Title: Frequency characteristic correction circuit
Inventor: NAKATANI TOMOFUMI
IPC: H03G5/02
Filed: 1984-07-31
Abstract: PURPOSE:To suppress the phase difference at an intermediate frequency to a small value by varying interlockingly a time constant comprising a resistor and a capacitor connected between an input/output terminal of a negative feedback amplifier with the amplification factor of the negative feedback amplifier. CONSTITUTION:An input signal applied to an input terminal 11 is branched into two; one is applied to an inverting input terminal 16 of a broad band amplifier 14 via a resistor 12 and the other is applied to an output terminal 15 via a variable resistor 18. The non-inverting input terminal of the amplifier 14 is grounded, the output is branched into two; one is applied to the output terminal 15 via a capacitor 19 and the other is fed back negatively to a terminal 16 via a variable resistor 13. The resistors 13, 18 are varied interlockingly. The gain is changed by varying the resistor 13 and the resistor 18 is changed at the same time, the time constant comprising the resistor 18 and the capacitor 19 is changed, the phase difference between low and high frequencies is zero, while the phase difference even at the intermediate frequency is decreased.

Title: Horizontal afc circuit
Inventor: KAWAHARA TSUKASA
IPC: H04N5/12
Filed: 1982-09-17
Abstract: PURPOSE:To control accurately the oscillating pulse frequency, by converting a horizontal oscillating pulse into a rectangular wave and operating a horizontal AFC circuit, in a horizontal AFC circuit used for a video signal discriminating circuit. CONSTITUTION:A sawtooth wave produced at a horizontal oscillation input terminal 13 is applied to a base of a transistor (TR) 34. In applying a DC potential V37 to a base of a TR 35, a rectangular wave is outputted at a collector of the TR 35, applied to a base of a TR 4, and when the voltage is lower than the base voltage of a TR 5, the TR 5 is turned on. Thus, when a positive pulse horizontal synchronizing signal is applied from an input terminal 1, a TR 2 turns on to draw a current from the TRs 4, 5 and a horizontal oscillating pulse signal matched to the horizontal synchronizing signal is obtained.

Title: Integrator for illuminance
Inventor: TSUKAMOTO KAZUYOSHI
IPC: G01J1/42
Filed: 1979-12-13
Abstract: PURPOSE:To enhance the reliability of the device by making compensation with the reverse output of the 2nd amplifier in the case when offset voltage falls due to the drift of the 1st amplifier and thereby undesired discharge is made. CONSTITUTION:In the case when input turns zero in the nighttime or due to any other reasons and the output v1 of the amplifier Ic1 falls below the voltage of a potential memorizing element MD due to the drift, the potential memorizing element MD makes discharge through the intermediary of a resistance R2. When the voltage of the element MD turns negative through this discharge, the voltage of the output v2 of the amplifier Ic2 becomes positive and it charges the potential memorizing element MD through the intermediary of a resistance R7 from the point of time when the voltage thereof exceeds the forward voltage of a diode D. Thus, the voltage does not fall below the voltage of the element MD at the point of time when discharge current through the resistance R2 and charge current through the resistance R7 are balanced, whereby the excessive discharge of the potential memorizing element beyond -100mV is prevented.

IPC: G03B15/05
Filed: 1994-06-22
Abstract: PURPOSE:To enable a charging circuit to be protected without the use of an ambient temperature detection means by detecting a charging voltage after a period of time set by a timer means, and stopping boosting action according to the detected result and the detected source voltage, and issuing an alarm. CONSTITUTION:Light energy is supplied to a flash discharge tube 14 from a main capacitor 6 which is charged by a booster means 3. A timer means that is started after the start of charging action to measure a set time is built into a one-chip microcomputer 17. After the period of time set by the timer means has elapsed, the voltage of the capacitor 6 is detected by a charging voltage detection means 5. Also, source voltage is detected by a source battery voltage detection means built into the microcomputer 17, and when the source voltage is at a set level or higher and the charging voltage is at the set level or lower, for example, the boosting action is stopped and an alarm is issued. Therefore, a charging circuit can be protected without the use of an ambient temperature detection means with a large circuit scale.

Title: Device for admitting dust-laden gases for a bag filter
Inventor: SHINOZAKI TAKESHI
IPC: B01D46/42
Filed: 1987-07-02
Abstract: PURPOSE:To prevent wear of a bag filter caused by impingement of high-speed dust-laden gases on the bag filter, by providing multistage impingement plates and a perforated distribution plate at a dust-laden-gas flow inlet of the bag filter. CONSTITUTION:Multistage impingement plates 8 are arranged nearly vertically and parallelly to each other below an inlet hood 2 of a bag filter. Dust traps 9 are formed at each upper end of the impingement plates 8 and louver plates 10 are provided at each lower end thereof. Consequently, a part of dust-laden gases flowing in from a gas inlet 4 goes upwardly along the impingement plates 8 to be checked by the dust traps 9 so that the inertia of gas flow is weakened, resulting in falling down of coarse particles due to impingement thereof upon the traps. As a result, average flow velocity at the bag filters 7 decreases, resulting in less wear thereof.

Title: Power source circuit of portable magnetic sound recording and reproducing device
Inventor: SAKA YASUHIKO
IPC: G11B33/00
Filed: 1981-10-16
Abstract: PURPOSE:To prevent batteries from being consumed when left turned on by mistake by turning on and off a transistor (TR) switch every time a nonlock type power source and play switch is pressed, and turning on and off the power source through one switch. CONSTITUTION:When a power and play switch 10 is pressed, the capacitor of a control power source holding circuit 13 is charged and a JKFF12 is initialized. Then, a terminal CK is held at a high level through a chattering preventing circuit 11. While a terminal CLR is at a low level, a terminal Q' of the FF12 is held at the high level without reference to the states of other terminals and a TRTR2 and then a TRTR1 turn on successively to supply currents to a motor 14 and an amplifier 15. When the switch 10 is pressed, the terminal CK of the FF12 is held at the high level and the terminal Q' is held at the low level to turn off both the TRs Tr2 and Tr1. When recording and reproducing end and an auto stop switch 16 turns on, the FF12 operates similarly. Consequently, one switch performs sufficient operation and while the constitution is reduced, the unnecessary consumption of batteries is prevented when the switch is left turned on by mistake.
