Title: Quantization error diffusion circuit
Inventor: SHINDO YOSHIKUNI
IPC: H04N5/14
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a circuit for diffusing a quantization error without causing any interference or noise due to the influence of an error diffusion signal at the time of video display by using a signal synchronized with an input video signal as the error diffusion signal. SOLUTION: By inputting a horizontal synchronizing signal H and a vertical synchronizing signal V, an error diffusion signal generation circuit 1 outputs an error diffusion signal F1 to be inverted for every horizontal synchronization and every vertical synchronization and its inverted signal F2. Input signals, on which the error diffusion signals F1 and F2 are superimposed, are modulated like signals S1 and S2. The signal S1 is A/D converted by an A/D converter 4 and the quantization error is caused but the occurrence of the error is distributed for every horizontal synchronization and every vertical synchronization. It is similar for the signal S2 and the error distribution at an A/D converter 5 as well but since the signal F2 is inverted with respect to the signal F1, the direction of distribution is opposite to that of the signal S1 and the distribution at the A/D converter 4.  A multiplexer 7 performs a switching operation corresponding to a clock CK1 synchronized with the horizontal synchronizing signal H.

Title: Dust removing device for filter
Inventor: MURATA KATSUTAKA
IPC: A47L9/10
Filed: 1981-03-02
Abstract: PURPOSE: To surely remove dust collected in ravine parts of a filter, by providing a pressing part to a dust removing piece and pressing partially a filter frame following the movement of the piece.  
     CONSTITUTION: When a dust removing piece 14 slides laterally, a projection, not shown in the fig., toches vibration plates 13 to flip them in turn and causes vibration to shake off dust stuck to the filtering surface of a filter 7 to which the vibration is transmitted. In this case, a pressing part 16 of the piece 14 moves following the sliding of the piece 14 while pressing partially a sliding surface 11 formed in one piece to the inner surface of a filter frame 9 corresponding to both end parts of the filter 7. By this action, a part of the sliding surface 11 pressed by the part 16 bulges causing a spreading of one side and a contracting of another side of spaces t of ravine parts and between pleats of the filter 7. As a result, the dusts collected in the spaces t of the ravine parts are shaken off easily and surely.

Title: Processing device
Inventor: KITAHIRO ISAMU
IPC: B28D5/02
Filed: 1985-02-20
Abstract: PURPOSE:To facilitate processing and cutting of a work greatly and lessen the probability of failure of a grinding wheel during service by sensing the revolving speed of the grinding wheel, and decreasing the table feeding speed in compliance with the drop of the revolving speed sensed. CONSTITUTION:A work 3 is processed by a grinding wheel 1. In case the revolving speed of this grinding wheel 1 has dropped, the revolving speed of the spindle is sensed. The revolving speed sensed is transmitted to a conversion circuit 8 to be converted into a control signal for table feed speed-that is, a sensed drop in the revolving speed is sent to the control system for table 2, which reduces the feed speed of the table 2. This will accordingly lessen the load on the grinding wheel 1, which should restore its machining capacity. Even though the revolving speed has lowered, decrease in the table feed speed will restitute the revolving speed. Thus the revolving speed can be held constant at all times to enable cutting with the max. torque, which should substantially eliminate failure of grinding wheel as well as facilitate processing and cutting.
