Title: Developer supplying method, and developing device and image forming device, using the method
IPC: G03G15/08
Filed: 1992-05-15
Abstract: PURPOSE:To prevent reduction in a concentration even when the ratio of an image is different by replenishing the specific amounts of developer, according to the output signal of a developer quantity detecter, and then, intermittently suspending replenishment for a specified time without depending on the output signal. CONSTITUTION:A developer replenishment controller replenishes the developer of a quantity based on the signal, to a developer carrying part formed along the longitudinal direction of a developer vessel from a developer supplying vessel. At this time, time for continuing the drive of a hopper is set two seconds, without depending on the ratio of the image of an original. Therefore, even when the ratio of the image of the original is low, toner is set so as to accumulate high. On the other hand, even when the ratio of the image is high, the ON time of a hopper driving signal is set two seconds, so that the toner is set so as to accumulate low. After the ON time of the hopper, the pausing time of one second is certainly set regardless of a toner sensor detecting signal, and the developer is intermittently replenished with a specified pausing time held.

Abstract: PURPOSE:To decrease the generation of a fault by deciding in which direction a temperature detected value is varied, and in which area said value exists, at the time of variation of a load capacity, and executing ON/OFF operations before an operation at the time of a stationary load. CONSTITUTION:A temperature controller brings a final control element 15 to ON/OFF operations, based on an output of a temperature detector 14 in order to allow a steel plate 11 to be brought to a surface treatment, to pass through in a solution 13 in a treatment tank 12 and to execute stably the surface treatment of the steel plate, and controls said solution 13 to a prescribed temperature. In this case, a detected value PV of the temperature detector 14 is supplied to not only a deviation calculating part 17 but also a difference calculating part 18, and a variation rate signal is derived and supplied to lower limit/upper limit variation rate direction deciding circuits 19, 20. Subsequently, when its has exceeded the lower and the upper limits, a conditional signal for bringing the final control element 15 to ON/OFF operations is outputted. This signal is sent to negative/positive area deciding circuits 21-22, and when it is decided that the condition has been formed, said signal is set to a holding memory 27 from OR circuits 25-26. In such a way, a temperature can be controlled appropriately in spite of a change of a load capacity.

Abstract: PROBLEM TO BE SOLVED: To specify heat generating spots in detail in the course of infrared inspections which are performed for detecting defective heat generating spots in a semiconductor device. SOLUTION: A heat generating picture microscope uses a probe 1 having an optical fiber 16 which takes in infrared rays generated by heat generation at its center. The front end of the fiber 16 is more recessed inward than the front end of the probe 1 and the side wall of the recessed section is coated with an infrared-ray absorbing film 17.

Filed: 1989-06-12
Abstract: PURPOSE:To prevent transmission data from an opposite station dissipated by prohibiting a recording operation with a thermal head when an outside air temperature is very low and recording quality is remarkably deteriorated. CONSTITUTION:A CPU 1 fetches the outside air temperature measured with an outside air temperature sensor 22 periodically via temperature detection circuits 25 and 23 for head temperature detection, and prohibits a data reception operation when the outside air temperature is outside the range of recording operation guarantee temperature set in advance. Therefore, by setting the range of recording operation guarantee temperature at a temperature range where constant recording quality can be held even under energy control only by a head temperature, no data reception operation is performed and reception abnormality is informed to a transmission side when the outside air temperature goes down to a very low temperature and no print with sufficient density is performed. In such a way, it is possible to prevent unsharp recording performed and the transmission data dissipated.
