Title: Disposal by activated sludge
Inventor: HOSOKAWA SHIYUUJI
IPC: C02F3/34
Filed: 1978-03-07
Abstract: PURPOSE: To permit of a high-BOD run, by adding nitric acid or nitrate to waste water to be disposed of and generating nitric acid respiring bacteria in a decomposition vessel and decomposing and removing the pollutants in the water by the  bacteria.  
     CONSTITUTION: The nitric acid or nitrate is added to the waste water to adjust its pH level to 6 to 9. Then, the water is introduced into the decomposition vessel so that the water is stirred. At that time, the nitric acid respiring bacteria are generated in the waste water to biologically decompose and remove the pollutants in the waste water. Since oxygen necessary for the biological decomposition of the pollutants is produced by the decomposition of the nitric acid or nitrate, it is not required to perform aeration in the decomposition vessel. The waste water is thereafter treated by aerobic activated sludge so that the waste water is purified to a high degree.

Filed: 1989-02-03
Abstract: PURPOSE:To provide the title method so designed that at the initial stage of pulling, a raw material of lower dopant concentration than that for raw material to be fed in the steady state is fed to the outer crucible in such an amount as to be more than the decreasing amount due to the pulling, thereby suppressing the dopant concentration unevenness at the initial stage of pulling to a minimum. CONSTITUTION:A raw material and a dopant are fed into a duplicate crucible provided with mutually communicating outer and inner crucibles, being melted and made smaller in amount than that of the molten material W in the crucible in the steady state and also made higher in concentration than that C of the dopant in the inner crucible in the steady state. Thence, at the initial stage of pulling, a raw material with its dopant content <=KC (k is segregation coefficient) is fed, via a chute, to the outer crucible in such an amount as to be more than the decreasing amount of the molten material in the inner crucible due to the pulling to attain the dopant concentration ratio for both the inner and outer crucibles to the target value. And in the steady state pulling, a raw material with dopant content of KC is fed to the outer crucible in the same amount as the decreasing amount of the melt due to the pulling, thereby pulling single crystal concurrently.

Title: Optomagnetic recording system
Inventor: OKAMURA SHIROU
IPC: G11B5/02
Filed: 1983-02-17
Abstract: PURPOSE:To attain the recording with saturation in both one and other direction depending on the strength of laser by heating a tape near the Curie point with a laser beam or the like modulated by a signal so as to erase a part or all of magnetization and applying a static magnetic field in opposite to the said one direction to the heated point furthermore. CONSTITUTION:Figure shows the case that a magnetic field in opposite to the direction of the magnetic field of a tape 1 is applied to a position on the tape 1 in the vicinity where the laser beam is irradiated by placing a permanent magnet or an electromagnet 6 thereto. This magnetic field can be made variable depending on conditions such as type of material of the tape by using a battery 17 and a variable resistor 18. The intensity of the laser beam 4 becomes strong or weak depending on the signal; when the beam 4 is weak, the tape has a residual magnetic field close to the original saturation and when the beam 4 reaches a certain strength, the temperature rises near the Curie point, resulting that the residual magnetism is almost degaussed and the temperature of the tape is decreased by the magent 6 instead and magnetized in opposite direction. This reverse magnetization is designed to be maximized when the intensity of laser is maximum. In modulating the laser light by the signal in this way, the tape is recorded with magnetization up to positive and negative regions by using an analog signal. An optional magnetic substance having a Curie point is used for the recording medium used for this invention. The signal 5 has only to be processed nonlinearly in order to attain linear operation.

Title: Cathode-ray tube
Inventor: NAKAMURA KOJI
IPC: H01J29/86
Filed: 1985-02-12
Abstract: PURPOSE:To improve the brightness ratio at the circumference and in the center when employing a dark tint glass having low transmission factor by differentiating the curvature of outer face in the center of a glass panel from that of the outer face at the circumference. CONSTITUTION:The curvature RPI of the inner face of panel 2 is same in the center and at the circumference while the curvature RPE at the circumference of the outer face of panel 2 is same with conventional one. The curvature RQE in the center of the outer face of panel 2 is different from conventional one where the curvatures RQE and RPE are continued smoothly to be rotary symmetrical against the central shaft of panel. Consequently, the thickness T in the center of the outer face of panel 2 is thicker when compared with conventional one. When employing a dark tint glass, the brightness will drop by about 10% at the circumference but since the thickness in the center is increased by about 10%, the brightness will drop by about 10% in the center. Consequently, droppage of brightness at the circumference is cancelled to maintain the brightness ratio at the circumference and in the center at same level with that of clear glass.

Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To quickly activate a catalyst by calculating intake air flow and fuel injection amount per unit time on the basis of a fuel air ratio of engine outlet gas in cold starting, and the air fuel ratio of the gas entering catalyst to the exhaust cleaning catalyst. SOLUTION: Whether an engine is in the cold starting or not is judged in an ECU 40 on the basis of the result of the detection of a water temperature sensor 17 which detects the temperature of the cooling water in the operation of an internal combustion engine 1. When the result of the judgement is YES, whether the secondary air is supplied to an exhaust system or not is judged under the condition that the rotating speed NE determined on the basis of the output of the crank angle sensors 18A, 18B is, e.g. above 500 RPM, and it is judged that the cranking is completed. When the judgement is YES, the fuel injection amount to be increased and corrected corresponding to the secondary air supply amount is calculated.  Further, when the time after the starting of the engine is within a specific range, the intake air amount and the fuel injection amount per unit time are calculated, whereby an ISC valve 22 and a fuel injection valve 12 are controlled.

Abstract: PURPOSE:To make operation correspond to the handwritten character of a free character form for which a lot of deformed character forms are used by providing a feature point extracting means and a dividing point discriminating means and defining an outer-most point and a feature point as a dividing point. CONSTITUTION:For the detection of an end point, the end point is detected as a feature with that a distance l between starting and ending edges S and E in the end point is almost 1/2, for example, of a circumference with line width (d) as a diameter and that a change quantity in contour direction in the starting and ending edges S and E is almost 180 deg.. On the other hand, in a means to discriminate the dividing point of concavity/convexity structure from the end point and outer-most point, at first, the outer-most point end point are rearranged in the order of the contour point and depth vi of a contour between the two adjacent points is obtained. When the depth is larger than a rated value, the contour is decided as a concave part and the starting and ending edges of one concave part are defined as the dividing point. Thus, continuously convex sections go to one convex section together and the lowering of a reading rate or the increase of a standard pattern is prevented.

Abstract: PURPOSE:To prevent the vehicle from incurring a creep, etc. and as well to prevent the vehicle from moving backward upon starting on a slopping road, by utilizing a throttle valve opening degree control actuator in a cruis control device, also for automatic brake hold upon parking. CONSTITUTION:When a main switch S is turned on upon running, a CPU1 initiates operation so that a compartor 8 compares an actual vehicle speed signal (b) with a reference vehicle speed (c).

When the speed of a vehicle comes to zero by depressing a brake pedal, the CPU1 changes over the switch unit 3 onto the decelerator 5 side. Simultaneously, the reference vehicle speed signal (c) is turned into zero so that the actuator 2 automaically controls a brake operating mechanism to make the actual vehicle speed zero, and therefore, braking force may be held even if the brake pedal is released.
