Abstract: PURPOSE:To improve characteristic of a silicon oxide film, especially, characteristic in an interface with a silicon film by forming an silicon oxide film covering an island-like crystalline silicon and thereafter annealing it at a specified temperature in atmosphere containing hydrogen nitride. CONSTITUTION:A silicon oxide film is formed on a substrate 101 by sputtering as a base oxide film 102. Then, an amorphous silicon film is formed by a plasma CVD method. Thereafter, a trace of an element which accelerates crystallization is added to the amorphous silicon film, it is thermally annealed and a crystalline silicon film 103 acquired. The crystalline silicon film 103 is etched and an island- like silicon film 104 is formed. A silicon oxide film as a gate insulation film 105 is formed to cover the island-like silicon film 104. Especially in atmosphere of hydrogen nitride such as ammonia and hydrazine, thermal annealing is performed at 600 to 850 deg.C for 0.5 to 6 hours.

Abstract: PROBLEM TO BE SOLVED: To obtain a solid laser oscillator in which an optical resonator is miniaturized by a method wherein the deviation between the set output of a power supply and the output signal of a photodetector is controlled to become zero. SOLUTION: Slight leakage light 3-3 from a reflection film 3-1 which has been executed to the edge of a solid laser medium 3 can be received by a photodetector 5. Since the leakage light 3-3 is in a correlation with a laser beam 3-1 at the ratio of a transmittance, a laser 4-1 which is taken out from an output mirror 4 can be monitored. Consequently, an output signal 5-1 from the photodetector 5 which receives the leakage light 3-3 and the set output signal 8 of an LD power supply 6 are transmitted to an operational amplifier 7, and the LD drive power source 6-1 of the LD power supply 6 is controlled in such a way that the difference between the output signal 5-1 of the photodetector and the set output signal 8 becomes zero. Thereby, the output of the laser 4-1 which is taken out from the output mirror 4 can be stabilized.

Title: Mr imaging instrument
Inventor: ISHIKAWA AKIHIRO
IPC: A61B5/055
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To improve time resolution while space resolution and S/N are prevented from decreasing even though a dynamic imaging based on a GRASE (gradient and spin echo) method is used. SOLUTION: Echo signal groups S1-S9 positioning on the circumference side in the phase encode direction within each group are collected only when subpulse scequence SPS is practiced just before dynamic imaging and the echo signal groups S1-S9 (hatched regions) positioning on the central side in the phase encode direction within each group are collected on each pulse scequence WPS of dynamic imaging. Data in the low frequency region controlling the contrast are collected on each pulse scequence and data in the high frequency region controlling the contour of a reconstituted image are collected only at the time of subpulse scequence and both are commonly used and therefore, the shortest time interval of the pulse scequence can be shortened.

Abstract: PURPOSE:To attain an easy application for a statistic discrimination rule by performing an arithmetic between the spectral data on a color sample and the output of a local color separation system of pictures and estimating the pregeneration probability for each color class at the point of observation. CONSTITUTION:A color picture 300 containing (n) colors is read by an optical system 301 which extracts the local color signals at the point of observation and undergoes the color separation through a color separation filter group 302. Then the picture 300 is converted into electric signals by a photoelectric transducer group 303. The output of the electric signal is amplified by an amplifier circuit group 304 and turned into a color signal vector X which is obtained at the point of observation. An arithmetic circuit 306 operates a discrimination function g(x). While a pre-generation probability arithmetic circuit 309 calculates a pre-generation probability P(Ci) from the color signal data of reference area. A color discriminating circuit 307 discriminates the color of the vector X from the probability P(Ci) and delivers a color code output 308. Thus it is possible to improve the color recognition accuracy for a color pattern including vagueness.

IPC: H01L21/20
Filed: 1984-10-11
Abstract: PURPOSE:When crystalline layers with specific multilayer structures are alternately piled up, the crystal is allowed to grow at a specific low temperature, then growth is effected at a specific temperature to inhibit the mutual diffusion on the heterinterface in the multilayer structure whereby epitaxial crystals of high quality are obtained. CONSTITUTION:When a semiconductive wafer containing crystal layers which have less than 100Angstrom  period and a multilayer structure alternately laminating layers of formula I and II (xnot equal to y; x=0.2-1.0 in Al composition), at first the crystal growth is effected at a temperature lower than 520 deg.C on the base, then heat treatment is carried out at 570-630 deg.C. Superlattice layers are formed with high reproducibility. This process inhibits structural disturbance caused by mutual diffusion on the interface between the layers of formulas I and II. Further, the crystal growth can be conducted at lower temperature to reduce contamination on the crystal growth. Further, restriction in the use of refractory materials can be removed to increase freedom to design the crystal growth devices.
