Patent JP-S643336-A (JP)
Title: Braking device
Inventor: TOKUNAGA SHIGEAKI
IPC: F16D69/00
Filed: 1987-06-25
Abstract: PURPOSE:To keep off any slip between a road surface and a wheel attributable to a binding phenomenon lying between a braking disc and a brake shoe by installing each part, different in a friction factor, in the braking disc of a disc brake or the like, and altering braking effort between the braking disc and the brake shoe. CONSTITUTION:Each part 3 different in a friction factor is installed in a braking disc 1. Each of these parts 3 different in the friction factor is formed into almost the same type as a brake shoe 2 and they are set up at intervals of less than the maximum width of this brake shoe 2. And, material for these parts 3 different in the friction factor is made up of smaller substance in the friction factor than the braking disc 1 and embedded in this disc 1. Consequently, when the rotating braking disc 1 is pressed to the brake shoe 2, the braking disc 1 and these parts different in the friction factor are made contact alternately with each other, so that if brake locking is going to start in a part of the braking disc 1, the brake shoe 2 comes into contact with a part of these parts 3 different in the friction factor when it slightly rotates, whereby frictional force is lowered, permitting rotation of the braking disc 1 in consequence, thus skidding of a wheel on a road surface is preventable.

Title: Surface stress measuring device of vitreous coating
Inventor: KISHII KAN
IPC: G01N21/43
Filed: 1979-12-10
Abstract: PURPOSE:To measure the surface stress of a glass coating layer, by providing a  coherent light source, a light projection mechanism for projecting a coherent light  beam to the vitreous coating layer, and an emitting prism whose refractive index is larger than said coating layer. CONSTITUTION:An incident light beam 1 is projected to the vitreous coating layer 2 by the light projection mechanism, and an emitting prism 4 is stuck and installed on the coating surface 3. The incident light beam 1 is taken out by the emitting  prism 4, and it is converged to one point on the focal plane of the objective lens 5. In this case, when the surface stress exists on the coating layer, the position of the  boundary 8 of light and darkness is also different, and therefore, the surface stress  can be derived by calculating the difference of refractive index from these positions. As for actual porcelain enamel and glaze, however, the surface is not always plane,  and therefore, the accuracy cannot be obtained enough, but as a result of using a coherent light source, a thin interference fringe is formed on the focal plane, and the difference of refractive index is derived with sufficient accuracy by making the fringe a target.
