Abstract: PURPOSE:To simplify the determination of a line concentration rate and the change of a protocol in accordance with the change of a stored terminal by providing protocol control data, which discriminates the protocol attribute of a connecting circuit, in the device main body of a protocol conversion line concentrating device having the function of line concentration as line switching. CONSTITUTION:When a start request occurs in an input/output terminal T20, the use conditions of higher lines 40-4i in a line control part 8 are discriminated through a lower line 20 by a protocol controller 2. The change of the line concentration rate and the change of the protocol are discriminated in an operation management controller 9 by commands inputted from an operation control console 60, and the assignment of higher and lower lines in the line control part 8 is changed through a control line 16 in case of the change of the line concentration rate. In case of the change of the protocol, for example, the change from a protocol A to a protocol B, a pertinent line in protocol control data 5 is deleted through the protocol controller 2 by the line control part 8, and a pertinent line is registered by a protocol controller 3.

Abstract: PURPOSE:To obtain a single longitudinal-mode laser at a high yield by a method wherein an opening used to form an internal reflection face is formed by using a rectangular etching mask having a width of 20mum or less in a direction perpendicular to an active layer from the upper part of the internal reflection face of an IRI laser so that a yield of a subsequent operation to fill the opening and a growth operation can be improved. CONSTITUTION:A stripe-shaped active layer 7 in a <011> orientation is formed; after that, an etching mask 14 with a rectangular window having one pair of opposite sides with a width of 20mum or less in a direction perpendicular to a stripe direction of the active layer is formed in a position where an internal reflection face 18 is to be formed; a second clad layer 9 and the active layer 7 are etched by using said etching mask; a groove is formed. By this setup, a chemical etching operation can be executed easily; on the other hand, a 211 plane does not appear in the groove; a layer whose quality is identical to the second clad layer 9 can again fill the groove and can be grown with good reproducibility. In addition, because the active layer is not curved at the internal reflection face, a single longitudinal-mode laser having a low threshold electric current nearly equal to that of an ordinary semiconductor laser can be given easily.
