Title: Method for removing solder ball
Inventor: ISHIKAWA TAKATOSHI
IPC: H05K3/22
Filed: 1992-11-27
Abstract: PURPOSE:To simply and surely remove solder balls produced on printed board by allowing solder balls to be contained in a synthetic resin film formed on the surface of the printed board and separating the synthetic resin film from the printed board. CONSTITUTION:A lead 3 is soldered to the electrode 5 of a circuit pattern in the surface of a printed board 4 by solder but a part of molten solder 6 flows to the periphery to produce solder balls 7. Then, a synthetic resin film 8 is formed in the surface of the printed board 4 to allow the solder ball 7 to be contained in the synthetic resin film 8. The synthetic resin film 8 is formed by applying liquid-like synthetic resin and then curing it. Next, when the synthetic resin film 8 is separated from the printed board 4, the solder balls 7 are removed together with the synthetic resin film 8. Thereby, even a solder ball produced in narrow place can be simply removed.

Title: Plasma address liquid crystal panel
Inventor: HINCHLIFFE ROBERT D
IPC: G02F1/1333
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To improve non-unifomity in electric charge distribution and electric field distribution by keeping an interval practically longer than a specified length between an electrode and a cover sheet. SOLUTION: This panel is provided with a channel member 4 provided with plural channels 20 respectively having two electrodes 24 and 26 and a cover sheet 6 for covering these plural channels 20, and the electrodes 24 and 26 keep the interval practically longer than 10 μm with the cover sheet 6. For example, the distance between the electrodes 24 and 26 and the downside surface of the cover sheet 6 is at least about 15 μm. This distance is enough for a high electric charge density near the electrodes 24 and 26 not to considerably affect the electric charge distribution on the lower side face of the cover sheet 6. Therefore, the electric charge distribution on the lower side face of the cover sheet 6 is made much more uniform rather than the case of making the electrodes 24 and 26 proximate to the cover sheet 6.  Therefore, a voltage crossing the volume element of an electro-optical material layer 10 is made much more uniform.

Since the box 2 is made up of a high conductive metal such as aluminum or copper, the heat from a heater 3 is quickly transferred to all parts of the box 2, so that the box 2 is brought into a heated condition of a uniform temperature distribution. In this case, since a far-infrared-radiation radiating member 9 is provided on the inner wall forming the space 4, far infrared radiation is radiated in the inside of the space 4. Further, water is supplied to a feed-water pipe 5 at a prescribed pressure, and is jetted into the space 4 being in a heated condition through a plurality of small holes formed in the feed-water pipe 5, so that it is easily evaporated. Thus, the physical denaturation of food can be uniformly accelerated to the interior of the food by the steam atmosphere, radiation heat, and far infrared radiation.
