Title: Optical isolator
Inventor: KIYONO MINORU
IPC: G02B27/28
Filed: 1988-02-18
Abstract: PURPOSE:To easily miniaturize an optical isolator and simplify positioning by providing an external supporting body where a through hole to which an optical fiber can be inserted without a gap and a groove traversing this through hole are formed. CONSTITUTION:The optical isolator consists of three elements (an external supporting body 11, a Farady rotator 12, and optical fibers 13 and 14). With respect to the external supporting body 11, a groove 11b having a certain width is formed across an optical fiber guide through hole 11a, which is extended in the axial direction of a cylindrical ferrule used as a connector between optical fibers, at right angles. When the Farady rotator 12 and optical fibers 13 and 14 are merely inserted to the groove 11b and the through hole 11a of the external supporting body 11, mutual positional relations are surely fixed. Consequently, precise working is unnecessary to simplify positioning, and the inexpensive and small-sized optical isolator is realized.

Title: Data transfer system
Inventor: KIMURA YOSHIHIRO
IPC: G06F13/38
Filed: 1988-02-17
Abstract: PURPOSE:To transfer data at a high speed by turning on an interruption flag corresponding to the position of a byte following the transferred one and turning off the preceding flag every time data is transferred to a data buffer from a 2nd interface. CONSTITUTION:When the data of a specific quantity is inputted to a data buffer 1 with the data transferred from a 2nd interface 4, an interruption flag (wait bit) 1 corresponding to the next byte is turned on. Then the bit 1 is changed when the data of a specific quantity is inputted to the buffer 1 with the next data transferred from the interface 4. Therefore, the transfer of data is carried out again via a 2nd interface 2 even though this transfer of data is interrupted by the flag 1 owing to a fact that the flag 1 is changed by the transfer of data via the interface 4. Meanwhile no interruption is applied to firmware. Thus the data transfer speed is increased with omission of intervention of the firmware.

Title: Semiconductor laser
Inventor: UEHARA KUNIO
IPC: H01S5/00
Filed: 1986-02-18
Abstract: PURPOSE:To reduce an irregularity in incident light intensity to a photodetector disposed at the rear of a light emitting element according to the position of the photodetector by disposing the distance of a light emitting position at the end of a semiconductor laser and the outermost layer surface of the electrode nearest to the emitting position to 10mum or shorter. CONSTITUTION:A distance from an active layer 10 to a boundary 13 between crystal electrodes is increased at an electrode outermost layer 11 of the side fusion-bonded to the same heat sink 2, and a distance from a light emitting unit position 101 to the surface 21 of the heat sink 1 is 10mum or longer. The formation of a thick electrode layer by a normal depositing method is not so practical, and a thick gold layer of 3mum or larger is adapted by the plating. In case of h=10mum, the width of the irregularity in the incident light quantity to the photodetector having 200mum of photodetecting diameter is approx. 1.3:1 in calculation, and in case of h=15mum, it becomes approx. 1.1:1 in calculation. Even if the increase in the irregularity due o the displacement from the approximate value occurring in the actual case is considered, the irregularity in the incident light quantity is largely improved as compared with the case of h 5mum.
