An antenna coil includes an air-core coil wound helically in a plane and a plate magnetic core member inserted in the air-core coil to be approximately parallel with a plane of the air-core coil. The magnetic core member is formed by a soft magnetic metal, an amorphous or ferrite, or a composite member of a powder, flake and plastic, or rubber. The magnetic core member is formed by performing an injection molding operation or a compressing molding operation of the composite member. Alternatively, the magnetic core member is a magnetic coating formed by applying and drying the composite member. A non-magnetic conductive plate that has a conductivity is layered on a surface of the air-core coil through which the magnetic core member is inserted. The conductive plate is made of a copper, a copper alloy, an aluminum or an aluminum alloy having 0.01 to 2 mm thickness. The antenna coil is operated by relatively high frequency while it is rigid relatively.

A high-performance and low-cost image-forming optical system has a reduced number of constituent optical elements and is made extremely thin, particularly in a direction perpendicular to an image pickup device, by folding an optical path using only three reflecting surfaces. The image-forming optical system has a front unit including a first prism 10, an aperture stop 2, and a rear unit including a second prism 20. The first prism 10 has a first transmitting surface 11, a first reflecting surface 12, and a second transmitting surface 13. The second prism 20 has a first transmitting surface 21, a first reflecting surface 22, a second reflecting surface 23, and a second transmitting surface 24. An optical path incident on the first reflecting surface 22 and an optical path exiting from the second reflecting surface 23 intersect each other. The first reflecting surface 12 of the first prism 10 and the first and second reflecting surfaces 22 and 23 of the second prism 20 have a curved surface configuration that gives a power to a light beam. The curved surface configuration is a rotationally asymmetric surface configuration that corrects aberrations due to decentration.

An electro-optical device is provided which includes an electro-optical panel; and a metal frame configured to accommodate the electro-optical panel therein. The metal frame includes a plurality of side walls and corner portions provided between the side walls. A distal end of at least a portion of at least one of the side walls has a folding portion having a structure that inner surfaces are opposed to each other. At least one of the corner portions adjacent to the side wall having the folding portion has a seamless curved shape.

The present invention provides a radiator for a light emitting unit, annexed to the light emitting unit including a multiplicity of light emitting diodes mounted on substantially the same axis line on a first principal surface of a wiring substrate. The radiator includes a radiating plate and a heat pipe. The radiating plate is combined with the wiring substrate, with a first principal surface faced as a faying surface to a second principal surface opposite to the first principal surface of the wiring substrate, and is provided with a heat pipe fitting portion. The heat pipe is mounted into the heat pipe fitting portion of the radiating plate while keeping close contact with the inner wall of the heat pipe fitting portion. The heat generated from the light emitting diode group is transferred to a radiating means through the radiating plate and the heat pipe.

An outer casing of a non-aqueous electrolyte battery is capable of being mass-produced as well as thin and resistant to damage. The outer casing 4 comprises a casing body 4a and a cover 4b. After being internally packaged, a non-aqueous electrolyte battery 2, e.g. a lithium-ion polymer secondary battery, is sandwiched between the casing body 4a and the cover 4b, which are then joined together integrally. The cover 4b is formed from a film-shaped sheet material 4c of a synthetic resin to make the outer casing 4 thin. The casing body 4a and the cover 4b have a casing body outer peripheral frame 9 and a cover outer peripheral frame 10, respectively, formed by injection molding. Joint portions of the casing body 4a and the cover 4b have stepped portions 9a and 10a, respectively. The stepped portions ensure the mechanical strength against shock and impact. With this structure, the outer casing 4 is resistant to damage.

A golf club head that includes: a pedestal composed of at least two ribs each having convex portions at both ends and formed on an inner face of the head; a metal weight disposed on the ribs; and a weld bead extending on a surface of the weight between the convex portions, the weight being fixed on the inner face of the head by the weld bead.

Provided is a planar lighting device having a thin shape and capable of emitting uniform illumination light with less brightness unevenness. The planar lighting device includes a first and a second light sources arranged at a given distance apart from each other and a light guide plate arranged between the first and second light sources. The light guide plate includes a light exit plane, a first light entrance plane facing the first light source and containing one side of the light exit plane, and a second light entrance plane facing the second light source and containing the opposite side to the one side, and has a shape growing thicker from the first and second light entrance planes toward the center. The light guide plate contains scattering particles for scattering light entering through the first and second light entrance planes and propagating inside by a ratio satisfying 1.1≦Φ·Np·LG·KC≦8.2.

A slide switch having a reduced number of parts and formed thin. The slide switch includes a case having first electrode pairs and a second electrode pair arranged in a bottom thereof, a slide member slidably mounted in the case, and a biasing member for biasing the slide member. The biasing member has projections formed on one surface of a floor thereof, and each having a back wall portion, and a first electric conductor disposed opposite the back wall portion. When the slide member is operated in the direction of one of the projections against a biasing force, the projection is elastically deformed whereby the electrodes of the first electrode pair become conductive through the first electric conductor. When the slide member in a neutral position is pressed in the direction of the floor, the electrodes of the second electrode pair become conductive through the second electric conductor.

To realize an antenna made thinner. A slot antenna includes: an antenna element having an aperture slit shaped slot; a reflector disposed by being opposed to the antenna element; a feeding device which is electrically and physically connected to the antenna element and the reflector; a short-circuiting device which electrically short-circuits the antenna element and the reflector; and a frequency switching device, which is provided on the slot, for switching resonance frequencies of the slot. The impedance generated by the approach between the antenna element and the reflector can be improved to prevent mismatching and the distance therebetween can be reduced to make an antenna thinner.

The present invention relates to a method for fabricating blackened conductive patterns, which includes (i) forming a resist layer on a non-conductive substrate; (ii) forming fine pattern grooves in the resist layer using a laser beam; (iii) forming a mixture layer containing a conductive material and a blackening material in the fine pattern grooves; and (iv) removing the resist layer remained on the non-conductive substrate.

The invention provides a thermoelectric conversion element having a lot of pn junction pairs per unit area and having a thermoelectric material chip which is hardly broken, and a producing method thereof. In the thermoelectric conversion element of the invention, plural substrates in each of which a film-shaped thermoelectric material is formed in a surface thereof are disposed. As a result, because the number of pn junction pairs per unit area is increased, a high output can be obtained. Because the thermoelectric material is formed into the film shape, reliability degradation caused by a breakage of the thermoelectric material can be prevented, even in the thermoelectric material having many pn junction pairs per unit area, namely, a sectional area is small.
