IPC: G01L7/08
Filed: 1990-01-17
Abstract: PURPOSE:To prevent an output based upon unnecessary disturbance from being generated by providing a step part at the peripheral edge of the diaphragm holding part of a support base and forming the holding part as a projection part which is isolated from the circumference. CONSTITUTION:The diaphragm holding part 23 which holds a diaphragm 22 is formed almost at the center part of the support base 21 and pressure is applied to the diaphragm 22 from a pressure intake 15 provided on the support base 21. This diaphragm type pressure sensor 20 has the step part 24 formed at the peripheral edge of the diaphragm holding part 23 of the support base 21 and the diaphragm holding part 23 is formed as the projection part which is isolated from the circumference. Consequently, even if unnecessary stress due to twisting at the time of protection case pressing-in operation or if other pressure sensors 20 are stressed variously, the stress is prevented from being transmitted to the diaphragm 22 to reduce the disturbance due to the strain output of the pressure sensor 20.

Inventor: TAKAHASHI TOORU
IPC: H03G3/12
Filed: 1979-01-25
Abstract: PURPOSE:To enable to perform broad band amplification having the gain selection functions less in the points of adjustment and in drift, by comparing the input signal with the difference signal voltage between the output terminals by means of the first operational amplifier and performing negative feedback the difference to the amplifying transistor. CONSTITUTION:The operational amplifiers 61, 68 and 80 are placed between the signal input terminal 1 and signal output terminals 2, 3. Further, the amplifier 68 inputs the output of the output terminals 2 and 3, amplifies the potential difference between the output terminals 2 and 3 and feeds it to the operational amplifier 80. This amplifier 80 compares the input signal with the difference signal voltage between the output terminals 2 and 3, and the difference is negative-fed-back to the base of the amplifying transistor Tr28. This negative feedback compensates the variation in the potential difference between the terminals 2 and 3 accompanied with the gain selection and with the drift due to the amplifying circuit consisting of Tr27...34. Thus, the broad band amplification having the gain selective functions less in the points of adjustment and in the drift can be made.

IPC: G01R23/06
Filed: 1989-01-13
Abstract: PURPOSE:To detect the frequency at a high speed without finding an impossible solution of an arithmetic output by bringing five pieces of amplitude value of an AC electricity quantity of an electric power system to sampling in a prescribed period, and executing a prescribed operation after the A/D conversion. CONSTITUTION:Five pieces of voltage values are brought to sampling in a sampling period T, and thereafter, brought to A/D conversion. Subsequently, a third sample value is squared by a square device 7, a first and a fifth sample values are multiplied by a multiplier 6, and by a subtracter 9, {V(2T)<2>-V(0).V(4 T)} is derived. Also, by a subtracter 10, a multiplied value of a second and a fourth sample values derived by a subtracter 8 is subtracted from an output of the square device 7, and {V(2T)<2>-V(T).V(3T)} is derived. Next, by a divider 11, an output of the subtracter 9 is divided by an output of the subtracter 10, and an output Y=4cos<2>T is derived. From this output Y, a frequency (f) is derived by an inverse trigonometric function arithmetic means. In this case, since it does not occur that a denominator of the output Y becomes '0', the frequency is detected at a high speed and with satisfactory reliability.
