Title: Magnetic recording medium
Inventor: KAWANA TAKAHIRO
IPC: C10N40/18
Filed: 1985-02-05
Abstract: PURPOSE:To form a protective layer capable of maintaining lubricating action for a long period and to obtain the magnetic recording medium having a small friction coefficient and having excellent durability and traveling property by depositing an extreme-pressure agent of a phosphoric ester amine salt on a ferromagnetic metallic thin film. CONSTITUTION:A ferromagnetic metallic thin film is formed on a non-magnetic carrier, and an extreme-pressure agent of a phosphoric ester amine salt is deposited on the ferromagnetic metallic thin film to form a recording medium. When metallic contact is locally generated in the boundary lubricating region, the extreme-pressure agent of a phosphoric ester amine salt to be used reacts with the metallic surface by the resulting frictional heat to form a reaction product coated film, and the friction and abrasion are prevented. A dibutyl phosphate butylamine salt can be exemplified as the extreme-pressure agent of a phosphoric ester amine salt. The extreme-pressure agent of a phosphoric ester amine salt can be prepared by adding an equivalent amt. of refined alkylamine to acidic phosphoric ester, and agitating the mixture at room temp.

Abstract: PURPOSE:To keep a working machine in optimum posture independent of the inclination of a vehicle, by making a lower link distant from an inputting shaft to be vertically movable relative to the other lower link, thereby enabling the control of the rolling of the working machine. CONSTITUTION:In case of controlling a working machine in horizontal posture independent of the lateral inclination of a vehicle 3, the inclination of the vehicle 3 is detected by a horizontal sensor. When a length corresponding to the inclination angle is detected by a stroke sensor 16, the working machine is horizontal in lateral direction and the rolling control is set neutral. Accordingly, a rolling cylinder 15 is stretched or contracted according to the detection of the inclination by the horizontal sensor to vertically turn a lower link 5 relative to the other lower link 4 of a fixed position. The level difference between the right and the left lower links 4, 5 is detected by the stroke sensor 16 and, when the detected value coincides with the target length for control, the stretching and contracting control is stopped to position the working machine in horizontal posture.

Title: Slip control device for lockup torque convertor
Inventor: MURASUGI TAKU
IPC: F16H61/14
Filed: 1986-02-05
Abstract: PURPOSE:To make a gear change shock small by reducing line pressure when there is occurring a drop in the pressure of a lockup control chamber because of slip control at the time of a gear change. CONSTITUTION:Slip control for a transmission causes a drop in lockup control chamber pressure PL, but a pressure switch 36 is turned ON, thereby reducing an input to a reversing amplifier 34 to a lower level, controlling a solenoid 31a and causing a solenoid valve 31 to open a drain port 30. Consequently, there occurs a drop in throttle pressure directed from the throttle circuit 42 to the pressure regulator valve 41, and line pressure also gives a drop. The capacity of a frictional element to be actuated on the line pressure at the time of a gear change is thereby caused to decrease and peak torque an inertia phase can be made small, thereby enabling the reduction of a gear change shock.
