摘要:
A spout fitting apparatus being fixed easily to the spout of a container such as a plastic bottle and a bottle such that the cap of an existing container can be employed, as it is, under fixed state without falling into the container, and fluid flows out smoothly from the container at the time of pouring while preventing a hiccoughing phenomenon due to interruption of fluid flow and preventing fluid from scattering to the surroundings of the container, comprising: a locking portion 1 locking to the spout of a container, an falling-prevention stopper 2 provided at the upper edge of the locking portion 1 and preventing the fitting from dropping into the container, a partition wall 3 bonded to the locking portion 1 and separating the fluid outflow path from the inside of the container and an air inflow path from the outside of the container, and an air inflow conduit 4 for extending the opening from the air inflow path side of the partition wall 3 and connecting it to the inside of the container. A container is also provided.
摘要:
A white film for a reflecting structure for surface light sources, which contains voids inside it and has a light stabilizer-containing coating film formed on at least one surface of it, is aged little with time and its brightness lowers little even when used for a long time. The white film ensures good image quality of display screens for a long time, and it is favorable to reflecting sheets and reflectors in edge light-type and direct back light-type surface light sources for liquid crystal display screens.
摘要:
There is realized a control device capable of speeding up an output response without causing deterioration in the resolution of a time-proportional output. The control device controls a control object at a ratio of ON-time to OFF-time for a time-proportional output. The control device comprises a PID computation unit for executing PID computation of deviation between a set value and a measured value from the control object, an integrator for sequentially adding up control output values each representing the result of the PID computation executed by the PID computation unit, an ON/OFF determination unit for determining whether the time-proportional output is turned ON or OFF on the basis of an integrated value of the integrator, and a time-proportional output unit for turning the time-proportional output ON/OFF on the basis of a determination value of the ON/OFF determination unit.

摘要:
A chlorella extract, which is useful as an additive for health food or pet food, is obtained by the steps of adding 1-10 parts by weight of a cyclodextrin solution to 100 parts by weight of an extract obtained by concentrating a hot water extract of a powdery chlorella alga by a factor of two to five, kneading the thus obtained mixture under reduced pressure at 60.degree.-90.degree. C. for 10-24 hours to give a cyclodextrin clatharte and then drying and powdering the clathrate.
摘要:
A shrinkage-reducing dispersing agent for use in cementitious compositions such as concrete and mortar comprising a graft polymer which is a polycarboxylic acid or a salt thereof, having side chains derived from at least one species selected from (a) oligoalkyleneglycol and/or polyalcohol and (b) polyalkylene glycols or derivatives thereof.

A generator set includes a permanent soundproof housing for housing a portable engine generator therein. The portable engine generator has wheels for moving the same and can be operated in the permanent soundproof housing. The portable engine generator can be taken out of the permanent soundproof housing by pulling the portable engine generator out of the permanent soundproof housing in a direction transverse to a direction of advance of the wheels, and thereafter moving the portable engine generator in the direction of advance of the wheels.

摘要:
A fish feed additive is used which contains .beta.-carotene containing Dunaliella algae powder stabilized against oxidation and migration into the water. The fish feed is prepared by mixing 100 parts by weight of a Dunaliella algae powder with 15-50 parts by weight of a cyclodextrin while stirring. The final fish feed is obtained by blending 10 parts by weight of this additive with 200-500 parts by weight of a common fish feed. The fish feed additive is in the form of dry fine granules. The fish feed additive effectively promotes growth and delivers .beta.-carotene to the fish.
