TLDR
In this paper, a cylindrical casing with some boss, infrared cut-off filter, CMOS imaging sensor and CMOS driving circuit board installed successively inside the casing was used for photo-electronic image conversion.Abstract:
THe photoelectronic image converting method is that through coincidence of the photosensitive surface of CMOS imaging sensor with the imaging surface of the microscope objective, optical image is converted directly into electric image signals The device includes a cylindrical casing with some boss, infrared cut-off filter, CMOS imaging sensor and CMOS driving circuit board installed successivelyfrom bottom to top inside the casing When it is used, the device in inserted into the eye lens barrel of optical microscope With simple structure and low cost, the present invention realizes high quality photoelectronic image conversion without needing any relay optical systemread more

Polymer article and its use for controlled introduction of reagent into a fluid
TL;DR: A solid polymeric body comprising a polymer matrix containing a water-soluble reagent leachable into a fluid containing condensed water, said matrix being reagent being permeative and insoluble in the fluid, and the said body preferably having a softening point substantially above that of the temperature of the fluid environment in which it is to be employed is useful for the introduction of an additive reagent into said fluid particularly when said fluid is located in a subterranean formation.
