Title: Process for irradiating flat stock organic polymers
IPC: C08F2/54
Filed: 1956-01-10
Abstract: A flat stock organic polymer is irradiated with a circular beam of high energy radiation, particularly high energy electrons, by passing the polymer under the beam in such a manner that the centre of the beam impinges on an edge of the flat stock while the portion of the radiation beam of lower intensity radiates outwardly toward the outer edge of the flat stock, and thereafter re-introducing the flat stock into the high energy radiation beam so that the edge of the flat stock which received the higher radiation intensity due to being subjected to the more intense portion of the beam, is now subjected to the peripheral portion of the beam of lower intensity, while the edge of the flat stock which initially received the lower intensity radiation is in turn subjected to the higher intensity radiation from the high energy radiation beam.  In a preferred method, a plurality of superposed layers of polymer may be continuously passed under an electron beam, a sufficient number of superposed layers being employed so that a negligible quantity of electrons penetrates through the layer farthest from the source of high energy electrons. The polymer may be polyethylene, chlorinated or chlorosulphonated polyethylene, nylon, natural rubber, a copolymer of butadiene and styrene or acrylonitrile, a silicone rubber, polyacrylonitrile or polyethylene terephthalate.  Specifications 773,529 and 805,819 are referred to.ALSO:A flat stock organic polymer is irradiated with a circular beam of high energy radiation, particularly high energy electrons, by passing the polymer under the beam in such a manner that the centre of the beam impinges on an edge of the flat stock while the portion of the radiation beam of lower intensity radiates outwardly toward the outer edge of the flat stock, and thereafter re-introducing the flat stock into the high energy radiation beam so that the edge of the flat stock which received the higher radiation intensity due to being subjected to the more intense portion of the beam, is now subjected to the peripheral portion of the beam of lower intensity, while the edge of the flat stock which initially received the lower intensity radiation is in turn subjected to the higher intensity radiation from the high energy radiation beam.

Title: Improvements in the manufacture of oxychlorides of copper and of anticryptogamic products containing them
IPC: C01G3/06
Filed: 1933-01-11
Abstract: Copper oxychloride is obtained by acting on copper or materials containing it, at temperatures say up to 50 DEG  C. and in the presence of an air current or oxygen with a solution of a chlorine compound capable of forming "chlorine of an oxidizing character," together with bodies or compounds promoting the formation of such chlorine in such amount that no free chlorine is formed or liberated. "Chlorine of oxidizing character" is defined to mean chlorine which in solution and in the presence of a body having an affinity for oxygen will act on the water and either form peroxides such as hydrogen peroxide or liberate oxygen, and it may be furnished by a chlorine compound of a heavy metal or metalloid, but preferably from aqueous solutions of hydrochloric acid or an alkali metal chloride. Compounds promoting its formation may be chloric, perchloric, permanganic, persulphuric, or chromic acids or their salts; or preferably nitric acid or an alkali metal nitrate which are used in such quantities that no free nitrogen oxides appear in the solution. The solution for attacking the copper may contain hydrochloric and nitric acids in respective concentrations of 50--80 and 2--10 grms. per litre and the attack may proceed in an acid, neutral, or basic medium, whilst in a modification, the copper is attacked in a basic medium in the presence of mother liquors from the manufacture of copper sulphate, whereby a mixture of oxychloride and basic sulphate of copper is produced.  In the said modification, the attack may proceed in a first phase in the presence of sulphuric acid to form copper sulphate, and be continued with the mother liquors from such formation without further addition of sulphuric acid.  The process may be carried out in a tower fitted with a false bottom, which, for the joint production of copper sulphate and the oxychloride-basic sulphate mixture, is connected to crystallizing vessels, the solution circulating continuously between the tower and crystallizing vessels during the copper sulphate production.  For use as a fungicide, the oxychloride or mixed oxychloride-basic sulphate product is oxidized, mixed with lime preferably in the form of calcium oxide, dried if necessary, neutralized by carbon dioxide, and mixed with an inert substance and/or a substance having high adhesive power such as dextrin.  Specifications 323,115, [Class 1 (iii)], and 413,721 are referred to.ALSO:For use as a fungicide, copper oxychloride or a mixture thereof with basic sulphate of copper is oxidized, mixed with lime preferably in the form of calcium oxide, dried if necessary, neutralized by carbon dioxide, and mixed with an inert substance and/or a substance having high adhesive power such as dextrin.

