Title: Thin film magnetic head
Inventor: WATANABE TAKAAKI
IPC: G11B5/187
Filed: 1986-06-04
Abstract: PURPOSE:To eliminate undershoot to eliminate waveform defects and the degradation in resolution by forming edges of magnetic poles, which form a recording and reproducing gap, and the other edges of magnetic poles nonparallel with each other. CONSTITUTION:A thin film magnetic head 1 consists of two upper and lower magnetic poles 11 and 12 and a recording and reproducing gap 13 interposed between magnetic poles 11 and 12. Edges 14 and 15 of magnetic poles which form the recording and reproducing gap 13 are made nonparallel with the other edges. Since edges 14 and 15 are nonparallel with edges 16 and 17, the effect that magnetic poles 11 and 12 are infinitely extended equivalently in comparison with the length of the gap 13 is attained, and undershoot does not occur and the recording density characteristic is made flat.

Title: Transmitter of information for moble body
Inventor: KITAGAKI TOORU
IPC: H04B5/00
Filed: 1983-07-18
Abstract: PURPOSE:To eliminate the interference of a radio wave near an LCX boundary by comparing reception electric field levels of each LCX (leakage coaxial cable), selecting only a sole LCX section and transmitting a radio wave from the said LCX section only. CONSTITUTION:Although a reception electric field of an LCX12 is unstable when a mobile body 101 moves and a front on-vehicle antenna 3 approaches an end of the LCX12, since the antenna 3 is placed at the inside position more closer than the end of the LCX13, the LCX13 obtains a stable reception electric field. A switching signal is given to a logical circuit 61 by detecting facts that the reception electric field level of the LCX12 is a prescribed value or below and also a reception level of an LCX13 is a prescribed level or over. The logical circuit 61 gives a radio output stop command to a radio output circuit 42 and a radio output transmission indication to a radio output control circuit 43 by using this switching signal. Thus, the transmission of permission speed information corresponding to the position of the mobile body 101 is performed by the LCX13 only.
