Title: Inspecting method for heat pipe
Inventor: MASUKO KOICHI
IPC: G01M3/28
Filed: 1988-05-16
Abstract: PURPOSE:To easily and securely inspect whether or not the heat pipe is normal by setting the pressure in a vacuum container where the heat pipe is installed to pressure lower than the vapor pressure of working liquid and measuring a rise in the pressure in the container. CONSTITUTION:The heat pipe 10 where the working liquid is charged in an enclosed container is installed in a vacuum container 11 and sealed. Then a vacuum pump 13 lowers the pressure in the container 11 to vacuum pressure and then the pressure in the container 11 is lower than the vapor pressure of the liquid. There is no variation in the pressure in the container 11 unless the pipe 10 has a defect in airtightness such as a pinhole. If, however, the pipe 10 has the pinhole, the liquid in the pipe 10 leaks in the container 11 and the amount of gas increases, so that the pressure in the container 11 rises. This pressure variation is measured by a manometer 14. Consequently, whether or not the heat pipe is normal is easily and securely inspected.

Title: Reversal bias developing method
Inventor: MASUMURA MASAO
IPC: G03G13/08
Filed: 1978-09-28
Abstract: PURPOSE:To prevent deposition of toner on non-image portions by changing over the bias voltage of a developing sleeve in timing to the time when the specified position on the surface of a photosensitive drum opposes to the developing sleeve thereby cutting the application of the voltage or lowering the same. CONSTITUTION:Application of bias voltage to a developing sleeve 3 is accomplished at the time when the position on the surface of a photosensitive drum 1 which is within the charging region of the surface of the drum and does not enter the image region of the photosensitive drum 1 surface arrives at the position oppositing to the developing sleeve 3. On the other hand, changing-over of the developing bias voltage to the OFF state is accomplished at the time when the surface position of the drum 1 opposing to the developing roller 3 is within the charging region after passage of the end part of the image region. Operation in this way reduces the range of the non-image portions where the developing bias voltage is being applied and reduces the pickup of the toner on the non-image parts.
