Title: Fountain device
Inventor: KODAMA AKIRA
IPC: B05B17/08
Filed: 1989-03-27
Abstract: PURPOSE:To obtain the fountain device which is extremely aesthetic during non-operation by constituting a nozzle, which is concentrically provided with ejection ports, of a stationary part and a movable part which can be vertically displaced with respect thereto and connecting the movable part to a float. CONSTITUTION:The movable part 5 of the nozzle 1 is vertically displaceably mounted to the stationary part 4. The stationary part 4 and the movable part 5 have the concentrical ejection ports 4a, 5a and the movable part 5 is connected to a float 6. Fountains 3 in the form of the water building up to a prescribed height are formed when the pressure water fed by a pump P is ejected from the ejection port 4a of the stationary part 4 and is then ejected from the ejection port 5a of the movable part 5. When the water level varies, the movable part 5 follows up the varying levels and moves vertically together with the float 6 and, therefore, the submerging depth H of the port 5a does not change and even if the water level changes, the form of the fountains 3 does not change. Since the float 6 is merely required to float the movable part 5 alone, the smaller size is necessitated and the unsightly appearance even during non operation is obviated.

Title: Epicyclic roller clutch reduction gear
Inventor: KANEDA KOUICHI
IPC: F16H13/08
Filed: 1980-06-05
Abstract: PURPOSE: To permit the smooth transmission of power with lesser amount of noise and vibration by providing plural epicyclic roolers between a conical wheel at the tip of the main driving shaft and the conical inner surface of the body case.  
     CONSTITUTION: When each of three epicyclic rollers 12 turns by a frictional transmission caused by the rotation of a conical wheel 6 at the tip of the main deriving shaft 5, each epicyclic roller 12 intends to fit with the conical face of the conical wheel 6, whereby leading it to go up to the top (the right-handed base end in Fig.) of the conical wheel 6. However, since the peripheral face of the conical wheel 6 and the conical inner surface of the body case are so designed that the width of the conical annular peripheral aperture S is gradually slightly widened toward the top, each epicyclic roller 12 becomes strongly and frictionally contacted with the conical wheel 6 toward the narrower widthwise direction of the conical annular spherical aperture S. Thus, exact rolling with less sliding can be attained by a strong frictional transmission all the time.

Abstract: PURPOSE:To reduce construction cost and running cost as well by installing a water trickle support member vertically in an insulation ice making chamber, forcing ice making water to flow down to said water trickle support member, taking in cold open air, and freezing said ice making water to the water trickle support member. CONSTITUTION:A support member designed to suspend and support a water trickle support member 6 which forces ice making water to flow down, holder 7 designed to suspend and hold the support member, and a water supply device 8 designed to supply ice making water, are installed inside an ice chamber where an insulation material is laid out on a side wall 1, a ceiling 2, and a bottom 3. At the same time when the operation starts, the ice making water sufficiently cooled by a cold water reservoir or the like is supplied by a pump 14 to a water supply device 8 by way of an ice making water pipe 13 through a water supply pipe 15. The water exchanges heat with the cold open air at a temperature of 0 deg.C taken from an open air intake port during the time when it flows down the water tackle support member 6 so that icicles 16 may grow near the bottom of the water trickle support member 6. It is, therefore, possible to eliminate the need for the compression and transportation of snow and loading of ice, thereby reducing running cost, and installation cost as well.

Title: Method of estimating life of centrifugal pump
Inventor: YAMAMOTO YOICHI
IPC: F04D1/00
Filed: 1995-03-31
Abstract: PURPOSE: To estimate the life accurately by expressing the drop of the shutoff pressure at the time of performance deterioration of a centrifugal pump and the increase of the pressure drop coefficient as the function of time passage, in the case of performing the estimation of life by the specification of discharge pressure and discharge flow rate of the centrifugal pump. CONSTITUTION: When the pump has become unable to discharge required flow Qx at the time of working pressure at use place being Px, it is judged that the pump has come to the end of its life. The (discharge pressure)-(discharge flow Q) property of the centrifugal pump can be approximated by the expression of P=PC-α.Q<2> . But, PC is shutoff pressure (P at the time of Q=0), and αis pressure drop coefficient. If the performance of the pump deteriorates, this PC drops as compared with its initial condition, while αincreases, so both can be expressed as the function of passage of time; t. Since the discharge pressure P of the pump and the flow Q are obtained by the estimation of actual machine, the life is estimated by adopting several data and executing regression analysis thereby obtaining PC and α, in P=A.Q<2> +B.
