Abstract: A skin resistance measurement device includes a pair of electrode portions provided on an epidermis and a measurement portion configured to measure skin resistance between the pair of electrode portions. The pair of electrode portions has a structure in which drying of the epidermis is naturally performed.

Abstract: A coil end connecting structure for connecting a coil end part extending from a coil winding part formed by winding a flat wire, includes: a narrow-width part which is formed by forming a cut part made by cutting out the coil end part on a tip side at least on one side in a width direction thereof; an end connecting member which includes a cylinder body part in a cylindrical shape and in which the narrow-width part is inserted in an inner cylinder part of the cylinder body part; and a crimp part which crimps the cylinder body part to electrically connect the narrow-width part and the end connecting member.

Abstract: A refrigeration system uses a refrigerant which contains, as a main component, hydrocarbon or HFC-152a. A fluid tube, such as, a gas charge port tube is hermetically connected to a refrigerant flow passage in the refrigeration system for filling at least the refrigerant into the refrigerant flow passage. The fluid tube is sealed against leakage of the refrigerant from the refrigerant flow passage by means of a pinched portion and a squashed portion of a flat-plate shape which extends from the pinched portion to a distal end thereof. The squashed portion may be folded at a plurality of portions for enhancing the sealing effect. Further, instead of the squashed portion, an adhesive may be used for reinforcing the sealing effect provided by the pinched portion. Alternatively or with the use of the adhesive, an elastomer may be used for reinforcing the sealing effect provided by the pinched portion.

Abstract: A porous filter having a pore size of no more than 80 .mu.m is provided in a refrigerant flow passage of a refrigeration system. The filter may be provided in a drier provided in the refrigerant flow passage or in a separate filter casing provided in the refrigerant flow passage. Alternatively, the filter may be provided in the refrigerant flow passage within a sealed casing of a refrigerant compressor which is incorporated in the refrigeration system. The filter is formed of a molded solid material constituted by alumina, silica gel, calcium sulfide and aluminosilicate.

Abstract: Two or more rising pulse waves having different rates of voltage increase are applied to a measuring end of a cable and reflected waves from a fault point on the cable are detected to measure a turnaround propagation time between the measuring end and the fault point. Additionally, ratios of the rates of voltage increase of one pulse wave and the other pulse waves are calculated. A discharge delay time at the fault point is calculated from time differences of the measured turnaround propagation time and the ratios of the voltage increasing speeds and the discharge delay time is subtracted from the measured turnaround propagation time to calculate a real turnaround propagation time.

Abstract: A tape cassette having improved transport capabilties includes frictional sheet members mounted either stationarily or rotatably to impart a frictional back tension on the tape via the tape reels.
