Title: Method for controlling operation of blower for aeration
Inventor: HIBINO ATSUSHI
IPC: C02F3/12
Filed: 1989-07-19
Abstract: PURPOSE:To save the energy of a blower operation by controlling blowers to 3 stages; low, middle and high speed revolutions in order to maintain a DO(dissolved oxygen) value within upper and lower limit values by utilizing a DO sensor with upper and lower limit alarms mounted in an aeration tank. CONSTITUTION:The DO value in the aeration tank 1 is measured by the DO sensor 2 with the upper and lower limit alarms and is sent to a DO sensor body 3. The blowers 5 are controlled in revolution at a certain specified revolving speed (middle speed) by an inverter 4 while the DO value exists between the upper and lower limit values preset in the DO sensor body 3. An upper limit alarm signal is outputted from the DO sensor body 3 when the DO value exceeds the upper limit value. The inverter 4 lowers the revolving speed of the blowers 5 by this signal. The blowers 5 are similarly revolved at the high speed when the DO value falls below the lower limit value. The revolving speeds of the blowers are thus controlled in three stages by load fluctuations and, therefore, the rate of saving the energy is improved.

Title: Steel excellent in solubility in water and method for controlling concentration of inhibitor using this steel
Inventor: YUKI HIDEAKI
IPC: C22C38/00
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To obtain a steel excellent in solubility in water by prescribing the compsn. of elements in the steel. SOLUTION: This steel contg., by weight, 0.5 to 18% Mn and 0.02 to 0.3% S, and in which the ratio of Mn/S is regulated to >=4 has high solubility in water. This is because a large amt. of MnS is formed in the steel, and with the MnS long stretched by hot rolling as the starting point, rust is generated to form a porous rust layer inferior in adhesion to the surface of the steel and hard to constitute a barrier to dissolved oxygen, which positively deteriorates its corrosion resistance, and a new face is always revealed on the surface of the steel. Namely, this steel has characteristics of being easy to rust.  In the case a test piece made of this steel is arranged in a soln. added with an inhibitor, the test piece starts to rust previous to the steel member of the device treating the soln., and therefore, reduction in the concn. of the inhibitor can easily and surely be detected before the use of the device itself is made impossible.

Title: Beam adjustment method for optical pickup
Inventor: YAMADA TAKATOSHI
IPC: G11B7/08
Filed: 1994-07-18
Abstract: PURPOSE:To prevent spike-shaped noise from appearing in a tracking error signal by moving the position of a grating element arranged between a semiconductor laser element and a collimator lens in the direction of an optical axis. CONSTITUTION:By moving the position of the grating element 21 arranged between the semiconductor laser element 20 and the collimator lens 22 in the direction of the optical axis, a beam spot outgoing from the semiconductor laser element 20 and incident on a light receiving element receiving a light beam of the outside is moved on the light receiving element. In such a case, since an offset occurs in the tracking error signal according to the beam spot of the outside on the light receiving element, by moving the grating element to the proper position, the beam spot of the outside of the other side is deviated by the same amount in the reverse direction, and a return light quantity corresponding to the other side beam spot is reduced by the shortage of the return light quantity. Thus, the offset in the tracking error signal is eliminated, and the noise is prevented.

Title: Semiconductor laser driver
Inventor: ASADA KENICHIRO
IPC: H04N1/113
Filed: 1990-07-16
Abstract: PURPOSE:To improve the picture quality by varying a power conduction time of a semiconductor laser in response to a picture data so as to combine pulse width modulation and power modulation. CONSTITUTION:The power of a laser diode 107 depends on a flowing current thereto. For example, let a power P1 for a current i1, a power P2 for a current i2 and a power P1+2 for a current i1+i2, then the laser diode 107 is lighted by a power P1, P2 or P1+2 in response to signals S1, S2 generated by a power changeover circuit 402 for only a time of a PWM signal. Thus, pulse width modulation plus power modulation is processed. Thus, since the pulse width modulation and the power modulation are combined in the driver, the quality of picture is improved.

IPC: G04G7/00
Filed: 1981-11-24
Abstract: PURPOSE:To make time correction automatically after a power failure by providing a time correcting device which sends pulses of higher frequency than normal to a slave timepiece when the power source recovers. CONSTITUTION:A master timepiece operates by a no-break power source such as a battery to generate pulses, a slave timepiece is powered up by a commercial power source and driven by said pulses to hold current time if the commercial power source has a power failure, and a time correcting device sends pulses of higher frequency than said pulses to the slave timepiece in case of a power failure. For example, while the commercial power source is normal, the 1MHz output of an oscillator 1 is converted by a counter 2 into a 10Hz signal, which is further converted into a 1Hz signal by a counter 3 to obtain a second signal to be supplied to a transmitting circuit 16 through gates 13 and 15. When the power failure recovers, the 10Hz output of the counter 2 is supplied to the transmitting circuit 16 by a power source signal 6 and through the operation of circuits 7-15 to make time correction.

Filed: 1981-11-24
Abstract: PURPOSE:To obtain the junction element which can well cope with reproducibility and stability, by fusing, bonding, and sealing the glass of an outer container and the glass of Dumet wires. CONSTITUTION:A plate electrode 13 is welded and fixed to the tip of the Jumet wire 14, and a glass ball 16, made of the same material as that of the glass of the outer container 11, is attached. A needle electrode 12 is bent in advance so as to impart elasticity, and welded and fixed to the tip of the Dumet wire 15. A glass ball 17' made of the same material as that of the glass of the outer container 11 is attached. The glass balls 16' and 17' are made to be of a circular cylinde type, and the Dumet wires 14 and 15 are inserted in the centers thereof. The needle electrode 12 and the plate electrode 13 are inserted from both ends of the outer container 11 so as to face each other. With the junction pressure being kept at a desired state, only the part, at which the glass balls 16' and 17' are contacted with the outer container 11, is heated. The glass balls and the outer container 11 are melted and bonded with this heating. When the outer container 11 is hermetically sealed, the glass balls 16' and 17' simultaneously become the glass 16 and 17 so as to form a unitary body with the outer container 11. Therefore, the element is mechanically stabilized, and the junction pressure is securely maintaned.

Title: Non-pollution heating method
Inventor: SUZUKI TOYOJI
IPC: F23C99/00
Filed: 1985-08-26
Abstract: PURPOSE:To provide a thermal effect double that of the conventional system by a method wherein nitrogen in the atmosphere is expanded, shrinked to a specified volume and then circulated and expanded. CONSTITUTION:In a combustion space 3 in a furnace of a rotary fuel igniter device 2 provided with a fuel injection inlet 1, nitrogen is expanded and substantially rotated in a tangential direction after a thermal reaction of rotary combustion fuel with oxygen and directed toward the center of the circle, the expansion is reversed in the space in the furnace to cause the flame to be shrinked and merged. At the center of the furnace, the fuel is expanded by 314.6 times the ratio of circumference to its radius (to compensate for 1/314.6 times the ratio shrinking). However, due to a difference in the direction, the rotation becomes a circular rotation. With this arrangement, a single combustion changes to plural combustion, and the atmosphere and the fuel are injected against their passing resistance at the center of the furnace, thereafter the nitrogen is expanded and merged in a restricted space to cause a complete combustion, thus the fuel and the atmosphere are saved. These multiple rotations provide the combustible powder fuel, alcoholic oil fuel, water decomposition gas methane natural gas, or the like with heating ability double that of the conventional system.
