Title: Nitride semiconductor element
Inventor: MARUI HIROMITSU
IPC: H01S5/343
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To improve output of a nitride semiconductor element, lower forward voltage and the threshold voltage and improve electrostatic breakdown strength characteristic by providing a superlattice layer wherein a plurality of layers including first and second nitride semiconductor layers of which one layer at least is doped with n-type impurities are laminated between a substrate and an active layer. SOLUTION: A nitride semiconductor light emitting element has a superlattice structure which is formed between an active layer 6 and a substrate 1 and wherein a first nitride semiconductor layer 4a and a second nitride semiconductor layer 4b are laminated alternately in an n-electrode formation layer 4 wherein an n-electrode is formed. Therefore, an n-electrode formation layer is made a layer of good crystallinity. Furthermore, its resistance can be made low and a forward voltage Vf of a light emitting element can be made low. In this case, crystallinity of the n-electrode formation layer 4 and the active layer 6 can be made good by forming an undoped nitride semiconductor layer 3 between the substrate 1 and the n-electrode formation layer 4 and forming the active layer 6 on an undoped semiconductor layer 5 which is formed on the n-electrode formation layer 4.

Title: Packing bag for cut flower
Inventor: YAMAGISHI SATOMI
IPC: B65D85/00
Filed: 1991-07-16
Abstract: PURPOSE:To provide easy packing work to wrap cut flowers therein and capable of preventing water leakage therefrom. CONSTITUTION:Agar 5 or a water-impregnated high water-absorbing resin is filled in the bottom part 4 of a plastic film made bag 3 having an opening at the top. Cut flowers are inserted in the bag 3 from its top opening and bound up in a bundle by tying the upper part of the bottom part 4 with a string. In this way the cut flowers are supplied with water from the agar 5 or the water-impregnated high water-absorbing resin and there is no water leakage from a bunch of the cut flowers when it is turned upside down. As an alternative, a water-swelling material is attached to the inner surface of the bag near its bottom part and, after a liquid has been poured in the bag, the cut flowers are placed therein and the bag is then tied around the water-swelling material. In this way the water rises in the bag to swell the water-swelling material so as to prevent the water leakage.

Title: Map drawing system for navigation system
Inventor: HAKOZAKI KEIJI
IPC: G01S1/02
Filed: 1987-08-11
Abstract: PURPOSE:To draw the map of a current area automatically by demodulating information data sent on an FM broadcast and discriminating the area (current area) where a vehicle is positioned, and entering an FM broadcast reception state. CONSTITUTION:Map information is stored on a CR-ROM 11 corresponding to respective areas and the information sent on the FM broadcast is demodulated by an RDS signal demodulation part 23. A controller 24 discriminates the area where the vehicle is positioned currently from the information data, e.g. an area discrimination code and a broadcasting station name contained in an area discrimination code and a broadcasting program discrimination code, etc. and sends an index corresponding to the area to a CD-ROM control part 12. The control part 12 reads the map corresponding to the index out of the CD-ROM 11 and a navigation controller 14 performs specific display processing to draw the map on a CRT 15. Therefore, the FM broadcast reception state is only entered regardless of whether the vehicle is driven or not to draw the map corresponding to the current area automatically.

Title: Method for polishing surface of paper-making calender roll
Inventor: ITO JO
IPC: B24B5/37
Filed: 1994-08-25
Abstract: PURPOSE: To prevent a forged-steel calender roll from vibrating during rotation so that it can be surface polished while rotating stably by filling the forged-steel calendar roll with a liquid, and pressing a pressing roll against the side of the forged-steel calender roll opposite to the polishing side. CONSTITUTION: When a rotating grinding wheel 7 rotating in the same direction as a forged-steel calender roll 1 having a Shore D hardness of 90 or higher is brought into contact with the forged-steel calender roll 1 to polish the surface of the forged-steel calender roll 1, the forged-steel calender roll 1 is filled with such a liquid as water prior to polishing. Further, a pressing roll 4 is pressed against the side of the forged-steel calender roll 1 opposite to the polishing side. As a result the roll is kept from vibrating and held rotating stably. In addition, the liquid filling the roll 1 keeps the temperature of the roll 1 from rising with the heat of friction during polishing, so as to hold the surface temperature distribution of the roll 1 constant and thus keep the roundness of the roll from deviating.

Title: Underground consolidated body construction method
Inventor: OTA SOZO
IPC: E02D3/12
Filed: 1995-08-07
Abstract: PROBLEM TO BE SOLVED: To eliminate the waste of excess execution when an improved body is developed by varying jet energy in accordance with a long and short distance from the turning center of a monitor for jetting high pressure fluid jet to the profile of a consolidated body having a non-circular section to be constructed. SOLUTION: When a square consolidated body C1 is constructed four corners' positions x1-x4 and the middle points' positions y1-y4 are set, arrival distance L at where the high pressure fluid jet has to arrive is calculated from the formula: L=f(p, q and t), where: f: coefficient, P: pressure of high pressure fluid jet, q: discharge of high pressure fluid jet and t: jetting time. Then, when energy and positions x1-x4 and y1-y4 are respectively shown in the ordinate and abscissa, energy (p×q) is the maximum in the positions x1-x4, it is the minimum in the positions y1-y4, and when energy is subsequently varied among them, the square consolidated body C1 can be constructed. By the constitution, since the non-circular consolidated body can be easily constructed, the waste of excess execution can be reduced when an improved body is developed.

Title: Electrophotographic toner
Inventor: HARADA YOSHIAKI
IPC: G03G9/08
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To prevent filming of a toner to a carrier and to a photoreceptor surface and to obtain stable triboelectric characteristics and good image quality during copying many sheets by depositing a magnetic powder having a specified or higher FeO content and a specified average particle size on the surface of toner particles. SOLUTION: A magnetic powder having >=26 wt.% FeO content and 0.1 to 0.8 μm average particle size is deposited on the surface of toner particles. If a magnetic powder having <26 wt.% FeO content is used, triboelectric charges of the toner decrease during copying many sheets and splashing of the toner occurs. Moreover, the FeO content of the magnetic powder is preferably 26 to 32 wt.% to stabilize the triboelectric charges and image quality. Since a powder having >32 wt.% FeO content has high adhesion property to the photoreceptor surface, such problems may occur that the magnetic powder itself drops from the toner surface and deposits on the photoreceptor surface. The deposition amt. of the magnetic powder on the toner particles is preferably 0.3 to 3 wt.% to the sum amt. of the toner particles and the magnetic powder.
