Filed: 1980-08-22
Abstract: PURPOSE:To prevent a printed point from being displaced under the effect of airflows generated in company with the rotation of a rotary drum, by placing windshield plates in the proximity of the drum, in an ink jet recorder. CONSTITUTION:Below the printed point P, a plurality of windshield plates 9-11 are placed in the proximity of the rotary drum 1 and in such a manner as to be normal to the outside peripheral surface of the drum 1. The windshield plates 9-11 are fixed to a back plate 12 and shield the airflows 13 which are generated in the vicinity of the outside peripheral surface of the drum 1. Therefore, a calm condition is maintained between the head 3 and the printed point P, enabling the ink droplets 7 jetted from the head 3 to be printed correctly at the printed point P. In addition, when windshield plates slightly longer than the lateral width of the head 3 are placed above and below the head 3, external disturbing airflows can also be shielded effectively. Accordingly, it is possible to prevent the flight of ink droplets from being disturbed by airflows, which might otherwise cause disturbance in recording or a mismatching of colors in color recording.

Filed: 1983-06-28
Abstract: PURPOSE:To prevent the transmission of wrong signals and to improve the reliability of an interface circuit by delivering a state signal from the 1st means after checking whether the power supply voltage is higher than a prescribed level or not. CONSTITUTION:A controller 1 of a microprocessor, etc. is connected to the input terminal of a gate IC1 consisting of a TTL IC of an open collector for example. At the same time, a power supply terminal is connected to a power supply VCC and an output terminal is connected to the base of a transistor TR1 via a resistance R1 and a Zener diode ZD. A resistance R2 is connected between the emitter and the base of the TR1, and at the same time a collector output is connected to an integrated circuit IC2 via a resistance R3 and a transmission circuit 2.

Title: Vibration tape load measuring instrument
Inventor: NISHIGUCHI YUZURU
IPC: G01G3/16
Filed: 1986-05-20
Abstract: PURPOSE:To make variation in obtained vibration frequency proportional to a load to be measured and to take a measurement with high accuracy by increasing or decreasing the ratio of the transmission of the load to be measured to a vibration type sensor at a constant rate corresponding to an increase in the load. CONSTITUTION:When the load W is placed on a measuring pan 6, a ring spring 11 expands and horizontal links 3 and 4 slant by an angle theta, so that a movable column 2 is displaced down perpendicularly by (y) which is nearly equal to L.theta. At this time, part of the load W, i.e., force k.y proportional to the displacement (y) is absorbed by the spring rigidity of the flexible part 5 of a link mechanism and not transmitted to a tuning fork vibrator 9. One end of the vibrator 9 is held by a link spring 11 which has non-linear characteristics, so the ratio k.y/W of the force k.y absorbed by the link mechanism to the load decreases as the load W increases. Consequently, the ratio F/W of axial force F transmitted to the vibrator 9 and the load W increases and the relation between the load W and variation DELTAf in oscillation frequency is made linear.

The difference in the coupling degree by the polarized wave is eliminated in this way and the high performance is obtd. The application of the coupler to all the polarized wave maintaining optical fibers is thus possible.

Abstract: PURPOSE:To improve the circuit quality by transmitting the signal having a level down and detected by a reception system when a desired wave has a level down due to the difference of transmission lines to the transmission system of a counter station and changing the transmission output of the counter station. CONSTITUTION:The information on the level difference between a desired wave and an interference wave received from a counter station via a service channel is taken out by a demodulator 18 and processed by a control circuit 21.
