Abstract: An oil feeding device includes a tube body formed of metal and having a tube connecting part, and a connection pipe formed of resin and having a pipe connecting end. A press-fitting member and a seal member are clamped between the tube connecting part and the pipe connecting end. The press-fitting member includes a press-fitting body having a cylindrical outer peripheral face, which is fitted to an outer periphery of the tube connecting part, and claws which are formed at one end of the press-fitting body. The pipe connecting end is provided with a reduced diameter part which is formed by annularly reducing a diameter of a part of the pipe connecting end. The reduced diameter part retains the pipe connecting end, in engagement with the claws, by being formed by plastic deformation before or after the pipe connecting end is connected to the tube connecting part.

Abstract: A fuel cap 20 includes a casing 21, a handle 22 mounted on an upper portion of the casing 21 composed of a non-conductive resin material, and grounding mechanism composed of a conductive material. The grounding mechanism includes a contact member 31 that is attached to the handle 22 and is arranged at a position to be in contact with the handle 22 when the handle 22 is held with fingers, and a tether 34 that is linked with the contact member 31 and is used for connection with a fueling lid 12. When the user grasps an operating portion 23a of the handle 22, the user touches arches 31a, 31a of the contact member 31 and the static electricity accumulated in the user is grounded through the tether 34. The fuel cap 20 of this simple structure does not require the high accuracy of dimensions to form the grounding means and attains the sufficient shock resistance.

Abstract: Disclosed is a steel for machine structural use having good machinability and chip-breakability as well as a method of producing the steel. The steel consists essentially of, by wt. %, C: 0.05-0.8%, Si: 0.01-2.0%, Mn: 0.1-3.5%, S: 0.01-0.2%, Al: 0.001-0.020%, Ca: 0.0005-0.02%, O: 0.0005-0.01% and N: 0.001-0.04%, and further, one or both of Ti: 0.002-0.010% and Zr: 0.002-0.025%, the balance being Fe and inevitable impurities. At production of the steel controlled deoxidization is conducted by operation meeting certain conditions so that at least a certain amount of “duplex inclusion” having a specific chemical composition may be formed, and Ti and/or Zr is added to precipitate finely dispersed MnS inclusion particles with nuclei of Ti-oxide and/or Zr-oxide. The finely dispersed MnS inclusions must share a determined part of the total sulfide inclusions.

Abstract: Different heterogeneous databases that are accessible in at least one of the data management method and the data structure. A heterogeneous database manager accepts an access request in a common format, identifies a database management system to be accessed, and accesses the database management system to acquire a database and a data item to generate an access information table. The heterogeneous database manager references the table and generates a access command specific to the database management system to manage, collect, create, and update data desired by the user.
