Title: Electrostatic latent image developer
Inventor: OTA MITSURU
IPC: G03G9/097
Filed: 1995-01-31
Abstract: PURPOSE: To record a high picture quality image by incorporating fine particles subjected to surface treatment with silicone and hydrophobic treatment to prevent transfer omission from occurring while suppressing fogging to the utmost. CONSTITUTION: T his electrostatic latent image developer contains a toner, a fluidity imparting agent, an abrasive and the fine particles subjected to surface treatment with the silicone and hydrophobic treatment and containing >=5% silicone. The hydrophobic treated fine particles are preferably constituted of titanium oxide. The titanium oxide fine particles allow a magnetic toner stuck to the surface of a photoreceptor to conduct smooth transfer from the surface of the photoreceptor to a recording medium at the time of recording the image and then, transfer omission is surely prevented.  When the content of silicone in the hydrophobic treated titanium oxide fine particles is <5%, the toner is hardly released from the surface of the photoreceptor to generate transfer omission and at the time of >=15%, the characteristic of the titanium oxide fine particles is deteriorated with the increased characteristic of silicone.

Title: Ion beam process method and focus ion beam device
Inventor: ONISHI TAKESHI
IPC: H01J37/317
Filed: 1989-02-17
Abstract: PURPOSE:To obtain a high speed and a good processing form by converting the relation of the beam diameter d and the height of the difference in level h from h>=d to h<<d as the depth of the process hole increases, and controlling the amount of reattachment of sputtering particles to the side wall of the process hole. CONSTITUTION:At the initial phase of the process, the process is promoted on condition that the depth of the process hole h >= the diameter of the process hole d, and at the time when the process progresses and the aspect ratio (h/d) is made more than 0.5, for example, the beams 1 are swept on condition that h<<d. As a result, the amount of the attachment of sputter particles to the side wall of the process hole is little, and a good form of process can be carried out at a high speed. Or, the beam deflection is carried out to make the locus of the focused ion beams to scan on the sample crossing square to the normal line of the side wall of the process hole closest to the beam radiation point and making the crossing point closer to the side wall. Consequently, the attachment of the sputter particles to the side wall of the process hole can be reduced.
