Title: Electronic musical instrument
Inventor: UCHIYAMA SHIGERU
IPC: G10H1/053
Filed: 1992-10-14
Abstract: PURPOSE:To specify a pitch which accurately corresponds to an actual interval and to start generating a musical sound having the accurate pitch by correcting a pitch to the original pitch period by a pitch information correcting means only at the time of the rising of an input waveform signal when pitch informa tion is extracted from the input waveform signal. CONSTITUTION:Pitch extracting means 1 and 2 convert the input waveform signal which is previously obtained, into a digital signal, detect an effective peak value of the digital waveform and the zero-cross time right after it in order, and decide a pair of the effective peak value and zero-cross time right before or behind it to extract the pitch period. Then the pitch information correcting means 3 corrects only the pitch period which is detected by the pitch extracting circuit 1 and 2 for the 1st time by several percents. Then, a musical sound generating means 5 generates the musical sound having the pitch corresponding to the corrected pitch information at the time of the rising of the input waveform, but generates the musical sound with the pitch corresponding to the pitch information extracted by the pitch extracting means after the rising.

Title: Polymerization of propylene
Inventor: ASANUMA TADASHI
IPC: C08F4/64
Filed: 1985-12-11
Abstract: PURPOSE:To produce a polypropylene having stable quality at a constant rate of production, by controlling the charging amounts of an organic Al compound or a transition metal catalyst by adjusting the ratio of the organic Al compound to the transition metal catalyst. CONSTITUTION:Polypropylene is continuously produced by using a catalyst consisting of a transition metal catalyst (e.g. Ti halide supported on Mg halide) and an organic Al compound (e.g. trialkyl aluminum). In the above process, the production rate of polypropylene determined by generated heat quantity is controlled by the charging amount of the organic Al compound until the ratio of organic Al to the transition metal catalyst reaches a preset level and controlled by the charging amount of the transition metal catalyst thereafter. Preferably, the charging amount of organic Al is determined to keep the production rate of polypropylene at a constant level based on the measured production rate of polypropylene, the holdup volume of the organic Al calculated from the amount charged into a reactor and the predetermined relational formula between the production ratio of polypropylene and the holdup volume of organic Al.

Title: Fader controller
Inventor: ISHII TAKEHIKO
IPC: G05D3/12
Filed: 1991-10-24
Abstract: PURPOSE:To smooth the rotation of a motor, and to faithfully execute an instructed characteristic by detecting a voltage being proportional to the rotating speed of a fader, and feeding back this detected voltage to a motor driving circuit through a non-linear circuit. CONSTITUTION:By applying a voltage corresponding to the difference between the present position of contacts of variable resistors 25, 26 and a target value to be moved, a motor 24 connected to the contacts is rotated, and the variable resistors 25, 26 are moved to a target position. In this case, a speed sensor 11 generates an output voltage being proportional to the rotating speed of the motor 24. This output voltage is inputted to a subtracting circuit 13 through a non-linear circuit 12 for outputting a voltage being unproportional to the inputted voltage, and subjected to negative feedback. The subtracting circuit 13 subtracts an output voltage of the non-linear circuit 12 from a driving voltage of the motor 24. In such a way, in the case the rotating speed is high, the feedback amount is decreased, a high speed rotation is continued and a moving time is shortened, and in the case this rotation speed is low, this feedback amount increases and the rotation can be smoothed.

Title: Production of novolac resin
Inventor: SAKAMOTO HIDE
IPC: C08G8/10
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To obtain a novolac resin while markedly reducing the COD concentration of a waste water by reacting formalin having a methanol content in a specified range with a phenol. SOLUTION: In the production of a novolac resin, 37-38 wt.% formalin having a methanol content of 2-3 wt.% is used. The minimum storage temperature, namely, the lowest temperature necessary to prevent the deposition of a polymer, of the formalin is about 25 to 30 deg.C. Although this temperature is higher as compared with the minimum storage temperature i.e., 6-16 deg.C of common 37 wt.% formalin of a methanol content of about 7 to 12 wt.%, a simple heater suffices so far as the temperature is in such a range. Further, countermeasures against a formaldehyde vapor is not necessary. In virtue of the low methanol content, the COD of a waste water discharged in the production is reduced. Nevertheless, when it is lower than 2-3 wt.%, a polymer is apt to deposit, undesirably.

Title: Rubber composition
Inventor: TOMOKUNI HARUTAKA
IPC: C08K5/09
Filed: 1987-11-02
Abstract: PURPOSE:To obtain a rubber composition excellent in processability, cutting resistance and chipping resistance, by mixing a rubber composition with carbon black having a specified particle diameter, highly active silica and tung oil. CONSTITUTION:A rubber composition is prepared by mixing 100pts.wt. rubber with 35-50pts.wt. carbon black of an arithmetic mean particle diameter <=20nm as measured by an electron microscope, 5-20pts.wt. rubber-reinforcing, highly active silica and 1-15pts.wt. tung oil. Although the cutting resistance and chipping resistance can be improved by the addition of said carbon black, the processability is insufficient and therefore the practicality is poor by that addition only. Therefore, a softener is necessary and the addition of tung oil makes it possible to improve the processability and further the cutting resistance and chipping resistance.
