Title: Connection structure between optical waveguide and optical fiber
Inventor: EBATA MOTOHARU
IPC: G02B6/30
Filed: 1989-04-07
Abstract: PURPOSE:To prevent the optical fiber and optical waveguide from being not aligned with each other and a substrate 13 from breaking by forming an optical waveguide between 1st and 2nd fiber positioning bases and fitting a 2nd substrate has nearly the same coefficient of thermal expansion with a 1st substrate. CONSTITUTION:The 1st and 2nd fiber positioning bases 22 and 23 are formed of glass on the 1st substrate 21 and fiber guide grooves 24 and 25 are formed in the 1st and 2nd fiber positioning bases 22 and 23 perpendicularly to their opposite surfaces. End parts of optical fibers 12 and 15 are fitted in the fiber guide grooves 24 and 25 and the 2nd substrate 13 where the optical waveguide is formed is sandwiched between the 1st and 2nd fiber positioning bases 22 and 23. At this time, both end surfaces of the optical fiber 14 face the end surfaces of the optical fibers 12 and 15 and the 1st substrate 21 and 2nd substrate 13 are nearly equal in coefficient of thermal expansion. Consequently, the connection relation between the optical waveguide and optical fiber never deviates even if the temperature varies. Further, the optical waveguide 14 and optical fiber 15 are aligned with each other automatically, alignment need not be performed, and the productivity is improved.

Title: Carrier for electrophotographic dry type developer
Inventor: UCHIDA MITSURU
IPC: G03G9/10
Filed: 1980-07-02
Abstract: PURPOSE:To facilitate (+) charging of a toner and prevent FP fragments from sticking on the surface of a photoreceptor and forming a thin film by treating the surfaces of carrier particles coated with fluoropolymer (FP) by means of an org. acid having carbon fluoride groups. CONSTITUTION:Carrier particles coated with a (co)polymer such as CF2=CF2 are immersed in a methanol soln. of the org. acid (an aromatic acid of which H of benzene nuclei or the like is substituted by C9H17SO3H, C9H17COOH, C9H17O groups  or the like) having carbon fluoride groups expressed by formulas I, II, after which  they are removed and the solvent is evaporated, whereby the surface treated carrier  is obtained. This carrier can sufficiently charge the toner to (+) with weak agitating of a short time, and prevents the stripping of FP, the sticking thereof on the  surface of a photoreceptor to form a thin film, and the consequent development defect of latent images and the formation of white streaks in copied images. In this  way, more than tens of thousands of copied images are obtained continuously without the above-described drawbacks.
