摘要:
Supported catalysts for hydrotreating hydrocarbons comprise (a) at least one member selected from the group consisting of oxides of metals in Groups IV and VIII of the Periodic Table, and (b) at least one organic compound having a mercapto radical or radicals (--SH) selected from the group consisting of mercapto-carboxylic acids, including alkali metal, alkaline earth metal and ammonium salts thereof and esters thereof, bivalent mercaptans, amino-substituted mercaptans, and thiocarboxylic acids. These catalysts can be easily activated by treatment in the presence of hydrogen gas at a temperature in the range from room temperature to 400.degree. C. show higher activity than catalysts activated by conventional methods.

According to one embodiment, a printing device includes a conveyance mechanism configured to convey a printing medium along a conveying path, and a detection device provided on the conveying path and configured to detect a position of the printing medium therealong. The printing device further includes a control device configured to select one of first and second conveyance modes in response to a predetermined condition, the control device being further configured to control the conveyance mechanism so as to convey the printing medium along the conveying path based on the selected conveyance mode. In the second conveyance mode, the printing medium is conveyed along the conveying path while being detected by the detection device, at a conveyance speed slower than that of the first conveyance mode.

In a printing apparatus, a dot head moves along a movement path which is orthogonal to a conveyance direction of a passbook, one end side of the head movement path is a speed-up area, a halfway part is a constant speed printing area, and the other end side is a slow-down area. A thermal head is disposed in a direction orthogonal to a conveyance direction of a thermal sheet, and a width size in the orthogonal direction is not smaller than the printing area of the dot head.

In a state where a sheet exists, an current I is gradually increased. When an voltage V reaches a light receiving level Vx, the current I at the time is stored as I1. The voltage V immediately before the voltage V reaches the light receiving level Vx is stored as V1. In a state where no sheet exists, the current I is gradually decreased from the above I1. When the voltage V reaches a non-light receiving level Vy, the current I at the time is stored as I2. The voltage V immediately before the voltage V reaches the non-light receiving level Vy is stored as V2. Then, the current I at the time of normal operation is set within a range between I1 and I2. A reference voltage Vs is set within a range between V1 and V2.
