Title: Active vibration isolating method
Inventor: UCHIDA KIMIO
IPC: G05B13/00
Filed: 1990-02-09
Abstract: PURPOSE:To suppress vibrations on low frequencies with a small amount of energy, by making a control power stopped or variable until the displacement and the velocity of the table reach specified levels from the rest position. CONSTITUTION:A table 13 to be vibration removed is provided on a floor 10 through an air spring 11 and dash-pot 12, and an electromagnetic actuator 14 is arranged to apply an outer control power (u) to the table 13. Displacements x1 and velocities x2 of the table to be vibration removed are measured to obtain a two dimensional phase plane P expressed with the displacement x1 and the velocity x2. If a function sigma=s1x1+x2 (where s1 is an inclination between the displacement x1 and the velocity x2) is defined on the phase plane P, the plane P is divided by the straight line sigma=0 into two regions P1 and P2 corresponding to sigma>0 and sigma<0 respectively. The control power (u) is operated so that motions of a displacement x1 and a velocity x2 in their respective regions are oriented toward the straight line sigma=0, and slid on the straight line sigma=0, in other words, a sliding mode is generated to converge the motions on the rest position O, whereon both of the displacement x1 and the velocity x2 are zero.

Title: Manufacture of semiconductor device
Inventor: SHITSUPOU OSAMU
IPC: H01L27/10
Filed: 1987-02-12
Abstract: PURPOSE:To increase breakdown strength of the trench type capacitor of a dynamic RAM, by forming, on a single crystal silicon wafer, a trench wherein the face orientation of the bottom surface and the side surface of the trench is (100) and that of a part where surfaces are in contact is not (100), and forming, after that, a thermal oxidation film. CONSTITUTION:A P-type Si substrate 2 is subjected to etching applying an SiO2 film 12 to a mask, and a trench is formed. In this process, the etching is so performed that a part where the surfaces of the trench are in contact becomes a face other than (100). This can be easily done by an isotropic etching (RIE). Then As is diffused into the bottom surface and the side surface of the trench, and an N<+> layer 3 is formed. After the film 12 is eliminated, an SiO film 1 is formed by a thermal oxidation under the condition where the rate of oxidation depends largely on the face orientation. A polysilicon film 6 in which phosphorus is doped is formed on the SiO film 1. Thereby, the oxide film of a part where surfaces are in contact is made thicker than the bottom surface and the side surface, and so breakdown strength is improved.

Title: Production of superconducting oxide thin film
Inventor: YOSHIMATSU MASAHIRO
IPC: H01L39/24
Filed: 1988-02-13
Abstract: PURPOSE:To obtain a superconducting oxide thin film at a low calcination temperature, by applying a solution of an oxyalkoxide complex of Y, Ba and Cu to a substrate, thermally decomposing the complex and calcining in an oxidizing atmosphere. CONSTITUTION:The objective thin film can be produced by applying a solution of an oxyalkoxide complex of Y, Ba and Cu to a substrate, thermally decomposing the complex and calcining in an oxidizing atmosphere. The oxyalkoxide complex can be thermally decomposed e.g., at about 500-700 deg.C and calcined at a relatively low temperature (e.g., about 800-900 deg.C) in an oxidizing atmosphere to form a superconducting oxide. Accordingly, a superconducting oxide thin film can be formed by applying a solution (organometallic solution) of an oxyalkoxide complex adjusted to a proper viscosity to a substrate and subjecting the complex to thermal decomposition and calcination. Since the formation of oxide by the thermal decomposition of an organometallic solution is carried out by deesterifying reaction, the elements can be mixed in molecular level and the calcination temperature can be lowered.
