Title: Local structural analyzer
Inventor: DOI SEIZO
IPC: G01N23/227
Filed: 1987-01-14
Abstract: PURPOSE:To achieve an analysis of a local structural of a very small area as well as surface, by irradiating the very small area with intense X rays using a focusing device. CONSTITUTION:A white X ray beam 1 is spectrally analyzed with a crystal spectroscope 2 to obtain a monochroic X ray beam 3, which is focused with a Fresnel zonal plate 4 at a specified position on the surface of a sample 5 to be inspected. As the focal length of the Fresnel zonal plate 4 is inversely proportional to the wavelength, light with a different energy (wavelength) can be focused at a fixed position of the sample 5 by varying the interval (x) between the sample 5 and the Fresnel zonal plate 4. Released ions are detected and measured with a mass spectrometer 6 facing a sample surface and recorded with a recorder 7. Here, with the relaxation following the excitation of inner- shell electrons, ions released from the sample are only confined to the very surface of the sample, and thus information only on the surface thereof can be obtained by detecting the ions.

Title: Burner
Inventor: KAWAGUCHI TATSUO
IPC: F23N1/00
Filed: 1979-01-19
Abstract: PURPOSE: To conduct smooth combustion by a burner by a method wherein injection of fuel is made slowly and ignition is carried out under lower pressure than usual time.  
     CONSTITUTION: When a switch 22 is closed, voltage is applied on the both ends of a Zener diode 18 through a diode 3, a resistor 12. When the gate potential becomes equal to the anode one in a PUT20, current begins to run through the PUT20, a SCR19 is triggered and becomes conductive. Then, voltage is applied on an electromagnetic pump. Since the gate potential falls gradually with the course of time, gradually short becomes the time required until the anode potential of the PUT20 becomes equal to the gate potential of it and the position of the trigger of the SCR19 begins to move. After the elapse of a designated time determined by a resistor 4, a condenser 14, the trigger of the above-mentioned SCR19 is fixed to a designated position and power supply to the electromagnetic pump comes in a steady condition.

Title: Discharge processing electrode for forming ring groove
Inventor: OI NOBUAKI
IPC: B23H9/00
Filed: 1992-01-14
Abstract: PURPOSE:To provide a ring groove having an acute angle at each corner by embodying it so that the thickness lessens gradually from the periphery toward the internal circumference and that the shape is symmetrical to the front and rear, and thereby generating approx. uniform width in the direction over the depth. CONSTITUTION:Processing proceeds in such a condition that the outermost part of a dics-form processing electrode 1 has intruded to the deepest part in a ring groove 3 formed in a work 2. Therein the thickness of the electrode 1 Wa is largest at the outermost part to decrease toward the internal circumference, and the shape is symmetrical to the front and rear. Therefore, the gap between the periphery of the groove 3 and the electrode 1 is kept comparatively large, and electric discharge takes place in a micro-gap part between the outermost of the electrode 1 and the groove 3, and the processing proceeds. No discharge or electrolytic reaction which is unnecessary, does not occur between the periphery of the groove and the electrode 1, which reduces likelihood of generation of poor workmanship such as widening or rounding of the groove.

Title: Method of filling molten metal in vertical type die casting machine
Inventor: EBISAWA SHIZUO
IPC: B22D17/12
Filed: 1980-01-21
Abstract: PURPOSE: To suppress the inclusion of air, the formation of cavities, etc. and produce a high-quality casting with good efficiency by filling molten metal into the product cavity which is open to the atmosphere in the upper part, and closing the open part just before the filling is nearly finished.  
     CONSTITUTION: An upper plunger 10 is placed above an upper sleeve 9, and molten metal M is poured from the sleeve 9 and is stored on a lower plunger 6. The plunger 10 is moved downward and is fitted into the sleeve 9. Next, the plunger 6 is moved upward to flow and fill the molten metal gently and smoothly into the cavity 4. Since the cavity 4 communicates with the atmosphere through an opening 11, the air and gas in the cavity 4 are released to the atmosphere. The near completion of the filling of the molten metal M is detected by the engagement between the upper movement of the plunger 6 and a limit switch 16, and a cylinder unit 15 is driven to move a plunger 14 downward and is fitted into the sleeve 13, by which the opening 11 is closed and further the plunger 14 is moved downward to pressurize the filled molten metal M, whereby the replenishment accompanied with the solidification and shrinkage of the molten metal is accomplished and the formation of cavitites etc. is prevented.

Title: Optical detection system for coin shape
Inventor: TOMONO AKIRA
IPC: G01B11/24
Filed: 1983-01-17
Abstract: PURPOSE:To sort plural kinds of coin by the same mechanism, to reduce size and weight, and to simplify constitution by using a photocoupler consisting of a semiconductor photodetecting element which generates an output current corresponding to photodetection area and a light emitting source opposed to the photodetecting element for measuring the shape size of coins. CONSTITUTION:Coins thrown in through coin slots 4a and 4b roll while falling against a front-surface supporting plate 5 at a sorting part A. There is a gap a little bit narrower than a normal coil thick between a track 8 and a rear-surface supporting plate 7, so thin incorrect coins fall off. Normal coins rolls on the track and the photodetecting element 10 is shielded partially by the coins and its photodetection area is reduced. Therefore, when the photodetecting element 10 generates the output current according to the photodetection area, this current value is measurd to detect variation in photodetection area, measuring the diameter of each coin. The photodetecting element 10 uses a semiconductor reverse bias element with P-N junction.
