Title: Measuring method of liquid surface level
Inventor: KANAMORI KIYOSHI
IPC: G01F23/28
Filed: 1990-05-10
Abstract: PURPOSE:To calculate the level of the liquid surface by a method wherein thin light beams are projected to the liquid surface from above while the liquid surface is oscillated, and the regularly reflected light from the liquid surface is received by a photodetecting part of a laser distance sensor. CONSTITUTION:A liquid M is stored in a tank 1. A light emitting device 2 and a laser distance sensor 3 are provided confronting to each other above the liquid surface of the tank 1 provided with an oscillating means for oscillating the liquid surface. Each image sensor 6 constituting the laser distance sensor 3 is placed along the position where the laser beam from the light emitting device 2 which is regularly reflected by a light spot formed on the vibrated liquid surface forms an image. The laser beam is deflected in various directions according to the vibration of the liquid surface. Therefore, a part of the deflected laser beams enters a lens 5 even when the liquid surface is at such a height that the regularly reflected light does not enter in general. The reflected light at the liquid surface forms an image at the image sensor 6, and the level of the liquid surface can be calculated by an operating device from the position where the image is formed.

Title: Optical filter and optical wavelength multiplex transmission device using same
Inventor: SANO HIROHISA
IPC: G02B6/124
Filed: 1986-05-28
Abstract: PURPOSE:To reduce emission loss and to facilitate the manufacture by embedding >=2 kinds of materials which differ in refractive index from a waveguide in plural grooves formed in the waveguide. CONSTITUTION:The waveguide 3 which has a refractive index nH and a buffer layer 2 which has a lower refractive index nB than nH are formed on a substrate 1 which has a refractive index nS. A layer 4 with a lower refractive index nL than the nH and a thick clad layer 5 with a lower refractive index than the nL are embedded in the grooves provided periodically to the layers 2 and 3. The refractive index nL is so set regardless of the refractive index nS so that nL < nS and even when the light loss due to a leak of light to the substrate 1 increases, the light leak is reduced because of an exponential function decrease in the loss by an increase in the thickness of the layer 5, so that the difference between the refractive indexes nH and nL is increased optionally. Thus, while the emission loss is reduced, the size of the constitution is reducible and the manufacture is facilitated.
