Title: Magneto-resistance effect element
Inventor: KITADA MASAHIRO
IPC: H01L43/08
Filed: 1982-07-21
Abstract: PURPOSE:To reduce the gap length and at the same time to vary the thickness of a conductor film for current bias regardless of the gap length, by providing a current bias film on a substrate equal to a ''Permalloy'' sensor film with adjacency to and no overlap with the ''Permalloy'' film. CONSTITUTION:A ''Permalloy'' sensor 4 has a 20X50mum size with 40nm thickness, and an Al current bias conductor 5 of 400nm thickness with 20mum width is formed on a substrate in parallel to the ''Permalloy'' film. In this case, the bias magnetic field characteristics are obtained as shown in the figure when Al is energized by 10<6>A/cm<2>. The intensity of the bias magnetic field differs by the form and composition of the used magneto-resistance effect film such as the ''Permalloy'' film, etc. and will usually suffice with 10-30 Oe. As a result, a sufficient bias magnetic field is ensured with not having overlap between the ''Permalloy'' sensor film and a conductor film for current bias and by selecting the distance between both films at the optimum value. Thus the gap length is limited with an electric insulated film regardless of the form of the current bias conductor. This element reduced the gap length.

Filed: 1991-05-30
Abstract: PURPOSE:To reduce the degree of observing a joint by executing the joint between signals with strong correlation when time division multiplexing both side signals. CONSTITUTION:The center part of a wide aspect signal is extended to a current aspect by a horizontal extender. On the other hand, time extension is executed to the side part as well by the horizontal extender. These signals are rearranged into a format shown in multiplexing side information by a rearranger. The side information is multiplexed and transmitted by a main panel signal. On the reception side, the information is separated into the main panel signal and a side signal and afterwards, time compression into the area of the center part is executed to the main panel signal. The side signal is rearranged by the rearranger and fitted into the area of the side part after time compression by a horizontal compressor. The both signals, to which time compression is executed, are added by an adder, so as to reproduce a wide aspect signal. Thus, since the joint is positioned at the signal with strong correlation, there is no signal disturbance caused by the joint.
