Filed: 1981-12-01
Abstract: PURPOSE:To explode various fuels pollution-freely by pressing a part of the suction air into a  medium compression combustion chamber in the middle of a compression stroke, by spraying  the fuel to form an air-fuel mixture, and by injecting the high pressure high temperature gas  during the subsequent compression stroke. CONSTITUTION:The suction air is sucked so as to keep an air ratio of one by a suction damper  55 and is pressed into a medium compression combustion chamber 17 through multiple side  lateral holes 14 up to the middle of a compression stroke, and the fuel is sprayed there through  an injection valve 44 to form an air-fuel mixture. In addition, the chamber 17 is communicated  with a pressure regulating combustion chamber 57 through a fine hole vent line 56 and is regulated at a timing balance between the suction negative pressure and the compressed pressure through the fine hole so that the pressure in the chamber 17 is kept at the optimum combustion pressure even if the suction air quantity is varied in accordance with the fuel injection  quantity. When the compression stroke proceeds further, the pressure in the chamber 17 is  kept the same, the medium compression suction air on the lateral holes 14 is compressed to a high pressure and high temperature and is injected into the chamber 17 through a hot air injection valve 23 at an ignition time and is exploded under combustion, then an explosion valve  20 is pushed open by this pressure to apply the explosion force to a piston 1.

Title: Method for discriminating aggregation image
Inventor: SATO KOJI
IPC: G01N33/543
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To obtain a highly generic method for discriminating an aggregation image quickly by discriminating an aggregation image based on the mean value of signals corresponding to the brightness of respective wells, the standard deviation thereof, and the absorbance obtained through logarithmic conversion of the signal. SOLUTION: A microplate 1 is irradiated from below with a light source 2, the transmitted light is picked up as an image by a CCD camera 3 and an image processing section 4 divides a well into a plurality of seconds in order to make a decision based on the brightness signal from each section. The brightness signal can be calculated in simple form by associating each section with the pixel of the CCD camera 3. The decision results are delivered from an output section 6 through a control section 5. The difference between the maximum and minimum values of absorbance determined through logarithmic conversion of the brightness increases in the order of aggregation, weak aggregation and non-aggregation.  When the boundary values are predetermined between aggregation and weak aggregation and between weak aggregation and non- aggregation for the difference between the maximum and minimum values of absorbance and compared with a measurement, aggregation, weak aggregation and non-aggregation can be discriminated.
