Title: Controller for agitator of reaction tank
Inventor: IBATO SHINICHI
IPC: G05B11/32
Filed: 1979-04-16
Abstract: PURPOSE:To unify the reaction and agitation of a mixed liquid in a reaction tank by a method wherein the maximum deviation is obtained from the mean value of the measured value of reacting conditions acquired from a plurality of reacting condition detectors installed to the tank and the number of revolution of an agitator is controlled so that the deviation be kept within allowable value. CONSTITUTION:Temperature detectors 5-8 for detecting reacting conditions are properly disposed into a mixed liquid 4 in a reaction tank 1 provided with an agitator 2 and rotary blades 3. Measured temperature signals 9-12 measured by means of these detectors are read to an arithmetic unit 13 every sampling time. Liquid-level detecting signals 15 from a liquid-level detector 14 for the mixed liquid are also inputted to the arithmetic unit 13. Mean value of temperature measured is obtained by means of the arithmetic unit 13, deviation is computed every each detector 5-8, the maximum deviation value is acquired, and the aimed number of revolution is secured. The aimed number of revolution is sent to an analog regulator 17 as command setting signals 16 from the arithmetic unit 13, converted into operation signals 18 and put out to a driving signal transducer 19. The transducer 19 drives the agitator 2 at the desired number of revolution by using an agitator driving power source 20.

Abstract: PURPOSE: To perform the recovery of uranium present in the sea water by utilizing the force of tide current by the procedure in which a floating tank provided with a desorption liquid tank, a regenerating liquid tank, a water-washing tank for U- adsorbent, and then by circulating an U-adsorbent through the sea water and the aforesaid tanks by the force of tide current.  
     CONSTITUTION: The upper part of the floating tank 10 is provided with the desorption liquid tank 2, the regenerating liquid tank 3, and the water-washing tank 4 for uranium(U) adsorbent, and the U-adsorption belt with a number of blades 9 is rotated endlessly while being circulated through the sea water and a series of the aforesaid tanks 2, 3, and 4 by using the pulley 1 and the rotator 17. In this case, since the floating tank 10 is moored to the sea bottom by the mooring chain 11, the tide current collids with the blades 9 and thereby the adsorption belt 8 is rotated. The adsorbent, composed of the binary hydrate Ti-Fe oxides, is then treated with (NH 4 ) 2 CO 3 , Na 2 CO 3 , etc., to desorp U in the desorption liquid tank 2, and then substances other than U are desorped by a mineral acid, e.g., hydrochloric acid, etc., in the regenerating liquid tank 3 to regenerate the adsorbent. The adsorbent is washed with water and reused for U adsorption.

Title: Water heating and its device
Inventor: MIYAHARA KINGO
IPC: F24H1/20
Filed: 1988-02-27
Abstract: PURPOSE:To raise the temperature of heated water in a short time and keep the temperature of the exhaust gas always at a low temperature by jetting the water in a water reservoir which is pumped up by a rotating body out into a hot air chamber through which hot air flows freely through a flowing water guide body and making the water hot by the heat exchanging action by direct contact of the water with hot air. CONSTITUTION:A certain fixed amount of water pumped up by a rotating body 109 is discharged with a power toward the inner face of a flowing water guide body 102 which is provided on the outside of the rotating body 109, and part of the discharged water flows down along the inside surface of the flowing water guide body 102 into a water reservoir 101 through a lower open section. On the other hand the rest of the water is jetted out with a power in the radial direction into a hot air chamber 119 to make contact with the flowing hot air. As a result the jetted water becomes soon heated water by the direct heat exchange action of the water and the flowing hot air in the hot air chamber 119, and than the water falls into the water reservoir from both ends of a cover 118 which covers the hot air chamber 119 and then it is again pumped up by the rotating body. Because of this repeated heat exchanging action the water becomes high temperature hot water rapidly.

Title: Injection of grouting agent into two-layered ground
Inventor: MIZOGUCHI AKIMOTO
IPC: E02D3/12
Filed: 1980-04-09
Abstract: PURPOSE: To favorably improve the second stratum of a two-layered ground inhibiting a grouting agent going up to the first stratum by a method in which a self- setting filler familialized with the first stratum is packed into a large diameter pit drilled down to the boundary between the first and second strate, and then a grouting agent is injected into the second stratum through an injection hole drilled in the filler.  
     CONSTITUTION: A pit 3 of a larger diameter than that of an injection hole 5 is drilled in the first stratum 1 (e.g., banked soil) until it reaches the boundary between the first stratum and the second stratum. Then, a self-setting filler 4 familialized with the first stratum (e.g., cement-clay grout) is paced in the pit 3. And, after the filler 4 has hardened, the injection hole 5 is frilled in the second stratum 2 through the filler 4. Then, a grouting agent is injected into the stratum 2 through an injection pipe 6 inserted into the hole 5, where the grouting agent is completely sealed up separately from the stratum 1 by means of a packer 7 and the filler 4. Thus, no injection of the grouting agent into the stratum 1 takes place. After the completion of the injection work, the pipe 6 is removed and then the filler 4 is again packed in the hole 5.

Title: Roll for rolling mill
Inventor: HASHIMOTO RITSUO
IPC: B21B27/08
Filed: 1984-03-12
Abstract: PURPOSE:To prevent generation of a heat crown with the small diameter of rolling mill rolls and under high pressure and to obtain a rolled product having high accuracy by sealing a heat medium into the rolls. CONSTITUTION:A cavity 12 is provided in the form of a hole in the longitudinal direction at the rotating center of a work roll 1 and steam 13 as a heat medium is vacuum-sealed into the cavity 12. The steam 13 evaporates at the point in the axial central part of the roll 11 where the temp. increases to a high degree. The generated steam 13a flows to the point at the end of the roll 11 where the temp. decreases owing to a difference in pressure which arises naturally. The steam is cooled and condensed at said point, thus forming a liquid film 13b. The film 13b is circulated by the centrifugal force of the roll 1 to the central part of the work roll 13 where the film 13b is thin by repeating evaporation and condensation in the cavity 12. The quantity of the heat transmitted in the axial direction of the roll 13 is thus increased and the temp. difference is decreased.

Abstract: PROBLEM TO BE SOLVED: To withdraw an illegal card by a reader and to make detectable an illegal action such as the talking-out of withdrawn illegal card. SOLUTION: In detecting that an inserted prepaid card is illegally processed, a reader 10 fetches in the card, prepares an illegal information on the illegal card and transmits the prepared information to a repeater 20. The repeater 20 counts up the number of illegal cards detected based upon the reception of illegal information and stores the count value together with the illegal information. Each illegal card taken out from the reader 10 is inserted into an illegal card storage device 30. The device 30 inquires the repeater 20, and when the illegal information of the inserted card is stored in the repeater 20, stores the information, counts up the volume of illegal information and stores the volume. At the end of the system or the like, the repeater 20 compares the stored count value with the count value stored in the device 30, and when both the count value do not coincide with each other, judges the generation of an illegal action such as the taking-out of a recovered card and informs of the judged result.
