Abstract: A particle counter for measuring the number of floating particles contained in a sample to determine the particle concentration therein comprises: a memory section 11 for storing a discrete value C per unit of time based on the maximum particle number concentration set in the specification in advance; an operation processing section 12 for comparing a discrete value M per unit of time to be actually counted to the discrete value C per unit of time stored in the memory section 11; and an output section 4 for outputting the information based on the comparison results of the operation processing section 12.

Abstract: An object of the present invention is to provide a shrinkable film excellent in dimensional stability at a temperature of 60° C. and having good shrink properties in a temperature of 100° C. and 120° C. A low-temperature shrinkable film includes a film composed of at least one layer including at least one ethylene-?-olefin copolymer (A) with a density of from 0.870 g/cm3 to 0.920 g/cm3 and at least one ethylenic copolymer (B) having a main peak below 110° C. in the 2nd fusion behavior of differential scanning calorimetry, wherein the proportion of the heat of fusion at 100° C. or below to the total heat of fusion is from 50% to 100% in the 2nd fusion behavior of differential scanning calorimetry for ethylene-?-olefin copolymer (A); the proportion of the heat of fusion at 100° C.

Abstract: Disclosed is a cross-linked heat shrinkable film comprising an ethylene polymer resin which has a gel fraction of 5-40%. Furthermore, this film contains a glycerin fatty acid ester surface active agent in an amount of 2.0-8.0% by weight based on the total weight of the ethylene polymer resin, said surface active agent being present in an amount of 3.0-20.0 mg/m2 on at least one surface of the film. This film has characteristics adaptable to speeding-up of continuous packaging machines, namely, a proper coefficient of dynamic friction and hot tack sealability, with maintaining appearance of the film after being shrunk, such as heat shrink characteristics, fog resistance and gloss.

Abstract: In an apparatus and method for generating a signal corresponding to a torque applied to a rotatable shaft according to the present invention, a compensation for a change in temperature causing the change in characteristics of the circuit elements including a magnetostriction shaft is carried out. In a preferred embodiment, a posistor whose resistance value is increased as the temperature is increased with respect to a normal temperature (20.degree. C.) is used for an input temperature sensitive resistor of an inverting amplifier connected to a center tap of a half bridge circuit constituted by a pair of coils constituting a torque sensor having the magnetostriction shaft so that an amplification factor of the inverting amplifier is adjusted so as to accord with the change in the temperature.
