Title: Semiconductor optical devices and methods for fabrication
Inventor: TAKIGUCHI TOHRU
IPC: H01S5/12
Filed: 1994-06-17
Abstract: A semiconductor optical device includes a first semiconductor layer 4a, and a diffraction grating 5. The diffraction grating comprises portions of a superlattice layer grown on the first semiconductor layer and comprising alternatingly arranged second semiconductor layers 5a comprising a semiconductor material in which mass transport hardly occurs and third semiconductor layers 5b comprising a semiconductor material different from the material of the second semiconductor layers. The device further includes a fourth semiconductor layer, 4b grown on the diffraction grating by vapor phase deposition. In this structure, since the second semiconductor layers in which mass transport hardly occurs are included in the diffraction grating, the shape of the diffraction grating is maintained during the vapor phase deposition of the fourth semiconductor layer. Therefore, the thickness, amplitude, and pitch of the diffraction grating that determine the optical coupling constant are controlled with high precision. A pair of masks defining a striped-shaped region of the wafer is used, the masks being of different widths, to form the groove in which the superlattice is grown. <IMAGE>

Title: Filtering device for a washing machine
Inventor: LEE AM KYU
IPC: D06F39/10
Filed: 1997-05-30
Abstract: A filtering device 30 for use in a washing machine comprises a filtering web 31 with ribs 33 disposed on its outer surface forming a lattice and a knob member 35. The ribs 33 are formed together with the filtering web 31. The knob 35 provides the knob part for installing the filtering device 30 into the washing machine. The filtering web 31 is installed at a bifurcating entrance of a circulating pipe leading from a drain pipe which also leads to a drain hose (13, 11, 12, filter 20, figure 1). During a washing operation dirt circulating in the washing water in the drain pipe is filtered by the filter 30 and is then taken by the circulating pipe to a washing tub. The ribs 33 are disposed so that longitudinal directions thereof have a predetermined angle against the flowing direction of the washing water in the drain pipe. When the washing water in the drain pipe is in contact with the ribs, it is guided towards the edge areas of the filtering web 31 by the ribs 33, thus the washing water is distributed to the entire area of the filtering web 31. During a drainage operation when the washing water in the drain pipe is discharged outside through the drain hose, the ribs 33 cause turbulence in the water causing dirt on the filter web 31 to be reduced.

Title: Fuel injector driver with premagnetisation phase
Inventor: FISCHER WERNER
IPC: H01F7/18
Filed: 1997-11-07
Abstract: The regulated current waveform (figure 2) applied to a fuel injector 100 solenoid comprises successively a premagnetisation phase, a high current valve movement phase, and a holding phase. The load current as sensed by resistor 120 is compared to the desired current waveform by amplifier 133 which controls field-effect transistor 110. To reduce the thermal burden on the regulating transistor 110, shunt transistor switches 140 and 145 are turned on respectively during the premagnetisation and hold phases so that most of the load current is diverted through resistors 150 or 155, thereby reducing dissipation in the transistor 110. The shunt switches may be activated also during the high current valve movement phase.
