Title: Reduction gear for electric power steering
Inventor: KATA KATSUKUNI
IPC: B62D5/04
Filed: 1986-07-08
Abstract: PURPOSE:To prevent the shock and noise from occurring at the time of start by arranging two planetary gears and two ring gears rotatable by an amount corresponding to the backlash in parallel in the axial direction and providing springs applying initial loads in opposite directions to the ring gears. CONSTITUTION:Since ring gears 6, 7 are applied with initial loads in opposite directions during the rotation of a sun gear 3, directions to remove the backlash are also opposite. When the ring gear 6 is applied with an initial load in the direction from the surface to the back face and the ring gear 7 is applied with an initial load in the opposite direction and the sun gear 3 is rotated in the arrow 34 direction, a planetary gear 4 brought into pressure contact with its tooth face is rotated in the arrow 35 direction to transmit the rotating torque. A planetary gear 5 does not transmit the torque and is only rotated following the planetary gear 4. When the sun gear 3 is rotated in the opposite direction to the arrow 34 direction, the gear 5 alone transmits the torque, and the gear 4 is only rotated in pursuit. Tooth faces of the planetary gears and brought into pressure contact with the sun gear and ring gears, thereby the shock and noise caused by the backlash can be prevented from occurring.

Title: Image forming machine
Inventor: TANAKA YOSHIHISA
IPC: G03G15/00
Filed: 1995-06-27
Abstract: PURPOSE: To extremely reduce or prevent the generation of a processing noise, even if any transfer paper is used by setting the paper feeding speed of a transfer paper supplying means faster than a carrying speed with a transfer paper carrying means carrying the transfer paper through a transfer area. CONSTITUTION: A forward feeding roller 30 corresponding to a transfer cassette 26, a pair of processing rollers 34 and a pair of feeding rollers 38 are driven and an electromagnetic spring clutch is energized to rotationally drive a feeding roller 37 at a first feeding speed the same as the feeding speed of each of these rollers. Thus, the respective rollers 30, 34, 38 and 37 are rotationally driven and an A-3 transfer paper for only a color copy housed in the cassette 26 is fed toward a pair of resist rollers 46.  The feeding speed of the transfer paper by these rollers is faster than the carrying speed by the transfer paper carrying means 45, so that even if the A3-transfer paper for only the color copy generating the processing noise very much, at the time of passing through the processing roller 34 is used, this image forming machine is set so that the processing noise is very low. Thus, even when other transfer papers are used, the processing noise is not generated.

Title: Integration circuit and digital camera

IPC: H04N5/235
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To provide an integration circuit capable of easily calculating an integration value not affected by change of the number of pixels. SOLUTION: The pixel number of a CCD imager adopted in the digital camera of a previous time is defined as 350,000, and the pixel number of the CCD imager 12 adopted in the digital camera 10 of this time is defined as 810,000. Then, in this integration circuit 15, Y data are integrated over one frame period first, and then integration data are multiplied by 35/81 by an arithmetic circuit 24. That is, while the Y data are simply integrated in the digital camera of the previous time, in the digital camera of this time, the Y data are multiplied by 35/81 after integration. As a result, in the camera of photographing the same object, the same integration data are outputted from the integration circuits of both digital cameras. Thus, since an arithmetic operation, for which the pixel number of the CCD imager of the previous time and the pixel number of the CCD imager of this time are taken into consideration, is executed for the integration data, the effect of the change of the pixel number is removed from the integration data.
