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.

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.

A printer includes: a USB connector that is detachably connected to a USB interface forming a data communication channel through which data can be exchanged between the printer and an external device; a second connector that is constantly connected to a second interface that is provided independently of the USB interface and forms a data communication channel through which data can be exchanged between the printer and the external device; a USB connection detection section that detects whether the USB interface is connected to the USB connector; a signal channel selection section that receives a switch control signal from the USB connection detection section and switches a data communication channel from the data communication channel using the second interface through which data is exchanged between the printer and external device to a data communication channel using the USB interface; a signal conversion section that is provided between the signal channel selection section and second connector and coverts USB data signal into a data signal for the second interface and vice versa; and a USB controller that controls USB connection.
摘要:
The present invention detects print data areas set in one-block units with white lines as boundaries, calculates division numbers for divisionally driving a line head every areas extending in its main scan direction to thereby output print data when the numbers of dots set every lines in the print data areas exceed the maximum number of printable dots set by a head drive unit, detects maximum division numbers n in the print data areas, sets paper feed velocities V1 through V4 in inverse proportion to the maximum division numbers n respectively, and executes printing in the print data areas set in the one-block units on the condition that the line head is divisionally driven with the maximum division numbers n and paper is fed at the set paper feed velocities V1 through V4. Thus, a reduction in power consumption can be satisfied. Since it is possible to increase a paper feed velocity in proportion as a print data area low in the number of dots in particular, the speeding up of printing can be achieved.

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.
摘要:
A medium processing apparatus which corrects the tilt of a medium is provided. The medium processing apparatus according to one embodiment of the present disclosure includes a conveyer configured to convey a medium along a conveying path, and a shutter located along the conveying path to block the conveyance of the medium. The medium processing apparatus further includes a detector configured to detect a tilt of the medium with respect to the shutter, and a shutter controller configured to control the shutter to unblock the conveyance of the medium when the detector determines that the tilt of the medium is corrected.

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.
