Title: Walking type working machine
Inventor: KUROMI AKISHI
IPC: B62D51/04
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To easily allow a walking type working machine to travel across a channel in a case where a running path such as a farm road is divided by an irrigation channel in such a way as crossing the traveling path and no footboard is built across there by constituting a front wheel and a rear wheel as drive wheels respectively. SOLUTION: A walking type mowing machine 1 is made to cross over an irrigation channel and the like which is formed across a farm road by dividing the traveling path. At first, a preceding one wheel out of a front wheel 9 and a rear wheel 10 is held up so that the machine travels only by the other wheel. As the preceding one wheel reaches the traveling path in the other side of the channel, the one wheel is made to ground and at the same time the other wheel is held up. The device is thus operated by traveling with only the preceding one wheel. The front wheel 9 and the rear wheel 10 are constituted as the drive wheels respectively so that the driving force for traveling the machine body can be sufficiently obtained from the drive force of only one wheel.

Title: Camera
Inventor: KOBAYASHI RYUICHI
IPC: G03B15/05
Filed: 1991-07-19
Abstract: PURPOSE:To prevent such a trouble that a failure photograph is taken because an irradiating angle is not suited by preventing photographing from being executed until detecting that the change of the irradiating angle of a stroboscope is finished when the focal distance of a lens is desired to be changed. CONSTITUTION:Since it is the telephotographing when zoom phase signals ZOOM1 and ZOOM2 are respectively 1 and 0, 3 is stored in a ZOOMR. Since it is the standard photographing when the signals are 0 and 0, 2 is stored. Since it is the wide-angle photographing when the signals are 0 and 1, 1 is stored. Besides, since the signals become 1 and 1 when they are positioned between phases, 0 is stored (127-133). The phase ZOOMR of the stroboscope and the focal distance conversion of the lens FZOOM are compared. Then, when they differ, a zoom driving sub-routine is called and the focal distance and the zoom phase are made to be suited (120). In such a case, since release interruption is inhibitted during the zoom driving of the stroboscope, light is prevented from being emitted while the irradiating angle of the stroboscope is not suited with the focal distance of the lens at a releasing time.

Thereafter, a plurality of points on an edge along, for example, the Y-axial direction are plotted in the vicinity of the coordinates A in the image V, and then, boundary coordinates a1, b1 are again obtained. Then a straight line segment D connecting between the coordinates a1, b1 is obtained. Further, a determining distance L between the line segment D and the coordinates A is calculated, and whether this distance D is large or small is checked so as to determine a degree of a missing. The result of the determination is feed-back to a control line, thereby it is possible to precisely know an inferiority occurring condition.
