摘要:
A device connector is provided with a metal reinforcing plate (30) including an opening (31) for permitting the passage of terminal fittings, a housing main body (10), a flange (11) formed by insert molding using the reinforcing plate (30) and synthetic resin, a device-side housing portion (12) to be accommodated into a connector mounting hole, and terminal fittings (15) held in the housing main body (10) while being passed through the opening (31). The reinforcing plate (30) is beveled along a peripheral edge thereof to form an R-surface (36). Thus, the device connector is produced at a low cost and eliminates possible starting points of cracks created in the synthetic resin covering the peripheral edge of the metal reinforcing plate (30).

摘要:
Polynuclear dicarboxylatotetrachromium (III) complexes are produced by reacting a dicarboxylic acid with a monobasic chromic (III) salt in a proportion of 4 moles of monobasic chromic (III) salt to 1 mole of dicarboxylic acid. Surface treating agents comprising these complexes provide a surface with desirable properties such as durable water repellency, adhesiveness, antistatic properties, etc.
