Title: Measuring method of semiconductor memory
Inventor: WATANABE YOSHIO
IPC: G11C29/50
Filed: 1982-02-27
Abstract: PURPOSE:To take a measurement of the threshold value of a complete LSI which is conventionally impossible by analysing the operation of a flip-flop from the inversion of a storage state caused by a temporary drop in power voltage. CONSTITUTION:A voltage VCC is lowered approximately to the threshold voltage of a driving transistor (TR) in a memory cell at xV/sec (procedure 1) and then raised to its original level again (procedure 2). Then, the stored information in the memory cell 1 is read out to check whether inversion to ''1'' is caused or  not (procedure 3). The minimum value of the lowered voltage VCC is set to  lower values gradually at ZmV steps and the procedures 1-3 are followed repeatedly. In the procedure 3, when the stored information is inverted to ''1'', the  minimum value of the lowered VCC in the preceded procedure 1 is regarded as  the critical voltage of the TR which was conducted just before the power voltage is lowered between two driving TRs in the memory cell. On the basis of  this critical voltage, the threshold voltage of the TR is found.

Title: Liquid-sealed rubber mount
Inventor: HIRAKI HIKOSABURO
IPC: F16F13/08
Filed: 1994-02-04
Abstract: PURPOSE:To maintain a vibrationproof liquid-sealed rubber mount in such state as ensuring high vibration isolation characteristics in medium and high frequency bands, freedom from the induction of a resonance with a shock vibration over a wide frequency band, and less rolling. CONSTITUTION:A liquid sealing chamber 20 is fixed to one end of a mount case 11, end a damper plate 22 is housed therein. A guide shaft 14 having a bolt 27 is fastened to the damper plate 22 with a nut 24, and the guide shaft 14 and the case 11 are jointed to each other with a cushion rubber 28 having cylindrical lamination plates 29 clamped inside. The cushion rubber 28 has hardness Hs between 45 and 60 degrees for keeping a small spring constant. Also, high attenuation liquid having viscosity between 50,000 cst and 150,000 cst is sealed in the chamber 20. According to this construction, a spring constant for a vertical vibration becomes small, thereby providing high vibrationproof characteristics in a high frequency band. Also, no resonance is induced with a shock vibration, due to the existence of the high attenuation liquid. In addition, the cushion rubber 28 has a cylindrical and laminated form. Thus, a spring constant in a horizontal direction becomes large, thereby enabling rolling to be reduced.
