Abstract: An intraocular lens selection apparatus and an intraocular lens selection method for selecting an intraocular lens to be implanted into an examinee's eye. The apparatus has an input unit which inputs corneal wavefront aberration of the eye, a memory which stores wavefront aberrations of a plurality of intraocular lens models, an unit which sets, as a target value, desired post-operative residual wavefront aberration of the eye after the lens is implanted, an unit which calculates, as an estimated value, post-operative residual wavefront aberration of the eye to be obtained when each lens model is implanted, based on the inputted corneal wavefront aberration and the stored wavefront aberration of each lens model, and specifies one of the lens models which renders the estimated value close to the set target value, a monitor, and a display control unit which controls the monitor to display information of the specified lens model.

Abstract: A connector (10) for a substrate has a tubular hood (21) in which at least one mating housing can be fit. The hood (21) is mounted on a surface of a circuit substrate (90). Channels (45, 46) are formed in a bottom wall (22) of the hood (21) and define grooves opening into the hood (21) for preventing the mating housings from being fitted in wrong fit-in concavities (28) of the hood (21). The channels (45, 46) have flat bottom surfaces that contact and extend along the circuit substrate (90) for stably supporting the hood (10) while spacing the bottom wall (22) from the circuit substrate (90).

Abstract: A male housing (60) includes a receptacle (61) in which male tabs project. A female housing (10) includes a tower (11) with cavities (14) for accommodating terminal fittings. A front holder (13) is mountable on the tower (11) and has a front wall (31). A surrounding wall (32) projects from a peripheral edge of the front wall (31) for covering the outer peripheral surface of the tower (11). A receptacle (61) is fit on the tower (11) with the front holder (13) thereon. Inner projections (43) are provided on the inner peripheral surface of the surrounding wall (32) and project towards the outer peripheral surface of the tower (11) and outer projections (45) are provided on the outer peripheral surface of the surrounding wall (32) and project towards the inner peripheral surface of the receptacle (61).

Abstract: A prevention part projected forward from a rear-end surface of a hood part (12) has a first prevention piece (61) disposed within a region of a rear-end surface of the hood part (12) from which a plurality of tabs (22) is projected; and a pair of second prevention pieces (62) so disposed as to sandwich the first prevention piece (61) therebetween, with the second prevention pieces (62) and the first prevention piece (61) arranged in a row at certain intervals. The tabs (22) are disposed between the first prevention piece (61) and the second prevention pieces (62). This construction is capable of decreasing a tab-disposing region.

Abstract: A wire cover (60) is mounted on a rear part of a housing main body (21) to cover wires (50) drawn out from the rear surface of the housing main body (21). Cover locks (72) are provided on side walls (62) of the wire cover (60), and cover engaging portions (33) are provided on side surfaces of the housing main body (21). The cover locks (72) and the cover engaging portions (33) resiliently engage each other as the side walls (62) are resiliently deformed to hold the wire cover (60) on the housing main body (21). Detachment preventing pieces (76) are provided in parallel with the cover locks (72) on the side walls (62). The detachment preventing pieces (76) are accommodated in the receptacle when the housings (10, 20) are connected properly.

Abstract: A connector includes female and male housings (10, 40) that are connectable along a connecting direction (CD). A connection detector (30) is mounted on the female housing (10) for movement along the connecting direction (CD) between standby and detection positions. The connection detector (30) does not contact receiving portions (48) of the male housing (40) when the connection detector (30) is at the standby position. However, pressing portions (32) of the connection detector (30) press the receiving portions (48) when the connection detector (CD) is at the detection position to prevent relative movements of the connection detector (30) and the male connector housing (40). Thus, connection resistance between the receiving portions (48) and the pressing portions (32) is not produced when the connection detector (30) is at the standby position.

Abstract: A male terminal fitting (20A) is inserted into a cavity (11) in a housing (10) from the rear, and has a tab (26A) that passes through an open portion (16) of a front wall (14) of the cavity (11). A proximal portion (27A) of the tab (26A) is sandwiched in a thickness direction between an inner surface of the open portion (16) and a front closure (30) mounted on the open portion (16). The thickness of the proximal portion (27A) of the tab (26A) of the terminal fitting (20A) is less than that of a connection portion (28A) of the tab (26A). Therefore the connection portion (28A) of the tab (26A) can have a thickness different from a predetermined thickness, provided that the proximal portion (27A) of the tab (26A) has the predetermined thickness.

Abstract: A connector has a male housing (10) with a hood (12) and a female housing (20) that can be telescoped into the hood (12). The female housing (20) has an elastic hold-down piece (38) that elastically contacts the male housing (10) at an angle to a direction in which the housings (10; 20) are telescoped together. An elastic pressing force of the elastic hold-down piece (38) prevents housings (10) and (20) from shaking at an angle to the fit-in direction. The elastic hold-down piece (38) is made of the synthetic resin and has a small elastic deformation amount. Thus, the elastic hold-down piece (38) has a higher effect than an elastic hold-down piece made of rubber in preventing shaking.

Abstract: A connector has a front retainer (30) that can be held at a partial or full locking position, engaging portions (38) formed on outer surfaces of locking arms (36) are engaged with partial locks (15) or full locks (16). Thus, even if resilient deforming portions (37) of the locking arms (36) are deformed to widen the spacing therebetween due to a thermal shrinkage at the time of resin-molding, areas of engagement of the engaging portions (38) and the partial locks (15) and those of the engaging portions (38) and the full locks (16) are not reduced. Further, engaged parts of the engaging portions (38) and the partial or full locks (15, 16) are in insertion spaces (14), and the front retainer (30) will not be unlocked by interference of external matter.

Abstract: A connector includes female and male housings (10, 40) that are connectable along a connecting direction (CD). A connection detector (30) is mounted on the female housing (10) for movement along the connecting direction (CD) between standby and detection positions. The connection detector (30) does not contact receiving portions (48) of the male housing (40) when the connection detector (30) is at the standby position. However, pressing portions (32) of the connection detector (30) press the receiving portions (48) when the connection detector (CD) is at the detection position to prevent relative movements of the connection detector (30) and the male connector housing (40). Thus, connection resistance between the receiving portions (48) and the pressing portions (32) is not produced when the connection detector (30) is at the standby position.

Abstract: A male terminal fitting (20A) is inserted into a cavity (11) in a housing (10) from the rear, and has a tab (26A) that passes through an open portion (16) of a front wall (14) of the cavity (11). A proximal portion (27A) of the tab (26A) is sandwiched in a thickness direction between an inner surface of the open portion (16) and a front closure (30) mounted on the open portion (16). The thickness of the proximal portion (27A) of the tab (26A) of the terminal fitting (20A) is less than that of a connection portion (28A) of the tab (26A). Therefore the connection portion (28A) of the tab (26A) can have a thickness different from a predetermined thickness, provided that the proximal portion (27A) of the tab (26A) has the predetermined thickness.
