Abstract: PURPOSE: To produce the titled castings by sticking ceramics powders on the surface of a three dimensional network structural body consisting of a lost-foam material, sintering it, losing the lost-foam material, subjecting metallic plating on the remaining three dimensional network structural body and thereafter casting the molten metal into the network body.  
     CONSTITUTION: The synthetic resin such as ester polyurethane, etc., is foamed to form the three dimensional network structural body and the ceramics powders of cordierite, alumina, etc., are converted to slurry. Said slurry is impregnated and stuck on the surface of the skelton of the foamed body, is dried and thereafter sintered, by which the porous body 22 consisting of the three dimensional network structural body by the ceramic material 3 and the resin foamed body is simultaneously lost in a high temp. The plating layer 35 such as Ni, Cr, etc., is formed on the surface of the skelton 34 of said ceramic porous body 22 by electroless plating and the porous body 32 is thereafter charged to the casting cavity 20 of a mold 10. The molten metal 26 of cast iron, cast steel, etc., is cast into the cavity from a pouring gate 30, by which the fluid permeable castings having continuous pores 36 are produced.

Title: Structure for locking plug-in optical connector
Inventor: NOMOTO MAMORU
IPC: G02B6/38
Filed: 1987-06-26
Abstract: PURPOSE:To improve the workability of insertion and removal and to enable the low-loss and stable connection of optical connectors to be mounted on a printed circuit board by providing locking structures which allow mechanical locking and unlocking by the insertion and removal of the printed circuit board mounted with the optical connectors without using friction to each optical connector to be fitted. CONSTITUTION:Projections 7 and projections 10 fit to each other on the perpendicular plane in a fitted state and the fitting between both is not released even if the force in the direction of removing the connectors act between a housing 2b and an arm 9. Only the housing 2a is first retreated together with the printed circuit board 1 and the projections 11 push up the projections 8 when the print circuit board 1 is successively removed. The projections 7 integrated with the projections 8 are, therefore, simultaneously force-expanded as well and the projections 7 are disengaged from 10 and the housing 2b and the arm 9 are unlocked. The end faces of the projections 5 of the housing 2b abut against the end faces of the grooves 6 of 2a and 2b is removed from the housing of the unit side connector when the removal progresses further. The optical connectors mounted on the printed circuit board are thus stably connected at the low loss without deteriorating the insertion and removal workability of the printed circuit board.
