Title: Transporting appartus for boards
Inventor: HARTMUT VENGR
IPC: H05K13/00
Filed: 1988-10-13
Granted: 1998-04-24
Abstract: A transport apparatus for boards or workpieces in board form, for example printed circuit boards which are to be coated with plastic, for example UV curable plastic, has advancing means for the transport of the boards and grippers or clamps for seizing the board edges during the transport and advancement of the boards. In order to avoid a risk of damaging the sensitive board surfaces, in particular when transferring the boards from one conveyor to the other, the gripper or grippers or clamps is/are attached to a holding element or rack, releasably coupled to the transporting or advancing means of the apparatus. This holding element remains connected, via its grippers to the board during the complete transport of the latter and can be transferred and reloaded together with the board held by it at transitions from one advancing means to another or from one processing station to the other. The handling of the boards is thus in practice directed instead to its holding elements and consequently the risk which this handling entails is kept away from the boards.

Abstract: The hydrolysable monomer of formula(I), for a microorganism repellent paint binder is produced by reacting a multivalent metal oxide contg. an anion gp. of formula M-(A)n/m with an unsatd. monomer contg. an (in)organic acid or its salt of formula(II) in the solvent i. e. benzene, toluene, acetone, isopropanol or ethylacetate at 30-120 deg. C. In the formulas, R is -H, -CH3, or -Cl; X is -C(O)-, -S(O)2- or -C6H4S(O)2-; M is at least two valence metal; n is metal ion number; U is -P(O)(OR1)2- or -C(O)R2-; R1 and R2 are each C1-10 alkyl; Z is -OH, -ONa, -OLi or -Cl; A is -OH, -CN, -SCN, -NO3, -F or - Cl; m is A ion number. The binder is produced by solution polymerizing the monomer with a radical initiator i. e. benzoyl peroxide in the solvent at 50-120 deg. C. The paint prevents sticking of marine creatures to the ship bottom.

Title: Method for controlling temparature gradient in according with increasing the length of single crystil by vb
Inventor: KO HAN-JUN
IPC: C30B11/02
Filed: 1992-07-28
Granted: 1995-10-24
Abstract: The method in characterized in that the length of mono-crystal is increased by increasing the T5 value by means of changing the temperature(Th) of the high temperature portion into a first lower temperature(Th') as well as changing the temperature(Tc) of the low temperature portion into a second lower temperature(Tc') in a state maintaining the same temp. gradient and crystal growth speed as the higher temperature(Th) than the m.p. of GaAs and the lower temperature(Tc) than the m.p. of GaAs.
