Title: Method of forming gate insulating film
Inventor: SAKOTA TOMOYUKI
IPC: H01L21/336
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To improve the electric and the boundary characteristics of a very thin film of specific thickness, by heattreating an Si oxide film at specific temperature higher than oxidizing temperature in nitrogen atmosphere after forming the Si oxide film at the specific temperature or less. SOLUTION: After forming an Si oxide film 2 of the thickness of 3nm or less on an Si substrate 1 at 750 deg.C or less, the Si oxide film 2 is heattreated at 850 deg.C that is higher than the oxidizing temperature in the nitrogen atmosphere and then an Al electrode 3 is vacuum-evaporated by vacuum evaporation method. The leak current of an Si oxide film that is oxidized at 650 deg.C and not heattreated is very large, the leak current of the Si oxide film that is heattreated at 850 deg.C is decreased drastically and the larger the maximum allowable voltage, the better. the gate insulating film with lower leak current. The Si oxide film that is heattreated at 850 deg.C after being oxidized at low temperature has higher allowable voltage and smaller interfacial level density.  The Si oxide film is oxidized at 750 deg.C or less for the better controllability of the film thickness as the film thickness is 3nm±2% when it is oxidized at 750 deg.C, the film thickness is 3nm±4% when it is oxidized at 850 deg.C and the controllability of the film thickness is better with oxidized at lower temperature. Therefore, the Sr oxide film is oxidized at the temperature not higher that 750 deg.C for accurately controlling film thickness.

Inventor: HIRAMATSU MASANOBU
IPC: H01F1/09
Filed: 1987-03-26
Abstract: PURPOSE:To obtain a ferromagnetic metal powder without a drop in a remanence ratio by a method wherein, when the ferromagnetic metal powder is to be stabilized by being brought into contact with an oxidizing gas inside a solvent, a process to remove the solvent is executed without exerting a mechanical load on the ferromagnetic metal powder. CONSTITUTION:When a solvent is to be removed, a process to remove the solvent without exerting a mechanical load on a ferromagnetic metal powder is executed by using a single solvent or a mixture of two or more solvents selected from saturated aliphatic and unsaturated aliphatic hydrocarbons, aromatic hydrocarbons such as benzene, toluene, and xylene, alcohols, amines and ketones, none of which reacts with the ferromagnetic metal powder to farm a compound. In addition, a bubble tower, a fluid layer, a stirrer of a container rotary type or a dryer which is not equipped with a mechanical movable part is to be used as a method which does not exert the mechanical load. The obtained ferromagnetic powder can avoid a drop in a remanence ratio substantially.

Title: Large-output germicidal lamp
Inventor: SUGIMOTO TAKAHIRO
IPC: H01J61/72
Filed: 1987-03-26
Abstract: PURPOSE:To prevent the reduction of the relative emission efficiency and the luminous irregularity even if the lamp current is increased and the emission output of the ultraviolet light is increased by setting the diameter of a luminous tube and the lamp current to values satisfying the preset conditions.

Abstract: PROBLEM TO BE SOLVED: To enable the continuous adjustment of the total reduction of area by providing a first stand with anther motor from a motor transmitting roll drive to the other stands, and adjusting the reduction of area independently of the revolving speed of rolls. SOLUTION: Since the motor 8 for driving the rolls in the first stand 18 and a motor 9 for driving the rolls in stands 20, 22 and 24 other than the first stand 18 are different from each other, the revolving speed of the rolls in the first stand 18 and the revolving spead of the rolls in the stands 20, 22 and 24 other than the first stand 18 can be independently controlled. Consequently, the adjustment of the reduction of area in the first stand 18 and that in the second stand 20 can be independently executed. Therefore, the total reduction of area can be continuously adjusted, if necessary. Also, it is widely adiusted without exchanging a gear on a distribution gear device 7 side by multip lying the speed moderation ratio of a transmission means 37 with a roll rotation ratio by the distribution gear device 7.

Title: Fuel injection control device for alcohol-contained fuel internal combustion engine
Inventor: TSUKASAKI YUKIHIRO
IPC: F02D41/00
Filed: 1988-03-26
Abstract: PURPOSE:To prevent worsening of emission of exhaust gas, by a method wherein according to alcohol concentration, an air-fuel ratio feedback control constant is changed in a manner that with the increase in alcohol concentration, a target fuel injection amount is increased. CONSTITUTION:According to an engine load, a fundamental fuel injection amount is corrected by means of an air-fuel ratio correction factor responding to an oxygen sensor output value to decide a target injection amount, and feedback control is made so that an air-fuel ratio is adjusted to a value approximately similar to a theoretical value. In which case, in an internal combustion engine using alcohol-contained fuel, the air-fuel ratio feedback control constant of an air-fuel ratio correction factor is computed so that, with the increase in alcohol concentration detected by a detecting means, a target fuel injection amount is increased. An air-fuel ratio correction factor is determined by the computing result in cooperation with an oxygen sensor output to decide a fuel injection amount. This constitution compensates for the thinning tendency of an air-fuel ratio by an oxygen sensor to detect an O2 amount lower than an actual amount according to alcohol concentration, and enables prevention of worsening of emission of exhaust gas.

Filed: 1978-06-14
Abstract: PURPOSE: To secure formation of a thick heated Si nitride film by oxidizing the heated Si nitride film and then giving it the heat treatment in the atmosphere containing the nitrogen atom.  
     CONSTITUTION: The Si substrate 1 is heat-nitrided to be formed into Si nitride film 2. Then film 2 is oxidized to secure Si oxide film 3 on the surface. The heat treatment is then given to film 3 in the atmosphere containing N atom. As a result, the  N atoms diffuse into film 3 and furthermore transmits through film 2 to reach the  surface of substrate 1. And with the reaction on the surface, film 2 increase its  thickness. In these processes, film 3 is gradually converted into the Si nitride film  with the thickness being reduced. And thus, the layer composed of the Si nitride  film is regenerated substantially, obtaining heated Si nitride film 5 featuring a fine  structure.
