Title: Nonvolatile semiconductor memory device
Inventor: KIRISAWA RYOHEI
IPC: H01L21/8247
Filed: 1984-09-03
Abstract: PURPOSE:To enable to rewrite a nonvolatile semiconductor memory device at higher speed by extending a conductive projection on a reverse conductive type high density impurity region to a semiconductor substrate through a tunnel insulating film along the side wall of a floating gate, thereby reducing a tunnel region. CONSTITUTION:A projection 16 is extended along a side wall through a tunnel insulating film 19 remaining on the side wall of a floating gate 13, and is contacted directly with an N<+> type layer 122. Thus, electrons are communicated through the film 19 on the side wall of the gate 13, and since the occupying area of the tunnel region depends upon the thickness of the gate 13, the tunnel region can be reduced. Accordingly, a rewriting can be performed with a low writing voltage by the electric field concentration upon reducing of the tunnel region. Since the film 19 extends perpendicularly to a P type silicon substrate 11, the occupying are of the film 9 in a memory cell becomes extremely small to be adapted for microminiaturization of the memory cell.

Title: Self-priming mechanism of volute pump
Inventor: SUZUKI KAZUHIRO
IPC: F04D9/02
Filed: 1980-12-22
Abstract: PURPOSE: To prevent air from being induced again together with priming in a volute passage by a method wherein a water flow control plate is arranged on a volute wall at the side of a self-priming hole so as to surge up the water flow as a whole near the self-priming hole.  
     CONSTITUTION: The water flow surges up as a whole as indicated with the arrows 15 and 16 near the self-priming hole 10 by arranging the water flow control plate 13 on the volute wall 2b at the side of the self-priming hole 10. Consequently, even when the quantity of the priming in a water basin 4 is small, a same operating state as that attained by a large capacity water basin can be realized, because no vortex owing to the strong negative pressure just below the self-priming hole 10 is generated above an opening and once removed air is not induced together with the priming again in the volute passage 2a.
