Title: Ultrasonic pulse compression apparatus
Inventor: MATSUI KOICHI
IPC: G01N29/44
Filed: 1989-04-28
Abstract: PURPOSE:To expand a dynamic range and to always accurately compress a receiving signal by respectively providing variable gain amplifiers to the front and rear stages of a correlation circuit and controlling respective gains on the basis of the receiving signal so that the whole gain becomes always constant. CONSTITUTION:The first variable gain amplifier 2 amplifies the receiving signal of the ultrasonic waves changing in frequency with the elapse of time obtained from an ultrasonic vibrator 1 and a correlation circuit 7 takes the correlation of the output of the variable gain amplifier 2 with a reference wave to subject the receiving signal to pulse compression. The second variable gain amplifier 15 amplifies the output of the correlation circuit 7 and a gain controller 17 extracts a higher harmonic component through a high-pass filter 16 because the output of the variable gain amplifier 2 is distorted when the level of the receiving signal from the ultrasonic vibrator 1 is high and the higher harmonic component is outputted much with respect to the receiving signal and reduces the gain of the variable gain amplifier 2 so that the total gain due to the variable gain amplifiers 2, 15 becomes always constant and performs control so as to increase the gain of the variable gain amplifier 15.

Title: Plate thickness control method
Inventor: MIURA HIROAKI
IPC: B21B37/16
Filed: 1986-05-16
Abstract: PURPOSE:To improve the plate thickness accuracy by performing an independent and automatic thickness control at each stand, comparing each draft position deviation amount of adjacent stands, and eliminating a draft imbalance between the stands based on the above comparison. CONSTITUTION:Gage meter type automatic plate thickness controls at adjacent stands (i-1) and (i) are prepared, respectively. Then, draft position deviation amounts DELTASi and DELTASi-1 of the respective adjacent stands are compared in addition to the above independent control. In other words, a plate thickness deviation at the former stand is varied when a biaslike draft correction amount being additional to an automatic draft control amount is added to the deviation amount DELTASi-1. In that time, the deviation is varied so that a relative ratio between the deviation amounts DELTASi and DELTASi-1 reaches a constant value. In that way, the plate thickness accuracy and the plate flatness are remarkably improved because a draft imbalance between adjacent stands is eliminated.

Filed: 1993-05-14
Abstract: PURPOSE:To obtain a line drawing data retrieving method which can reduce the amount of sent data through easy processing by deciding a feature point on each continuous line included in a drawing to be outputted is inside or outside a set area. CONSTITUTION:Feature points inside the set area 2 are selected first and feature points which adjacent to the feature points inside the set area 2 among feature points outside the set area 2 are selected secondarily. For example, feature points P2-P4, P9-P11, and P14 and P15 are inside the set area 2, so they are selected. Feature points P1, P5, P12, P13, and P15 are adjacent to the feature points inside the set area 2, so they are selected. Remaining feature points P6, P7, P17, and P18, on the other hand, are neither inside the set area 2 nor adjacent to the feature points inside the set area 2, so they are excluded. Consequently, when data are sent to a terminal, a jump from the feature point P5 to the feature point P8 is made. The intersections of the frame lines which define the set area and the lines need not be found and the calculation quantity for sent data determination may be small.

IPC: G06F1/10
Filed: 1984-06-04
Abstract: PURPOSE:To omit the resetting of the delay time and to attain application even to a slot-free type system by providing a delay circuit in consideration of the delay time on a mother board and supplying the clock signals of different phases. CONSTITUTION:A mother board 20 is drivded into three groups, and T1 shows the delay time of transmission on the board 20 for PB1-5. While T2 shows the delay time of transmission for PB5-9 respectively. The delay times of delay circuits 3 and 4 are set at T2 and T1+T2 respectively. The signal delivered from an oscillation circuit 1 is divided by a dividing circuit 2, and a delay T2 is produced at the circuit 3 together with a delay T1+T2 produced at the circuit 4. Therefore the output of the circuit 4 is transmitted as it is to the PB1; while the output of the circuit 2 is delivered as it is to the PB9. Thus T1+T2 is added to the PB9, and waveforms of PB1, 5 and 9 have the same phase. This omit the resetting of the delay time, and the synchronizing clock signals are obtained in each group on the board 20. This method can be applied even to a slot-free type system.
