Title: Gain control device
Inventor: DOI MASAYUKI
IPC: G01S7/34
Filed: 1989-06-29
Abstract: PURPOSE:To reduce switching noise without answering a slight variation in an input signal by providing the gain control device with an A/D converter for forming a digital signal and a subtractor for subtracting the digital signal from a threshold level. CONSTITUTION:An output signal from a differential amplifier 40 is supplied from an A/D converter 42 and converted into an output signal S15. The subtractor 43 outputs a difference between the output signal S15 from the A/D converter 42 and a threshold level signal 16 as an output signal S17. Then, the output signal S17(Z) of the subtractor 43 is latched by a latch circuit 44 and an output signal S18 is outputted. The output signal S20(W) of a ROM 46 is outputted from the output signal S18 and the output signal of a latch circuit 44. An output signal S25 from a driving circuit 50 is always set up to a fixed value, so that the signal processing operation of a variable attenuator 52 is fixed and switching noise is not generated.

Title: Differential type magnetoresistance effect element
Inventor: OKABE HIROTAKA
IPC: G01R33/06
Filed: 1988-07-05
Abstract: PURPOSE:To enable the attainment of an output change twice as large as the one of a single element and a resolution twice as large as the one of it by connecting two differential type magnetoresistance effect elements (MR elements) to a bridge circuit so that each of them forms one side of the bridge, and by impressing a bias magnetic field thereon discretely. CONSTITUTION:MR elements 1a and 1b are patterned so that the easy-magnetization axis is set in the longitudinal direction of a stripe, and a sense current 5 is supplied in the longitudinal direction of the stripe, while a bias magnetic field 3 is impressed in the width direction. Then the magnetizations 2 of the elements 1a and 1b are rotated by 45 deg. respectively and made parallel to each other. When a minute external magnetic field 4 of about 10e or below is impressed in this state, both of the magnetizations 2 of the elements 1a and 1b are rotated in the same direction 2b. In the element 1a, the element resistance becomes large since the rotation is made in the longitudinal direction of the element, while the element resistance becomes small in the element 1b, since the rotation is made in the direction of the short axis thereof. When the elements 1a and 1b are connected to two sides of a bridge respectively, according to this constitution, voltages due to the resistivity of the elements are canceled, and the sum of only the changes in voltages of the two MR elements due to the external magnetic field 4 can be obtained.

IPC: C22B21/06
Filed: 1980-11-28
Abstract: Apparatus and process for automating a vacuum degasification cycle for metal alloys, particularly aluminum alloys. The process comprises adjusting the degasification speed to sequentially correspond to a plurality of sets of degasification speed parameters. Each set of degasification speed parameters corresponds to a predetermined desired degasification speed. The degasification speed may be adjusted by adjusting the vacuum surrounding the alloy. The degasification speed is triggered to change from corresponding to one set of parameters to another set of parameters by the sensing of a series of predetermined partial pressures of gas in the alloy. The apparatus includes an inlet-outlet assembly for transforming given indications into a numerical form for the parameters of the degasification cycle and a calculator assembly adapted to transform the speed of degasification into variations of theoretical partial pressure and to regulate the pressure in the enclosure of the furnace to obtain an identical variation to that required based upon the indications of the standard curve placed in the assembly memories. Several furnaces may be regulated. The temperature of the metal may be regulated at a level equivalent to that required before casting. The apparatus can include a microprocessor.
