Title: Curved optical wave guide
Inventor: WATANABE KAZUAKI
IPC: G02B6/122
Filed: 1989-03-27
Abstract: PURPOSE:To obtain the curved optical wave guide layer having high propagation ratio by successively, selectively and epitaxially growing a II-VI compd. semiconductor having a smaller refractive index as a clad layer and the same compd. having a larger refractive index as the optical wave guide layer on a substrate, and then forming a 45 deg. mirror. CONSTITUTION:An SiO2 film 15 is deposited on the GaAs substrate 11 by a thermal CVD method and after the SiO2 15 on the part to be formed with the light guide is removed by photolithography, the lower clad layer 12, the optical wave guide layer 13 and the upper clad layer 14 are successively epitaxially grown with the residual SiO2 film 15 as a mask. The optical wave guide layer 13 consisting of ZnSe is selectively grown on the (100) face of the GaAs substrate at this time, then the growth speed of the (100) face and (111) face is larger than the growth speed of the other crystal faces and, therefore, the (100) face to constitute a specular face is 45 deg. with the optical wave guide extending in the (110) direction and perpendicular to the (100) face of the substrate surface. The critical angle of the internal reflection at the ZnSe/air boundary is 25.3 deg. and, therefore, the incident light on the mirror at 45 deg. incident angle does not transmit the specular surface. The light is confined in the optical wave guide in this way and is curvilinearly propagated.

Abstract: PURPOSE:To prevent dislocation of a tape by driving one reel in the take-up direction for a given period of time from the commencement of loading, braking the other reel and driving afterward both reels in the take-up direction until the loading is completed. CONSTITUTION:A reel motor for rotatively driving a supply side reel 12 and a reel motor for rotatively driving a take-up reel 14 are equipped, and one reel motor for either of the reels is electrified in the tape take-up rotating direction for a given period of time from the commencement of loading, while the other reel is braked, and after the lapse of the above period of time, both reel motors are electrified in the tape take-up direction until the loading is completed. By this method, the tape 74 can be prevented from being wound around one reel at the time of commencing the loading, and hence no dislocation of the tape 74 will take place.

Title: Preventive device for over-adjustment of clearance of brake shoe
Inventor: MITSUOKA NAOCHIKA
IPC: F16D65/56
Filed: 1980-06-04
Abstract: PURPOSE: To prevent over-adjustment due to the elastic deformation of elements constituting the brakes by forming the preventive device so that the rotation of an adjusting lever after the clearances of the shoes disappear is prevented.  
     CONSTITUTION: When a parking lever 16 is turned strongly in order to obtain powerful braking force, mighty expanding force works to the shoes even after the shoes slide and contact to a drum, and the axial force of a strut 12 increases remarkably with the functioning. Accordingly, the rotational resistance of a washer 30 is increased, the rotational resistance of the adjusting lever 17 is augmented with the increase and rotation is prevented. Even when the strut 12 is further moved, the adjusting lever 17 does not move, a spring 26 is contracted and the movement of a strut 10 is absorbed. Thus, over-adjustment is not conducted because a tooth feeding section 22 of the lever 17 does not engage with an engaging section 14 and a star wheel 15 is not turned.

The prepared composition prevents effectively formation of rhyparia and is effective as preventive for dental caries, gingivitis, and pyorrhea alveolaris. It can be formed by pharmaceutical manufacturing into toothpaste, oral cavity cleaner, etc. for use.
