Patent JP-H07210178-A (JP)
Title: Active noise controller
Inventor: NAKAMURA MITSURU
IPC: H03H21/00
Filed: 1994-01-19
Abstract: PURPOSE:To efficiently actively muffle a random noise provided with a spectrum structure where the noise is distributed over wider bands, and whose low frequency band excels. CONSTITUTION:A reference signal after passing through a low-pass filter 41 is divided into two systems, and one side is made a low frequency signal control system, and the other side is made a high frequency signal control system, and they are in parallel controlled. A signal is inputted to the high frequency signal control system through high-pass filters 410, 411. A convergence coefficient is set so that the low frequency signal control system becomes faster initially in the adaptation of respective control systems. Thus, a low frequency noise and a high frequency noise are controlled in balance efficiently compared with the case when a wide band noise is processed collectively by the single adaptive filter.

Inventor: KATADA HIROYUKI
IPC: H04N19/60
Filed: 1991-01-17
Abstract: PURPOSE:To simply control a bit number by representing a total bit number with a limit as a function of A and varying the value A. CONSTITUTION:Let a total bit number in orthogonal transformation coding be B and a b(i) is quantified uniformly as a function of A expressed in equation I. Thus, a calculation section 1 calculates A(i, j), a calculation section 2 obtains a point S(n) at which the b(i) is incremented by one, and a decision section 3 decides the value A satisfying a relation of SIGMAb(i)=B. When the A cannot be decided, after a revision section 4 revises a value of (ln sigma(i)<2>)/a, a calculation section 5 calculates the b(i), and when the A is decided, the calculation section 5 calculates the b(i) without any calculation. The bit assignment b(i) in each transformation coefficient in the orthogonal transformation is implemented depending on the value sigma(i)<2> and to be an integer within a range.

Title: Electric brush
Inventor: NIHEI TORU
IPC: H01R39/18
Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To prevent missing when an electric brush is inserted and shorten the time required for replacement work by executing the chamfering of the particular width at the sliding surface to be in contact with a commutator and is parallel to the undercut groove formed on the commutator. SOLUTION: At the lower surface of this electric brush 1, namely at the sliding surface in contact with a commutator and parallel to the undercut groove formed on the commutator, chamfering 2 is executed in the length of 0.3 to 2.0 times the gap between the brush holder and commutator. In this case, if such length is less than 0.3 times the gap, insertion into the brush holder becomes difficult and the length exceeds 2.0 times, a degree of freedom of the inclination of the electric brush 1 in the brush holder becomes large, resulting in the fear for increase of vibration of the brush 1 during the sliding contact. Therefore, insertion of brush into the brush holder become easier and it is now possible to prevent missing during the insertion of brush and to shorten the time required for exchange work.

Title: Image forming device and control method therefor
Inventor: TANAKA MITSUGI
IPC: G03G15/08
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To decide residual toner by a simple constitution. SOLUTION: A D/A setting part sets the luminance level of a light source 102 which emits light corresponding to the density of an image to be formed and the light source 102 emits light at the set luminance. The light is reflected by the formed image, detected by a detecting part 103 and inputted in a comparison part 112. The comparison part 112 compares the value inputted from the A/D intake part with the value set by the D/A setting part, and when the difference between both becomes equal to or above a specified value, a fluorescent light of an operation panel 113 is turned on, on judgement that the residual toner becomes little. Moreover, a signal detected by the detecting part 103 is inputted to a developing bias decision part 109, the developing time bias is controlled thereby, and thus the density of the formed image is controlled.  Since the residual toner is judged in this way, an additional circuit therefor becomes unnecessary.
