Abstract: PURPOSE:To decrease the peeling of films, the delay in the phase at a high frequency and the output drop of the specific wavelength relating to the spacing length between shielding layer elements by providing plural discontinuous parts to one layer of a pair of layers having high magnetic permeability consisting of the shielding layers. CONSTITUTION:A shielding layer consisting of shielding patterns 32 corresponding to the sensing parts of MR elements 13 and finely segmented shielding patterns 32a is formed on a substrate 11, whereafter the MR elements 13 and connection parts 14 are formed via an insulation layer 10, and in succession, the other shielding layer 15 and protective layer 16 are used with an insulation layer 19 in-between, whereby magnetic heads are constituted. The magnetic flux patterns wherein the magnetized patterns recorded in a magnetic recording medium 40 are generated in the respective shielding layers in this case are plural parted magnetic flux patterns. Since the shielding layers are finely divided or are made discontinuous, stresses disperse, and the generation of the distortion in magnetism owing to the inclination of the films or stress in the stage of forming the elements is obviated; in addition, the responsiveness for a change in the magnetic field owing to a high frequency appears remarkably, and the phase characteristic in a high range is improved.

Title: Burner
Inventor: ADACHI IKURO
IPC: F23N1/02
Filed: 1986-05-14
Abstract: PURPOSE:To make it possible for the opening degree of a proportional control valve to rapidly respond to the quantity of combustion air supplied by carrying out a feedback control so that at least one of a proportional valve control circuit and a blower control circuit receives an output of a combustion sensor and an air-fuel ratio has a set value. CONSTITUTION:When a temperature adjusting volume 54 is manipulated, the output of a setting circuit 61 varies. A proportional valve control circuit 62 varies the quantity of power supplied in accordance with the variation in the output thereby to vary the opening degree of a proportional control valve 45. A blower control circuit 63 varies the quantity of power supplied in accordance therewith to vary the quantity of combustion air supplied of the blower 33. For this reason, a gas burns with flames constantly at a proper air-fuel ratio. Further, in a case where, by the variation of the component of gas supplied the gas does not burn with flames at a proper air fuel ratio, the blower control circuit 63 compensates for the quantity of supply of combustion air in accordance with the output of a thermocouple 52, and hence the gas constantly burns with flames at a proper air-fuel ratio.
