Title: Electronic musical instrument
Inventor: SUZUKI SATOSHI
IPC: G10H1/24
Filed: 1995-02-27
Abstract: PURPOSE: To set respective split points independently and not to change their array order as to a keyboard musical instrument whose keyboard can be divided into >=3 key key areas at >=2 split points. CONSTITUTION: An ABC split point (border between an ABC key area and a left key area) 52 and a LEFT split point (border between the left key area and a right key area) are set by operating an operation element such as a rotary encoder. The ABC split point 52 is so limited that it is never on the right side of the LEFT split point 53; and the LEFT split point 53 is so limited that it is never on the left side of the ABC split point 52. Therefore, when the ABC split point 52 moves to the right while the ABC split point 52 and LEFT split point overlap with each other as shown in a figure, the LEFT split point 53 also moves to the right accordingly. Further, when the LEFT split point 53 moves to the left, the ABC split point 52 also moves to the left correspondingly.

Filed: 1995-02-27
Abstract: PURPOSE: To obtain an AIDS vaccine, having high safety, capable of inducing strong liquidity and cellular immunity for various HIV variant strains and having high preventing effects by binding a specific peptide to respective branches of a branched lysine oligomer. CONSTITUTION: This vaccine contains a V3 region of a gp120 in an HIV envelope and is obtained by binding a peptide of the V3 region and a peptide without containing the region (e.g. a peptide in an inner protein Gag region of HIV) to respective branches of a nuclear substance comprising a branched lysine oligomer. For example, HIV-1-IIIB type and HIV-1-ThaiA are cited as the peptide in the V3 region; however, a peptide synthesized with an automatic peptide synthesizer, etc., is preferred.

Abstract: PURPOSE:To form a thin superconducting film into which the impurities from a base are less incorporated and which has good crystallinity by heating the band shaped region of the thin oxide superconducting film formed on the base and moving the heating region from one end to the other end of the thin film. CONSTITUTION:The thin oxide superconducting film 1 is formed by a sputtering method, etc., on the base 2. The thin superconducting film consisting of, for example, an oxide contg. Cu and more particularly the film consisting of Y, Ba, Cu, O, etc., are used. The band-shaped region including one width of the above-mentioned thin film 1 is heated upon formation of said film and this heating region 3 is moved in one direction like an arrow 6 from one end to the other end of the thin film 1. This heating is preferably executed in an oxygen atmosphere and is executable by irradiation of IR rays, light, etc., or high- frequency induction heating, etc. The unheated region 5 is thereby successively heated so that the heated region 4 is formed over the entire region of the thin film 1. The crystallinity of the above-mentioned thin film 1 is thereby improved and the incorporation of the impurities from the base 2 into the thin film is decreased. The good-quality thin superconducting film is thus formed.

Filed: 1982-03-12
Abstract: PURPOSE:To obtain the natural recording/reproducing characteristics on the entire recording surface, by superposing a 2-dimensional signal having alternating polarities on a density input signal which is used for recording a variable-density picture, then using this superposed signal to a picture recording output signal. CONSTITUTION:A pseudo random number generator 1 generates a positive random number 11 synchronously with an X-direction picture element clock 14. The number 11 is added to an adder/subtractor 2 together with a density input signal 10. While the clock 14 and a Y-direction line feed signal 15 are applied to an exclusive OR circuit via FF3 and 4 respectively to produce a polarity signal 16 to both (x) and (y) respectively. The signal 16 functions to perform the addition and subtraction alternately through the adder/subtractor 2. Thus the adder/subtractor 2 gives addition and subtraction of the number 11 alternately to the signal 10 in response to the signal 16. As a result, a picture output signal is obtained by adding a polarity alternating random number signal to the signal 10 for the output 13 of the adder/subtractor 2.
