Title: Semiconductor light emitting device
Inventor: KAMITE KIYOTSUGU
IPC: H01S3/06
Filed: 1988-06-20
Abstract: PURPOSE:To obtain light pulses characterized by no chirping and with an excellent extinction ratio by injecting second laser light into a first single-mode laser, absorbing the gain of the first laser which is deviated to the side of a short wavelength, separating the first laser light, and obtaining the signal light. CONSTITUTION:In the distribution of the gain of a distributed feedback DFB laser 12, the gain is increased more at the rise-up time than at the balanced time, and the peak of the gain is deviated to the side of a short wavelength. At this time, the light output of a DFB laser 10 is injected into the active layer of the laser 12. The light of the laser 10 is amplified at intense, intermediate and low degrees in response to the wavelengths based on the gains of the laser 12. Therefore, the excessive gain of the laser 12 whose wavelengths are shifted toward the short wavelength side is absorbed with the laser 10. Thus, oscillation in the light output of the laser 12 is adequately suppressed at the rise-up part, and the light pulse without chirping is obtained. There is no relaxation oscillation in intensity. In this way, the light pulse characterized by no chirping and an excellent extinction ratio is obtained, and the transmission characteristics can be improved.

Title: Bow rudder
Inventor: NOMA SHIGERU
IPC: B63H25/38
Filed: 1984-07-24
Abstract: PURPOSE:To decrease instability on steering while reduce the radius of curve when a boat takes a curve by providing a rudder made of a water switching board which has a fulcrum vertically in the draft on a bow and which can be turned to right and left with respect to the axis of said boat. CONSTITUTION:A rudder 2 is provided in the draft on a bow and is turned to the desired proceeding direction side from the axis of a hull as shown in the figure A when a boat is proceeding, to vary the direction of the axis of the hull by means of side pressure caused by a water flow and change in the introduction of water flow to the hull. When the boat is backing, the operation of the rudder is reversed marking it operate as in the case of the conventional rudder. The figure B shows that the boat is brought alongside the pier on the left side without varying its direction of axis as much as possible, as in the case of coming alongside the pier, etc. The operation of the rudder is reversed when the boat is parting from the pier. Thus, by operating the rudder on the bow in combination with the conventional rudder in the stern as appropriate, a direction varying point on the axis of hull can be brought closer to the center of the hull, rapidly increasing the side pressure for varying the direction of hull. Thereby, the radius of rotation of the hull can be reduced to facilitate the control of the boat when brought alongside or parting from the pier by means of the operation of the rudder.

Filed: 1989-06-16
Abstract: PURPOSE:To speed up the operating speed of a semiconductor device by a method wherein the outer peripheral surfaces of an intrinsic base region are encircled with an external base region, which has an impurity concentration higher than that of the intrinsic base region and is not bonded to collector and emitter regions. CONSTITUTION:In a single crystal silicon film 4, a P-type intrinsic base region 5 is formed on an oxide film 3 and N and N<+> collector regions 6a and 6b and an intrinsic emitter region 7 are formed on both sides of the region 5. A P<+> polycrystalline silicon film 8 which is used as an external base region is formed in the upper and lower directions of the region 5 and all the outer peripheral surfaces of the region 5 are encircled by the film 8 excluding the junction surfaces of the region 5 with the regions 6b and 7. Accordingly, a linking region results in not existing between the regions 5 and 8. Thereby, the base width of a transistor becomes the uniform region width of the intrinsic base region. Moreover, as the junction area of the region 5 with the region 8 is taken wide, a DC current-amplification factor at the time of a low-temperature operation can be remarkedly improved.

Abstract: PURPOSE:To form palladium silicide with good reproducibility, by forming a  palladium layer on the surface of an insulating film having an opening on a silicon  substrate, removing the palladium layer on said insulating film, and heat-treating  the palladium layer on the exposed surface of the substrate. CONSTITUTION:A silicon oxide film 22 at a part of which the opening is provided is deposited on the silicon substrate 21. The palladium layer 23 with the thickness of about 700Angstrom  is formed on the surface thereon by evaporation. Then the palladium layer 23 on the silicon oxide film 22 is removed. Thereafter the heat treatment is performed at 450 deg.C in an nitride atmosphere for about 10 min, and silicon 21 and  the palladium layer 23 are reacted. As a result palladium silicide 24 is formed to the thickness of about 1,400Angstrom . Then, aluminum metal layer 25 which is to become an electrode is formed by evaporation. Unnecessary parts are removed, and the intended semiconductor device is obtained. Since the palladium layer 23 has good adhesion with silicon 21 but poor adhesion with the silicon oxide film 22, palladium silicide never remains on the silicon oxide film 22.
