Abstract: The oil cooling system is for the cylinders of an IC engine in which the oil is caused to flow in a very thin film under laminar conditions through an annular oil cooling flow passage surrounding only the outer portion of each engine cylinder. The flow passage is designed to extend axially along the cylinder walls between an annular supply channel adjacent the outermost portion of the cylinder. An annular oil collecting channel is positioned inwardly by a predetermined distance less than the total length of the cylinder to limit the axial length of the cylinder which is cooled by direct contact with flowing oil.

Abstract: The method  for  manufacturing  the  gate  insulating  layers comprises the steps of evaporating a SiO2 material onto  the  gate electrode (2)  formed  on  the  substrate  (1)  at  the  substrate temperature of 350 deg.C and at a mixing atmosphere  of  SiH4,  He and N2o TO FORM A SECOND GATE INSULATING LAYER (8) HAVING 400-800A thickness; evaporating a-SiN:H material onto the layer (8) at  the substrate temperature of 250 deg.C and at a mixing  atmosphere  of NH3 and SiH4 with a rito of 7 to 5 to form a first gate insulating layer (3) having 2500-3500A thickness; and forming  a  third  gate insulating layer (9) by using the same method as the  second  gate insulating layer (8). The plural  gate  insulating  layers  having different etching ratios are formed between the gate electrode (2) and a source electrode (7).

Abstract: The exposure method and apparatus for coating the fluorescent film on the inner surface of panel with  dot  pattern  include:  a panel mount on the upper side and a cabinet for housing the  light source as sembly for light irradiation  on  the  lower  side;  the correcting lens and filter arranged in the space between the panel mount and the light source assembly. The light source assembly  is made of cooling bath, lamp and adjustor to  control  the  exposure length of lamp. In this time,  the  exposure  length  of  lamp  is longer than diameter of lamp, and the shape  of  light  source  is formed in rectangular type by fluctuating  the  lamp  in  vertical direction to moving direction.
