摘要:
It is an object of the present invention to make it easy to diffuse phosphorus into a silicon film and allow the phosphorus diffusion concentration to be easily controlled by varying the timing at which the dopant gas is allowed to flow. A silicon wafer 10 on whose surface an amorphous silicon film 12 has been formed is placed in a diffusion furnace. After this, phosphine (PH3) or a mixed gas containing phosphine is allowed to begin flowing over the wafer 15 and the phosphorus is diffused into the silicon film 12 before the amorphous silicon film 12 crystallizes and changes into a polysilicon film.

In a method of manufacturing a semiconductor integrated circuit device in which a lower electrode of a capacitor is composed of a polycrystalline silicon film having a surface area increased by surface roughening, an impurity is introduced into the polycrystalline silicon film by vapor phase diffusion in order to reduce the resistance of the lower electrode.

A connector which, when two contacts contact a connection object at positions different from each other in the insertion/extraction direction of the connection object, suppresses deflection of the connection object without increasing a pressing member size. The connector configured so, when the pressing member is rotated to a closed position, a pressing plate is brought into surface contact with the other thickness direction surface of a flexible circuit while pressed by a pressing member pressing portion, and a range including the contact positions between the flexible circuit and first and second contacts is pressed from the side of the other thickness direction surface of the flexible circuit via the pressing plate, so one thickness direction surface of the flexible circuit is brought into press-contact with the first and second contacts. Deflection of the flexible circuit is suppressed by the pressing plate, and the pressing member size need not be increased.

To provide a connector with which a terminal can be easily connected to a substrate without soldering. A connector (10) is configured such that a contact portion (13b) formed at a terminal (13) so as to be elastically deformable in the vertical direction is brought into contact with the upper surface of an LED substrate (3) and is thereby made conductive with the LED substrate (3), and such that a locking portion (14c) of each of locking members (14) is locked to the lower surface of a mounting substrate (4), and thereby the contact portion (13b) of the terminal (13) is held in a state of being in press-contact with the upper surface of the LED substrate (3). Thereby, the terminal (13) can be easily connected to the LED substrate (3) without soldering, and hence the mounting work of the connector (10) can be performed very easily.

A stationary pulley (66) includes a pressing pulley (68) having a stationary pulley surface (66a) and also includes a support pulley (70) having a rotating shaft (15) fixed to the center section of the support pulley. The support pulley (70) is placed so as to face a movable pulley surface (14a) across the pressing pulley (68) in the direction of the axis of the rotating shaft (15), and the support pulley (70) supports an outer peripheral section (68b) of the pressing pulley (68) so as to restrain axial movement of the outer peripheral section (68b). The pressing pulley (68) has an inner peripheral section (68c) axially movable relative to the rotating shaft (15) and can transmit torque to the rotating shaft (15).

A coil component that can be mounted on a printed circuit board, with a part in an aperture of the printed circuit board. The coil component includes a first flange on an upper side and a second flange. Terminal boards are on respective opposite sides of the first flange. Terminals respectively project in a direction perpendicular to an axial direction of a winding drum, from the terminal boards and bend and are inserted into through-holes of the printed circuit board. First and second touching surfaces, which are parts of a downside surface of the second flange, touch an upside surface of the printed circuit board.

The invention is directed to an arrangement for sealing a clearance between a cylinder head and a cylinder block of an engine with a metal gasket clamped therebetween. The metal gasket is formed of a metallic base plate which has a plurarity of openings and beads formed therearound. The base plate may include annular shims welded on the base plate around the openings and a resilient sealing member deposited on the base plate surrounding the openings. The gasket may be disposed in such a manner as to place tip ends of the beads toward the cylinder block which causes a smaller displacement relative to the beads in comparison with the cylinder head. The resilient sealing member may be arranged to have a section of different dimension between a portion located at a side facing the beads and other portion at the opposite side thereof, or between a portion located at a junction where two of the beads meet and other portion.
