Title: Pulse generator
Inventor: NOJIMA KENICHI
IPC: H03K3/53
Filed: 1990-11-28
Abstract: PURPOSE:To generate the steep rise of a pulse and to reduce the fluctuation of the peak value of the pulse by using an insulation rod arranged between insulation supports fitted to both ends of a ground metal pipe to support a coaxial conductor and moving a ground electrode provided on the inside of the ground metallic pipe in the radial direction of a ground metallic path. CONSTITUTION:When a load 10 connected to a distributed constant line is fluctuated, a driving device 24 is used to move a ground electrode 23 in the radial direction of the distributed constant line, thereby changing the distance between the ground electrode 23 and an intermediate conductor 8. Thus, the static capacitance between the ground electrode 23 and the intermediate conductor 8 is easily changed to compensate a change in a pulse voltage due to load fluctuation. Moreover, the movement of the ground electrode 23 is implemented by the driving device 24 provided on the outside of the ground metallic pipe 20. Thus, the static capacitance among the conductors is changed to generate a steep rectangular wave pulse with a high voltage at all times and the pulse voltage is maintained constant.

Filed: 1993-12-21
Abstract: PURPOSE:To provide a semiconductor laser, which is formed by a wafer process without using a cleavage and is provided with a good resonator mirror. CONSTITUTION:A semiconductor laser is provided with a resonator mirror, which is constituted of a side surface 1a formed by etching and a flattened layer 4, which is grown on the side surface 1a and has a flat crystal face. The layer 4 has a crystal face having the same flatness and verticality as those of a cleavage surface utilizing a difference in growth rate due to a difference in the crystal orientation of a growth surface. As the side surface 1a formed by etching has a structure 13, a step, which is generated on the crystal face of the surface 4a of the layer 4, does not overlap with the light emitting position of a waveguide 3. Accordingly, the semiconductor laser can be formed using an etching and an integration and the improvement of a productivity using a through water process can be realized.

Title: Photodetector and manufacture thereof
Inventor: MORIKAWA TAKENORI
IPC: H01L31/0352
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To reduce steps due to formation of facets on an Si substrate and avoid breaking the anode electrode, the facets being formed by increasing the thickness of a photoabsorptive layer of a photodetector formed by the selective epitaxial growth. SOLUTION: A photodetector has photoabsorptive layers 5a, 6a, 7 with a contact layer 8 formed in a recess of a substrate by the selective epitaxial growth. The total thickness of all these layers is greater than the depth of the recess surrounded by a side wall oxide film, thereby reducing the steps due to forming of the facets at the inner corners of the recess. This prevents leads of an anode electrode electrically connected to the upper contact layer 8 from disconnection.
