Title: Hybrid integrated circuit
Inventor: MURAKAMI SHIGENOBU
IPC: H01L25/00
Filed: 1984-04-20
Abstract: PURPOSE:To make it possible to prevent the flowing out of a bonding agent to the side of a power transistor chip, even though the power transistor chip and the substrate of a hybrid IC for a control circuit are arranged in the close proximity, by providing a slant part on a metal base part, which fixes the control circuit, so that the power transistor side becomes high and the side of the peripheral part of the metal base becomes low. CONSTITUTION:A slant part is provided at a base part 1b, to which an insulating substrate 8 of a hybrid IC is attached, in a metal base 1, by embossing. A step 1c is provided between the part 1b and a base part 1a, to which a power transistor chip 2 is attached. The slant part is provided in the direction opposite to the position of the power transistor chip 2. When the insulating substrate 8 is fixed to the base part 1b by a bonding agent 9, the bonding agent 9 flows in the opposite direction with respect to an alumina substrate 4. But the bonding agent does not flow to the side of the alumina substrate 4. Therefore, the bonding agent 9 does not fill a part between the power transistor chip 2 and the hybrid IC substrate 8. When a silicon gell 19 is filled, air does not remain in a bump space since a bump flip chip 7 is attached in a slanted state.

Title: Rotary transformer
Inventor: INOUE HIROTO
IPC: G11B5/02
Filed: 1987-04-02
Abstract: PURPOSE:To reduce crosstalk through reduction of a current value produced by the effect of electric field among the currents produced in a coil not related to the inherent signal transmission, by providing a short-circuitted short ring between coils and electrically grounding the short ring. CONSTITUTION:Since magnetic flux passing through a magnetic path C4 is reduced by an eddy current effect of short ring 8, a current I4 produced by the effect of magnetic field can be lowered by the short ring 8. Meanwhile, potential is distributed in the peripheral field due to the surface voltage of S coil 5b which is an input source but since the short ring 8 is grounded through a winding pin 10, potential at the area near the R coil 6a becomes small. There fore, a current I5 produced by the effect of electric field can also be lowered in comparison with that in the case where the short ring is not grounded. There by, intensity of electric field at the region near the coil not related to the inher ent signal transmission can be lowered, a current produced by the effect of electric field can be lowered than that obtained when the short ring 8 is not grounded and crosstalk can be reduced.
