IPC: H01S5/12
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a distributed feedback semiconductor laser with excellent laser characteristics and reflection return light resistance, by composing an active layer of a well layer and a barrier layer to provide the active layer with quantum well structure and composing the well layer of a tensile strain quantum well layer. SOLUTION: A three-layered tensile strain multiple quantum well active layer 4 comprising a well layer and a barrier layer is formed on a diffraction grating 2. The well layer constituting this quantum well structure is preferably a tensile strain quantum well layer, for example, whose line width increase coefficient at gain peak wavelength is not more than 3. Since the tensile strain quantum well small in line width increase coefficient is used for the active layer 4 of the distributed feedback semiconductor laser thus constituted fluctuation in optical output caused by reflection return light is suppressed. That is, the resistance to reflection return light is enhanced. Also, fluctuation in oscillation wavelength caused by direct modulation is suppressed and a distributed feedback semiconductor laser with low chirping is obtained.

Title: Fuel pump
Inventor: ITO MOTOYA
IPC: F04C2/10
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To decrease costs by making a plurality of pump portions with fewer parts. SOLUTION: An inner gear 27, a circular intermediate gear 28, and a circular outer gear 29 are arranged together eccentrically forming two pump portions 12, 13. When a motor portion simultaneously rotates the three gears 27 through 29, the engagement amount of the trochoid teeth of each of the gears 27 through 29 continuously increases and decreases such that the capacity of each pump chamber 31, 32 formed between each of the gears 27 through 29 repeatedly increases and decreases with one rotation being a cycle. As a result, in the pump chambers 31, 32 in which the capacity is increasing, fuel is transferred while being sucked in from each intake port. The transferred fuel is then discharged from each discharge port in the pump chambers 31, 32 in which the capacity is decreasing.  With a pump portion 12 (pump chamber 31) on the inner peripheral side, fuel in the first fuel storage area is transferred to the second fuel storage area. With the pump portion 13 (pump chamber 32) on the outer peripheral-side, fuel in the second fuel storage area is fed to the fuel injection valve side.

CONSTITUTION:In a self priming pump provided with an impeller 4 rotated by a motor 1, plural reinforcement ribs 27 are formed to be extended radially in a back wall, setting an outer circumferential part 11 of a cylindrical shaft bearing part 10 as an inner side end 27a, for increasing strength of a pump casing 2. In this case, the inner side wall 27a of each reinforcement rib 27 is jointed with a base part 12 of the cylindrical shaft bearing part 10, and height of a joint part is set to be as small as possible. In generating the pump casing 2 by injection moulding, thermal interferrence of the reinforcement rib 27 with the cylindrical shaft bearing part 10 is eliminated in a cooling process, thereby bad effects on roundness, flatness, etc., of an inner surface of the cylindrical shaft bearing part 10 by thermal distortion in cooling can be eliminated.
