摘要： On a substrate of n-type GaAs are sequentially formed an n-type cladding layer (AlGaAs, Al content x=0.07, thickness t=2.86 &mgr;m), an n-type optical waveguide layer (GaAs, t=0.49 &mgr;m), an n-type carrier blocking layer (AlGaAs, x=0.40, t=0.03 &mgr;m), an active layer (composed of an In0.18Ga0.82As quantum well layer and a GaAs barrier layer), a p-type carrier blocking layer (AlGaAs, x=0.40, t=0.03 &mgr;m), a p-type optical waveguide layer (GaAs, t=0.49 &mgr;m), a p-type cladding layer (AlGaAs, x=0.20, t=1.08 &mgr;m), and a p-type cap layer (GaAs) in which a pair of n-type current blocking layers (GaAs) are buried. With this construction, the occurrence of a wavelength spit due to a higher-order mode can be inhibited thereby stabilizing a higher power operation.

This creates a refractive index difference between the active region 34 and buried regions 33 in which each of the current blocking layers 24 exists, thereby forming a refractive index guide structure. Thus, it is possible to obtain a high-output semiconductor laser device of the refractive index guided type which is easy to manufacture.

摘要： Sentences corresponding to internal statuses of a robot device or the like are created and uttered, thereby expressing the internal statuses. The robot device or the like comprise means for recognizing an external status, and means for generating an emotion based on the internals status, whereby a change in the emotion is reflected upon a dialogue. The internal status is not associated with a sentence, but it exists independently of the system and is always varied depending on various external inputs and internal changes of the system. Accordingly, even when the same question is made on the robot device or the like, the contents of a reply are changed depending on the internal status at that time, and a manner of providing a reply also differs depending on the internal status.

摘要： A robot system includes a speech recognition unit for converting speech information into text information, and a database retrieval unit for extracting a keyword included in the text information from a database. By designating a plurality of basic actions on a speech basis, and storing an action record, a combined action formed by combining the plurality of basic actions in time-series order can be named as a new action only in voice-based interaction. A user can designate complicated continuous actions by using only one word, and can easily have a conversation with the robot.
