Inventor: OKITSU TOSHIHIRO
IPC: F42D5/02
Filed: 1994-08-15
Abstract: PURPOSE: To easily and effectively know the presence or the absence of unexploded residual explosive powder by previously inserting the end of a residual explosive powder searcher made of a high tensile strength wire into an explosive powder or non-explosive powder composition, drawing, after the end of burning operation, the searcher, and examining the state change such as the burning, discoloring, etc., of the end of the searcher. CONSTITUTION: The end of a residual explosive powder searcher 8 made of a high tensile strength wire is inserted to the rear of a cartridge 3. High tensile fiber, metal wire, etc., can be used as the tensile strength wire. When burning operation is conducted, igniter 6 is fired, high temperature and high speed reactive composition 5 in the cartridge 3 is reacted, and fragile material 1 is cracked. Then, residual explosive powder searcher 8 is drawn. Whether the state change such as burning, discoloring, etc., is present or not at the end of the searcher 8 is visually observed. When there is no change, the composition 5 is not burned, and the presence of the composition 5 can be judged at the crushed position.

Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To improve the thermal fatigue life of solder bumps, by suppressing the influence of the thermal strain caused by the difference between the coefficients of linear expansion of a semiconductor chip and a wiring board. SOLUTION: The coefficient of linear expansion of an interposer 2 is adjusted to nearly that of a printed wiring board 5 and, at the same time, the thickness of the interposer 2 is adjusted to >=400 μm. When the coefficient of linear expansion of the interposer 2 is made nearly equal to that of the wiring board 5, the thermal strain between the interposer 2 and wiring board 5 can be reduced. In addition, when the thickness of the interposer 2 is adjusted to >=400 μm, the transmission of the displacement a semiconductor chip 1 to solder bumps 4 can be prevented. When a CSP 10 is mounted on the wiring board 5, the thermal fatigue lie of the solder bumps 4 can be improved, because the influence of the thermal strain caused by the difference between the coefficients of linear expansion of the IC chip 1 and wiring board 5 can be suppressed.

Title: Method for reproducing magneto-optic recording medium and magneto-optic recording medium
Inventor: HIROKANE JUNJI
IPC: G11B11/10
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To increase a resolution when a magneto-optic recording medium is recorded, reproduced with a small diameter and a small distance of recording bits, by heating a reproduction layer to not lower than a near Curie temperature by beam spots, and forming a front and a rear masks to the reproduction layer below the spots. SOLUTION: A Curie temperature of a reproduction layer 1 is set to be lower than in a conventional example. A third temperature area 102 is formed in a beam spot. In the area 102, the reproduction layer 1 is not lower than the Curie temperature or in a temperature range considerably close to the Curie temperature, and therefore, the reproduction layer 1 is never magnetized at all or minimally magnetized. A reproduction signal generated at the areas 102 is accordingly zero or minimum. In other words, the area 102 forms a rear mask, so that the medium is reproduced with super resolution owing to the double mask of the rear mask and a front mask at an in-plane magnetization of a first temperature area 101.  At this time, while magnetic domains 103, 104 of the reproduction layer 1 are turned to a perpendicular magnetization state, only the magnetic domain 103 within a range of the beam spot 100 is reproduced and sufficient reproduction signals are obtained. Magnetic reproduction with super high resolution is hence realized.
