Controller for working machine

TL;DR: In this article, two branched wave guides are formed on a substrate having optical anisotropy as ones for reference light and signal light and providing definite phase difference between interference lights respectively generated in a TE mode and a TM mode.

TL;DR: In this article, a plurality of fluid passages through which a fluid is circulated to a piston part provided in a cylinder, respectively, are provided, and a pressure fluctuation of the fluid is detected by performing difference computation of a pressure value detected by the plurality of pressure sensors.

TL;DR: In this article, a powder coating method which lessens the occurrence of environment problems and is capable of making mass production at a low cost by adhering powder directly to an oil-coated metallic surface and melting the powder by heat treatment, then cooling the surface to cure the melt.
