Title: Detected signal processing circuit of differential pressure sensor
Inventor: SAKAMOTO YUKIO
IPC: G01L13/06
Filed: 1991-08-02
Abstract: PURPOSE:To correctly detect a difference in pressure over a whole pressure range by providing an amplifier for matching direct gradients of output characteristics of two distortion detecting parts and a correcting amplifier for using one of the outputs to generate an error signal. CONSTITUTION:A signal processing circuit comprises pre-amplifiers 10,11 for amplifying outputs y1, y2 of distortion detecting parts 8,9 having amplification factors a1, a2, an amplifier 12 for calculating a difference of respective the outputs yd(=y1-y2) having an amplification factor (g), a correcting amplifier 13 for amplifying the output y2 with amplification factor g' and an amplifier 14 for calculating a difference between outputs gd and g'y2 of the amplifiers 12,13. The amplification factor g' is g(a1/a2-1). In addition offset adjustment is done with an adjusting resistor 14a of the amplifier 14. The difference yd is a signal in proportion to an approximate differential pressure P1-P2 by adjusting the amplification factors a1,a2 to approximately match output characteristic lines of bridge circuits of the detecting parts 8,9. Further more accurate differential pressure signals can be obtained by subtracting an output signal of the amplifier 13 (an error contained in the differential signal yd) from the differential signal d.

Title: Antenna device
Inventor: HATSUDA TAKESHI
IPC: H01Q19/13
Filed: 1988-08-05
Abstract: PURPOSE:To quickly remove snow by sequentially arranging a first layer with low conductivity, a heating unit and a second layer with a small friction coefficient on the surface of the main reflecting mirror of an antenna. CONSTITUTION:A snow-melting member is constituted in such a way that the first layer 13 of a thin film such as a polymeric material having small conductivity and insulation, polycarbonite, for example, is applied on the whole surface of the main reflecting mirror 5, a thin Nichrome wire 14 is arranged zigzag on the layer 13 so as to make it the heating unit 7, and the second layer 15 having the characteristic of the small friction coefficient is applied on the heating unit. When a current flows in the Nichrome wire 14, heat is generated, heat conduction for the main reflecting mirror 5 is prevented by the first layer 13, and snow 16 on the second layer 15 with the small friction coefficient melts. When the contact surface 17 of the second layer 15 and snow 16 melts by heat, and when snow changes into water, it comes to slip easily on the second layer 15 with the small friction coefficient, and snow drops. Thus, the attenuation of a signal due to snow is prevented.

Filed: 1983-10-19
Abstract: PURPOSE:To produce a plasma protein having excellent solubility in water and fluidity, and resistant to the lowering of the activity, by heating virus-contaminated plasma protein in dry state in the presence of the salt of an acidic amino acid and a basic amino acid, thereby inactivating the contaminant virus. CONSTITUTION:Virus-contaminated plasma protein is heat-treated in dry state in the presence of the salt of an acidic amino acid and a basic amino acid (abbreviated as amino acid salt) to effect the inactivation of the virus. The amount of the amino acid salt (e.g. L-lysine.L-glutamic acid salt) is preferably 0.5- 1wt%. The heating is carried out preferably at about 60 deg.C for about 10hr. The amino acid salt exhibits remarkable stabilizing effect to prevent the remarkable loss of the activity of the plasma protein (e.g. albumin, globulin, etc.) which is a valuable blood preparation, and inactivates the possible contaminant virus. Furthermore, the obtained plasma protein has high solubility in water and excellent fluidity, and the present process is useful as an industrial production process.
