Title: Cleaning apparatus
IPC: B08B1/04
Filed: 1992-03-27
Abstract: PURPOSE:To perform efficiently cleaning. CONSTITUTION:When blades 51 of a turbine are pinched between rotating blushes 21a and 21b and a motor 15 is rotated, the rotating blushes 21a and 21b take out stain by rotating each other in the opposite direction while they are brought into contact with the both faces of the blades 51 and the both faces of the blades 51 are pushed lower side by the rotating force of the rotating blushes 21a and 21b. Cleaning and movement can be simultaneously performed by adjusting the moving speed by an operator. When a cleaning apparatus main body is set vertical to the surface of the blade 51 and the rotating blushes 21a and 21b are pushed on the surface and the motor 15 is rotated, the rotating blushes 21a and 21b are rotated reversely each other and a force for movement is offset and movement does not occur.

IPC: G11B7/135
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To restrain reflection of the incident light by a reflection preventive film, and to improve utilization efficiency of the light by forming a film having a light reflection preventive effect on a surface of a solid immersion lens. SOLUTION: A film 2 having a light reflection preventive effect is formed on a surface (a semispherical surface and a plane) of a solid immersion lens 1. As the simplest constitution of the film 2 having such a reflection preventive effect, a required process is only to arrange a film having a thickness (d) for satisfying an expression (nd=λ/4) to a wave length λ of a light beam LB by using a material of a refractive index (n) smaller than a refractive index of the solid immersion lens 1. Or a multilayer film structure by properly combining a material having a refractive index higher than the solid immersion lens 1 and a material having a low refractive index may also be acceptable.  By using a conductive material on the outermost surface of the reflection preventive film 2, that is, in the case of a single layer structure, a material of the film itself is made conductive, and in the case of a multilayer structure, the outermost layer is made conductive to be put in earth electric potential to avoid electrification of the solid immersion lens 1 to prevent adhesion of dust and dirt.

Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To obtain a partially transparent or translucent window by hardware technique. SOLUTION: This is actualized by using a kind of chromakey technique. In concrete, two display memories (106, 108) are prepared and a display is made normally on the basis of data from one memory 106, but when a pixel of a specific color is read out of this memory, the pixel is displayed by being switched to data read out of the other memory 108.

Title: Ion implantation
Inventor: OSAKI SABURO
IPC: H01J37/317
Filed: 1986-04-30
Abstract: PURPOSE:To perform ion implantation uniformly and with good accuracy even when the incidence angle of the beam becomes large by changing scanning frequency in accordance with an irradiated position by the ion beam in an ion implantation device of an ion beam scanning type. CONSTITUTION:An ion beam 10 from an ion source 1 is scanned by deflection electrodes 3 in the X direction and deflection electrodes 4 in the Y direction to irradiate a sample substrate 6 for implanting impurity ions. In this case, according to the irradiated position on the sample substrate 6 scanning frequency at least either in the horizontal direction or in the vertical direction is altered by the scanner 5. Thus the change of ion distribution depending on the distance to the surface of the sample substrate 6 covered by the ion beam 10 is compensated. It is therefore made possible to perform uniform ion implantation on the overall surface. Accordingly, even when impurities are implanted on the side wall of the sample substrate 6 having a grooved construction, ion implantation can be performed with uniformity and good controllability.
