Filed: 1990-10-23
Abstract: PURPOSE:To lower driving voltage necessary for discharge formation and reduce sputtering of the surface portion of a discharge electrode by making at least the surface portion opposed to a counter electrode into a thick film layer containing tungsten particles. CONSTITUTION:The surface portion opposite to at least a counter electrode C (an anode electrode 10) of a cathode electrode 22 is calibrated by a thick film layer 24 containing tungsten particles. For example, a cathode 22 is an electrode of a 2-layer construction made up of a distribution electrode layer 26 and the thick film layer 24 installed in order on a back plate 10. That is, the work function of tungsten is approx. 4.6eV and also the sputtering rate at the time when tungsten is sputtered with Ne ion of 100e V is approx. 0.038 atom/ion. It is thereby possible to lower a driving voltage and also reduce the sputtering of the surface portion of a discharge electrode.

Title: Manufacture of nb-ti multiple core superconducting wire
Inventor: SUZUKI HIDEMOTO
IPC: H01B12/10
Filed: 1989-10-31
Abstract: PURPOSE:To increase the critical current density in a weak magnetic field by keeping the temperature and time of heat treatment and the area reduction ratio in a cold wire drawing process after heat treatment within the respective fixed ranges. CONSTITUTION:After an area reduction process of a compound body having therein many Nb-Ti alloy filaments in a copper or copper alloy matrix, heat treatment is given at a temperature of 360-380 deg.C for 110-170 hours and then a cold wire drawing process is given at 85-95% area reduction ratio. Outside the above ranges of heat treatment and area reduction ratio, the critical current density of the wire in a weak magnetic field is 2700-5300A/mm<2> lower than normal. Since the wire easily disconnects in the case of a higher area reduction ratio and almost disconnects in the heat treatment of 380 deg.C for 100 hour or over and at the area reduction ratio of 85% or over, the treatment according to the invention prevents the disconnection of the wire.

Abstract: PURPOSE:To simplify the control program of a sounding period by storing a sounding start signal and a sounding stop signal of each digital sound signal in a pair of memory parts provided independently each other, respectively. CONSTITUTION:In a sound source data stored part 14V, various musical instrument sound source data of, for instance, a piano, a saxophone, cymbals, etc., are stored, and 8 pieces of selected sound source data are brought to time division by signal processing parts 20A - 20H and divided into 8 voices and 2 channels. Subsequently, a sounding start and a stop of each voice are controlled with switches S1a - S1h by using different flags, and with respect to 8 voices of A - H, an interpolation processing is performed by a pitch converting circuit 23. Next, when a switch S2a is closed by control data FMON from a terminal 35a, a reproducing sound is supplied to a terminal 34a, in which a sound signal is brought to frequency modulation (FM). Therefore, even if a modulating signal is of a super-low frequency of several hertz, a vibrato is applied to a signal to be modulated, and an FM sound source is obtained by a sampler system without providing special modulation exclusive sound source.

Title: Formation of thermally sprayed film of metallic chromium
Inventor: IWASAKI YOSHITAKA
IPC: C23C4/06
Filed: 1990-10-29
Abstract: PURPOSE:To obtain the thermally sprayed film good corrosion resistance and wear resistance without the problem of film peeling by using high-purity metal chromium powder, forming a thermally spraying combustion flame of a reduced flame of a specific temp. and specifying the particle flying speed of metal chromium. CONSTITUTION:The metal Cr powder having >=99% purity is used and the thermally spraying combustion flame temp. is specified to the temp. above the m.p. and below the b. p. of the metal Cr. In addition, the combustion flame is the reducing flame, and the metal Cr is thermally sprayed on the surface to be thermally sprayed at 2 to 3 Mach particle flying speed. The corrosion resistance is drastically degraded by the influence of the impurities (iron, etc.) if the purity of the metal Cr is below 99%. The remaining of the unmolten particles is prevented and the film performance is improved and stabilized of the thermally spraying combustion flame temp. is above the lower limit. The greater part of the metal Cr evaporates and the degraded thermal spraying efficiency and quality is resulted if the above-mentioned temp. is above the upper limit. The generation of Cr oxide is suppressed and the defectless film is formed by forming the combustion flame as the reducing flame. Both the adhesive strength and porosity are insufficient if the particle speed of the metal Cr is below the lower limit. The speed above the upper limit is not necessary in terms of the adhesive power for placticable use and low porosity.
