Inventor: WEGMANN URS
IPC: H01J37/147
Filed: 1990-09-05
Granted: 1999-03-20
Abstract: In order to utilize a magnet arrangement having a magnetic flux density field for beam guidance in the deflection of a beam of monopolar charged particles, regions of the field having curved field lines, are modified to significantly linearize the field lines in the area of the beam. An additional flux density field is superimposed on the primary flux density field so that the field lines interact in an harmonic synthesis and so that the field lines of the resulting field in the region of interest, extend linearly. In this way, the deflection force on the beam is essentially independent of the beam position in the field direction and in the linearized region.

Title: Method for manufacturing polyurethane foam
Inventor: LEE EUN-HO
IPC: B29C44/00
Filed: 1993-02-18
Granted: 1996-06-28
Abstract: The porous surface polyurethane foam is prepared by (a) putting urethane material such as isocyanate into the mold to control the temperature, (b) foaming and releasing it in the mold. The polyurethane foam comprises less than 60wt% solid phase polymer containing monomer such as acrylonitril, styrene and butadiene with vinyl group and polyol dispersed or grafted at polyether polyol with hydroxide end group. Their molecular weight are 2500-6000 and 2500-5500, respectively. The temperature of hot cure mold is 55-70deg.C at injecting and 60-80deg.C at releasing, and the total manufacting time is about 10-30min.
