Abstract: An engine includes a cylinder block including a cylinder wall, a cylinder liner, and a water jacket. The engine further includes a heater including an induction coil disposed in the water jacket. The heater is configured to heat the cylinder wall by generating an eddy current in the cylinder wall by an alternating current flowing through the induction coil.

Abstract: A heat transport fluid includes a base fluid; and solid particles which are dispersed in the base fluid, have an average particle diameter of 200 to 400 nm, and have a potential difference of 35 mV or more from the base fluid, and a heat transport device uses the heat transport fluid.

Abstract: A cable connector includes a housing and a first contact provided in the housing. The first contact includes a first engaging and pivoting unit opposed to a back surface of the cable. The cable connector also includes a second contact which is provided in the housing and which includes a second engaging and pivoting unit opposed to the back surface of the cable. The second engaging and pivoting unit has a root which is thicker than that of the first engaging and pivoting unit. The cable connector also includes a cover. The cover includes a first through hole into which the first engaging and pivoting unit is inserted, a first cam unit engaged with the first engaging and pivoting unit, a second through hole into which the second engaging and pivoting unit is inserted, and a second cam unit engaged with the second engaging and pivoting unit.

Abstract: A connector for a flat terminal includes a lever, a housing and contact. The lever has pivots. The housing is formed with a terminal recess and provided with bearings. The contact has a contact point and is located in the terminal recess. The housing includes guide ribs for separating the base end of the lever from the contact point in the process of attaching the lever to the housing. The contact point is located between the guide ribs. The guide ribs are formed on the bottom of the terminal recess in the housing, and stick out more than the contact point from the bottom of the terminal recess.

Abstract: A thin board-to-board connector with high density in which there is no connection between three-dimensional complex metal springs. The board-to-board connector includes a connector having a bump for electrical connection having an umbrella shape on a board and connected to a circuit board and a connector having an elastic electrically conductive section having a through hole made in a conductive pattern on an elastic insulating board and connected to a circuit board electrically connected to the elastic conductive section. When a bump is inserted into the through hole, the elastic conductive section is electrically connected to the bump, and the side surface of the through hole is pressed against to the bump and elastically deformed and dented. Consequently, the bump is press-fit into the through hole.

Abstract: A cable connector includes a housing, a first contact having a first contact unit opposed to a front surface of a cable and an engaging and pivoting unit opposed to a back surface of the cable, a second contact which is provided in the housing and which has a second contact unit opposed to the front surface of the cable and a wall opposed to the back surface of the cable, and a cover which is turnably supported on the engaging and pivoting unit by a through hole into which the engaging and pivoting unit is inserted and a cam unit engaged with the engaging and pivoting unit. The engaging and pivoting unit is engaged with the cam unit so that the cover can move in an inserting and releasing direction of the cable. The wall limits movement of the cover in an inserting direction of the cable.

Abstract: Plug-socket connector apparatus for optical fiber termination comprises first and second plugs and a socket. The first and second plugs are both single ferrule plugs. The socket is a molded interconnect device and a plug holder, and includes terminals located on the bottom face of the socket, first and second bores located at one side of the socket, and first and second retainers. The retainers retain latches formed in the plugs so as to prevent the plugs from falling out of the bores and to restrict rotation angles of the plugs around the axes within predetermined rotation angle ranges, when the plugs is plugged in the bores.

Abstract: A thin board-to-board connector with high density in which there is no connection between three-dimensional complex metal springs. The board-to-board connector (1) comprises a connector (4) having a bump (43) for electrical connection having an umbrella shape on a board (41) and connected to a circuit board (2) and a connector (5) having an elastic electrically conductive section (54) having a through hole (55) made in a conductive pattern (53) on an elastic insulating board (51) and connected to a circuit board (3) electrically connected to the elastic conductive section (54).
