Patent EP-0218344-A1 (EP)
Inventor: WESTBROOK LESLIE DAVID
IPC: H01S3/06
Filed: 1986-08-19
Abstract: The emission linewidth of a semiconductor laser can be reduced by operating it at a wavelength which is less than the wavelength of maximum gain at the threshold current, λ max. An assembly for carrying out such operation comprises a ridge waveguide laser provided with a distributed feedback (DFB) grating 9. The period of the grating 9 is selected to give a predetermined emission wavelength to the laser which is shorter than λ max. 
     The invention finds application in optical communications, particularly in coherent systems.

Abstract: The apparatus has a wiper assembly (10) disposed in such a manner that the wiper assembly (10) can be accommodated in an accommodating chamber (16) provided inside the body of the vehicle and in the vicinity of a window glass (12). The wiper assembly (10) is vertically moved between an accommodated position at which it is accommodated in the accommodating chamber (16) and a raised position at which the wiper assembly wipes the window glass (12). In addition, a wiper arm (56, 58) which supports a wiper blade (54) that wipes the window glass (12) is adapted to be capable of expansion and contraction. Accordingly, when the wiper is not used, the wiper apparatus (10) is accommodated in the accommodating chamber (16), so that it is possible to minimize the air resistance to the vehicle and reduce the size of the accommodating chamber (16).