Title: Defect detector circuit for inverter
Inventor: OOTA YASUMASA
IPC: H02M7/515
Filed: 1984-01-06
Abstract: PURPOSE:To detect a commutation failure by detecting the amplitude and the direction of a current of a common line by a set of current transformers and deciding the output signal of the transforming current by a sensor, thereby reducing the number of parts. CONSTITUTION:When thyristors 3a, 3b are simultaneously turned ON, a shortcircuiting circuit of an arm A1 is formed between a positive power source and a common circuit C, and a shortcircuiting current is flowed to the arm A1. This shortcircuiting current is detected by a current transformer 9, and judged by a sensor 10, thereby detecting the commutation failure of a thyristor. Since the shortcircuiting current is flowed through the transformer 9 even at the commutation failure time of a lower inverter, the commutation failure can be detected. Thus, the shortcircuiting current can be detected by the set of the transformers, the output signal of the current transformer is judged by the sensor. Accordingly, the number of parts can be reduced.

Title: Electromagnet device
Inventor: EBISAWA TSUNEO
IPC: H01F7/18
Filed: 1994-01-07
Abstract: PURPOSE:To compensate an electromagnet for a change in its attracting force due to a mounting angle by a method wherein a voltage which is divided from a power supply voltage and inputted into the negative input terminal of an operational amplifier is controlled corresponding to the mounting angle of an electromagnet device detected by a mounting angle detecting circuit to control a making coil current. CONSTITUTION:A mounting angle detecting circuit 24 composed of an angle sensor is provided, a voltage divided from a power supply voltage and controlled by a detection output of the mounting angle detecting circuit 24 is inputted into the negative input terminal of an operational amplifier 4. The divided voltage is controlled to increase to make a making coil current decrease, and on the contrary, if a mounting angle is larger than this angle or for increase an angle of 180 deg., the weight of a movable section serves to increase the force of a back spring to lessen an electromagnet in attracting force, and a power supply voltage is decreased by control to increase a making coil current. By this setup, an electromagnet cart be compensated for a change in its attracting force due to a mounting angle.

Title: Method for switching radio communication of movable radio communication system
Inventor: KOJIMA MUTSUMI
IPC: H04W36/36
Filed: 1988-01-06
Abstract: PURPOSE:To make the speed of the radio channel switching process of a movable radio communication system faster while the system is used for communication by making the inform signal sending timing to a control station faster as the movable station approaches a radio base station and causing the control station to select the base station which sends the inform signal at the fastest timing as the moving destination of the movable station. CONSTITUTION:A movable radio communication system is composed of a control station 1, radio base stations 2a-2c, and a movable station 6 and the control station 1 is connected with an exchange network. The radio base station 2a is constituted of a control station 3, a monitoring receiver 4, and transmitter-receivers 5-1-5-n. Each radio base station 2a-2c divides its own communication area in multiple stages and sets higher level values as approaching the center of the communication area. When the movable station 6 enters the communication areas of the base stations 2a-2c, the stations 2a/2c send inform signals to the control station 1 in such a way that the sending timing becomes faster as the movable 6 approaches the communication area of higher level values and the control station 1 connects the movable station 6 with the base station which sends the inform signal at the fastest timing for radio communication. Therefore, the switching process of radio channels can be made quickly while the system is used for communication.

Title: Method for forming mold
Inventor: UNOSAKI TSUNETO
IPC: B22C1/26
Filed: 1981-01-06
Abstract: PURPOSE: To reuse green sand without regenerating it and to improve the productivity by shortening the drying time, by filling a molding box with a mixed sand which is prepared by adding prescribed amounts of green sand, a water soluble paste, and water to silica sand, and then, by drying and hardening the mixed sand by dielectric heating.  
     CONSTITUTION: A molding sand is prepared by adding 100wt.pts. excess green sand in maxumum per 100wt.pts. silica sand. The molding sand is mixed with 1W5wt.pts. water soluble paste per 100wt.pts. sand, and 50W300wt.pts. water per 100pts. paste. The molding sand is fed to a molding box, then dried and hardened by irradiating high frequency wave or microwave. The reasons why the mixing ratio are specified is that, when more amount of green sand is mixed, the filling property in the molding box is deteriorated and the strength of the mold is lowered. When less amount of the water soluble paste is used, the strength is insufficient, and, when more amount of the paste is used, it is uneconomical. Moreover, when less amount of water is used, the paste does not show its adhesion effect, and, when more amount of water is used, the fulidity is deteriorated and longer drying time is required.
