Abstract: In carving a decorative groove (7) formed in V-shape cross section extending from inside to outside on a dial plate (2) of a timepiece as a decorative plate, the slant angle of an inner slanted side (7A) forming the V-shape of the decorative groove (7) is made gentler than an outer slanted side (7B) at an inner part of the spiral, so that action of light reflected on the flat surface of the dial plate (2) macroscopically becomes similar to the light reflected on a bulging surface to give the central portion of the dial plate (2) a bulging appearance, whereby a three-dimensional effect is provided by the decorative groove (7) even when the dial plate (2) is made of a thin plate, thereby adding depth and a luxurious touch or aspect.

Abstract: A gage connected to the rod end of the wing cylinder on a multi-section implement senses rod end pressure at the output of the hydraulic wing control (HWC) valve. The HWC valve is engaged or disengaged using the selective control valve (SCV) in the tractor, and the gage provides a visual indication to the operator of the following modes: 1) off; 2) fold wings; 3) unfold wings; 4) field operation--push wings down; and 5) field operation--pull wings up. In field operation, the gage also provides an indication of the force with which the cylinders are pushing or pulling on the wings to affect the cutting force of the wings.
