Title: Grain storage shed
Inventor: YAMAMOTO SOICHI
IPC: B65D23/00
Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To quickly recognize a quantity of grains received by a tray without returning the grains again to a storage tank for weighing. SOLUTION: A quantity to be weighed is limited since a weighing plate 144 is arranged in the opening part to a tray 140. A ruled line more that is printed as radial ruled lines 148 with a ruled line of 5 go (1 go is 0.18 liter) as the center. In the oblique ruled lines 148, a horizontal ruled line 148 coincident with the upper end of polished rice 104 is searched by inclining the tray 140. When this ruled line 148 and the upper end of the polished rice 104 coincide with each other, a figure corresponding to the ruled line 148 becomes a go figure. Thus, a weighing error can be eliminated since unmeasurable (incomprehensible whether or not the upper end of the polished rice 104 is horizontal) weighing when the tray 140 is in an ordinary state can be easily performed.

Title: Flame detector
Inventor: MASAI TADAHISA
IPC: F23N5/12
Filed: 1984-01-26
Abstract: PURPOSE:To make it possible to positively detect a flame by constituting a deformed part in a frame rod and detecting the existence of a flame by the change in the resistance value. CONSTITUTION:A first ring-shaped projection 13A is provided on the central part of a frame rod 13 and a second ring-shaped projection 13B on the tip end thereof. Sealing air exhausted from the tip end of a guide 5 flows along a base part of a rod metal fitting 10 and a base part of a frame rod 13 and comes into collision with the first ring-shaped projection 13A. Thereby, the sealing air flows toward the outer part being peeled off from the frame rod 13. Accordingly, the sealing air does not exist on the surfaces of the frame rods 13 downwardly of the frame rod 13A, and sufficient contact between the flame and the frame rod 13 is kept, and the flame is positively detected. Moreover, since the second ring- shaped projection 13B is formed at the tip end portion of the frame rod 13, a whirl 15 is generated at the rear stream part to include flame. Hence, the contact between the frame rod 13 and the flame is further strengthened.

Accordingly the carriage 6 follows the body 3 at the speed allowing the speed fluctuation of the conveyer 2. Besides the relative position deviation amount stemmed from the time necessary for calculating a speed command signal is corrected, thereby precisely following the tracking point.
