Title: Method for manufacturing semiconductor ring laser
Inventor: NUMAI TAKAAKI
IPC: G01C19/66
Filed: 2001-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a gyroscope of ring laser type which is hardly affected by back-scattering and hardly causes lock-in phenomenon. SOLUTION: When sides of a light guide 1 are inclined with respect to the normal line of the growth face, the intensity of the back-scattering light is reduced and the lock-in phenomenon due to the nonlinear effect becomes hard to occur. For that purpose, the light guide 1 constituting a ring resonator is formed in the first place as shown in Fig. 1 (a) and then a corner mirror is formed as shown in the Fig. 1 (b). By forming a light guide 2 in a radial pattern by the first etching, there is no risk of oxidation of the surface on which the corner mirror is normally formed. In this way, unnecessary difference in level is not formed at the second etching, a sufficient vertical state can be obtained and the lasing threshold can be reduced. Also, the light guide 2 wider than the light guide 1 is formed in advance so that all the surfaces into which a laser beam enters become flat.

Title: Semiconductor ring laser gyro
Inventor: NUMAI TAKAAKI
IPC: G01C19/66
Filed: 2001-04-17
Abstract: PROBLEM TO BE SOLVED: To provide a ring laser gyro which is less liable to be affected by irregularities of side surfaces of light guides, and resulting in having little back scattering, and resisting the occurrence of lock-in phenomena. SOLUTION: In each of the light guides constituting a ring resonator, a high resistance layers 40 are formed on both sides of an active layer 24. Regions, having no light gain, are thereby formed on both sides of the active layer 24 having a light gain. The resistance layers 40 are in contact with air (refractive index of 1). The refractive index of a semiconductor is about 3.5, and the difference in refractive indices actualizes an index light guide structure. Further more, a gain light guide structure is formed in the index light guide structure. Since the resistance layers (semiconductor) 40 have no optical gain, light intensity is small at their interfaces. Even if the side surfaces of the light guides have irregularities, the light intensity of back scattering light is made small relative to laser light and the lock-in phenomenon, due to non-linearity effects being less liable to occur. The resistance layers 40 without optical gains can be actualized by proton injection or the like.

Abstract: PROBLEM TO BE SOLVED: To provide a revolving actuator, which can be used as a drive source for industrial machines, machines for public, and the like, to which an eccentric revolution motion is applied; and also copes with high-speed rotation. SOLUTION: The revolving actuator, has a plurality of stators 2, along the outer-peripheral rim on the revolving-orbit surface of a moving-element member 1; forms an electromagnet 4, which generates magnetic field in the revolving-axis direction, by winding a coil 3 on each stator; and has a eccentric shaft 5, which prevents rotation of the moving-element member 1 and makes it revolution motion with a certain radius. Further, since the moving-element member 1 comprises an electric conductor 6, and revolution motion is allowed by induced current flowing in the electric conductor 6 and electromagnetic force generated by the magnetic field in the revolving-axis direction, the revolving axis is parallel to the magnetic flux related to the generation of the magnetic flux and there is in principle no gap change between the moving element and the stator.  As the result, the actuator can be designed making the gap length sufficiently small, and copes with high-speed rotation.
