Abstract: PROBLEM TO BE SOLVED: To simplify execution of an earth retaining wall and improve working efficiency by continuously providing a plurality of rod-like bodies, forming a retaining wall body inclined frontward of the side of the lower end and mutually connecting the ends of the rod-like bodies by a concrete connection body. SOLUTION: After a plate-like ground sill 2 composed of concrete is laid on along a river bottom positioned frontward of a ground 1 composed of a slope, a plurality of rod-like bodies 3 composed of a concrete utility pole after removal are vertically arranged on the ground sill at a prescribed inclined angle, continuously provided so that the outer peripheral face abuts and a retaining wall body 4 inclined frontward of the side of the lower end is formed. Furthermore, the inside of a form 5 set on the ground sill 2 is filled with concrete, and after hardening, the form 5 is removed to form a lower connection body 6a so as to mutually connect the lower end of each rod-like body 3.  Since the form 5 used at the time of formation of the lower connection body 6a is compact, a series of handling is very simple, an amount of concrete filling is small, and a hardening time is shortened to remarkably improve a working environment.

Title: Manufacture of quantum box
Inventor: YOSHIKAWA TAKASHI
IPC: H01L29/06
Filed: 1991-11-28
Abstract: PURPOSE:To manufacture a quantum box having a shape-independing upon any plane orientation by a method wherein the droplet of In or Ga is formed, aluminum fluoride is formed, only a region covered with the droplet is etched selectively through dry etching, and a columnar or conical hole is formed. CONSTITUTION:An AlGaAs substrate 3 is irradiated with Ga molecular beams in a molecular-beam epitaxy device, thus shaping a Ga droplet 14. The AlGaAs substrate 3, on which a droplet adheres, is transferred to a reactive ion-beam etching (RIBE) device. When NF 3 plasma is generated and F atoms are made to reach the AlGaAs substrate 3 at that time, aluminum fluoride is formed on a surface section not covered with the Ga droplet 4. Consequently, RIBE by chlorine is conducted to the substrate 3 with the Ga droplet formed and aluminum fluoride forming layer 2, thus preparing a conical hole 1. Accordingly, a quantum box having a shape independing upon any plane orientation can be manufactured.

Title: Video signal processor
Inventor: STROLLE CHRISTOPHER HUGH
IPC: H04N5/44
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To reject interference of an identical channel by filtering an interference signal using an FIR filter in a carrier reproducing loop. SOLUTION: An output from an input processing circuit 12 is supplied to a rotator 16 through a feedforward equalizer 14. An identical channel notch filter 18 processes a base band outputted from the rotator 16 or a signal close to the base band. The filter 18 exhibits a zero through-put delay band pass response with attenuation notches for rejecting an NTSC-identical channel base band video carrier and chrominance subcarrier frequency. The filter 18 advantageously improves the performance of the equalizer 14 so that a proper coefficient control signal is applied from a multiplier 30 to the equalizer 14. Since the filter 18 is included in the carrier reproducing loop for reproducing the base band signal, the identical-channel-interference rejecting notch of the filter 18 accurately coincides with the frequency of the base band signal to be rejected.

Title: Circuit and method for reproducing carrier wave
Inventor: KOMATSU SUSUMU
IPC: H04L7/00
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To provide a carrier wave reproducing circuit with which a carrier wave can be satisfactorily reproduced even on the condition of the adverse reception state of a modulated wave and pull-in time can be shortened. SOLUTION: Concerning this reproducing circuit, a first complex multiplier 8 generates a first frequency converted signal by multiplying a first local oscillating signal into an input modulated wave and a second complex multiplier 11 generates a second frequency converted signal by multiplying a second local oscillating signal. In an automatic frequency control(AFC) loop, the frequency of the first local oscillating signal is controlled and in a phase locked loop(PLL), the phase of the second local oscillating signal is controlled so as to synchronize the phase with the modulated wave. In this case, after the AFC loop is operated by a loop control circuit 27, the PLL is operated and when phase synchronism is not established, the PLL is operated again after an offset adding circuit 19 is operated for applying offset to the first local oscillating signal.
