Abstract: PURPOSE:To prevent errors due to temperature change by controlling a current so that the light generating amount of a semiconductor light source which generates monochromatic light is constant, while obtaining the wavelength based on the current value, and correcting a scale factor. CONSTITUTION:Monochromatic light from a light source 1 is split into two light beams in an interference optical system 2. The light beams are inputted into a photodetector 3 by way of the different paths. Then the phase difference thetaof the interference light beams is obtained in a signal detecting circuit 4. The difference is divided by a scale factor, and the intended physical quantity is obtained. The scale factor is the function of a wavelength lambda. The wavelength lambdais changed with temperature. The value is corrected as follows. An amount P of generated light is found through a half mirror 13 and a photodetector 14. The current of the semiconductor 1 is controlled so that the generated light amount P becomes constant with a control part 8. The current value is obtained with the voltage drop in a resistor 9. Since the wavelength lambda is determined based on the current value, the scale factor is corrected with a correcting circuit 11.

Title: Drainage structure in bathroom
Inventor: YAMADA TAKAO
IPC: E03C1/12
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To lessen the residue in a drainage even when drain is a little and sufficiently wash bubbles out by forming the sectional shape of the drainage so as to make narrower the breadthwise width of the ditch bottom than that of the upper end opening in the upstream side and make wider the breadthwise width of the ditch bottom in the downstream side. SOLUTION: The drainage 5 is formed to have a V-shaped section in the upstream thereof so that water is hardly disconnected and the breadthwise width L of the ditch bottom of the drainage 5 is widened as it goes to the downstream. Accordingly, water does not spread widely on the ditch bottom 5C even when drain is a little in the drainage 5 in the upstream where only a relatively small quantity of drain flows in, and the contact resistance against the ditch bottom 5C is small and water continuously flows without disconnection in the midway of the stream. In the drainage in the downstream, as bubbles do not touch the side wall 5D of the drain ditch and the quantity of water increases compared with the upstream, the water stream is not disconnected. In this way, even when drain is a little, the residue in the drainage can be decreased.
