Inventor: MIZUSHIMA KOICHI
IPC: G01B21/30
Filed: 1992-09-14
Abstract: PURPOSE:To restrict the direction of the spin magnetism efficiency to a specific direction by forming the tip of a probe in a laminate structure consisting of a conductive ferromagnetic substance and a dielectric anti-ferromagnetic substance. CONSTITUTION:A conductive ferromagnetic substance 1 consisting of spinel type ferrite Fe3O4 and a dielectric anti-ferromagnetic substance 2 consisting of CoO are laminated in layers to constitute a probe. Between the two substance members 1, 2, an interchange action acts while pinching their interface. The spin direction of the anti-ferromagnetic substance 2 is fixed to the crystal axis, not changeable with external magnetic field. If ferromagnetic substance 1 is used solely, its spin direction can not be restricted unless an external magnetic field is impressed, but here the orientation is put in alignment with the direction of the surface spin of the anti-ferromagnetic substance 2. That is, adjoining anti-ferromagnetic substance 2 plays the role of an external magnetic field.

Title: Semiconductor package
Inventor: ISHIZUKA MASARU
IPC: H01L23/34
Filed: 1987-09-29
Abstract: PURPOSE:To preferably cool generated heat at the normal time even if a thermal load is temporarily increased by sealing wax in a sealed space formed between a cap and a substrate, and further connecting fins between the cap and the substrate. CONSTITUTION:The face of a substrate 2, disposed at opposite side to the face for placing a semiconductor IC chip 1 is thermally connected to a cap 3 with fins 11. With such a configuration, when the chip 1 generates heat, the heat is transferred to the substrate 2. The heat transferred to the substrate 2 is transmitted at one side to the mixture 4 of wax and powder metal, and at the other to the cap 3 through the fins 11. In this case, when the quantity of the generated heat of the chip 1 is abruptly increased, the wax is melted by the heat at that time, the heat is absorbed by the phase change, thereby maintaining the temperature constant. On the other hand, if the generated heat is of the degree not melting the wax, it is transferred to the cap 3 by thermal conduction of the fins 11 and the metal powder, and dissipated through the cap 3.

Abstract: PURPOSE:To make application to versatile processes possible by making a selection between functions for holding or not holding an input measurement from a sensor at a value prevailing immediately before occurrence of a failure in the sensor at the time of occurrence of the failure in the sensor. CONSTITUTION:In a function selecting section 6a, switches 71, 72 are interlocked, respectively, with switches 12a, 31a of input switching function 12 and output switching function 31 and the functions 12, 31 are actuated when a sensor failure detecting function 11 detects abrupt change of an input signal to produce a sensor failure signal.
