Title: Water treatment apparatus
Inventor: TAMARU RIE
IPC: C02F9/00
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To obtain a proper water quantity at the time of use by adjusting water to be supplied to a pan from a treatment apparatus corresponding to the input of water quantity previously transmitted from a means of automatically measuring water quantity and storing a proper amount of water in an empty container. SOLUTION: This water treatment apparatus 1 comprises a setting part 18 disposed outside a main body through which a user can select the water quantity based on his necessity at the time of use of water and a flow rate meter 17 disposed in a flow route inside the main body which can calculate the water flow rate. The setting part 18 is operated interlockingly with a control apparatus 12 in the inside of the main body and the transmitted input of the water quantity is sent as a signal to the flow rate meter 17 through a cable. The flow rate meter 17 enables water to flow in a defined quantity which is sent from the control apparatus 12. Due to such a structure, a user can easily take water in a necessary amount in a container without using a measuring cup, or the like.  Water to be supplied to a pan from a treatment apparatus is increased or decreased corresponding to the previously given quantity of water and a desired amount of water can be stored in, for example, an empty PET bottle.

Title: Fuel assembly
Inventor: YAMAUCHI KOKI
IPC: G21C3/328
Filed: 1990-10-05
Abstract: PURPOSE:To enable decrement of void reactivity coefficient without changing water-to-fuel-volume-ratio by making an arrangement of fuel rods and water rods to be of a triangular grid shape by making a rods number ratio of the water rods to a total rods number to be more than 10%. CONSTITUTION:Fuel rods 3 are arranged in a shape of a regular triangle grid in a square channel box CB1. In this case, when a vertical arrangement pitch of the fuel rods 3 is (a), a horizontal arrangement pitch becomes 3<1/2> a/2 = 0.87a. Accordingly, when a ratio of the vertical and horizontal rods numbers is made to be an integer of around 1 to 0.87, the arrangement shape is made to be of an almost square shape and the fuel rods are arranged in the shape of triangular grid shape, the fuel rods 3 can be very effectively arranged. In this occasion, a column number in case of 10 rows becomes 10divided by 0.87 = 11.49, that is, 11 columns, and therewith a moderator flow area can be reduced by around 5%. Also, when number ratio of the water rods WL2 is made to more than 10%, fuel assembly can be intended to be much more enriched. In this case, the WL2 have to be arranged so that moderator and fuel in the fuel assembly may be much evenly distributed.

Filed: 1994-10-04
Abstract: PURPOSE: To carry out the aeration agitation stably and efficiently by providing a draft tube to prevent the bubbles which have been circulated from the bottom of a tank from penetrating into a water passage of a screw. CONSTITUTION: A screw type aeration machine 6 is disposed opposed to a draft tube 3 provided in a treatment tank 1 and a suction port 3b at the upper end of the draft tube 3 and the lower end surface of a screw 62 are disposed substantially in the same plane.

Title: Apparatus and method for measuring distance and capable of estimating weather condition
Inventor: YOSHIDA MASATO
IPC: G01S17/93
Filed: 1994-10-31
Abstract: PURPOSE: To estimate weather conditions in a compact structure with low manufacturing costs. CONSTITUTION: A collection signal-generating means 38 regularly switches and selectively outputs a target distance collection signal or a meteorological distance collection signal. A target distance-collecting means 40 when receiving the target distance collection signal feeds to a detecting means 34 a reduction instruction to lower the detecting sensitivity in a small range of measuring time. At the same time, the collecting means 40 fetches the distance obtained in this state as a target distance. A meteorological distance-collecting means 42 when receiving the meteorological distance collection signal impresses to the detecting means 34 a non-reduction instruction to make the detecting sensitivity almost constant irrespective of the length of the measuring time, and moreover fetches the distance detected in this state as a meteorological distance.  A weather-estimating means 46 estimates weather conditions based on either or both of the detecting level and meteorological distance, or both of the detecting level and meteorological distance and the target distance.
