Title: Surface hardening treatment of optical transmitter array
Inventor: MISHINA YOSHIHIKO
IPC: G02B6/06
Filed: 1990-03-07
Abstract: PURPOSE:To form a surface hardened protective layer which is free from burrs by holding an optical transmitter array coated with a surface treating agent of a UV curing type on its light entering and exiting end face in the major axis direction, then irradiating the end faces with UV rays after holding the array in a rotating state or while rotating the array, thereby subjecting the surface treating agent to a curing treatment. CONSTITUTION:The surface treating agent of the UV curing type is applied on the light entering and exiting end face of the optical transmitter array 11 formed by joining and crimping the arranging body of distributed index rod-shaped lenses with two sheets of plate members 12. Such optical transmission body array 11 is held in its major axis direction and is irradiated with the UV rays after the array is held in the rotating state or while the array is kept rotated, by which the surface treating agent is subjected to the curing treatment. The surface treating agent essentially composed of polyfunctional acrylate having >=2 pieces of acryloyloxy groups in one molecule is preferably used as the surface treating agent of the UV curing type to be applied. The cured protective film which has a high hardness, has a uniform thickness and is free from the burrs is formed in this way.

CONSTITUTION:A cylinder 2 is formed with an upper cylinder 2' and a bellows 8, and hung from an upper edge of a box body 1 so as to cause a dislocation of thermal displacement to be absorbed. An interval between the cylinder 2 and the box body 1 is made into airtightness and inhaled by a vacuum pump so that it is made to come into an adiabatic state. A low temperature liquid is poured into the cylinder 2 and the level is detected by a detecting sensor 16, thus its quantity is detected. A chute 10 adjusted to a work is airtightly installed in the cylinder so as to pass through the inside of these cylinders 2 and 2', an opening 11 is installed in the upper part, a gasified body out of the low temperature liquid is put in the chute, whereby the work is precooled, thus penetration of the outside air is prevented from entering. With this constitution, consumption of the low temperature liquid is reducible, and since the work is passed through the chute inside of constant temperature distribution at constant time, quality improvement is well promotable.
