Title: Charging controller of battery
Inventor: KUMEHASHI TATSUYA
IPC: H01M10/44
Filed: 1990-03-23
Abstract: PURPOSE:To prevent generation of gas due to overcharge and to prevent undercharge by having a voltage detection means for detecting that the terminal voltage of a battery reaches a specified voltage, and a current control means or voltage control means for controlling a charging current or charging voltage for the battery. CONSTITUTION:A battery 1 is supplied with a charging power from a charging power supply 4 through setting of a current control means 5 and reaches a specified voltage V0 at the point of time t1. A voltage detection means 6 detects reaching of the terminal voltage V0 and gives the detection signal to a current detection means 5 and timer 7. The timer 7 gives the measured time T1 to CPU 8 and the CPU 8 operates a charge-ending time T2 and gives it to a timer 9. Also, the current control means 5 changes a phase signal to that for switching a charging current to a small current. From the point of time t1, therefore, the charging power supply 4 lowers the charging current to be supplied to the battery 1 to conduct a supplementary charge and a charge-ending command is given to the charging power supply 4 when a time t2 is measured from the timer 9.

Title: Fuel assembly for boiling water reactor
Inventor: KOGA KATSUMI
IPC: G21C3/328
Filed: 1990-03-23
Abstract: PURPOSE:To improve the dry-out performance by providing a natural uranium fuel charging part within a specific range of fuel effective length downward from the lower end of the 7th spacer of the outermost fuel rod positioned at the control-rod side corner part of the fuel assembly. CONSTITUTION:The natural uranium fuel charging part N is arranged within a 5-10% range of fuel effective length downward from the lower end of the 7th spacer of the control-rod side corner rod. When this charging part N is arranged, the fuel rod output at a part where a dry-out state is easy to occur is decreased, so its limit output ratio (CPR) can be improved by about 15%. Consequently, even if the width of a water gap has maximum deviation from the assumption of a process computer under the influence of a curved channel box, the control-rod side corner rod can be prevented effectively from entering a dry-out state.

The so grasped cloth produces a slack at two cuts of the ring. The slack is removed in a way that tension is applied on cloth by laterally moving a pair of the semicircular rings by means of a motor power and opening and spreading the rings approximately in the shape of an oblong. The grasping device grasping the cloth is raised to the level of the tip of the needle of a sewing machine and approaches a sewing position and stopped in a home position. Sewing is automatically started. Though a sewing machine itself is secured and not moved, simultaneously with sewing starting, the grasping device is moved approximately in the shape of an oblong one round on a horizontal plane along the needle point in linkage with movement of a sewing needle to feed the sewn cloth.
