The lower shafts(109) of the first link member are surface-supported by the support plate at the standby position where the key top is not pressed. The surface supported portion serves as an element for determining height of the key top.

Abstract: PURPOSE: An economical method for producing polymer concrete composition with good mechanical properties by using recycled pet-based unsaturated polyester resin as binder and waste glass as aggregate or filler. CONSTITUTION: The polymer concrete composition comprises the components of: 5-30wt.% of recycled pet-based unsaturated polyester resin as a binder; 5-30wt.% of filling material such as potassium bicarbonate, fly ash(10-30micrometer size) or waste glass(<0.075mm size) for increase of mechanical strength of hardened products; 40-90wt.% of aggregate, waste glass substituted for natural aggregate, containing 0.075-4.75mm size of fine glass aggregate and/or 4.75-50mm size of coarse glass aggregate. The composition is produced by mixing the above materials and curing mixtures at 50-200deg.C over 24hrs.
