A multistage transmission includes a swing claw member having a pin-receiving portion adapted to receive a pin member and an engaging claw portion on respective sides opposite to each other with respect to swing center, and swung by the advancement and retraction of the pin member to allow the engaging claw portion to establish engagement and release the engagement; and biasing means for biasing the swing claw member in a swing direction of bringing the engaging claw portion into engagement. The biasing means is a compression spring interposed between the inner surface of the engaging claw portion of the swing claw member and the opposing surface of the gear shaft. The multistage transmission uses multiple swing claw members of the same kind, instead of swing claw members of different kinds.

A multistage transmission is provided that smoothly operates with a small force without the necessity of a shift clutch, that does not cause a loss of switching time during shifting, and that does not cause escape of a driving force as well as provides a small shift shock. When shift drive means executes upshift to a one-step-upper speed-change stage reduced in reduction ratio by one stage, normal rotation odd-numbered stage cam rods Cao and normal rotation even-numbered stage cam rods Cae alternately operate normal rotation odd-numbered stage engaging members Rao and the normal rotation odd-numbered stage engaging members Rae for shifting.

A computer system comprising storage devices having different characteristics, a client computer, and a file access controller managing the storage devices with the HSM is disclosed. The file access controller provides a normal directory tree and a virtual directory tree, according to the configuration, and provides a first file stored in a first storage device through the normal directory tree and the virtual directory tree. And, the file access controller switches providing of a second file stored in a second storage device, depending on a used directory tree, which is used by the at least one client computer, and which is the normal directory tree or the virtual directory tree. Examples of the switch are about accessibility of the second file and recall processing of the second file.

A projection display apparatus is placed on an installation surface forming a horizontal plane and projects an image onto a projection plane provided on a horizontal plane. The projection display apparatus includes: an imager that modulates the light emitted from a light source; an projection unit that projects the light emitted from the imager onto the projection plane; and an acoustic device that outputs a sound in the vertical direction.

A transmission casing for a bicycle has sufficient strength and rigidity and has a simple structure while being capable of hermetically sealing a transmission body of the bicycle. In a transmission casing for a bicycle is covered with a casing and a plurality of transmission shafts supported by the casing. The transmission casing includes a light-metal-made reinforcing member made of aluminum, a light alloy or the like which supports shaft portions of the plurality of transmission shafts, and a fiber-reinforced-plastic-made cover member which is integrally laminated to an inner surface of the light-metal-made reinforcing member so as to hermetically seal the transmission body. The light-metal-made reinforcing member has a strength necessary for supporting the plurality of transmission shafts, and the fiber-reinforced-plastic-made cover member has a residual rigidity by subtracting rigidity obtained by the metal-made-reinforcing member from the rigidity necessary for preventing the deformation of the whole casing.

A first light source arrangement pattern is defined by: defining segments opposing to each other and arranged at end positions out of three segments in a first unit and three segments in a second unit, as light source arrangement positions; and defining one of three segments in a third unit, at the same position as the segment defined as the light source arrangement position in the first unit, as a light source arrangement position. A second light source pattern is defined by defining segments out of the segments in the first unit, the second unit, and the third unit, at end positions opposite to the segments defined as the light source arrangement positions in the first light source arrangement pattern, as light source arrangement positions. The first light source arrangement pattern and the second light source arrangement pattern are alternately arranged in the vertical direction.

To accurately obtain fluorescence intensity in a variable passband. Provided is a fluorescence observation apparatus including an excitation light source that emits excitation light; a Fabry-Perot resonator including a variable passband in which the wavelength of light that passes therethrough changes with changes in distance between the surfaces of optical members opposing each other with a distance therebetween, a fixed passband in which the wavelength of light that passes therethrough does not change irrespective of changes in the distance between the surfaces, and a transition band therebetween; an excitation-light cut filter that blocks passage of the excitation light; a band cut filter having a cut-off band including the transition band and not including the wavelength of the excitation light; and a photodetector that detects fluorescence that has passed through the Fabry-Perot resonator, the excitation-light cut filter, and the band cut filter.

Disclosed is a constantly-meshing-type multi-stage transmission which can be operated with small forces, does not need a clutch for gear shift, has no loss of changeover time at the time of gear shift, and in which a loss of the driving force is prevented. Driven gears n1, n2, . . . n5 are supported on a hollow driven gear shaft 12 in a manner engageable with and disengageable from a hollow driven gear shaft 12 via swing pawl members 24, 25. The transmission has first engaging means 25 for engaging the gear shaft 12 with a first driven gear n1, so as to effect synchronous rotation thereof; and second engaging means 25 for engaging the gear shaft 12 with a second gear n2, one step lower in reduction gear ratio than the first gear n1, so as to effect synchronous rotation thereof. When making an upshift by changing over the engaging means 25 from the engagement with the first gear n1 to the engagement with the second gear n2, the gear shift is made by engaging the second gear n2 with the gear shaft 12 through the second engaging means 25 while the first gear n1 is being in engagement with the gear shaft 12 through the first engaging means 25.
