摘要:
A thin film electric heater employs voltage and current suppressed below values of an allowable voltage and an allowable current. The thin film electric heater includes a thin film electric resistor to be formed directly on a surface of an object to be heated and is energized to effect heating. The resistor has a surface resistivity r, expressed by r=.rho./t (where .rho. is the volume resistivity of the thin film electric resistor and t is the film thickness of the thin film electric resistor), within a range to achieve the heating function of the thin film electric heater while the values of voltage and current applied to the thin film electric heater are suppressed below the values of the allowable voltage and the allowable current.

A dye composition for keratinous fibers is disclosed. The composition comprises a developing substance and, as a coupling substance, a 3,5-diaminopyridine derivative of the following formula (I), ##STR1## wherein R.sup.1 is an alkoxy group or a group ##STR2## wherein R.sup.2 and R.sup.3 may be the same or different and individually represents a hydrogen atom or a hydroxyalkyl group, R.sup.4 a hydroxy, alkoxy, or hydroxyalkyl group, and n is a number of 1-4; or a salt thereof. The composition is capable of dyeing keratinous fibers such as hairs in blue color with a high vividness and with resistances to the light, color change, and discoloration due to shampooing.

摘要:
An apparatus for piling rod-shaped articles in a container, in which a hopper member having at least one levelling means such as a swing pin is employed in combination with a push means. The rod-shaped articles temporarily collected in the hopper member are pushed out into the container by the push means at least every one layer thereof thereby to make an orderly pile of the rod-shaped articles in the container.
