IPC: H02K15/12
Filed: 1979-02-15
Abstract: PURPOSE: To securely achieve the insulation of a connecting-wire portion with the economy of dripping impregnation being maintained by performing the dripping impregnation with the side having a connecting wire downward, and performing an immersion treatment in the resin by putting the connecting-wire portion into a resin tank.  
     CONSTITUTION: In the case core 1 is inclined and subjected to a dripping treatment, the treatment is performed with the side having a connecting wire 3 downward. At the same time, the portion of the connecting wire 3 is immersed into a resin tank 7 which contains the same resin as the dripping resin by lifting the tank 7. In this method, the resin-impregnation treatment is performed economically, and the reliability for the insulation of the connecting-wire portion can be enhanced. Furthermore, since the resin tank 7 serves to recover the resin which is overflown in the dripping impregnation, the yield rate of the dripping resin can be increased.

Title: Driving method of josephson storage circuit
Inventor: ISHIDA ICHIROU
IPC: G11C11/44
Filed: 1983-02-02
Abstract: PURPOSE:To obtain a simplified driving method of a Josephson NDRO storage circuit which is read nondestructively by connecting the 2nd switch element 9 to the control line of the 1st switch element. CONSTITUTION:Switch elements 8 and 9 are provided with control characteristics shown in figures (a) and (b) respectively. When data is read, a cell current Iy and a read current Ix are flowed through a column line 5 and a row line 7 respectively. In this case, the read current is the same as the current of row line 7 during writing operation. The current flowing to the branches 3 and 4 of a cell A are Imin and IY-Imin=(1-K)IY+Icirc when Icirc flows to the cell A, and KIY and (1-K)IY when not. Consequently, the switch element 9 switches to a voltage state by control characteristics of the cell A in the former case and the element 9 holds a zero-voltage state in the latter case; those two states are discriminated by a detector 14. Then, when IY and IX are set to 0, the cell A is held in a state before the read operation regardless of whether there is Icirc before reading or not, performing nondestructive reading operation.

Abstract: PURPOSE:To avoid an error at recalling, by making the content of a storage circuit ineffective to an exchange if a backup power supply voltage is dropped. CONSTITUTION:When a caller makes on-hook because of the busy state of a called party, the power supply for the storage circuit MEM is changed over to the backup power supply BUP  and the operation of a recalling button is awaited. In this case, if the voltage of the power supply BUP dropps to a lower limit value or less without the operation of a recalling button RDB, a drawing current of a gate G2 is larger than that of a gate G1, and an output B of a flop-flop FF is inverted to ''L''. Since this output is applied so as to close a logical gate circuit LG, the content of the MEM is not outputted to the exchange and becomes ineffective even if the recalling button RDB is operated afterward.
