Title: Adhered substance removing device for vehicle window
Inventor: KUMAMOTO HITOSHI
IPC: B60S1/54
Filed: 1989-05-15
Abstract: PURPOSE:To ensure the visual field of a window in a constantly excellent state despite of a weather state by a method wherein compressed air generated through the working of a compressor is blown through a compressed air discharge port against the front of the window to blow off an adhered substance, e.g. raindrops, dust. CONSTITUTION:During the stop of a vehicle or normal running, air is sucked through an air suction port 14 and compressed through the working of a compressor 15 to produce compressed air, which is blown through a compressed air discharge port 11 against the surface of a window 92 by means of a duct 13. As a result, an adhered substance, e.g. raindrops, on the surface of the window 92 is blown off. In this case, coupled with formation of a water repellent silicon deposition film on the surface of the window 92, raindrops and the like are removed with high efficiency. During high speed running, the flow of the open air during running is guided by an air spoiler 12, and through the rise of the flow of the open air along the surface of the window 92, an adhered substance on the surface of the window 92 can be blown off.

Title: Controlling emthod for charging width of photoreceptor in copying machine
Inventor: YAMAGUCHI TOMOYUKI
IPC: G03G21/00
Filed: 1977-10-11
Abstract: PURPOSE: to eliminate developing of unnecessary portions, reduce consumption of developer and prevent the contamination of a corona discharger for transfer by providing a destaticizer near the charger for photoreceptor and removing the charging portions which become unnecessary.  
     CONSTITUTION: A photoreceptor drum 2 is destaticized of excess charged portions by a destaticizer 10 immediately after having been charged with a charger 1. A changeover device cooperating to a changeover lever or the like for feed paper sizes is provided to apply the changeover signal for input to the destaticizer 10. When the original is of a large size, no input signal is sent to the destaticizer 10 and the destaticizer does not actuate. When the changeover lever is changed over to the original of a small size, the input signal is sent to actuate the destaticizer 10. The sctuation of the destaticizer 10 causes the photoreceptor to be charged to a width necessary for copying, thus the photoreceptor which does not produce any surplus charging portion does not nesessitate production of unnecessary developed portions at the time of exposure and development, hence the consumption of toner becomes less and the efficiency becomes higher

Abstract: PURPOSE:To produce spherical low melting point alloy grains having no oxide films by melting and granulating a low melting point alloy, passing the particles through the liquid in a heating zone to spheroidize the particles and solidifying the spheroidal particles with the liquid in a cooling zone. CONSTITUTION:A high boiling liquid is filled into a vertical pipe 2 and a liquid tank 1 and the upper part of the pipe 2 is heated by a heater 4 to form the heating zone A and the cooling zone B. Solder is supplied to a supplying pipe 5 and is heated and melted by the heating liquid in the zone A. The molten solder is controlled of particle sizes by the mesh size of a grid 6, the oscillation frequency of an oscillator 7, etc. and is released from the grid 6 to the zone A. The released solder particles are spheroidized by the surface tension during descending in the zone A and solidify during the passage through the zone B. The solidified spheroidal solder powder accumulates gradually in the liquid tank 1 and the excess liquid is discharged from an overflow pipe 8 according to the accumulation. The spheroidal solder powder having no oxide film is thus produced by the simple method.
