IPC: B41J11/42
Filed: 1990-11-09
Abstract: PURPOSE:To enhance the quality of an image by providing an optical sensor for detecting a position for a printed image printed on a sheet, on a print head. CONSTITUTION:An optical sensor 19 for detecting a printed image printed on a sheet 16 is installed outside the nozzle 17 of a print head 10. Then if an image equal to a single line ends, the print head 10 is activated due to a carriage return action, and in this case, a line is already fed. Therefore, a position for the lowermost dot of a printed image in a preceding line is detected by an optical sensor 20. This detection signal is connected to an arithmetic operation part 25 to calculate the amount of fed lines. That is, a distance between a position for the lowermost dot of a preceding line detected by the optical sensor 20 and a position for the uppermost dot of a printed image to be printed in a following line is determined. If the distance is short, a line feed control part 24 is controlled, so that an interval between fed lines becomes wide. If the distance is long, the part 24 is controlled so that the interval becomes narrow. Subsequently, the interval between fed lines is corrected. It is recommended that the basic interval of a line feed motor 15 for correction be about 1/2 to 1/5 of a dot interval on the print head 10.

Title: Fine airtight container and its manufacture
Inventor: SAKATA JIRO
IPC: H01L29/84
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To obtain a manufacturing method of a fine airtight container which can realize high vacuum degree. SOLUTION: A polycrystalline silicon film 21 which becomes a sealing member is formed by using SiH4 gas. Since the gas is active, it reacts on H2O. After the polycrystalline silicon film 21 is formed, the gas remaining in a space part 15 and H2O remaining in the space part 15 are made to react. According to this reaction, H2 gas and nonvolatile SiO2 are generated. A polycrystalline silicon film has a property to allow H2 gas to pass through at a high temperature. Accordingly, H2 gas inside the space part 15 is emitted to an outside through the polycrystalline silicon films 11, 12 by heating the polycrystalline silicon film 21 under high vacuum. As a result, high vacuum of the space part 15 can be realized.

Title: Ink jet recording apparatus
Inventor: AMEYAMA MINORU
IPC: B41J2/05
Filed: 1988-12-02
Abstract: PURPOSE:To reduce emitting energy by providing a narrow passage part having a cross-sectional area wider than that of a narrow passage part in an emitting orifice direction so as to continue to said narrow passage part. CONSTITUTION:When a voltage pulse is applied to one of electrodes 5, 6, a current flows to the ink 4 in a flow passage 3 and narrow passage parts 7, 7' but, since the current density of the narrow passage parts 7, 7' is high, the ink 3 in said parts generates heat and an air bubble 8 is generated from the narrow passage part 7. The air bubble 8 covers the narrow passage part 7 and cuts off a current but said air bubble is ready to further expand by the heat stored in the ink 4. The air bubble 8 expanding toward a common liquid chamber 2 is cooled because the temp. of the ink 4 in the flow passage 3 hardly rises and prevented from expansion but, since the expanse part 7' of the narrow passage part in the direction of an emitting orifice is considerably in high temp., the expansion of the air bubble 8 is not obstructed. Therefore, the expansion of the air bubble is performed toward the emitting orifice 1. By this method, the ink is vaporized by small energy and the pressure at the time of the vaporization of the ink cap be effectively converted to emitting energy.

Filed: 1989-11-28
Abstract: PURPOSE:To measure the characteristics of a scanner at a high speed highly accurately under the dynamic conditions by using two sets of dynamic forward and backward movement measuring instruments, and directly measuring the forward and backward moving amounts which affect the rotation jittering of the polygon scanner. CONSTITUTION:Reflected light L3 of emitted light L2 from a second laser light source 3 is obtained from a first reflecting point R1 of a polygon mirror 1. The obtained light is detected with a first trigger generator 7 as the reflected light L4. Reflected light L9 of emitted light L7 from a fourth laser light source 5 is obtained from a second reflecting point R2 of the mirror 1. The obtained light is detected with a second trigger generator 9 as the reflected light L12. The time difference between the detected signal from the trigger generator 7 and the detected signal from the generator 9 is detected. Thus the jitter without the forward and backward moving components can be measured. Furthermore, reflected lights L6 and L11 of emitted lights L5 and L10 from first and third laser light sources 2 and 4 obtained from the first and second reflecting points R1 and R2 of the mirror 1 are inputted into first and second position detectors 10 and 11 through first and second cylindrical lenses 12 and 13. Thus, the forward and backward moving amounts at the first and second reflecting points R1 and R2 can be measured at the same time.
