IPC: G01S7/36
Filed: 1987-05-20
Abstract: PURPOSE:To obtain a high suppression effect by executing an arithmetic operation in a real time by an analog processing in accordance with a prescribed algorithm. CONSTITUTION:In a radar device which is constituted so as to eliminate an incident disturbing wave from a side lobe area of a main antenna 1 by providing an auxiliary antenna 2, an algorithm for calculating an optimum weight value corresponding to a signal input from both the antennas 1, 2 is executed by an analog signal processing, and also, calculated in a real time. The arithmetic operation is executed in accordance with a prescribed expression, and first of all, an output of the main antenna 1 and an output of the auxiliary antenna 2 are provided to a mutual correlation part 15 and the correlation is taken. Subsequently, from an output derived by providing the output of the auxiliary antenna 2 to a self-correlation part 14 and an output of the mutual correlation part 15, a weight value is calculated. Also, this weight value is multiplied by the output of the auxiliary antenna 2 in a weighting part 13, and thereafter, subtracted from the output of the main antenna 1. In such a way, an original convergent speed which the algorithm has can be obtained, and such a rounding error as a digital arithmetic circuit has is not generated in an arithmetic circuit, therefore, a high suppression effect is obtained.

Title: Overflow water sound insulation device
Inventor: TOMINAGA MASAYUKI
IPC: E02B7/20
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To reduce the noise due to falling water by stretching a flexible sheet on the upper edge of a gate and the subgrade of the outflow side in an overflow weir using a derricking gate. SOLUTION: One end of a duck inserted rubber sheet flexible sheet 2 as a sound insulation sheet is fixed by a fastener 3 on the upper edge of a derricking gate 1, and the other end is fixed by a fastener 3' on a subgrade or can be detached by a string and the fastener. The derricking gate body 1 is rotatably provided on the subgrade by a shaft 4, and derricked through a wire 5 by a winding device. Thereby since the flexible sheet 2 constitutes a mild inclination face in the state where the derricking gate body 1 is erected, overflow water flows on the inclination face. Thus, noise due to the overflow water by direct falling can be prevented. In addition, since the sound insulation sheet 2 has flexibility, the derricking gate body 1 does not get in the way even when it is push down.

Abstract: PURPOSE:To obtain a filter with broad band characteristic by providing a means to allow a PLL circuit to control a steep change in a control signal, and driving the PLL circuit with a reference signal having a frequency fref in a frequency band fw. CONSTITUTION:A phase comparator (PFC) 51 detects a difference of rise times of input signals 511, 531, and outputs a signal 513 (UP signal) having a pulse width corresponding to its time difference when the signal 511 rises early and outputs a signal 514 (DOWN signal) when the signal 531 rises early. Moreover, a loop filter (LPF) 52 consists of a current source (current: Ip) turned on/off by UP, DOWN signals and a capacitor (capacitance: C). The oscillating frequency fvco of a voltage controlled oscillator(VCO) is controlled by an LPF output voltage Vg and an output signal 541 of a control circuit 541. Thus, the filter for broad band or high frequency is easily realized.

Filed: 1979-09-27
Abstract: PURPOSE: To provide a lead alloy for lead accumulator grating that causes little cracks by a method wherein a lead wire into which sulfur, selenium, or tellurium is preliminarily embedded is added into a molten alloy lead for melting.  
     CONSTITUTION: Sulfur, selenium, or tellurium is extruded from a die at a temperature close to its melting point so that a lead wire containing it is produced. A low- antimony lead alloy containing about 2W3% of antinmony is charged in a closed type melting oven, is heated, and kept at a temperature a little higher than about 310°C. As an example, a lead wire embedded with sulfur of specified amount is added into the oven, the oven is closed, the pressure is raised to about 500 atmospheres to prevent sulfur from sublimation. Thereafter, the temperature is raised to finally reach about 420W450°C. The obtained lead alloy contains about 2W2.5 times of sulphur and develops a large effect in preventing so-called scorch.
