Title: Driving of ink injection device
Inventor: ASAI HIROMOTO
IPC: B41J2/045
Filed: 1993-12-16
Abstract: PURPOSE:To ensure that a residual pressure variation can be cancelled using a single drive power supply and an ink is injected smoothly. CONSTITUTION:The volume of an ink chamber 4b1 is increased from its natural state by applying a voltage V to the ink chamber 4b1 and grounding ink chambers 4a1, 4c1 adjacent to the ink chamber 4b1. In addition, the volume of the ink chamber 4b1 is reduced to a state which is diminished below the natural state from the increased state by stopping the voltage V applied to the ink chamber 4b1 and instead applying the voltage V to the ink chambers 4a1, 4c1. In this case, a deviation (m) between a point of time for the start of voltage application to the ink chamber 4a1 and a point of time for the start of voltage application to the ink chamber 4c1 is made to be less than the time which is 0.3 times the time spent for a pressure wave to propagate one way through the ink chambers 4, and ink droplets are ejected from the ink chamber 4b1. Next, the residual pressure variation inside the ink chamber 4 is cancelled by stopping the application of the voltage V to the other ink chamber 4 and setting back the volumes of all the ink chambers 4 to the natural state.

Title: Magnetic disk device
Inventor: INANAGA KAZUHIKO
IPC: G11B21/21
Filed: 1989-12-06
Abstract: PURPOSE:To execute activation and stop by a magnetic disk device without contact between a slider and a magnetic disk by providing a suspension supporting mechanism to hang up a suspension so that the slider can not get contact with the magnetic disk until the rotating number of the magnetic disk reaches the prescribed rotating number. CONSTITUTION:When the device is activated and the rotating number of the magnetic disk reaches the prescribed rotating number, a support panel 7 is moved in an arrow Z direction since a bimorphe piezoelectric actuator 6 is bent. By the displacement of a suspension 3 caused by the move of the support panel 7, a slider 1 is closed to the surface of a magnetic disk 4 and between the slider 1 and the magnetic disk 4, an air film with submicron thickness is formed. Then, the slider 1 floats up even without supporting the suspension 3 by the support panel 7. After the slider 1 floats up, the support panel 7 is separated from the suspension 3 and stopped. Thus, damage is prevented from being generated by the repetition of the contact between the slider 1 and the magnetic disk 4 at the time of activation or by adsorption between the slider 1 and the magnetic disk 4 at the time of stop.

The liquid crystal pannel 30 is driven by a synthesized waveform (Xn-Ym) between a scanning electrode drive signal Xn and the signal electrode drive signal Ym. By varying the pulse height value of the drive signal Xn for each scanning electrode at every divided period, a peak voltage in the synthesized waveform (Xn-Ym) becomes higher value than as usual, and then responsiveness is quickened.

Title: Method for measuring area and number of foreign matters on surface of sheet-shaped material
Inventor: IZUMI HIDEKI
IPC: G01N21/892
Filed: 1989-12-08
Abstract: PURPOSE:To make it possible to measure the number and the areas of colored foreign matters automatically at a high speed in high accuracy by correcting the measured value of the area of the colored foreign matter in correspondence with the hue and the color density of the foreign matter when the light is projected on the surface of a sheet-shaped material and the area is measured under a photoelectric mode. CONSTITUTION:The light from a light source is projected on the specified area of one surface of a sheet-shaped material 7 which is moved with a driving motor M. The reflected light is detected with an image sensor. The signal is transduced into the electric output signal at the same time. The output signal is amplified in a main amplifier having a differential ACC differentiation circuit. The effect of noises is eliminated by making a voltage that is about twice the inherent noise voltage in the surface of the sheet-shaped material to be a threshold voltage. The output voltage corresponding to the foreign matter is detected and sent to a comparator. The peak voltage and the signal width at the threshold level are measured. The areas and the number of the foreign matters in the surface of the sheet-shaped material are computed in a central control unit CPU, displayed on a CRT and recorded with a printer 12.
