Filed: 1986-12-09
Abstract: PURPOSE:To enable remaining detection output to be prohibitively controlled by judging that Doppler frequency is only that of 0Hz after CFAR (constant failure alarm rate) processing in the direction of a frequency axis. CONSTITUTION:A logical sum is taken from the output of a pulse Doppler filter 1 via a range direction CFAR circuit 2 and a frequency axis direction OR circuit 3 at every range bin in a frequency axis direction except a filter No.0 and outputted as a single range direction detection signal. On the other hand, the output of the filter 1 is inputted to a frequency direction CFAR circuit 4, detected with a target at every range bin, inputted to a zero Doppler detecting circuit 5 wherein the filter number from which the output is produced is checked. When the filter number is only 0 (zero), it is concluded that a Doppler spectrum is present in the neighborhood of 0Hz and deemed as a clutter to be removed. Further, the output of the filter 1 is compared (7) with the level reference value of a level reference value generating circuit 6 and resultant output is compared (9) with the detection reference number of a detection reference number generating circuit 8. The outputs of the circuits 3, 5 and 9 are judged (10) and the target is detected.

Abstract: PURPOSE: To easily confirm an aiming surface and to rapidly, accurately and safely conduct aiming by forming the one side of a body as the aiming surface and forming the other in a structure in which the light from the upper part of a front sight is guided to the aiming surface so that the aiming surface shines brightly. CONSTITUTION: The upper part of a transparent resin is formed in a crest shape so that the one surface of the body 1 having a lens effect is formed as an aiming surface 3. The other is formed from the end of the upper part to the lower part of the direction of the surface 3 of the body so that the angle of the end of the upper part is acute and the angle of the lower part is obtuse in an obliquely cut section 2. The obliquely inner surface is formed as a mirror with a prism, and the surface of the aiming surface 3 of the body is molded in a small rhomboid shape. Thus, the light from the interior is diffused, and the outer light is reflected. Accordingly, the surface 3 can be easily confirmed, and rapidly, accurately and safely aimed.  Since natural light is used, the illuminance of the surface 3 is observed in proportion to the brightness of the periphery, and hence the surface 3 is not excessively dark or not excessively bright.

Title: Lead-acid battery
Inventor: MACHIDA KAZUYUKI
IPC: H01M10/06
Filed: 1985-12-27
Abstract: PURPOSE:To increase charge recovery performance of an overdischarged battery by specifying a ratio of the amount of sulfuric acid and that of cathode active material. CONSTITUTION:If the amount (weight) of sulfuric acid and the amount (weight) of cathode active material are specified in a ratio of 0.6-0.8, charge current of the upper limit of power source capacity is immediately supplied when a completely discharged battery is charged by a constant voltage charge process. If the ratio is less than 0.6, the rising time of charge current is lengthened. Even if the ratio exceeds 0.8, the rising time of charge current is not shortened any more. Since increase in the amount of sulfuric acid decreases volume efficiency and weight efficiency, the upper limit of the ratio is limited to 0.8.
