Title: Disc brake
Inventor: MATSUZAKI MIKIO
IPC: F16D65/04
Filed: 1979-06-21
Abstract: PURPOSE: To prevent the generation of noises of a disc brake by providing a disc brake, wherein the anchored end of a pad is forced against a guide portion, such as an engage groove or guide pin, on the anchored end so that the unstable condition may be avoided.  
     CONSTITUTION: An antirattle spring 11 is constituted such that it can resilientry push the bottom surface of a pad 3 only at a portion thereof biased from a center line a of the pad 3 to the unanchored end thereof. Therefore, the force resiliently pushing up the anchored end of the pad 3 may be decreased, and when the pad 3 becomes in contact with a rotor, the anchored end is pushed down and retained there. Thus, the generation of noises may be avoided due to the unstable support of the pad 3.

Title: Optical waveguide device and displacement measuring instrument using the same
Inventor: SHIONOYA TAKASHI
IPC: G01B11/00
Filed: 1995-03-09
Abstract: PURPOSE: To provide an inexpensive displacement measuring instrument which does not require much optical system adjustment and, at the same time, can be reduced in size. CONSTITUTION: Linearly polarized light of a first direction of polarization from a light source 1 is emitted from the end section having a crest 3 of the area section 2 of an optical waveguide device 100 which becomes the channel waveguide of the polarized light after the light is propagated through the area 2. The emitted light is condensed to a surface 7 to be measured through a 1/4 wave plate 5 and objective lens 6 and reflected light from the surface 7 returns to the crest 3 as linearly polarized light of a second polarizing direction. The returned light is propagated through first, second, and third area sections 2, 24a, and 24b which become slab waveguides against the light and reaches photodetectors 10-13.  When the light reaches the photodetectors 10-13, the distribution of the light varies depending upon the position of the surface 7, because the slopes 8 of the areas 2, 24a, and 24b act as the slopes of prisms.
