Title: Overvoltage protective circuit for chopper device
Inventor: MASAKI HISAMITSU
IPC: H02M3/155
Filed: 1981-12-18
Abstract: PURPOSE:To accurately perform the overvoltage protection for the titled chopper device using a simple constitution by a method wherein a thyristor for fuse cutting is combinedly used as an energy releasing circuit. CONSTITUTION:When a transistor is brought into an uncontrollable state and over-voltage is generated, a turn-ON signal is outputted to a thyristor 12 at the moment when said overvoltage exceedes the overvoltage detecting value of an output voltage detecting circuit 7. As a result, the thyristor 12 is turned ON, the short-circuiting circuit of a three-phase bridge circuit 1 is formed, and a fuse 11 is fused-cut by the excessive current. At the same time, the accumulated energy on a smoothing circuit is discharged to the circuits of the thyristor 12 and a diode 14, and the voltage applied to load 3 drops suddenly, thereby enabling to accurately perform the protection for the load 3.

Filed: 1994-08-30
Abstract: PURPOSE: To unnecessitate a temperature sensor and to prevent noise from being produced by judging the-rise of temperature on the table glass of an original platen and decreasing copying speed. CONSTITUTION: By turning on a power source, timer routine is N started. Whether a copying mode is an OC mode(document setting method by which a user sets documents 4 on the table glass 10 one by one by wholly lifting an SPF(single paper feeder) 1) or an SPF mode is detected. When it is the OC mode, copying is performed at ordinary copying speed. On the other hand, in the case of detecting the SPF mode, the number of documents is counted. When the number of documents exceeds specified number, the copying speed is decreased, and when it is equal to or under the specified number, the copying is performed at the ordinary copying speed. Whenever a timer counts the specified time, counting is reset by the timer routine. Furthermore, the counted number of documents is reset by main routine.

Title: Cooling and heat exhausting device for copying machine
Inventor: KIMURA AKIYOSHI
IPC: G03G15/18
Filed: 1981-12-22
Abstract: PURPOSE:To prevent the scattering of toners, by providing heat pipes containing a heat medium liquid at the places near various types of heat sources to absorb the heat from the circumference owing to the evaporation of the heat medium liquid as well as to collect the saturated steam of the heat medium liquid of each heat pipe at an area to dissipate the heat. CONSTITUTION:The heat pipes 10 containing the heat medium liquid are provided near various types of heat sources within a copying machine. When heat absorbing parts 10a and 10b are heated by the heat radiated from an illumination lamp 4 and fixing heat rollers 6 and 6', the heat medium liquid within the heat pipes are evaporated to absorb a large quantity of heat of evaporation. The saturated steam of the heat medium liquid generated in such a way reaches a collecting part 10c to dissipate the heat and then liquefied again. Thus the heat generated at an illuminating part and a fixing part is collected at an area by means of the heat pipes and then exhausted concentrically. This process prevents perfectly the scattering of the powder toner, and at the same time a complicated construction can be eliminated for the titled device as a whole.
