Title: New milk magnesium/calcium material and its production
Inventor: SHIGEMATSU AKINORI
IPC: A23C9/152
Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To obtain the subject material useful for simply and efficiently preventing osteoporosis, etc., by passing a milk through a weakly acidic cation exchange resin and a strongly acidic cation exchange resin, eluting adsorbed magnesium, etc., and recovering as a magnesium/calcium salt. SOLUTION: A milk such as cheese whey is successively passed through a weakly acidic and a strongly acidic cation exchange resins. Magnesium and calcium adsorbed on the strongly acidic cation exchange resin are eluted and recovered as a magnesium/calcium salt to give a milk magnesium/calcium material having >=13 wt.% magnesium and calcium content in the whole solid in which the magnesium/calcium salt does not form a clear crystal structure. Preferably a solution containing the eluted magnesium and calcium is adjusted to pH 6.0-7.0 and the magnesium/calcium salt is recovered as precipitate, the recovered magnesium/calcium salt is suspended in water and further purified by membrane separation or centrifugal separation.

Title: Method for driving ultrasonic motor
Inventor: TERATANI AKIRA
IPC: H02N2/00
Filed: 1992-12-10
Abstract: PURPOSE:To improve drive efficiency by making a phase difference between electric signals variable, and by setting the phase difference to a value more than 90 degrees in a ultrasonic motor in which a rotor is driven by providing electric signals, which have the same drive frequency but differ from each other in phase, to two electrodes formed on a piezoelectric element. CONSTITUTION:With respect to an ultrasonic motor M that rotates a rotor by vibration of piezoelectric ceramic, a driving device is made up of a CPU 1, an oscillator 2, a shift register 3, data selectors 4 and 5, a filter 6, and a driver 7. To cope with a drop in driving torque of the piezoelectric ceramic having a small diameter, a phase difference control signal 'c' is provided to the data selector 4, and a phase difference between a signal 'd' and a signal 'e' which are inputted to the data selector 5 is changed to a value more than 90 degrees.

Title: Device and method for converting speech, and computer- readable recording medium recorded with speech conversion program
Inventor: YAMANE ATSUSHI
IPC: G10L21/04
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to obtain a good speech at around 6 kbps-16 kbps pitch rates and also freely change the speech in pitch. SOLUTION: After an inputted analog speech waveform has been converted into a digital speech signal by an A/D conversion part 12, a speech encoding part 14 encodes the signal by CELP(Code Excited Linear Prediction coefficient) encoding system, and pitch information extracted during this encoding processing is sent also to a pitch conversion part 16 of the following stage. When a device user inputs a desired pitch conversion magnification, pitch information inputted is conversion-processed accordingly. A speech decoding part 18 executes decoding processing by the CELP system by using the pitch information converted by the pitch conversion part 16 and the information extracted and encoded by the pitch encoding part 14, and decodes the encoded digital speech signal.  A D/A conversion part 20 converts the digital speech signal decoded by the speech decoding part 18 into an analog speech signal.
