Patent JP-H01123503-A (JP)
Title: Horn antenna
Inventor: ABE AKIRA
IPC: H01Q13/02
Filed: 1987-11-09
Abstract: PURPOSE:To improve the axis symmetry of a radiation characteristic and a low side lobe characteristic by fitting plural resistance plates having a width dimension smaller than a horn aperture diameter vertically to the aperture surface to the horn inner wall near the aperture surface of a conical horn antenna. CONSTITUTION:Resistance plates 31-34 are fitted at a horn inner wall surface 12 of a part near a horn aperture surface so as to be vertical to a horn aperture surface 11 and the horn inner wall surface 12. A width W of a radius direction in the horn aperture surface of these resistance plates is sufficiently smaller than a radius (r) of the aperture surface and a thickness (t) of the resistance plates is sufficiently smaller than a wavelength at a use frequency. Namely, since resistance plates 31 and 32 are arranged on a (y) axis along the inner wall surface, the electric field component of the (y) axis direction near the inner wall surface is attenuated. Since resistance plates 33 and 34 are arranged on an (x) axis, the influence is small to the electric field component of the (y) axis direction and the (x) axis direction component, which is an intersection polarization component, is attenuated. Thus, the side lobe characteristic and axis symmetry of the radiation characteristic can be improved.

Title: Electrically erasable and writable programmable read only memory
Inventor: AKITA IKUKO
IPC: H01L29/792
Filed: 1989-10-27
Abstract: PURPOSE:To always preserve data in a normal EEPROM by detecting that a memory cell is destructed, modifying the address of the EEPROM according to a detected result and writing data to the normal memory cell of the EEPROM where the destruction does not occur. CONSTITUTION:When the selected memory cell is destroyed, '1' is raised in a bit which has the output of a syndrome generating circuit 11. Accordingly, the output of an OR circuit 12 is made '1' and it is detected that the memory cell is destroyed. At such a time, since an address decoder 2 decodes the output of the OR circuit 12 as a most significant bit A8 of the address, a memory band 2 is selected and the output of the address decoder 2 selects the prescribed EEPROM memory cell, which is determined by address information A0-A7 of the memory bank 2, and executes erasing and writing. Thus, the data can be always preserved in the normal EEPROM cell.

IPC: E04G9/05
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To prevent troubles such as corrosion and dew condensation from developing in an exterior finishing material by leading excess water not used for the curing of a concrete to the outside by a method wherein passages for discharging the excess water are formed on the inside surface on the concrete placement side of a form member made of foamed synthetic resin. SOLUTION: Excess water, which is not used for the curing of a concrete during the process, in which the placed concrete cures, leaks to the surface of the concrete. Since the excess water passes through a covering material, these excess waters are discharged in near vertical grooves 31 and flow down in the grooves 31 and finally discharged outside through the gap provided at the lower end surfaces of form members 12 or the like. Accordingly, even at the stage for completing a building by interposing an exterior finishing material, the corrosion of a foundation, of the exterior finishing material or the like and the dew condensation near the surface of the concrete or the like can be prevented from developing. Further, even after the elapse of long period of time, no excess water is left near the surface of the concrete.
