Abstract: A contact lens sterilization device has a case which is generally made of synthetic resin having defined therein: a bottom chamber for receiving the heating element; a middle chamber for receiving a contact lens; a top chamber for receiving an electronic circuit for controlling the heating element therein so as to achieve a better thermal separation between the top chamber and the bottom chamber. A heating element which may be a PTC semiconductor device is secured to the lower surface of the wall separating the middle chamber and the bottom chamber by way of a heat transmission plate and secured by a holding plate and columns appending from the separation wall. The two electrodes of the heating element may be electrically in contact with the heat transmission plate and the holding plate, respectively.

Abstract: The performance of an asphaltic paving material can be greatly improved when the paving material is prepared by first coating the particles of the aggregate material with a molten phenolic resin and then mixing the thus resin-coated aggregate material with asphalt and the like bituminous material. The phenolic resin is preferably modified with a phenoxy resin.

Abstract: The process for preparing a resin-coated casting sand by coating sand grains with a binder comprising a liquid phenolic resin component and a polyisocyanate component, the improvement of which comprises coating sand grains with an organic solvent prior to coating of the sand grains with the binder, thereby prolonging the bench life of the resulting resin-coated casting sand and enhancing the strength of a casting mold prepared from this resin-coated casting sand. Furthermore, this process enables the utilization of sand of a low grade or reclaimed sand having a high alkaline component content, that has not been used in the conventional process, and the supply of an excellent resin-coated casting sand which is capable of providing a casting mold having a high strength and has a long bench life.

Abstract: The invention relates to improvements of RCS and casting molds therefrom. The improvement resides that the resinous coating contains halogen-containing compound(s) which accelerate(s) carburizing of the resin during under heat subjected to the molten metal pouring step. Further, the resin coating comprises certain amount of pulverized metal capable of reacting under heat with separated halogen or halogen compound during the casting step and for avoiding ferrous element(s) in the castings and/or the mold(s).

Abstract: An epoxy resin composition comprising(1) about 20 to about 80% by weight of a solid epoxy resin, and(2) about 80 to about 20% by weight of a solid resole-type phenolic resin having a softening point of about 70.degree. to about 90.degree. C., a gel time at 150.degree. C. of at least about 80 seconds and a methylol index of about 25 to about 45, said phenolic resin being a condensation product of 1 mol of a phenol with 1 to about 4 mols of an aldehyde.

Abstract: A nebulization control system for an ultrasonic nebulizer comprising a variable pulse oscillating circuit, an ultrasonic vibrating circuit and an ultrasonic vibrator is described. The ultrasonic vibrator is caused to vibrate alternatingly between a high level which is sufficient to nebulize a fluid and a low level which is insufficient to nebulize the same. The ratio of duration of the high level to the low level and/or the amplitude of vibration at the high level is variable. This arrangement permits a precise control of nebulization quantity and assists in the production of a fine, uniform mist of fluid.

Abstract: Disclosed is a dripping fluid level detector comprising a pair of electrodes oppositely disposed around a drip chamber of a supply passage of dripping medical fluid and a detecting circuit which detects the remaining amount of medical fluid according to changes in the electrostatic capacity caused between said pair of electrodes.
