Title: Low reflected wave type floating wave dissipating bank
Inventor: UEDA HIROYUKI
IPC: E02B3/06
Filed: 1994-02-01
Abstract: PURPOSE:To construct a wave dissipating bank economical as well as of high performance absorbing the energy of incoming wave and suppressing the energy of reflected wave and penetrating wave to a small degree by providing the lateral ends of a floating wave dissipating bank body additionally with U-shaped oscillation-reduced water tank filled with air at the upper part. CONSTITUTION:U-shape water tanks 5 are additionally provided at the lateral end parts of a floating wave dissipating bank body 1, and air is filled in the upper space of the tank 5 as an air sealed part 8. The center of the bank body 1 is formed into deformed sector cross section so as not to generate new wave even if the bank body 1 is rotated around the center of buoyancy B. The cross section easily oscillated by incoming wave 2 from the offing is formed to absorb the energy of reflected wave 3 in a large degree. In addition, the wave height is reduced, and the kinetic energy of the dam body 1 is absorbed by the water tanks 5. In this case, the rear face of the bank body 1 is formed into a circular arc shape around the center of buoyancy B so as to hardly generate penetrating wave. This results in obtaining a wave dissipating bank economical as well as of high performance suppressing energy to a small value.

Abstract: PURPOSE:To form the shapes of cells of the extreme shadow parts as high free flow cells of a high dot per cent (ratio of a cell area to a printing area) by forming the shapes of the cells of the extreme shadow parts in such a manner that the screen lines of an approximate arc are made into scalelike arrangement. CONSTITUTION:The shapes of the cells of the extreme shadow parts are so formed that the screen lines of the approximate arc are made into the scalelike arrangement. Then, the free flow cells having high dot per cent are obtd. and the ink in the cells flows one after another into the cells on the downstream side until the ink is admitted about 100% into the cells if scraping of the ink is executed by a doctor. An improvement in density is then resulted. The shapes of the cells in highlight parts are formed to be long holes which are increasingly longer in the relative ink scraping direction of the doctor. These long holes are so formed as to be gradually longer as the dot per cent increases. As a result, the ink is admitted about 100% into the cells of the highlight parts if the scraping of the ink is executed by the doctor. The density is thus improved and the various gray level gradation of the highlight parts is improved.

Filed: 1982-02-25
Abstract: PURPOSE:To discriminate a true target from a false target, by comparing a parameter obtaned by deriving a distance and active and passive receiving levels, with a parameter prepared in advance. CONSTITUTION:A radar pulse generated by a transmitter 4 by an active operation is reflected by a specified object, and is inputted to a signal processor 6 through a receiving circuit 3. The processor 6 derives a distance from an arrival time of the pulse, and detects and saves a parameter from a signal level. Subsequently, by a switching controller 5, the system is made to execute a passive operation, radiation radio waves from a target are received by the circuit 3, and the parameter is detected by the processor 6. These parameters are stored by relation to the distance, and are outputted from a reference value signal generator 8. On the other hand, in the actual operation state, in the same way, parameters in case when the operation is active and passive are derived and are inputted to a comparing and deciding device 7. A parameter of a true target corresponding to this distance is supplied in advance to the deciding device 7, and when both of them are compared and are equal, a signal showing that the target is a true target is outputted to an output terminal 9.

Title: Power protective device for welding
Inventor: HIRASAWA KAZUNARI
IPC: H02H5/04
Filed: 1978-03-14
Abstract: PURPOSE: To detect rapidly abnormal temperature when it occurs by interposing a thermocouple between the primary winding and the secondary winding of welding transformer.  
     CONSTITUTION: The thermocouple 5 consisting of a thin wirework is interposed between the primary winding 2 and the secondary winding 4 wound around the iron core 1 of welding transformer, and when abnormal temperature occurs, the input of welding power source is interrupted by means of the thermoelectromotive force of the thermocouple. Thus, a thermoelectromotive force is generated in rapid response to the temperature rise of transformer and the primary side of the welding transformer becomes off-state, thus preventing the thermal destruction of welding transformer. Also, since the thermocouple is a thin wirework, the formation of welding transformer is very easy because the secondary winding of the welding transformer is not projected in a convex form as is the case when the conventional thermoprotector is used.

Title: Lost wax casting method
Inventor: SASAKI NOBUYOSHI
IPC: B22C9/08
Filed: 1983-02-25
Abstract: PURPOSE:To prevent the generation of a defect such as blowhole and to improve the yield of a product by providing a restricting part in a runner, cooling forcibly and quickly the entire part of a casting mold and solidifying the molten metal like a shell from the part which contacts with the inside surface of the casting mold. CONSTITUTION:A casting mold 60 with the sprue faced upward is placed on a carriage and a molten metal is poured therein. Mist-like water is sprayed to the mold 60, by which the mold is quickly cooled. The entire part of th melt that contacts with the inside surface of the mold solidifies like a shell or skin. The part near a runner 68 and a restricting part 70 has a large heat capacity and since said part contacts with a spure bar part 64 contg. a large amt. of the melt, the decrease in the temp. of the melt is low. The part 70 in particular is overheated and is therefore harder to cool. Therefore the solidification progresses successively toward the inside as shown by (a), (b), (c), (d), thus having unidirectionally solidified texture. The melt prior to solidification existing in the central part of a pattern part 66 communicates with the melt in the runner 68, the part 64 and the sprue 62 and therefore the melt in the part 66 is always pressurized and the effect of feeding is generated until the casting ends.
