Title: Composite plating method
Inventor: KONDOU YUKIHIRO
IPC: C25D15/02
Filed: 1981-10-30
Abstract: PURPOSE:To obtain a contact with high reliability and high capacity by a composite plating method for depositing WC particles in a Pd-Ni alloy plating layer by specifying pH and current density during plating. CONSTITUTION:Plating is carried out in a composite plating bath prepared by dispersing WC particles in a Pd-Ni alloy plating soln. at <=1.0A/dm<2> current density while keeping the bath at 8.2-9.4pH. At <8.2pH the suspended WC is not deposited in a Pd-Ni alloy layer, and at >9.4pH WC is deposited at ununiform density and a contact with high reliability and high capacity is not obtd. At >1.0A/dm<2> current density deposited WC becomes a porous state to the Pd- Ni alloy layer, so the bonding strength is reduced and it is difficult to obtain a contact with desirable performance. By increasing the current density at the constant pH or raising the pH at the constant current density, the amount of WC deposited in the Pd-Ni alloy layer is increased and the percentage of Pd in the alloy layer is liable to increase.

Filed: 1989-07-05
Abstract: PURPOSE:To identify each track at the time of reproducing by changing the height of a light beam in the axial direction of a rotary drum each time an optical tape is once scanned by the light beam. CONSTITUTION:By positioning respective pickups 8 and 8 so that a distance between the beam to be emitted from the pickups 8 and 8 and a rotary shaft can be made different, the height of the beams to be reflected by a reflection prism 4 is respectively made different in the rotary axial direction of a reflecting point.

IPC: F24H9/00
Filed: 1986-07-25
Abstract: PURPOSE:To enable a hot stable water temperature to be attained by a method wherein a water supplying pipe and a hot water supplying pipe are installed at an upper part of a can body in such a way that they are allowed to communicate with a spacing, and a water supplying conduit having its lower end closed and having a bar-ring like opening directed toward a projection at a position oppositely facing toward a top point of the projection part directed toward an outer barrel having a corrugated shape of an inner barrel is arranged within the water supplying pipe. CONSTITUTION:Supplied water is guided into a can body through a water supplying pipe 19 arranged within a water supplying pipe 11 and flows out through a bar-ring like opening of the water supplying pipe 19. Water flowed out of the opening is directed toward a top point of projecting part of an inner barrel 13. A water supplying speed is decreased, the water is directed toward an upper recessed part and a lower recessed part, resulting in that the speed is further decreased. Due to this fact, a speed of water dispersed upwardly is sufficiently decreased and the water is not directly fed toward a hot water feeding pipe 12, and a stable hot temperature water can be attained. The fed water is rapidly fed in a circumferential direction along a recessed groove, resulting in that a uniform heating can be carried out at each of the portions of the can body.

Title: Magnetic disk
Inventor: NAKAZAWA FUMIKI
IPC: G11B5/82
Filed: 1987-07-15
Abstract: PURPOSE:To obtain a magnetic disk having high durability by constituting a carbon layer of 2 layers of carbon layers which are different in hardness and forming the 1st layer on a chromium layer to the hardness higher than the hardness of the 2nd layer to be formed thereon. CONSTITUTION:Two layers of the carbon films which are different in hardness are formed by changing the vacuum degree at the time of sputtering. The carbon for the 1st layer is sputtered to 200Angstrom by setting the vacuum degree at the time of the sputtering to 9X10<-4>Torr for the above-mentioned purpose. The vacuum degree is then dropped down to 8X10<-3>Torr and the carbon of the 2nd layer is sputtered to 200Angstrom . Then, the carbon of the 1st layer is made into the hard carbon layer by the sputtering in the high vacuum. The carbon of the 2nd layer is made into the carbon layer softer than the 1st layer, since the vacuum degree for said layer is lower than the 1st layer. The durability between a head and the magnetic disk is thereby greatly improved.
