Abstract: A blade assembly (16) for electric hair clippers includes a stationary blade (34) having a plurality of teeth (68) arranged in a row, and a reciprocating blade (36) having a plurality of teeth (82) which complement the stationary blade teeth. A cam eccentric (28) which is turned by a shaft (30) attached to a motor moves the reciprocating blade in a back-and-forth motion through a set operating stroke (A), determined by the lateral distance the cam moves during its rotation. A guide bar (96) maintains the reciprocating blade in a blade guide (48) parallel to the stationary blade throughout the operating stroke, but not through the maximum stroke (B) the blade can travel when the blade assembly is removed from a handle (12) for cleaning or other servicing. Anti-lock ribs (56) or an anti-lock bar (156) are provided on the blade guides to engage the guide bar throughout the maximum stroke distance, thereby maintaining the reciprocating blade parallel to the stationary blade throughout the maximum stroke distance. The blade assembly is removably secured to the handle of the clipper by snaps or the like without the use of screws.

Abstract: A novel optical subassembly arrangement is proposed. The subassembly comprises a silicon-based submount including a plurality of openings for placement of the various optical components utilized to form the optical subassembly. In particular, a silicon wafer is processed (e.g., etched) using conventional techniques to simultaneously form a large number of individual submounts, each submount processed to include a number of openings. The silicon processing may be sufficiently controlled such that active alignment of the components is minimized. An important feature of the design, when associated with an isolated embodiment, is that the silicon submount is formed to include openings for both the laser and isolator optics such that the openings are disposed along a thermal transport path through the silicon substrate from an attached thermoelectric cooler (TEC). Therefore, the laser and isolator optics are maintained at the same operating temperature. In one embodiment, the TEC may be attached to the underside of the substrate so as to form a cantilever arrangement with the substrate. In this embodiment, the isolator's magnet may be disposed to surround the substrate in a manner such that physical contact is avoided. The physical separation between the substrate and the magnet thus frees the TEC from having to unnecessarily cool the magnet.

The temperature characteristics of the logarithm-compressing section (58) are compensated in a temperature compensating section (59). The amount of the toner deposition is calculated in a toner depositing amount calculating section (43) based on a difference between the data during non-deposition of the toner and the data during deposition of the toner, the data being obtained from the logarithm-compressing section (58). Further, image forming conditions are changed in a control section (36) in accordance with an output signal denoting the calculated deposition amount of the toner so as to control the density of the image formed.

Abstract: An optical fiber clamp, having a plurality of V-shaped grooves (11), stores coated optical fibers (13) in the respective V-shaped grooves (11). The coated optical fibers (13) are held by a pressing force of the clamp. A cushion portion (24), having an abrasion-resistant smooth film layer (23), is provided on the side of an optical fiber pressing surface of the clamp. The cushion portion (24) applies a constant pressure to the optical fibers (13) through the abrasion-resistant smooth film layer (23) and absorbs any differences in the outer diameters and other dimensional peculiarities of the optical fibers (13). Thus, the optical fibers (13) in the V-shaped grooves (11) can be arranged and held uniformly, so that batch fusion and connection can be performed on a multicore fiber with a minimum loss of connection. The optical fiber clamp minimizes axial displacements of respective optical fibers.
