Title: Device for opening and closing lens barrier
Inventor: TAKEUCHI YOSHIHIRO
IPC: G03B11/04
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To open/close a lens barrier attached to a lens barrel without depening on the driving force of the lens barrel and to eliminate possibility that excessive operational force is exerted on the lens barrel at such a time by transmitting the driving force from an operation member to the lens barrier when the lens barrel is at least within a part of the moving range. SOLUTION: This device is equipped with the movable lens barriers 18 and 19, the operation member 13 provided apart from the lens barrel and operated at plural positions, and transmission mechanisms 16, 17 and 20 transmitting the driving force from the member 13 to the lens barriers 18 and 19 when the lens barrel is at least within a part of the moving range. Thus, the lens barriers 18 and 19 in the lens barrel are driven by the driving force from the member 13 provided apart from the lens barrel, so that the driving force of the lens barrel need not be distributed for the driving force of the lens barriers 18 and 19. Therefore, the driving mechanism of the lens barrel is constituted to be compact and the fluctuation of the driving resistance of the lens barrel is prevented, whereby the lens barrel can be smoothly actuated.

Title: Optical semiconductor device
Inventor: YAMAMOTO TAKAYUKI
IPC: H01S5/00
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To avoid the occurrence of crystal transposition even when the number of well layers is increased by added compression strain, by causing tensile strain at the end of the waveguide region in the optical guide layers that sandwich a quantum well structure layer. SOLUTION: An optical semiconductor device consists of a quantum well structure layer 34 that is flat in a gain region 30A and is thinner than the gain region 30A and tapered in a waveguide region 30B; clad layers 32, 36 formed above and below the quantum well structure layer 34; and optical guide layers 33, 35, formed between the clad layers 32, 36 and the quantum well structure layer 34, that are flat in the gain region 30A and tapered in the waveguide region 30B, and that produce tensile strain at the ends of tapers. This reduces the amount of compression strain of the optical guide layers 33, 35 in the gain region 30A. Since the total amount of compression strain in the gain region 30A is reduced, crystal transposition in the well layer 34w, where compression strain is exerted, is prevented.
