An authenticity discriminable printed matter in which a latent image cannot be visually identified under ordinary visible light but appears upon being irradiated with UV rays. A basic image is formed on a base material. The basic image is made of a latent image portion and latent image peripheral portion. The latent image portion and latent image peripheral portion cannot be visually discriminated, and each of them is formed from a set of dots continuously laid out at a predetermined period. The resolution of the dots of the latent image portion is different from that of the dots of the latent image peripheral portion. The latent image portion and latent image peripheral portion have the same percent dot area per unit area and different dot peripheral lengths (contour lengths) per unit area. The latent image portion and latent image peripheral portion are printed by color fluorescent ink, thus obtaining printed matter.

A method and mechanism for selectively transmitting and interrupting power between an input shaft and an output shaft arranged in coaxial relation in which a rotary member is coupled to one of the shafts to provide first and second states therebetween and wherein in the first state the rotary member is free to rotate and rotation is transmitted between the input and output shafts, whereas in the second state the input shaft can rotate relative to the output shaft and transmission of rotation is interrupted. The rotary member and the one shaft are angularly rotated relative to one another between first and second relative positions in the first and second states, and rotation of the rotary member is halted by a disc brake in the second state.

A process for preparing ground resin particles is provided by modifying a jet mill with opposed fluidized bed. By using a jet mill having a plurality of jet nozzles disposed at predetermined positions in a barrel of a grinding chamber toward the injection point of the grinding chamber and a bottom wall having a flat surface in part or in whole, parallel to the jet nozzles, or having a conical projection immediately below the injection point, resin particles to be ground are jetted with or without water, thereby being ground to obtain ground resin particles of an intended particle size.

摘要:
To the end of eliminating the problems arising from substantially rigid connection between a front wheel set and a rear wheel set in a four-wheel drive vehicle, there is provided a power transmission system in which a speed-dependent power transmission device is provided between the front wheel set and the rear wheel set so that both the wheel sets are substantially rigidly connected to each other in a low speed range and rotational power is transmitted only from the front wheel set to the rear wheel set in a high speed range. The power transmission device of this kind can be conveniently formed by a pair of one-way clutch elements which are connected between an input member and an output member in a mutually parallel relationship; one of the one-way clutch elements transmitting power from the input member to the output member in both the high and the low speed range while the other one-way clutch element transmits power only from the output member to the input member in the low speed range but does not transmit power in either direction in the high speed range. This speed-dependency can be accomplished by using one-way clutch sprag elements each having a gravitational center offset from its center of rolling motion for wedging between the input member and the output member.
