摘要:
A color display apparatus for a video information system includes an input for receiving at least one externally applied color component signal, a display device having predetermined color characteristics, and a compensating unit responsive to the at least one externally applied color component signal from the input for compensating at least a portion of the at least one externally applied color component signal in accordance with the predetermined color characteristics of the display device. The display device is responsive to the input and the compensating unit for displaying a color image of the externally applied color component signal.

A light emitted from a laser diode is reflected by a video disc which is rotated by a spindle motor. The reflected light is modulated by video information recorded on the video disc and converted to an electrical signal by a photodiode array. A signal generated by a trapezoidal generator is sampled with a horizontal synchronizing signal separated from the video information signal. The sampled signal is supplied to the spindle motor for correcting a time base error. A zero crossing point of the trapezoidal waveform is detected and is utilized for controlling the start of a rise portion of the trapezoidal waveform for compensating a DC offset. The trapezoidal waveform is controlled so as to vary an average power supplied to the spindle motor in accordance with a detected rotational speed difference so as to compensate a rotational speed of the spindle motor.

There is provided the construction of a multiprojection apparatus composed of a plurality of projection units arranged in the vertical and horizontal directions, in which a transparent holding strip having an H-shaped cross section is inserted between screens each composed of a lenticular sheet and a Fresnel lens, and the right and left ends of a multiscreen are supported by elastic support members, or in which a receive member for receiving the screen in the direction of the optical axis and a screen holding device are provided, the receive member has such a shape as not to block projection light corresponding to an image on the screen and is located near a joint of the screen and another screen, and the holding device is disposed on a black stripe of the lenticular sheet and always pulled by an elastic member toward the receive member. Therefore, according to the present invention, it is possible to restrict the missing of information due to joints of the screens.

An accessory making device (1) of the present invention is a device for making an accessory including a core (83) formed into a substantially ring shape by connecting both ends of a stretchable cord-like body (46) having rubber-like elasticity and a decoration main body (83) disposed around the core in such a manner so as to abut both ends thereof against each other in a contracted state so as to be reduced in axial length. The accessory making device (1) includes a long rigid holder (5). The holder (5) can retain connecting portions (47M, 47F) on both end sides of the cord-like body (46) with the connecting portions (47M, 47F) of the cord-like body (46) separated from each other, and can be inserted through the decoration main body (83).
摘要:
On a support, a porous resin layer which is opaque in a water-unabsorbed state and capable of turning transparent in a water-absorbed state is formed, and also a water-repellent resin layer is so provided as to exist in the porous resin layer at its some area or areas in a co-existent state, to make up a water-metachromatic laminate. A novel toy element can be provided in which latent images standing invisible in a normal condition are rendered visible by means of water as a medium so as to be visually distinguished.

A water-metachromatic sheet has a support with a porous layer containing a binder resin with dispersed fine-particle silicic acid. The sheet is capable of rendering different transparency between water absorbed and unabsorbed states. The support is a cloth having a weight per unit area of 30 gm2 to 1,000 gm2, the fine-particle silicic acid is contained in an amount of from 1 gm2 to 30 gm2, and the fine-particle silicic acid is incorporated in an amount from 0.5 to 2 parts by weight based on 1 part by weight of the binder resin.
摘要:
A color-change laminate in which a color tone derived from a porous layer is visually perceived in a dry state and a metallic lustrous property is visually perceived in a liquid-absorbed state of the porous layer caused by water application is excellent in luminance and which satisfies both of changing properties and decorative properties in the dry state and in the liquid-absorbed state. A color-change laminate includes a support having a metallic lustrous property and a porous layer provided on the surface of the support. The porous layer includes a low-refractive-index pigment and a transparent metallic lustrous pigment formed by coating a transparent core material with a metal oxide and/or a transparent metallic lustrous pigment having a color-flopping property all fixed onto a binder resin in a dispersed state and is different in transparency in a liquid-absorbed state and in a liquid-unabsorbed state.

An drawing toy 1 having a excellent performance in play to which water is applied to form images such as letters or characters, and patterns or designs, which are perceivable as images having brilliance is constituted of an drawable member 2 having a light-transmitting support 3 and provided on the surface thereof a porous layer 4 in which a low refractive index pigment has been made dispersedly fixed to a binder resin and which comes different in transparency between a liquid-absorbed condition and a liquid-non-absorbed condition, and a light source 5 which irradiates the back surface of the drawable member with light. A drawing toy set is constituted of the drawing toy 1 and a water-applying implement 15.
摘要:
To provide: a water-discoloring drawing toy which, when a writing utensil or applicator for water adhesion is applied thereto, produces a multicolor image and which eliminates the monotonous production of monochromatic images in a related-art technique and is rich in unexpectedness and changes; and a water-discoloring drawing toy set including this drawing toy.A water-discoloring drawing toy 1 having such a constitution that a drawing made by applying a writing utensil or applicator for water adhesion produces a multicolor image, the drawing toy comprising: a substrate; many non-discoloring images differing in color tone and adjoining each other disposed on the substrate so that at least two color tones per 100 cm2 can be visually recognized in the part having the non-discoloring images; and a porous layer for preventing the non-discoloring images from being seen in the ordinary state, the porous layer being disposed over the non-discoloring images and comprising a binder resin and a low-refractive-index pigment fixed therein in a dispersed state, the porous layer having a difference in transparency between a liquid-impregnated state and an unimpregnated state. Also provided is a water-discoloring drawing toy set which comprises the water-discoloring drawing toy 1 and a writing utensil 3 or applicator for water adhesion.
