Abstract: PURPOSE: To prevent the top of an pre-coated substance layer from scattering in centrifugal separation and make the thickness of the pre-coated substance layer uniform, by providing an adjusting plate so that the inside surface of the plate projects toward the interior of an opening of a basket.  
     CONSTITUTION: Pre-coated substance layer adjusting plate 10, which is shaped as a hollow disc, is provided at the top of an opening of a basket 2 so that the inside surface of the adjusting plate projects toward the interior of the opening of the basket. A processed substance is thrusted onto the side wall of the basket 2 by a centrifugal force. The processed substance pre-coated to the side wall is automatically displaced by the centrifugal force from the minor-radius bottom of the basket 2 to the major- radius top of the basket. At that time, the liquid contained in the processed substance is filtered. Solids filtered by the side wall are picked out of a main body through an outlet port 7. The liquid is drained through a pipe 8 under the bottom 1a. The thickness of the processed substance pre-coated to the side wall is made uniform by the adjusting plate 10 provided at the top of the opening of the basket 2.

Title: Decision device for surface pattern of fruit
Inventor: NAKADA HIROSHI
IPC: G01N21/88
Filed: 1991-06-11
Abstract: PURPOSE:To speedily perform a decision making process by evaluating the whole image according to a specific evaluation value and deciding the pattern on the surface of the fruit. CONSTITUTION:The image signal outputted by a color CCD camera 2 is passed through an A/D converter 41 in a processor 4 by color components and latched in respective image memories 42. An arithmetic part 44 extracts effective lines from data from the image memories 42 by removing lines where unnecessary picture elements more than a specific number such as a part where a background light or light source light is totally reflected are present as to lateral lines and longitudinal lines set in the image. Then the arithmetic part 44 calculates the absolute value of the differential value of each color component value as to the effective lines. The frequency at which the value crosses a predetermined value is detected as a line evaluation value. The mean value of line evaluation values of all the effective lines is calculated and the mean value is used as a stripe evaluation value indicating the extent of stripes of, for example, an apple 6 to discriminate between a striped apple and an equal- color applied.

Filed: 1990-06-22
Abstract: PURPOSE:To prevent the generation of flows by gripping the handle part of a casting mold contg. solidified bullion in a hand to be exclusively used of a robot, moving the casting mold to the position above a cooler, vertically moving the casting mold at a high speed, retreating the casting mold and mounting the bullion above the cooler while positioning the casting surface side thereof downward.

Filed: 1980-11-26
Abstract: PURPOSE:To prevent a leak from the sealed portion by glass brazing an aluminum pipe on the end portion of an exhaust pipe connected to an enclosure and sealing and cutting airtightly by squashing the aluminum pipe after exhaust. CONSTITUTION:The opening end of the enclosure 1 of a bulb, made of glass, ceramics or the like, is sealed with a metal cap 2 in which an exhaust pipe 3 is arranged, and an aluminum pipe 4 is brazed on the end portion of the exhaust pipe 3 with glass. Then, after connecting the aluminum pipe 4 to the manifold of an exhaust bench and exhausting the inside of the enclosure 1, the aluminum pipe 4 is sealed and cut by squashing with an air pincher. Accordingly, as aluminum is soft, easily adapted to surroundings and not liable to form on its surface an oxidized layer easily exfloliating as copper is, a leak from a sealed and cut portion is prevented perfectly without any coating for stopping the leak.
