Abstract: A recording apparatus includes a panel that supports an outer periphery of a display which displays various information; and a cover which is made of a resin material and is detachably mounted on the panel so as to cover the display in a state being mounted on the panel, wherein the cover includes a thin-wall portion and an inclined portion which serve as an outer area disposed along the outer periphery and a thick-wall portion which serves as an inner area disposed inside the outer area with the thickness of the outer area being smaller than the thickness of the inner area.

Abstract: A roller for transporting a recording medium includes an inner layer having a shaft hole through which a rotating shaft passes; and an outer layer formed outside the inner layer and brought into contact with the recording medium. At least a first end surface of the inner layer in a direction along the rotating shaft is located inside the outer layer remote from end surfaces of the outer layer in the direction along the rotating shaft.

Abstract: Certain 3-piperidino fluoran derivatives useful as color recording materials are disclosed.

Abstract: An apparatus for measuring neutrons and gamma rays is disclosed in which after pulses generated by neutrons are discriminated from pulses generated by gamma rays, two different counted values are obtained for either the pulses generated by neutrons or the pulses generated by gamma rays to control a discriminating circuit between the pulses by neutrons and the pulses by gamma rays so that a ratio between the different counted values is kept constant, and further two different counted values are obtained for either the pulses by neutrons or the pulses by gamma rays in a manner the same as the above-mentioned to control the output of a detector so that a ratio between the counted values is kept constant.

Abstract: Certain 3-substituted amino-7-substituted fluoran derivatives useful as color recording materials.

Abstract: A bulk material of grain, lump or any other form is irradiated with neutron and gamma radiation emitted from preferably a single radiation source, and preferably a single radiation detector detects the neutrons and gamma radiation transmitted through the bulk material, so that the moisture content of the bulk material can be accurately measured without being affected by the bulk density of the bulk material.

Abstract: A recording material which is suitable as a pressure-sensitive or heat-sensitive copying paper or recording paper by developing a color in contact with an electron-accepting material which comprises certain fluoran derivatives containing piperidino, pyrrolidino, morpholino and cycohexylamino groups.
