摘要:
An instrument captures free thrombi by inhibiting blood coagulation reaction at the stage of primary hemostasis, in which platelets are involved, and at the stage of coagulation thrombus formation, in which blood coagulation factors are involved, thereby securely capturing free thrombi and extending the available time of the instrument.
摘要:
A medical material has a compound firmly immobilized on the surface thereof, which compound is capable of inhibiting both of the blood coagulation reactions in a primary hemostasis stage in which platelets are involved and in a coagulation thrombus formation stage in which blood coagulation factors are involved in a state retaining the anticoagulant activity. The present invention provides a medical material having a hydrophilic polymer compound immobilized on the surface thereof, in which a compound and a copolymer of monomers selected from the group consisting of ethylene glycol, vinyl acetate, vinyl pyrrolidone, propylene glycol, vinyl alcohol and siloxane are bound.
摘要:
A hydrophilic polymer compound includes a polymer compound which inhibits platelet adhesion, and a compound that inhibits blood coagulation reaction, bound to the polymer compound.

A reflecting film is made by forming resin layers on both sides of a metal thin film, and using a colorless, transparent, and optically isotropic material at least in one resin layer. A reflecting film is made by forming a metal thin film on one side of a resin film, and forming a colorless, transparent, and optically isotropic resin coat layer on its surface by printing or other method. A mirror having such a reflecting film is mounted on a frame. A projection type image magnifying apparatus for liquid crystal panel and a projection type image magnifying apparatus for CRT, improved in resolution and contrast ratio, is obtained by using such mirror as an image reflecting mirror.
摘要:
A vision regeneration assisting device for regenerating vision of a patient, comprising: a plurality of electrodes which are stuck and placed into an optic disc of the patient; a storage unit which stores a generation position of a phosphene specific to the patient in association with the first output conditions for the stimulation signal that has caused to generate the phosphene, the storage unit storing various first output conditions for the stimulation signals and the generation positions of the phosphenes caused by the stimulation signals based on the various first output conditions in association with each other; a processor which sets second output conditions for the stimulation signal based on image data obtained by an external photography unit and the generation positions of the phosphenes stored in the storage unit, and converts the obtained image data into data for the stimulation signal based on the set second output conditions.

A field sequential color display device includes a color wheel assembly. The color wheel assembly has a color wheel which is divided into a plurality of color regions and a motor for rotating the color wheel. The motor contains a sensor for detecting rotation of the motor and the sensor outputs at least one pulse per one revolution of the motor. The color wheel assembly also has a spatial light modulator for displaying image data that is driving in synchronization with the pulse output by the sensor.

The present invention provides a bright light transmission screen and light diffusion panel. Am amtireflective film is disposed on the surface of a lenticular lens sheet substrate included in a light transmission screen. The antireflective film is made from a high polymer compound of a low refractory index and has a thickness that is different from .lambda./(4n). The antireflective film may also be disposed on a Fresnel lens sheet substrate or a light diffusion panel substrate.
摘要:
A method for improving visual ability of even a patient's non-operative eye is provided. The electrical stimulation method for improving vision of patient's eyes comprises placing an electrode in one of patient's right and left eyes, and outputting an electrical stimulation pulse signal from the electrode placed in the patient's eye under a predetermined stimulation condition to stimulate cells constituting a retina or optic nerve, thereby improving vision of the other patient's eye with no electrode being placed.
摘要:
A projection display device includes a condensing unit and a shading unit. The condensing unit condenses light emitted from a light source to form a condensed spot on a color wheel. The shading unit, when a size of the condensed spot on the color wheel has increased due to an increase in light emission of the light source, shades a portion of the light passing through the color wheel corresponding to the increased size.
