Title: Crawler
Inventor: IMAI SEIICHI
IPC: B62D55/24
Filed: 1982-03-05
Abstract: PURPOSE:To prevent a crawler from being inclined to one side even when the left and right parts thereof are asymmetrical in shape, by approximately equalizing the projected plan areas of the left and right parts of the crawler with driving holes taken as a center. CONSTITUTION:When the crawler 2 is traveled on a place of weak ground, lugs 5 and the crawler 2 as a whole tend to sink because of the presence of notches 1, so that earth is effectively raked by the lugs 5 on the front and rear sides of each of the notches 1. Therefore, a driving or propelling force can be easily obtained, and slipping can be reduced. In addition, since the grounding areas, namely, the projected plan areas of the left side part (a) and the right side part (b) of the crawler 2 with respect to a center line (c) are approximately equal to each other, the crawler 2 can be prevented from being inclined to one side on the ground, even though the notches 1 are provided only in the left or the right part with the result of an asymmetrical crawler shape.

IPC: F23N1/00
Filed: 1983-03-08
Abstract: PURPOSE:To suppress abrupt change in feed fuel so as to make stable burning possible at all times even when interrupt processing is carried out by a microcomputer, by prolonging the time of one cycle of control of fuel supply when interrupt processing is carried out. CONSTITUTION:When a water content information intake request is given, then after a cycle time is reset, an arithmetic and control section 101 starts the water content value information intake processing. That is, when a judgment that there is the water content value intake request is made, and if the time of one cycle set in a step 20 has already passed for example 5sec, 10sec is set again by the fact that the judgment that there is the water content value intake request is made. As a result, when water content value intake processing is carried out, the time of one cycle of control of fuel is prolonged by 5sec to become 15sec. Thus, the amount of the supply of fuel per unit time given to the burner can be prevented from increasing, and stable burning can be provided at all times.

Abstract: PURPOSE: To reduce an acoustic noise with a simple and efficient method, by using a controllable, electrical digital waveform function generator and outputting a nearly ideal current waveform. CONSTITUTION: Power supply drivers 14, 16, and 18 exist for each of motor coil windings A-N, B-N, and C-N during the starting phase of a motor 11.
