Title: Voltage detection circuit
Inventor: UENISHI AKIO
IPC: G01R19/165
Filed: 1990-08-17
Abstract: PURPOSE:To widen a voltage detection range and to enhance high frequency characteristics by measuring the voltage generated from a normally-ON type electrostatic induction transistor whose gate is earthed under a predetermined bias current. CONSTITUTION:When a normally-ON type electrostatic induction transistor Tr2 is combined with a current source 3, no current flows to the gate of the Tr 2 and, therefore, the current value of the current source 3 becomes a drain current and the source voltage of the Tr 2 is determined by self-bias so as to obtain the breakdown voltage corresponding to the voltage Vc applied across the drain and source of the Tr 2. Then, output voltage Vo is obtained in the ratio of the breakdown voltage across the drain and the source to the bias voltage applied across the gate and source, that is, the voltage dividing ratio of the reciprocal of a voltage amplification factor. Therefore, a voltage detection range is made extremely wide from zero to the withstand rated voltage of the Tr 2 and output voltage is issued in a ratio of 1/voltage amplification factor with respect to detected voltage and, further, output voltage is easily built in a monolithic power IC in an IC level and high speed response can be always achieved.

Title: Method for estimating superconductive thin film and manufacture of superconductive device
Inventor: NAKAMURA TOMOJI
IPC: G01N21/55
Filed: 1990-08-22
Abstract: PURPOSE:To estimate a size and distribution of grains wherein a-axis directions are orthogonal to each other by observing a reflected light image of a polarization component which is slightly different from a direction orthogonal to a polarization direction of applied light to a polycrystal superconductive thin film. CONSTITUTION:Polarized light is applied from a light source 11 via a polarizer 12 to a surface of a polycrystal superconductive thin film formed on a monocrystal substrate 4, and a reflected light image on the thin film is observed via a light detecting element 15 having a polarization surface 90 deg. different from the applied polarized light and a CCD camera 17. When the substrate 4 is rotated in its plane and fixed at a position where the reflected light image is the brightest, an a-axis or b-axis orientation of a grain of the thin film has an angle of 45 deg. with respect to the polarization surface of the polarized light applied together, so that brightness of grains whose a-axis directions are orthogonal to each other is equal. If the polarization surface of the detecting element 15 is slightly rotated, difference in brightness occurs between grains whose a-axis directions are orthogonal to each other. It is possible to distinguish grains by the difference in brightness, so that the grain sizes and distributions on a plane can be simply measured.

Abstract: PURPOSE:To transmit information preferentially and urgently by allowing a data transmission equipment which is connected to a ring-shaped circuit to transmit a transmission right frame to itself after transmitting an information frame, and inhibiting the transmission of other station. CONSTITUTION:Plural data transmission equipment 1 which each has an external device 3 are connected to the looped transmission circuit 2. One transmission equipment 1 when the transmission right frame addressed to an unspecified station or its station is transmitted rough the transmission circuit 2 inputs this transmission right frame to obtain the right of transmission addressed to its station.
