Inventor: HIGUCHI SHINSUKE
IPC: G11B21/21
Filed: 1994-09-20
Abstract: PURPOSE: To improve the durability of a protective film formed on the levitation face of a magnetic head slider used in a hard disk device. CONSTITUTION: A protective film formed on the levitation face of a magnetic head slider 2 is composed of two or more layers 6, 8, the hardness of the surface layer 8 is made higher than that of the underlayer 6 and the thickness of the surface layer 8 is made smaller than that of the underlayer 6. By this structure, contact load on the magnetic head slider by the fine surface protrusions of a magnetic disk is sustained by the elastic deforming force of the protective film over a wide range and the sinking of the protrusions by the plastic deformation of the protective film is not caused. As a result, the wear of the protective film due to digging by the protrusions of the magnetic disk is suppressed.

Title: Radio transmitter for car
Inventor: TANIGUCHI YOSHIYUKI
IPC: H04B1/08
Filed: 1983-11-29
Abstract: PURPOSE:To limit the transmissible distance of a radio signal to be transmitted within a short distance range and at the same time to secure the intensity of such a degree that ensures the assured transmission, by shifting the phases of the signals transmitted from a paired antennas with a 180 deg. phase difference between them. CONSTITUTION:When a request signal is received, a microcomputer 33 reads out the code signals proper to a car stored previously in a memory 34. The pulse train signal corresponding to the read proper code data is delivered to a modulation circuit 35. Therefore, it is possible to transmit the radio signals onto which the proper code signals are put through a loop antenna 31. Here the signal transmissible distance is further limited to improve more the resistance to wiretap. Thus a 180 deg. phase difference is secured by 180 deg. phase shifters 42 and 43 among request signals sent from paired loop antennas 41a and 41b as well as 41c and 41d. This attains a signal transmissible distance of about 1-2m from the paired loops.

Title: Self-oscillation suppressing method of electric- mechanical transducing element
Inventor: MURASE ATSUSHI
IPC: H04R23/00
Filed: 1982-12-21
Abstract: PURPOSE:To prevent satisfactorily the self-oscillations by impressing the trapezoidal wave driving voltage having the rise time equal to a period T or its integer-fold value of the 1st self-oscillation component of an electric-mechanical transducing element which is approximated by a secondary system of >=1 attenuation coefficient to said electric-mechanical transducing element. CONSTITUTION:A step-shaped waveform 23 shows an impressed voltage waveform of a bimorph 1 and also a displacement caused when the bimorph 1 answers faithfully the applied voltage. Therefore the waveform 23 shows the bimorph displacement amount corresponding to the impressed voltage. However the actual bimorph displacement produces selr-oscillations at a sudden displacement part like a waveform 24, and the period T of the bimorph displacement equals to the positive resonance frequency of the bimorph 1. The time from the rise part of the impressed voltage through the first peak value of the self-oscillation is set at T/2 for a transient answer of a secondary system of >=1 attenuation coefficient. Then the driving voltage having a rise time equal to the period T of the bimorph 1 is impressed like a trapezoidal wave pulse 34. Thus the bimorph 1 produces no self-oscillation.
