Providing a packaging machine and a packaging method both of which are capable of packaging with an imperforate bag provided with no small apertures or no aerating part, can prevent contamination of foreign substances such as insects and can further prevent the packaging bags from being damaged or collapsed during storage in a piled state or transportation by execution of reliable deaeration. The packaging machine and a packaging method have a closing unit 4 which holds a vicinity of mouth a of a packaging bag A inserted with a deaeration nozzle held from opposed sides of the bag A, an airway securing unit, a shaping press unit and a temporary sealing unit.

A multi-directional input apparatus includes an operating member including a shaft portion which extends to the outside, a housing having an opening through which the shaft portion extends and configured to support the operating member in a tiltable manner, interlocking members moved by the operating member when the shaft portion is tilted, and detectors which detect changes in the positions of the interlocking members. A sliding member is externally fitted to the shaft portion such that the sliding member is movable in an axial direction, and a coil spring is disposed between a flange provided on the shaft portion and the sliding member. A rubbing surface of the sliding member is in elastic contact with a receiving surface on an inner wall of an annular edge portion surrounding the opening. The rubbing surface and the receiving surface are spherical surfaces centered on a tilting center of the shaft portion.

A force-feedback multidirectional input device includes a slider slidably supported by a support base and an operation knob joined to the slider. In a sliding operation, the slider operates in conjunction with actuating members included in a force-feedback unit. Therefore, a sense of force based on the sliding is fed back to the operation knob. Furthermore, the slider is elastically urged by coil springs toward an inner bottom surface of a housing space defined in the support base. In a depressing operation, the operation knob presses the support base downward against the urging force of coil springs. Therefore, a vertically movable member joined to the support base is moved downward along guide portions (convex rails and concave grooves). Thus, a push switch provided on a pedestal (circuit board) is pressed and activated by the vertically movable member.

The periphery of a mask (3) is formed higher than a region where a ball holding hole (3a) is formed, a work (1) is arranged at a lower section of the ball holding hole (3a) of the mask (3), and the ball holding hole (3a) and an electrode of the work (1) are aligned with each other. A ball (B) is applied on the mask (3), and in such state, vibration is applied to the mask (3) to move the solder ball (B) on the surface of the mask (3) and drop the solder ball (B) into the ball holding hole (3a). The periphery of the mask (3) is permitted to be lower than the ball holding hole (3a), and an excessive portion of the solder ball (B) is recovered from over the mask (3).

A haptic feedback input device includes a pair of driving levers journaled at a frame such that rotary shafts thereof are perpendicular to each other, an operating lever coupled to an intersection of the two driving levers such that it can rock, and a pair of rotary motors that apply feedback force to the operating lever via the two driving levers. In the haptic feedback input device, a pair of rotary encoders detect the relative dislocation amount of the operating level, and an absolute position detecting unit is composed of swing arms fixed to the two driving levers and photo interrupters that detect the existence of blocking portions formed at the swing arms and that output ON/OFF signals. A control unit calculates a reference position of the operating lever based on ON/OFF switching signals of the photo interrupters.

An optical fiber can efficiently excite metallic ions by a pump lightwave, and an optical fiber amplifier and an optical fiber laser light source both incorporate the optical fiber. The optical fiber comprises (a) a solid region that has a first region doped with metallic ions and a second region surrounding the first region and that allows a lightwave for exciting the metallic ions to travel in a multiple mode and (b) a third region surrounding the second region and having a plurality of holes stretching along the length of the optical fiber. The optical fiber has a structure in which the first region is supplied with the power of a lightwave that is included in the pump lightwave and that is in a mode having no intensity peak at the center axis of the solid region.
