IPC: G01F17/00
Filed: 1984-06-22
Abstract: PURPOSE:To detect the liquid amount in an arbitrarily shaped container without machining the container, by utilizing the fact that a resonant frequency is changed by the amount of a material in the container. CONSTITUTION:A vibrator 3 is driven by a controller 7 and a driver 6 so as to include many frequency components. The vibrations are transmitted to a container 1.

Abstract: PURPOSE:To make it possible to rapidly perform the processing of image formation by performing the forcible replenishment of toner after completing the processing of image formation at the time of discriminating that concentration detected by a toner sensor is sparser than reference concentration data and the specified number of sheets is under the reference number. CONSTITUTION:When a start signal is given from a start signal output means (printing key 19) and is received, a 1st comparison means and a 2nd comparison means discriminate the toner concentration of a developing device 4 and the number of image formation processed sheets respectively in response to the received signal. When the specified number of image formation processed sheets is less than the previously set number even in the case where the toner concentration is sparser than the reference concentration according to which the exhaustion of the toner is informed, the processing of image formation is directly executed. After completing said processing, a control means performs the control of the forcible replenishment of the toner. Meanwhile, when the specified number of image formation processed sheets is equal to or exceeding the previously set number, the control means 13 performs the control of the forcible replenishment of the toner prior to the processing of the image formation and said processing is successively executed. Thus, the processing of image formation can be rapidly performed without keeping the user waiting.

Abstract: PURPOSE:To obtain an inexpensive magnetic tape device which gives no damage at all to a tape with a miniature structure and a small number of parts, by driving both a cassette moving means and a tape draw-out means with a single driving means. CONSTITUTION:A cassette is moved up to the 2nd position to draw out a magnetic tape. For this purpose, a motor 19 is energized to revolve a worm 20. Thus gears 9, 10, 13 and 17 interlocking the worm 20 are revolved, and gears 14 and 18 are turned counterclockwise. Then cams 24 and 25 interlocking the gears 14 and 18 via springs 26 and 27 are also turned counterclockwise. Thus the shafts 22 and 23 of a cassette supporting plate 21 interlocking the cams 24 and 25 are shifted along a slit 41 (and a slit of a side plate 7). A tape draw-out member 35 is shifted to an inactive position from an active position, and then a cassette 1 is shifted to the 1st position from the 2nd position by reversing the revolving direction of the motor 19. The 1st position is detected when the cam 25 touches a switch 42. Then the energization is discontinued to the motor 19, and the cassette 1 can be freely loaded and unloaded.
