Title: Method for measuring flow rate
Inventor: TAKAHASHI FUMIO
IPC: G01P5/00
Filed: 1983-08-10
Abstract: PURPOSE:To enable determination of a two-dimensional flow rate distribution at a high speed with simple software by storing periodically the information on particle groups into a sheet of an image memory and subjecting the same to Fourier transform. CONSTITUTION:A fluid contg. particles is contained in a water tank 1 and the image thereof is picked up by a television camera 2. Positive and negative pulse trains are generated by a predetermined number from a clock pulse generator 8 according to the signal from a controller. An A/D converter 3 digitized the image for one image plane when the positive or negative pulse is generated. The digitized image data is added and stored successively in an picture memory 5. A coder 4 gives positive and negative codes to the image data according to the positive and negative of the pulse. Therefore the image of the water tank contg. the particles is written into the picture memory by the certain positive pulse and the image of that time is subtracted by the succeeding negative pulse. The image of a static object such as the water tank or the like is canceled and only the images 10 of the moving particles is given the positive or negative code and line up at intervals along the track.

A microcomputer 7 is incorporated to the truck 2 to secure the automatic drive of the truck 2 along the band 1. Furthermore a drive path sensor 9 is added for detection of a code plate set along the band 1 and for discrimination of the juncion, etc. Then an alarm transmitter 10 and a alarm receiver 11 check an alarm and a truck passing through the junction. Thus the truck 2 is driven on a drive route stored in the computer 7 and detected by the sensor 9 at the junction. Then the truck 2 passes through the junction while transmitting 10 alarm in case no alarm is received 11 from other trucks.

Abstract: PURPOSE:To remove a foreign article even if the foreign article is adhered to a light, emitting element or a light detecting element by moving a cleaning member by means of the flow of a liquid between a light emitting surface of the light emitting element and a light detecting surface of the light detecting element to scrub the surfaces. CONSTITUTION:A cleaning member 34 is provided which is moved by means of a liquid flow 32 between a light emitting surface of a light emitting element 28 and a light detecting surface of a light detecting element 29 to scrub both surfaces. The member 34 is constituted of a wiper member 37 and a cleaning pad 38 so as to oscillate in a direction of the liquid flow 32. A liquid receiving plate 39 is fixed to the member 37, to which the liquid flow 32 collides at right angles. When a developer liquid is discharged from a developer liquid discharge nozzle 31 thereby to generate the liquid flow 32, the plate 39 is pushed by the developer liquid forming the liquid flow, and the member 37 is turned around a shaft 36. At this time, both pads 38 move while sliding in touch with the light emitting surface of the element 28 and the light detecting surface of the element 29. Therefore, foreign articles such as toners, paper dust or the like adhered to the surfaces are scraped and cleaned.

Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To eliminate frame residual images and to output the monitor information of higher quality by scanning at least once the same pixel of a photoelectric conversion part for each one to the field frequency in video camera mode. SOLUTION: In an electronic camera mode, a drive circuit 81 is connected to a signal-processing circuit 31 by an electronic switch 701. In a video camera mode, a drive circuit 82 is connected to the circuit 31, and a field is read out. The deterioration of vertical resolution can be reduced in the video camera mode through the pseudo-interlace scanning. In this case, it is desirable that both the luminance and chrominance signals by a two-wire simultaneous read signal itself be produced. That is, only the pixel signal that has been scanned and reset at each field be used as the output of a photoelectric conversion part 1. Furthermore, the signal that is once reset in every field period is used to obtain a picked up image, whose residual image has been eliminated.

Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To dispense with a holding mechanism that temporarily retains a waste can by designing the pressurizing part of a can-crushing press frame to have the height for crushing only one waste can. SOLUTION: Waste cans and the like are thrown in from the feeding port 14 of a waste can crusher 10. They are placed on the plate 16a of a bottle/can sorting mechanism. Since the bottle or the can with contents remaining inside are heavy, they fall by turning the plate 16a against the tension of a coil spring of the plate 16a and are discharged from an opening. The waste can falls on the bottom 12b of the frame. With the fall of the waste can detected, the pressurizing part 26b of the press frame moves to the right, crushing the waste can between the frame and a press plate 19. The pressurizing part 26b retreats, with the crushed waste can discharged from the opening. Assuming that the diameter of a large and small cans to be D, d and that the height of the pressurizing part 26b to be H, the formula is set as D/2<H<d/2+d(d<D<3d).  In the commercially available product, D=70 mm and d=50 mm.

Title: A/d converter
Inventor: YOTSUYANAGI MICHIO
IPC: H03M1/14
Filed: 1987-06-10
Abstract: PURPOSE:To simplify the parts of a control system and an adder by finding the high-order three bits and low-order three bits by performing A/D conversion twice, adding them together while they overlap each other by one bit, and obtaining an output code from the 5-bit conversion result. CONSTITUTION:This is a series-parallel type A/D conversion system which converts the low-order digit bits within the range of the 2LSB of the high-order digit bits and adds the high-order and low-order digit bits in one-bit overlap relation to obtain the A/D conversion result. When the high-order and low-order digit bits are converted by the same parallel type A/D converter, it is not necessary to decide whether or not the input of the parallel type A/D converter is originally 0 at the time of the A/D conversion of the final stage if a parallel type A/D converter which outputs a value that is 1LSB smaller than an actual conversion result is used. The control system and adder are therefore simplified.
