waveguide having the curved part, so as to be roughly in parallel to said outside periphery. CONSTITUTION:The first Ti metallic pattern 4 is formed on an LiNbO3 substrate 3 and a thermal diffusion is executed, an optical waveguide 5 is formed, and a first diffusion area is formed. Subsequently, an MgO pattern 7 is formed on the outside periphery of a curved part of this waveguide 5 and a thermal diffusion is executed, and a second diffusion area 8 is formed. As a result, on the substrate of the curved part of the waveguide, a refractive index gradient for lowering a refractive index of the outside periphery side is formed, and a difference of the optical path length of the inside periphery part and the outside periphery part of the waveguide is compensated, therefore, divergence of a light beam in the curved part can be prevented. Accordingly, a radius of curvature of the curved part can be made much smaller, and the degree of integration of an optical circuit element can be improved.

Filed: 1986-12-22
Abstract: PURPOSE:To realize the handwriting input of information with all types of input means including a finger, a ball pen, etc., by attaching a writing pressure detecting resistance sheet onto an input coordinate detecting resistance sheet. CONSTITUTION:When an input panel 1 is pressed by an input means 12, the X and Y coordinate positions detected as electric signals are delivered to an input coordinate detecting interface 7 from the input coordinate detecting resistance sheets 2 and 3. While the DC voltage is applied between the writing pressure detecting resistance sheets 13 and 14. Thus a current flows when a contact is secured between both sheets 13 and 14 at a point P where the means 12 is pressed. Then a writing pressure detecting interface 9 detects said current and delivers a writing pressure detecting signal to a control part 10. Thus it is possible for the part 10 to display the relevant coordinates at a display part 11 regardless of the type of the input means as long as an OR is secured between the input coordinate signal and the writing pressure detecting signal.
