Title: Digital television receiver
Inventor: KUDO YUKINORI
IPC: H04N5/44
Filed: 1990-11-29
Abstract: PURPOSE:To stable keep the standard mode even when a horizontal synchronizing signal is disturbed by external disturbance by detecting the mode not to be the standard mode with an integration circuit for plural number of times when a standard mode detection signal is switched from a 1st state (standard mode) into a 2nd state (nonstandard mode). CONSTITUTION:A horizontal synchronizing signal is detected from a digital video signal, the period of the horizontal synchronizing detection signal is stored and whether or not an incoming video signal is in the standard mode is detected repetitively in a prescribed timing based on the output of a horizontal period memory circuit. When the result of detection of the horizontal standard mode tells the standard mode, the horizontal standard mode detection signal is brought into the 1st state and when the nonstandard mode is detected, an output of a horizontal standard mode detection gate circuit is integrated and when the result of integration tells it that the mode is not the standard mode for a prescribed number of times consecutively, the horizontal standard mode detection signal is brought into the 2nd state. Thus, the standard mode signal such as a broadcast signal and the signal of the nonstandard mode such as a signal obtained from a video game device or the like are distinguished stably.

IPC: H03K17/74
Filed: 1987-12-23
Abstract: PURPOSE:To prevent an output offset voltage due to a difference from the temperature rise by detecting a side current sensing resistor to a bridge circuit and controlling the upper or lower current of the bridge to be constant. CONSTITUTION:When a base voltage VQ6 of a TrQ6 is higher than a base voltage VQ5 of a transistor(TR) Q5 in a bridge stabilizing control circuit 7, a current I6 from the TrQ5 increases and a negative output current I2 outputted from a load current supply circuit 60 to a bridge circuit 10 is decreased. Thus, the relation of VQ5=VQ6 exists in a feedback system consisting of Trs Q5, Q6 being the components of the differential amplifier in the circuit 7 and of a Tr Q2 of the circuit 60. Thus, the relation of IB1=IB2 exists in the circuit 10 and a voltage Valpha1 at the input terminal and a voltage Vbeta1, at the output terminal of the circuit 10 are made equal by employing diodes D1, D2 having the same voltage/current characteristic under the same condition. A positive current supply circuit 50 and the circuit 60 are subject to ON/OFF control by an off- control circuit 4, resulting that diodes D1-D4 of the circuit 10 are subject to turn-on, turn-off control.

Title: Image recorder
Inventor: SUZUKI AKIO
IPC: B41J2/12
Filed: 1990-11-29
Abstract: PURPOSE:To prevent changes in recording density of a recording head due to changes in temperature by providing a controller which corrects input image signals corresponding to the difference between the recording head temperatures during stoppage of recording and at re-start of recording when recording action is re-started. CONSTITUTION:When receiving a signal, a CPU 111 detects the temperature T1 of an ink-jet recording head 112 according to a head temperature signal 123 output from a head temperature detector 113, and stores it in a built-in memory. Then the CPU 111 wait until a host computer 101 finishes transferring the succeeding image data to an interface 103. After that, immediately before the next printing is started after data transfer is completed, the CPU 111 detects the temperature T2 of the ink-jet recording head 112 again and calculates a difference T1--T2. When T1 becomes higher and higher than T2, a table containing larger factors is selected at re-start-up. Because, the image signal is compensated by increasing the image data level even when recording density is reduced due to a fall in the temperature during standby period.

Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To provide an adaptive equalizer which can secure the excellent equalization characteristic despite the timing offset given to a sampling clock. SOLUTION: The received input signal undergoes a convolutional operation with a tap coefficient via a filter 61 of the preceding stage, so that the sampling timing is controlled. A viterbi algorithm circuit 37 outputs a decision signal via the maximum likelihood series estimation and also outputs a complex symbol series candidate with an error signal, i.e., the difference between the output of the filter 61 and the replica signal of a replica signal generation means 62 used as the likelihood information. A filter 62 convolutes the transmission line characteristic estimation value to the complex symbol series candidate to produce a replica signal.  A parameter estimation circuit 47 estimates the tap coefficient and the transmission line characteristic estimation value so as to minimize the average square of the error signal under the constraint condition that fixes a specific element of the transmission line characteristic estimation value based on the input signal and the decision signal.

IPC: H01L21/68
Filed: 1990-11-27
Abstract: PURPOSE:To more quickly perform an orientation-flat alignment operation by a method wherein a sensor itself is moved to a direction which is reverse to the direction of rotation of a wafer, the positional relationship between the wafer and the sensor is changed, the position of an orientation flat is recognized and the orientation-flat alignment operation is performed. CONSTITUTION:A wafer shaft 2 is situated in the center of a wafer 1 ; a sensor 3 is situated in a position which is at the distance of a wafer radius from the center of the wafer shaft 2. When the wafer 1 is turned in the counterclockwise direction by an arrow 5 and the sensor is moved along a locus to a direction which is reverse to that of the wafer 1, a state that the sensor appears and disappears is quickened. That is to say, when the speed of revolution of the wafer is not increased but the movement speed of the sensor 3 is increased, the position of an orientation flat can be recognized more quickly. Thereby, it is possible to align the orientation flat more quickly.
