Title: Tire for atv
Inventor: KUWABARA TAKAO
IPC: B60C9/08
Filed: 1988-11-30
Abstract: PURPOSE:To improve wandering performance without impairing a riding quality by forming defined arc profiles between the equator point of a tread at the time of charging a regular inner pressure and a quarter point and between the quarter point and a maximum width point. CONSTITUTION:A reference profile L is formed with an arc 10 which passes a quarter point B at a length W1 of 1/4 the maximum width W from an equator point A at which an equator plane CO intersects the tread-portion surface of a tire in a charged condition with a regular inner pressure while having the center O1 thereof on the equator plane CO, and a second arc 11 which has the center O2 on a line X1 connecting the quarter point B to the center O1 and which is in contact with a perpendicular Y drawn to a tire maximum width point C. The zone R1 between the equator point A and the quarter point B is formed along the arc 10 while forming the zone R2 between the quarter point B and the maximum width point C inside the second arc 11. Thereby, the ratio of component of an impact force F is varied lowering the shear component F1 which incurs wandering to improve wandering performance, without incurring the lowering of a riding quality caused by the strengthened rigidity.

IPC: B65C9/26
Filed: 1992-10-15
Abstract: PURPOSE:To improve average throughput by forcing an attraction head to drop initially and having it freely fall from halfway of the dropping. CONSTITUTION:A label 43 issued by a label printer part 38 is attracted to an attraction head 12 by attractive force generated by an electric fan 10. When a product 44 is carried below the attraction head 12, a motor 26 normally rotates so that a roller 30 moves at a speed faster than naturally falling speed of the attraction head 12 along an arrow A, it comes into contact with a second protrusion 35 from upward to have it driven downward, and the attraction head 12 is lowered. While the roller 30 is dropping, a driving canceling means comprising a gradient running part of a chain cancels a driving state of the second protrusion 25, so that the attraction head 12 falls in a free falling state at a speed faster than the naturally falling speed to come into contact with the product 44. The attraction head 12 in contact with the product 44 stops with the label 43 attracted to a lower face, and immediately the motor 26 is reversely rotated to have the attraction head 12 raised.

Abstract: PURPOSE:To improve the operating rate of a device by providing a means which diagnoses whether or not plural pieces of hardware for measurement are in a state where there is no hindrance to the execution of a measurement program and a selecting means which selects stand-by hardware according to the diagnostic result. CONSTITUTION:A computer 1a edits the measurement execution program by using a tester language or translates it into object codes which can be executed by a sequence controller 2a. Then if a 3rd measurement voltage source 5 becomes faulty when a certain electronic circuit is measured, 1st-5th voltage sources 3-7 for measurement are named P1-P5 in order and a controller 2a diagnoses functions, so that it is judged that the voltage sources P1, P2, P4, and P5 are normal. On the other hand, when voltages sources that the computer 1a requires are denoted as Pa-Pc, object codes of the execution program are determined so that Pa=P1, Pb=P2, and Pc=P4 when the functions of those voltage sources are represented as P (same function). Therefore, the measurement execution program and hardware correspond to each other one to one and a measurement is taken.
