Patent JP-H03155652-A (JP)
Title: Semiconductor memory device and manufacture thereof
Inventor: IWASE TAIRA
IPC: H01L27/10
Filed: 1990-04-05
Abstract: PURPOSE:To prevent the generation of erroneous operation such as the fusion- cutting of a fuse, which need not be fusion-out, by setting the threshold voltage of a second transistor for fusion-cutting the fuse in the other spare memory cell when the fuse of one spare memory cell is fusion-cut. CONSTITUTION:Only a fuse F1 is fusion-cut, and a fuse F2 need not be fusion- cut. A word line L1 in wring word lines is set at a high level, and a word line L2 is set at a low level. Consequently, a transistor T1 is brought to a conductive state, a transistor T2 is brought to a non-conductive state, and program currents I are made to flow only through the fuse F1. Noises are generated between another writing word line L2 and a ground wiring G1 at that time, the potential V1 of the writing word line L2 and the potential V2 of the ground wiring G1 are fluctuated, and the potential difference VGS of both potential is increased. The threshold voltage Vth of the transistor T2 is set at a value larger than potential difference VGS. Accordingly, the non- conductive state is maintained in the transistor T2, and program currents I are not made to flow through the fuse F2, thus preventing the fusion-cutting of the fuse F2.

IPC: G01G13/12
Filed: 1988-04-15
Abstract: PURPOSE:To enable the dropping charge of an aimed weight reliability into a weighing hopper, by stopping the dropping charge of a powder substance from a charging port at the time point when a load cell measures the weight of the powder substance obtained by subtracting a head weight from the aimed weight. CONSTITUTION:The weight of a powder substance in a weighting hopper 12 in the course of the dropping charge thereof is measured a plurality of times at each unit time and also measured values at each unit time are averaged, whereby a flow rate X of the powder substance charged by dropping is detected. Besides, a head weight Y in the air is determined from the product tX of the amount X charged by dropping and a drop time (t) of the powder substance. At the time point when a load cell 13 of the weighing hopper 12 measures a difference W-Y between an aimed weight W and the head weight Y as the weight of the powder substance, the dropping charge of the powder substance from charging ports 6, 7 and 8 are stopped. Thereby a timing of blocking of the charging ports 6, 7 and 8 can be detected automatically while the powder substance is charged by dropping, and the powder substance can be charged by dropping into the weighing hopper 12 and weighed therein as much as the aimed weight reliably even when the kind of the powder substance and the flow rate of the substance charged by dropping are varied.

The sensor 1 moves to the right on the rail 5 while measuring the height to the object to be measured at a constant speed and at constant interval, and when the sensor is brought into contact with the switch 6 on the right, the measurement of the height is finished. At the same time, the minimum measured value which corresponds to the trolley height among the measured values written in the storage device by the computing circuit of the processor 2 is detected, and the deviation of the trolley line is calculated from the position of the minimum value occupied among the total measured values and the distance of movement of the sensor. The height and deviation of the troley line is numerically indicated or outputted in print by the indicating circuit of the processor 2.
