Title: Temperature controller
Inventor: SANAKA YOUZOU
IPC: G05D23/20
Filed: 1979-09-14
Abstract: PURPOSE: To easily control the temperature at a predetermined value repeatedly and thereby improve the operation of the temperature controller for use with a dryer in which hot air is used by making use of a digital setting circuit which selects resistance values corresponding to desired temperatures of the hot air.  
     CONSTITUTION: In a temperature controller, a difference between the signal outputted from the setting circuit 8 and the signal outputted from a temperature detector 2 which detects the temperature of hot air is obtained by a differential amplifier 3. The output signal from the differential amplifier 3 is converted by a voltage- current converter 4 and a current-frequency converter 5 into a pulse signal. The  pulse signal triggers a monostable multivibrator 6. The multivibrator 6 outputs a  pulse signal to actuate an electromagnetic pump 7 for a preset time period so that liquid fuel is supplied to a burner bot shown in the drawing. The setting circuit 8 includes a digital setting device which selects one of a plurality of resistors RR1 to  RR4 by its corresponding one of a plurality switches SW1 to SW4. The resistance  value of the resistors RR1 to RR4 is respectively determined corresponding to four different hot air temperatures.

Title: System for switching spare device
Inventor: TAKAHASHI AKIHIKO
IPC: H04B1/74
Filed: 1987-05-14
Abstract: PURPOSE:To rapidly recover a transmission line even when a fault without issuing alarm is generated at a transmission terminal, by transmitting and switching information representing the fact of the generation of abnormality in both reception signals current in use and spare from a reception terminal to the transmission terminal with an inverse line. CONSTITUTION:When the abnormality is generated in a transmission signal due to the fault of a modulation part 4 current in use, a monitoring circuit 16 detects the fact of the generation of the abnormality in both signals current in use and spare at the reception terminal. The monitoring circuit 16, in the case of detecting the continuance of the abnormality of the signal exceeding a prescribed time, transmits the information of the fact from a transmitter 17 to a receiver 18 via the inverse line. A control circuit 19 allows a switch 7 to switch connection to a transmission part 5 on a spare side by controlling the switch 7 corresponding to the above operation. Consequently, the transmission terminal begins to transmit the transmission signal without the abnormality outputted from the transmission part 5 on the spare side to the reception terminal.

Title: Digital stereophonic audio compression system
Inventor: IMAI SUSUMU
IPC: H04H1/00
Filed: 1991-04-24
Abstract: PURPOSE:To apply data compression to a digital stereo audio signal with a high efficiency without deteriorating sound quality. CONSTITUTION:A digitized left channel signal L is fed to a difference circuit 3 and its output signal is given to an optimized vector quantizer 4, in which the signal is subjected to vector quatization. Thus, the left channel signal L is subjected to data compression at a high compression rate without deterioration in sound quality. A digitized right channel signal R with high correlation with the left channel signal L is fed to the difference circuit 3 from an input terminal 2, in which a difference signal D with the left channel signal L is formed and the difference signal D is subjected to vector quantization at a vector quantizer 5. Since the amplitude of the difference signal D is small, the number of representative vectors in the vector quantizer 5 is reduced and then a data quantity of the output of the vector quantizer 5 is made smaller than the data quantity of the output of the vector quantizer 4.

Title: Driving method for liquid crystal display device
Inventor: NAKAGAWA SATORU
IPC: G02F1/133
Filed: 1989-05-12
Abstract: PURPOSE:To minimize a driving frequency difference and to reduce the uneveness of display by driving a liquid crystal with such a vertical synchronizing signal as the number obtained by dividing a vertical synchronizing signal period by a period for selecting one scanning signal line becomes larger than the number (n) of scanning signal lines, and also, inverting the polarity of an applied voltage, whenever (l) pieces of scanning signal lines of a natural number being smaller than (m) are selected. CONSTITUTION:The number obtained by dividing a vertical synchronizing signal period by a period for selecting one scanning signal line is denoted as (m) and a natural number being the same as (m) or smaller than (m) is denoted as (l) and the least common multiple of (m) and (l) is denoted as H. In this state, when H/l becomes an odd number, the polarity of an applied voltage to a liquid crystal display element is inverted, whenever (l) pieces of scanning signal lines are selected. Also, when H/l becomes an even number, the polarity of the applied voltage to the liquid crystal display element is inverted, whenever (l) pieces of scanning signal lines are selected, and moreover, this polarity is inverted at every vertical synchronizing signal period. In such a manner the frequency difference of the applied voltage to the liquid crystal display element generated by a display pattern is minimized and the uneveness of the display is reduced.
