Title: Digital image pickup device for selecting distortion correction
Inventor: HIGASHIYAMA YASUNARI
IPC: H04N5/335
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To provide a digital image pickup device by which the processing time of photographing or reproducing is preventing from being long unless a user intends it, by using an inexpensive lens with a comparatively large distortion, selecting whether distortion correction is executed or not at the time of distortion correction in image data and, moreover, permitting selection to be possible at the time of reproduction concerning a selection period. SOLUTION: Whether to perform distortion correction is selected by a distortion correction operating part 13. At the time of reproduction, a buffer memory 5 is permitted to display a prescribed image on a reading video monitor 12, etc., by a recording medium 9. When the user selects distortion correction, an aproximate polynomial formula operation and an interpolating operation are executed. No distortion correction can be selected land whether to perform distortion correction can be selected at the time of reproduction so that the processing time of photographing and reproducing is shortened.

Title: Windshield wiper control device
Inventor: FUKATSU YOSHIAKI
IPC: B60S1/08
Filed: 1982-05-31
Abstract: PURPOSE:To control the operation of a windshield wiper device in a highly accurate manner according to a difference in contrasts of a singpost based on the presence of a water drop sticking to a windowpane, by projecting an actual image of the signpost having both bright and dark parts of light from a floodlight installed outside a car to a light receiver installed inside the car. CONSTITUTION:When a light bulb 4 of a floodlight 1 attached to the front part of a car bonnet is lighted, light passes through a translucent sightpost 6 having a striped pattern consisting of bright and dark parts of light, a convex lens 7, a reflector 8 and an infrared light transmitting filter 10, and infrared light alone is projected to a light receiver 2 through a windowpane 13. At the light receiver 2, an actual image of the sightpost 6 is projected onto a light detector 12 composed of bright and dark light receiving elements 12a and 12b. At this time, it means that a difference in light receiving signals outputted out of each of these light receiving elements 12a and 12b shows the degree of contrast for the said actual image according to each case when waterdrops stick to the windowpane 13 or not. So, according to this difference in the said light receiving signals, the operation of a windshield wiper device is automatically controlled.

IPC: D01H4/44
Filed: 1995-04-18
Abstract: PURPOSE: To effectively improve soft starting control of all the asynchronous motors of large output by performing soft starting control of the other all asynchronous motors with only a single soft starting control of a single asynchronous motor. CONSTITUTION: A rotor spinning machine transmission equipment is driven by asynchronous motors M1-M5. The asynchronous motors M1-M5 are changed from a static state to a high-speed operating state in the drive number of revolutions, under a inertial mass load of the transmission equipment.

Title: Operating method of dry type dust collecting device for blast furnace gas
Inventor: ASAI TAKEJI
IPC: B01D46/04
Filed: 1981-06-15
Abstract: PURPOSE: To prevent bag-filter damage through sudden increase of gas flow by turning dry type dust collectors for blast furnace gas in a filtration stage to a back-washing stage in case of sudden increase of treated gas flow during dust removal operation wherein part of plural dry type dust collector is subjected to back-washing and dust deposit is removed from a back-filter.  
     CONSTITUTION: In a stage wherein after high temp. blast furnace gas containing dust is passed through coarse particle dust collector 2, the contained dust is eliminated in a dry type dust collector 3 comprising a plurality of elements 13AW13F, usually one element among the plural elements is subjected to back- washing one by one alternately and dust deposit on back-filters 15AW15F in said elements is removed in series. On sudden increase of treated gas flow due to a blow-down of a blast furnace, the element being back-washing is turned to filtration or dust collection operation as other elements. Bag-filter damage due to excessive filtered gas flow is prevented by making bag-filters of all elements take partial charge of treating suddenly increased gas flow.

IPC: G01N21/59
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To discriminate water and mud by providing a constitution wherein a slit is provided for a transparent optical guide and a detection part is provided so as to be movable in a hollow part within the optical guide. SOLUTION: A hollow part 1A and a slit 1B are provided in the longitudinal direction of an optical rod 1. An optical transmission line 2 comprises an input side optical fiber 3 connected to an optical source 6 and an output side optical fiber 4 connected to a light receiving part 7. A detection part 5 is constructed such that tips of both the fibers 3, 4 are set to face each other. The light made incident to the fiber 3 changes its direction at a cut surface of the tip, comes out of the fiber once and passes through a slit 1B, and thereafter it is reflected by an optical path changer 9 and converged into the fiber 4 through the slit 1B. When mud or the like enters the inside of the slit 1B, the transmission of light is decreased at the slit 1B so that the light transmission incident to the fiber 4 is decreased.  Accordingly, based on variation of the quantity of light received at the light receiving part 7 the existence of mud in the vicinity of the slit 1B can be detected continuously.

IPC: E04B1/19
Filed: 1995-04-19
Abstract: PURPOSE: To easily make a gusset type joint used for truss construction. CONSTITUTION: A joint 10 for truss construction is constituted by welding gusset plates 14, 16 by means of dispersing them on two main surfaces 12a, 12b of a relay plate 12.

Title: Method of regenerating coke contaminated catalyst
Inventor: AASAA REIMONDO GURIINUTSUDO
IPC: B01J38/42
Filed: 1986-04-25
Abstract: Particulate catalyst which has been used in a hydrocarbon conversion process such as catalytic reforming is regenerated in a moving bed regeneration zone (12). The catalyst being regenerated is passed into the top of the zone (12) and slowly moves downward as a dense bed (14, 19, 20) which is contacted successively with an oxygen-containing gas stream (31), a temperature-adjusting gas stream (30) and either a drying gas stream (37) or a chlorination gas stream (39) or both at different elevations within the regeneration zone (12). A key feature involves employing a portion of relatively hot combustion gas (26) withdrawn from one portion of the zone (12) as the temperature-adjusting gas stream (30) in a different portion of the zone after compression, with the remainder of the compressed combustion gas (27) being cooled (32) and recycled to the combustion zone as the gas stream (31). This eliminates the need to employ a heater to provide a suitable heating gas stream.
