Title: Production of flash type optical waveguide element made of organic crystal body
Inventor: KONDO TOSHIYUKI
IPC: G02B6/13
Filed: 1989-07-20
Abstract: PURPOSE:To provide an element which hardly receives mechanical external forces by constituting the element by a stage for producing the ridge type optical waveguides made of an org. crystal body, a stage for forming a layer consisting of a material having the refractive index lower than the refractive index of the org. crystal body and a stage for removing a resist and the layer consisting of the material having the refractive index lower than the refractive index of the org. crystal body on the resist. CONSTITUTION:The ridge type optical waveguides made of the org. crystal body are produced by applying a resist 3 sensitive to light to electron beams on the thin-film org. crystal body 2 formed on a substrate 1, exposing and developing the resist to a desired fine pattern, then etching the thin-film org. crystal body 2. The layer 4 consisting of the material having the refractive index lower than the refractive index of the org. crystal body 2 is formed by vapor deposition or sputtering on the optical waveguides made of the org. crystal body and the substrate in such a manner that the this layer is formed to the same film thickness as the film thickness of the org. crystal body 2. The resist 3 on the optical waveguides made of the org. crystal body and the layer 4 consisting of the material having the refractive index lower than the refractive index of the org. crystal body on the resist are then removed. Consequently, the element is substantially kept free from the mechanical external forces. and the scattering loss of the light is decreased.

IPC: G10H1/18
Filed: 1992-07-17
Abstract: PURPOSE:To generate a sound at timing corresponding to the feeling of key operation by a player without any unnecessary sound generation allocation and sound generation delay. CONSTITUTION:This instrument uses a keyboard 5 provided with a position detecting means which detects a shift in the position of each key over the overall stroke of the rotation by keying. A CPU 1 detects the position of each key which changes momentarily by the position detecting means, calculates the operation speed of each key from the shift in the position, and decides whether or not the operation speed of the key is larger than the critical speed at the position of the key. Then a CPU 1 assigns the generation of a new musical sound to one of sound generation channels of a musical sound synthesizing circuit 9 according to the decision result and instructs the generation start of a musical sound signal to a musical sound synthesizing circuit 9 according to the operation speed and decision result of each key. Consequently, the musical sound synthesizing circuit 9 starts generating the musical sound signal at timing instructed by the CPU 1 from the assigned sound generation channel.
