Abstract: PROBLEM TO BE SOLVED: To reduce cost and to improve workability and reliability by forming a sleeve having the function of a collimator lens at one edge part in an optical axial direction and the function of a condenser lens at the other edge part so that the apparent shape can be almost like a bale for realizing optical connection with an optical fiber and a light emitting and receiving module. SOLUTION: A sleeve 21 is formed of synthetic resin materials with high light transmissivity so as to be shaped almost like a bale as a single object. In this case, an almost semi-spherically formed lens part 23 having the function of a collimator lens is formed at one edge part of an optical axial direction in parallel with the extended direction of a cylindrical sleeve main body 22, and an almost semi-spherically formed lens part 24 having the function of a condenser lens with the same curvature radius as that of the curved surface of the lens part 23 is formed at the other edge part. Then, the lens parts 23 and 24 are integrally formed so as to be protruded to the outside. This sleeve 21 is constituted so that optical connection can be realized in an optical connector at the time of interfitting a light plug constituting the optical connector into a receptacle.

Title: Magnetic separator
Inventor: MORITA MINORU
IPC: B01D35/06
Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To contrive prolonging operation time until a magnetic filter is clogged and becomes in a state in which back washing is needed by installing an inflow position control means for stepwise or continuously, and selectively changing the adsorptive position of magnetic material to be removed to a magnetic filter matrix to an arbitrary position. SOLUTION: Water to be treated introduced into a vessel 1 from an inflow line 4 by opening a valve 5 flows in a magnetic filter matrix 3. At this time, magnetic flocs in the water to be treated are caught and recovered, and treated water is caused to flow out from an outflow line 6. When flowing of the water to be treated is continued, the density of magnetic flocs at about the same height as that of an inflow port for the water to be treated is increased to cause clogging.  This clogging is judged in the light of detection of a difference between pressures measured by pressure gauges 14, 15, and when the pressure differential attains a prescribed value, the magnetic filter matrix 3 is pulled down until a place in which the magnetic flocs are not adsorbed becomes at a height of the inflow line 4 by a driving mechanism 13 through a driving shaft 12, and the above operation is continued again.
