Title: Linear component extraction method
Inventor: OTSUKA MICHIO
IPC: G06T7/00
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To fast and stably detect a straight line, i.e., an extraction object. SOLUTION: When a scanning range is detected, the counter point corresponding to a peak point is shifted one pixel by pixel to one of both ends to the other of the scanning range and at the same time, the mean value of density is calculated among the pixels set on a straight line connecting the peak point to each counter point. This mean value of density is used as the image information value. When the scanning of the counter point is over in the scanning range, a desired straight line is extracted out of the image information value for each straight line.  Thereby, it is possible to fast and stably extract the straight line, i.e., an extraction object despite its low contrast just by calculating the mean value of density among the pixels set on a straight lie connecting together the points set on the 1st and 2nd lines and without using the space differential processing nor other filtering methods.

Filed: 1990-11-27
Abstract: PURPOSE:To solve such a problem as noise and air pollution due to discharge of exhaust gas by cooling a car room by way of actuating a main refrigerant compressor with an engine at the time of traveling the car and by air-conditioning the car room by way of actuating a sub-refrigerant compressor with an electric motor at the time when the motor stops. CONSTITUTION:In the case of cooling drive by actuation of a main refrigerant compressor 4, a sub-refrigerant compressor 6 is once actuated and a refrigerant passage of a four-way valve 22 is certainly fastened on the refrigeration side in the state where an electromagnetic coil of the four-way valve 22 is made not electrified. Thereafter, power to an electric motor is shut off and the sub-refrigerant compressor 6 is stopped working, and an electromagnetic clutch is electrified to actuate a main refrigerant compressor 4. Refrigerant thus discharged from the main refrigerant compressor 4 flows as an outdoor heat exchangers 7 - a check valve 20 - a receiver 11 - refrigeration decompression device 9 - an indoor heat exchanger 8 - an electromagnetic valve 18, and then it is absorbed in the main refrigerant compressor 4 and repeats the above cycle. Consequently, refrigeration inside of a car room is carried out as air which is heat-exchanged with refrigerant of low temperature and low pressure and refrigerated in the indoor heat exchanger 8 is discharged inside the car room by an indoor fan 25.

IPC: F16D41/06
Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To facilitate assembly work and increase strength of a holder in a one-way clutch. SOLUTION: In a one-way clutch 3 of such type that a cam face 10a for forming a wedgelike space is provided on a peripheral face on one hand of inner and outer rings 10, 11 and a roller 13 is arranged in each wedgelike space, a wall face on one hand of a column part 12c between pockets 12a in a holder 12 has such shape that an intermediate part in the radial direction is recessed by swelling its inside diameter side and outside diameter side.

IPC: C30B25/02
Filed: 1991-12-13
Abstract: PURPOSE:To make it difficult to deposit reaction sub-products in the periphery of a reaction gas introduction hole. CONSTITUTION:The periphery of a reaction gas introduction hole 12 is provided with an annular inactive gas spout member 26 provided with many inactive gas spout holes 25. An inactive gas spouts from the inactive gas spout hole 25 toward an exhaust port 13. While this inactive gas promotes a flow of exhaust gas from a reaction space 4, it flows forcedly toward an exhaust passage 13. Therefore, reaction products 22 contained in the exhaust gas are exhausted to the exhaust passage 13 rapidly without being deposited in a large amount near the periphery 23 of the reaction gas introduction hole. This makes it difficult to deposit reaction sub-products in the periphery of the reaction gas introduction hole.

Title: Operating method for horizontal crusher
Inventor: KINOSHITA MASAAKI
IPC: B02C17/00
Filed: 1991-12-13
Abstract: PURPOSE:To satisfy the operation conditions of a low load required from a boiler capacity by controlling the number of revolutions of a drum corresponding to the amount of coal supplied. CONSTITUTION:A drum 2 is driven by a pole change motor 12 through a reduction gear 8. The coal level in the drum 2 is lowered along with the decrease in the amount of coal supplied, and when the level comes down to a prescribed load, the height of ball lifting is lowered by decreasing the number of revolutions of the pole change motor 12. The coal level can be raised through the reduction in the crushing capacity brought by the decrease in the ball lifting height. Since the number of revolutions of the drum 2 can be controlled corresponding to the amount of coal supplied, the operation at lower level of noise generation and with reduced load can be accomplished, resulting in the simultaneous reduction of power consumption due to the partial loading.
