Abstract: PURPOSE:To sufficiently reduce the threshold current, by coupling a semiconductor laser and a diffraction grating with an optical waveguide, forming a first, a second and a third electrode on the semiconductor laser, the optical waveguide, and the diffraction grating, respectively, and forming a common or independent electrode corresponding with the above electrodes. CONSTITUTION:On a substrate 21, an optical waveguide 23 is coupled with a BH laser 22, and formed so as to connect it to a diffraction grating 24. In the case where the laser 22 is made of, e.g., InGaAsP/InP system material, InGaAsP whose band gap is larger than the active layer 221 of the laser 22 is used for the optical waveguide 23. On the BH laser 22 part, a first electrode 25 for controlling is formed, and on the corresponding part with the optical waveguide 23 and the diffraction grating, a second and a third electrodes 26, 27 to control the refractive index are formed, respectively. A common electrode 28 for each of them is formed. By applying a forward or backward voltage between an electrode of the diffraction grating part and an electrode corresponding with it, the refractive index of the optical waveguide of the diffraction part is controlled, so that the oscillation wavelength can be made to coincide with the wavelength at which a gain curve becomes maximum.

Title: Semiconductor device
Inventor: SHIMADA TOSHIYASU
IPC: H05K1/18
Filed: 1992-08-19
Abstract: PURPOSE:To prevent a deformation of an outer lead in a resin-sealed type semiconductor device for surface-mounting. CONSTITUTION:An upper-sided resin 3 is located on the opposite side to the bending-directional side of a bent outer lead 1. The upper-sided resin 3 is so formed that its end is located between the projected positions of the two parts of the outer lead 1. One of the two parts is the terminating end of the outside buckling of a first bent part 1a which is located in close proximity to the upper- sided resin 3. The other part is the end of the outer lead 1. Thereby, external forces are prevented from being applied to the outer lead 1 directly. Also, since the region of the outer lead 1, wherein it is apt to be deformed substantially, is made short and in its turn the strength of the outer lead 1 is improved, the deformation of the outer lead 1 is prevented.

Title: Output circuit of high frequency power amplifier
Inventor: SUGAI YOSHIKAZU
IPC: H03F3/189
Filed: 1983-11-22
Abstract: PURPOSE:To attain the high frequency power amplification with high stability and high efficiency by connecting the 1st filter which transmits the signal component and the input of the 2nd filter which transmits the higher harmonic wave component in parallel to the output of an amplifier, connecting a higher harmonic wave absorbing resistance to the output of the 2nd filter to absorb the higher harmonic wave component and therefore preventing the reflection of the higher harmonic component due to the amplifier. CONSTITUTION:The using carrier frequency component of the signal amplified by an amplifying element 1 is transmitted through the 1st filter 4 and delivered from an output terminal 6. The higher harmonic wave component is prevented by the filter 4 and not delivered to the terminal 6. Thus the higher harmonic wave component is transmitted through the 2nd filter 5 and absorbed by a higher harmonic wave absorbing resistance 7. Therefore the amplification of the higher harmonic wave component is avoided to attain the highly stable amplification of signals.

Filed: 1988-09-05
Abstract: PURPOSE:To enable a pulverized coal to burn from a low load to a high load by changing a ratio of a pulverized coal flow by means of opening and closing the intervals of louvers by a movable cylinder. CONSTITUTION:In the case where the load of a pulverized coal burner 10 is low, since the concentration of the pulverized coal is lowered, it is in a condition to draw out down to the position at which a movable cylinder 25 is shown by a broken line in the righthand figure. Thereby, because the intervals between louvers 20 are opened and a low concentration side flow of part of primary air in a mixed flow 19 is separated, a high concentration side flow 23 causes a weight ratio of the pulverized coal and the air to be rich. On the other hand, in the case where the load of the pulverized coal burner 10 is high, the movable cylinder 25 is inserted up to the position which is shown by a full line in the righthand figure and the whole primary air and pulverized coal is flowed as a high concentration side flow 23.

Abstract: PURPOSE:To automatically clean the water algae in a precipitation basin while preventing the collision of a moving body and an obstacle such as the end part of a flooding weir, by controlling the rising and falling of a rotary brush corresponding to the running of the moving body running along the longitudinal direction of the flooding weir. CONSTITUTION:A rotary brush 25 is preset to a depth to be cleaned so as to counterbalance the upper and lower position of said brush and, after a stand 13 is run along rails 8, 9 and fixed in a non-runnable state by clamping a lock bolt, the rotary brush 25 is rotated to remove the water algae at the appropriate place of a precipitation basin 1. When the rotary brush 25 reaches a place slightly before an obstacle such as the extended end 3a of a trough 3 with the forward movement of a sludge collecting machine 6, the rotation of the rotary brush 25 is stopped while the brush 25 is raised to be forwardly moved without hindrance. In addition, the brush 25 is fallen and rotated by the return movement of the sludge collecting machine 6 to remove the water algae by the brush 25. As a result, the water algae in the precipitation basin 1 can be automatically cleaned while preventing the collision of the sludge collecting machine 6 with the obstacle.

Abstract: PURPOSE:To improve the efficiency of access and the security of data control by adding identification (ID) information for identifying each data string to the data string, recognizing the ID information and selecting and reading out only the specified data string. CONSTITUTION:An IC card registers the ID information for identifying a data string in its internal RAM, and in case of writing an inputted data string, the ID information in the RAM converted by using a numerical formula and the converted ID information is added and written to the inputted data string. In case of reading out the written data string, the ID information registered in the RAM is similarly converted by using the numerical formula and a data string to which the ID information coincident with the converted ID information is added is read out. In case of reading out an objection data string, only the data string having the coincident ID information can be read out. Consequently, the efficiency of access and the security of data control can be improved.
