Abstract: PURPOSE:To improve the light coupling capacity between an optical fiber and an optical wave guide and to shorten the working time required for connection by sticking a plate-shaped material consisting of the same material as an optical waveguide substrate to the surface of this substrate and connecting a plate-shaped substrate for fiber guide consisting of the same material to said plate-shaped material on the same plane. CONSTITUTION:A plate-shaped material 3 consisting of the same material as an optical waveguide substrate 2 is stuck to the surface of the substrate 2 provided with an optical waveguide 5, and its vertical end part 8 is ground. Meanwhile, a plate-shaped substrate 4 for fiber guide consisting of the same material as the substrate 2 is generated and is provided with a groove 7 which guides an optical fiber 6. The ground end part 8 and the substrate 4 are connected on a substrate 1 consisting of the same material, namely, on the same plane so that the optical waveguide 5 coincides with the center of the groove 7 on the substrate 4, and the optical fiber 6 is inserted to the groove 7 and is adhered with an adhesive or the like, and the optical fiber 6 and the light guide 5 are connected. Thus, they are stably connected because the optical fiber 6 has the whole of the section brought into contact with the ground end part 8 on the side of the light guide substrate 2.

Title: Semiconductor laser pumped solid laser
Inventor: NAITO KENTA
IPC: H01S3/16
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To enhance the utilization efficiency of pumping energy for semiconductor laser pumped solid laser by an arrangement wherein a semiconductor laser pumps a solid laser with a wavelength making an optical transition from one specific level to another specific level of the solid laser. SOLUTION: At the time of laser transition from<4> F3/2 level (laser upper level) to<4> I11/2 level (laser lower lower level) of Nd<3+> , the oscillation wavelength of a semiconductor laser for pumping a solid laser corresponds optical transition from<4> I9/2 level (ground level) of Nd<3+> of the solid laser to the laser upper level. The Nd3+ is pumped from the ground level to the laser upper level with a light having such a wavelength and the Nd<3+> of laser upper level makes a transition to the laser lower level through laser transition without passing through a relax process of nonradiative transition. A laser light Y is obtained in that process and the laser lower level is relaxed to the ground level through nonradiative transition. The utilization efficiency of pumping energy on the order of 82-83% is attained and it is higher than ordinary utilization efficiency of 76%.

Title: Output buffer circuit
Inventor: SHIGIYOU TOMONAGA
IPC: H03K19/003
Filed: 1988-10-28
Abstract: PURPOSE:To suppress the production of malfunction by providing a power voltage control circuit limiting a power voltage applied to an output inverter circuit. CONSTITUTION:A gate voltage of an N-channel transistor(TR) 2 and a P-channel TR 3 is controlled by resistors 6-8 connected in series between a power supply and a ground and the TRs are component of a power voltage control circuit of an output inverter circuit. Since the output of TRs 4, 5 is not in full swing in a range of the power voltage, an output load capacitor 9 is not completely charged and discharged, a transient current is decreased, thereby decreasing the drive of an internal power supply due to a power impedance. Thus, an output buffer circuit hardly causing malfunction is obtained.

Title: Error correction system
Inventor: HATANAKA YUJI
IPC: G11B20/18
Filed: 1985-12-09
Abstract: PURPOSE:To suppress deterioration in inspection ability due to an increase in error rate by considering that all symbols can not be corrected when the number of flags added during the 1st decoding exceeds a specific number. CONSTITUTION:When an error is corrected, a received signal is inputted firstly and a syndrome generating circuit 1 generates a syndrome. In the 1st decoding, the error detection of a reed-solomon code and the error is detected. In the 2nd decoding, the number of flags added in the 1st decoding is counted by a counter 2, and the result is compared by a comparing circuit 5 with the specific number inputted from a P-ROM 11. When the number of flags is smaller than the specific number, decoding is performed by a program, the error position and error pattern are found, and wrong data is corrected. When the number of flags is larger, on the other hand, an incorrectable flag is outputted from a data input output terminal 20 for all symbols. Consequently, the detection ability when the error rate is low is improved.
