Abstract: A sliding member including a coating film in a sliding surface on a base material. The coating film includes, when a cross section thereof is observed by a bright-field TEM image, a laminated part configured by laminating, in a thickness direction, repeating units including black hard carbon layers and white hard carbon layers and a surface layer part composed of a white hard carbon layer provided on the laminated part. A Vickers hardness of the black hard carbon layer is within a range of 700 to 1600 HV, a Vickers hardness of the white hard carbon layer is higher than a Vickers hardness of the black hard carbon layer adjacent thereto and within a range of 1200 to 2200 HV, and a Vickers hardness of the surface layer part is lower than the Vickers hardness of the white hard carbon layer and within a range of 800 to 1200 HV.

Abstract: A vehicular shock absorber to be mounted on a vehicular exterior side with respect to a vehicular interior component includes a low rigidity portion, a high rigidity portion having higher rigidity than the low rigidity portion, and a first connection portion. The low rigidity portion includes a first plate portion that has a first vehicular interior side surface, and a first mount portion that extends from the first vehicular interior side surface and is to be fixed to the vehicular interior component. The high rigidity portion includes a second plate portion that has a second vehicular interior side surface, and a second mount portion that extends from the second vehicular interior side surface and is to be fixed to the vehicular interior component. The first connection portion extends between and connects the first plate portion of the low rigidity portion and the second plate portion of the high rigidity portion.

Abstract: To provide a sliding member comprising a coating film exhibiting constant and stable chipping resistance and wear resistance and excellent in peeling resistance (adhesion), and the coating film thereof. The above-described problem is solved by a sliding member (10) comprising a coating film (1) on a sliding surface (16) on a base material (11). The coating film (1) has, when a cross section thereof is observed by a bright-field TEM image, a total thickness within a range of 1 ?m to 50 ?m, in repeating units including black hard carbon layers (B), relatively shown in black, and white hard carbon layers (W), relatively shown in white, and laminated in a thickness direction (Y). In the black hard carbon layer (B) and the white hard carbon layer (W) adjacent to each other, the white hard carbon layer (W) has higher hardness and a larger [sp2/(sp2+sp3)] ratio than the black hard carbon layer (B).

Abstract: To enable improvement of efficiency in various settlement operations and cost reduction by linking business-to-business transactions with bank transactions. A computer 100 configured to mediate e-commerce transactions between companies executes processing of receiving invoice data addressed to a buyer from a supplier terminal 200, storing the received invoice data in a storage device 101, and transmitting the invoice data to a buyer terminal 300 in response to an acquisition request from the buyer terminal 300. The buyer terminal 300 executes processing of receiving the invoice data from the computer 100, generating payment schedule data by attaching settlement information to the invoice data, and transmitting the generated payment schedule data to the computer 100.

Abstract: A coupler includes a first connector and a second connector. The first connector includes a first connector main body and the first connector valve member. The second connector includes a second connector main body and a second connector valve member. A part of the first connector valve member is to be inserted in an insertion portion of the second connector and a seal between an outer circumference of the first connector valve member and an inner circumference of insertion portion of the second connector is formed by a seal on the first connector valve member. An axial length from a leading end of the second connector main body to a leading end of the second connector valve member is larger than an axial length from a leading end of the first connector valve member to the seal.
