Title: Channel selecting device
Inventor: MURATA TOSHINORI
IPC: H03J5/02
Filed: 1979-07-14
Abstract: PURPOSE: To always ensure a steady and accurate channel selection, by giving attenuation to part of the peak point of the comb line characteristics of the comb line filter formed with the elastic surface wave element and then obtaining the first pulse at the peak point next to that mentioned above.  
     CONSTITUTION: The characteristics (a) of the comb line filter formed with elastic surface wave element 2A corresponds to the VHF low band and has the gentle attenuation characteristics even under peak point 146MHz at which the first pulse is  to be generated. Furthermore, the peak of 144MHz preceding the peak point of  146MHz is attenuated as shown by the dotted line and then taken out. The gentle  attenuation characteristics can be secured at both sides of the pass band becuase the  length is all identical for the portions crossing among input electrode 12 plus output  electrodes 13 and 14 each. And the peak value of 144MHz is attenuated owing to  the fact that the elastic surface waves having wavelength λ are all reflected by reflecting electrodes 15 and 16 to be prevented from reaching electrodes 13 and 14.  As a result, only the pulse equivalent to the peak point higher than 146MHz can be  obtained, thus preventing the malfunction which is caused by the variation of the  peak point.

Filed: 1986-04-17
Abstract: PURPOSE:To provide a wire to which CBN is firmly bonded, by charging the mixture of metal powder and cubic boron powder in a gap between a metal pipe and a metal rod inserted in the center part of the metal pipe, and by subjecting the pipe and the rod to heat treatment, cold drawing, polishing and pickling. CONSTITUTION:The mixture obtained by CBN particles having an averaged particle size of 150mum into pure Ni powder at a volume ratio of 13% is charged into a gap between a metal pipe and a metal rod having an outer diameter of 12mm and inserted into the metal pipe. Further the metal pipe is heated after it is welded to be sealed at both ends thereof, and then is subjected to four time repetitions of atmospheric cooling and cold-drawing to be reduced down to 1mm diameter. The above-mentioned process is one practical example in which charged Ni is metallically bonded to form a layer firmly carrying CBN particles. Thereafter, thus obtained product is dipped in a solution of hydrochloric acid to remove the part of the metal pipe at the outer peripheral section of the product. This CBN encrust wire may facilitate the cutting and grinding of iron group materials, and the cutting speed may be made to be high while the life of the CBN encrust wire is prolonged.

Filed: 1983-05-23
Abstract: PURPOSE:To provide an inexpensive nitrogen additive suitable for adding nitrogen to iron, steel, etc. by combining an alkali metal fluoride with lime nitrogen. CONSTITUTION:A nitrogen additive is obtd. by mixing 100pts. lime nitrogen having <=10mm. grain size and 2-10pts.wt. fluoride of an alkali metal. The fluoride of the alkali metal referred to here is enumerated by LiF, KF, NaF, Na2 SiF6, Na3AlF6, etc. and >=1 kind thereof can be compounded. If lime nitrogen is added to a molten iron or steel, the reaction of the formulas I , II is effected and the tensile strength of the steel or cast iron is increased but the effect thereof is not enough with the lime nitrogen alone. The above-described fluoride accelerates the reaction of the lime nitrogen and the substantial effect is obtainable by using the fluoride in conjunction with the lime nitrogen. The additive is also usable as a nitrogen additive to Al.

Title: Ultrasonic motor
IPC: H02N2/00
Filed: 1992-03-16
Abstract: PURPOSE:To obtain an ultrasonic motor which can produce traveling wave on a cylindrical surface by polarizing piezoelectric elements radially in the opposite directions between adjacent elements. CONSTITUTION:A piezoelectric element 1 is polarized radially into phase A and phase B with the minimum unit circumferential length of polarization being set equal to half the wavelength of traveling wave. Adjacent polarization units are polarized in the opposite directions and when a + polarization part is distorted radially outward, a - polarization part is distorted radially inward for same applying voltage. Since phase A and phase B are arranged while being shifted by a quarter wavelength of traveling wave in the circumferential direction, traveling waves are produced on both inner and outer circumferential faces of the piezoelectric element 1 upon application of AC voltages having 90 deg. phase difference for phase A and phase B. According to the constitution, a new type ultrasonic motor producing traveling waves on a cylindrical surface can be realized.

Accordingly, a torque variation is restricted and a stable set torque can be attained.
