Title: Biological treatment device for waste water
Inventor: KATAOKA KATSUYUKI
IPC: C02F3/06
Filed: 1978-06-02
Abstract: PURPOSE: To treat waste water efficiently and economically and make the final precipitation pond needless by partitioning a treatment tank by a partition wall into an aeration zone and a solid-liquid separation zone and providing the latter zone with a filtration portion comprising a perforated water-permeable member.  
     CONSTITUTION: A treatment tank 1 is partitioned by a partition wall into an aeration zone A and a solid-liquid separation zone B. With a treated water such as sewage sludge fed to the aeration zone A from an inflow pipe 7, biological treatment is conducted in the circulating flow of a particle medium so as to remove BOD in the treated water. Then the treated water flows into the zone B, where the SS are filtrated by a filtration portion 4 comprising a perforated water-permeable member such as a filter cloth in the form of a rotary disc, and the clean treated water overflows from the tank 1. The SS caught by the filtration portion 4 are cleaned in the forced water flow in a water flow suction portion 5. Because the waste water containing fine SS at high concentration is treated efficiently, the running cost is  reduced and the final precipitation pond is made needless.

Title: Position detector for rotary tone arm
Inventor: YAMADA JIROU
IPC: G11B3/095
Filed: 1983-04-15
Abstract: PURPOSE:To improve the accuracy for position detection of a tone arm by detecting both rise and fall of a pulse. CONSTITUTION:A shift of a tone arm main body is detected by a photocoupler, and a pulse 10 is generated. This pulse 10 is inputted into a rise/fall detecting circuit 8. Thus the rise of the pulse 10 is detected by gates (a) and (b), a resistance R1 and a capacitor C1. While the fall of the pulse 10 is detected by gates (a) and (c), a resistance R2 and a capacitor C2. These two detection outputs are added with each other through a gate (d) to obtain a pulse 11. This pulse 11 is supplied to a pulse counter 9. In such a way, detecting both rise and fall and counts the obtained pulse 11 by the pulse counter 9, so the detecting accuracy can be improved for position of a tone arm.

Inventor: OOTSUBO AKIO
IPC: C09D5/23
Filed: 1981-05-03
Abstract: PURPOSE:To obtain a recording medium having a smooth surface with good vertical orientation and high output, by using fine particles of a specific single magnetic domain for a vertical recording layer and using a two-layer medium including a high-permeability layer for the lining of the said vertical recording layer along with an oriented electromagnet having small  rugged parts on the surface of the magnetic pole to perform current transformation and  degaussing. CONSTITUTION:A vertical recording layer is formed with hexagonal Co globular fine particles  (preferably hexagonal particles of Co-Ni alloy containing <=30wt% Ni to enhance the weather  resistance, oxidization resistance) or fine particles having the form anisotropy of Fe, etc. with  1.6-1.4 axis ratio and having a small reduction degree of vertical orientation regardless of  calendering. A two-layer medium containing a layer made of the multimagnetic domain size  particles having high permeability equal to or higher than that of the said vertical recording  medium is used for the lining of this recording layer, and small rugged parts are formed on  the magnetic pole surface at the side where an electromagnet for vertical orientation has contact and orientation. At the same time, AC degaussing is carried out by an electromagnet with  the space of the magnetic pole surface increased gently at the tape flow-out side. As a result,  a magnetic layer having no rugged part during vertical orientation is obtained, and at the  same time the return of orientation due to a counter magnetic field is prevented to obtain an excellent magnetic recording medium.

Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a thickness controller for tandem rolling mills with which the thickness deviation of a material to be rolled is dissolved without deteriorating rolling balance and whose control range is expanded than that of conventional controllers. SOLUTION: The thickness deviation is determined from the measured thickness of the material to be rolled and the target value with a thickness gage 17 and the thickness deviation is divided by the target thickness with an analog divider 20. The speed of a motor 15 is controlled corresponding to the output of the analog divider 20 with a PID controller 41 and the speed control of a work roll 9 is executed. A part of the output of the PID controller 41 is distributed to the PID controllers 48-50 with each ratio setting device 42-44 and these distributed values become the target values for controlling the PID controllers 48-50. The speed of each motor 12-14 is controlled based on the each target value of control, so the speed of the work rolls 6-8 is controlled.  Each control gain of the PID controllers 41, 48-50 is successively changed corresponding to the output signals of transporting time computing elements 51-54.
