Title: Load control mechanism for working vehicle
Inventor: KAMIYAMA HIDEKI
IPC: B60W10/10
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To uniformly hold the working load by constituting a load control mechanism in such a state as not controlling the output, when an engine rotation speed detecting means judges an engine rotation speed to be in a range with no possibility, of stall in judging 80 overload state. SOLUTION: When a movable swash plate of a hydraulic pump is moved to a set position by a lever operation of a continuously variable transmission 3 and a lever angle sensor S3 confirms the setting of the advancing area of the movable swash plate position, a controller C reads a detection load factor via a load factor monitor M1 and compares it with the set load factor set by a load factor setting device 23. When the former is larger than the latter, the set rotation speed is read by an axle sensor S4 and the detected engine rotation speed by an engine rotation speed monitor M2.  The controller C stores the set engine rotation speed reduction as a standard as the possibility of the stall, if the detection engine rotation speed is lower than the overload standard rotation speed, the movable swash plate is moved by a swash plate control motor 8 because of the possibility of the stall, and it is higher, there is no possibility of the stall so that it is left as it is.

Title: Echo eliminating device
Inventor: KANEMASA AKIRA
IPC: H04B3/23
Filed: 1985-04-02
Abstract: PURPOSE:To simplify control, to decrease the scale of hardware and to decrease a converging time by using a cascade connecting circuit comprising a subtractor and a sample-and-hold circuit in place of a random signal generator and providing additionally an interpolation filter, three polarity detectors, a correlation device, a multiplier and a switch. CONSTITUTION:In order that an adaptive digital filter 8 makes an adaptive operation, the condition is required that the probability that the polarity of a residual echo component in a difference signal (echo + reception signal - pseudo echo) being an output of a subtractor 10 is obtained accurately is not zero by a polarity detector 12. The sample-and-hold circuits SH1-SHR and a subtractor 16 are added to satisfy the condition. In this case, a switch 24 outputs an output of the subtractor 10 at the zero cross point of the reception signal and outputs an output of the subtractor 16 at other points. The correlation of outputs of the polarity detectors 23, 19 is calculated by the correlation device 20. The polarity of the difference signal and the pseudo echo appears at the output of both the detectors respectively and the correlation device 20 outputs a value corresponding to the quantity of the residual echo. Thus, the output is multiplied by 2a to form a step size and the polarity of the detector 12 is given thereto and the result is fed back to the filter 8 so as to reduce the converging time.

Abstract: PURPOSE:To make an engine startable with both automatic and manual ways, by installing each clutch between the starter pulley coupled with a crankshaft and reduction gears connected to a DC motor as well as between the reel connected to a starter rope and the starter pulley, respectively. CONSTITUTION:When a two-cycle engine is automatically starter, a DC motor 38 is driven.

On the other hand, when the engine is manually started, a starter knob 82 is held, pulling a starter rope 80. If so, a reel 78 rotates, and the turning force is transmitted to the starter pulley 32 via a claw member 86, thus the crankshaft 20 is rotated. Afterward, the starter pulley 32 and the reel 78 are separated.
