Title: Cooling device for valve seat ring arranged into cylinder head for internal combustion engine
Inventor: MIHIYAERU BEERU
IPC: F02F1/40
Filed: 1989-08-28
Abstract: PURPOSE: To effectively use an existing lubricating oil circulating path to realize maximum heat transmission and uniform cooling by, in an annular passage surrounding a valve seat ring, making a supply duct and a discharge duct approach to each other to form an opening. CONSTITUTION: In a cylinder head 1, a valve seat ring 5 is arranged in each air exhaust passage 4, and the valve seat ring 5 is surrounded by an annular passage 6. Further, the annular passage 6 comprises a supply duct 7 and a discharge duct 8, which approach to each other to hold a projection 16 and are bored in openings 9 and 10. Therefore, lubricating oil supplied from the supply duct 7 is exhausted from the discharge duct 8 after the lubricating oil circulates in the annular passage 6. As a consequence, the valve seat ring 5 can be uniformly cooled by the lubrication oil as a coolant.

Inventor: MATSUDA MASAYOSHI
IPC: H01F30/00
Filed: 1988-09-01
Abstract: PURPOSE:To discriminate displays irrespective of the depth of a recess, the angle of a ceiling face, the irregularity in the quantity of light, etc., by forming recesses of part number, data number on the surface embossed with unevenness of several microns on the top face of a plastic sheathed case. CONSTITUTION:A transformer body is inserted into a sheathing case 1 of plastic molded form opened at one end and embossed on its top face with unevenness of several microns. A part number 3 or a data number 4 is punched on the top face of the case 1 in recessed state. This employs a principle of reading a symbol due to the difference of the intensity of the reflected light of the surface 2 of the case and the intensity of the reflected light of the recess 3. The top face 2 is formed to be uneven of several microns, i.e., embossed face 5. Thus, the light 13 irradiating the top face 2 is reflected at random on the uneven face of the embossed face 5 or absorbed, and not reflected externally as it is. As a result, the level of the intensity of the reflected light of the face 2 is reduced, and the intensities of the reflected lights of the face 2 at any angles can be equalized.
