Title: Ink jet plotter
Inventor: MIZUNO AKINORI
IPC: B41J2/175
Filed: 1978-12-21
Abstract: PURPOSE:To obtain printed images of a stable qulaity by detecting the viscosity of ink, which is recovered and recirculated for reuse, to add water thereto as necessary, whereby the viscosity of ink can be maintained at a level in a predetermined range, and the ejection characteristics of ink displayed at an ink jet head can be kept constant. CONSTITUTION:A means 13 for detecting the viscosity of ink and a water supply means 14 are provided in an ink circulation system 11 which include an ink tank 2, an ink supply pump 3, a pipe 12, a head 5 and a gutter 10. Vacuum occurs at an opening of a transparent bias pipe 15, which is connected between the tank 2 and pipe 12, due to the flow of ink so that the ink in the bias pipe 15 is sucked into the pipe 12. However, when the viscosity of ink is increased, the ink in the bias pipe 15 is not sucked into the pipe 12. When this occurs, it is detected by a light emitting element 17 and a light receiving element 18, and a signal from the light receiving elememt 18 is subjected to judgement by a comparison circuit 19 and a water supply circuit 20. A signal representative of the result of the judgement, i.e. a signal for operating a water supply pump 22 is sent to the same pump to supply the water in a water tank 21 to the ink tank 2.

Filed: 1987-06-30
Abstract: PURPOSE:To improve the off-track to 45 deg. by using a tracking device generating a tracking error signal so as to select the ratio of sum between a difference component of signal crosstalk components from both adjacent tracks and a difference component between crosstalk signal components from right adjacent tracks as other than 1:1 so as to remove the dispersion in the width of head, sensitivity and recording level or the like. CONSTITUTION:After a differential signal output 23 of an operational amplifier 17 of a tracking error signal generating circuit of a tracking device is fed to a differential signal amplifier 35, a differential signal amplification output 36 is fed to a summing amplifier 29. Then an output R-H of the amplifier 17 at a point of time when a 3rd sampling pulse 31 is outputted is amplified into A(R-H) by the amplifier 35 so that a signal (24d) of (R-L)+A(R-H) being a tracking error signal is made zero at an off-track of nearly 45 deg.. Then the tracking is applied so that the signal (24d) is made always zero, thereby realizing the control that the track deviation of nearly 45 deg. is caused in average.

Title: Key input control system
Inventor: YOKOYAMA YOSHIAKI
IPC: G06F3/02
Filed: 1982-09-17
Abstract: PURPOSE:To improve the reliability for input of data, by discriminating whether an input with a ten-key or an input with an alphameric keyboard, to enabling the input of a discriminated device and to invalidating the input given from another device. CONSTITUTION:A control signal is sent to a decoder 6 from a controller (not shown in the diagram) via an address bus 7. The decoder 6 decodes the control signal and then generates outputs (a) and (b) to activate and inactivate encoders 4 and 5 respectively. When either an alphameric key 2 or a ten-key 3 is operated, the coordinate position of the operated key is detected by an activated encoder and coded to be supplied to a data bus 8. Therefore, the inputs sent from keys which are connected to inactivated encoders are all invalidated. In such a way, the function of a character key needed for a data item to be fed is selectively controlled. This improves the reliability for input of data.
