摘要:
A method of analyzing a sample solution containing an ionic species of interest paired with an ionic species of the opposite sign comprises introducing the sample solution into a separation column with an eluant solution, introducing an eluate from the separation column into the inner passage of a diffusion type deionizer of the double tubular construction which is defined by a tube of an ion exchange composition, while a scavenger solution is introduced into the outer passage of the deionizer in a direction of flow opposite to that of the eluate in the inner passage, whereby the ionic species of the opposite sign is removed from the eluate into the scavenger solution, and measuring the electric conductivity of the eluate from the deionizer to thereby determine the concentration of the ionic species of interest in the sample solution. An apparatus for carrying out this method is also disclosed.

A card adapter mounted on a card connector in a state where a card is held is provided. The card adapter includes an adapter body guided by a guide member which guides a separate card different from the card when being mounted to the card connector, and mounted on the card connector so as not to come into contact with contact terminals for the separate card; and a holding portion making the card held by the adapter body in a state where a rear end of the card is made to protrude from a rear end of the adapter body. The holding portion includes an ejection mechanism ejected by once pressing the card held by the adapter body toward the deep side.

A connector for a card includes first contact terminals that come in contact with first outer connection parts of a card to be fitted, and second contact terminals that come in contact with second outer connection parts of the card. Contact parts of the first contact terminals that come in contact with the first outer connection parts, and contact parts of the second contact terminals that come in contact with the second outer connection parts are formed to face directions orthogonal to each other.

A support structure for a pedal of a vehicle pivotablly supports a pedal assembly (34) to a pedal bracket (38) mounted on a vehicle dash panel (6). The support structure for a pedal of a vehicle includes a reinforce member (14) for the vehicle body; an upper pedal member (44, 46); a lower pedal member (48) having a pedal (48c) at its lower end; an abutting member (50) not coming into contact with the reinforce member when the vehicle is in a normal operation, while it abuts against the reinforce member at its abutting portion (50g) by moving in the rearward direction of the vehicle body when the vehicle crashes; and a connecting mechanism (60) for connecting the abutting member to the lower pedal member in such a manner that relative movement with respect to each other is prevented when the vehicle is in a normal operation, while the connecting mechanism forcibly displaces the lower portion (48b) of the lower pedal member, which is the part locating below the pivot shaft of the lower pedal member, in a forward direction with respect to the upper pedal member when the vehicle crashes.
