Title: Automatic focusing device for video camera
Inventor: OOTA JUNJI
IPC: G02B7/28
Filed: 1986-01-16
Abstract: PURPOSE:To simplify the whole mechanism of the titled device by constituting a means for driving a lens so as to displace a fine distance stepwise. CONSTITUTION:A microcomputer 22 stores a focusing signal value at the position of a focusing lens 10-4 and then moves the lens 10-4 in an optional direction by a prescribed unit. The focusing position before the movement is compared with that after movement, and when the compared result is negative, the lens 10-4 is moved in the reverse direction, and in case of positive value, moves the lens 10-4 further in the same direction. When the compared result is turned from a positive value to a negative value, the computer 22 stores the contents so that the succeeding moving direction of the lens 10-4 is reversed. The lens 10-4 is displaced reversely from the preceding movement at the rate of once to several frames and the focusing positions before and after the displacement are compared. When the difference of the focusing signals is a prescribed value or more, operation is returned to the original operation. Since automatic focusing can be attained only by a single lens driving system under said constitution, the mechanism can be simplified.

IPC: F23N5/24
Filed: 1983-01-21
Abstract: PURPOSE:To contrive the safety during the failure of a timer by a method wherein a timer for prepurging time serves also as a timer for safety time. CONSTITUTION:When a sequence including prepurging function is intended, if an input terminal 4 goes to the ''1'' level, because of an input terminal 6 being at the ''0'' level, the clock pulse of an input terminal 2 is inputted through NAND gates 35 and 37 to a T flip-flop 13 so as to be frequency-divided at T flip-flops 13-23. When an output Q23 goes to the ''1'' level, an RS flip-flop 26 is set and consequently a terminal 11 goes to the ''1'' level, resulting in starting ignition operation. A differentiation circuit 27 issues a ''1'' pulse so as to reset the T flip-flops 13-23 in order to start a safety time by releasing the resets of the T flip-flops 13-23. When a sequence including no prepurging function is intended, because of the input terminal 6 being at the ''1'' level, the high-frequency clock pulses of an oscillator 34 is inputted at the point A. resulting in instantaneously bringing the output Q23 to the ''1'' level and consequently accomplishing ignition operation. Because a timer for prepurging serves also as a timer for safety, the failure of the timer for safety can be checked, resulting in enabling to contrive the safety.

Title: Method and device for treating waste water containing radioactive material
Inventor: SUYAMA TAKAZO
IPC: G21F9/06
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To drastically reduce the amount of adsorbent to be disposed per treatment waste water by introducing the waste water into an adsorbent-filling tower for adsorbing and eliminating a radioactive substance, introducing an elimination/reproduction liquid when the adsorption capacity decreases for repeating detachment/reproduction, and disposing the adsorbent whose adsorption capacity has decreased. SOLUTION: Four stages of adsorbent-filling towers 4-1-4-4 are connected in series, where the first stage is used for treating waste water, the second and third ones are used for condensing the radioactive substance, and the fourth one is used for a final adsorbent-filling tower. The waste water containing a radioactive substance where pH is close to neutral is introduced into the filling tower 4-1 where an absorbent 4a-1 is filled, and the radioactive substance and metals are adsorbed and eliminated and are unloaded as treated waste water W2. When adsorption approaches a balanced state and an adsorption capacity decreases, the introduction of non-treated water W1 is stopped and the adsorbent 4a-1 is reproduced. Similarly, adsorbents 41-2 and 4a-3 are reproduced.  The amount of adsorbent to be disposed can be reduced to 1/1000 as compared with a case where the waste water containing a radioactive substance is treated by one adsorbent-filling tower. The number of filling towers can be changed according to treatment conditions.
