Filed: 1993-05-11
Abstract: PURPOSE:To obtain a mold not impaired in strength, good in dimensional accuracy, free from a sink and having a smooth surface by adding a prescribed amt. of air bubbles to the resin layer of a resin mold. CONSTITUTION:A resin mold has a resin layer formed as a molding surface layer by the transfer from a model and can also have a reinforcing layer other than the resin layer. The amt. of air bubbles contained in the resin layer is set to 3-20vol.%. The number of contained air bubbles with a diameter of 200mum or less is pref. 30% or more of the total number of air bubbles. By this constitution, no sink is generated at the time of the molding of the resin mold and the transfer property from the model is excellent and the necessity of repairing after demolding is eliminated.

CONSTITUTION:An information retention time period t of MOS dynamic RAM shows such thermal dependency as expressed by t=tOeE<a/>KT... (1), wherein t0 is a specific constant, K is a Boltzmann constant, T is a temperature in an active region, and Ea is an activation energy. The dependency of the information retention time period on an ambient temperature is measured by a prescribed signal pattern, and the activation energy in the formula (1) is determined. Then, the thermal resistance R is determined from the consumed power PH in a test signal pattern SH for a large consumed power and from the consumed power PL in a test pattern SL for a small consumed power, and from information retention time periods tH and tL. The thermal resistance is calculated by conducting the operation of R=DELTAt/(PH-PL), where DELTAt is the difference in temperature between the patterns SH and SL.
