Filed: 1990-07-31
Abstract: PURPOSE:To raise and lower a sheet stacking plate only by the rotation and removal/attachment of a tray by providing rise guide members for vertical and horizontal feed on a rotating tray, and operating a rotating bar by rotation to raise and lower a lift plate. CONSTITUTION:A rotating tray 4 has rise guide members 55, 56 for vertical and horizontal feed, and when the tray 4 is rotated in either of both the positions, the rotating lever 41 of a driving system 33 provided in a receiving box 3 is rotated to engagingly lock a pin 46 with the upper end of an elliptic hole 36, and the other pin 45 is engagingly locked with the end of an elliptic hole 35. When the tray 4 is installed in this state, the roller 50 of a rotating lever 40 having one end pivotally fixed to the pin 45 is guided by the guide of a body, the lever 40 is rotated with the pin 45 as the center, and a spring 54 is stretched through levers 42, 43 to raise a lift plate. Thus, a sheet stacking plate 25 is raised. The stacking plate 25 thus can be raised and lowered only by the attachment/removal and rotation of the tray.

Filed: 1982-11-26
Abstract: PURPOSE:To inspect a defect, detect heterogeneous light, improve inspection sensitivity and thereby defect a minor damage by detecting disturbance of deflected light due to the defect of mask through irradiation of glass mask with the deflected light. CONSTITUTION:A general light 9 emitted from a laser source 4 changes to the deflected light 10 when it transmits through the first deflecting plate 5. Then, it enters the glass mask 1 at a right angle and transmits to the upper direction. The deflected light 10. When the deflected light 10 transmits the damage-free area of glass mask 1, it transmits only in the direct vibrating direction. Since the light is shielded by the second deflecting plate 6, a light sensor 8 does not detect the light in such amount larger than the specified one. The deflected light 10 contains the light 11 in the other vibrating direction when it transmits the flaw 2 of glass mask 1. This light 11 transmits without any shielding by the second deflecting plate 6, and then transmits the slit plate 7 and is detected by the light sensor 8.

Operation  time is taken into consideration so that circumferential lengths LP, LK for the new and the old rolls of paper are determined as LP=V.TP+LM and LK=V.TK-LT. To cause  the press 13 to act, a preset timer circuit 8 is put in operation by a gate signal T1 so  that a preset counter circuit 9 receives a frequency FLP after the lapse of time TP and  starts substraction with a margin length LM. The subtraction is replaced with addition  by a signal T2. The addition is stopped by a signal T3. Throughout the generation of  the signal T3, a result of measurement is used as a latch output and the content of the  circuit 9 is denoted by the formula LP. For the action of the knife 14, the quantities  TP, LM in the calculation for the action of the press 13 are replaced with those TK, LK  so that addition and subtraction are replaced with each other.

Title: Liquid injection and discharge type matrix optical waveguide switch
Inventor: MAKIHARA MITSUHIRO
IPC: H04Q3/52
Filed: 1991-08-19
Abstract: PURPOSE:To improve the reliability of a liquid injection and discharge mechanism and to facilitate the control of liquid quantity by providing a projection to each liquid pool of a matrix optical waveguide switch to relax the positioning accuracy of a liquid injection device. CONSTITUTION:When a liquid 23 is pressed by a pump or the like to inject the liquid 23 to a liquid pool 6, a spherical liquid drop 23a is formed to a tip of a very fine tube 19. The liquid drop 23a is in contact with a projection 7 provided to the liquid pool 6. The liquid drop 23a in contact with the projection 7 is spread over a bottom face of the liquid 6 via the projection 7 by the surface tension and when the liquid 23 is in contact with a side wall of the liquid 6, the liquid is naturally injected in a groove 5 along the side wall. Thus, when the liquid 23 is filled in the groove 5 and the liquid pool 6, an optical signal SI made incident from an optical waveguide 2 for an input optical signal is not reflected in the side wall face of the groove 5 but is transmitted in the groove 5 straightforward. Since the projection 7 in the liquid pool 6 has almost the same height as the surface of the matrix optical waveguide switch 1, the liquid is injected without inserting the very fine tube 19 into the liquid pool 6. Thus, the reliability of the liquid injection and discharge mechanism is improved.
