Title: Ionic current measuring system for ion implanting device
Inventor: SAKAI KATSUHIKO
IPC: H01J37/317
Filed: 1989-03-08
Abstract: PURPOSE:To prevent malfunction by making necessary provision so that all components associated with an ionic current measuring system within the vacuum chamber of an implantation chamber have positive potential with respect to the chamber. CONSTITUTION:Positive potential is applied to an ionic current measuring system, that is, to a faraday cylinder 3, a disk 4 and other parts making up a faraday cup, within an ion implanting device so that they have positive potential with respect to a vacuum chamber 2 which has the earth potential. As a result, within the vacuum chamber, the ionic current measuring system has the highest potential and thus electrons that have leaked from the ionic current measuring system are drawn back to the ionic current measuring system. Placing a power supply 10 for voltage application between an electrode in the vacuum chamber and an ionic ampere meter 6 makes it easy to handle the ampere meter 6 and electronic circuitry associated with the ionic current measuring system at the earth potential level. This arrangement can prevent electron leakage without modifying the configuration of the conventional ion implanting chamber and ensures more accurate ionic current measurement.

Title: Recovery of uranium from phosphate rock
Inventor: HAMASHIMA KATSUYA
IPC: C22B60/02
Filed: 1983-03-31
Abstract: PURPOSE:To separate and recover uranium in the preparation of phosphate from phosphate rock, economically, in high recovery, by the co-precipitation process using an aluminum salt as a co-precipitation agent. CONSTITUTION:A properly pretreated phosphate rock is treated with sulfuric acid to obtain calcium sulfate and phosphoric acid. The produced calcium sulfate is separated from the phosphoric acid, and the resultant concentrated phosphoric acid is diluted with water, added with about 1%, based on the phosphate rock, of an aluminum salt (e.g. aluminum nitrate) as a co-precipitation agent, and the pH of the system is adjusted to 3-7 with an alkali agent. The produced precipitate containing uranium is separated by filtration, and uranium is recovered therefrom by a proper method. The filtrate left after the separation of the uranium-containing precipitate is added with an alkali agent to produce a phosphate, which is taken out of the system in the form of a solid.

Title: Bidirectional optical transmission device and bidirectional transmission system using it
Inventor: IMOTO KATSUYUKI
IPC: H04B10/2507
Filed: 1984-03-23
Abstract: PURPOSE:To facilitate bidirectional communication with one optical fiber and lights different in wavelength by forming interference film filters, which have optical coupling and branching functions, on rod lenses and providing these rod lenses in the up side and the down side. CONSTITUTION:Interference film filters F23 and 24 and similar filters 28 and 29 are attached to rod lenses 22 and 27, which are provided in both ends of an optical fiber 7, through spacers 25 and 30. The F23 permits the light having a wavelength lambda1 to transmit through, but reflects lights having wavelengths lambda2 and lambda3, and the F24 permits lights having wavelengths lambda1 and lambda2 to transmit through, but reflects the light having the wavelength lambda3, and the F28 permits lights having wavelengths lambda1 and lambda3 to transmit through, but reflects the light having the wavelength lambda2, and F29 permits the light having the wavelength lambda3 to transmit through, but reflects lights having wavelengths lambda1 and lambda2. For example, the light having the wavelength lambda1 from a semiconductor laser LD1 passes a lens 2, the F23, the spacer 25, the F24, the rod lens 22, the fiber 7, the rod lens 27, the F28, and the spacer 30 and is reflected on the F29 and is made incident on an optical fiber 9 in the condensation position. Similarly, the light having the wavelength lambda2 from a laser LD1'' is made incident on an optical fiber 35, and the light having the wavelength lambda3 from a laser LD1' is made incident on an optical fiber 33. Thus, bidirectional communication with wavelengths lambda1, lambda2, and lambda3 is performed easily by only one optical fiber 7.
