摘要:
Disclosed is a biodegradable resin composition containing at least one biodegradable organic high molecular compound, a flame retardant additive containing a phosphorus-containing compound, and a hydrolysis suppressing agent suppressing the hydrolysis of the at least one biodegradable organic high molecular compound. An aliphatic polyester resin is polylactic acid, polycaprolactone, polyhydroxy lactic acid, polyhydroxy valeric acid, polyethylene succinate, polybutylene succinate, polybutylene adipate, polymalic acid, polyesters synthesized by fermentation, or a copolymer containing at least one of them. A polysaccharide is cellulose, starch, chitin, chitosan, dextrane, a derivative of at least one of them, or a copolymer containing at least one of them.
摘要:
A biodegradable plastic material that can provide long-term reliability, even though being formed of a biodegradable polyester material, and a shaped article obtained therefrom. A biodegradable plastic material is treated with a compound being capable of reacting with active hydrogen in the biodegradable plastic, and a shaped biodegradable plastic article obtained from the material.
摘要:
A water-immersed switch which does not conduct electricity in the absence of a dielectric liquid, such as water, and which conducts electricity in the presence of the dielectric liquid. The water-immersed switch includes a modified copolymer containing acrylonitrile and at least one of styrene and/or a conjugated diene, as constituent units, and acidic groups introduced into said modified copolymer, and a plurality of electrically conductive electrodes.
摘要:
A recycling method which enables recycling of a high-quality regenerated styrene resin. A waste styrene resin material is dissolved in an organic solvent boiling at a temperature lower than 200° C. and having solubility not less than 15 wt % at room temperature to prepare a solution of the waste styrene resin material. The resulting solution is freed of volatile components on heating in vacuum to remove the organic solvent to set the amount of the residual solvent in the styrene resin to 0.4 wt % or less to recycle the resulting styrene resin as a regenerated styrene resin.
摘要:
A waste processing apparatus which can easily and efficiently process waste, a waste recovery system using this apparatus and a liquid container ideal for use with the waste processing apparatus and waste recovery system. The waste processing apparatus comprises a processing part for processing supplied waste (for example foam polystyrene) with a processing liquid (for example limonene) and a storing part for storing produced liquid (for example limonene containing dissolved foam polystyrene) produced in this processing part and provided with a removable liquid container constructed to both supply processing liquid to the processing part and receive produced liquid produced by the waste processing apparatus. In the waste recovery system, the liquid container is removed from the waste processing apparatus after receiving the produced liquid and carried to a waste recycling apparatus, the produced liquid is transferred from the liquid container into the waste recycling apparatus, waste or waste and processing liquid is recovered from the produced liquid by the waste recycling apparatus and the empty liquid container is filled with new or recycled processing liquid and returned to the waste processing apparatus again.
摘要:
A method of manufacturing a polyelectrolyte having the step of sulfonating polystyrene resin in a state where the polystyrene resin has been dissolved or dispersed in solvent composed of alicyclic compounds.
摘要:
A 3-element series parallel resonator, which performs series resonance and parallel resonance at a predetermined frequency by a combination of three elements including an inductor and a capacitor of concentrated constants, is used as a filter. This design can reduce the circuit constant and permits a filter to be formed on a semiconductor substrate. Accordingly, various micro-wave devices, such as an amplifier which requires a filter, a frequency converter, a multiplier and signal switcher, can be designed into an MMIC on a single chip.
