Title: Access servo mechanism for magnetic disc unit
Inventor: OTSUKI HARUAKI
IPC: G11B21/10
Filed: 1991-12-20
Abstract: PURPOSE:To obtain a high response access servo mechanism by coordinating double action means having high and low responses and long and short strokes. CONSTITUTION:When a current head position is shifted, control systems for driving means G1(S), G2(S) calculate operating amounts according to respective control operations and deliver signals, respectively, to corresponding driving means. Consequently, respective driving means begin operation for correcting positional shift. At that time, means G1(S) responds slower than means G2(S) and at a point of time when the control difference of means G1(S) goes '0', displacement amount Y1 is large but Y2 is small. Means G2(S) is operated in the direction to decrease the displacement Y1 continuously even under a state where the control difference of G1(S) went to '0'. Consequently, means G1(S) also operates to decrease the displacement Y1 while keeping a head on the center of a target track and the entire servo system enters into steady state when a neutral position is reached.

Title: Exhaust gas cleaner for engine
Inventor: NIIZAWA MOTOHIRO
IPC: F01N3/02
Filed: 1989-12-27
Abstract: PURPOSE:To perform stabilized regeneration by judging the finish of regeneration from the integrated value of reduction in particulate amount grasped by dividing into recombustion process amount and trapped amount. CONSTITUTION:A control unit 41 calculates the recombustion process amounts per unit time for each divided operation range according to the values detected with an outlet temperature sensor 33 and trapped particulate amount per unit time. The amount obtained by subtracting the trapped amount from the recombustion process amount is assumed to be the amount of reduction and integrated for every unit time. Whether the regeneration of a trap 3 is finished or not is determined by comparing the integrated value with a predetermined reference value. Since the reduction in the particulate amount is grasped separately for the recombustion process amount and the trapped amount, those amounts are known accurately, even if operating condition and exhaust temperature condition vary, according to the variation. Since the total amount of reduction is obtained by integration those amounts are obtained accurately according to the transient changes and exhaust gas temperature changes.

Filed: 1989-12-27
Abstract: PURPOSE:To find the transformation behavior in solidification phase with respect to a cooling speed and to prevent transformation cracking by applying a magnetic field on a cast product immediately after solidification, cooling the product at a constant speed, continuously measuring electromagnetically induced electromotive force, and detecting the change in permeability. CONSTITUTION:A molten metal sample 1 is inputted into a container 2, cooled at a preset cooling speed utilizing a heater 5 and solidified. Then, a specified AC magnetic field is applied on the sample 1 with a magnetizing coil 3 and further cooled. When the temperature of the sample becomes about 900 deg.C, the electromagnetically induced electromotive force which is generated in a magnetism detecting coil 4 is continuously recorded in a recorder 7. When the sample 1 is cooled, and the solidified phase is formed, at first austenite which is gamma iron appears. When the temperature is further decreased, the phase is shifted from the gamma iron to alpha iron. Since the alpha iron is a ferromagnetic material, the alpha iron is magnetized in the magnetic field formed by the magnetizing coil 3. Thus, induced electromotive force is generated in the magnetism detecting coil 4, and a current flows. Three transformations such as pearlite sequentially appear in the alpha iron. The cast product having the intended physical properties can be obtained from the diagram the correlation between the transformation point and the cooling speed.
