Title: Structure for mounting semiconductor chip
Inventor: TANAKA HIROKAZU
IPC: H01L23/373
Filed: 1992-11-17
Abstract: PURPOSE:To prevent the interface of a bonding layer from being cracked or stripped due to thermal fatigue by a method wherein a heat-dissipating material is formed of aluminum whose purity is specific. CONSTITUTION:A conductor substrate 12 for circuit formation use is bonded to the surface of an insulating substrate 11. An aluminum heat sink 13 is fixed and bonded to the surface of the conductor substrate 12 by a solder 14. A plated layer 15 which makes wettability to the solder 14 good is applied to the surface of the aluminum heat sink 13. A silicon chip 16 is mounted on the surface of the aluminum heat sink 13 so as to be fixed and bonded by a solder 17. In this case, aluminum whose purity is 99.9% or higher is used for the heat sink 13. In addition, the thickness of the heat sink 13 is set at 0.2mm or higher. In such a structure, the deformation resistance of a heat-dissipating material is small, and the material is plastic-deformed easily. As a result, the relaxation effect of a thermal stress generated inside a solder layer bonding the silicon chip can be increased.

Filed: 1988-12-27
Abstract: PURPOSE:To obtain a wall mount antenna able to cope with lain snow and capable of tilting its beam by moving a distributer corresponding to the same beam tilt variable direction in the same direction in interlocking with an operation knob. CONSTITUTION:A circularly polarized wave from a satellite reaches radiation elements 4L, 4R having a degeneration separation part 11 and a converted linearly polarized wave is sent to a transmission line 10 via a coupling hole 5. After each polarized wave is mixed by a matching section 6 of an elevating angle adjustment section 2 and a distributer section, the polarized wave is mixed with a polarized wave from other matching section at a matching section 8 of an azimuth angle adjustment section 8 and a distribution section 9. The matching section 6 and the distribution section 7 are moved in a direction (b) and the matching section 8 and the distribution section 9 are moved in a direction (c) along with the length of the transmission line 10 by an external knob together. The elevating angle adjustment section 2 and the azimuth angle adjustment section 3 are moved to the radiation element section 1 to make the phase of the linearly polarized wave led or lag independently corresponding to the directions b,c respectively. The space of the transmission line acts like a waveguide and the radiation elements are connected in parallel. Through the constitution above, the antenna mounted perpendicularly to the wall face of a building, coping with lain snow and whose beam is tilted is obtained.

Abstract: PURPOSE: To stably and excellently carry a transfer material by constituting the guide surface of a guide member guiding the leading edge part of the transfer material so that the central part thereof is low and it is gradually higher as it goes to both ends. CONSTITUTION: The guide surface 6a of the exit-side upper guide 6 of a fixing device 100 on which the leading edge of the transfer material is rubbed and guided is formed so that the central part thereof is swollen to a carrying path 8 side by viewing from the width direction of the transfer material S which is carried. Then, the path 8 is formed so that the central part is narrow and it becomes wider as it goes to both end parts. The central part of the material S fed out from a fixing roller pair 9 is separated early and it enters the guide surface 6a in a curved state. Since the shape of the leading edge of the material S is almost aligned with the shape of the entrance part of the path 8, the abutting pressure of the material S on the guide surface 6a is uniformly dispersed extending over the whole width of the material S.  Therefore, such a situation that toner after fixing operation is executed is taken off or jam occurs because the taken-off toner is solidified and the following material S is obstructed to be carried is evaded.

Title: Production of liquid crystal display device
Inventor: KURAMOCHI OSAMU
IPC: G02F1/1339
Filed: 1990-11-29
Abstract: PURPOSE:To greatly improve the accuracy of a spacing and to obtain the liquid crystal display device having a good display grade by changing the pressure for sealing both substrates to each other at the time of curing a sealing agent to seal the counter substrates. CONSTITUTION:Transparent conductive electrodes 3, 4 consisting of, for example, ITO and oriented layers 5, 6 are formed on one main surface 1a, 2a sides of the 1st and 2nd substrates 1, 2. The 1st and 2nd substrates 1, 2 are then sealed at the circumference by the sealing agent 7 in such a manner that the one main surface 1a, 2a sides thereof face each other. The reaction of a hardener is accelerated and the viscosity lowers when the temp. of the sealing agent 7 attains a certain temp. The viscosity rises sharply and the sealing agent begins to harden when the agent is further heated. The pressurizing force is, thereupon, increased from the temp. at which the viscosity begins to decrease. The increase of the pressurizing force is stopped before the attainment of the temp. at which the viscosity begins to increase sharply. This change is controlled to 200 to 700g/cm<2> by which the accuracy of the inter-substrate spacing is greatly improved.
