Title: Turntable for recording carrier and its production
Inventor: ONO KOUTAROU
IPC: G11B3/60
Filed: 1981-07-30
Abstract: PURPOSE:To produce a turntable with high working efficiency, by using an Mg alloy or Mg as a material and arraying radially the forging lines toward the outer circumference from the center part. CONSTITUTION:A hot forging material of an Mg alloy or Mg is used to produce a turntable. A material billet is first put at the center upper part of a preheated forging mold 1. Then the billet is pressed by a punch 3 of a press forming machine and then extended into an even concentric circle to form a center flat part 4 and a thick fringe part 5. Then the punch 3 is pulled up and a molded product 6 is pulled out of the punch 3 by means of a mold releasing ring 7. Thus a forging process is through. Such product 6 undergoes a heat treatment and a mechanical working to be formed into a desired turntable. This table has highly stable rotations owing to the dense metallic crystal particles with no cavity and an even weight to the center of rotation.

Title: Automatic tracking device
Inventor: UMEHARA YOSHIAKI
IPC: G11B15/467
Filed: 1990-05-11
Abstract: PURPOSE:To prevent erroneous control in automatic tracking by detecting a regeneration signal level difference of a recording track corresponding to two recording heads caused by a characteristic difference between the recording heads and the deviation of the mount position of the recording heads as an off-tracking. CONSTITUTION:Recording track discrimination devices 11, 12 separate recording tracks with a different regeneration signal level due to a characteristic difference between recording heads 1, 2. Track counters 14 - 17 corresponding to each recording track supply a shared number of times when a regeneration signal is averaged and adders 18 - 21 and averaging computing elements 25, 26, 28, 29 supply the sum data of the regeneration signal corresponding to each recording track and the track counters 14 - 17. The track counter size discrimination devices 24, 27 discriminate the quantity of the counters 14 - 17 to discriminate by which track of regeneration signal the automatic tracking is to be implemented and the regeneration signal level difference is separated by the characteristic difference between the recording heads 1, 2. Thus, automatic tracking is implemented by the regeneration signal level difference only due to off-tracking.

Filed: 1983-06-29
Abstract: PURPOSE:To reduce a waste water treatment time by controlling externally the pH of an aqueous solution exposed and mixed so that the metabolic product is propagated in the state close to a natural state after a prescribed time is elapsed. CONSTITUTION:An aqueous solution is fed to a water tank 2 for a prescribed amount and the pH in the water tank 2 is measured timewise by a pH meter 4 while driving an exposure mixer 1, and a minimum pH MIN at a t1 of pH values until a time tx is stored in a storage section provided in a controller 10. Further, the pH MIN and a pH X while the exposure mixing is continued until the time tx are compared. When the pH X is equal to the pH MIN or lower than it, a solenoid valve 6 is opened by a command from the controller 10 so as to feed an acidic aqueous solution in a tank 3 into the water tank 2. When the pH of the aqueous solution in the water tank 2 is within the range of 6.5-7.0, the supply of the acidic aqueous solution to the tank 2 is stopped by the command of the controller 10. Thus, the pH keeps the value so far and the aqueous solution in the water tank 2 is discharged from a discharge pipe 13 while the metabolic product is regarded as being propagated in its maximum and fed to the next process.

Title: Dry-type desulfurization equipment
Inventor: NOZAWA SHIGERU
IPC: B01D53/02
Filed: 1979-09-20
Abstract: PURPOSE: To maintain the adsorption capacity at a constant level for a stable desulfurization operation by a method wherein the performance of semicoke, the adsorbent in the dry-type desulfurization process, is controlled by detecting the concentration of sulfur oxide in waste gas from the adsorption means.  
     CONSTITUTION: The semicoke produced by dry-distillation and activation of coal is used as the adsorbent in the dry-type desulfurization equipment. In this process, depending on the type of coal supplied, the dry-distillation condition in a rotary kiln 6 is controlled by a controller 10 based on the detection signal from a detector 8 which finds the content of sulfur dioxide in gas discharged from an adsorber 2. This maintains the performance of semicoke to adsorb sulfur oxide at a constant level and allows the stable exhaust gas desulfurization operation even if the type of coal changes.
