Title: Containing method of radioactive contaminant and container therefor
Inventor: SAKATANI TADATSUGU
IPC: G21F5/002
Filed: 1994-07-15
Abstract: PURPOSE:To enhance the cooling efficiency, the radioactivity shielding performance, and the impact resistance by containing a plurality of radioactive contaminants within a container while sectioning and integrating the container and the radioactive contaminants by filling a molten metal between them and solidifying. CONSTITUTION:Rectangular tubular frames 2 are supported by coupling frames 2a in a stainless steel container body 1A and the space part 3a between the container body 1A and the frame 2 is filled with molten metal, e.g. aluminum, having high thermal conductivity which is then cooled and solidified thus integrating the body 1A and the frame 2 through a cast metal layer M. A radioactive contaminant X, e.g. a spent fuel assembly, is then loaded into each frame 2 and an upper case 1B is applied to the body 1A and seal welded thereto. Subsequently, the space in the case 1B is filled with He gas thus forming a container P for radioactive contaminant. Since the decay-heat of the contaminant X is transmitted through the cast metal layer M to the container 1, heat radiation performance is enhanced. Radioactivity shielding performance is also enhanced because the metal layer M shields radioactivity.

Title: Diversity receiver
Inventor: SHIMIZU ISAO
IPC: H04B7/26
Filed: 1987-07-03
Abstract: PURPOSE:To reduce the influence of interference from an interleaved channel by adding a changeover switch and a level comparator for detecting the occurrence of the interleaved channel interference in addition to conventional diversity operation. CONSTITUTION:When there is not the interleaved channel interference, a computing element 9 outputs 1 and the changeover switch 10 is connected to k-0. The demodulation output of a receiver with the high envelope of a received wave selected by the comparator 3 and a changeover switch 4 appears at a demodulation output terminal 11. If the received signal from an antenna 1a has the interleaved channel interference, the output (g) of a comparator 7a for the demodulation output becomes 1 and a switch 8b for the demodulation output closes the circuit to pass a signal h'. Further, the output (n) of the computing element 9 becomes 0, so the changeover switch 10 outputs a signal (m) to the terminal 11. Even if the receiver of one system is affected by the interleaved channel interference, the probability that the receivers of other systems are not affected by the interference is high.

Abstract: PURPOSE:To automatically supply a recording medium such as a thin paper and eliminate non-printable areas, by transferring the recording member being printed, at a pitch synchronous with the feed of the medium by a roller. CONSTITUTION:A gear 29 is moved toward and engaged with a gear 31 or a gear 32 according to the rotating direction of a motor 25, and transmits motive power.

The gear 32 is connected to a roller 20 by a shaft 37, and is so rotated that the roller 20 is rotated at a paper-feeding pitch equal to that on the side of a printing part 5. When the motor 25 is rotated in the direction of an arrow 38, the gear 29 is moved in the direction of an arrow 39 to rotate the gear 31 counterclockwise, thereby rotating the roller 15 forward and reversely. When the motor 25 is rotated in the direction opposite to the arrow 38, the gear 29 is moved in the direction opposite to the arrow 39 to rotate the gear 32 clockwise, thereby driving the roller 20 in the direction for feeding a recording medium 6.
