Title: Semiconductor storage
Inventor: HORIKAWA JUN
IPC: G11C7/10
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To allow a semiconductor storage for repeating read and write operation in a specific cycle to quickly and stably operate. SOLUTION: A read/write pulse width control circuit 2 shortens and lengthens the pulse width of a read/write pulse width control signal 12RW on read and write operation, respectively. A column decoder 3 outputs a column selection signal Y with the same pulse width as that of the signal 12RW, and a column selection gate 4 connects a pair of bit lines BL and XBL to a pair of data lines DL and XDL while the column selection signal Y is set to a high level. On the read operation, the equalizing period of a pair of the data lines DL and XDL is secured to be sufficiently long, and at the same time the connection period between a pair of the data lines DL and XDL and a pair of the bit lines BL and XLB is secured to be sufficiently long, thus quickly and stably performing read/write operation.

When the temperature of  cooling water has exceeded 70 deg.C, the control circuit 38 reads out a table value gammamax  stored in a read-only memory 56, on the basis of the output of the cooling water temperature sensor 16. When the effective synchronous injection time gammal is longer than the  table value gammamax, the table value is used as the effective synchronous injection time.  When the effective synchronous injection time gammal is longer than the upper limit gammau of  the table value gammamax, the upper limit is used as the effective synchronous injection time.  An ineffective injection time gammav determined at the time of the fall in the battery voltage is added to the effective synchronous injection time gammal to determine a synchronous  injection time gammas to control injection valves 36.

Abstract: PURPOSE: To maintain sealing performance of a gas nut, and reduce an occurrence rate of liquid leakage failure by intermittently performing welding from a part whose temperature is low when a battery case and a fitting part of a cover plate are welded and sealed by a laser welder. CONSTITUTION: A laser beam emitter of a pulse type YAG laser welder is moved, and pulse oscillation of the laser beam emitter is started from a point A on a rectangular fitting part 4 of a battery case 1 and a metallic cover plate 2. The laser beam emitter is moved, for example, at speed of 8.0mm/sec up to a point B on the side along a fitting part 4ab, and a joining part 4ab is welded. When it reaches the point B, the pulse oscillation is temporarily stopped, and this emitter is moved to a point C. Next, the pulse oscillation is resumed at the point C, and the emitter is moved up to a point D along a fitting part 4cd. The pulse oscillation is also resumed at the point A, and welding is performed, for example, at speed of 12.0mm/sec up to the point D through two corner parts in the clockwise direction along a fitting part 4ac.  In this way, since the welding is intermittently performed from a part whose temperature is low, an occurrence rate of liquid leakage failure is reduced.
