Title: Photoconductive material for infrared ray
Inventor: MATSUMOTO MASAKAZU
IPC: G03G5/06
Filed: 1985-08-20
Abstract: PURPOSE:To obtain an electrophotographic sensitive body having superior durability and potential stability as well as high and flat sensitivity in the infrared wavelength range of semiconductor laser or the like by using a specified disazo pigment. CONSTITUTION:A disazo pigment represented by the structural formula (where R is an electron donative group and A is aryl or a heterocyclic group having nitro, cyano or trifluoromethyl) is used in the charge generating layer of an electrophotographic sensitive body, especially a separated function type sensitive body. When R in the formula is -OCH3 and A is phenyl having one or more nitro groups, the photosensitive wavelength range of the pigment represented by the formula exceeds 790nm and the pigment produces the most significant effect as a photoconductive material for infrared rays. The pigment has high sensitivity, this sensitivity is flat even in a longer wavelength range, and the pigment also has superior durability and potential stability. The pigment can be advantageously used in the photosensitive layer of an electrophotographic sensitive body using semiconductor laser as a light source or a sensitive body for a laser beam printer.

Abstract: PROBLEM TO BE SOLVED: To improve the performance of an adjustment mechanism and to improve the productivity and workability of maintenance and inspection and operability by freely movably disposing an operation device for structure body turning adjustment extendable and contractable within a prescribed stroke between the ground and the structure. SOLUTION: The operation device 34 is composed of two jacks 36 and 37 for the structure turning adjustment extendable and contractable within the prescribed stroke and is freely movably disposed between a ground surface E and the structure 22.

Abstract: PROBLEM TO BE SOLVED: To surely receive a communication result by specifying replenishment with a recording medium and/or outputting or erasing data stored on a recording medium when the rest of the recording medium is less than a specific amount at repeated broadcasting of transmission or transfer transmission, using a subaddress signal. SOLUTION: A control circuit 20 decides whether or not origination is selected and then decides whether or not there is a termination choice. When origination is selected, information of signal lines 24a and 26a is inputted to decide whether or not a specific subaddress code (F code) of repeated broadcasting transmission is inputted. When an affirmative answer is obtained, information of signal line 16a is inputted and it is decided whether or not there is recording paper. When there is no recording paper, the capacity of a usable memory is confirmed, and when specific capacity is available, transfer transmission is performed. However, when a negative answer is obtained, a return to the start process is made to repeat the same processes.  When a deficiency in the rest of the recording medium is specified, replenishment with a recording medium and the output or erasure of the data stored on the recording medium can be performed.
