Title: Digital low-pass filter
Inventor: HASHIMOTO HIROYUKI
IPC: H03H17/06
Filed: 1987-07-06
Abstract: PURPOSE:To correct a group delay distortion of a middle and high component of a speaker giving adverse effect onto sound quality by setting s coefficient having the group delay distortion characteristic having a delay time increased smoothly as the frequency becomes higher in a pass band. CONSTITUTION:In a figure representing the frequency characteristic of a digital low-pass filter, G1(omega) shows the amplitude frequency characteristic and tau1(omega) depicts the group delay distortion characteristic. In mounting the digital low-pass filter onto a CD player, although the basic building block is the same as that of a conventional example, the coefficient of the digital low-pass filter being one of the components is selected to provide the group delay characteristic in a range where the delay time deviation is within 0.0-3.0msec in the pass band shown in figure. Thus, the group delay distortion is corrected and the sound quality of the reproduced sound is improved.

The amount of displacement of the probes 4 is detected by a differential transformer 5, and the value of the outer diameter SD at the seaming band part is measured. The value of the thickness T of the double seaming part of the can body and the value of the outer diameter SD at the seaming band part have relationship shown by a straight line having the gradient in the range of 1.6-2.0, even though the value is slightly changed depending on the thickness and the raw  material of the plate constituting the can body and winding tools. Therefore,  the value of the T which is the thickness of the double seamed part can be simply measured from this relationship, and the continuous measurement can be performed.

Abstract: PURPOSE:To perform the accurate inspection of the pressure in a can all the time regardless of the detected oscillatory wave pattern. CONSTITUTION:An apparatus for inspecting the pressure in a can has the parts performing the following functions. An exciting means 16 forcibly excites free oscillation in an elastic wall surface 12a of a can 12.

A Fourier transformation means 22 performs Fourier transformation of the oscillatory wave, which is detected with the oscillator-wave detecting means 16, and separates the oscillatory wave into a plurality of the oscillatory-wave components. A frequency selecting means 24 selects the oscillator-wave component, which is present in a frequency band having the correlation with the pressure in the can, out of the oscillatory-wave components, which are separated with the Fourier transformation means 22. A judging means 28 judges whether the frequency of the oscillatory wave, which is selected with the frequency selecting means 24, is located in the intended region or not and outputs the defective internal pressure signal when the frequency is located at the outside of the intended region.

Title: Decoding circuit
Inventor: NAKAIZUMI KAZUO
IPC: G11C11/413
Filed: 1981-10-21
Abstract: PURPOSE:To operate the whole decoding circuit at a high speed, and also to reduce an occupied area on a mask, by reducing the load capacity of an OR circuit, and also decreasing the number of inverting circuit elements. CONSTITUTION:Operation of OR is same as that of a conventional circuit. When a decoder is selected, an output YjR1 becomes ''1'' level. On the other hand, at the time of read, an output YjW1 becomes ''0'' since a control signal WEY is ''1''. Also, at the time of write, WEY is ''0'' and YjR1 is ''1'', therefore, YjW1 is charged to ''1'' through each drain-source of a transistor (Tr)P10 and P11. Subsequently, in case when the decoder is not selected, NO10 becomes ''1'', YjR1 becomes ''0'', and the output YjW1 becomes ''1'' at the time of read and at the time of write. In this case, as for operation of Tr, N12, when a level of YjW1 drops to ¦VTP¦, the transistor P11 is turned off, it is prevented to become high impedance in a level below ¦VTP¦, and accordingly Tr, N12, small size is enough.

Title: Storing form control system
Inventor: OKANO NAOKI
IPC: G06F5/06
Filed: 1988-07-07
Abstract: PURPOSE:To attain the effective application of the capacity of a buffer by storing a flag showing the continuous transfer of the same data into the buffer in addition of data to show these data if said flag is not set and to show the continuous transfer frequency of the same data if the flag is set respectively. CONSTITUTION:A comparison means 12 compares the data with the data inputted immediately before the first data and a counter 14 counts the frequencies where the coincidence is secured among the results of comparison obtained by the means 12. A writing means 15 writes the count value of the counter 14 and a flag showing this count value into a memory means 20 instead of data when the coincidence is changed to the discordance obtained among the results of comparison of the means 12. Then said flag is detected by a flag detecting means 30 when the data are read out, and a data transmission means 33 transmits continuously the data right before detection of the flag by the frequency shown by the count value when it is shown that the flag is equal to the count value. In such a way, the continuous transfer frequency of the same data is stored. Thus the storage capacity of a buffer 20 is effectively used.

Title: Dc regenerating circuit
Inventor: YOSHIDA SEIICHIROU
IPC: H04N5/16
Filed: 1982-09-28
Abstract: PURPOSE:To reduce the DC fluctuation, by replacing a DC level of a period into the DC level before one period, when a reference level signal superimposed periodically is fluctuated in excess of a specified value. CONSTITUTION:If a noise is superimposed on the reference level signal having a period T2, it is detected at a detecting circuit, an output 61 of an exclusive OR 48 goes to H, and an output of an AND gate 39 goes to L. Thus, an analog switch 58 turned on with the H level of an output 27 is turned off once to inhibit the charging of a capacitor 52. Further, since a pulse is outputted to an output 25 of a gate 40 at the same time when an output 24 of a gate 39 goes to L, a pulse is inputted to a set input 30 of a toggle FF 45 and its Q output 26 goes to H and a Q output 27 goes to L. Then, since this state is kept for the period T2, a switch 59 is turned on again and the DC regeneration is attained with a capacitor 51 charged to a suitable level without being affected with the reference level fluctuation.
