Title: Treatment of waste water
Inventor: SEKIKAWA YASUHIRO
IPC: C02F1/28
Filed: 1980-05-09
Abstract: PURPOSE: To use a treating agent which forms insoluble deposits by reacting with the components in waste water, with good efficiency, and improve the quality of water after the treatment by adding said treating agent in the form of powder, grains, lumps or slurry, to the waste water, then subjecting the waste water to solid-liquid separation.  
     CONSTITUTION: Raw water 4 and a treating agent 5 such as slaked lime are introduced into a reaction tank 1, and are caused to react with stirring, wherein if the treating agent is added in the form of powder, grains, lumps or slurry, reaction takes place on the surfaces of the undissolved treating agent particles, thereby depositing insoluble deposits on the surfaces. Thence, the reacting liquid is subjected to solid-liquid separation, and part of the separated solids are sent by a pump P to a grinding machine 3, where they are ground, thence they are returned as return slurry 6 into the tank 1. The unreacted treating agent contained in the slurry by the grinding exposes, and disperses and dissolves in the liquid, thus reacting with the unreacted components in the waste water of the tank 1. The separating water in a separating tank 2 is released as treated water 7.

Title: Optical system for correcting scanner
Inventor: HOSAKA YASUO
IPC: H04N3/02
Filed: 1979-05-21
Abstract: PURPOSE: To obtain stable timing pulses even if any dust and the like are produced on the correcting slit by making the sectional shape of the correcting laser beam lognitudinally long in the direction nearly perpendicular to the scanning direction of the laser beam.  
     CONSTITUTION: In the optical system for correcting scanner, a cylindrical lens 28 of, for example, focal length 700mm is disposed between a focusing lens 23 and galva mirror 24. Disposing the main axis of said lens 28 in the direction perpendicular to the beam deflecting face by the galva mirror 24 makes the beam spot produced in a correcting slit 25 slender and lets it be intensity-modulated according to the slit. This beam is then made to an electric signal by a photo detector 27. Now, if it is assumed that the slit width of the correcting slit 25 is 40μm, the beam spot 30 becomes 40μm in the scanning direction A and 300μm in the direction perpendicular to A. The electric signal obtainable from the photo detector does not become 0 even if dust 32 exists and therefore the effect of the dust may be eliminated and the stable timing pulses obtained by performing waveform shaping.

Abstract: PURPOSE:To omit the lock mechanism of a magnetic head and to attain the cost reduction by specifying the mass unbalance moment of a rotary bearing of an assembly of the actuator mechanism. CONSTITUTION:A magnetic head 2 is attached to an end of an actuator arm 3 supported by a rotary bearing 4, and the other end of the arm 3 has a contact with a capstan 5 via a metallic band 6. Then the mass unbalance moment M of an assembly round the bearing 4 is decided as shown by an equation, where TD, K, R1 and R2 equal to the non-energizing torque of a drive motor, the level of disturbance, the radius of the capstan 5 and the distance between the bearing 4 and the fixed part of the band 6 respectively. Therefore it is prevented that the head 2 moves to have a contact with a magnetic disk 1 even through the maximum (30G) disturbance is applied. As a result, a head lock mechanism can be omitted to attain the cost reduction with an actuator mechanism of a magnetic head.
