摘要:
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. A door for a conditioner is also described which comprises a substrate having provided on at least one surface thereof a sealant layer which comprises the polyurethane foam for sealant.

According to the present invention, in a casing having a casing member made of resin and a porous elastic member affixed onto the casing member, there is formed a thick wall portion, which is thicker than the other portions, at a bending corner portion formed between wall surfaces of the casing member. In this way, when the resinous casing member is molded, the resin in a melted state flows along a surface at an opposite side of the elastic member (at a side of an affixing surface between the casing member and the insulator), in a space for forming the thick wall portion. Therefore, the resin in the melted state is prevented from flowing to press upward an end portion of the elastic member at the corner portion. Accordingly, the defective "reversing" is prevented so that the elastic member can be affixed on the wall surface of the casing member satisfactorily.

摘要:
The present invention provides with a terminal having a monitoring period changing function for changing the value (monitoring period) of a no-traffic monitoring timer of the terminal by feeding back the information on radio signal conditions, and a no-traffic monitoring function for changing the status of the call of the terminal to “a disconnected state for only receiving radio signal from a base station” depending on the value (monitoring period) of the no-traffic monitoring timer based on the information fed back.
摘要:
The present invention provides a surface-reading apparatus that includes a subject-flexing mechanism and a surface-reading component. The subject-flexing mechanism causes a subject to flex in one of a convex form and a concave form. The surface-reading component reads a characteristic of a surface condition of the subject that has been flexed by the subject-flexing mechanism. The surface-reading component can includes an optical reading component that optically reads the characteristic of the surface condition of the subject. The optical reading component may be a reflected light-reading component that reads the characteristic of the surface condition of the subject with reflected light or may be a transmitted light-reading component that reads the characteristic of the surface condition of the subject with transmitted light.
摘要:
A lighting system includes a fluorescent lamp 4 and a main body 1 for attaching the fluorescent lamp 4 thereto. The main body 1 is provided with a socket assembly 6 for the attachment of the fluorescent lamp 4, and an electronic ballast 7 for operating the fluorescent lamp 4 at dimmed levels (as well as at the full light level). The fluorescent lamp 4 is composed of a discharge tube formed of four U-shaped glass tubes that are connected together to form a square in plan view. Each glass tube has an inner diameter of 13.5 mm, and the discharge tube is filled with a rare gas containing neon and argon (at 50:50 ratio by volume).
摘要:
An object of the present invention is to provide, without increasing the costs or decreasing the quantity of light, a fluorescent lamp that is less likely to have the bridge and the constituent tubes damaged while being handled and has improved handleability, as well as to provide a manufacturing method therefor. It is arranged so that the distance between the first and second constituent tubes gradually becomes smaller from the base side of the lamp toward the turning portion side of the lamp where the discharge paths turn. It is arranged so that the value of D2/D1 is within a range of 0.05 to 0.70 inclusive, where D1 is the distance between the first and second constituent tubes being measured at the bridge connecting points on the base side, and D2 is the shortest distance between the first and second constituent tubes on the turning portion side.
