Abstract: A connector of the invention includes a main body; a terminal, arranged at the main body, to be electrically connected with a connection object having at least one uneven part; and an auxiliary member mounted on the main body and having at least one fitting part to fit to the respective of the at least one uneven part of the connection object. According to the invention, when the uneven part varies in location and/or configuration in accordance with the types of the connection objects used, only the connection object having the uneven part corresponding in location and/or configuration to the fitting part formed in the auxiliary member can be loaded onto the connector to prevent erroneous loading of the connection object.

Abstract: The present invention relates to Friend murine leukemia virus (F-MuLV) specific monoclonal antibodies, or binding fragments thereof, specific for an antigenic determinant of a gp85 envelope precursor protein characteristic of a methanol-fixed F-MuLV infected cell. The invention also relates to hybridomas resulting from the fusion of myeloma cells and spleen cells, which hybridomas produce a Friend murine leukemia virus (F-MuLV) specific monoclonal antibody specific for an antigenic determinant of a gp85 envelope precursor protein characteristic of a methanol-fixed F-MuLV infected cell. The invention further relates to kits containing the above-described monoclonal antibodies.

Abstract: An electronic module of the invention is so structured that a plurality of first electronic components are mounted on a top surface of a card-like substrate; a first radiating board is commonly stuck to two or more top surfaces of the first electronic components; a plurality of second electronic components are mounted on a bottom surface of the substrate; and a second radiating board is commonly stuck to two or more bottom surfaces of the second electronic components. The heat generated by high-speed operation of the first and second electronic components is radiated to outside air through the first and second radiating boards.

Abstract: A connector for module that connects a module to a printed circuit board in a position wherein the board plane of the module is approximately parallel to the printed circuit board.

Abstract: A connector module to be connected to an integrated circuit device having rear electrodes provided on a back surface thereof facing away from a wiring board. The connector module includes: a connector having contacts to be electrically connected to the rear electrodes; and a fixture structure for fixing the connector to the integrated circuit device.

Abstract: A connector for module that connects a module to a printed circuit board in a position wherein the board plane of the module is approximately parallel to the printed circuit board.

Abstract: A cap that is to be fitted to a printed circuit board, which has a conductive pad on the front side of the rectangular board thereof and which is to be connected to the connector. The cap is formed into a bag and is shaped into a wedge that gets thinner towards the front, and the cap has a window for exposing the conductive pad of the printed circuit board.

Abstract: A method of oblique spherical polishing of an optical connector by which a desired contact surface angle on an axis of the optical connector is obtained easily and securely without requiring additional processing. In order to form a dome of a radius R, which is oblique with the contact surface angle .theta.', at the end surface of the optical connector 20, which has ferrule 22 of which a tip 24 is beveled, the tip of the optical connector 20 is polished by tilting it with the angle .theta. which fulfills the relationsin .theta.=sin .theta.'+S/Rwhere S is the amount of the deviation of the dome.
