Title: Mechanical and chemical polishing
Inventor: KARAKI TOSHIROU
IPC: H01L21/306
Filed: 1979-10-11
Abstract: PURPOSE:To eliminate the contamination of the back surface of a wafer formed with an SiO2 film on the entire surface by dipping it in an acidic solution and to precisely machine the front surface of the substrate by adhering the wafer to an adhering plate by an adhesive and polishing the upper surface of the substrate in a liquid in which a working agent is suspended. CONSTITUTION:An Si wafer is dipped, for example, in an H2SO4+H2O2 liquid to form an SiO2 film on the surface thereof, and is adhered onto a ceramic plate 3 with an adhesive 2, and is polished on the surface of the wafer 1 with a working agent of colloidal silica suspended in an alkaline solution having pH of 11 with an SiO2 of 100-200Angstrom  thick as an example. Thus, the surface of the wafer is eliminated from recess or wavy shape and is formed in a highly formed surface. The back surface of the wafer is protected by the SiO2 film to elliminate corrosion and contamination, and the yield of machining the wafer can be consequently improved.

Title: Method for superfinely and uniformly applying separation agent mgo for annealing and crusher for the agent
Inventor: YAMOCHI KEISUKE
IPC: C08F210/02
Filed: 1992-05-22
Abstract: PURPOSE:To form a good-quality glass coating film and to impart a good magnetic characteristic by coating the surface of a steel sheet with a slurry of the calcined MgO particles in water. CONSTITUTION:The main component MgO of the separation agent for annealing reacts with an oxide film formed in decarburization annealing and consisting essentially of SiO2 to form a glass coating film (2MgO+SiO2 Mg2SiO4). At this time, the separation agent consisting essentially of MgO has a great effect on the glass coating film in the same way as secondary recrystallization. The MgO is formed from the primary particles of the crystal of magnesium hydroxide, magnesium carbonate, basic magnesium carbonate, etc., having 0.2-5mum average diameter and calcined at 700-1500 deg.C in the batch type furnace or rotary kiln. The particles are suspended in water to form a slurry, and the slurry is treated by an ultra-fine grinder for a short time and applied on the surface of a steel sheet. A lower grinding stone 3 is rotated by a motor 5, the clearance with an upper grinding stone 2 is controlled to 50mum, and the slurry is treated at a rate of 30l/min.

IPC: H01L29/73
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To increase the withstand voltage by suppressing the depletion layer extended from a collector region in case it is impressed with high voltage by a method wherein a high concentration n<+> guard region is formed between a collector region and a p<+> emitter region encircled by the collector region through the intermediary of n<-> base region. SOLUTION: A high concentration n<+> guard region 20 is formed between a p<+> collector region 16 and a p<+> emitter region 17 encircled by a p<+> emitter region 17 encircled by the p<+> collector region 16 through the intermediary of a base region. Thus, a depletion layer 21 extended from the collector region 16 in case it is impressed with a high voltage is spread as shown by a fine line so that the spread in the emitter region 17 may be suppressed by the n<+> guard region 20 thereby enabling the withstand voltage to be increased. Furthermore, since the current impression efficiency between collector and emitter is decreased by providing n<+> guard region 20 so as to reduce the DC amplification factor thereby enabling the withstand voltage between collector and emitter to be increased.

Title: Operation of filter press
Inventor: IIJIMA YOSHINARI
IPC: B01D25/12
Filed: 1981-08-22
Abstract: PURPOSE:To enhance the efficiency of a filter chamber volume changeable type filter  press, by a method wherein a cake formed by a raw liquid pressure introducing process  is pressed to be collected to the center part of a filter chamber and the cake formation due to pressure introduction of a raw liquid is carried out by a filter cloth on  which a cake layer is not formed at all times. CONSTITUTION:A raw liquid is supplied under pressure from a supply valve 11 and a  supply port 12 to be filtered by a filter cloth 7 and the filtrate is discharged from a discharge port 10 along a grid groove 9. When a cake reaches a predetermined thickness,  a valve 11 is closed and a filter plate 5 is pressed by a press plate 4 to deform an elastic outer peripheral framework 6 and, thereby, a filter chamber 8 is narrowed to mechanically dehydrate said cake. In the next stage, the press plate 7 is returned to be  easily released from the filter cloth 7 and the cake 13 is formed at the center of the filter chamber 8. When the valve 11 is opened again and the raw liquid is supplied to the  filter chamber  8, said raw liquid is easily filtered because the inner peripheral wall of  the filter chamber 8 is present in such a condition that the filter cloth 7 is exposed and  the cake 13 is not collapsed within a short time. Mechanical dehydration is again carried out and these operations are repeated to easily increase the amount of the cake in  the filter chamber 8.

Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To optimally control the dropout compensating sensitivity by making a reproduced FM wave input level and limiter level variable, in accordance with a white noise width after the detection of a video signal. SOLUTION: The envelope curve detection of the white peak noise is performed by a signal level detection circuit 13 from the output signal of a reproduced FM wave-detecting circuit 10. A preset reference voltage is compared with the difference signal between an envelope curve signal, coming from the signal level detecting circuit 13 and the video signal coming from a noise canceller circuit 12 by a white peak width-detecting circuit 14 to calculate the difference. By a control signal generator 15, a control signal voltage (a) is transmitted to a reproduced FM equalizer circuit 17, and control signal voltages (b), (c) are transmitted to a dropout compensating circuit 18 respectively, in accordance with an output level of the white peak width-detecting circuit 14.  By this procedure, the dropout compensating sensitivity is optimally controlled, and the deterioration in image quality is suppressed even in the case a magnetic tape having coarse magnetic density is used.

Title: Image data processor
Inventor: INOUE YOSHIAKI
IPC: G06T5/00
Filed: 1994-06-14
Abstract: PURPOSE:To prevent tone jump generated on a dot image. CONSTITUTION:A calibration section 44A calibrates image data S in 8 bits based on the output condition of the dot image to generate calibrated image data G in 12-bit. A synthesis section 74 adds n-bit random number data Ra to the low-order of threshold data Pa in 10 bits outputted from a threshold data storage section 50A to generate threshold data I in 12 bits. They are compared with a data comparison section 46 to generate binary image data Ha. Since the gradation number of the threshold data I is equal to gradation number of the calibrated image data G in the binary image data Ha, tone jump caused by it that the number of gradation of threshold data is substantially less than the number of gradation of the image data is prevented. Since the calibration image data G are used, the tone jump generated by the change in the dot area rate depending on the output condition is prevented.
