Title: Full water detector
Inventor: KOBAYASHI SUKEMITSU
IPC: F04D9/04
Filed: 1982-04-02
Abstract: PURPOSE:To simplify constructon of a detector, by introducing the atmospheric air into a vacuum chamber to break a vacuum when a float is lifted and closely attached to a valve seat in case of filling water fully by a vacuum pump and utilizing the lift of the float to detect the full water. CONSTITUTION:When water is empty in a main unit 1, a float 3 is placed on a float support 2, and a suction hole 11 and an air hole 13 provided to a hollow valve shaft 4 are both positioned in a vacuum chamber 12. Under this condition, if air is sucked from a connection hole 10 by action of a vacuum pump to increase a vacuum degree in the unit 1, water flows into from the bottom part of the unit 1 to lift the float 3. Then if the unit 1 is filled fully with water, the float 3 is closely attached to a valve seat 5 to block outflow of the water to a side of the vacuum pump. While also the shaft 4 is lifted to expose the hole 11 above a bush 7, and the atmospheric air is introduced into the chamber 12 to break a vacuum. Further at this time, a microswitch 9 is turned ON to detect a full water condition.

Title: Water turbine runner
Inventor: MIMORI KIYOYASU
IPC: F03B3/12
Filed: 1979-05-04
Abstract: PURPOSE: To prevent a runner from being damaged by a method wherein a crown or a shrouded ring is thickened gradually toward the part of joint of a blade and thereby the vibration stress concentrating on the part is reduced in the runner of a pump and a water turbine.  
     CONSTITUTION: In a turbine wheel having large capacity and operated at a high speed, a crown 1 and a shrouded ring 3 vibrate strongly in the axial direction by hydraulic pulsations, whereby the vibration stress occurs intensively in and around the joint of a blade. In order to prevent this intensive occurence of the vibration stress in the region, the thickness of the joint of the crown 1 and the shrouded ring 3 with the blade and its vicinity on the surface of the inner periphery of a runner is enlarged, while the thickness of the part from there to the vicinity of the center of a water inlet port 4 is lessened gradually. In addition, it is also possible that another thick part 64 is provided on the outer periphery of the runner, while the central part of the water inlet port 4 where the stress is small is thinned and filled with a damping material 84, thereby augmenting the damping effect.

Title: Regulated dc power supply unit
Inventor: HIRAYAMA KOUZOU
IPC: H02M7/06
Filed: 1978-05-10
Abstract: PURPOSE: To accomplish accurate regulation of positive and negative voltage even in unbalanced load by means of a coupling winding mounted to a smoothing choke oil of a power unit adapted to supply positive and negative voltage equal in the absolute valve.  
     CONSTITUTION: A positive DC voltage is obtained from the second winding B of an output transformer 3 in a converter through diodes 4A and 5A and a choke coil 6C and a negative DC voltage through diodes 4B and 5B and a choke oil 6D. The choke coils 6C and 6D are provided with respective coupling windings 10C and 10D to be connected together so that current flowing through one choke coil generates electromotive force in the other coil. With such an arrangement, when loads 8A and 8B are unbalanced, increase of the current in one choke coil causes a drop in the current in the other choke coil to make up for the imbalance. Thus, the outputs V 1  and V 2  can be regulated to be invariably equal in the absolute value.

Title: Fault detector for neutron detector
Inventor: IWASAKI TOMOHIKO
IPC: G01T3/00
Filed: 1983-03-31
Abstract: PURPOSE:To achieve an easy discovery of abnormality by a method wherein a normalized constant determined in the division of a mean signal by a detector signal is multiplied by the subsequent detector signal and a computed value for comparison determined in the division of the absolute value of the difference between the resultant normalized signal and the mean value by the mean signal is compared with a rated neutron detector signal. CONSTITUTION:Detector signals fed from a plurality of neutron detectors 1 with an average circuit 12 through a cable core 9 are averaged to determine a mean signal. A normalized constant setting adjustment circuit 15 divides the mean signal by a single detector signal to determine and hold a normalization constant for normalizing the detector signal to a mean signal and multiplies a detector signal fed subsequently by the normalization constant to output the results as a normalization signal. A comparator circuit 16 determines an absolute value of the difference between the mean signal and the normalization signal from the normalization constant setting adjustment circuit 15 and divides the absolute value by the mean signal to determine a computed value for comparison, a value normalized to a rated neutron detector signal output. The computed value is compared with the allowable range of a neutron detector output with respect to the rated neutron detector signal preset.
