Title: Apparatus for precisely measuring distance
Inventor: KURITA SHOICHI
IPC: G01S13/10
Filed: 1986-03-18
Abstract: PURPOSE:To make it possible to measure a distance in a range from several km to several cm, by sending out a transmission pulse having a narrow pulse width and elongating the time difference between transmitting and receiving pulses when a distance to be measured is in a predetermined range. CONSTITUTION:A detection circuit 6 compares the time difference between the transmitting pulse and receiving pulse outputted from a first time difference measuring circuit 5 with the determined time difference stored therein and drives change-over circuits 72, 82 when detects that said time difference reaches the predetermined time difference or less to send out a transmitting pulse having a pulse width narrower than that of the pulse transmitted heretofore by a second pulse generating circuit 71 to a reflecting body. A second time difference measuring circuit 81 receives said transmitting pulse to measure the time difference between the transmitting and receiving pulses. In this case, the fine sampling wave forms sampled by sampling gate circuits 84, 85 are converted to large pulses of which the cycles are enlarged by LPF 84, 85. At this time, because the time difference between the transmitting and receiving pulses is enlarged in proportion to an actual time, the time difference between both pulses can be measured by a low speed counter and measurement can be performed with high accuracy.

Filed: 1987-03-16
Abstract: PURPOSE:To enable printing of high quality to be carried out with a simple mechanism, by providing magnetic fluid to the top of a nozzle. CONSTITUTION:Ink 5 having received pressure with pressure electron parts 6, 7 passes through an energized chamber 9 and advances to nozzles 4, 3. Then, after an ink liquid drop 11 having passed through this nozzle 3 is taken into magnetic fluid 2, it further continues to move by receiving an influence of inclination of magnetic field. The ink liquid drop 11, following this movement, receives sudden energy at a point of time when the inclination of a magnetic field is strongest, and becomes uniform fine liquid drops 12, which fly to carry out printing of high quality. In that case, by centering effect to be generated when the liquid drop 11 moves in the magnetic fluid 2, the liquid drop 12 flies straight from the center of the nozzle 3. Consequently, a device for adjusting to constant a flying out direction of the liquid drop 12 one becomes unnecessary.

Abstract: PROBLEM TO BE SOLVED: To prevent a read image from causing 'out of focus' and 'black level deformation', even if a floated part such as a file margin has a thick book cast with its face down with respect to a flat bed type scanner employing a close contact sensor. SOLUTION: An unmagnified image reading CIS control section 7 discriminates that a read image is that of a file margin of a book when a white part read output value within a prescribed range is gradually decreased in the midst of reading the image of spread pages of the book plated on an original platen and allows a CLK frequency variable section 8 to decrease the frequency of a pixel clock given to a CIS 1 and allows an image processing section 3 to increase an MTF correction coefficient as its control. When the white part read output vale within a prescribed range is gradually increased, the control section 7 discriminates that the reader reads an image at the outside of the file margin of the book, and controls the frequency of the pixel clock to the increased and the MTF correction coefficient so as to restore to the original coefficient that is a value before being increased.
