Title: Safety traveling device for vehicle
Inventor: KAMIMURA HIROKI
IPC: G01S13/93
Filed: 1992-12-21
Abstract: PURPOSE:To prevent a warning due to unnecessary estimation and erroneous operation such as automatic braking by properly estimating the distance with an obstacle and securing the safety. CONSTITUTION:When information on the obstacle is not outputted from a radar 3, an estimation means 22 estimates at least the present value of distance between the self vehicle and the obstacle based on the information stored in a storage section 21. A contact possibility judgement means 12 judges the possibility of the contact between the self vehicle and the obstacle based on the information from the estimation means 22. On the other hand, if no information on the obstacle is outputted from the radar 3 when the self vehicle is operated, a regulation means 23 regulates the estimation by the estimation means 22.

Title: Method for suppressing fading of green color of plant
Inventor: AKASAKA AKINOBU
IPC: A01N63/02
Filed: 1991-11-28
Abstract: PURPOSE:To safely and effectively suppress the degeneration of green color of a plant suggesting the aging of the plant by extracting a photosynthetic procaryotic microorganism obtained from a natural source and applying a small amount of the extract to a green plant at the optimum stage. CONSTITUTION:A photosynthetic procaryotic microorganism such as cyanobacteria and photosynthetic bacteria is extracted and the extract is applied to a green plant at a stage most suitable for suppressing the degeneration of the green color of the plant (the optimum stage differs by the kinds of plant). The degeneration of color can sufficiently be suppressed at an extremely low concentration of the extract. The process has excellent safety because the raw material is originated from natural sources.

IPC: H01M4/66
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To use a very thin steel plate to enhance battery performance by forming an Ni or Ni-alloy hard layer on the thin steel plate, and subjecting the steel plate with the hard layer formed thereon to plastic deformation at a predetermined rate to produce cracks in the hard layer. SOLUTION: A thin steel plate is plated with a hard metal and then subjected to cold rolling process at a predetermined draft to produce a number of cracks only in a hard layer part such as a plating layer, the percentage of the crack area being within a fixed range of 5 to 60%. In this case, a part of an active material layer infiltrates cracking parts present on the surfaces of the hard layers of the cracks to prevent dropping of the active material as a whole. The steel plate to be formed into a core has the cracks formed in its hard layer and when necessary a rustproof surface treatment layer is formed thereon. The hard plating is Ni-P plating, Ni-Sn alloy plating, or the like. Therefore, the use of the very thin steel plate is made possible to allow an increase in number of turns in a battery.

Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To enable the first-out of a transfer material, prior to the feeding of an original, without increasing the scale and cost of a device by discriminating whether the original is the final one or not, based on the result of the detection of a detecting means and controlling the fact that the first-out of the transfer material is executed or not, based on the result of the discrimination. SOLUTION: In an original setting tray, original size sensors 51-56 for detecting the size of the original are arranged in the vicinity of the rear end corner of the original. The CPU 70 of a copying machine main body checks the outputs of the original size sensors 51-56 after a specified time lapses from the feeding of the original, to further recognize that the next original exists or not, so that it is judged that the first-out of a paper sheet can be attained or not. When the outputs after the specified time lapses are in ON states, that the original still exists is judged by the original size sensors 51-56, to continue a copying operation. When the outputs after the specified time lapses are in OFF states, the feeding of a copying paper is stopped to execute the copying operation for the final page.
