Title: Circuit for detecting in-band sf signal by digital signal processing
Inventor: MORIMURA HIROSHI
IPC: H04L27/26
Filed: 1983-03-28
Abstract: PURPOSE:To improve the miniaturization and economy by utilizing effectively a digital signal processing function by means of time division and using an integration circuit having a very different time constant in detecting signal power. CONSTITUTION:When digitized sound signal of plural channels is given to an input terminal 1 in the form of time division, a selected SF signal and a frequency component other than the SF signal are extracted, they are converted respectively into an absolute value and signals (d), (e) are outputted. The signal (d) is applied to the integration circuit 6 so as not to delay the response and converted into a DC signal f1. The signal (e) is applied to another integration circuit 7 and the signal (e) is converted into a signal f2 having a DC waveform with remarkably slow response. The signals f1, f2 are applied respectively to a level comparison circuit 8, the level of the both is compared and a signal (g) is outputted to an output terminal 9 as an in-band SF signal. Even if the level of the input signal is changed, so long as the signal width DELTAt is constant, the pulse width DELTAt' of the signal (g) is made constant.

Title: Electronic watch
Inventor: SHIMAZAKI AKIO
IPC: G04C10/00
Filed: 1978-04-27
Abstract: PURPOSE:To prevent the stop of watch function owing to the drop of battery voltage by detecting the drop of batery voltage from boosting voltage and inhibiting an alarm function. CONSTITUTION:When the ON resistance of an N channel transistor 4 is let to be r1, the input of an inverter 5 becomes VDD(R2 + r1)/(R1 + R2 + r1) which has voltage-divided the output VDD of a boosting circuit 3 and therefore the resistance values R1, R2 of resistances 1, 2 are beforehand so set that the relation of VDT(R2 + r1)/(R1 + R2 + r1) < VTH holds with the threshold voltage VTH of the inverter 5. Then, when the voltage VDD becomes lower than VDT, the output of a NAND gate 8 becomes ''H'' and the buzzer switch input 6 inhibits the buzzer irrespective of ''H'' of ''L''. Hence, the power consumption by the buzzer operation at the battery voltage drop may be suppressed and the stop of the watch function is prevented.

Title: Saturation detector for video camera
IPC: H04N5/225
Filed: 1992-03-10
Abstract: PURPOSE:To raise warning by correctly executing saturation detection independently of a hue of an object. CONSTITUTION:Three primary color signals R, G, B from sample-and-hold circuits 4R, 4G, 4B are fed to a maximum value circuit 12, from which a signal of maximum level Smax is extracted. The signal Smax is compared with a saturation detection level Vsat at a comparator 13 and a comparison output SW is used to apply changeover control to a switch 10. When any of image pickup equipments 3R, 3G, 3B is saturated, the level of the signal Smax exceeds the saturation detection level Vsat and a comparison output SW goes to '1' and the switch 10 is thrown to the position (a). Thus, when any of the image pickup equipments 3R, 3G, 3B is saturated, a zebra pattern is displayed on an EVF11. Since the saturation is not detected by using a luminance signal being the synthesis of the three primary color signals, the saturation is detected surely independently of a hue of the object to raise warning.

Title: Transformer for loudness control
Inventor: FUJITA SADAO
IPC: H03G9/00
Filed: 1989-03-06
Abstract: PURPOSE:To allow the user to correct the sound volume to its own preferred sound volume and to simplify the circuit by varying a sound volume adjustment device with a loudness control circuit and varying the intensity of a low sound frequency and a high sound frequency through the use of a transformer or a choke coil automatically. CONSTITUTION:When a sound volume is changed by a variable resistor and the sound volume is at a maximum, the amplification factor for low, medium and high sound frequency signals is made constant. Moreover, as the sound volume decreases, the amplification factor of the middle sound frequency gets higher than that of the low and high sound frequencies and the rate gets higher as the sound volume is lowered. Thus, the fact of the change in the reactance of a transformer or a choke coil due to a frequency change is utilized. For example, the sound volume adjustment device 1 is set to -30dB as the adjustment method at the setting. In this case, an ANP 4 is set to a maximum or proper gain position and the gain of a radio tuner 5 is adjusted to set the sound volume in 60dB by a reading of a sound pressure meter or in a dB of usual conversation by human ears. When the gain of each sound source is made coincident, the sound pressure with a maximum '1' is 90dB and the characteristic in the low, medium and high sound frequencies in the sound pressure of a speaker is made flat. Then the sound pressure characteristic of low, medium and high sound frequencies is varied with a change of 1 and the ideal operation is attained.

IPC: H05B41/14
Filed: 1979-04-26
Abstract: PURPOSE:To prevent continuous electric discharge after flash discharge, by providing a charge control circuit and operating an electric power source switch. CONSTITUTION:When a charge start operation switch 16 is closed, a power switch 6 is closed when the charged voltage is low to charge, and when the charged voltage in a discharge capacitor 8 reaches a specified value, the output voltage of a capacitor voltage detecting circuit 9 becomes larger than the output voltage of a charge completion reference voltage generating circuit 13. As a result, a charge completion voltage comparator 12 operates to open the switch 6 through an AND gate 15. A trigger pulse is applied from a trigger pulse generating circuit 11 to a flash discharge tube 10, and the electric charge in the capacitor 8 is applied to the discharge tube 10 discharge a flash. As a result of this discharge, when the voltage in the capacitor 8 declines below a specified value, a charge break timer circuit 14 issues a signal to open the switch 6 for specified time through the gate 15. When the charge break signal stops after elapse of specified time, the switch 6 is closed to start charging into the capacitor 8. By this charge pause for specified time, the residual ions in the discharge tube 10 are extinguished, so that continuous discharge may be prevented.
