Title: Greening revetment material
Inventor: KOMABASHIRI HIROYUKI
IPC: E02D17/20
Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To create inhabiting environments of aquatic animals and plants and to purify water by forming a material by a vegetation base body greening and protecting a bulkhead and a water holding sheet making a high polymer water absorbing body arranged on the lower surface as a part or all the of the material. SOLUTION: On a slope 1, a water holding sheet 2 of a greening revetment material 7 is laid. On the upper surface, a vegetation base body 3 is laid so that a bag-shaped part 4b of a net body 4 may be along a contour line. Next, an anchor bolt 8 is driven and fixed at a prescribed portion of the revetment material 7. Because fiber-shaped high polymer water absorbing body in the water holding sheet 2 sucks water by its own water absorbing force when a prescribed period elapses, moisture is easily secured, plant seeds 6a, stem and leave parts and stubs which are filled into the bag-shaped part 4b are germinated/rooted and greening on the slope 1 is contrived. Further, washing digging/collapse of a surface due to rainwater and flowing water is prevented.  Further, because the bag-shaped part 4b is projected to an upper surface of a base material 4a the slope 1 is pressed by weight of stone to be an aggregate of a vegetation base material 6a. As a result, a large-scaled equipment is not required and cost can be reduced.

Abstract: PROBLEM TO BE SOLVED: To combine a DS and an ES into one by providing a limit switch by which a switch of a motor for sliding a movable conductor placed between fixed contacts for the DS and for the ES is turned off in its fully opened or closed positions. SOLUTION: When a motor 50 for a DS is rotated in the direction shown by the full-line arrow while a disconnecting switch 31 and a ground switch 32 are in their open positions, a hook 79 is engaged with a roller 52a, and a clutch 52 for the DS is engaged to rotate first and second screw shaft 41, 42 to move both first and second nuts 45, 62 left. Then a movable contact 40 connected to the nut 45 is inserted into a fixed contact 35 for the DS, so as to close the disconnecting switch 31. At the same time, a roller 66 enters a notch 72 and rotates a lever 70, the other end of which in turn operates a limit switch 75 to turn off the motor 50. When the nut 62 is further moved left because of inertia, the clutch 52 is disengaged via a pin 87, a rod 83, a turning member 81, and the hook 79 to stop the shafts 41, 42.

Title: Inside reforming-type fuel battery
Inventor: MATSUMURA MITSUIE
IPC: H01M8/02
Filed: 1990-09-04
Abstract: PURPOSE:To obtain stable activity of a reforming catalyst and battery properties by dividing a reforming-reaction region composed of a plurality of reforming- reaction parts into small reforming-nonreforming reaction parts and controlling the quantity of the reaction while controlling the flowing ratio of the fuel gas supplied to both. CONSTITUTION:A fuel gas is introduced into a fuel gas flowing route 4 and distributed and supplied to a reforming-reaction small part 12 and a non- reforming-reaction small part 13 at a constant ratio. Then, since the reforming- reaction small part 12 holds a reforming catalyst 9, reforming-reaction proceeds and on the other hand the reaction scarcely proceeds in the nonreforming- reaction small part 13. The quantity of the reforming-reaction is thus equal to that in the reforming-reaction small part 12 and consequently the quantity of the reforming in the reforming reaction parts 11a-11e becomes controllable by controlling distribution ratio of the fuel gas to the reforming-reaction small part 12 and the nonreforming-reaction small part 13. In this way, uniform temperature distribution is obtained stably for a long period and the stable activity of a reforming catalyst and stable battery properties are obtained.

Title: Image retrieving device
Inventor: OKOCHI SATOSHI
IPC: G06F17/30
Filed: 1994-09-29
Abstract: PURPOSE: To efficiently retrieve a desired image even if the time when the image was registered, is not exactly clear. CONSTITUTION: When a prescribed number (n) of retrieving images, designation point P as the time estimating the registration of the desired image and attribute information Z before and after the designation point are inputted from a keyboard (101), a CPU calculates the number of registered data within the range of retrieval in a normal mode (105) and when the number of data is less than the prescribed number (n), the retrieval range is extended (109). Then, a correlation curve is generated so that the degree of coincidence can be maximum at the designation point P (113) and the images are retrieved in order from the highest degree of coincidence (115 and 117). Thus, the retrieval can be performed even without exactly recognizing when the image was registered, and labor and time for inputting priority can be saved.  Besides, since the retrieval range is extended, the prescribed number (n) of images can be secured.
