Title: Liquid crystal display device
Inventor: HOSHIYA TAKAYUKI
IPC: G09G3/36
Filed: 1988-11-02
Abstract: PURPOSE:To find the best display conditions for display picture elements and to drive a liquid crystal panel by providing picture elements for monitoring which can be driven independently of the display picture elements outside the display area of the liquid crystal panel and measuring the characteristics. CONSTITUTION:The picture elements 5 for monitoring which enable the reference level of a data voltage to be adjusted independently are provided outside the display area of the liquid crystal display panel 1 and a brightness measuring means 6 measures the brightness of the picture elements 5 for monitoring. Namely, when the liquid crystal panel 1 is in operation, an adaptive driving means 7 varies the reference level of a data voltage to thin film transistors TFT constituting the picture elements 5 for monitoring and the brightness measuring means 6 measures variation in the brightness of the picture elements 5 for monitoring based upon above variation. Then, when the adaptive driving means 7 detects the reference level with which the brightness of the picture elements 5 for monitoring are maximum, this adaptive driving means 7 sets the reference level in a reference level varying means 4. Consequently, the best display conditions for the liquid crystal cells for display are found to drive the liquid crystal panel.

Title: Restorer radio repeater station
Inventor: AONO YOSHITAMI
IPC: H04B1/74
Filed: 1992-10-15
Abstract: PURPOSE:To add an error correcting function to a radio repeater station which applies a restorer system when the faulty one of working circuit of a digital multiplex radio system is switched to a stand-by circuit. CONSTITUTION:An error correcting decoder 2 corrects the error of the demodulated signal received from a demodulator 1 and decodes the signal. Then a frame step-out is detected and a random restorer pseudo synchronizing signal sent from a PN signal generator 3 is selected. An error correcting coder 5 corrects the error of the preceding pseudo synchronizing signal, and this synchronizing signal is modulated by a modulator 6 and sent to the next radio section. Instead of the random restorer pseudo synchronizing signal, a restorer pseudo synchronizing signal is acquired by applying the signal processing to the minimum word that is previously stored so as to reduce the correlation of data. This new pseudo synchronizing signal is switched from the signal which is corrected again by the coder 2 and then coder 5 and then modulated. This modulated signal is sent to the next radio section.

Abstract: PURPOSE:To prevent the occurrence of the hunting of a motor caused by the phase lead of a rotor by forming a pair of stator chambers by putting the first and second stators together in such a state that their magnetic poles face the clearances of the magnetic poles of the opposite stators and omitting magnetic poles front the closely facing sections of rotors mounted in the stator chambers. CONSTITUTION:The first and second stators 1 and 16 are put together in such a state that their magnetic poles 3 and 18 face the clearances of the magnetic poles of the opposite stators. As a result, a pair of stator chambers 27 and 28 is formed of magnetic poles arranged in hollow sections 10 and 10'. Rotors 29 and 30 are respectively put on rotor shafts 4 and 5 in rotatable states and housed in the stator chambers 27 and 28. The rotors 29 and 30 are constituted so that their closely facing sections can magnetically act to each other by omitting one piece of the magnetic poles 3 and 8 from the closely facing sections and forming empty sections. Therefore, smooth rotation can be obtained from this motor even when the voltage across the stator coil becomes excessively high, because the occurrence of the hunting caused by a phase lead can be prevented.

Title: Digital signal detection system
Inventor: NAKAMURA SEIZO
IPC: H04L7/027
Filed: 1988-11-04
Abstract: PURPOSE:To surely detect the presence of a digital signal by setting a reference voltage of an analog comparator in advance properly. CONSTITUTION:A radio wave subject to frequency modulation (FSK) by a digital signal is caught by a reception antenna 1, frequency-detected and a digital signal is outputted from a data output terminal 11. A pulse outputted from a change point detection circuit 16 passes through a band pass filter 17 whose band width is sufficiently narrow, its envelope is detected by an envelope detector 122, and after the AC component is eliminated by a low pass filter 13, the result is compared with a reference level by an analog comparator 14 and when the level is discriminated to be larger than the reference level, a signal detection output representing the presence of the digital signal is outputted at a signal detection output terminal 15. On the other hand, when no radio wave comes to the reception antenna 1, no digital signal is outputted from an analog comparator 10 and only random noise is outputted. Thus, a signal detection output representing the presence of a digital signal is not outputted from the analog comparator 14.

Title: Piezoelectric element driving unit
Inventor: SUZUKI MASASHI
IPC: H01L41/08
Filed: 1986-11-20
Abstract: PURPOSE:To improve the power efficiency of a piezoelectric element, by providing a converter controller for controlling a DC-DC converter to apply a predetermined voltage between terminals when the piezoelectric element is charged, while turning a second switching element ON when the piezoelectric element is discharged, and turning said switching element OFF when the terminal voltage becomes approximately 0 volt. CONSTITUTION:When a high voltage is applied onto a piezoelectric element 2 so as to drive said element 2, a switching element 31 in a DC-DC converter A is driven and the terminal voltage of the piezoelectric element is controlled to a predetermined level. When the piezoelectric element 2 is discharged after driving, and recovered to the original state, a second switching element 32 in a bilateral DC-DC converter A for regenerating power from the piezoelectric element A to a DC power source is turned ON, and when the terminal voltage of the piezoelectric element A reaches to approximately 0 volt, the second switching element 32 is turned OFF. Consequently, electrostatic energy being charged in the piezoelectric element when it is driven is regenerated to the power source 1 through utilization of resonance.

Title: Fixing device
Inventor: NAKAJIMA EIJI
IPC: G05D23/24
Filed: 1989-10-24
Abstract: PURPOSE:To suppress damage caused by toner sticking to a temperature sensor and to prolong the service life of a pressing and heating part by driving at least a second temperature sensor by a driving means so that the sensor is moved to or away from the pressing and heating part. CONSTITUTION:The temperature of the pressing and heating part is controlled based on temperature measurement by a first temperature sensor 34 and the second temperature sensor 35. When the temperature of the pressing and heating part is low, the driving means moves the second temperature sensor 35 away from the pressing and heating part. Consequently, the damage of the pressing and heating part of the toner firmly sticking to the sensor 35 is suppressed. When the pressing and heating part is sufficiently heated to a high temperature, the driving means brings the second temperature sensor 35 into contact with the pressing and heating part. Since the pressing and heating part has already reached a high temperature at this time, the toner firmly sticking to the second temperature sensor 35 is speedily fused, thereby suppressing the damage of the pressing and heating part. Thus the service life of the pressing and heating part is prolonged.
