Title: Stress-removing intermediate layer of chip and board
Inventor: MICHAEL GUAN-TSON LEE
IPC: H01L21/60
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To bond a semiconductor chip through a flip-chip bonding method imposing a small stress on it by a method, wherein a flap-like region is demarcated between an upper contact pad and a lower contact pad that are mechanically isolated from a bulk intermediate layer, and the upper and the lower contact pad are displaced in the radial direction. SOLUTION: An intermediate layer 218 curves, expands or shrinks slightly between a chip contact 226 and a module contact 230 at high temperatures. A local distortion in a flap-like region allows a chip contact 226 to be displaced in the lateral direction from the module contact 230, so that thermal stresses imposed on a solder contact id reduced. A contact space 238 at a high temperature is narrower than a contact space 236 at a low temperature. With this setup, an intermediate layer structure that is of high reliability and through which a semiconductor chip can be bonded to a module in a flip-chip bonding method being less stressed can be obtained. Furthermore, the intermediate layer suitable for the manufacture of a dense ball grid array is obtained.

Title: Light emitting circuit
Inventor: IWATANI TOSHIO
IPC: H01L33/00
Filed: 1985-10-11
Abstract: PURPOSE:To facilitate stable constant light emission without being influenced by the fluctuatoni of temperature by connecting an optical semiconductor device to a light emitting diode in parallel. CONSTITUTION:A basic circuit of a light emitting circuit 10 is composed of a resistance 11 and a light emitting diode 12 which are connected in series and grounded. A parallel circuit 14, branched from the resistance 11, is composed of a phototransistor 13, which is an optical semiconductor devide. The light emitted from the light emitting diode 12 enters the phototransistor 13. Therefore, if temperature changes, the resistance 11 is also changed. When the resistance 11 becomes large, the current applied to the diode 12 is reduced so that the luminance entering the phototransistor 13 is also reduced and the collector potential of the transistor 13 is elevated. Therefore, the current applied to the light emitting diode 12 is increased and hence and luminance is increased accordingly and when the luminance of the original condition is recovered, the circuit is balanced and the light emission becomes stable. On the other hand, if the resistance 11 becomes small, the balanced condition can be obtained by the process opposite to the process as described above.

Title: Induction motor
Inventor: SAIMA TORU
IPC: H02K9/02
Filed: 1990-08-29
Abstract: PURPOSE:To prevent production of high frequency noise by setting the distance of a cooling air path, inclining from the outer circumferential face of stator coil to the proximity of frame, longer than half of the wavelength of a sound, produced through pulsation of air with a frequency determined by the product of the number of rotor bar and the number of revolution at the operating limit of motor, thereby suppressing sound wave amplifying effect. CONSTITUTION:A cooling air path comprising a plurality of sound wave guide boards 21 is formed at a point near the gap of a stator coil 4 through which pressure wave produced by the rotation of a rotor bar 11 passes. The pressure wave is fed in synchronization with the reciprocation of a sound wave produced from a pulsating air flow 15 which is produced by the fan effect of the rotor bar 11 between the outer circumferential face of the stator coil 4 and the inner circumferential face of a magnet frame 1. Amplification of noise due to the air flow is prevented by lengthening the reciprocal path of the sound wave between the stator coil 4 and the magnet frame 1, and the noise generation mechanism is broken by shifting the returning timing of reflected noise from the period of the pressure wave. According to the constitution, generation of noise can be prevented.

IPC: H01S5/00
Filed: 1986-09-26
Abstract: PURPOSE:To render a shape of a light permeation region more desirable and provide a manufacturing process having a high junction strength between a package and a transparent body by melting a glass tablet that is put on a formation region of an optical permeating aperture of a cap and fixing it to the cap so that no air leaks from the cap and also causing the light permeation region to turn into a parallel flat plate by forming the transparent body when it is still in a soft state. CONSTITUTION:After neading materials such as glass frit and binders and so on together, the materials are pressed in the form of disk by press to form a glass tablet 16 that has a diameter slightly smaller than the inside diameter of a cap 2. After placing the cap 2 on a flat table in a state of turning its cap the inside out, the tablet 16 is inserted in the cap and is molten by heating. The molten glass spreads all over the light permeating aperture 13 to have a relatively flat plane at upper and lower faces of a transparent body 14 that is still in a molten state. Subsequently, once ins treatment stops heating and starts curing, the periphery of the transparent body 14 adheres firmly to the edge part of the light permeating aperture 13 of the cap 2 so that no air leaks around the aperture. Furthermore, if a center part, that is the light permeating region where a laser light is permeable, is formed by a pair of forming dies 17 and 18, while the transparent body 14 does not cure and is in a soft state, such a region makes it possible to form a parallel flat plate part 15 where the surface and rear face are flat.
