    • A cylindrical shell main body constituting a muffler main body is formed of two layers of an inner shell and an outer shell and has a cylindrical shape with a cross section that is not a perfect circle but is defined by alternated small arc portions and large arc portions similarly to an oval, or the like. The outer shell of the shell main body has, in each of their small arc portions, four radially projecting beads continuously extending in a circumferential direction along the small arc portions and being a predetermined distance apart from one another in an axial direction, thereby allowing an upper and lower gaps between the inner shell and the outer shell in the respective large arc portions of the shell main body to communicate with each other through passages formed by the beads.

    • The present invention is an optical apparatus, e.g. an image display apparatus, which enables observation of a clear image at a wide field angle with substantially no reduction in the brightness of the observation image, and which is extremely small in size and light in weight and hence unlikely to cause the observer to be fatigued. The optical apparatus has an image display device (6), and an ocular optical system (7) for leading an image of the image display device (6) to an observer's eyeball (1). The ocular optical system (7) includes, in order from the image side, a third surface (5) which forms an entrance surface, a first surface (3) which forms both a reflecting surface and an exit surface, and a second surface (4) which forms a reflecting surface. The first to third surfaces (3 to 5) are integrally formed with a medium put therebetween which has a refractive index larger than 1. A bundle of light rays emitted from the image display device (6) enters the ocular optical system (7) while being refracted by the third surface (5) and is internally reflected by the first surface (3) and reflected by the second surface (4). Then, the ray bundle is incident on the first surface (3) again and refracted thereby so as to be projected into the observer's eyeball with the observer's iris position or eyeball rolling center as the exit pupil (1).

    • A photographic film cassette manufacturing apparatus, has a perforator for providing a long film with perforations and a cutter for cutting the long film into individual filmstrips to be contained in the film cassette driven synchronously with transport of the long film. A magnetic recording head for recording data on a magnetic recording layer of the long film is driven in synchronism with the perforator and the cutter. The long film is transported in a first direction before being cut into the individual filmstrips. In cooperation with the cutting, a trailing end of the individual filmstrip in the first direction is moved in a direction which is reverse to the first direction to secure the trailing end to the spool. A cassette shell consisting of a pair of shell halves is temporarily assembled by mating the shell halves together while containing a spool inside the shell halves, and thereafter opened to an extent that confining elements still confine the position of flanges of the spool. The trailing end of the filmstrip is inserted into the opened cassette shell and secured to the spool.

    • An image display apparatus which enables observation of a clear image at a wide field angle with substantially no reduction in the brightness of the observation image, and which is extremely small in size and light in weight. The image display apparatus has an image display device (7) and an ocular optical system (8) for projecting the image of the image display device (7) and leading the projected image to an observer's eyeball (1). The ocular optical system (8) has at least three optical surfaces, and a space formed by these surfaces is filled with a medium having a refractive index larger than 1. The three optical surfaces are defined as a first surface (3), a second surface (4), and a third surface (5), respectively, in the order in which light rays pass in backward ray tracing from the observer's eyeball (1) to the image display device (7). The optical surfaces are disposed such that light rays from the observer's eyeball (1) pass through the first surface (3) and are reflected by the second surface (4) and further reflected by the third surface (5), which is a reflecting surface having positive power, and the light rays reflected by the third surface (5) are reflected by the first surface (3) and pass through the second surface (4) to reach the image display device (7).
