Title: Brake system
Inventor: TAKESHIMA SADAO
IPC: B60T13/52
Filed: 1995-06-08
Abstract: PURPOSE: To generate large braking force with small brake operation force by determining where the relation of real input-to-output relation of a negative pressure boosting device exists in actuation ranges and non-actuation ranges of a first and a second switching valve, and actuating the switching valves based on the result of determination for a relatively long period. CONSTITUTION: When a vehicle runs, detection signals of a stepping force gauge 22 and a stroke sensor 23 of a brake pedal 2 and a liquid pressure pickup 13 for brake liquid pressure are inputted to a controller 24, and a first and a second switching valves 17, 19 to control a negative pressure boosting device 3 are controlled based on the input signals. In this case, gradient of an actuation boundary line of the first switching valve 17 as a vacuum valve is set to be larger than a gradient α of input/output static characteristics of the negative pressure boosting device 3, and the gradient of an actuation boundary line of the second switching valve 19 as an open air valve is set to be similar to the gradient α.  It is determined where pedal stepping force-master cylinder liquid pressure relation exists in actuation ranges and non-actuation ranges of the switching valve 17, 19, and the switching valve 17, 19 are controlled based on the result of determination.

Title: Method for recovering arsenious acid and gypsum
Inventor: MICHIKI HIDEYUKI
IPC: C01F11/46
Filed: 1982-08-16
Abstract: PURPOSE:To recover arsenious acid and gypsum without requiring concn. nor cooling in a state contg. sulfuric acid by adding ammonia to an acidic soln. of sulfuric acid contg. metallic sulfates and arsenic compounds, separating the resulting precipitate, calcining it, and adding a Ca compound to the remaining soln. CONSTITUTION:Waste gas contg. dust, SOx, arsenic compounds, etc. is scrubbed with an acidic soln. of sulfuric acid, an NH4OH is added to the resulting acidic soln. of sulfuric acid contg. metallic sulfates and arsenic compounds to coprecipitate the hydroxides of iron and other metals with the arsenic compounds. An iron compound may be added before adding the NH4OH. The precipitate is separated from the soln., dried, and calcined to volatilize and recover arsenious acid. A Ca compound is added to the remaining soln. contg. (NH4)2SO4 to cause double decomposition of the (NH4)2SO4, forming gypsum and NH4OH. The sypsum is separated, and the NH4OH is reused in the stage for coprecipitating the hydroxides of iron and other metals with arsenic oxide. The arsenic compounds are efficiently recovered as arsenious acid, and the sulfates can be recovered as gypsum having a low arsenic content.

Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To stably execute the control of molten metal surface level in a steady state by raising the molten metal surface level as quickly as possible without overshooting, when twin roll type continuous casting equipment is started automatically. SOLUTION: When pouring of molten metal 4 is started, a flow rate adjusting means is fully opened, and the molten metal 4 is poured at high speed. When the molten metal 4 is poured to a first molten metal surface level in a molten metal pool part 5 while preventing the development of the overshoot by narrowing the flow rate adjusting means to a predecided regulated opening degree, a first molten metal surface level control is executed in which the molten metal is raised to a second molten metal surface level. Then, while restraining the rise of the molten metal surface level in the molten metal pool part 5, the molten metal is raised to the ordinary level, and successively, the second molten metal surface level control for keeping the steady state level constant is executed.  In this way, the cast starting work from the start of pouring the molten metal to the moment the prescribed molten metal surface level is reached can be fully automatized.

Title: Manufacture of semiconductor device
Inventor: TAKADA TOSHIAKI
IPC: H01L21/331
Filed: 1979-11-02
Abstract: PURPOSE:To obtain high yields by changing impurity concentrations in a high temperature atmosphere with the lapse of time when an insulating film on a semiconductor substrate is converted into a glass layer. CONSTITUTION:An insulating film is formed on a major surface of a semiconductor substrate. The insulating film is converted into a glass layer by exposing the insulating film in a high temperature atmosphere including impurities and the impurities are diffused into the semiconductor substrate from the glass layer. In this process, impurity concentrations in the high temperature atmosphere are changed with the lapse of time. For example, the first impurity concentration at the temperature atmosphere of 950 deg.C including a phosphorus impurity is raised to 3,000ppm. Then, the impurity concentration is lowered to 2,000ppm to form an N type region. An oxide film on the major surface is instantly converted into a phosphorus glass layer by impurity diffusion at a high concentration by such a process. Therefore, the impurities are uniformly diffused even if the phosphrus impurity concentration is as low as 2,000ppm. So, the impurities are hard to be affected by a high temperature atmosphere state and high yields will be obtained.

Title: Vibrating motor
Inventor: SUGIMORI MASAMI
IPC: H02N2/00
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To provide a very efficient standing wave-type vibrating motor which has a wide operating frequency range by judging whether a motor is operating in a higher or a lower frequency band than a peak frequency and determining the direction that the frequency is shifting. SOLUTION: When a microcomputer 1 sends a signal for outputting a high-frequency signal to drive a vibrating motor to a high-frequency generator 2, the high-frequency generator 2 generates a set high-frequency signal and sends it to an amplifier 4 and a phase shifter 3 which shifts the phase of the signal by 90 deg.. Then, the phase shifter 3 sends a signal to an amplifier 5 and the outputs of the amplifiers 4, 5 are input to electrodes 74a-74c of a vibrating motor 8 through coils 6, 7. An encoder 9 serves as a position detector and measures a relative position of an object which makes a relative movement with the motor due to vibrating force of the motor and then sends a signal corresponding to the position to the microcomputer 1.  As a result, even if the motor is operating in a higher or a lower frequency band than a peak frequency, the speed of the motor can be controlled properly and a degree of freedom in driving control and an efficiency can be increased.
