Patent EP-0402948-A2 (EP)
Inventor: HAYASHIDA HAJIME C O YAMAHA CO
IPC: G10C3/06
Filed: 1990-06-15
Abstract: In a sound board assembly for a musical instrument, a plurality of straight-grain wood veneers are joined together in a plane to form a plate unit having front and rear surfaces. Each of the wood veneers has two lateral sides which extend in a direction along the grain of the wood veneer. The lateral sides of the wood veneer serve respectively as a pair of abutments. One of the pair of abutments of one of each pair of adjacent wood veneers is abutted against and joined to one of the pair of abutments of the other wood veneer. A plurality of voids are formed inside of the plate unit. Substantially, the voids are formed along a neutral plane of the plate unit which is in the middle of the two surfaces. Thanks to the voids in the plate unit, the above sound board assembly is capable of sufficiently exhibiting the merit of a woody sound, capable of setting the sound quality artificially and freely, and capable of realizing the woody sound that has more warmth than in the case where high-quality natural woods are used.

Abstract: Provided is a composition having excellent water resis­tance and alkali washability, comprising a polyvinyl alcohol (A), an amino compound or its salt (B), a crosslinking agent (C) and as component (D) at least one water-insoluble and alkali-soluble substance and/or water-insoluble and alkali-­swellable substance. Adhesives comprising this composition are excellent in water resistance and alkali washability, and hence, when used for labels to patch on glass base materials, particularly glass bottles filled with beverages, exhibit high cold water resistance to keep the labels on the bottles when the glass bottles are cooled, and cause the labels to readily be peeled off when the recovered bottles are treated with aqueous alkali solution. Accordingly, the adhesives are very useful particularly for lables for glass bottles containing beverages.

Title: Electrical switch-off snubber circuit for a controllable semiconductor switch
Inventor: HOFGRAEFF HANS G
IPC: H03K17/732
Filed: 1990-08-10
Abstract: Electrical switch-off snubber circuits for controllable semiconductor switches, particularly gate turn-off thyristors, are known in which a series circuit of a storage capacitor and a diode is arranged parallel with the switch. Via a control circuit, a discharge switch is activated which closes a discharge circuit which connects the capacitor to the primary winding of a transformer so that the electrical energy stored in the capacitor can be picked up across a secondary winding of the transformer. It is proposed to construct the control circuit in such a manner, and to connect it to the diode at the input end so that the discharge switch is switched in dependence on the polarity of the voltage across the diode. The transformer is preferably operated as isolating transformer.

Abstract: A method of selectively tuning the bandedge of a semiconductor heterostructure includes forming a disordered region (11) which is spatially separated from a quantum well active region (12), and subsequently annealing the heterostructure so that vacancies/defects in the disordered region (11) diffuse into the quantum well region (12) and enhance interdiffusion at the well-barrier heterojunctions. The tuning is spatially selective when the heterostructure is masked so that exposed portions correspond to regions where bandgap tuning is desirable. The heterostructures of interest are III-V material systems, such as  
 
        AlGaAs/GaAs 
 
, where the active region includes structures such as a single quantum well, a multiple quantum well, or a superlattice.
