摘要:
An object of the invention is to provide a method for removing foreign matter from a glass substrate surface to be finish-processed by a method accompanied with beam irradiation or laser light irradiation on the glass substrate surface. The present invention relates to a method for removing foreign matter from a glass substrate surface, which includes subjecting the glass substrate surface to gas cluster ion beam etching at an accelerating voltage of from 5 to 15 keV.

摘要:
A terminal (20) has a terminal main body (51) with a projection (55) to be engaged with a retainer (40). A wire barrel (21) to be crimped to a core (11) of a wire (10), an insulation barrel (23) to be crimped to an insulating coating (12) and a rubber plug barrel (24) to be crimped to a rubber plug (15) are successively arranged behind the main body (51). Bottom parts of the wire barrel (21) and the insulation barrel (23) are at low positions having substantially the same height. A front end of the wire barrel (23) is crimped flat to suppress bend-up of the core (11). The front end of the crimped wire barrel (21) is insertable to a position facing a projecting end of the retainer (40) when the terminal (20) is inserted to a proper position in a cavity (31) of a housing (30).

A terminal fitting (10, 130, 510) has a connecting portion (11, 131, 511) to be connected with a mating connecting portion, and a crimping portion (12, 140) continuous with the rear end of the connecting portion (11, 131, 511) and including a bottom plate (21, 148, 515) and crimping pieces (22, 147, 516) standing up from the bottom plate (21, 148, 515). The crimping portion (12, 140) is crimped into connection with a wire (30, 120, 590) while surrounding an end portion of the wire (30, 120, 590) by the bottom plate (21, 148, 515) and the crimping pieces (22, 147, 516). The bottom plate (21, 148, 515) is formed with a reinforcing rib (24, 150, 250, 350, 450, 525) extending in forward and backward directions.
摘要:
Locking lances (12) are formed at an outer wall (10B) of a housing (10) and are resiliently deformable between engaging positions to engage terminals (20) and disengaging positions outward from the engaging positions to permit the insertion and withdrawal of the terminals (20). Leading end surfaces (12B) of the locking lances (12) are inclined to project gradually forward toward an inner side of the housing (10). A facing surface (15A) of the outer wall (10B) of the housing 10 facing the leading end surfaces (12B) of the locking lances 12 is inclined to project gradually toward the locking lances (12) at more outward positions on the housing (10). The leading end surfaces (12B) of the locking lances (12) contact the facing surface (15A) when the locking lances (12) are deformed outward beyond the disengaging positions.

摘要:
A joint connector (10) has sub-housings (S) (S1 to S6) that can be built up in plural levels. Projecting pieces (31) project on outer sides of the respective sub-housings (S) in directions intersecting a build-up direction (BUD) of the sub-housings (S) and define hand-push portions (13) by building up the sub-housings (S). The sub-housings (S) built up in levels are fit into the intermediate connector (20) by pushing the hand-push portions (13) towards the intermediate connector (20) so that terminal fittings (40) in the joint connector (10) are connected electrically with intermediate terminals (24) in the intermediate connector (20). Identifying projections (A) on the lower mating surfaces of the projecting pieces (31) enter identifying recesses (B) in the upper mating surfaces of adjacent projecting pieces (31) if the sub-housings (S) are built up properly.
摘要:
A circuit board connector has metal fixing portions (60) for fixing a synthetic resin housing (10) to a circuit board (K). The fixing portions (60) are mounted into the housing (10) and are soldered to the circuit board (K). The housing (10) has mounting grooves (15) for receiving the fixing portions (60), whereas the fixing portions (60) have retaining portions (67) for biting in edges of the mounting grooves (15) to prevent the fixing portions (60) from coming out of the mounting grooves (15). Contact positions of the retaining portions (67) and edges of the mounting grooves (15) are lower than half the maximum height (L1) of the housing (10) for keeping the fixing portions (60) solder-connected with the circuit board (K) against a separating force on the fixing portions (60) in a direction away from the circuit board (K) as the housing (10) thermally expands.
摘要:
Fixing members (30) fixable to a circuit board (K) by soldering are mounted in a housing (10). Each fixing member (30) is comprised of a main panel (31) and a solder leg (32) projecting sideways from the bottom end of the main portion (31). The solder leg (32) has solder entering holes (37) that open at a side of the solder leg (32) toward the circuit board K and at a side opposite therefrom. Each solder entering hole (37) has a cross-section that gradually increases toward both upper and lower open ends (37a, 37b). A locking portion (38) is formed on each solder entering hole (37) and bulges more inward than both open ends (37a, 37b). The locking portion (38) locks solder (H) that enters the solder entering hole (37).
