Inventor: KAWAMURA HIDEO
IPC: F02B19/16
Filed: 1991-07-25
Abstract: PURPOSE:To improve the combustion efficiency at the time of partial load in a two-cycle thermal insulation engine that has used methanol large in evaporating latent heat and high in ignition temperature for fuel. CONSTITUTION:A head liner 11 consisting of ceramics and an auxiliary combustion chamber 2 used with a heat insulator 21 are unified as one body, while plural pieces of connecting holes 4 being interconnected to a main combustion chamber, and these holes 4 are formed so as to make air out of the connecting holes 4 advance a peripheral wall part of the auxiliary combustion chamber 2 at a compression stroke, and to make combustion gas out of the auxiliary combustion chamber 2 come to a turbulent flow of the main combustion chamber at a combustion stroke. Therefore, when a fuel spray out of a nozzle 3 is sprayed in a peripheral wall direction of the auxiliary combustion chamber 2, an air-fuel mixture is efficiently generated, and further combustion gas being sprayed out of the connecting hole 4 is also quickly ignited in the main combustion chamber.

Title: Bearing seal
Inventor: KOBAYASHI NOBUYUKI
IPC: F16C33/78
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To provide a bearing seal to improve mounting ability of the bearing seal on a bearing and eliminate a fear of a gasket part being stripped off and a crack occurring. SOLUTION: This bearing seal comprises a gasket part 221 formed of an elastomer and integrally protruded radially from the inside surface of the outer peripheral edge 21a of a reinforcing plate 21; and a plurality of spacers 222 in a peripheral direction positioned on the inner side of the outer peripheral edge 21a. In mounting of a bearing seal 20, the gasket part 221 is temporarily brought into a stripped-off state as a result of the gasket part being interfered with the protrusion edge 12 of an outer ring 10. However, by keeping push-in of the bearing seal 20 until the spacer 222 is brought into a squeezed state as a result of the spacer being pressed against the rise surface 11a of the inside in an axial direction of a lock groove 11, the gasket part 221 passes through the protrusion edge 12 and enters a lock groove 11 and the occurrence of stripe- off is prevented.  After completion of press-in, the gasket part 221 is forced into close contact with or access to the rise surface 11b of the outside in an axial direction of the lock groove 11 through the restoration force of the spacer 222.

Title: Manufacture of field effect type semiconductor device
Inventor: EZAKI TAKAYUKI
IPC: H01L29/78
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To manufacture a field effect type semiconductor device where the vertical level difference of a side wall is small and an upper-layer wiring can be easily machined without any deterioration and fluctuation of characteristics. SOLUTION: The side wall of, for example, polycide film 15 which is a gate electrode is formed by SiO2 film 25 and BPSG film 26 and heat treatment is performed at a temperature where the SiO2 film 25 is fumed into a fluid but the BPSG film 26 cannot be turned into a fluid, thus reducing the vertical level difference of the side wall. Also, the diffusion of an impurity from the BPSG film 26 to the polycide film 15 can be prevented by the SiO2 film 25, heat treatment temperature can be decreased since only the BPSG film 26 is turned into a fluid, and for example the occurrence of a crystal defect in the Si substrate 11 can be prevented.

Title: Fruit recognizing device
Inventor: TOKI HARUMITSU
IPC: G06T1/00
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To appropriately extract the image of fruit by obtaining a threshold even in the case of image small in luminance change by deciding the threshold of binarization from the luminance value of lowest luminance peak. SOLUTION: A CPU 4 binarizes the signal processing result image by inputting the image in a preprocessing part 10. At a succeeding feature extraction part 11, the feature of object such as fruit is extracted by analyzing the binary image. In a recognition part 12, whether it is the fruit or not is judged by calculating the feature amount of the extracted object. In this binarizing processing, the signal processing result image is inputted for every unit of one picture element. Next, the inputted signal processing result image is decomposed into R, G and B images, the luminance of image from the lowest value to the highest value is linear-transformed into values from '0' to '255' and the change amounts of R, G and B images in luminance are enlarged. Afterwards, the histogram is prepared and smoothed by calculating the luminance distribution in the R, G and B images.  In this case, the lowest luminance peak of the first peak watched from the low luminance side of the histogram is differentiated by a differentiation coefficient less than '10' and detected and this luminance value is averaged, so that the threshold can be decided.

Title: Photoresist solution storage system automatically controlling pneumatic pressure in photoresist storage tank
Inventor: SU SHIEN-JUN
IPC: H01L21/027
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To prevent the quality of photoresist solution from deteriorating by a structure, wherein photoresist solution pushes the air accumulated in a storage tank, when it is carried into the storage tank and discharges the accumulated air to the outside through a controller and an exhaust pipe. SOLUTION: Photoresist solution applies pressure to the air which accumulated at the upper part of a storage tank 32, when it is fed into the storage tank. When the pressure of the air accumulated in the storage tank 32 is higher than a specified level, the ball in a check valve is pushed so as to be separated slightly from a funnel, in order to discharge the accumulated air through the discharge pipe of the check valve. Since a controlling 36 is a pressure controlled check valve, it opens/closes the check valve, depending on the pressure in the storage tank 32 to automatically discharge the air accumulated in the storage tank 32 through the controller 36 and an exhaust pipe 38.
