Title: Detecting method of original edge coordinate
Inventor: KISHI KOUJI
IPC: G06T1/00
Filed: 1984-03-17
Abstract: PURPOSE:To detect the size, position and tilt of an original without any error by counting a pulse in synchronizing with the main scanning and the sub-scanning and giving each count value corresponding to the start and last of the original as a profile data of the original. CONSTITUTION:A clock generator 5 generates a main clock having a repetitive frequency equal to the picture element number of a picture and gives it to a counter 7 and also to a sub-clock generator 6. The sub-clock from the main clock generator 5 and the sub-clock generator 6 is counted respectively by the counters 7, 8 and the count value is stored in registers 11-14. Registers 12, 14 act like giving the count value at that point of time to registers 12', 14' of the next stage by giving a discriminated output of a peak discrimination circuit 9 as a read pulse. Then a prescribed arithmetic processing is conducted at a CPU15 based on a data in a RAM16 storing coordinate data of all the scanning areas and the profile of the placed original is detected as the coordinate of the edge.

Filed: 1979-04-27
Abstract: PURPOSE:To facilitate the easy formation of the multi-beam type formation beam antenna by securing the square shape for the opening of the electromagnetic horn along with cutting the corner parts into the equal square form and then combining these squares. CONSTITUTION:For the opening of the electromagnetic horn, the square including a side (b) is cut off by the four corners of the square including a side (a+2b). The wavelength of the basic wave in the TE mode caused at the opening in that moment is nearly identical to the circular opening having the diameter equivalent to the length which is shortened properly in accordance with length (b). Accordingly, for the propagation mode of the electromagnetic wave, the equal circular opening equivalent to the averaged fringe form is obtained. As for the radiation pattern, nearly the identical pattern is secured between E and H faces if a:b=2:1 is satisfied. The horns of such shapes of openings can be combined easily through the approximate distribution. As a result, the formation is secured for the multi-beam type formation beam antenna which has the distribution of the optional and desired shape and can be mounted on the satellite.

Title: Measuring system
Inventor: KAWACHI MITSUYUKI
IPC: G06F11/34
Filed: 1986-03-12
Abstract: PURPOSE:To form a measuring instrument which is compact and high in the reliability of a measuring value by writing the same measuring data into the position where plural areas of a rewritable memory device are mutually corresponded to. CONSTITUTION:Into areas H1-H13, the same working times are respectively written and into areas N1-N3, the number of times of the turning-on of the same electric power source is respectively written. In short, when a writing primary factor occurs, the same time data are written into the same position of the areas H1-H3, and into the same position of the areas N1-N3, the data of the same number of the times are successively written. Thus, even when the electric power source is interrupted in a writing cycle (about 10ms) to either of areas and the data are destructed, the correct measuring value can be recovered by using other data. Namely, when the electric power source is turned on, three pieces of data in respective areas are compared, and when one value out of them is different, then, it may be rewritten by matching it to other two pieces of the same data.

Title: Wood pavement
Inventor: WATANABE TADAYASU
IPC: E01C13/06
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To improve economical efficiency and durability, and to simplify execution work by specifying a thickness of wood pavement, and including a single liquid moisture-curing urethane resin for causing urethane reaction and urea reaction in a binder as a main component. SOLUTION: An asphalt concrete layer 2 or a concrete layer is formed on a smoothed crushed stone layer 3 as an execution work base, and a wood layer 1 having a thickness of 20 to 40 mm is formed on it. The wood layer 1 is composed of a wood pavement material including a large number of wood chips having a small dimension, a binder and water, and includes a single liquid moisture-curing urethane resin for causing urethane reaction and urea reaction in the binder as a main component. The single liquid moisture-curing urethane resin forms an insoluble film on a surface by causing the urea reaction, so that surface strength increase, and since carbon dioxide generated in the urethane reaction is quickly blown off outside by adding an additive and prevents the occurrence of blistering, execution work time can be shortened.  Since a using binder is large extension/contraction quantity and is strong in adhesion to a wooden chip, flexibility and durability are also improved.
