Abstract: PURPOSE:To enable an operator to easily conduct the suction of cutform paper and get the discharged cutform paper in hand as the operator remains positioned before a printer, by a method wherein, a take-out part is inclined downwards from the lower part thereof to the forward of the printer, and the cutform paper is moved by falling under its own weight as it is taken out. CONSTITUTION:The power of a motor 1 rotates an upper roller 3 through a belt 2. A paper feed roller 4 rotates together with the roller 3 to feed cutform paper 7. When the paper 7 is separated from the roller 3 and the roller 4, the paper 7 is put into a take-out part 5 and falls down by gravity. Then, a fall guide part 6 receives the paper 7, and the paper 7 falls downwards along the fall guide part 6. At this time, the paper 7 is disposed the same side up as it is discharged from a printer 8, and only the movement of the paper 7 is reversed from upward movement to downward movement. Therefore, the paper 7 reaches a stacker part 11 as it is discharged from the printer 8. Moreover, because the stacker part 11 is disposed near an operator, the operator can easily take the paper 7 out of the stacker part 11.

Abstract: PURPOSE:To prevent temperature from rising above a prescribed value owing to the defect or malfunction of a thermistor by comparing the quantity of a temperature rise from a power-on point with a point which is a specific time later with a preset stored value. CONSTITUTION:When the temperature detected by temperature detecting means 7 and 8 at the time of the power-on point of a power source 2 is lower than specific temperature, the surface temperature of a fixing roller 5 is detected by the temperature detecting means 7 and 8 the specific time after the power source 2 is turned on, and the effective value of the power source at the time of the power-on point of the power source 2 is detected; and the temperature rise from the power-on point of the power source 2 to the point which is the specific time later is compared with the upper-limit value of a temperature rise quantity corresponding to the specific time which is set and stored corresponding to the voltage of the power source 2. Then when the temperature rise is not within the range between the upper-limit value and lower-limit value which are stored in advance, it is considered that abnormality occurs and a fixing heater 5 is prevented from being driven. Consequently, the fixing roller 5 is prevented from rising in temperature more than necessary owing to misdetection due to the defect of the temperature detecting thermistor 7 of the fixing roller 5 or its fitting defect.

IPC: H01L21/3213
Filed: 1994-06-10
Abstract: PURPOSE:To provide a plasma etching device and method with which a connection hole can be buried in an excellently flat manner by etching back a blanket CVD tungsten layer. CONSTITUTION:A conductive thin film 6, consisting of a blanket, is formed on the whole surface of the substrate to be etched including a connection hole 4. When an etching treatment is conducted on the film 6, first, film thickness is computed by measuring sheet resistance, and the time for starting of end-point judgement by monitoring the intensity of emission spectrum, is det ermined based on the value of film thickness.
