Filed: 1986-12-19
Abstract: PURPOSE:To obtain a desired multiplied wave output and to require no filter for removing an unnecessary frequency component by generating a power multiplying wave string for sequentially increasing a power multiplier for every square from a fundamental wave input, weighting so as to erase a low order power multiplying wave and synthesizing respective power multiplying wave output. CONSTITUTION:A power multiplying wave generating circuit 1, a coefficient circuit 2 and an adder circuit 3 are provided. The power multiplying wave generating circuit 1 executes the operation of a power multiplying with respect to the fundamental wave input. A maximum order is 2n or 2n-1. It respectively generates the power multiplying waves of the multiplier to be increased sequentially for every square. The coefficient circuit 2 weights respectively to the respective power multiplying wave outputs of the power multiplying wave generating circuit 1 to generate an output. The adder circuit 3 synthesizes the respective outputs of the coefficient circuit 2 to generate the output. Thereby, 2n or 2n-$1 multiplied wave as a synthesized output is obtained and a band-pass filter for removing the unnecessary wave component is not required to an output side.

Inventor: IGUCHI YUJI
IPC: B32B7/06
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a threefold post card from which a strongly bonded face can be release again. SOLUTION: In a threefold post card folded into the Z-shape and pressure bonded, the surface alyer release strength of a substrate is larger than the bonding strength of a re-releasing face, and smaller than the bonding strength of a strongly bonded face as an opposite face of the re-releasing face. A substrate manufactured by using a twin wire type paper making machine is more preferable. When the strongly bonded face is released, the sheet surface is securely protected from being broken, and it is impossible to write an information on the strongly bonded face by the arrangement. Also the sheet surface is not at all broken when the re-releasing face as an information written face is released.

Title: Cardiac pacemaker
Inventor: SHOJU MAKOTO
IPC: A61N1/375
Filed: 1987-12-04
Abstract: PURPOSE:To prevent the loosing of functions of a cardiac pacemaker caused by the magnetic shielding effect and magnetic sensitive effect, by covering its functional portion thereof with an oxide superconductive material. CONSTITUTION:In the outside circumference of the functional portion of a cardiac pacemaker, a shielding cover 2 made of oxide super conductive material is installed and further a protecting cover 3 made of materials harmless to human body is installed outside of it. When magnetism is weak, weak magnetism is shielded by the Meissner effect possessed by the shielding cover 2, giving no unfavourable effect on the functional portion. In the presence of strong magnetism, the user can feed the repelling force with respect to the magnetism generated by the Meissner effect of the shielding cover 2, because the pacemaker is embedded in the body. Therefore, the user can retreat to a safe place before the magnetism exceeds a critical magnetic field value.

Filed: 1988-12-05
Abstract: PURPOSE:To safely prevent rice blast while reducing labor by carrying out smoking treatment of rice seedlings during the seedling period in a house using a smoking agent containing 4,5,6,7-tetrachlorophthalide. CONSTITUTION:The subject smoking agent containing 4,5,6,7-tetrachlorophthalide as the active component is prepared and used for smoking treatment in a greenhouse to prevent blast of rice seedlings during the seedling period. In comparison with the spraying method using a wettable powder or a dust containing the above-mentioned active component, a higher effect of protection of rice blast is attained and the pesticide treatment can be carried out in a short time. This smoking method has also such a merit that a person applying the pesticide is not bathed with the pesticide at all. In preparation of the pesticide, an urea nitrateguanidine salt, perchlorate, etc., is used as a heating material and woodflour, cellulose, etc., is used as a regulating material of combustion as necessary. The application amount is preferably 1-1000mg per 1m<3> in the house as the active component.
