Title: Water cleaning device
Inventor: TSUCHIYA SHOICHI
IPC: B01D29/62
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To set the part, in which the volume of a channel per unit length in the channel direction of water flowing through the channel, is small, close to or equal to the purification treating capacity of the part in which the volume of the channel is large, in a water cleaning device with a variable channel area in a filter. SOLUTION: This water quality purification device is of such a functional structure that a water to be treated is caused to flow into a water collection part 27 (outflow part) in the center of a treating part 32 from the lateral part (inflow part) of the treating part 32 by driving a pump 58 provided in the center of the treating part 32 of a cylindrical shape and the water to be treated is purified with a charcoal 23 (filler) packed in the treating part 32. The packing of the charcoal 23 in a layer part 37 immediately near the water collection part 27 of the treating part 32 is increased, and the packing of the charcoal 23 in a layer part 38 provided outside the layer part 37 is set to be smaller than that of the layer part 37.  In addition, the packing of the charcoal 23 in a layer part 39 provided outside the layer part 38 is set to be further smaller than that of the layer part 37. Thus the sums of the surface areas of the charcoal 23 packed in the volume of the flow path per unit length in the channel direction in each of the layer parts 37-39, are almost equal.

Title: Method and device for transporting live fish
Inventor: TANABE KAZU
IPC: A01K63/02
Filed: 1988-04-27
Abstract: PURPOSE:To transport live fish at reduced equipment and operation costs by allowing fresh water taken from outside a vessel to pass through a water trough provided in the hull, and transporting the fish in the trough while it swims against the water stream. CONSTITUTION:When a vessel is cruising, fresh water outside the vessel is introduced from a water intake 3, diffused into near a uniform stream by an increasing conduit pipe, put into a water trough 2, allowed to pass through, and exhausted to outside the vessel from an exhaust hole 5 via a reducing conduit pipe 6. Because live fish generally swims against the stream, the fish accommodated in the water trough 2 does alike when a water stream is generated in the water trough 2. This allows live fish to exercise motion in optimum environment, which keeps tightened quality of the flesh. Further there is no need to refill the water stream producing energy, which accomplishes a very aconomical live fish facility. Also supply of fresh water at all times permits omission or simplification of devices for oxygen refill, water purification, water temp. adjustment, etc., to lead reduction of the facility and operation costs to a great extent.

Title: Method and device for measuring thickness of pure zirconium liner of fuel coating pipe
Inventor: TAMURA TOSHIYUKI
IPC: G01B15/02
Filed: 1982-06-22
Abstract: PURPOSE:To perform nondestructive measurement, by irradiating X rays from the inside of a coating pipe, generating the characteristic X rays of component other than zirconium among the component of zircaloy, measuring the X rays by a detector, and obtaining the thickness of a linter from the relationship with the attenuation factor of the characteristic X rays. CONSTITUTION:A liner 2 comprising pure zirconium is provided on the inner surface of a coating pipe 1 comprising a zircaloy alloy. An X ray source 3 and X ray detector 4 are arranged in the coating pipe 1. An Am-241 radiation source 6, which is provided in the X ray source 3 radiates gamma rays, excites zirconium target 7, and generates characteristic KX rays 8. The rays are irradiated on the coating pipe 1 from a radiating port 5a. Then only component elements Fe, Cr, and Ni other than zirconium in the zircaloy alloy generate characteristic X rays 9. The characteristic X rays 9 are transmitted through a liner 2 and inputted in the X ray detector 4. The characteristic X rays 9 are attenuated when they are transmitted through the liner 2. Since the relationship between the attenuation factor and the thickness of the liner is known, the attenuation factor is obtained from the output of the X ray detector 4, and the thickness of the liner is obtained from this factor.

Title: Voltage division controller for capacitor
Inventor: OKATSUCHI CHIHIRO
IPC: H01G11/00
Filed: 1992-04-24
Abstract: PURPOSE:To activate the controller effectively in the state of voltage unbalance only and to reduce power consumption when the voltage is balanced by providing a transistor(TR) conductive when a voltage across a capacitor exceeds a setting voltage so as to balance the shared voltage of each capacitor. CONSTITUTION:MOSFETs 101, 201 are respectively connected in parallel with capacitors 1, 2 connected in series and voltage division resistors 102 and 103, and 202 and 203 are connected and their divided voltage is fed respectively to gates of the MOSFETs 101, 201. In this case, the voltage division ratio by the voltage division resistors is set so that the MOSFETs start conduction when the voltage across the capacitor exceeds its rating voltage. When a voltage across an optional capacitor exceeds the setting voltage due to unbalance, the TR is conductive to discharge the charge in the capacitor so as to balance the voltage share and when the voltage across the capacitor is less than the setting voltage, the TR is nonconductive and no power loss is caused. Thus, when the capacitor is used in place of a battery, a voltage holding time is extended.
