Title: Distribution feedback semiconductor laser
Inventor: KOBAYASHI KENICHI
IPC: H01S5/12
Filed: 1984-03-07
Abstract: PURPOSE:To realize a distribution feedback semiconductor laser characterized only in TE mode oscillation by a method wherein an optical waveguide constituted of a layer with its forbidden band width larger than that of an activation layer is coupled to a distribution feedback waveguide and its surface is coated with a metal layer with the intermediary of an insulating layer. CONSTITUTION:To an activation waveguide 10 including an activation layer having an uneven periodic structure 100, an optical waveguide 50 is coupled, with its forbidden band width larger than that of said activation layer. The waveguide 10 is provided with a clad layer 30 thereon. On the waveguide 50, through the intermediary of an insulating film 200, a metal layer 300 of Au or the like is provided. The end face of the activation region is so structured as to suppress the Fabry-Perot mode. Oscillation is generated by an oscillating frequency that is determined by the diffraction lattice organized by the periodic structure of the activation waveguide 10. Said light is coupled with the optical waveguide layer 50, to be reflected by its end face and return to the activation waveguide 10. Due to the metal layer 300, loss is greater in the TM mode than in the TE mode. Accordingly, a distribution feedback semiconductor laser oscillating only in the TE mode is obtained.

Title: Prefabricated scaffolding device
Inventor: TAKIZAWA MITSUHIRO
IPC: E04G1/36
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To simply prefabricate the scaffolding at a jobsite by making the prefabricated scaffolding device capable of coping with a transport device even when an interval between a obliquely moving transport device and another obliquely moving transport device disposed upward thereof is different at every jobsite. SOLUTION: A bracing member 3 is used for a horizontal assembling scaffolding device, and rotatably coupled at the middle point of a first beam body 43 the middle point of a second beam. When the bracing member 3 is used for an obliquely moving assembling scaffolding device, a parallelogram is formed when upper and lower locking means in one leg member 2 and upper and lower locking means in the other leg member are connected, since the erecting positions of one leg member 2 and the other leg member 2 disposed in opposition thereto are different. The first beam 43 and the second beam 2 are disposed on the diagonal of the parallelogram. Thus, a coupling position rotatably coupling both the beams is not the middle points of both the beams. In this case, the coupling position of both the beams can be easily determined.

Title: Antenna input circuit
Inventor: YAMAMOTO MASAKI
IPC: H04B1/18
Filed: 1991-03-08
Abstract: PURPOSE:To receive all channels of both VHF and UHF bands without deteriorating receiving performance. CONSTITUTION:In a VHF band reception mode, the switch diodes 5 and 25 becomes inconductive. Then a VHF band input circuit 2a acquired the band pass characteristic suitable to the VHF band reception after the cut-off frequency of an LPF is decided by the synthetic capacity of coils 21 and 22 and capacitors 24 and 27. In a UHF band reception mode, both diodes 5 and 25 conduct and the series resonance frequency is decided by the synthetic capacity of the capacitors 3 and 7 of a UHF band input circuit 30 and an inductor L1. With regard to the circuit 2a, the series resonance is secured by the coil 21 and the capacitor 24 and the cut-off frequency of the VHF band is reduced. Thus the signal of the VHF band is attenuated. Then the cur-off frequency is reduced to the VHF band signal in a UHF band reception mode only. Therefore the receiving performance can be improved for both VHF and UHF bands.

Title: Method for supplying high concentration slurry to boiler
Inventor: NAKAMURA YOUICHI
IPC: C10L1/32
Filed: 1983-03-18
Abstract: PURPOSE:To prevent increasing of investment for the installation of equipment, by a method wherein, after high concentration slurry is dried and crushed into pieces, it is fed to a pulverized coal firing boiler. CONSTITUTION:High concentration slurry 30, fed to a drier 20 through a pipe line, etc., is dried by the drier 20 so that the moisture content thereof is reduced to a moisture content included in pulverized coal. Pulverized coal lumps produced by the drier 20 are fed to a banker 10, and after it is pulverized coal by a pulverized 11, it is fed to a pulverized coal firing boiler 12 for combustion. This permits high concentration slurry to be burnt in the pulverized coal firing boiler, whereby this eliminates the need to build a high concentration slurry producing base and to change a combustion boiler into a boiler for firing both high concentration slurry and pulverized coal, resulting in the possibility to prevent increasing of investment for an installation.

Filed: 1990-02-23
Abstract: PURPOSE: To improve the vertical and horizontal resolution of a picture signal receiver by reproducing pictures having second visibility by accepting the difference signals of first signals indicating pictures having first visibility and the pictures having second visibility and adding the difference signals to each other. CONSTITUTION: A high-visibility camera 400 generates base-band signals having an effective frequency band width expanded to 8.4MHz and the signals are impressed upon a standard-visibility monitor 710 through a 4.2-MHz low-pass filter 1010. The band width-limited signals are also impressed upon a high- visibility monitor 1012. A subtracting circuit 1014 generates difference signals having a band width from 4.2MHz to 8.4MHz by subtracting the band width- limited signals outputted from the filter 1010 from the full-band width signals inputted to the filter 1010. The difference signals indicate the high-visibility part of the signals and the combination of the filter 1010 and circuit 1014 works as a high-pass filter. The difference signals are impressed upon the second input of the monitor 1012.  In the monitor 1012, an adding circuit 1018 receives the difference signals delta from the band width-limited signals, adds both difference signals to each other, reproduces high-visibility signals, and supplies the high-visibility signals to a monitor 714.
