Corporate Brand

The acute angle and sharp straight edges of the top half of the

diamond symbol represent Yokogawa’s cutting-edge technology while

the gentle curvature of the bottom half represents the warm-hearted

nature of Yokogawa’s people. By balancing these two elements,

Yokogawa aims to contribute toward the realization of a thriving

global society in much the same way as the sun. This property is

reflected in the bright yellow of the diamond. !orporate trademark since "ctober #$%&

in describing "orte formation$

it separates' mo"es around the ob+ect and passes donstream, %t the point of contact ith the ob+ect' "orte sirls separate from the

bod! on alternating sides, his separation causes a local increase

in pressure and a decrease in "elocit! on one side and a decrease

in pressure and an increase in "elocit! on the opposite side, he

alternating "elocities generate alternating pressure forces on either side

of the bluff bod!, he freuenc! of these pressure changes is
