Title: Inspector for spot welding
Inventor: TANIZAKI TOSHIO
IPC: B23K11/25
Filed: 1977-10-17
Abstract: PURPOSE: To make possible the exact inspection on the quality of the weld zone, by operating double integration for the signal being sent from the acceleration sensor attached to the electrode tip holder, and by converting this signal to a signal corresponding to the displacement of the electrode tip and the electrode holder.  
     CONSTITUTION: The signal from the acceleration sensor 6 is amplified by the amplifier 8 and is inputted to the double integration circuit 10 and the trigger circuit 11 through the gain adjusting variable resistor 9. The trigger circuit 11 starts the gate timers 12W13 depending on the leading of the acceleration signal; while the gate timer 13 is starting, the gate circuit 14 sends the displacement signal from the double integration circuit 10 to the maximum amplitude arithmetic circuit 15. This signal is sent to the judging circuit 16 which produces the scattering generation signal when the input signal is larger than the upper limit, or produces the defective weld signal when the input signal is smaller than settled lower limit, or produces the good weld product signal in other cases. According to this method, the exact inspection on the judgment for the quality is carried out in the spot welding

Title: Field discrimination circuit
Inventor: BABA HIROYUKI
IPC: H04N5/10
Filed: 1987-05-21
Abstract: PURPOSE:To reduce a load in circuit design by discriminating the signal level of a horizontal synchronizing signal which is synchronized with the phase of the horizontal synchronizing signal among composite synchronizing signals with the timing of a vertical synchronizing signal. CONSTITUTION:The horizontal synchronizing signal 103 outputted from a horizontal synchronizing PLL (Phase Locked Loop) circuit 100 is synchronized with the phase of the horizontal synchronizing signal 103. Since the number of equalization pulses which exist in front and behind the vertical synchronizing signal 104 differs in odd-numbered fields and even-numbered fields, the phase of the horizontal synchronizing signal 103 with respect to the vertical synchronizing signal 104 differs by a half period in the odd-numbered fields and in the even- numbered fields. Namely, when the signal level of the horizontal synchronizing signal 103 is discriminated at the timing of the vertical synchronizing signal 104, the signal level is inverted by the odd-numbered fields and the even- numbered fields, whereby field discrimination can be executed. Thus, the load of circuit design can be reduced.

Abstract: PURPOSE:To calculate the wavelength of an incident light accurately, by primarily specifying the wavelength of visible light incident into a wavelength discrimination element from the ratio of the photocurrent when a reverse bias is applied to the wavelength discrimination element to that when no bias is applied. CONSTITUTION:A bias switch 2 applies a bias value of 2 levels such as 0V and 1V alternately to a wavelength discrimination element 1 periodically by a reverse bias according to a bias change signal from a signal processor 4. In response to this, the photocurrent flowing from an element 1 takes two values J(0) and J(-1) alternately and hence, the signal processor 4 reads the output of an amplifier 3 synchronizing a bias switching signal to detect the photocurrent values J(0) and J(-1). Subsequently, the signal processor 4 determines a standardized collection efficiency J(0)/J(-1) by a computation, a table of the dependency of the standardized collection efficiency J(0)/J(-1) on the wavelength previously memorized into the signal processor 4 is used to obtain the value of conversion of light incident into the wavelength discrimination element 1 to a monochroic light and the results are outputted to a terminal 5.

Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To quickly achieve the practical level without requiring a large quantity of training data on a new speaker by generating adaptation model by use of voice input from a new speaker to train an adaptation model while using a set of main component vectors. SOLUTION: A training speaker 20 of a T person gives document for training data so that a native space is constructed, and the training data is used for training a speaker dependence(SD) model 24. After a super vector is constructed for each training speaker, main component analysis is executed (32). The main component analysis on T-number of super vectors gives T-number of characteristic vectos (34). N-number of vectors are extracted arbitrarily from the T-number of characteristic vectors (36) to construct a native space for parameters decreased in number of dimensions (38). When the native space is once constructed, speaker adaptation or environment adaptation can be easily achieved. In this case, adaptation is comparatively simple computing operation, and it can be executed even during the use of the system by a new speaker.
