Title: Manufacture of angular velocity sensor
Inventor: KIMURA RYO
IPC: G01C19/56
Filed: 1986-04-23
Abstract: PURPOSE:To adjust sensitivity, by a method wherein acceleration is preliminarily acted by applying vibration to a sensor element in the deflecting direction of a piezoelectric vibrator for detection and the free end of a high sensitivity element is cut using laser. CONSTITUTION:A detection signal is taken out as the output of flexural oscillation of piezoelectric bimorph elements 1 for detection when the joints 4 of said elements 1 are set as support points. At this time, because Coriolis forces are different by 180 deg. in a drive vector direction, said piezoelectric bimorph elements 1 are deflected to reverse directions. Therefore, the piezoelectric bimorph elements 1 for detection are connected so that the signals thereof are taken out as a sum signal. A sensor is preliminarily vibrated to an input acceleration direction by a vibrator and, in order to set acceleration output due to sensitivity difference to zero by tuning, the electrodes 5 at the free ends of the piezoelectric bimorph elements for detection are cut or removed by laser until output comes to zero with respect to input acceleration to regulate the sensitivity difference between left and right. By this method, the sensitivity to acceleration due to usual assembling can be improved by 30-40dB.

Title: Semiconductor storage device
Inventor: YAMAMOTO AKIRA
IPC: G11C7/06
Filed: 1981-06-19
Abstract: PURPOSE:To reduce the power comsumption of a sense amplifier, by turning off an FET for constant current source by a prescribed control signal during the nonselection of a chip or in the writing mode. CONSTITUTION:In the chip nonselection mode when an external terminal -CS is set at a high level, the control signal R is set at a low level and an MISFETQ32 functioning as a constant currrnt source is turned off. In the chip selection mode when the terminal -CS is set at a low level, the signal R is set at a low level with the Q32 turned off as a long as an external terminal -WE is in the writing mode of a low level. Accordingly the signal R is set at a high level with a sense amplifier SA set in the amplifying mode only in the reading mode when the terminals -CS and -WE are set at a low level and a high level respectively.
