Title: Receiver
Inventor: SATO KAZUMI
IPC: H04J11/00
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a receiver that effectively compensates distortion of a transmission line in a direction of frequency base caused by multi-path. SOLUTION: In an OFDM receiver that demodulates a digital data series through synchronization detection, a reception section 2 obtains a frequency characteristic of a response of a transmission line by using a frequency spectrum of a reception signal and a frequency spectrum of a reference signal and filters the frequency characteristic of the response of the transmission line in a direction of the frequency base. A delay time of a received delay wave is measured and the band width of a filter 8 is set based on the measurement result. Distortion of a waveform of the reception signal is compensated depending on the frequency characteristic of the response of the transmission line and the digital data series is demodulated by using the reception waveform after distortion compensation.

Title: Overflow type multi-stage gate
Inventor: SUZUKI MAKOTO
IPC: E02B7/26
Filed: 1983-04-08
Abstract: PURPOSE:To increase the water depth permitting overflow over the wider range by reducing minimum height of a gate by providing a falling gate in a tilting manner on the upper part of the uppermost stage water gate of a multi-stage type gate consisting of two or more stage water gates. CONSTITUTION:A lower stage gate 1 and an upper stage gate 2 having a height H2 is provided to a support structure having a maximum gate height H1 in a vertically movable manner. A falling gate 3 of the same width as the upper stage gate 2 is provided in a tilting manner to the upper part of the upper stage gate 2. If h/h + H2 = K(where h is the adjustable allowance of the falling gate 3), H2/H1 =1- K/2 - K is obtained, and therefore, when the value of (h) is increased to increase the value of K, the H2/H1 ratio can be made smaller than that in the conventional type. In case where water depth is 2H2 or more and the amount of overflow is small, the falling gate 3 is tilted and the height (h) is adjusted to regulate the amount of overflow. In case where the amount of overflow is much or water depth is 2H2 or less, also, the upper stage gate 2 is lowered and the amount of overflow is finely adjusted by tilting the falling gate 3.
