Title: Differential signal detecting circuit
Inventor: KITANO JIYUNJIROU
IPC: H04M19/00
Filed: 1983-03-04
Abstract: PURPOSE:To realize a monolithic IC constitution of a subscriber's circuit at a low cost by constituting a titled circuit so that only a differential signal is detected from two differential signal outputs, and the same phase noise signal is suppressed. CONSTITUTION:A two-wire differential signal current generated from a subscriber's terminal 3 flows through current mirrors 12, 13 as indicated with a full line arrow id, and an output current of the mirror 12 is current-inverted by a current mirror 14, and flows through a resistance 18 and a transistor TR17. An output current of the mirror 13 flows to a resistance 16 and a TR15. In this case, in case when resistance values of the resistances 16, 18 are made equal to each other, if the same phase noise current indicated with a dotted line ic is generated in a line resistance 4, the same phase current component inputted to the mirror 12 becomes an opposite direction, therefore, the same phase component is not generated in an output terminal 19. In the same way the same phase noise current is not generated in an output terminal 20. That is to say, only a differential signal is detected from the terminals 19, 20, and the same phase noise signal is suppressed. According to this circuit configuration, it is unnecessary to use a high resistance in order to reduce the power consumption, and an IC constitution is executed easily.

Filed: 1989-02-16
Abstract: PURPOSE:To enlarge the degree of spot position adjustment and deflection sensitiveness adjustment for a fluorescent screen by partly adding coils wound in the reverse direction to coils wound in normal direction. CONSTITUTION:A pair of bosses 4a, 4b symmetric to each other are formed in winding ways of yokes 1a, 1b, and inverse direction coils 6a, 6b are formed in the middle of normal direction coils 5a, 5b consisting of a wire 2 wound in one direction as shown by an arrow A using the pair of bosses 4a, 4b. Normal direction magnetic fields 7a, 7b and reverse direction magnetic fields 8a-8d are thus generated by the normal direction coils 5a, 5b and inverse direction coils 6a, 6b respectively. Distribution of the magnetic fields by deflection coils 3a, 3b and the yokes 1a, 1b is thus synthesized by these magnetic fields. Position adjustment and deflection sensitiveness adjustment for a spot in a fluorescent screen which cannot be achieved by the normal direction magnetic fields only can thus be achieved.

Title: Ultrasonic treatment process for diluted alcohol solution
Inventor: HIROSE MASANAO
IPC: C12H6/02
Filed: 1982-03-08
Abstract: PURPOSE:To vaporize an alcohol from a diluted alcohol solution in high efficiency, and to reduce energy consumption, by making an oscillating member arranged in a diluted alcohol solution vibrate ultrasonically so that cavitation is produced. CONSTITUTION:Methyl alcohol, ethyl alcohol, propyl alcohol, etc. can be used as the diluted alcohol solution 91 put in the interior of the ultrasonic treatment device 16. Cavitation is produced by making the oscillating member 20 vibrate ultrasonically in an extremely slight degree in a state wherein the pressure in the ultrasonic treatment device 16 is reduced transiently at the early stage, so that the alcohol in the solution 91 is vaporized. Once the cavitation is produced, so-called toxicosis takes place, the inner pressure is raised by the vaporization of gradually vaporized alcohol, so that the cavitation is continued. When the cavitation is produced, the solution 91 is made to flow in such a way that it is jetted upward above the oscillating member 20 by the vaporization of the alcohol. The vaporized alcohol is sent through the pipe 27 connected to the top part of the container 17.

Title: Focus detecting system
Inventor: YOSHIDA MASAHITO
IPC: G03B3/00
Filed: 1979-03-27
Abstract: PURPOSE: To improve the accuracy and reliability of focus detection by providing plural ways of analysis system.  
     CONSTITUTION: m Ways of filter functions are stored in the memory 6 connected to a CPU5. After the outputs of the photo detector array 2 which receives the subject light through a photographing lens 1 or the like are digitized by an A/D converter 4, they are taken in a CPU5, where they are subjected to Fourier transformation to obtain power spectra, after which m ways of filter functions are multipled to the power spectrum from the 1st one and the results are added to determine the evaluation value by the j-th filter function. The significance of this evaluation value is judged by depending upon whether this value is above a certain threshold value or not. When it is judged to be significant, the evaluations by the (j+1)th order having higher weights at higher frequencies are done up to the maximum m times and when all are judged to be significant, j is made m. On the other hand, when they are judged to be not significant, 1 is deducted from j and the evaluation value of the previous time and the new evaluation value are compared, whereby the operation of the photographing lens 1 is accomplished.

Abstract: PURPOSE:To speed up the rising of a thermoelectromotive force generated by a heat sensitive part and to improve a reliability on an operation, by a metod wherein a flame guide path is mounted in an installation space for a pilot burner, and a heat-sensitive part in a safety device is positioned at a given angle to said path. CONSTITUTION:A gas burner consists of a main burner 1, a premixture part for an outer combustion cylinder, combustion parts 2, 3 a premixture part for inner combustion cylinder, combustion parts 4, 5, and a pilot burner 6 for ignition. After flame, produced resulting from the ignition of the pilot burner 6, collapses with the premixture part 2, it goes upward and passes through a flame guide path 11, in which a gap between the combustion part 3 and a glass cylinder rest 10 is partially windened, to heat a heat-sensitive part 12 for a safety device. The heat-sensitive part 12 is mounted at an proper angle to the path 11 so that flame is reduced in the passage resistance and is prevented from the spreading. Additionally, a hot contact side 16 is increased more in a temperature rising ratio than that of a cold contact side, and thereby the thermoelectromotive force can be generated in a short time.

Title: Automatic tuning device
Inventor: MATSUDA TOSHIO
IPC: H03J7/18
Filed: 1987-02-18
Abstract: PURPOSE:To attain a step speed with an optimum search to its reception band by constituting the search cycle by a wait time and a PLL lock detection time and revising the wait time in response to number of channel selection of received bands. CONSTITUTION:In depressing a search button (up-button) 21, a search means 201 drives an N-value conversion means 202 to start an N-value supply means 203 and the N-value receiving in each band at a prescribed frequency interval is sent to a variable frequency divider circuit 13. In depressing the button 21, the N value to obtain a local oscillation frequency to increase the reception frequency is read sequentially. The search cycle is set to one N value, the wait time is provided at first and the lock detection time is set. The wait time is revised in response to the band and since the time is comparatively short in the AM/FM and number of stations is less in the TV frequency, the time is set comparatively longer. When locking is detected, the muting of the received output is released.
