Title: Method and apparatus for adsorbing uranium
Inventor: FUKUNAGA TOSHIHIRO
IPC: B01D15/00
Filed: 1978-09-05
Abstract: PURPOSE: To enhance uranium adsorption efficiency by packing an uranium adsorbent of 0.1W5mm diameter in a bed at a packing density of 0.7W1g/ml and a specified thickness; covering the bed with a netlike material or the like; and dipping the covered bed in sea water.  
     CONSTITUTION: A known uranium adsorbent of 0.1W5mm diameter such as titanic acid is packed in adsorption bed structure 1 consisting of frame 2, upper and lower support frames 4, 4, etc. and having opening part 3 at a packing density of 0.7W1 g/ml and a thickness of 3W30mm. Part 3 is covered with polyethylene fibers, stainless steel porous plates, etc. A plurality of structures 1 are then fixed in layers at spaces of 1W10cm and dipped in sea water. In case of below 0.1mm diameter the adsorbent clogs the netlike cover, and above 5mm diameter prevents penetration of sea water. Thus, uranium can efficiently be recovered from sea water.

Filed: 1989-04-28
Abstract: PURPOSE:To obtain an oscillation circuit which rapidly reacts with a change in the brightness of the sunlight at the brightness of the sunlight by utilizing the oscillation circuit with which a solar battery acts as a sensor. CONSTITUTION:The voltage of the solar battery 1 is increased by the brightness of the sunlight and the oscillation circuit operates to change the color of a liquid crystal. Namely, the solar battery 1 acts as the optical sensor and generates the voltage by the brightness of the sunlight. The CR oscillation circuit 3 operates to darken the color of a liquid crystal panel when the voltage exceeds a specified voltage. The voltage of the solar battery 1 drops conversely when the sunlight darkens. The oscillation of the CR oscillation circuit is then stopped and the color of the liquid crystal panel is thinned. The need for the switching from the outside is eliminated in this way and since the sunglasses react sensitively with the brightness of the sunlight, the effective use thereof in a place where the brightness and darkness ratio is high is possible.

Title: Can receiving device
Inventor: IIOKA TOSHIAKI
IPC: B21D51/26
Filed: 1982-06-28
Abstract: PURPOSE:To prevent buckling of the bottom of a can made of thin material at the time of sealing of the cover by surrounding the periphery of a central panel supported by a spring with an elastic body having larger spring constant than the spring. CONSTITUTION:When sealing a cover 4 to the opening of a can, a coil spring 13 is compressed by axial load, and a central panel 11 is lowered. The periphery 26 of the bottom 2 of a metallic can 1 comes into contact with a peripheral support 12 and presses it. At this time, as the coil spring 13 is smaller in spring constant than the elastic part that constitutes the peripheral support 12, axial load is mainly received by the peripheral support 12. Accordingly, the axial load applied to a convex part 2a is relatively small, and on the other hand, the axial load applied to a peripheral part 2b is relatively large. However, as its bending moment is small, relatively thin material can be used for the bottom 2.
