Title: Agitating and mixing effect detector
Inventor: IIJIMA AKIRA
IPC: B01F15/00
Filed: 1979-09-29
Abstract: PURPOSE:To compare position deviations of a prime moving shaft and a driven shaft attached with agitating vanes owing to viscosity changes and detecting mixing effect accurately by connecting both shafts by means of a spring. CONSTITUTION:Discs 6 and 7 are mounted to shafts 1, 2 in such a manner that the grooves 6', 7' of said discs assume the same position. Next, when this agitating part is put in the treating material and is revolved, the shafts 1, 2 cause position deviations by way of a spring 2 owing to the resistance of the treating material. At this time, the pulse output Q6 by the groove 6' of a photointerruptor 9 operates a flip- flop 12 via an amplifier 11, thereby opening a gate 13. Then, a series of the pulse outputs Q1 of the photointerruptor 8 of the disc 5 are measured with a counter 14 by way of the gate 13. When the groove 7' comes to the position of a phtointerruptor 10 with theta delay, a pulse Q7 is outputted to close the gate 13. In this way, the pulses are counted by the number corresponding to the angle theta with a counter 14 and the count number is displayed in a display device 17. Hence, if the degree of agitating and mixing progresses and the viscosity changes, the deviation of the driven shaft 2 also changes and the numerical value corresponding to the viscosity is displayed in a display device 17.

Title: Mixer
Inventor: ITO KENJI
IPC: H03D9/06
Filed: 1990-05-16
Abstract: PURPOSE:To operate the mixer over a side frequency range by inputting a signal to a diode ring circuit through a balanced line and an unbalanced line, inputting a local oscillation signal to one of said balanced line and unbalanced line, and inputting a high frequency signal or a center frequency signal to the other. CONSTITUTION:A local oscillation signal inputted from a local oscillation signal terminal 2 is fed from terminals 13, 14 of a balanced line 16 of a diode ring circuit 11 to the circuit 11. Moreover, a high frequency signal is inputted to a high frequency signal terminal 1 of a branching filter 19 having the high frequency signal terminal 1 and fed to the diode ring circuit 11 via an unbalanced line 15 having a terminal 12. Since the mode of applying an electric field to the diode ring circuit 11 differs from the balanced line 16 and the unbalanced line 15, the local oscillation signal and the other signal are separated. Thus, since the frequency characteristic requested to the filter is considerably relaxed, the operation over a broad frequency range is attained.

Title: Echo canceller
Inventor: SUZUKI SHIGEAKI
IPC: H04B3/23
Filed: 1989-05-19
Abstract: PURPOSE:To prevent an echo path estimating error from being increased due to a delay in the detection of 2-way simultaneous talking state by correcting a register storing an impulse response estimate value of an echo path through the use of a preceding signal by (M-1)-sample. CONSTITUTION:Impulse response estimate values ho(j), h1(j),...,-hN-1(j)stored in a 2nd register are corrected by using a signal e(j-M-1) of the oldest sample among signals stored in a 3rd register and reception signals X(j-M+1), X(j-M),..., X(j-N-M+2) among those stored in the 1st register. When the correction is implemented by using the signal older by (M-1) sample and the value M is set properly, after the 2-way simultaneous talking state is started, the 2nd register correction till the state is detected uses the signal before the 2-way simultaneous talking state is started. Thus, the increase in the echo path estimating error is prevented.

Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To increase the discharge capacity in the high-rate discharge of a lead-acid battery by making an acid resisting metal oxide and sulfuric acid ions present in a negative electrode active material in the state where they are electrostatically bonded to each other. SOLUTION: As the acid resisting metal oxide, silica, alumina or the like is included, and it is present in a negative electrode active material in the state where it is in contact with an aqueous solution of sulfuric acid showing a pH lower than its equal acid point. In a lead-acid battery, an electrolyte (aqueous solution of sulfuric acid) has a high concentration and a low pH. The charged quantity of a material electrostatically bonded thereto is extremely large in this state. When the lead-acid battery is discharged, and the discharge is progressed, the pH of the electrolyte is gradually increased, while the charged quantity of the electrostatically bonded material is decreased. At this time, sulfuric ions are released from the electrostatically bonded material.  Thus, the sulfuric ions which are discharge reaction-participating materials can be newly supplied even in a high-rate discharge, and the high-rate discharge characteristic can be improved.
