摘要:
A waving lotion for cold waving comprising:(i) a mercapto compound and (ii) an aqueous mixture obtained by heating (a) at least one compound selected from the group consisting of the compounds having the general formulae (I) to (XX), ##STR1## wherein R.sub.1 is hydrogen or an electron attractive group, R.sub.2 is hydrogen or an alkyl group having 1 to 4 carbon atoms, and R.sub.3 is hydrogen, a hydroxyl group, or a methyl group and (b) at least one cyclodextrin selected from the group consisting of .alpha., .beta., .gamma., and .delta.-cyclodextrins in an aqueous phase at a mole ratio of (a):(b)=1:9-1:1 at a temperature of 50.degree. C. to 100.degree. C.This waving lotion has no substantial mercaptan odor and generates no substantial or less of a mercaptan odor when applied to the hair.

A thermoelectric transducer includes a thermoelectric device assembly and a pair of heat exchanging member assemblies arranged at both sides of the thermoelectric device assembly. The thermoelectric device assembly includes a plurality of P-type thermoelectric devices, a plurality of N-type thermoelectric devices, a first holding plate for holding the thermoelectric devices, and a plurality of electrode members for electrically connecting the thermoelectric devices. Each of the heat exchanging member assemblies includes a plurality of heat exchanging members provided in correspondence with the plurality of electrode members, and a second holding plate located for holding the plurality of heat exchanging members. Each of the plurality of electrode members has an outer periphery that contacts one surface of the second holding plate in a state where the electrode member is connected to the heat exchanging member.

A method of manufacturing a grooved pipe includes a pressing step and a longitudinally displacing step. The pressing step presses a grooving tool toward an outer surface of a wall of a pipe in a radially inward direction of the pipe at a location, which is separated by a predetermined distance from an end portion of the pipe. The longitudinally displacing is performed by longitudinally displacing at least one of the grooving tool and the pipe relatively in a longitudinal direction of the pipe while pressing the grooving tool toward the outer surface of the wall of the pipe to form a groove portion, which is recessed from the outer surface of the wall of the pipe. The method is suitably used for forming an inner pipe of a double-wall pipe.

A double-wall pipe includes an outer pipe, and an inner pipe disposed inside the outer pipe. An outer wall of the inner pipe has thereon a ridge portion, which defines a groove portion extending in a longitudinal direction of the inner pipe. The outer pipe and the inner pipe are bent to have a straight portion extending straightly, and a bend portion bent from the straight portion. In the straight portion, the outer pipe has an inside diameter that is larger than an outside diameter of an imaginary cylinder defined by an outer surface of the ridge portion of the inner pipe. Furthermore, the ridge portion of the inner pipe contacts an inside surface of the outer pipe to be readially squeezed and held by the outer pipe, in the bend portion. The double-wall pipe can be suitably used for a refrigerant cycle device.

A mechanism to produce projection images 40A-40G representing a model extraction region and an image sensing region is incorporated in an image sensing unit 1 of an image processing apparatus. A control unit 2 receives an image from image sensing unit 1 to calculate density deviation within the model extraction region. The calculated result is output to a level display unit 27. When the operator determines the position of image sensing unit 1 so that projection images 40A, 40B and 40C representing the model extraction region are projected distinctly on the pattern of the subject to be registered and a high level value is displayed by level display unit 27 and depresses a teach button switch 30, image data within the current model extraction region is registered as the model image.
摘要:
In order to apply pressure and heat to a sheet material as required in the manufacture of a laminated sheet material, the sheet material is conveyed in through an entrance opening of a pressure vessel, along through an interior space thereof, and out through an exit opening thereof, substantially filled with a pressure medium which is maintained at a temperature above its melting point in the interior space of the pressure vessel, but is maintained at a temperature below its melting point in the entrance and exit openings of the pressure vessel, so as to accomplish sealing in such zones by solidification of the pressure medium, whereby enabling continuously to treat a long sheet material under constant application of pressure and heat over a relatively long time period in which respective portions of the sheet material traverse the pressure vessel.
