Title: Method for collecting krill phospholipid and functional food and nerve function improving agent having nerve function improving effect
Inventor: MARUYAMA KAZUTERU
IPC: A23L17/40
Filed: 1989-02-14
Abstract: PURPOSE:To obtain an useful phospholipid in high purity by fractionating an ethanol extracted total lipid of fresh krill dehydrated by vacuum freeze drying method to specific two ingredients using an absorption column chromatography and further isolating these ingredients using a fraction collector. CONSTITUTION:A fresh krill is dehydrated to <=6% water content using a vacuum freeze drying method. Then the dried krill is homogenized with ethanol to extract total lipid. The ethanol is removed as much as possible from the total lipid and the extracted total lipid ia fractionated to soluble fraction and insoluble fraction using an acetone based solvent or hexane based solvent as eluate and then the solvent is cleaned from the insoluble fraction to give a crude phospholipid. Then the crude phospholipid is fractionated to phosphatidyl choline and phosphatidyl ethanolamine with an absorption column chromatography using ethanol based solvent, acetone based solvent or hexane based solvent as an eluate. Then each phospholipid ingredient is isolated therefrom in a high purity of about 90-95% by a fraction collector.

Title: Pressure sensor
Inventor: OKUMA SHIGEO
IPC: G01L9/08
Filed: 1991-02-05
Abstract: PURPOSE:To enable a pressure to be detected highly accurately by preventing a temperature change of a piezo-electric element and a superposition of a pyroelectricity onto a voltage signal. CONSTITUTION:A temperature switch 13 is connected to a heater 11 in series via a lead wire 12 and is formed by a PTC (positive property) type thermistor where its resistance value rapidly changes at the Curie temperature. Also, the Curie temperature of the temperature switch 13 is adjusted to a setting temperature T which is set approximately 5-6 deg.C higher than an average temperature of a piezo-electric body 9 in a constant combustion status within a combustion chamber. The temperature of temperature switch 13 is increased along with that of the piezo-electric body 9 via an upper plate 10. When that temperature reaches the setting temperature T. a current which is fed from a battery to the heater 11 is blocked by increasing the resistance value. thus enabling a heat build-up of the heater 11 to be stopped. Also, when the temperature of the piezo-electric body is decreased below the setting temperature T, the resistance value is reduced for allowing a current from the battery to be fed to the heater 11, thus enabling the piezo-electric body 9 to be retained to the setting temperature T owing to the heat build-up of the heater 11.

Abstract: PURPOSE:To perform the excitation smoothly during a speed increase from the finish of synchronization at a half speed to a rated speed, by controlling a field voltage set point by the output from a field current control circuit after the finish of synchronization in the neighbourhood of a half speed of the first and second synchronous generators. CONSTITUTION:In a biaxial synchronization of a primary machine 1P and a secondary machine 1S, a field circuit breaker 41 and an electromagnetic contactor 31 are closed to give initial excitation to generators. On this occasion, thyristors 2P and 2S are gate-blocked. When the biaxial synchronization is finished, the gate block is cancelled.

Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To improve the data transmission efficiency of a multicarrier transmission system and to prevent the power loss of the system by setting the power of each subchannel proportionally to an SNR value. SOLUTION: A multicarrier transmission system is constituted of a carrier transmitting section 600 and a power control section 602 and the section 600 is constituted of a carrier transmitter 700, a transmission channel 702, and a carrier receiver 704. The power control section 602 is constituted of an SNR calculating section 706, a primary power deciding section 708, a secondary power deciding section 710, and a power adjusting section 712. The SNR calculating section 706 finds an SNR by dividing the sensitivity of signals by the sensitivity of noise after calculating the sensitivity of noise by every subchannel upon receiving data signals.  The primary power deciding section 708 decides the transmission power value of each subchannel proportionally to the SNR value of each subchannel found by means of the calculating section 706 and assigns the power values for transmitting information by each subchannel. At the time of assigning the power values, a larger power value is assigned to a subchannel having a higher SNR.

Title: Demodulator
Inventor: UCHINO SEIJI
IPC: H04B7/26
Filed: 1991-03-01
Abstract: PURPOSE:To demodulate an input signal correctly even when an amplitude of the input signal is largely fluctuated by employing an A/D converter through the use of the mu rule quantization rules and to make the demodulator small in size and light in weight by forming the demodulator with digital circuit components. CONSTITUTION:Analog input signals I,Q are converted into digital input signals by each A/D converter 31. The A/D converter 31 consists of an ununiform quantization employing the mu rule quantization rules. That is, the A/D converter 31 transforms an input value into a logarithmic value to output an argument. Thus, even when a signal level of the input signal is changed considerably, number of digits of the argument to be outputted is unchanged. As a result, even when the amplitude of the input signals I,Q is fluctuated due to fading or the like, the outputted digital signals XI,XQ are not largely changed. Thus, a complex declination phi a reproduction symbol K, a phase error gammae a square mean value xsi and an amplitude (y) are calculated with prescribed accuracy by using the digital signals XI, XQ.
