Title: Surface reforming method for magnetic head sliding surface and magnetic head
Inventor: MAMIYA SATORU
IPC: G11B5/133
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of head characteristics by implanting N2 <+> ions or N<+> ions into a magnetic head sliding surface, thereby reforming the front surface of the magnetic head sliding surface. SOLUTION: The magnetic head sliding surface 2 is formed atop a magnetic head 1 and a gap 3 is formed in its central part. A magnetic tape travels on the magnetic head sliding surface 2, by which the writing of information or the reading out of the information to or from the magnetic tape is made possible. The N2 <+> ions are implanted into the magnetic head sliding surface 2 in about 10<16> to 10<18> pieces/cm<2> to a depth of 800 to 3000 Å. The N2 <+> ions or N<+> ions are accelerated and are implanted into the magnetic head sliding surface, by which the inside of the magnetic head sliding surface and near the magnetic head sliding surface is nitrided, the hardness of the magnetic head sliding surface is enhanced and work hardened layers are decreased.  Wear is lessened by enhancing the hardness of the magnetic head sliding surface with which the traveling tapes comes into contact for a long time.

Title: Vehicle braking device
Inventor: SHINNO HIROAKI
IPC: B60L50/16
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To realize a cooperative control without using a conventional cooperation type control system valve. SOLUTION: A brake ECU 40 carries out a cooperative control of a regenerative braking and a hydraulic braking depending on the detecting signal of a leg-power sensor 41. The hydraulic braking has a master cylinder (M/C) 51; the first check valve 52 to maintain the pressure of a wheel cylinder (W/C) more than M/C pressure, and a brake fluid feeding part 60 to control the brake pressure fed to W/C by the control signal from the brake ECU 40. When a brake pedal BP is depressed, a liquid pressure braking force (the minimum brake force) generated by the lowermost M/C pressure as the liquid pressure braking force by the existence of the first check valve 52 comes to operate, and as a result, the maximum value of the regerative braking force is made as the value the vehicle braking force minus the minimum braking force.  As a result, the cooperative control can be carried out without using a conventional cooperation type valve, and by the existence of the first check valve 52, the failsafe can be obtained more profitably than in the conventional way.
