Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To provide an optical semiconductor device in which LD and PD optical semiconductor elements are mounted and connected to a substrate in longitudinal, lateral and height directions. SOLUTION: Solder 30 of the prescribed quantity is fed to the electrode pattern 13, which is formed on the surface of the recessed part 11 of an Si substrate 10, by vapor deposition, plating and printing, etc. An LD chip is picked up by an automatic mounting tool, and it is mounted in such a manner that the bump 22 of the LD chip 20 comes in recessed part 11. The solder 30 is fused by heating by a reflow device, etc. When the solder 30 is fused, the bump 22 is moved to the center part of the recessed part 11, and the LD chip 20 is closely fixed and connected to the prescribed position of the Si substrate 10. The recessed part 11 is formed on the correct position by etching and the bump is formed on the above-mentioned part by vapor deposition and the like.  As the quantity of the solder 30 is controlled in such a manner that it does not overflow from the recessed part 11, the LD chip can be precisely mounted on the substrate 10.

Title: Current control circuit for motor
Inventor: YAMAGUCHI ATSUO
IPC: H02P7/291
Filed: 1984-01-18
Abstract: PURPOSE:To detect a motor current even when a switching element is OFF by connecting a flywheel diode in parallel with a series circuit of a motor and a motor current detecting resistor. CONSTITUTION:A comparator 1 compares a motor current detected by a current detecting resistor 3 with a set value to control ON or OFF a transistor 9. When the transistor 9 is ON, a current supplied from a power source 5 to a motor 2 flows to a current detecting resistor 3. When the transistor 9 is OFF, the current flowed to the motor 2 flows through a current detecting resistor 3 and a flywheel diode 10. Thus, even when the switching element is OFF, the motor current can be detected to be sufficiently controlled.

Title: Detector of moving medium
Inventor: TAKAISHI KAZUAKI
IPC: B41J11/42
Filed: 1993-01-21
Abstract: PURPOSE:To promote the speediness and exactitude of detection by detecting the extent of output voltage in a photointerrupter with a hinge contacting with a moving medium, calculating the actual gradient of an output voltage curve, and comparing it with the setting gradient, then checking the detection operation. CONSTITUTION:When a contact piece is rotated as far as more than a certain angle with a hinge as the center by contact of a moving medium, an output voltage is generated out of a photointerrupter 10. This output voltage is converted into digital data by an analog-to-digital converter 15 at every setting time. In addition, two gradient calculating means 21 and 22 calculate the actual gradient of an output voltage curve with both the digital data at the last time and this time. Hereat these detection operation checking means 21 and 22 compare the calculated actual gradient with the preset setting gradient, and when the actual gradient has cane to more than the setting one, they confirm that the photointerrupter 10 has entered the detection operation. Subsequently, in the case where the actual gradient calculated by these gradient calculating means 21 and 22 has cane to zero, the detection definitive means 21 and 22 detect and confirm that the moving medium arrives at the specified position or runs past.
