Title: Method for controlling content of ferrous oxide in decarburized oxide layer of grin-oriented silicon steel
Inventor: KONDO YASUMITSU
IPC: C21D1/26
Filed: 1992-07-10
Abstract: PURPOSE:To obtain the desired amount of FeO even when the temperature, the dew point, the plate thickness and the surface condition are fluctuated, by detecting the dew point of the atmospheric gas, the furnace temperature or the plate temperature, and controlling the dew point or the like so that the amount of FeO in the decarburized oxide layer during the decarburized annealing which is estimated by the formula may be the target value. CONSTITUTION:When grain-oriented silicon steel which is carried into a furnace between the heating zone 2 and the soaking zone 3 of a decarburizing annealing furnace 1 is heated, soaked and decarburized, the oxide layer containing SiO2 is formed on the surface of the steel plate, and a part thereof is reduced in the reducing zone 4. The water content of the atmospheric gas in the heating/soaking zone which flows in the reverse direction to the plate passing direction and is discharged out of the furnace is consumed in the decarburizing reaction, and the distribution of the dew point is realized according to the reaction in the furnace. The plate temperature and the dew point of the in-furnace atmospheric gas are respectively detected radiation thermometer 13, and a dew-point instrument 14, and an arithmetic unit 15 estimates the amount of FeO by the specified formula based on these detected values and the plate-passing speed of the steel plate 5, the plate thickness, and the C quantity before the decarburizing annealing. One or more parameters among the dew point of the atmospheric gas, the heating temperature, the reducing temperature and the plate-passing speed are controlled so that the difference between the estimated amount of FeO and the target value may be zero.

Title: Optical modulating and scanning device and optical head utilizing the same device
Inventor: ONUKI HIDEO
IPC: G11B7/125
Filed: 1988-07-26
Abstract: PURPOSE:To eliminate the fluctuation in wavelength and to alow completely separate modulation and scanning by forming an optical modulator which modulates laser light according to propagation directions and an optical scanner which shifts the propagation direction on the same waveguide. CONSTITUTION:The optical modulator 5 makes on-off modulation according to whether the propagation of the laser light of a laser light source 2 is changed or not. The light changed in the direction is discarded. The optical scanner 6 makes scanning by shifting the propagation direction of said light by an arbitrary desired quantity from a certain specified direction. The modulator 5 and scanner 6 are formed on the same waveguide. The laser light is made into guided light by an incident coupler 3 and is emitted from an exit coupler 7 via the modulator 5 and the scanner 6. Since the optical modulator 5 does not turn the laser driving on and off, the fluctuation in the wavelength is obviated and the guided light is emitted at the angle exacter than the angle of a diffraction grating. The separate execution of the modulation and scanning is thus possible.

By this, a spray washing in which washing is made at constant pitches and any unwashed part is not left is enabled. As the other means, a distance adjusting means to adjust a distance between the side surface treatment device and the body is provided so as to enable the forward and backward movements of the side surface treatment device relative to the body. Thus the washing of the side surfaces of the body is always enabled under constant conditions, and high quality washing can be performed.

IPC: H01L21/8247
Filed: 1990-07-12
Abstract: PURPOSE:To make the surface of a semiconductor substrate clean by a method wherein a second conductive film, a second insulating film and a first conductive film in a first element region are etched and removed. CONSTITUTION:A single-layer gate electrode is formed by making use of first etching-resistant films 19a, 19b as a mask; after that, the first etching-resistant films 19a, 19b are removed before executing a patterning operation to form a two-layer gate electrode.
