Title: Ultrasonic wave generation element
Inventor: NOMURA NOBORU
IPC: G01S7/521
Filed: 1979-02-20
Abstract: PURPOSE:To realize the ultrasonic wave generation element featuring a long life time and the low production cost, by forming the noncrystal alloy layer onto the piezoelectric substance. CONSTITUTION:Noncrystal alloy layer 12 featuring the composition of T1-XGX (0.1<=X<=0.3; T: transition metal of more than one kind including at least iron- group metal; G: semimetal of more than one kind) is formed to piezoelectric substance 11 composed of the barium titanate, the crystal or the like and at the area touching at least the ultrasonic wave propagation medium. Then electrode 13 of one side is formed in touch with layer 12, and electrode 14 of the other side is formed to oppose to layer 12 via substance 11. As layer 12 is formed through the sputtering , the heat generation due to absorption of the ultrasonic wave the adhesion boundary is never caused. Thus no deterioration is caused to the element, and accordingly the life time can be increased.

Filed: 1990-01-31
Abstract: PURPOSE:To surely photograph only a necessary target to be inspected from a traveling vehicle and to inspect a track based upon the photographed image by mutually compar ing output signals obtained from a track structure detecting means and a track informa tion output means by a comparing means. CONSTITUTION:The output signals obtained from a track structure detecting means 1 and a track information output means 2 are mutually compared by a comparing means 3 and the image of the structure is photographed by an image pickup means 4 based upon the compared result. It is necessary to approximately fix the relation of respective positions of three objects, i.e. a specific structure on the track detected by the means 1, a known structure on the track whose information relating to its existence is outputted by the means 2 and a target to be inspected on the track which is photographed by the means 4, and the same object may be used for the three objects. Even if many targets to be inspected exist on the track at random, the images of the targets can be surely photographed when the targets have fixed positional relation with the specific structure and known structure on the track. In addition, defects on the photographing of the targets to be inspected based upon the output of only the means 1 can be compensated based upon the output of the means 2.

Title: Laminate-worked preform and method and device for molding said preform
Inventor: KRISHANKUMAR SUPPAYAN M
IPC: B29C49/22
Filed: 1985-02-05
Abstract: This relates to laminated preforms, the method of forming such preforms and products which may be beneficially formed utilizing such preforms. Most particularly, this relates to a preform which has formed as part of the injection molding thereof two layers of barrier material which are disposed within two layers of thermoplastic resin and having received therebetween a solid core of thermoplastic resin. The specific method of forming the preform permits the barrier material layers to be of a greatly reduced thickness as compared to such layer tick- nesses permissible in the past, with the result that the barrier material layers in the blow molded articles are of a thickness recognized to be acceptable for the barrier function. The barrier material layers may be selectively terminated along the length of the preform so as to permit portions of the resultant blow molded article to be removed and reused.

Filed: 1979-02-20
Abstract: PURPOSE: To accomplish a proper torque adjustment in a very simple manner by fastening the peripheral end of the spring on a fastening section adapted to turn along the periphery thereof.  
     CONSTITUTION: A spring 9 is placed in a space 15 and the peripheral end 10 thereof is fastened on the fastening section 16. After the fitting section 3 of the fitting piece 12 and the spindle 2 are fully arragned, the rotary frame 14 is moved along the axis of the spindle 2 and put together with the boey 1. Consequently, the fitting piece 12 inserts by itself into the fitting section 3. Then, upon the turning of the rotary frame 14, the fastening section 16 turns along the periphery of the spring 9 to wind the spring 9 in sequence. In this winding process, an engaging convex section 6 and a mating concave section 17 move relatively and the retaining surface 18 of the convex section 17 comes in contact with the retaining surface 7 of the concave section into which it is fitted in succession. Thus, the return of the rotary shaft due to the accumulation of charging force toward can be retained at each small winding angle.

Title: Polyester resin and sheety object, blow molding, and stretched film made therefrom
Inventor: MATSUI YOSHINAO
IPC: C08J5/18
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To obtain a polyester resin excellent in transparency, gas barrier properties, heat resistance, mechanical properties, and flavor retention by selecting a polyester resin mainly consisting of ethylene terephthalate repeating units and showing specified or smaller increments in the contents of acetic acid and formic acid when injection- molded at a specified temperature. SOLUTION: The increments in the contents of acetic acid and formic acid should be each 100 ppb or below when injection-molded at 290 deg.C. For example, it is realized by practicing the melt polycondensation at the lowest possible temperature for the shortest possible time, keeping the reaction mixture in a molten state at the lower possible temperature for the shortest possible time, extruding the melt through fine holes in a nitrogen atmosphere, and forming the extrudate into chips. If required, the solid phase polymerization of the chips is performed. It is desirable that all of the subsequent steps are practiced in a nitrogen atmosphere. Further, it is effective that after the chips are treated with water, steam, or the like before and/or after the solid phase polymerization to temporarily increase the water content of the chips, the chips are dried.  This resin is useful for a container or a packaging material for foods, beverages, etc.

Title: Method and device for image processing
Inventor: SHIBATA MORIHIKO
IPC: G06T1/00
Filed: 1990-01-30
Abstract: PURPOSE:To shorten the time required for the binary image processing and to improve the processing accuracy by dividing the image of a model and a digital image to be processed into plural areas and using the feature values included in these areas for comparison carried out between the model and the digital image. CONSTITUTION:A signal converting part 6 converts the analog picture signal given from an image pickup part 1 into a digital picture signal. A feature value extracting part 9 extracts the feature value of the digital image data received from the part 6. Then a digital image is divided into plural small areas for extraction of the feature value of the digital image. A digital image of a model is compared with a subject digital image in the small areas of both digital images. Thus the primary position matching is performed. At the same time, those small areas are integrated into a medium area and the feature values of both digital images are compared with each other in the medium area for execution of the secondary position matching. Thus it is possible to attain the accurate position matching and also to perform the checking/identifying processes of a subject at a high speed.
