Title: Water cooled disc brake
Inventor: OKOCHI YUKIO
IPC: F16D65/84
Filed: 1992-01-13
Abstract: PURPOSE:To provide a water-cooled disc brake simple in structure by providing a cooling water passage for permitting cooling water to reach the surface of a friction member while the flow of cooling water is limited. CONSTITUTION:While during the non-braking operation, a switching valve 70 is closed to prevent cooling water from flowing into a porous body 28, during the braking operation, the air temperature in a cooling water passage is raised by frictional heat generated when the frictional surfaces 30 of the respective materials 18 of pads 14, 16 are pressed to the frictional surface 12 of a rotor 10, and a ball 72 is pushed up from a valve seat 74 against the pressure of cooling water by the pressure of thermal expanded air to open the switching valve 70. Accordingly, the cooling water flows into the passage 56 little by little from a conduit 66 to ooze out on the surface of the porous body 28. Accordingly, the temperature of the friction material 18 is lowered, and the oozed that the rotor 10 and the pads 14,16 are cooled. When the temperature of the pads 14,16 is lowered, the switching valve is closed to check inflow of cooling water. Thus, the structure can be simplified as compared with the case of cooling water circulation.

Title: Method for forming artificial diamond by vapor deposition
Inventor: KIKUCHI NORIBUMI
IPC: C30B25/02
Filed: 1984-02-14
Abstract: PURPOSE:To form artificial diamond at a high rate of vapor deposition by irradiating UV light to the surface of a base body heated in the flow of the gaseous mixture composed of hydrogen and hydrocarbon. CONSTITUTION:UV light having 150-350nm wavelength is irradiated to the surface of a base body which is placed in the flow of the gaseous mixture composed of hydrogen and hydrocarbon under 0.1-300Torr atmospheric pressure and is heated to 300-1,200 deg.C. The rate of forming the diamond by vapor deposition on the surface of the base body decreases and the method is not industrial if the atmospheric pressure is below 0.1Torr. A graphite phase precipitates if the pressure exceeds 300Torr. The rate of forming the diamond by vapor deposition on the surface of the base body is too low if the heating temp. of the base body surface is below 300 deg.C and the precipitation of a graphite phase is liable to arise when the temp. exceeds 1,200 deg.C. The result is better as the wavelength of UV light is shorter but it is industrially difficult to obtain the wavelength below 150nm and the formation of the diamond is difficult at the wavelength exceeding 350nm.
