Title: Optical device and method for discriminating object
Inventor: WAKATABI TADATAKA
IPC: G01V8/10
Filed: 1992-04-28
Abstract: PURPOSE:To obtain an optical device for discriminating objects which can easily discriminate the distance to an object and whether or not the object can actually become an obstacle. CONSTITUTION:This device is provided with a first and second laser light source devices 1 and 2 the directions of which are set so that the first visible rays 100 emitted from the device 1 can cross the second visible rays 200 emitted from the device 2 at a beam crossing position CP.

Title: Spray container
Inventor: OKAMOTO YOSHIHIKO
IPC: B65D83/42
Filed: 1990-05-25
Abstract: PURPOSE:To permit a container to spray its contents until it becomes completely empty without producing vacant spaces in an inner bag member for allowing the contents to stay therein due to the gatherings of the inner bag member free from elastic contraction by providing a frame member which changes its shape according to the expansion and contraction of an elastic outer bag member. CONSTITUTION:A bag member 7 for filling its contents therein has a frame member 8 interposed between the outer peripheral surface of an inner bag member 71 and the inner peripheral surface of an outer bag member 72. The contents are filled in the inner bag member 71 consisting of a non-elastic film material against the elastic force of the outer bag member 72 consisting of an elastic material such as rubber, while the contents are shot out to the outside through a spray nozzle from the inner bag member 71. The frame member 8, upon expansion of the inner bag member 71, is formed into a nearly cylindrical shape conforming to to the exterior contour of the inner bag member 71 and having a swelling part in its center and, when the bag member is not filled with its contents, frame pieces 8a adhere closely to one another leaving little vacant space therein and the inner bag member 71 is free from hollows due to the gatherings and permits the contents to be sprayed out until it is completely emptied of its contents with none of them remaining therein.

Title: Stator yoke for stepping motor
Inventor: ICHIMURA HIROTAKA
IPC: B29K105/16
Filed: 1992-04-28
Abstract: PURPOSE:To get a stator yoke which is easy to manufacture and can improve the yield rate of a product and gets off with a small number of parts and further is large in intrinsic electric resistance. CONSTITUTION:A can-type stator yoke 1 and a flat-type stator yoke 2 are manufactured by putting the composite powder between soft magnetic metallic powder and thermosetting synthetic resin powder into an ordinary injection molding machine, and heating it for molding. As a result, the manufacture processes becomes further less as compared with the conventional method by a sheet metal press, and besides the number of parts can be made less, and the cut down of the manufacture cost can be expected. Furthermore, since electric peculiar resistance is large, the calorific value also is small, and the current loss is little, and high speed rotation becomes possible. Besides, the tooth of the stator yoke is made in required shape, so it is highly reliable though small.

Title: Matching recognizing method
Inventor: TAGATA GENICHI
IPC: G01N21/93
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To grasp the constitution of plural kinds of object and shorten the recognition time for those objects by specifying reference pattern values of similar candidate objects, and comparing a detected pattern with the reference patterns and extracting an object. SOLUTION: The reference patterns are previously set in a reference pattern storage meas 4 by digitization, as to the plural kinds of object (b). When an image pickup means 1 starts scanning to search for an object (b) of a printed board (c), an image pickup signal, i.e., a detected pattern signal, is set to a storage means 2. As the image pickup means 1 comes closer to the vanity of center of the object (b), the degree of recognition increases, the waveform becomes larger, and the detected pattern signal detects its maximum similarity, e.g. a10 at the peak of the waveform. A comparing means 3 compares the detected pattern with the reference patters and recognizes the presence of the object (b), thereby extracting the object (b). Information as to the object (b) and the coordinates of the maximum similarity are recorded in the storage means 2.

Title: Feed water system of boiling water nuclear reactor
Inventor: ITOYA KIYOHIRO
IPC: G21D1/04
Filed: 1990-05-29
Abstract: PURPOSE:To enable replacement of a feed water pump and a feed water heater or reduction of capacities thereof by providing a steam injector to a feed water system of boiling water nuclear reactor so as to get driving steam of the steam injector directly from a main stream pipe. CONSTITUTION:Into a mixing nozzle 23, a condensate water from a condensate pipe 10 is supplied. Accordingly, spouted steam transfers its kinetic energy to the condensate water during suddenly being condensated at an inside of a throat part 21, and the condensate water becomes high velocity water flow to open a check valve and then flow out. Also, since the high velocity water flow contains condensated water of the steam, temperature of the water is higher than temperature of flowing-in condensate water from the mixing nozzle 23. Accordingly, by using a steam injector 20 instead of a high pressure condensate pump, the condensate water in a condenser 7 can be sent into a nuclear reactor pressure vessel 1 as heated feed water. Since potential energy of the steam is transferred to the water, in the steam injector 20, temperature of the water rises up and therewith capacities of feed water heaters 11 and 13 can be reduced.
