Abstract: PURPOSE:To transfer a sheet without inclination or lateral deflection by forming a resilient body to set a sheet transfer force as a combined force of a partial force to move the sheet toward a sheet guide member with a partial force to move the sheet in the sheet transfer direction. CONSTITUTION:A sheet 13 as a subject matter of transfer is pressed to an opposite surface to a vibrator fixing surface in a resilient body 20 where a vibrator 19 is fixed, and a frequency voltage is applied to the vibrator to form a progressive vibration waves in the resilient body 20, so a transfer force is applied to the sheet 13 through the vibration surface of the resilient body 20 where progressive waves are formed to transfer it.

The sheet 13 is thus pressed forcedly to the sheet guide member 21 while it is transferred to be guided to the guide member 21, thereby the inclination and lateral deflection of the sheet 13 are corrected.

Filed: 1986-07-10
Abstract: PURPOSE:To perform focus detection with a good S/N ratio all the time by providing the 1st process wherein the number of arithmetic picture elements as objects of correlative arithmetic is varied according to relative displacement and the 2nd process wherein the number of picture elements is made constant. CONSTITUTION:The number M of arithmetic picture elements can be varied in a subroutine 'WPRED' according to a relative displacement quantity K, but the number is fixed to NNPX in a subroutine 'NPRED'. This results from that outputs of part of a sensor array SA is used in 'WPRED' although all picture element outputs are used for arithmetic in 'WPRED'. The 'WPRED' computes the same image signal by a proper processing system if a detected image shift quantity is improper for the current process on condition that the 'NPRED' is applied almost at the time of focusing when a defocusing quantity is large. Then, an image shift quantity employed for lens control is computed by the 'WPRED' when the defocusing quantity is large or by 'NPRED' almost at the time of the focusing eventually, thereby improving the focus detection accuracy.

IPC: B60L50/16
Filed: 1994-07-14
Abstract: PURPOSE:To reduce the number of switching operations of an inverter part by securing the width of the maximum value and the minimum value of a predetermined primary flux linkage in such a way that the locus of a primary flux linkage vector becomes a hexagon and selecting the switching-voltage pattern of the inverter part. CONSTITUTION:In a latch circuit 26 which is installed at a switching-pattern selection circuit 7, the magnetic-flux declination region of a primary flux linkage obtained from a magnetic-flux declination computation device 23 is input as 3-bit data, and the output of a magnetic flux comparator 24 becomes the enable signal of the latch circuit 26. By the enable signal, pieces of input data (D1 to D3) are latched respectively on 3-bit output sides (Q1 to Q3). Consequently, when the magnetic-flux-declination region of the primary flux linkage is changed over, the maximum value of the primary flux linkage is selected to be large, and the width of the minimum value and of the maximum value of the primary flux linkage is selected to be large. Then, the track of the primary flux linkage becomes a hexagon, and the number of switching changeover operations of an inverter 3 can be reduced.
