Abstract: A plurality of strings are stretched over a frame, constituting an overall framework of a body of a piano, with their respective rear-end engaging rings engaged by corresponding pins provided on the frame. There is also provided a string-bounding preventing member that, in case any one of the strings snaps or breaks, prevents the broken string from disengaging from the corresponding pin to bound violently away from the pin. The string-bounding preventing member is, for example, a strap member that is passed through the respective engaging rings to thereby connect together the strings. The string-bounding preventing member allows the broken string to be left connected with the other strings and hence stay in place on the frame without bounding.
Abstract: An initial ball forming method for wire bonding wire and wire bonding apparatus that uses: a capillary through which a wire is passed; a torch electrode made of a low-melting-point material that contains, for instance, tin; and a direct-current high voltage power supply. When the direct-current high voltage power supply is turned ON, a space discharge occurs between the tip end of the wire and the torch electrode, resulting in that the wire tip end melts and is formed into a ball and that the tin of the torch electrode is also heated to a high temperature and diffused into space, so that ionized plus tin ions are attracted to the tip end of the melted wire, thus causing tin to adhere to the surface of the ball-shaped tip end of the wire, and forming an initial ball that has a low-melting-point coating material adhered to its surface.
Abstract: An upright keyboard musical instrument has an open/close board attached to the top position of a case, wherein the lower surface of the open/close board is subjected to mirror surface finishing and is supported by a lid prop, which is rotatably arranged in proximity to the top board to rotate about a support axis and is formed in an L-shape to have a plurality of support surfaces, realizing different angles for the open/close board being opened. The mirror surface of the open/close board projects images representing internal members of the case, such as an emblem and actions. By appropriately rotating the lid prop, it is possible to realize a desired angle for the open/close board, thus realizing tone volume control and visually entertaining effects in musical performance.

Abstract: A vehicular lamp 1 including a lamp unit 2, in which a light-emitting diode 2a is used as the light source, and a cover member 4, which is provided between the lamp unit 2 and an outer lens 3 of the lamp and located near the inside surface of the outer lens 3 so as to cover the lamp unit 2 except its light-emitting region. The cover member 4 is formed of a material that has good heat conductivity, and heat generated by the light-emitting diode 2a is transferred to the cover member 4 and to the outer lens 3, thus heating the outer lens.
Abstract: A tailpiece of, for instance, an electric guitar including a bridge main body attached to the guitar main body by two protruding stud screws so as to be moved and adjusted in the direction of the stretched strings. At both ends of the bridge main body, first and second string supports for supporting first and sixth strings are formed integrally to protrude inwardly. Between the first and second string supports, a first bridge saddle member for supporting the second and third strings, and a second bridge saddle member for supporting the fourth and fifth strings, are provided. These saddles are connected to the bridge main body by saddle adjustment screws so as to be moved and adjusted in the forward and backward direction. The first and second bridge saddle members are moved along the surfaces parallel to the direction of the stretched strings.
Abstract: It is to provide an imaging lens that maintains optical performance and achieves reduction in size and weight. The imaging lens comprises, in order from an object side towards an image surface side, a first lens which is a meniscus lens having a positive power whose convex surface faces the object side, a diaphragm, a second lens which is a meniscus lens having a positive power whose convex surface faces the image surface side, and a third lens which is a biconcave lens having a negative power, wherein the following conditions are to be satisfied; 1.3?L/fl?1, 0.8?f1/fl?0.6, 0.12?f1/f2>0, ?0.1?f1/f3??0.25 (where, L: entire length of the lens system [distance from the surface of the object side of the first lens to the image taking surface [air reduced length]], fl: focal distance of the entire lens system, f1: focal distance of the first lens, f2: focal distance of the second lens, and f3: focal distance of the third lens).
Abstract: A wire bonder including two link driving mechanisms and a head supporting stage provided with a bonding head via fluid pressure so that the bonding head is movable in the horizontal plane. Each link driving mechanism is formed by a motor, a driving arm, and a movable arm. The movable arm that extends from the driving arm of the first link driving mechanism is fastened to the bonding head, and the movable arm that extends from the driving arm of the second link driving mechanism is rotatably connected at its one end to the bonding head. A thrust aiming at the center of gravity of the bonding head is applied to the bonding head by the movable arms, thus moving the bonding head around.
Abstract: A steel material that has on its surface a non-hexavalent-chromium type corrosion-resistant coating film formed by a composite of a metal layer and a resin layer. The steel material having or not having a copper layer is formed with 1) a Zn and/or Zn-based alloy layer, 2) a Zn/Ni alloy layer which is on this Zn and/or Zn-based alloy layer, 3) a de-Zn layer which is on the Zn/Ni alloy layer and is obtained by chemically treating the surface of the Zn/Ni alloy layer, and 4) at least one resin covering layer which is on this de-Zn layer, which are successively formed to make a corrosion-resistant coating film, the corrosion-resistant coating film, which is superior in adhesion between the metal layer and resin layer, being obtained by way of taking into account the use of a trivalent chromium type chromate layer instead of a hexavalent chromium type chromate layer (which is a substance that places a burden on the environment).

Abstract: A vehicular lamp including a light-emitting element 10 that emits light at a greater diffusion angle in the lateral direction than in the vertical direction, thus enabling the light to be incident on the rear face 34a of a horizontally elongated inner lens 34 with high efficiency. The rear face 34a has a cylindrical surface that extends in the lateral direction, and the curvature of a convex curve, which forms the cross-sectional shape of the cylindrical surface taken along the vertical plane parallel to the optical axis Ax, gradually reduces according to the increase in the distance from the optical axis Ax in the lateral direction, thus allowing the curvature of the convex curve to be maintained at a substantially constant value in the lateral direction and further preventing the diffusion angle of the light into the lens in the vertical direction from increasing in the lateral direction.
