Title: Steering mechanism of traveling transmission
Inventor: HIDAKA SHIGEMI
IPC: B60K17/356
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To gradually increase a difference in speed between left and right travel crawlers when the turning angle of a round type steering handle increases in size by changing the speed ratio of a left and right traveling device based on the rotational operation angle of the round type steering handle for operating a turning HST continuously variable shift mechanism. SOLUTION: A travel HST continuously variable shift mechanism is operated by a transmission lever and a turning HST continuously variable shift mechanism is operated by a round type steering handle. Then, the speed ratio of a left and right traveling device is changed based on the rotation steering angle of the round type steering handle. Also, as shown in the drawing, as the rotational angle of the round type steering handle is larger, a difference in speed between left and right crawlers becomes larger. Thus, when the rotational angle of the round type steering handle increases in size for turning, a difference in speed between the left and right traveling crawlers is gradually increased, a turning radius is reduced according to the steering angle of the round type steering handle and a turning angle conforming to the feeling of an operator is provided.

Inventor: NEGI SHIGEO
IPC: H02P29/00
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To obtain smooth speed command, current and torque with respect to the change in speed command input by converting speed command input to the speed command of trapezoid +S shape by adding restrictions with a trapezoidal accelerator command and controlling the current applied to a motor in response to the deviation from actual speed. SOLUTION: An interval of acceleration, where an acceleration command of an unit step is added for each sampling cycle becomes an S-shaped speed command, and an interval restricted by the maximum acceleration command becomes a trapezoidal leg portion speed command. Then the speed command pattern is output from a converter 5 as a speed command 1, a current applied to the motor is controlled, in response to the deviation from the true speed signal from a speed command signal 1 and speed measuring means 8 by motor control means 7 so as to obtain a speed pattern almost equal to that of the speed command 1. Also similarly, deceleration pattern is also abstained. In this way, smooth speed command, current and torque can be obtained with respect to changes in speed command input with simple configuration and calculations.

IPC: G03G15/09
Filed: 1987-10-07
Abstract: PURPOSE:To facilitate the increase of the charged electrostatic charging quantity of a developer by preventing a developer carrying member from traversing the fluidized bed of the developer. CONSTITUTION:A developer T close to a developing roller 5 in the fluidized bed 17 is magnetically restrained and is pushed up toward a magnetic blade 11 by rotation of the developing roller 5 and is inverted and flows down and is moved upward again in the position of a magnetic pole 9c by the rotating force of the developing roller 5 and passes the same process and is circulated in the fluidized bed 17 by convection. During this convection, the developer T is charged by friction due to rotation of the developing roll 5 or rubbing between developer particles, and its electrostatic-charging quantity is increased and held. Since the developer in the fluidized bed 17 is moved up to a part under a line l, the developer T which is led from the bottom of a vessel 1 to a point P by a rod material 27 and has a small-charged electrostatic charging quantity is taken into the fluidized bed 17. Thus, the electrostatic charging quantity of the developer T in the fluidized bed 17 is not reduced because an agitating rod 23 and the rod material 27 do not traverse the fluidized bed 17.

Title: Damping device
Inventor: YUKITA NOBUTAKA
IPC: F16F15/02
Filed: 1989-09-29
Abstract: PURPOSE:To set a resonance frequency area in a specified region by installing a weight movably relatively to a damped body such as a pipe line, holding the weight while sandwiching it by elastic bodies whose elastic coefficients are variable at the both side thereof, and providing a member which adjusts pre-compression rate of a spring on an end of the elastic body. CONSTITUTION:When a pipe line P as a damped body oscillates, a weight 3 is relatively moved in an axial direction to expand and contract springs 4, 5 on both sides thereof. The oscillations of the pipe line P are eliminated and suppressed by elastic force and mass of the weight 3. Plastic deformation members 6, 7 are expanded and contracted similarly by the relative movement of the weight 3 and repeat plastic deformation. Oscillation energy is therefore changed into heat, consumed, whereby the oscillation is attenuated. The position of a spring receiving flange 8 on a supporting bar 2 is changed in an axial direction by a nut 9. The spring constant is varied by varying compression rate of variable pitch springs 4, 5. Then resonance frequency area is varied to correspond each frequency of the damped body.
