Abstract: Disclosed is a respiration leading system which can leads a living body to respire so that relaxation is effectively induced without any physiological load even if a respiration exercise feedback is not employed. This system comprises a control unit and a sense-stimulating unit. The control unit makes the sense-stimulating unit change the output energy for stimulating a sense of the living body so that the living body is induced to inhale and exhale as a physiological reaction. The energy change is done within the range of a respiration period x(sec) and a parameter y defined as 2 sec<x<12 sec and 0.85<y<1.45 (a region x≦4 sec and y≧1.3 is excluded). The parameter y is a ratio of exhaling time to inhaling time. The energy output in the first half period corresponding to either inhaling or exhaling and the energy output in the latter half corresponding to the other, induce the living body to respire.

Abstract: In an illumination control method of the present invention, illumination of an appreciation space is controlled in association with an image displayed on an image display device so that a realism of the image displayed on a screen of the image display device can be enhanced, where an appreciator appreciating the image is in the appreciation space. More specifically, one or more light sources provided in the appreciation space is controlled so that at least one parameter of a level, a light color, a luminous intensity distribution, and a direction of illumination to the appreciation space is made substantially coincident with a corresponding parameter of a virtual image space imaginarily created from the image displayed on the image display device.

Abstract: In a lighting system capable of varying luminance of the light emitting surface periodically used for adjusting rhythm of breathing of an observer when he wishes to fall asleep, a light source is controlled in a manner so that variation of the luminance “L” per a unit time in the vicinity at a time tMAX when the luminance “L” takes the largest value in one period becomes larger than the variation of the luminance “L” per the unit time in the vicinity at a time tMIN when the luminance “L” takes the smallest value.

Abstract: In a light irradiation method, a main irradiation section forming a target and a sub irradiation section for providing sub illumination light to or from at least one of a background and a neighborhood of the target are provided, and a perceived brightness of the target is varied by performing time-wise control of an intensity of the sub illumination light emitted by the sub irradiation section. When applied to an illumination system wherein the main irradiation section is an illumination source, or to an indication system wherein the main irradiation section is an indication lamp, a perceived brightness of the illumination source or the indication lamp is decreased by increasing the intensity of the sub illumination light, while increased by decreasing the intensity of the sub illumination light.

Abstract: A polyurethane foam for a sealant is disclosed which is produced from a composition prepared by compounding reaction mixture comprising a polyisocyanate ingredient and a polyol ingredient with a given amount by weight of an ozone inhibitor ingredient. A sealant of a predetermined shape is obtained from the foam. The polyol ingredient may be one ordinarily used for producing soft polyurethane foams, but especially preferably comprises a polyester-polyether polyol having both an ester segment and an ether segment in the molecular chain. The foam has excellent resistance to ozone deterioration and hence retains a sufficient air permeability required of a sealant for practical use. Further, the foam suffers little decrease in tensile strength from the initial value because it also has excellent resistance to deterioration by moisture and heat, i.e., high hydrolytic stability.

Abstract: A system for replacing a filled cloth roller with an empty cloth roller for a loom is comprised of two rotatable shafts which are oppositely disposed and respectively supported by side frames of the loom. Each rotatable shaft is fixedly provided with an engaging member engageable with an end section of the cloth roller. The two rotatable shafts are automatically driven to move axially under the action of a pneumatically operated actuator, so that the engaging members are disengaged respectively from the opposite end sections of the cloth roller for the purpose of removing the filled cloth roller from the loom while engaged respectively with the same end sections for the purpose of installing the empty cloth roller to the loom. One of the rotatable shafts is driven from a loom main shaft to rotate the cloth roller, thus taking up a woven cloth on the cloth roller during the weaving operation of the loom.
