Title: Noise eliminating system
Inventor: ACHIHA MASAHIKO
IPC: H04N5/21
Filed: 1978-08-21
Abstract: PURPOSE: To ensure an effective noise elimination by detecting the shift amount when the TV picture is shifted, shifting the 1-frame preceding picture signal by the amount of the shift amount of the TV picture and using this difference of the shift amount to control the coefficient for noise reduction.  
     CONSTITUTION: The noise eliminating circuit consists of input terminal 8, coefficient control circuits 9 and 10, adder 11, output terminal 12, frame memory 13, shift amount compensating circuits 14 and 15 plus subtractor 16 each. In such constitution, the shift amount of the subject is calculated at the 1-frame cycle from the input/output signal of memory 13 and via circuit 14, and the shift amount of the subject is compensated through circuit 15. After this, the difference between the compensated signal and the input signal is calculated by circuit 16, and this difference signal is used to control the coefficient of the circuit which controls the mixture ratio between the TV signals. As a result, the coefficient can be set small like in the case of the still picture, and accordingly the noise can be reduced effectively although the picture has some movement.

Title: Driving method for linear pulse motor
Inventor: MAEDA YUTAKA
IPC: H02P7/00
Filed: 1988-04-26
Abstract: PURPOSE:To avoid the influence of hysteresis characteristic on the deflection of a mover, by inverting the mover after the mover is deflected in the forward direction by as many command pulses as required by an amplitude, and by adding as many incremental component pulses as required by the amplitude at the time of the inversion, to the command pulse. CONSTITUTION:First, N command pulses according to an amplitude is applied, and a mover is deflected in the forward direction. After that, (2N+alpha1) pulses are applied, and the mover is deflected in the reverse direction. Besides, (N+alpha2) pulses are applied, and the mover is deflected in the forward direction, and the mover is returned to the point of deflection zero. In this case, the quantities alpha1 and alpha2 of incremental component pulses are set in a quantity according to the amplitude, and the generation time  t is made sufficiently shorter than command pulse generation times(t), 2t. As a result, influence by hysteresis characteristic can be cancelled.

Title: Method for detecting phase of turning angle of back-up roll in rolling mill
Inventor: HAYAMA YASUNOBU
IPC: B21B37/66
Filed: 1980-07-25
Abstract: PURPOSE:To minimize the eccentric fluctuating extent of an upper and lower back- up rolls through controlling the rolls so that the difference of the turning angles of the rolls becomes zero, by detecting the undulating waveform due to the eccentricity of the rolls and by obtaining the turning angles of the rolls. CONSTITUTION:In the 4-stage rolling mill, working rolls 1, 2 are allowed to contact each other and are rotated through charging load, and the fluctuation of the load due to the eccentricity of the upper and lower back-up rolls 3, 4 are detected by a load cell 5, and the waveform of undulation is obtained. This waveform of undulation is determined by the turning angle of the upper and lower back-up rolls 3, 4, so the amplitude of the undulation detected by the load cell 5 is determined by the difference of the turning angles of the upper and lower back-up rolls 3, 4, that is to say, by the phase. When the phase is zero, the amplitude of the eccentricity of rolls becomes minimum, therefore the eccentric fluctuating extent of rolls is minimized by controlling the turning angle of the back-up rolls 3, 4 so as to keep the phase almost zero.

Abstract: PURPOSE:To allow a writing format and a preparation format to respond to perfect (1 to 1) by providing a device that changes cutting-out of written characters in a recognizing section in respondence to the form of written characters and changes the threshold values for recognizing characters. CONSTITUTION:A character frame converting section 7 judges whether the character form mode designated by key operation of a tablet section is double em/em/en mode, and sets character frames for cutting out written characters as below and notifies to the recognizing section 2. In the case of en mode, the character frame converting section 7 sets a character written in an area as a lateral half of normal character frame as one character, and in the case of em mode, makes a character written in a normal character frame one character. In the case of longitudinal X lateral double em mode, the recognizing section 2 is notified so as to process characters written on an area twice the em character frames longitudinally and laterally, that is, em character frames as one character. In cases of en mode and double em mode, the character frame converting section 7 sets a new threshold value and reports to the recognizing section 2. The recognizing process is made by the recognizing section 2, and repeated for each character.

Title: Cutting ring for saw chain
Inventor: HONJO MASATO
IPC: B27B33/14
Filed: 1990-04-19
Abstract: PURPOSE:To effectively prevent a pivotal action of a cutting link by deviating a pivot coupling position of a side link to the cutting link from the center between the back of the cutting link and the end of a cutting link edge toward the edge side. CONSTITUTION:When a chain sprocket 7 is rotatably driven by a rotary driver in a direction of an arrow A, a saw chain 3 is fed to cut a material M to be cut. In this case, when a preceding cutting edge 21R of a cutting link 15 is intruded into the material to be cut, the link 15 is rotated in a direction of an arrow C to be tended to be floated (pivotal action). However, since the back 23 of the link 15 is brought into plane contact with the bottom 9B of a guide groove 9 and a pivot coupler with a side link 17 is deviated to the edges 21R, 21L side, the rotation of the link 15 in the direction of the arrow C is suppressed.

Title: Door opening and shutting device for selective exposure and closure of video recording reservation function of videocassette recorder
Inventor: KIN KEIITSU
IPC: G11B15/10
Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To prevent the recording of videos other than the desired ones and erroneous erasure of desired videos by opening a door which encloses the operating surface of a video recording reserving functional button only when a door opening button is pressed by releasing the interlocking means of the door interlocked with the functional button. SOLUTION: When a door opening button 20 on a front panel 10 is pressed, a pressurizing bar 21 actuates a tact switch 11a and a VTR is set to a video recording reservable state. In addition, the pressurizing member 22 of the button 20 moves forward simultaneously with the bar 21. Therefore, a locking pin 40 is moved upward by the slope 22a of the member 22 and the upper slope 43 of the pin 40 and, at the same time, the lower end section of the pin 40 is released from the through hole 32 of a door 30. As a result, the door 30 rotates forward and a video recording reserving function button 12 is exposed. The button 20 and pin 40 return to their initial states due to springs S and S' when the pressing forces are removed.  Therefore, the recording of videos other than the desired ones and erasure, etc., of information due to erroneous operation can be prevented, because the button 12 is exposed only when the button 12 is used.

Inventor: HORIUCHI MASATO
IPC: B65H29/58
Filed: 1981-07-02
Abstract: PURPOSE:To make it possible that a conveyor carries usually plate-shaped articles keeping their aspects unchanged but returns selectively some of them freely if necessary by contriving to convey the articles in the aspect as received and some of them in the reverse direction as required. CONSTITUTION:A plate-shaped article A is received at an entrance 2 and conveyed toward the left side in such a manner that it is as if engaged with a belt 35 and a roller 41 in order to be held tightly. The plate-shaped article A, worked at a work post 10, proceeds pushing up a guide 71 when it reaches a guide position 7. Even after the end A1 of the article A passes the hold by belt 35 and 36, the article A continues to proceed properly to reach the second conveyor 5, because it is still pushed against the belt 35 via the guide 7 owing to suitably set force of a spring 73. The second conveyor 5, directed by a logical control unit, carried on the article up to a receiving table 8 when so specified, while it conveys the article A toward the right side, when the article must be returned up to the entrance 2, by rotating driving rollers 51 and 52, in anticlockwise direction.
