Title: Yoke type film magnetic head
Inventor: SHIIBA KENGO
IPC: G11B5/39
Filed: 1986-10-09
Abstract: PURPOSE:To prevent generation of Barkhausen noise by inclining the axis of easy magnetization in a magneto-resistance effect element at a specific angle with the longitudinal direction of the magneto-resistance effect element. CONSTITUTION:The direction of the axis of easy magnetization in the magneto- resistance effect element (MR element) 2 of a yoke type thin film magnetic head is inclined 10 deg. clockwise with the longitudinal direction of the MR element. A weak magnetic field in an arrow   mark direction is, therefore, impressed by ferromagnetic films 3, 3 to the MR element 2. An angle dispersion is generated in the direction of the axis of easy magnetization thereof. Supposing that the angle dispersion is about + or -10 deg., the angle dispersion is distributed in a 0-20 deg. range with the longitudinal direction of the MR element in the entire region thereof. The generation point of discontinuous peak can thus be moved to either positive or negative side in the magnetic field Ha corresponding to a signal magnetic field and the magnetization switching is preventable if the operation point verging on the side having the discontinuous leaps is moved. The generation of the Barkhousen noise is thereby averted.

Filed: 1988-09-27
Abstract: PURPOSE:To enhance utilization ratio of base paper and obtain a friction material without orienting properties of fibers by punching an annular cardboard formed by using a sheet forming mold having an annular sheet forming part having dimensions close to those of a product into an annular shape of prescribed dimensions. CONSTITUTION:A dispersion is formed into a sheet of paper in a sheet forming mold 1 having an annular sheet forming part 7 having dimensions close to those of a product so as to nearly perpendicularly pass the dispersion through a net 5 of the sheet forming mold. The resultant base paper is then punched to produce the product. In the process, the amount of useless parts formed in the base paper is extremely reduced and a molded product having a good dimensional accuracy is obtained without increasing the production man-hour.

Title: Method for measuring tire noise
Inventor: YAMASHITA BUNICHI
IPC: G01H3/00
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To provide a method by which the slipping sound produced between a tire and a road surface can be measured. SOLUTION: In a method for measuring tire noise, tires 2R and 2L having different dynamic load radii r1 and r2 are supported on tire rotating shafts TC which are rotated at the same rotating speed and simultaneously brought into contact cylindrical drums 5 fixed on a drum rotating shaft DC which is set in parallel with the shafts TC and has a radius R. Then the shafts TC or the shaft DC is rotationally driven while the tires 2R and 2L are held in a state where their positions are restricted in the running directions and, at the same time, the slip ratio S which is the ratio sk(r1-r2)/(rl+r2)| of the difference between the dynamic load radii r1 and r2 of the tires 2R and 2L to the sum (r1+r2) of the radii r1 and r2 is set at >=0.05 and <=0.20.  Therefore, slips can be caused between the tires 2L and 2R and drums 5 and the slipping sounds between the tires 2R and 2L and drums 5 can be measured.

Abstract: PURPOSE:To constitute a device so that the direction of a magnetic resonance image is not limited, and also, to prevent the deterioration of S/N, and to enhance the reliability by using a non-ground circuit using a radiation wave induction element as the switching circuit of a reception circuit. CONSTITUTION:The device has a reception circuit K11 for receiving an MR signal in a resonance state, and a switching circuit K12 for switching the resonance state of the circuit to a non-resonance state, the switching circuit has a photodiode D12 being a radiation wave induction element, and executes a decoupling operation of an active type of the receiving circuit, and as for the photodiode, since a driving power source is unnecessary, or its is insulated from the power source, the ground is eliminated. In this state, in the case the MR signal is not received, the radiation wave induction element of the switching circuit, is irradiated with the radiation wave and by bringing the switching circuit to resonance, the receiving circuit becomes a non-resonance state. In the case of receiving the MR signal, by stopping the irradiation of the radiation wave to the radiation wave induction element, the reception circuit becomes a resonance state. Since the switching circuit is non-ground, in the case of receiving the MR signal, the leakage of a reception signal is prevented, the deterioration of S/N can be prevented, and also, the direction of a magnetic resonance image is not limited.
