Title: Multitrack magnetic head
Inventor: TORIO JIROU
IPC: G11B5/187
Filed: 1981-06-03
Abstract: PURPOSE:To reduce the influence of a lift and dust upon a magnetic tape surface, and to improve short wavelength characteristics, by forming space parts, opened on a medium opposed side, at medium opposed parts between respective medium opposed surface of a head core. CONSTITUTION:A head 15 has spaces 16a-16e at medium opposed parts. Consequently, the surface of a magnetic tape 10 is curved in a saddle shape which is projected at cores 2a-2d and recessed at the space parts 16a-16e between guard cores 3a and 3d, and cores 2a and 2d. Since the head 15 comes into contact with the magnetic tape only on the medium opposed surfaces of the cores 2a-2d, an air flow along the surface of the tape 10 during high-speed running increases in coefficient of lateral leakage, reducing the spacing between the tape 10 and head 15. Further, the rate where dust enters between the head 15 and tape 10 is decreased greatly by the space parts 16a-16e.

Title: Rotational frequency detector for squirrel-cage induction motor
Inventor: YANAGIUCHI YOSHIHIKO
IPC: H02K11/00
Filed: 1979-07-10
Abstract: PURPOSE:To detect rotational frequency at a low cost, by using a magnetic current converter such as a search coil or a Hall element to detect magnetic flux due to a current flowing through the end ring of a rotor. CONSTITUTION:Since a secondary current flows in a rotor bar 1 and is short-circuited by an end ring 2, the direction of the current in the end ring is vertical. Magnetic flux due to the current in the end ring extends as shown by dotted lines 5 in the figure. A magnetic current converter 6 such as a search coil or a Hall element is placed perpendicularly to the magnetic flux 5. The current flowing in the end ring varies depending on rotational frequency and the magnetic flux 5 varies depending on the current. As a result, a voltage induced across the output terminals 7, 8 of the converter 6 changes depending on the rotation of a rotor so that the rotational frequency of an electric motor can be detected. The rotational frequency dependent on the powr supplied state and loaded state of the motor can be detected from the output signal across the terminals 7, 8.
