Abstract: PURPOSE:To improve the performance of paste filling work by burrying a plate grid into a muddy paste of a desired specific gravity, and dewatering the paste while maintaining the grid in the paste, thereby allowing the grid to retain the thus-dewatered paste thereon. CONSTITUTION:While muddy paste 1 of the specific gravity of 2-3.5 being stored in a vessel 2, a plate grid 3 is burried into the muddy paste 1 by its own weight and an application of mechanical vibrations. Next, a pair of dry cloths 5 are pressed continuously against both sides of the plate grid 3 in the directions of solid arrows by rollers 4 so that the plate grid 3 is moved in the direction of a broken arrow, removing water from the paste 1 of the plate grid 3. When dewatering, the dry cloths 5 sandwich the paste 1 of the plate grid 3 from the upper and lower sides at the places of the rollers 4 and absorb water from the paste 1. The dewatering process continues until the thickness of the plate grid 3 becomes equal to that of the paste 1.

IPC: G01S13/93
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To improve reliability in estimating a collision by surely correcting a shift of a peak frequency of reflecting waves and detecting a highly accurate relative speed. SOLUTION: FM modulation waves are transmitted to an automobile 1 as an obstacle via a transmitting antenna 2, a receiving antenna 3, a radar head 4, a low pass filter 5, an amplifier 6, an A/D converter 7 and a triangular wave signal generator 8. Reflecting waves are received and a frequency spectrum is extracted at a spectrum extraction part 9a of an MPU 9. A peak frequency is detected by a peak frequency detection part 9b. A distance to the automobile 1 and a relative speed are detected from the peak frequency by a distance.relative speed detection part 9c. A collision estimation part 9e estimates a collision based on the distance and relative speed.  At this time, stability for a fixed time of the distance to the automobile 1 and relative speed is judged based on the extracted frequency spectrum by a relative speed correction value detection part 9d, so that a correction value for the relative speed is detected. The relative speed is corrected by the detection part 9c on the basis of the correction value.

Abstract: PURPOSE: To improve the pressure fixing strength of the object to be fixed by providing a difference of about 0.5 to 12% to the surface speeds of the upper roll and lower roll which hold the object to be fixed therebetween.  
     CONSTITUTION: Pressure rolls 3, 4 are connected by means of gears 5, 6 of the same number of teeth and revolve at the equal number of revolutions but the outside diameters of the pressure rolls 3 and 4 are differed by about 5% and therefore the surface speeds of the rolls differ.

A spring 8 for applying the pressure in the normal direction of the pressure rolls at their contact faces is provided to the object to be fixed which passes between the pressure roll 3 and pressure roll 4. A slight difference in the surface speeds of the rolls enables the higher pressure fixing strength than that by conventional ones even under the same linear pressure to be obtained.
