Title: Manufacture of high density iron sintered body
Inventor: HAYASHI KOJI
IPC: B22F1/00
Filed: 1989-10-24
Abstract: PURPOSE:To obtain a sintered body having closeness of >=98% relative density by making carbon content in raw material iron powder used to powder metallurgical method the specific value or less. CONSTITUTION:Iron powder having <=0.01wt.% carbon content is compacted, and the obtd. compacted body is sintered. By this method, the iron sintered body having >=98% relative density of the sintered body, is obtd. What the closeness is obstructed with various kinds of gases generated or existing in isolated void in the sintered body, lies in the fact that the gas pressure in the isolated void becomes surface stress in the isolated void (driving force of shrinkage of the void) or higher. As the surface stress of void of 3mu radius is about 1.2MPa at 1400 deg.C, if the gas pressure in the isolated void is <=1.2MPa, this isolated void is shrunk and the closeness is not obstructed. Then, what the CO gas pressure equibrium to the content of carbon and oxygen in the iron becomes 1.2MPa at 1400 deg.C is 0.01wt.% carbon content in the iron. Therefore, in order to develop the closeness, the carbon content in the iron has to be <=0.01wt.%.

Abstract: PURPOSE:To easily vary a variable power range, to simplify the lens barrel of the lens and to prevent the whole zoom lens system from becoming larger in size by replacing a partial lens group of the nearest lens group to an object side among plural lens groups, with other lens group and varying a variable power range of the whole system.

By moving the second and the third lens groups in the direction as indicated with an arrow, variable power extending from a wide angle end to a telephoto end, and also, by moving the second lens group II on the optical axis, focusing is executed. In such a state, by using the lens group AI as a lens group A1 for lens replacement, and replacing it with other lens group B1 so that an image point position to an infinity object becomes roughly constant, the variable power range of the whole zoom lens is varied. In such a way, the variable power range can be varied easily.

Title: Optical recording medium and optical recording body as well as recording method and reading method thereof
Inventor: HANEDA TOSHIO
IPC: G11B7/246
Filed: 1988-10-31
Abstract: PURPOSE:To increase the recording quantity per unit area by multiple recording to unit optical scanning lines by laminating plural kinds of films essentially consisting of dyes which have the light absorption wavelengths within a range from a visible light region to a near IR region and are respectively different in the absorption wavelengths. CONSTITUTION:The films 12, 13 essentially consisting of plural kinds of the dyes which are different in the light absorption wavelength by >=100nm are successively formed and laminated on a transparent substrate 11 with guide grooves and such substrate is used as the optical recording medium 14. The medium layer 14 is irradiated with the light formed by synthesizing plural kinds of laser light rays of the wavelengths coinciding with the absorption wavelengths of the respective dyes which are the essential components of the medium constituting layers 12, 13. The light which is different in the wavelength from the absorption wavelengths of the dyes which are the essential component is, therefore, transmitted through each of the respective layers constituting the optical recording medium 14 and only the light of the equal wavelength is selectively absorbed. Heat generation is simultaeously caused by light-heat conversion to urge the discoloration in this section. The information modulated to the irradiating light is thus recorded. Simultaneous recording of plural kinds of the information in the same section or in the separate section apart by as much as the image formation distance of the synthesized light, i.e. as much as the asymmetric distance of the optical axis is possible and the simultaneous reading is possible in this way and, therefore, the recording density is increased plural-folds.
