SOLUTION: In this load controller of a tractor controlled so as to raise a working machine when detected size of engine load becomes larger than a previously set value, when raising output demand of the working machine is made at a frequency of a definite value or above, speed change position i...

PROBLEM TO BE SOLVED: To avoid a feeling of incompatibility given to a driver by stopping while keeping a designated inter-vehicle distance by means of keeping the braking force of a braking device in the increasing state, in the event when an anti-lock brake control means becomes operating condition in the course of deceleration in the condition of running on a low friction coefficient road surfa...

PROBLEM TO BE SOLVED: To stably supply a braking force for braking. SOLUTION: A vehicle braking force controller receives information concerning a downhill road, calculates a regeneratable energy value on the downhill road, determines an energy value recoverd on the downhill road according to the storage value of an energy storing means 15 and the information concerning the downhill road, so as to...

PROBLEM TO BE SOLVED: To control a hybrid vehicle by understanding the charged state of a battery more precisely. SOLUTION: Charged capacity of a battery is calculated by temporally integrating for charging and discharging currents to the battery. Then, a first charging rate is calculated as the ratio of the current charged capacity to the given initial capacity of the battery, and a second one is...

PROBLEM TO BE SOLVED: To prevent regenerative braking force from changing suddenly when the shifting of a shift lever of a transmission to a shift position as N-range is completed. SOLUTION: Under normal conditions, a braking controller 52 computes target regenerative braking force Frgft for a front wheel and target regenerative braking force Frgrt for a rear wheel, so that the regenerative brakin...

PROBLEM TO BE SOLVED: To provide an easily unsealable packaging bag and a packing- packaging apparatus therefor, which prevents the packaging bag from peeling off and contents from leaking out at the time of handling. SOLUTION: Edges of both of an inner film and an outer film form a superposed portion F3 of both the films, and a fold-back part F2 folded back so that the edge of the inner film is i...

PROBLEM TO BE SOLVED: To readily and inexpensively prepare a water-repellent and oil-repellent antistaining membrane which is formed by coating a specific coating layer formed on a substrate body with a water-repellent membrane, thus shows increased impregnation, supporting and holding properties of the water-repellent membrane. SOLUTION: This membrane comprises a substrate body made of a transpar...

PURPOSE: To provide a device for feeding a web which does not require a braking device, and can feed a band-form film at a specified speed. CONSTITUTION: A fourth driving motor 40 is linked to a web film 15, and a band-shaped film 16 is fed out by rotating the film 15 in a specified direction an guided to a bag-making device 18. By this method, the web film 15 rotates following the rotating speed ...

A passive infrared sensor uses two detectors having elements of different configurations such that each element outputs a respective frequency when an object moves in front of it. Based on the presence of two frequencies with similar peak and/or slope characteristics, a motion signal is output to, e.g., activate an alarm. In another embodiment the detectors have plural elements with the elements o...
