Abstract: Provided are an anchor fixing agent which can fill up fine concave and convex portions present on the inner surface of a hole formed in a base material and can maintain great strength, in particular, even after the lapse of a long period of time; an anchor fixing agent ampule; and a method for fixing an anchor. An anchor fixing agent which comprises an alumina cement, a lime and/or a portland cement, and water. Preferably, it further comprises an agent for the retardation of setting and light magnesia. The anchor fixing agent ampule holds a solid component and a liquid component in the anchor fixing agent in the state wherein the components are separated from each other.

Abstract: The antifreeze of the present invention is including propylene glycol, first material, and second material. The first material is normal aliphatic dicarboxylic acid in which number of carbon atoms is from 10 to 12, salt of the normal aliphatic dicarboxylic acid, or mixture thereof. The second material is benzimidazole compound which has a benzimidazole skeleton, salt of the benzimidazole compound, triazine compound which has a triazine skeleton and has a mercapto group, salt of the triazine compound, or mixture thereof. Such antifreeze has less environment load than antifreeze including ethylene glycol. Furthermore, such antifreeze does not cause metal to corrode more than the antifreeze including ethylene glycol.

Abstract: A coin selector apparatus of the electronic type for a vending machine into which a coin thrown in the selector is moved through electromagnetic fields each produced by a coil assembly constituting a part of an oscillator oscillating at a predetermined frequency. Variations in the output oscillation frequencies of the oscillators are detected and utilized for discriminating between coins with respect to their shape, material and thickness.Further, a selected oil assembly is provided with a coil gap that is changeable in association with the closing and opening of the coin passage to cause a variation in the corresponding output oscillation frequency and to produce a coin rejection signal.

Abstract: A vibrator unit for use in a timepiece comprises a vibrator mounted within a ceramic case. A glass lid is airtightly sealed to the ceramic case by means of a soldering washer soldered between opposing surface portions of the lid and case. The soldering washer consists essentially of 90Sn-10Au solder alloy which enables formation of the airtight seal at lower and/or shorter soldering temperatures than would be the case with conventional solder alloys thereby avoiding an increase in the equivalent impedance of the vibrator unit which would otherwise occur. As the equivalent impedance can be maintained at a low value, the vibrator unit can therefore be made smaller without adversely affecting the equivalent impedance which is maintained below 350 K.OMEGA..
