Abstract: In the sound source system, the waveform sampled from the sounds of keys pressed down with two or more kinds of intensity are synthesized in a specified rate, thereby forming the waveform of the sounds of keys pressed down with the other kind of intensity. Thus, almost the actual instrumental deep sounds can be reproduced. The sound waveform sampled from weak key presses is passed through a low pass filter, and the filtered waveform composed only of low order harmonic components is transformed to weak press data in the pulse code modulation system for the storage. Similarly, the sound waveform sampled from strong key presses are passed through a high pass filter, thereby removing the low order harmonic components. The filtered waveform composed only of the high order harmonic components are transformed to strong press data in the pulse code modulation system for the storage. The high pass filter can remove the frequency components which pass through the low pass filter.

Abstract: A printing method to increase the printing speed of a dot printer. Before printing on the basis of the dot data representative of an original dot pattern showing fonts, graphics and the like, the original dot pattern is converted by converting M (M .gtoreq.3) dots successive in the line direction into N (M >N .gtoreq.2, M.noteq.2N) dots. Then, printing is performed on the basis of the thus converted dot data. In a modification, conversion is performed by converting each dot into n (n.gtoreq.2) successive intermediate dots in the line direction and when 2n or more intermediate dots are successive, selecting every m {(2n -1).gtoreq..sub.m .gtoreq.(n+1)}-th intermediate dot. In another modification, pattern conversion is effected by converting each dot into n (n.gtoreq.

Abstract: A thermal transfer recording and correction method, in which a thermal transfer ink layer is placed in contact with a transfer-receiving medium and is heated by heat generating elements of a thermal head in a pattern corresponding to a recording signal, is improved by preheating the ink layer. The ink layer, which is characterized by a transfer initiation temperature, is preheated by the thermal head which is heated by a preheating means. When a region of the ink layer is then further heated by the heat generating elements, the temperature of that region has a maximum and a minimum both within a range extending from the transfer initiation temperature to about 40.degree. C. higher than the transfer initiation temperature. Since the maximum and minimum temperatures are within a suppressed temperature range, an erroneous image can be more easily peeled off the transfer-receiving medium.

Abstract: Clock signals of the same phase are formed even when signal delays occur in clock signals transmitted on a clock line. In a clock synchronizing circuit which synchronizes circuit elements using clock signals taken from a common clock line, the clock line is bent midway into a pair of clock lines, and a center phase signal generating means generates a clock signal having a phase which is in the center of two clock signals of differing phase obtained from arbitrary points on the pair of clock lines which are at equal distances from the point at which the clock line is bent over. By using pairs of clock signals of differing phases taken at equal distances from the bend over point, three clock signals all having equal phase are obtained.

Abstract: A decompression data display device which calculates during a diver's dive the partial pressure of an inert gas in each of the tissues of the diver's body with the tissues having different half saturation times. The inert gas partial pressure of the inspired gas is compared with each of the partial pressures of the respective inert gases solved in the tissues to determine whether the inert gas is being discharged or absorbed. When the inert gas is being discharged, the respective inert gas partial pressure values in the tissues are calculated from an arithmetic expression different from an arithmetic expression used when the inert gas is being absorbed, and decompression data is obtained from the respective calculated inert gas partial pressure values in the tissues.
