IPC: E01H12/00
Filed: 1989-01-10
Abstract: PURPOSE:To reduce the time for correction at the time of generation of deformation or damage in the blade or pin caused by overload by making a second pin among mounting pins of the blade shier pin. CONSTITUTION:Rake blades 150 are mounted at a bracket 143, and a large diameter first pin 151 is fixedly inserted into a hole formed at the position abutting against the inner face of a keep plate 144 in each side part 143b of the bracket. Second pins 152 made of synthetic resin and formed longer than the width of each groove 143c are, respectively, inserted into second mounting holes 150b of the rake blade 150. Then the rake blade 150 is mounted at the bracket 143 in a limited range around the second pin 152. It is thus possible to prevent the blade from being broken because only the second pin 152 is broken when overload is executed.

Title: Distance measuring device
Inventor: KAJIWARA YASUNARI
IPC: G01C3/00
Filed: 1982-01-13
Abstract: PURPOSE:To measure distance with high precision by adjusting the quantity of light incident to each image sensor through a liquid-crystal cell which varies in transmittivity with the intensity of the incident light, and controlling the charge storage time of the image sensor when the control by the liquid-crystal cell reaches its limit. CONSTITUTION:Light from a target 5 enters left and right lenses 1 and 2  through liquid-crystal plate cells 9 and 10 respectively. Through the lenses 1 and 2, images are formed on image sensors 6 and 7. The mean brightness of the incident light including external light corresponds to the mean value of output signals from the image sensors 6 and 7, but the output signals are generated for a short time as shown in a figure, so averaging over the overall time axis means little. For this purpose, the mean value of only the output signal (b) of every scanning pulse (a) is found and held in a memory until the mean value of a next scan is obtained, and it is used as a mean value.

Title: Image noise analysis method
Inventor: FURUKAWA ITARU
IPC: G06T5/00
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To provide the image noise analysis method by which noise information including noise amount and noise intensity as to a density is detected. SOLUTION: A filtering image 'U' from which noise is eliminated and an original image 'S' are selected alternately in response to a density block (blocks divided by threshold values T1 , T2 ) to which each pixel of the filtering image 'U' belongs, to obtain a discrimination image. The noise information as to each threshold level is detected by subtracting a density histogram HU of the filtering image 'U' from a density histogram HB for the discrimination image. The noise information is detected because the noise of the original image 'S' for the discrimination image in excess of the threshold level and the noise of the filtering image 'U' for the discrimination image that may exceed the threshold level without the smoothing processing are extracted by the subtraction processing.
