Title: Thermal head
Inventor: SHIRAKAWA KYOJI
IPC: B41J2/335
Filed: 1996-01-11
Abstract: PURPOSE: To protect an adjacent feeder layer by breaking a partly glazed layer through a breaking protective layer formed at a position in close proximity to a common electrode layer for a feeder layer, and thereby, minimizing the generation of chippings. CONSTITUTION: When depositing a protecting layer 18 by sputtering on a thermal resistor layer 13, a feeder layer 14 and a breaking protective layer 15, a difference in the stacking density generates at the edge part of the breaking protective layer 15, and the mechanical strength of the part where such a difference occurs becomes low. Therefore, if a breaking line 19 is provided in close proximity to a common feeder layer 14a, a pitting which generates in the protective layer 18 by grinding is prevented from spreading farther by the edge part of the breaking protective layer 15. Thus the terminal surface of the common feeder layer 14a is no longer exposed. In addition, a partly glazed layer 12 tends to generate partly significant chippings by an impact at the time of grinding. However, the generation of chippings can be minimized by absorption of a grinding impact by the metal layer, if the breaking protective layer 15 is formed in the same type of metal as the feeder layer 14 and the partly glazed layer 12 is ground through the metal.

IPC: G11B5/31
Filed: 1989-02-01
Abstract: PURPOSE:To prevent the lowering of a magnetic permeability when a large anisotropic stress is applied on a magnetic core and the deterioration in the electromagnetic conversion characteristics of the magnetic head by forming an upper magnetic film and a lower magnetic film to a circular shape. CONSTITUTION:This magnetic head consists of the lower magnetic film 2 formed on an Al2O3 film 12 of a substrate 1 and the upper magnetic film 3 which is formed on the lower magnetic film 2 in such a manner as to bring one end 31 into contact with one end 21 of the lower magnetic film 2 and to dispose the other end 32 to face the other end of the lower magnetic film 22 via a magnetic gap G and constitutes a magnetic circuit having a magnetic gap S in a part together with the lower magnetic film 2. The stress acting on the films is determined by the shape of the magnetic core and since the region in the front end part of the core is sensitive to recording and reproducing characteristics, the lower and upper magnetic materials 2, 3 are formed to the circular shape so as to relieve the stress in the front end part of the core. The magnetic anisotropy of the upper magnetic film 3 and the lower magnetic film 2 of the thin-film magnetic head is diminished in this way and the stable electromagnetic conversion characteristics which obviates the generation of the reproducing waveform distortions are obtd.

Title: Adaptive controlling device
Inventor: YOSHIDA TOSHIO
IPC: B23Q15/14
Filed: 1980-02-21
Abstract: PURPOSE: To safely switch over from a noncontact state to a contact state by counting the contact and noncontact states by means of a reversible counter device when the condition in which a tool and a to-be-worked piece are not contacted with each other during the machining applied in a machine tool appears to cause a waste of machining time.  
     CONSTITUTION: When a condition change detecting device 20 receives an output signal of a condition detecting device 14 and identifies that the tool and the worked piece are changed over from the contact state to the noncontact state, the output of the device 20 causes a flip-flop 26 to be set and informs a numerical value controlling device of requirement for a high speed through a filter device 34. In the noncontact state, and AND gate 16 opens and migration pulses P fed out of a control signal supplying device 22 are counted up by the reversible counter device 30. When an inversion identifying device 24 identifies the inversions of the tool and the work piece in the directions of the relative movements, a switch changing over device 28 is changed over. As a result, the high-speed feed is continued until the content of the reversible counter device 30 is reduced to 0.
