IPC: G11B15/43
Filed: 1992-01-27
Abstract: PURPOSE:To obtain a stable tape running and a tracking linearity provided with a compatibility by adjusting the tension distribution in the breadthwise direction of a tape-like recording medium while making the inclination of a guide post adjustable. CONSTITUTION:The device is constructed in such a manner that the guide post 14 is provided on a turning substrate 23 freely turnably supported by a shaft 22 arranged on a supporting substrate 21 and the turning substrate 23 us turned in accordance with the expansion/contraction of a piezoelectric element 24 to tilt the guide post 14. A repulsion in the direction of tape thickness on the upper and lower parts in the breadthwise direction of tape is detected by a pressure sensitive element to obtain an information of the tension distribution. Based on this information, the piezoelectric element 24 is compressed or expanded, then the inclined angle of the guide post 14 is adjusted so as to obtain the optimum tension distribution corresponding to each tape running mode. By this arrangement, the stable tape running is obtained even though the kind of tape or the running mode is changed, then the compatible tracking linearity is obtained.

Title: Separation of minerals in solution
Inventor: ODA MASASHI
IPC: B01D61/52
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of Na ions and Cl ions remaining in solution containing univalent ions and polyvalent ions. SOLUTION: Solution 1 to be separated which is wet oxidizing treated urine contains univalent ions such as Na, K, and Cl and polyvalent ions such as Ca, Mg, SO4 , and PO4 as mineral components. The solution to be separated 1 is mixed with solid or aq. solution of KCl 2 in a mixing tank 3. The solution 1 in the mixing tank 3 is fed to an electrodialysis device 4, and by electrodialysis, it is separated into demineralizecl liquid 5 from which univalent ions have been removed and univalent ion-concentrated liquid 6. When KCl 2 is added to increase the amount of K remaining in the demineralized liquid, the limiting concentration of univalent cations at which polyvalent ions starts to permeate can be lowered, compared with that before KCl addition.  In this way, the remaining amount of Na after electrodialysis is reduced, and in order to satisfy electric neutral conditions in the solution, Cl ions are reduced.

IPC: H02J3/18
Filed: 1978-02-07
Abstract: PURPOSE: To make an operation of the reactive power compensation at high speed further in high precision, with a detection speed of response not worsened, by detecting a current slope near the point, where an instantaneous value of the load current crosses over zero point, and an integrated value of the load current, from near the before said point to near the point of the load voltage π/2.  
     CONSTITUTION: A differentiated value of the current at the time t = T, where the current becomes zero, is obtained from a formula I. Secondly, an integrated value of the current from the time t = T to t = 1/4f is obtained from a formula II. In the formula, where ω is proper known number, if assuming the load voltage approximately constant, a reactive power of the load may be obtained from a difference between the differentiated value of the current at the time t = T and the integrated value of the current from the time t = T to t = 1/4f. With a reactive power of varying load 13 detected by a reactive power detector 14, an on-off control of SCR11 to 11' is operated by a controller 15, to control a number of banks of condensers 12, 12' required for varying reactive power.

Title: Exhaust gas purifying catalyst and its production thereof
Inventor: KONISHI KUNIHIKO
IPC: B01J23/64
Filed: 1994-02-04
Abstract: PURPOSE:To efficiently perform the removal of NOx and CO and the reduction of the outflow amt. of unreacted NH3 by a reduced use amt. of a catalyst by successively supporting a platinum component layer and a denitration catalyst component layer on a metal substrate. CONSTITUTION:This exhaust gas purifying catalyst 1 is obtained by successively supporting a platinum particle layer 3 and a denitration catalyst particle layer 4 on a metal substrate 2. NOx in exhaust gas comes into contact with the denitration catalyst particle layer 4 at first to react with NH3 to become N2 and H2. Since no platinum particle is present on the denitration catalyst particle layer 4, NH3 does not become NO by oxidation. Unreacted NH3 not reacted with NOx deffuses into the denitration catalyst particle layer and comes into contact with the platinum particle layer 3 to be oxidized to NO, which in turn comes into contact with denitration catalyst particles adjacent to platinum particles to react with residual NH3 to become N2 and H2O. CO in the exhaust gas has a property easily diffusable into the catalyst l and rapidly comes into contact with the platinum particle layer 3 and oxidized to CO2.
