Title: Nuclear fuel assembly
Inventor: YOSHIDA HIDEO
IPC: G21C3/30
Filed: 1988-03-28
Abstract: PURPOSE:To prevent the failure and dislodgment of an elastic member to be caused by the load at the time of mounting and dismounting of a channel box, the oscillation of a nuclear reactor during operation and the deformation of the channel box, etc., by forming the elastic member into an inside and outside double spring structure formed by bending and forming one thin sheet to a U shape. CONSTITUTION:The elastic member 1 is made into the double spring structure consisting of the outside spring 2 and the inside spring 3 by bending and forming a sheet to the U shape. The upper part thereof constitutes respective curved parts (a) which are bored respectively with holding holes 4, 5 for insertion and holding of the lower end plugs of fuel rods 11. This elastic member 1 is interposed to the side face of a lower tie plate 12 when the upper curved parts (a) thereof are pinched and fixed by the fuel rods 11 and the lower tie plate 12. The resilience of the elastic member 1 is thereby increased and the failure by the load from the outside is decreased. The various influences that the member receives from the channel box are thus decreased. The inside spring is surely protected and the member is not dislodged in spite of the failure of the outside spring. The safety of the structure is thus improved.

Title: Control method for rotary electric machine
Inventor: NAGAYAMA KAZUTOSHI
IPC: H02P21/00
Filed: 1994-04-13
Abstract: PURPOSE:To expand the range of operating speed by adopting one of the control, which makes the magnetic flux of a magnetic field system beneath the base number of rotation constant and makes the magnetic flux reverse-proportional with respect to the number of rotation when it is higher than the base number of rotation, and the control, which adjusts the armature current and voltage so that the current ratio of the components of the voltage induced in an armature winding becomes constant. CONSTITUTION:The detected value of a rotation detector 36 is added to a speed command as the present speed in a speed detecting part 38, and the value is converted into the magnetic flux of a magnetic flux field system with an operator 39. The magnetic flux of the magnetic field system is made constant beneath the base number of rotation of a motor and made to change in reversely proportion to the number of rotation higher than the base number of rotation. The current flowing through this armature winding is obtained with an exciting current operator 40 and divided into the component in the same phase corresponding to the induced voltage of the armature winding and the component, which is perpendicular to the component in the same phase. The components are controlled with a DC-current control circuit 41 so that the ratio of the current components becomes constant. Thus, the range of the operating speed can be expanded.

Filed: 1978-06-22
Abstract: PURPOSE: To prevent the display fluctuation of the reception frequency caused by the fluctuation of the local oscillation frequency and other factors for the digital display system of the reception frequency by holding the counting result of the frequency counter at the perfect tuning time.  
     CONSTITUTION: The oscillation output of local oscillator 3, which supplies the local oscillation frequency to mixture step 4 of signal regeneration system 1 of the receiver, is counted by frequency counter 10 and via gate circuit 9. And the value with which the local oscillation frequency is converted to the reception frequency is preset to counter 10. In case counter 10 presets the intermediate frequency under the detuning state and then counting and displaying the local oscillation frequency, the tuning is carried out so that the specified wave may be received. Thus the instant of the perfect tuning state is detected at detection circuit 13 and then supplied to ratch circuit 11 from control circuit 14 to hold the value of counter 10. And the control is given to gate 9 in order to stop the input supplied to counter 10 after a fixed time. Thus, the display of display unit 12 never changes as long as the receiver is within the tuning band.

Filed: 1982-05-07
Abstract: PURPOSE:To eliminate a protecting time that is set between the transmission and reception bursts, by detecting the reception burst phase only in a section where no burst signal is transmitted and at the start of transmission and then providing a reception period based on the reception burst phase. CONSTITUTION:When a communication starts, a driver 11 is controlled with the output of an AND12 of a control signal 20 which limits the burst length and a control signal 21 which repeats 1 and 0 for each burst period. Then transmission digital signals 24 formed into blocks by a time compressing circuit 1 are thinned and transmitted to a transmission line 6 via a transmission/reception separating circuit 3. At the same time, a receiver 15 is set active only in a nontransmission period of burst by a control signal 26 via a selector 14. Meanwhile, a sychronous signal extracting circuit 17 extracts a burst synchronizing signal 23 and delivers the timing 22 with which the reception phase is applied synchronously with extraction of the signal 23. A transmission controlling circuit 19 uses a signal obtained by giving a synchronous decision 18 to the timing 22 to set a control output signal 10 at 1. Then normal burst transmission control is carried out.
