Title: Water level controller of deaerator
Inventor: NONAKA SETSUO
IPC: F01K9/00
Filed: 1984-10-05
Abstract: PURPOSE:To prevent run-out of a condensate pump or the condensate boosting pump of a nuclear plant caused by an excessive opening of a condensate flow rate regulating valve by providing a means for restricting flow rate of condensate by use of a setter which has been adjusted to set up flow rate of condensate to a specified value under the maximum allowable discharge flow rate. CONSTITUTION:In a water level controlling system of a deaerator, an output signal of a deaerator water level transmitter 24 is subjected to comparison plus integrating calculation in a deaerator water level regulating gauge 6, and to addition or subtraction to or from an output signal of a feed water flow rate transmitter 25 to obtain a signal concerning the required feed water flow rate of the deaerator. The signal is then sent to a selector 66 used for restricting a condensate flow rate and the selector 66 compares this signal with a signal which is equivalent to a rated flow rate inputted via switches 70, 72 and 74 to be closed in accordance with the number of condensate pumps in operation and via a primary delay unit 67 and duly corresponding to said number of condensate pumps in operation. The selector then selects one signal of less flow rate from the flow rate signals and sends the selected one to a condensate flow rate regulating gauge 68 as a flow rate setting signal. A control signal which is in accordance with a deviation between this signal and the measuring signal of a condensate flow rate transmitter 22 is then computed in said gauge 68 to control a condensate flow rate regulating valve 21.

IPC: A47B47/02
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a frame structure of a working table for easily attaching a support and a connecting rod in assembling the frame. SOLUTION: A support 2 consists of a wide part and a narrow part in the front/rear direction, and supports 2 are disposed with their narrow parts facing each other.

Title: Alloy type temperature fuse
Inventor: IWAMOTO YOSHISHIRO
IPC: H01H85/56
Filed: 1989-08-11
Abstract: PURPOSE:To evade deformation such as waving and twisting of a fuse element even if it is unevenly heated by generation heat at the time of ordinary operation of an equipment by using a substance having a composition causing no crystal transformation of low melting point soluble alloy at a temperature between a heating temperature at the time ordinary operation and a temperature at the time of an operation stop of the equipment. CONSTITUTION:In the temperature range from a heating temperature at an ordinary operation time to a temperature at the time of an operation stop time, a low melting point soluble alloy having a stable crystal type and no crystal transformation is used for a fuse element. For instance, no crystal transformation is caused when an alloy consisting of tin: 48wt.%, lead: 18wt.%, indium: 34wt.% is used for the fuse element, and a ceramic is fused for an insulated substrate, while epoxy resin is used for a resin mold layer. Thereby, even if temperature distribution is uneven, only simple crystal constitution can be taken, no twisting and waving of the fuse element can be caused.

Title: Water supplying method for water jet work
Inventor: SUZUKI TOMIO
IPC: E02D7/24
Filed: 1981-12-28
Abstract: PURPOSE:To effectively excavate various kinds of strate by a method in which a jet pump using high-pressure water from a high-pressure water supply pump is inserted into a high-pressure waterway from which the water is supplied to an excavating nozzle and excavation is made while varying the pressure and  amount of the pressure water. CONSTITUTION:When a high-pressure pump 3 is actuated, water in a water tank 1 is supplied through a suction hose 2, a jet pump 4 and a high-pressure hose 5 to an excavating nozzle 7 at the tip of a pile 6 to excavate the ground. When the ground of even low-moisture content requires a high-pressure jet, a flange 25 is pushed and the tip of the nozzle 23 is pressed on a valve seat 24, whereupon the supply of water from the suction hose 2' is stopped and high-pressure water from the nozzle pipe 22 is supplied to the excavating nozzle 7. Also, in the case of gravel layer, requiring a large amount of water, when the nozzle 23 and the valve seat 24 are sufficiently opened, high-pressure water from the nozzle 23 sucks up low-pressure water in the surrounding and thereby high-pressure water of as much as 2-3 times is sent into the high-pressure hose 5.

Title: Magnetic fluid seal device
Inventor: HIROYAMA HIROO
IPC: F16J15/40
Filed: 1985-09-25
Abstract: PURPOSE:To stabilize the sealing characteristic of a magnetic fluid seal device used in a high speed rotary machine, by feeding cooled magnetic fluid into gaps between magnetic rings and a shaft through storage chambers with the use of a cooling facility and a pump. CONSTITUTION:On the inner peripheral side of a nonmagnetic housing 2, a permanent magnet 4 is held between planer magnetic rings 3, and a shaft 1 pierces through the magnetic rings 3 at the center of the latter. Magnetic fluid 5 is applied in gaps between the magnetic rings 3 and the shaft 1. Storage chambers 6 for reserving magnetic fluid 5 are defined between the magnetic rings 3 and the nonmagnetic housing 2 on the magnetic ring 3 side at the upper and lower positions of the housing 2. Magnetic fluid which is always cooled is automatically fed into holes 11 through the storage chambers 6 by means of a cooling facility 10 and a pump 9. Therefore, an increase in temperature of magnetic fluid 5 caused by the heat of shearing friction generated by the rotation of the shaft 1 is restrained due to the heat transmission of the magnet rings 3, and substantially no lowering of sealing characteristic is caused, thereby dissipation of magnetic fluid 5 is slight.
