Title: Optical pickup
Inventor: KATO MASAYUKI
IPC: G11B7/135
Filed: 1986-12-18
Abstract: PURPOSE:To obtain the titled pickup with light weight and small size coping with the change in wavelength of an optical conductor laser by using 1st and 2nd grating lenses so as to cross in axial symmetry divergent lights from a coherent light source and focusing the result to one point of an optical disk medium by a 3rd grating lens. CONSTITUTION:A signal light reflected in an optical dism medium M is retured through the forward path and part of the signal line is reflected by a partial transparent mirror 3 as shown in broken lines. The reflected signal light becomes a radiation wave spread at the outside of the optical axis, reflected again in a ring mirror 4, reaches a ring zone at the outside of the 1st grating lens 1, focused by the 3rd grating lens 5 in optical axis symmetry, is made incident in a photodetector D and detected. Thus, the signal light from the optical disk medium M is led to the photodetector D via the 2nd and 3rd lenses 2, 5 and since the fluctuation of wavelength is compensated by the lens system 2, 5 similarly as the 1st and 2nd lens systems 1, 2, the aberration and out of focus of the signal on the photodetector D is suppressed.

Title: Method of surface smoothening
Inventor: OYOSHI KEIJI
IPC: C03C21/00
Filed: 1989-11-18
Abstract: PURPOSE:To repair a structure of scratches, etc., of several hundreds nm thickness or less, which has been regarded difficult, and to obtain the surface of a material having extremely high smoothness by injecting metal and/or nonmetal ions in the polished surface of the material. CONSTITUTION:The surface of a material (e.g. glass to be used for photomask substrate) is polished to obtain such a surface having minute scratches which can be repaired by the following ion injection process, and then metal and/or nonmetal ions are injected thereto. Thereby, the surface is finished to have an extremely high smoothness as above mentioned. The ion injection is preferably performed by selecting the energy and angle of injection so that the injection distance of the ions (depth from the surface of the body) is 1/10-1000 times as the depth of structural defect in the smoothened surface. The energy of ion injection is given by 1KeV-10MeV accelerated energy. Thus, the glass substrate after ion injection can be used for a photomask substrate suitable for super-fine patterning of semiconductor process.

Title: Flat membrane type filter
Inventor: NISHIDA YUJI
IPC: B01D65/02
Filed: 1993-11-05
Abstract: PURPOSE:To effectively perform membrane washing by an air scrubbing method by vertically installing flat filter membrane cells having through-holes in a liquid to be treated in a tank and arranging diffuser pipes below the flat filter membrane cells. CONSTITUTION:An original liquid feeding pamp 23 is driven to feed an original liquid into a liquid to be treated in a tank 21, and a vacuum pump 25 is driven to generate differential pressure between the membranes, allowing filtration to be effected. Simultaneously with the original liquid treatment, a blower 28 is driven every fixed period of time to diffuse air into the original liquid from diffuser pipes 26, and the gas-liquid mixed flow of the diffused air and the original liquid rises between flat filter membrane cells 1. While the gas-liquid mixed flow rises along the flat filter membranes 1, a part of the rising flow is passed through the through-holes of the flat filter membrane cells 1 to make the rising flow turbulent. Since vibration acts on the flat filter membrane cells 1 with the making turbulent and the flat filter membrane cells 1 are easily deflected owing to the through-holes, the vibration of the flat filter membrane cells 1 is accelerated. Therefore, materials onto stuck the membrane surface are effectively peeled and removed.

Title: Ink-jet recording
Inventor: SAKAI YASUSABURO
IPC: C09D11/00
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To improve water resistance and weatherability and a water-based ink to the same level as that of a plate printing ink since a water-based ink having a composition composed of a water-soluble dye and water provides stable ink discharge due to physical properties (surface tension and viscosity) suitable for ink-jet but a defect of weak water resistance has been unable to be solved when a water-soluble dye is used as an ink colorant. SOLUTION: Ink-jet recording is carried out by using a water-based ink obtained by dissolving a leuco sulfuric ester alkali metal salt of quinone type insoluble organic coloring matter and ink dots on a material to be recorded are provided with light energy to change the organic coloring matter into an insoluble coloring matter. Consequently the durability (water resistance, light resistance and heat resistance) of printing ink is improved to the same level as that of a plate printing ink.
