Title: Cooling method of continuous casting billet
Inventor: MITSUZUKA MASASHI
IPC: B22D11/12
Filed: 1983-09-09
Abstract: PURPOSE:To perform economically direct rolling of a continuous casting billet in the stage of cooling slowly a continuous casting billet by mist cooling in secondary casting of said billet and hot rolling continuously the billet by utilizing the quantity of the heat possessed by converter waste gas to form the mist. CONSTITUTION:A molten steel 7 in a mold 8 of a continuous casting device is continuously cast and is slowly cooled by a secondary cooler 6. The cooled steel is rolled directly by a hot rolling mill without generating surface cracking so that the excessive consumption of heat energy by cooling and reheating during the cooling is eliminated. The cooling by mist is optimum for the slow cooling of a continuous casting billet 9 by which direct rolling is made possible without partial cooling and without generation of a defect such as cracking on the surface of the continuous casting billet. The high temp. waste gas from a converter 1 is passed through a discharge duct 2 to heat the water in the boiler tubes 3 around the duct to >=150 deg.C. The heated water is stored in a hot water storage tank 4 and is supplied to a carburetor 5 by which superheated steam is generated. The cooling water is atomized to form the mist by the superheated steam and therefore the direct rolling of the continuous billet is extremely economically accomplished without requiring separately fuel, etc. for forming the mist.

Abstract: PURPOSE:To record a still picture with least shifting without using any special shutter by adding a pulse-width modulation circuit and a selection switching means to the electrical circuitry to obtain a normal automatic diaphragm action mode and shutter action mode. CONSTITUTION:When a selection switching means 10 is turned to a contact (a) and a comparator circuit 8 is connected with an automatic diaphragm 3, the output of the circuit 8 is supplied to the drive coil of the diaphragm 3 to control the diameter of the diaphragm 3 so that a D.C. signal 7 becomes equal to a reference voltage Vr, and a proper exposure is obtained. Further, the output of a pulse-width modulation circuit 11 added to the circuit, is inputted to the diaphragm 3 instead of the output from the comparator circuit 8. This circuit 11 outputs the pulse string of a width corresponding to the output of the circuit 8 that is synchronizing with a vertical synchronizing signal V-sync. The circuit 11 is connected with the selection switching means 10, but is turned to be connected to the diaphragm 3 when the contact is turned to b-side.

Title: Semiconductor device
Inventor: ONO YASUYUKI
IPC: H01L21/316
Filed: 1987-07-01
Abstract: PURPOSE:To prevent the development of voids in an Al wiring layer and the decrease in hot electron resistance, by using a film, whose component gradually changes into silicon nitride from silicon oxide nitride as a surface is approached, as a protective film on the Al wiring layer. CONSTITUTION:A protective film 7, whose component gradually changes into silicon nitride from silicon oxide nitride as a surface is approached, is formed on an Al wiring layer 6. The protective film 7 is formed as follows. The temperature of a semiconductor substrate 1 is kept at 200-300 deg.C by a plasma CVD apparatus, which has facing electrodes in a vacuum container. As film forming gases, silane, ammonia and nitrogen are introduced at the ratio of 17:6:15, respectively. In addition, nitrogen suboxide gas is introduced. At this time, the flow rate of the nitrogen suboxide gas is made to be 0.6l/min. The film, whose film stress is almost 0 dyn/cm<2> is formed. Thereafter, the flow rate of the nitrogen suboxide is gradually decreased (e.g., linearly at the rate of 0.03l/min for every minute). Thus the silicon oxide nitride film is formed. The film, in which the amount of the nitrogen suboxide is 0l/min, i.e., the silicon nitride film, is grown as the uppermost layer.

Filed: 1980-11-26
Abstract: PURPOSE:To lower treatment costs by making the slurry projection width and pressure of an abrasive cleaning device variable, and making the injection and stopping of arbitrary number of the steps of the sprays provided to a pickling device possible in a process for pickling strip surfaces after their abrasive cleaning. CONSTITUTION:A strip S is removed of scale by the abrasive grain slurries projected from the nozzles of an abrasive cleaning device 10. When at this time the strip width decreases, the projection width is adjusted by turning, for example, a header 11. The energy to be projected is controlled to desired values by changing the pressure of high pressure water.

Filed: 1994-07-19
Abstract: PURPOSE:To remove specific particles from mixture particle beam by choosing such material as is easy to attract particles desired to be removed as a material for a collimator and providing multiple holes where the ratio of length L against diameter D, L/D, is large enough. CONSTITUTION:For example, if the only CF2 is removed from mixture particles 1 of CF2 and CF3 1 generated in CF4 plasma, for obtaining only collimated CF3, SiO2 whose attraction coefficient to CF2 is large is chosen as a material of a collimator 3, and many holes 4 whose L/D is large is provided to it for a multi-aperture structure. Making the particles 1 generated in-plasma pass through the collimator 3 thus obtained before reaching a sample, CF2 particles 5, conventionally prevented etching by accumulating in deep holes, are attracted to an inner wall of the collimator 3 for removal, so that, particles which reach the sample are only CF3 whose attraction probability is low, for smooth etching with the deep holes whose diameter is small.

Abstract: PURPOSE:To suppress tripple-transist-echo by forming the distance of surface acoustic wave propagation of two corresponding transducers as l+lambda/4, where (l) is the surface acoustic wave propagation distance between the two adjacent transducers and lambda is the wavelength. CONSTITUTION:The surface acoustic wave propagation distance of the two corresponding transducers 21-22 and 21-23 is formed as l+lambda/4, i.e., the propagation distance difference is formed as lambda/4, where (l) is the surface acoustic wave distance between the two transducers 11-12 and 11-13 and lambda is the wavelength. Thus, the propagation distance difference is lambda/2 as to the re-reflection wave and the phase of tripple-transist-echo (T.T.E) is inverted, then no T.T.E is produced at an electric terminal 38.

Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To make it possible to give variety to display contents with small video data by permitting to start displaying video data not only from the beginning but from the middle when background noises are displayed along with a performance of KARAOKE melody. SOLUTION: When BGV(background video) is reproduced during a performance of a KARAOKE melody, it is determined according to the contents of a BGV selection register 12a whether BGV data to be reproduced in parallel are selected from a BGV disk 1 or a BGV disk 2 and it is also determined according to the contents of the BGV selection register 12a whether the selected BGV data are reproduced from the beginning or from the middle. The contents of the selection register 12a are updated in each KARAOKE performance of one piece of music. Therefore, even a same video data provides a video with different atmosphere if the reproduction is started from a different position. Moreover, if a reproduction time of a video data is longer than a performance time of a KARAOKE melody, it is possible to make use of a second half part of video which is usually not unutilized.
