Abstract: PURPOSE:To obtain a gate oxide film homogeneous in thickness and crystal and to improve electric characteristics of a device by removing a spontaneous oxide film grown on the surface of a substrate with hydrogen gas, and then oxidizing it. CONSTITUTION:A silicon substrate 1 is placed on a stage 2 in a reaction vessel 3. The vessel 3 is evacuated in high vacuum by a vacuum system 4. Hydrogen gas of suitable amount is supplied from a gas supply system 5, and then a microwave 8 is supplied through a waveguide 7 while applying a magnetic field by a magnet coil 6. In this case, hydrogen gas 9 becoming an ion plasma by an electron cyclotron resonance effect is reacted in a reducing manner with a spontaneous oxide film 10 on the substrate 1, and an SiOx film is, for example, decomposed to be removed like H2O+SiH4. Thereafter, when it is crossed across the magnetic field of the coil 6 and the microwave 8, the hydrogen gas is adsorbed to the cleaned substrate 1 to be stabilized.

Title: Automatic correcting apparatus of two-dimensional slant error in surveying instrument
Inventor: WADA KAZUAKI
IPC: G01C5/02
Filed: 1988-11-25
Abstract: PURPOSE:To make it possible to collimate and set the direction of a true zenith in an automatic vertical collimator directly, by suspending a single pendulum from horizontal pivots in an instrument so that the pendulum is freely moved, and suspending a suspending-ribbon crossing type pendulum beneath the single pendulum. CONSTITUTION:A single pendulum 3 is suspended from horizontal pivots 1 through bearings 2 in a surveying instrument so that the pendulum is freely moved. A suspending-ribbon crossing type pendulum 4 is suspended with four thin metal ribbons 4a beneath the single pendulum. When the single pendulum 3 is inclined at an angle theta in the direction perpendicular to the moving direction of the single pendulum, a pendulum part 4b is inclined by theta/2 in the opposite direction. When the instrument is inclines by theta and beta in the back and forth directions and the right and left directions and vertical luminous flux 8 is inputted to a reflecting member 7, reflected luminous flux 5 is outputted at an inclined angle of two times the inclination theta/2 of the member 7, i.e., theta, from the zero-inclined state of the pendulum 4. Thus the inclination of the instrument is corrected. Meanwhile, since the pendulums 3 and 4 are inclined with respect to the instrument and directed to the vertical direction, the inclination of the instrument in the right and left directions is corrected. Therefore, even if the instrument is inclined in any direction in the two-dimensional directions, the vertical light axis 8 can be always maintained in the vertical direction.

Title: Overvoltage protective circuit
Inventor: UEDA KAZUNORI
IPC: H02H3/20
Filed: 1990-11-02
Abstract: PURPOSE:To restore a device without sending any person to the site of the device by disconnecting a main circuit and, at the same time, evaluating an input voltage when an overvoltage is inputted and, when the input voltage drops within a prescribed period of time, automatically restoring the device. CONSTITUTION:When the voltage 101 inputted from a power source 1 exceeds a preset fixed level at the input terminal of an overvoltage protective circuit 2, the circuit 2 discontinues the output to a main circuit 3 by turning off the switch of its own circuit and, at the same time, sends a discontinuing signal 102 to an overvoltage evaluation circuit 4. The circuit 4 starts its own timer set to fixed time by using the signal 102 as a reference and evaluates the input voltage 101 during the set period. When the voltage 101 drops during the set period, the circuit 4 sends a restoring signal 103. Upon receiving the signal 103, the overvoltage protective circuit 2 again turns on the switch and supplies electric power to the main circuit 3. As a result, the main device is automatically restored.

Title: Method for measuring superoxide anion radical derived from blood or constituent component thereof
Inventor: NAKAMURA KUNIE
IPC: G01N21/76
Filed: 1990-11-01
Abstract: PURPOSE:To make it possible to measure superoxide anion radical directly and sensitively by using blood and its constituent component as an object to be measured and Cypridina luciferin or its derivative as luminescence reagent. CONSTITUTION:At first, blood or its constituent component as an object to be measured is fractionated. The constituent component of a cell such as erythrocyte is used by breaking the cell. The cell breaking is performed by inputting the fraction cell into hypotonic solution represented by, e.g. water, Tris buffer or the like. Thereafter, Cyprina luciferin or its derivative is used as luminescence reagent for the solution obtained by the cell breakdown. The amount of the superoxide anion radial is measured by chemiluminescence. It is preferable that the cell breaking operation is made to progress at the same time of the addition of the luminescence reagent. The luminescence reagent is the derivative of the Cypridina luciferin, and it is preferable to use 2-methyl-6-phenyl-3 or the like. Thus, the superoxide anion radical can be directly measured sensitively.
