Title: Pretreatment of adsorber for seawater uranium revovery
Inventor: OZAWA YOSHIHIRO
IPC: C22B60/02
Filed: 1978-04-19
Abstract: PURPOSE: A magnetic uranium adsorber is, before seawater contact, trapped by a high-gradient magnetic separator, and then dispersed into seawater, thereby to enhance the recorvery ratio of the magnetic adsorber to about 100%.  
     CONSTITUTION: A Ti-Fe based complex magnetic adsorber is prepared by mixing ferrous and titanium solutions with alkaline solution to produce a magnetic adsorber precipitate. The precipitate is air dried, crushed, screened to obtain 20 to 40 μm, which is dispersed into water and trapped by a high-gradient magnetic separator. The separator is demagnetized to release the magnetic adsorber, which is fed into seawater as the adsorber in seawater U recovery plant. As shown in the figure, such treated magnetic granule recovery is about 100% as A, whereas a magnetic grain not treated by the high-gradient magnetic separator is trapped about 90% as B, and the rest 10% is lost.

Title: Coin receiving/paying device
Inventor: MINAMI MASANORI
IPC: G07D9/00
Filed: 1990-02-28
Abstract: PURPOSE:To eliminate a foreign matter at the time when a coin is thrown into a receiving port simultaneously with the foreign matter by providing a movable plate having a smaller cavity than the smallest coin diameter on a side plate of a coin separating part having a coin separating means. CONSTITUTION:A foreign matter gate 5 has a cavity 18, and this cavity 18 is smaller than the diameter of a coin. In such a state, when a foreign matter and a coin are thrown in, a feeder 3 rotates in order to separate and carry the coin, and in this case, the foreign matter being smaller than the diameter of the coin drops down to the outside of the feeder 3 from the cavity 18 of the foreign matter gate 5. Also, when it is ended to separate and carry the coin, the foreign matter gate 5 is driven by a motor 6, the lower part of the feeder 3 is opened, a cavity being larger than the maximum diameter of the coin is made, and from this part, a foreign matter whose diameter is larger than the coin is eliminated to the outside of the feeder 3. In such a way, faults such as a jam, an erroneous discrimination, remaining behind, etc., in a coin discriminating part are prevented.

Title: Method for tracking particle from visualized image
Inventor: HAKOZAKI JIYOUYUU
IPC: G01P13/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To analyze a flow more accurately. SOLUTION: Particles are put in a flow and a series of images are taken in a very short period. A target particle 4 is set in the image of time 1, and the target particle 4 is related to a nearby particle within a specified range. The specified range of the target particle 4 is overlaid on the image of time 2. Out of the particles of time 2 present within the specified range, a particle 5' comprising such relationship as conform to, or similar to, the position relationship between the target particle 4 and the nearby particles is selected. In that case, the relationship between the target particle 4 and the nearby particle 5' is grasped, and based on such assumption as the position relationship between the target particle 4 and the nearby particle 5' does not rapidly change in a very short period, the target particle 4 having been imaged until time 2 is specified. Here, based on the position relationship between the target particle 4 and the nearby particle 5', each particle which is visually characterless is characterized, for easier specification of target particle 4.

Title: Design supporting device
Inventor: FUKUDA MITSUKO
IPC: G06F17/50
Filed: 1990-02-28
Abstract: PURPOSE:To prevent design error by generating the connection template of elements included in the second drawing information from the first drawing information and design knowledge and inspecting whether the connection relation of the respective elements in the second drawing information is correct or not by executing comparison and collation between the connection template and the second drawing information. CONSTITUTION:A connection template preparing means 5, comparing means for the connection relation, first drawing information storage device 7, design knowledge storage device 8 and second drawing information storage device 9 are provided. The first drawing information is a drawing as the base of design and the second drawing information is a drawing to be obtained from this first drawing through the process of design. For example, when a single line drawing is used for the first drawing information, the second drawing information becomes a developed connection drawing designed from those information. Therefore, the connection template can be prepared to uniquely regulate the connection relation among the respective elements in the developed connection drawing. Thus, by executing the comparison connection onto the connection relation among the correspondent elements in the real developed connection drawing, the suitability of the connection relation can be inspected.

Title: Remelting and hardening treatment of cam sliding surface
Inventor: SAGA NORIHIKO
IPC: C21D9/30
Filed: 1985-03-08
Abstract: PURPOSE:To decrease the melt droop on cam side faces by forming preliminarily steps to both ends of a cam sliding surface of a cam shaft in the stage of subjecting the cam sliding surface to a remelting and hardening treatment by a plasma torch. CONSTITUTION:The plasma torch 3 is disposed above the cam sliding surface 2 of the cam shaft 1 and the cam shaft 1 is rotated in a direction A; at the same time the cam sliding surface 2 is remelted by the arc generated by the plasma torch 3 while the plasma torch 3 is moved back and forth B in the transverse direction of the cam sliding surface 2. The cam sliding surface is then quickly cooled to form a chill hardened layer 8 having high hardness to improve the wear resistance. The steps 4 are preliminarily provided to both ends of the cam sliding surface 2 in this case and black skin layers 5 in these parts are beforehand removed. The molten metal on the cam sliding surface generated by the arc of the plasma torch enters the steps 4 and and does not form the droop and therefore the ends of the sliding surface 2 which is remelted and hardened are prevented from from being pinholed by the gaseous CO to be generated as a result of the reaction between the droop and the black skin layers 5. The wear resistance of the cam sliding surface 2 is thus improved.
