A wavelength conversion laser light source includes: a non-linear optical crystal of an oxygen octahedral structure, having added thereto a metal ion in other components than a main component; a light source for projecting light into the non-linear optical crystal in an operation mode; and a refractive index recovery mechanism for carrying out a recovery operation for recovering a refractive index of said non-linear optical crystal as shifted overtime due to light projected into the non-linear optical crystal in the operation mode with an applied external energy into the non-linear optical crystal in a non-operation mode in which light is not injected to the non-linear optical crystal.

In a picture tube device with a field-emission cold cathode, including a plurality of electron-emitting cathodes, and a lead electrode provided with a plurality of apertures surrounding the plurality of electron-emitting cathodes respectively, a surface of the lead electrode has a curved shape that is convex in an electron emission direction. This makes it possible to obtain a high-resolution and high-performance picture tube device that has an excellent focus performance over an entire beam current.

A CRT device with an electron gun provided therein includes control means for controlling voltages applied to a cathode and a control electrode constituting the electron gun. The control means exerts control on each electrode voltage so that the difference between the cutoff voltage of the cathode and the voltage of the control electrode is greater when the luminance level of a luminance signal separated from picture signal is higher, thereby minimizing a spot diameter.

In a paper sheet dispensing apparatus according to the present invention, horizontally stacked bills are removed by a dispensing roller through a dispensing port one by one. When the dispensing operation is completed, one end of the stack of bills which is located furthest away from the dispensing port is held by an upper flapper, and the stack is moved by a predetermined distance in a stacking direction away from the position of the dispensing roller as the upper flapper moves. Thereafter, the upper flapper from the stack of bills is released, and the stack is moved toward the dispensing roller by an urging force of a spring and is brought into contact with the dispensing roller.

Disclosed is an apparatus for selectively turning the pages of a book forward and backward. The apparatus of the present invention comprises a roller, first transfer means, pressing means, driving means, and second transfer means. The roller can rotate selectively in one and the other rotating directions. The first transfer means selectively transfers the roller between first and second positions. The pressing means presses the book against the roller. The driving means drives the roller to rotate selectively in the one and the other rotating directions. The second transfer means moves the book so that one page of the book lifted by the roller is laid on top of the other page. In such construction, the pages of the book can be turned selectively in the forward and backward directions by means of the single roller.

A cathode structure comprises a cylindrical metal sleeve having aperture portions at both ends, a base metal having an aperture portion on one end, which is fitted onto one of the aperture portions of the metal sleeve, and an electron-emitting layer, which is formed on a flat portion of an outside surface of the base metal. After an electron-emitting material is sprayed onto the base metal, its surface is mechanically flattened to form the electron-emitting layer. Thus, the planarity of the surface of the electron-emitting layer can be improved without deterioration of the electron emission characteristics and the moiré can be decreased without reduction of the resolution.

A bank note handling system includes a cabinet, a removable bank note cassette in the cabinet for storing a supply of bank notes, the supply of bank notes including notes having a desired denomination and being subject to the inclusion of notes having undesired denominations, the bank note cassette including a memory for storing denomination data corresponding to the desired denomination of the supply of bank notes. In the cabinet, a controller for reading the denomination data from the memory, a feeding mechanism for removing the bank notes from the bank note cassette, and a discrimination unit for discriminating the denomination of each bank note removed from the bank note cassette are arranged. The controller acts to compare the denomination discriminated by the discrimination unit with the denomination data read from the memory for detecting the presence of notes having an undesired denomination.

An electron emitting element includes a vacuum container 3, electron sources that emit an electron beam, and a power supply structure 4 that supplies a voltage to the electron sources. The electron sources are formed on a silicon substrate 21. The power supply structure 4 is disposed outside the vacuum container 3.

When the thickness of the panel at an X axis end of the useful portion is expressed by Tx (mm), the thickness thereof at a Y axis end is expressed by Ty (mm), the thickness thereof at the center is expressed by Tc (mm) and an outer dimension of the panel along the diagonal axis direction is expressed by D (mm), 0.8≦(100×Tc/D)2×(Tx/Ty)≦2.2 and 0.012≦Tc/D≦0.019 are satisfied. Accordingly, the stress generated in a short side and that generated in a long side in a sealing portion in an exhausting process are substantially equalized. As a result, cracking of the panel can be reduced in the exhausting process even when the panel is made thinner. Therefore, it is possible to provide a cathode ray tube that is easy to manufacture and has a lighter and less expensive panel.
