Filed: 1993-05-07
Abstract: PURPOSE:To finely control an individual casting device according to the impairment condition. CONSTITUTION:A controller for controlling a line connected with a personal computer at the terminal of a network for casting gives an operation command to the individual casting device in the casting line to operate the casting line (A, B). In the individual device, the operating timings, such as limit switch, solenoid, motor, arranged to the various positional detecting place, are detected electrically and inputted into the personal computer in the casting line (C). This personal computer compares the operation command and the operation detection (D), and an error in time (troubling time) of the operation detection to the operation command and this number of times are counted (E). The personal computer displays the troubling time and this number of times in the individual device and automatically makes a table for trouble history displaying the degree of malcondition (alarm sign) deduced from these data (F). This table for trouble history is served to a process control and a quality control (G).

Title: Control device for copying machine
Inventor: KANETANI KOICHI
IPC: G03G15/00
Filed: 1986-05-12
Abstract: PURPOSE:To grasp easily where paper jam is liable to occur and carry out pertinent treatment by counting the number of paper jams per each unit under operation and saving the number in non-volatile memory. CONSTITUTION:A paper jam is judged to have occurred when paper has stagnated at a jam sensor 1 for more than a predetermined time, and (+1) is added to the value of an 8000H address in RAM26, thereby storing one occurrence of paper jam at the paper feed part. This RAM26 can save the contents of memory even when a power source is turned 'OFF' and, therefore, a total number of jams is saved through accumulation per each unit after grounding a machine. Then, when a service engineer has come to the machine for periodical inspection, he inputs a signal into the address of RAM26 from a key board including the numerical keys thereof, thereby knowing the number of the occurrences of jams and judging whether the number is large or small for the working hours of the machine. And when the number is large, a component related to the jams is considered to the giving a trouble and inspection concentrated thereupon can be carried out.

Title: Control circuit of laser module
Inventor: ITO TORU
IPC: H01S5/0683
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To prevent voltage drop due to a resistor for current detection and enable low voltage driving, by installing a current feedback circuit which controls the output light of a laser diode to be constant by the output signal from a monitor photodiode. SOLUTION: When a PD-S feedback voltage decreases, the output of an operational amplifier OP3 32 decreases, and the base-emitter voltage of a transistor Q3 34 decreases, so that the current value of a laser diode LD1 35 decreases and a pumping light Ppump decreases. A back monitor photodiode 36 monitors the output of the laser diode LD1 35, converts the output to a current, and converts it to a voltage V4 with a variable resistor RV1 37. When the output of the laser diode LD1 35 decreases, the voltage V4 decreases and the output of an operational amplifier OP4 39 also decreases. As a result, it is unnecessary to connect a resistor for current detection in series with the laser diode LD, so that the voltage drop due to a resistor R1 for current detection is avoided and low voltage driving is enabled.
