Patent JP-H11284096-A (JP)
Title: Semiconductor package
Inventor: TAKEYA NORIAKI
IPC: H01L23/12
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To improve the reliability against the thermal influence such as heat cycle, by adhering semiconductor elements to a flexible substrate through an elastic adhesive layer for absorbing the thermal expansion difference between both, and providing through-holes through the flexible substrate for absorbing the pressure rise due to heating of moisture contained in the flexible substrate. SOLUTION: An elastic adhesive layer 4 is made of a porous polytetrafluoroethylene so as to absorb the thermal expansion difference based on the thermal expansion coefficient difference between a flexible substrate 1 and semiconductor element 5, the flexible substrate 1 has through-holes 9 at the center thereof, i.e., just beneath the semiconductor element 5 and hence can escape to outside the pressure in a semiconductor package, rapidly rising due to the thermal expansion of moisture contained in the flexible substrate 1 during solder reflowing, etc., thereby avoiding breaking the semiconductor package or cracking the semiconductor element. Thus it is possible to improve the reliability against the thermal influence such as heat cycle.

Title: Toner concentration detection device and developing device
Inventor: FUMA HIROSHI
IPC: G03G15/08
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To improve detection accuracy and attain highly reliable detection by setting a toner concentration detection device movable relative to a developer storage layer. SOLUTION: A toner concentration detection device 20 is set so as to come in contact with the screw of a developer transport member 16(17) and be movable. A substrate 20a has a shape following the shape of the cross-section of the developer transport member 16(17). Between developer D transported by a screw and a detecting circuit 20b, developer caused to deviate from the transport cross-section of the screw and remaining untransported, that is, developer which is not reflected in the result of toner consumption is small and fixed in amount, and the factors of noise in the detection of the toner concentration of the carried developer D are scarcely existent. The result of the detection of the developer D transported by the rotation of the developer transport member 16(17) fluctuates. However, by finding a highest value, the lowest value, or an average value, toner concentration can be detected with very high accuracy.

Title: Method and apparatus for producing magnetic recording medium
Inventor: MITANI TSUTOMU
IPC: C23C16/27
Filed: 1986-04-11
Abstract: PURPOSE:To form a protective film at a high film forming speed without generating wrinkles, etc., by accelerating the ions in plasma contg. an element to constitute the protective film by Coulomb force and irradiating the ions on a magnetic recording medium. CONSTITUTION:The inside of a vacuum vessel 1 in which the metallic magnetic recording medium 8 is set is evacuated and thereafter, gaseous methane and gaseous argon 4 are introduced into a plasma pipe 6 and are converted to plasma by a high-frequency power source 2 and an excitation coil 3. The magnetic layer side of the medium 8 is connected by an intermediate roller 10 to the low potential side of a DC power source 9. The ions in the plasma are accelerated by Coulomb force toward the medium 8 when the DC voltage grounding the high potential side of a power source 9 and a meshed electrode 5 is impressed. The accelerated ions irradiate the medium 8. The heat of the medium 8 by the irradiation of a large quantity of the ions is quickly dissipated to a revolving roller 11 by the grounding of the roller 11 at the same instant. The protective film of a diamond-like carbon film is thus satisfactorily formed without generating the wrinkles.
