IPC: H01L29/812
Filed: 1988-09-30
Abstract: PURPOSE:To keep a source-to-drain saturated current of a GaAs MESFET within a prescribed permissible range and to enhance radiation resistance by specifying a carrier concentration in an active layer before irradiation with radiant rays. CONSTITUTION:A reduced amount of a carrier concentration NID', N2D in an active layer by irradiation with radiant rays of a total radiation amount of R is designated as DELTAND; carrier mobilities in the active layer before and after irradiation with the radiant rays are designated as mu and muA, respectively. In this case, a carrier concentration N2D in a lower-side layer of the active layer before irradiation with the radiant rays is set at N2D>DELTAND/{1-[alphaLL(mu/muA)]<1/2>}. As a result, even when the total radiation dose of R of the irradiated radiant rays is not only 1X10<9> roentgens or below but also higher than this value, a source-to-drain saturated current Idss of a GaAs MESFET can be kept within a prescribed range (a permissible range decided by a signal processing circuit) at a preset radiation dose. Accordingly, a semiconductor device constituted so as to be provided with the GaAs MESFET and with the signal processing circuit functioning together with the FET can be operated normally according to an initial design value. Thereby, it is possible to enhance radiation resistance.

Title: Coriolli mass flowmeter for magnetic liquid and magnetic liquid feed equipment using the same
Inventor: FUJIKATA SHINGO
IPC: G01F1/84
Filed: 1992-09-17
Abstract: PURPOSE:To measure the flow rate of a magnetic liquid with high accuracy by setting the center line average roughness of the inner wall of a U-shape conduit to a predetermined value or less. CONSTITUTION:A U-shape conduit 2 is fixed to a support member 3 in the vicinity of the open ends thereof and the reciprocally moving member 4 held by a holding plate 5 is connected to the conuit 2. The conduit 2 generates constant amplitude in natural fequency at the part of the member 3 by the member 4 in such a manner that a tuning fork is vibrated. A magnetic liquid enters the conduit 2 from an inlet 7 to pass through the vibrated conduit 2 and flows out of an outlet 8 while generates distortion in the conduit 2. A pair of the detection means 6a, 6b fixed to a support wall 9 measure the quantity of distortion of the conduit 2 proportional to the flow rate of the magnetic fluid to convert the measured value to voltage. The center line average roughness of the inner wall of the conduit 2 is set to 1.0mum or less (cut-off value: 0.25mm), pref., 0.7mum or less. It is not pref. that the center line average roughness exceeds 1.0mum because the magnetic liquid begins to adhere to the fine unevenness of the surface of the inner wall of the conduit 2 and the mass of the conduit 2 changes. The surface roughening processing of the inner wall of the conduit 2 is executed, for example, by electrolytic polishing.

Title: Method for distinguishing border of detected values by multi-point sensor
Inventor: IKEDA AKIO
IPC: G01N21/47
Filed: 1990-09-18
Abstract: PURPOSE:To reduce influence by abnormal measurement values and enable correct determination by adding respectively predetermined weights to output measurement values of a plural of adjacent detectors and then comparing the averaged values with one another. CONSTITUTION:Outputs of sensors S1 to Sn are respectively input 1 and weighted 2, and output measurement values of the sensors are processed and output by average value calculation 3 and comparison 4. Weighting is done where an output of the sensor S1 is a1, an output of the sensor S2 is a2, an output of the sensor S3 is a3 and so on until an output of the sensor Sx is ax, wherein a value to be averaged in a subsequent step is weighted in advance so that a1 is multiplied by 1, a2 is multiplied by 2, and a3 is multiplied by 1. When a result averaged in a step 3 is assumed to be b2, b2=(a1+2a2+a3)/4. Therefore influence of a1 affecting the output of the subsequent step is 1/4, influence of a2 is 1/2 and influence of a3 is 1/4, so that even if there is an irregular value among a1, a2, a3 to cause erroneous determination, the influence to b2 is 1/4 or 1/2.
