Title: Automatic luminance limiting circuit
Inventor: SHIMONO YOSHIO
IPC: H04N5/59
Filed: 1991-06-21
Abstract: PURPOSE:To improve the quality of an image by setting the detection voltage of an anode current detection terminal and providing an operation amplifier executing the feedback of resistance value zero from an output terminal to an input terminal and an emitter-follower circuit at a stage behind it. CONSTITUTION:The voltage and the luminance control voltage of the anode current detection circuit 10 are respectively set to be V1 and V2 and the base voltage of the emitter-follower circuit TR1 to be V3. The cathode applied voltage of a diode X12 for automatic luminance limiting ABL and that of a resistance R1 are supplied in common and set to be E1. As the output terminal and the minus input terminal of the operation amplifier 13 feedback with a resistance value zero, an amplification degree becomes 1 and output voltage becomes the same value as the voltage of a plus input terminal. At the time of ABL off, the value of V3 becomes V3 E1 as X12 is off, so that the value is not affected by the amplifier 13, R1 and R2. At the time of setting a control sensitivity, even if the values of R1 and R2 is changed, the center of luminance does not vary as V3 is a fixed value.

Inventor: SASAKI RYOICHI
IPC: B41J5/30
Filed: 1988-07-15
Abstract: PURPOSE:To promptly input character data by shifting the character data at an array end to the next array when the input array exceeds a prescribed range by the input of the character data expressing the character and a symbol. CONSTITUTION:When a display means M3 reads the character data from an input data memory means M2 to display them on a display screen, and a judging means M5 judges that the undisplayed character data remain in the data memory means M2, an automatic line-feed prohibiting means M5 prohibits the automatic line-feed operation of an automatic line-feed means M4. As a result, when the character data are promptly inputted through an input means M1, and the character data are accumulated in the data memory means M2, the display time of the character data is shortened for the time necessary for the operation of the automatic line-feed means M5. Thus, the large quantities of the character data can be promptly inputted.

Title: Sound signal processor and method thereof
Inventor: UIRIAMU ARUBAATO FUOODO
IPC: H04B3/23
Filed: 1990-07-06
Abstract: PURPOSE: To reduce the cost of an adaptive filter by improving the reliability of the filter by eliminating the reproducing tendency by using an adaptive echo canceling method in a reception channel and cancelling the speaker phone talker echo through a hybrid. CONSTITUTION: An echo canceller 225 generates the replica of a sound impulse response at a hybrid coupling path by using the sample of the voice signal in a transmission channel. The hybrid coupling path only gives far-end voices as the output of the canceller by subtracting the far end voices from the combination of local echoes given from a hybrid 10 and far end voices. Thus the transmitting signal given to the transmission channel is cancelled through the hybrid coupling path. Therefore, the cost of an adaptive filter used as the acoustic echo canceller 225 is reduced because the reliability of the filter is improved.

Title: Igniting device of internal-combustion engine
Inventor: YOSHIOKA TORU
IPC: F02P3/08
Filed: 1984-08-27
Abstract: PURPOSE:To effect lead of an angle according to the number of revolutions, by selecting the time constants of a third capacitor and a third discharging circuit so that they are completely discharged during low speed rotation when a second voltage is generated and they are prevented from complete discharge during high speed rotation. CONSTITUTION:During low speed rotation, a negative exciter voltage VN1 is increased over that of a capacitor C1 between (e) and (f) of an exciter coil L4, a diode D14 and transistor Tr4 are turned ON and for discharge, and when it exceeds a peak value, disharge is effected through resistance. The Tr4 is turned OFF to turn ON an SCR to ignite an ignition plug P. At a time when VN1 is generated during high speed rotation, the capacitor C1 is not discharged completely, thereby a capacitor C0, charged by a positive exciter voltage, is discharged during generation of a first negative exciter voltage at a next period to ignite the ignition plug P. Thus, ignition is effected in a further lead angle with the increase in the number of revolutions without exercising an influence on an ignition timing by charging of the C0.

Abstract: PURPOSE:To detect the tape winding diameter only with tape loading operation by dividing the differences between the tape length in the unloading state and that in the loading state by the angle of rotation of a reel shaft for winding to detect the tape winding diameter. CONSTITUTION:In the unloading state, a reel shaft A is braked by a brake mechanism 10 to fix a supply reel 1. At this time, the length of a tape 5 is l1. When the loading state is set next, the tape 5 is fed out from a take-up reel 2 and its length is changed, but the difference between them is always fixed. The take-up reel 2 is driven in response to the loading end detection signal of a loading end detecting part 11, and the tape is wound up by the difference. At the time of this taking-up, pulses whose number is proportional to the angle of rotation are outputted from a rotation angle detecting circuit 6. Thus, a radius calculating circuit 7 calculates the radius of the tape wound around the take-up reel 2 to immediately confirm the residual quantity of the tape.
