Title: Production of tooth brush sharpened at hair tip to tapered shape
Inventor: TAKAHASHI YASUO
IPC: A46D1/05
Filed: 1994-01-26
Abstract: PURPOSE:To obtain a tooth brush sharpened at hair tips to a tapered shape by immersing the tooth brush into a solvent liquid down to prescribed depth from the pruning plane of fibers and rubbing these fibers from inside of the liquid surface. CONSTITUTION:The brush part of the tooth brush formed by implanting the fibers made of '6, 12 Nylon (R)' to a polypropylene handle is immersed into a methanol. The methanol penetrates down to the inside of flocking holes, is filled therein and is held in the fiber bundles by capillarity. Next, the brush part is immersed into a formic acid soln. down to the prescribed depth from the pruning surface 5 and is rubbed for 15 minutes by a rotary brush 3 from below. The methanol is substd. for the formic acid to dissolve the fibers and partial dissolution begins. The parts to be strongly rubbed are subjected to replacement of the solvent at all times and are chipped off in the stage when swelling progresses and, therefore, the dissolution rate in these parts is higher than in the other parts and tapers are formed. The formic acid to dissolve the fibers does not rise upper than the liquid surface as far as the methanol exists. The entire part of the brush part is again immersed into the methanol liquid and is rubbed. The formic acid is washed away before arriving at the flocking holes of the holes. The booth brush sharpened at the hair tips to the tapered shape is thus obtd.

IPC: H01J9/34
Filed: 1978-03-30
Abstract: PURPOSE: To surely solder an external lead wire to the base of a lamp even if there is a little error in the supplied quantity of solder and flux, by keeping the lamp oblique and supplying the solder and flux into a keyway.  
     CONSTITUTION: The external lead wire 5 is extended out along the keyway 8 provided on the outside surface of an end of the lamp 2. The base 3 is screwed on the end of the lamp. The lamp 2 is kept oblique so that the radial opening face of the keyway 8 is oriented upward and the base is located at the top of the lamp. A reservoir 10 for the flux 20 is thus formed by the keyway 8. The paste-like flux 20 is supplied to the opening of the keyway 8 and reserved in the reservoir 10. The molten solder is then supplied into the reservoir 10 through the opening 19 to evaporate the flux 20 by the heat of the solder. The inside of open edge 3a of the base is wetted with the evaporated flux. The solder flows around on the wetted part and is solidified. As a result, the relative rotation between the base 3 and the lamp 2 is surely prevented.
