Patent EP-0280536-A2 (EP)
Inventor: OGURA TSUNEO C O PATENT DIVISI
IPC: H01L29/744
Filed: 1988-02-24
Abstract: There is disclosed a specific turn-on/off driving technique for an insulated gate thyristor which has a first gate electrode (24) insulatively provided above a first base layer (14) and functioning as a gate (G1) of MOSFET (Q), and a second gate electrode (G2) formed on the second base layer. To drive the turn-on of the thyristor, a first voltage for conducting MOSFET (Q) is applied to the first gate electrode (G1), while substan­tially simultaneously a second voltage for forwardly biasing between the second base layer (14) and a second emitter layer (18) is applied to the second gate elec­trode (G2). To turn-off drive the thyristor (10), a third voltage for reversely biasing between the second emitter layer (18) and the second base layer (16) to stop the operation of the thyristor is applied to the second gate (G2), while the MOSFET (Q) is kept conduc­tive. The thyristor starts turning off in response to the voltage application. At this time, charge carriers exhausted from the second emitter layer (18) are allowed to flow into the first base layer (14) through the chan­nel region (CH) of the MOSFET (Q), thereby suppressing the local concentration of the turn-off current in the thyristor (10).

Abstract: Compositions which cure by a platinum-catalyzed reaction between silicon-bonded hydrogen atoms and silicon-­bonded, aliphatically unsaturated hydrocarbon radicals have improved pot-life and cure-rate characteristics when a catalyst-inhibiting amount of a diorgano fumarate compound is added to the composition. Solventless coating compositions containing a dialkyl fumarate, a methylhydrogenpolysiloxane and a methylpolysiloxane bearing hexenyl radicals are particularly useful as adhesive-release coatings for acrylic-based pressure sensitive adhesives, applied in-line.

Abstract: Useful materials for diagnostic tests, affinity chromatography, enzymatic reactions and immunoassays are prepared by covalently attaching reactive compounds containing reactive amino or sulfhydryl groups to polymeric particles having carboxyl groups on the outer surfaces. Such reactive compounds include biologically reactive species, such as enzymes, polypeptides and proteins. This attachment is carried out using carbamoylonium compounds which react with the carboxyl groups to form intermediate reactive groups which then react with the amino or sulfhydryl groups to form a covalent linkage between particle and reactive compound.

Abstract: The process and the related equipment are based on two resin packed ion exchange columns (4, 10) through which the juice (S) to be defecated is flowing. 
     In the first column (4) the juice is partially defecated through ion exclusion thus producing molasses (M) with a satisfactory com­mercial value, while the defecation process is completed in the second column (10) with separation of the non-sugar residue and recovery of various sugars and non-sugars having a high market value. 
     Treatment on two columns reduces processing time and/or the quantity of resin necessary as compared with one column processes. Polluting waste water is thus completely eliminated.

Abstract: The connector housing (12) has a latch structure (30) releasably engageable with corresponding structure (28) on a mateable electrical connector housing (22). The latch structure (30) resiliently and deflectably extends from a base (34) moulded unitarily with the housing (12). Ribs (46,48) (see Fig. 2) extend from the surface (32) of the housing (12) adjacent the deflectable end of the latch structure (30) to prevent the entry of cables or the like into the space between the latch structure (30) and the housing (12) thus entangling and "fishhooking" the cables. The ribs (46,48) for preventing such fishhooking have arms (52,54) engageable with the latch structure (30) to prevent overstressing of the latch structure by bending in a direction away from the surface (32). Side walls (160,162) (see Fig. 5) disposed in spaced relationship to the latch structure (30) may further prevent overstressing of the latch structure (30) by side way deflection and also fishhooking of adjacent cables. In a still further embodiment the latch structure (30) is in the form of a deflectable beam (210) (see Fig. 8) having both ends fixed, the beam being formed integrally with anti-fishhooking ribs (226,228) at its end remote from its base (214).
