Title: Method for controlling positioning of magnetic head
Inventor: NAKAI KENICHI
IPC: G11B5/55
Filed: 1982-06-04
Abstract: PURPOSE:To use the whole magnetic disc for data writing, by repeating positional correction by comparing a analytical values in frequency of signals read out from a track in a data available area. CONSTITUTION:When a motor 28 is driven and a disc 30 is rotated, a positioning command is outputted from a device controlling means 10 to a magnetic head 20. A signal read out from the magnetic head 20 is applied to a frequency analyzer 42 through a voltage amplifier 38 and the effective data value 150 is fed back to a moving distance controlling part 16. The moving distance controlling part 16 calculates the deviation between the track position indicated by the fed back effective data value 150 and an objective track position and applies an output corresponding to the deviation to a power amplifier 18 to move the magnetic head 20. By repeating said operation, the magnetic head 20 is positioned on the objective track corresponding to the command of the device controlling means 10.

Title: Superconductor transmisson line
Inventor: UIRIAMU JIYOSEFU GIYARAGAA
IPC: H01B12/10
Filed: 1991-04-02
Abstract: PURPOSE: To improve an AC value without generating hysteresis by containing a plurality of conductive elements that have an anisotropic magnetic parameter and a crystal structure around a base. CONSTITUTION: Conductive elements 38, 40 are superconductor, whose crystallographic basal plane 44 are in parallel with an insulation board 42. A current that flows in parallel with an axis 46 in a power transmission line block 26 induces a magnetic field 48 that is oriented toward a surface that is vertical to the axis 46. The magnetic field 48 surrounds a current route such as an electric current route inside an element 40. Lines of the magnetic field 48 intersects substantially vertically the plane 44 in the elements 38. A magnetic field that intersects practically vertical the plain 44 is induced by a current that flows through the elements 38. For example, in a constitution of a power transmission wire 20, leads 30, 32 can be connected with a bar 50 that is secured to edges of the elements 38, 40 extending through the plane 44.  Therefore, an AC value can be maximized without generating hysteresis by maximizing a critical magnetic field value in a lower part of an applied magnetic field to maximize its linear area.

Title: Hot water supply apparatus
Inventor: UESUGI YOSHIKO
IPC: F24H1/10
Filed: 1989-04-14
Abstract: PURPOSE:To decrease the overshooting of hot water temperature at the time of starting the burning when the load is low by causing the PID computation to be carried out after once clearing the burning rate for the previous hot water discharge if the load, i.e., the required calorific value to bring the hot water temperature up to the set temperature is low, and causing the PID computation to be carried out with the previous burning rate retained if the load is high. CONSTITUTION:The level of load computed by the FF computation is determined by a sequence control means 9c, and, if the load is determined to be low, the result of the PID computation formula Tc = Kc . (TER + Ti . SIGMATER + Td . DELTATER), where TER is the deviation, Kc the proportional constant, Ti the integration constant, and Td the differential constant, i.e., the value of the integration term employed at the time of the burning control from the previous PID control is retained in a memory means 9d. When beginning the PID computation the PID computation means 9a, the PID computation is carried out without applying the value of the previous integration term to the formula, and, based on the computed load level, the opening of the proportioning valve 5 is controlled by the sequence control means 9c to regulate the burning rate at the burning section 2. On the other hand, if the load is great, the previous PID computation result is not cleared but is applied to the formula as is to begin the PID computation for burning control.
