IPC: G03G21/00
Filed: 1994-08-12
Abstract: PURPOSE: To provide a cleaner to use a spot stirring blade having low friction, low elasticity and high hardness. CONSTITUTION: A spot blade assembly 230 is provided with a holder 225 and a spot stirring blade 220. In order to stir residual particles which are not removed by a 1st cleaner brush 100, the spot blade assembly 230 is arranged on the downstream side in a moving direction 12 of a receptor 10. The blade 220 accumulates the residual particles on its front. The accumulated residual particles are removed by vacuum air flow. A spot blade material provides contact to be continuously slid between the spot 220 and the photodetector surface by combining the mechanical characteristics of low friction, low elasticity and high hardness. Thus, the bound or skip action of the blade is decreased, the quality of copy is improved and the service life of the blade is prolonged.

Title: Welding method of sodium piping
Inventor: FUJITA MASAO
IPC: B23K31/00
Filed: 1982-11-04
Abstract: PURPOSE:To obtain a good weld zone which is free from intrusion of Na by disposing cooling parts which adsorb Na vapor contained in the inert gas in a pipe and prevent the evaporation of Na owing to welding heat at the front and rear of the weld zone and performing welding. CONSTITUTION:Cooling parts 5 for piping, for example, wet waste cloths 6 or objects that permit passage of cooling gas or the like therein are installed near a weld zone 8, after the internal treatment of a pipe 1 with Na. The temp. in said parts 5 is monitored with thermometers 7 so that said temp. is maintained always at an ordinary temp. or below. The inside of the pipe 1 is then replaced with inert gas and welding is started. The Na vapor 4 contained in said gas is stuck to the parts 5 and at the same time, the temp. elevation of the pipe 1 owing to welding heat is suppressed by the cooling effect of the parts 5, whereby the evaporation of the Na remaining in the pipe 1 is prevented. The welding is thus accomplished without intrusion of the Na vapor into the weld zone 8 and the quality of the weld zone is improved.
