Title: Anti-lock brake controller
Inventor: TSUTSUMI JUNJI
IPC: B60T8/66
Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To eliminate a shortage of pressure increase and prevent the fluctuation of deceleration of a car body surely so as to enable good anti-lock brake control by providing an upper limit value compensation means which compensates an upper limit value of cylinder pressure for braking and compensating the upper limit value of cylinder pressure for braking in accordance with a pressure increase time stored value in one braking cycle. SOLUTION: In a controller CR which inputs output signals of wheel speed sensors 3FL to 3R when a vehicle is driven, car body speed gradient is calculated based on wheel speed detected values by wheel speed computing circuits 15FL to 15R, and car body speed is estimated based on the wheel speed detected values. Furthermore, pressure of cylinders for braking 2FL to 2R is estimated based on master cylinder pressure obtained by pressure sensors 13A, 13B which detect master cylinder pressure and control signals for actuators 6FL to 6R. An upper limit value of cylinder pressure for braking is set based on car body speed gradient, and the upper limit value of cylinder pressure for braking is compensated in accordance with the number of times of pressure increase signals in one braking cycle.

Title: Burning preventer for transfer clutch
Inventor: SUZUKI HOSEI
IPC: B60K23/08
Filed: 1985-11-29
Abstract: PURPOSE:To prevent burning of a transfer clutch by providing an accelerator pedal switch to be turned on with a small accelerator opening and disabling switching over to four wheel driving if said accelerator pedal switch is turned off. CONSTITUTION:Even upon occurrence of a slip to close a relay contact 32a or upon switching of a manual changeover switch 21 to the four wheel drive side, a H-level output is fed to an O gate 41 if an accelerator pedal is stepped and a switch 35 is turned off and a logic circuit 40 will keep non-conducting condition of a transistor 45. Consequently, it is never switched from the two wheel drive to the four wheel drive. Turning on of the switch 35 while shifting the accelerator pedal to the low opening side will cause switching to the four wheel drive. Since the slipping speed and the driving force of a transfer clutch are low, it will cause low impact resulting in prevention of burning of the clutch due to abrupt engagement.

IPC: B02C13/28
Filed: 1992-09-14
Abstract: PURPOSE: To improve the efficiency of crushing system and to decrease the number of crushing processes by specifying the min. moment given to lump by primary impact force and increasing the moment given to the lump by secondary impact force by specific times that by the primary impact force. CONSTITUTION: The rock and the ore lump are coarsely crushed into small chips by applying the primary impact force with a primary crushing rotor 1 and are thrown toward secondary crushing rotors 2, 3 by the rotation of the primary crushing rotor 1. Because the secondary crushing rotors 2, 3 are constituted so as to be rotated synchronously with the primary crushing rotor 1, the small chips collide vertically with the impact reflecting surfaces of the secondary crushing rotors 2, 3 to be crushed into fine particles. The min. moment given to the lump by the primary impact force is controlled to 180 kgm/sec and the moment given to the lump by the secondary impact force is controlled to 0.3-70 times the moment given to the lump by the primary impact force. As a result, the crushing efficiency by the secondary crushing rotors 2, 3 is increased.
