Title: Flash memory device and its screening method
Inventor: KATSUMATA MASABUMI
IPC: H01L29/792
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To screen respectively and optimally a peripheral circuit and a memory area by applying a voltage to a memory element through a high voltage generation circuit and providing a switch circuit between the memory area and the peripheral circuit such as the high voltage generation circuit, etc., of an electrically rewritable device. SOLUTION: When the screening is performed, the switch 50 terminal T1 is connected to a terminal T3, and the high voltage generation circuit 30 is separated from a memory cell area 10, and a prescribed voltage is applied from an external input terminal to respective memory cells, and the memory cell area 10 is screened. Further, a prescribed load is applied to the peripheral circuit in the state separating the high voltage generation circuit 30 from the memory cell area 10 to screen the peripheral circuit. Thus, the screening is performed optimally. Then, since a device is shipped after the device is lowered to a prescribed instantaneous failure rate in an accidental failure interval also in either one between the memory cell area 10 and the peripheral circuit, a flash memory device with extremely high reliability becomes possible.

Title: Fixing device
Inventor: UMEZAWA KAZUMI
IPC: G03G15/20
Filed: 1984-05-09
Abstract: PURPOSE:To enable satisfactory fixing with adequate pressurizing force even if an ambient temp. is low by setting the thermal transformation point of a pressurizing spring made of a shape memory alloy in such a way that the pressurizing force below the thermal transformation point is larger than the pressurizing force above the thermal transformation point. CONSTITUTION:A pressurizing roller 5 is pressfurized by the deformation of a pressurizing spring 9 made of the shape memory alloy. The shape memory alloy has such thermal transformation that the spring 9 contracts to a length L at the thermal transformation point or below. The L is set longer by an actual use length L, at which the pressurizing force P is obtd. The length of the spring 9 is so set as to extend to L'' at which (L'<L<L'') is obtd. The pressurizing force of the roller is consequently increased from ordinary pressurizing forde when the temp. is low and therefore the adequate pressurizing force is obtd. and always satisfactory fixing is executed even if the environmental temp. falls.

Filed: 1986-04-24
Abstract: PURPOSE:To shorten the investigation time of an inter-connection relation, by a method wherein an inter-connection relation is successively investigated from a terminal point showing a large capacity value and investigation is conducted only on an inter-connection relation, wherein the length between terminal points is a predetermined value or less, when the max. points shows a predetermined value. CONSTITUTION:Terminal points 4 consisting of P1-P24 are provided to a pair board 1 and the capacity value of each terminal point 4 is measured by a capacity measuring device 13. Next, an inter-connection relation between the terminal point 4 showing the max. capacity value and that showing a capacity value approximate to said max. one is investigated by a resistance measuring device 12. This investigation is repeated until the max. capacity value of the terminal point among non-investigated terminal points comes to a predetermined capacity value. After the max. capacity value reaches the predetermined capacity value or less, the investigation is conducted only on the inter-connection relation wherein the length between the terminal points is a predetermined one or less and the measurement by the apparatus 12 is not performed with respect to the inter-connection relation wherein the mutual position of the terminal points exceeds the predetermined length. By this method, the investigation time of connection relation can be shortened.
