摘要:
The present invention concerning the Optical Identification Card System is provided with an individual card which emits infrared light modulated by the individual code and a detector which receives this infrared modulated light and detects the individual code. When a request signal is radiated from this detector as infrared light from the above within the prescribed light-emitting area, the said infrared modulated light is radiated from the individual card within the light-emitting area and thus the individual code is detected by the detector. Then the detected individual code is identified by the identifier, and on the basis of this identification result, the terminal equipment related to the holder of the individual card is actuated, thereby automatically locking and unlocking the door.

LED chip 40 is supported by being held inside concave part 23 in one lead 21 at this time.
摘要:
A decoloring type heat sensitive image recording material comprises a transparent support and a heat sensitive layer provided thereon. The heat sensitive layer contains color particles and a hydrophilic binder. The color particles are dispersed in the hydrophilic binder. The color particles are formed by a reaction of a leuco dye with a phenol developer. The heat sensitive layer substantially does not contain particles of a decoloring agent. The heat sensitive layer can be decolored in such a manner that a thermal energy applied to the image recording material causes a reaction of the color particles with the hydrophilic binder to decolor the particles, and that the decolored state is kept at room temperature. A process of recording an image by decoloring the heat sensitive material is also disclosed.

A process for the preparation of light-sensitive microcapsules comprises encapsuling silver halide and a polymerizable compound with a shell comprising an aminoaldehyde resin in an aqueous medium in the presence of an anionic protective colloid, wherein the anionic protective colloid is a mixture of pectin and a polymer comprising a repeating unit derived from styrenesulfonic acid such as poly(styrenesulfonic acid) and a copolymer of an ethylenic unsaturated compound and styrenesulfonic acid.
摘要:
A cooling device for a vehicle has a heat exchanger, a duct that forms a passage for air that has passed through the heat exchanger, and a cross-flow fan provided within the duct. The fan draws in the air that has passed through the heat exchanger and blows it out from the duct. The fan is placed outside of a horizontal projection area from the vehicle front to the vehicle rear of the heat exchanger. The duct has an opening portion that opens when the vehicle is at a predetermined speed or more so that the air that has passed through the heat exchanger when the vehicle is at the predetermined speed or more passes through the opening portion without passing through the fan.
摘要:
A light-sensitive microcapsule contains silver halide, a reducing agent, an ethylenically unsaturated polymerizable compound and a color image forming substance. Another light-sensitive microcapsule contains a photopolymerization initiator, an ethylenically unsaturated polymerizable compound and a color image forming substance. The microcapsules are prepared by a process comprising the steps of emulsifying an oily phase containing the silver halide, the reducing agent, the polymerizable compound and the color image forming substance (or an oily phase containing the photopolymerization initiator, the polymerizable compound and the color image forming substance) in an aqueous medium containing a water-soluble polymer in water; and forming the shell around the droplets of the oily phase. In the process of the present invention, the oily phase is emulsified in the aqueous medium by mixing the oily phase and the aqueous medium; supplying the mixture to a clearance of not larger than 5 mm between an inner cylinder and an outer cylinder; passing the mixture through the clearance while rotating the outer cylinder and/or the inner cylinder. Light-sensitive materials prepared by using the light-sensitive microcapsules are also disclosed.
