M v  is a vinyl unsaturated isocyanate. 
     These vinyl unsaturated polymers are useful, either by themselves or in combination with other copolymerizable vinyl monomers, as heat or UV-curable coatings or glass, plastic, wood, paper, textiles, metal or ceramics, said coatings possessing low surface energies and low refractive indices. They are especially useful as UV-curable hydrophilic coatings and water-swelling biocompatible polymers, especially fully molded highly oxygen-permeable contact lenses.

Abstract: In a method for controlling an external machine by a voice command, a voice pattern which is extracted from a voice supplied through a microphone is compared with reference voice patterns to pick up one of them which corresponds to a certain voice command to control an external machine, and a similarity between the voice pattern and the reference voice pattern is calculated. Then, a control signal is supplied to the external machine after a waiting time passes. The waiting time is determined dependent on the similarity such that the waiting time is relatively long when the similarity is low and is determined relatively short when the similarity is high, so that an operator has a sufficient time to judge whether the voice command is the desired one.

IPC: B32B27/00

Abstract: A method of producing a multiphase polymer is disclosed whereby the phases have the same chemical structure but have different morphological states and thus different properties. This is achieved by forming a mixture of precursors of the polymer, at least one of the precursors having a reaction rate higher than the other precursor or precursors in the mixture. The precursor having the highest reaction rate is then converted to obtain a composite of a polymer and the precursors that are not polymerized. This mixture might also be formed by mixing a soluble polymer with its precursor. The polymer/precursor composite is processed to obtain the structure having different morphological states by either choosing the reaction conditions to convert the unconverted different morphological states by either choosing the reaction conditions to convert the unconverted precursors such that the obtained polymer differs in it morphology/properties from the first obtained polymer or by applying stress to the composite and then converting the still unreacted precursor or precursors in the composite such that different morphological states are obtained.

The housing is provided with a front cover for covering the tape. The tape is exposed by an upward rotation of the front cover (28). The front cover is upwardly rotated when a slider (30), which is slidably attached to the housing, is slid rearward with respect to the housing. The slider (30), which is in engagement with an engaging member, is slid by relative movement of the engaging member and the housing. The slider is locked to the housing by a locking member, which unlocks the slider when the engaging member is engaged with the slider.

Abstract: A video signal gradation corrector used in a television receiver or the like is disclosed which can prevent the destruction of the gradation of the black side and the floating of the luminance level of the black side and/or an excessive increase of the luminance level of the white side or which can be realized with a small circuit scale. A histogram operating circuit (3) includes an average luminance level detecting circuit (99). A constant (100) is subtracted from an output signal of the average luminance level detecting circuit by a subtractor (101). The result of subtraction is multiplied by a constant by a constant-multiplication circuit (102). A lower-limit limiter circuit (103) limits an output signal of the constant-multiplication circuit to a signal having a value not smaller than 0. An output signal of the lower-limit limiter circuit is provided as an accumulation start luminance level, thereby enabling a gradation correction in which the floating of the luminance level of the black side and the destruction of the gradation of the black side are prevented. Also, the average luminance level and a constant (110) may be added by an adder (111). The result of addition is multiplied by a constant by a second constant-multiplication circuit (112) and is limited to a certain value by an upper-limit limiter circuit (113). An output signal of the upper-limit limiter circuit is provided as an accumulation stop luminance level, thereby enabling a gradation correction in which an excessive increase of the luminance level of the white side is prevented to suppress the blooming of a CRT.

Abstract: A single mask (30,56,64,70) is used to form a tapered nozzle (48) in a polymer nozzle member (46) using laser ablation. In one embodiment of the mask, clear portions of the mask, corresponding to the nozzle pattern to be formed, each incorporate a variable-density dot pattern (36), where the opaque dots (36) act to partially shield the underlying polymer nozzle member from the laser energy. This partial shielding of the nozzle member under the dot pattern results in the nozzle member being ablated to less of a depth than where there is no shielding. By selecting the proper density of opaque dots around the peripheral portions of the mask openings, the central portion of each nozzle formed in the polymer nozzle member will be completely ablated through, and the peripheral portions of the nozzle will be only partially ablated through. By increasing the density of dots toward the periphery of each mask opening, the resulting nozzle may be formed to have any tapered shape. Other mask patterns are also described.
