Title: Water treatment device for breeding aquarium fish
Inventor: HIRAMATSU TERUO
IPC: C02F9/00
Filed: 1991-10-25
Abstract: PURPOSE:To clear water quality or a water tank for breeding and also to stably protect environment of water quality by eliminating protein-based putrefaction especially caused from excretions of fish and residual feed. CONSTITUTION:Both an ion exchange treatment part 10 and a fluidization electrolytic treatment part 12 are connected in a series closed circuit shape by a passage 6 of water flow for breeding in a water tank 5 for breeding aquarium fish. The ion exchange treatment part 10 is arranged in the upstream side of flow in the fluidization electrolytic treatment part 12 while keeping the water tank 5 as a standard. Porous ion exchangers 14 having porous inorganic mineral as a base body are held in the ion exchange treatment part 10. The admixture of a plurality of granular inorganic substances 17 different in dielectric constant is held in the fluidization electrolytic treatment part 12 so that they are rubbed and collide with each other. Thereby organic waste is previously removed by the ion exchange treatment part 10 and deactivation of the fluidization electrolytic part is prevented. Buffer action is held in a water region by the ion exchangers 14.

Filed: 1992-11-17
Abstract: PURPOSE:To transmit any fault to an operator without mixing it with the faulty operation of the other equipment. CONSTITUTION:When either of a blower 12, filters 11 and 14, and an exhauster 17 is faulty, it is indicated on a display 24 located at a position opposed to an operator in a work space 10, and it is also indicated that either of these devices is faulty.

Title: Rotary seal bearing
Inventor: TANIGUCHI YOSHINOBU
IPC: F16J15/40
Filed: 1990-11-15
Abstract: PURPOSE:To prevent the splashing due to centrifugal force and stabilize the sealing performance for a long period by sealing the magnetic fluid having a viscosity of 0.5 Pascal sec. or more by the magnetic force between a magnetic pole and a magnet in the space surrounded by a bearing an a bearing housing. CONSTITUTION:On the opposed surfaces of housings 14 and 15 for both the surfaces of a flange 13, the gaps having each dimension h1, h2 are formed from magnetic poles 23, 24 and the flange 13. The magnetic fluid 37 is sealed in the gap, and the viscosity of the magnetic fluid 37 is over 0.5 Pascal sec. On the outer peripheral side of the flange 13, a ring shaped magnet 28 is fixed, nipped between the magnetic poles 23 and 24, and N and S poles are arranged on the same poles on the sides where the magnetic poles 23 and 24 are opposed. With this constitution, the magnetic fluid 37 is sealed in the gap between both the magnetic poles 23 and 24 the flange 13 by the magnetic force generated from the magnet 28. Since the magnetic fluid 37 possesses the high viscosity as described in the above, splashing and leak are prevented nearly perfectly, and the stable sealing performance can be obtained in the use for a long period.

Title: Rotary head device and magnetic recording and reproducing device
Inventor: MATSUURA KENJI
IPC: G11B15/61
Filed: 1989-11-27
Abstract: PURPOSE:To keep a floating amt. of a magnetic tape from a rotary drum to approximately the same extent even at a different relative scanning speed between a magnetic head and the magnetic tape by adding a means for changing the rotating direction of the rotary drum. CONSTITUTION:When the relative scanning speed of the magnetic head 5 to the magnetic tape 1 is low, the traveling direction of the tape 1 is the same as the scanning direction of the head 5, and when the relative scanning speed of the head 5 is high, the rotating direction of the rotary drum 2 is changed by a rotating direction changeover circuit 33 in order to reverse the scanning direction of the head 5 while the traveling direction of the tape remains unchanged. Consequently, when the relative scanning speed of the head 5 is high, since tape tension is relatively high by reversing the rotating direction of the drum 2, the tape 1 is hardly floated up. On the other hand, when the relative scanning speed of the head 5 is low, the floating amt. of the tape 1 is not altered as before. Consequently, variations in the floating amt. of the tape 1 due to a revolving speed change of the drum 2 can be diminished.
