Title: Ink jet head
Inventor: KATAOKA MASAKI
IPC: B41J2/175
Filed: 1993-06-18
Abstract: PURPOSE:To provide an ink jet head which can retain the ink pressure in an ink tank almost constant by a simple structure and also provide the good printing quality. CONSTITUTION:Ink is fed from a porous body 3a in an ink tank 3 to a recording head 2 through a communication line 8 and a manifold section 5. The ink tank 3 is communicated with the atomosphere outside the ink tank by an air communication hole 6 with a pressure control valve 7 having a slit on an elastic component. When printing is carried out and ink is consumed, the pressure difference between the atmospheric pressure and the pressure in the ink tank 3 is increased to open the slit of the pressure control valve 7 and feed air into the ink tank 3. When the pressure difference is decreased, the slit is closed. The internal pressure of the ink tank 3 is controlled in the negative pressure range having the given width by repeating said operation. The ink retaining rate of the porous body can be improved by using the porous body of low density.

Title: Color image forming device
Inventor: HIROSHIMA KOICHI
IPC: G03G15/01
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To attain the improvement of usability and operability by eliminating a toner image wastefully formed and suppressing the wasteful consumption of toner and toner scattering by detecting the quantity of a transfer material held and changing an image forming interval formed on a second image carrier based on information. SOLUTION: The residual amount of the transfer material (paper) P is detected at the inside of a cassette 14 by a paper existence/absence sensor 15, and the image forming interval formed on the intermediate transfer belt 6 is changed at the point of time when the residual amount of the paper becomes less than the specified number of sheets, so that the wasteful toner consumption is evaded. Thus, for instance, a distance between images may be >=270 mm whereas plain paper throughput is set as letter size lateral (216 mm) feed/24 ppm and the image forming interval is set as 84 mm. Thus, the distance between the images is changed to a specified distance (270 mm) by changing a laser exposure writing timing controlled by a CPU for a main body control at the point of time when the residual amount of the paper becomes less than a specified level, so that the throughput is changed.

Title: Printed wiring board
Inventor: MURAI AKIRA
IPC: H05K3/40
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To put the thermal expansion coefficients of an electronic component and a printed wiring board at approximate values, by forming terminal plugs for surface mounting so that they may be orthogonal to the direction of threads where the weave density is large. SOLUTION: For example, in a cloth 0.1mm thick, a laminate where glass cloth base material is lined with copper is manufacture, using the glass cloth which is woven so that the threads ma be sixty five pieces in longitudinal direction and fifty five pieces in lateral direction, or sixty seven pieces in longitudinal direction and fifty pieces in lateral direction, as regards the area of 25mm square. This way, a printed wiring board for mounting electronic components is manufactured, using a material for a laminate lined with copper which is manufactured, with the glass cloth, where the weave density is different between the longitudinal direction and the lateral direction, as the base material. At that time, the arrangement of all the terminal plugs of electronic components is designed so that it may be orthogonal to the thread in the direction where the weave density is high.  Hereby, the thermal expansion coefficients of the printed wiring board and the electronic component are made approximate values, by which the reliability on connection of the terminal plugs can be improved and also the yield in mounting can also be made good.

Title: Control system of color ribbon
Inventor: IDOUJI SHIGEKI
IPC: B41J35/14
Filed: 1985-08-07
Abstract: PURPOSE:To conduct color mixture printing by using a color mixture band, and to reduce the fouling of single color printing by dividing a color ribbon into a monochromatic band for single color printing and the color mixture band exclusive to a color mixture with another color mixture and mounting the color ribbons. CONSTITUTION:Color mixture bands are formed after each blue, red and yellow monochromatic band, and only the ribbon bands are used on a color mixture. Consequently, the monochromatic bands are not fouled on the color mixture. As a result, seven ribbon bands are shaped, but printing can correspond to the seven ribbon bands sufficiently by changing the quantity of control of a ribbon shift mechanism. Discrimination between the monochrome and color mixture of a color-designating command in processing commands from a CPU 22 is detected; the quantity of a shift up to the monochromatic band of a designated color from the present position of a ribbon is computed in case of the monochrome, and a ribbon shift is executed by employing the ribbon shift mechanism and printing by a head 3 is conducted. Accordingly, even when bands are shifted to the monochromatic bands from the color mixture bands, the monochromatic bands are clean at all times and are hardly fouled even when bands are transferred to the same monochromatic bands.

Abstract: PURPOSE:To form an optical waveguide, of which surface roughness is so low as to make the loss of the optical transmission small, by applying the ion impact treatment to the surface of a dielectric substrate previously at the time of forming an optical waveguide on the surface of a dielectric substrate with the thermal diffusing method. CONSTITUTION:The material having the effect for improving the refraction index of a dielectric is deposited for adhesion on the surface of a dielectric substrate, and this material is diffused by heating near the surface of the substrate to form an optical waveguide. At this stage, before the adhering process, ion impact treatment is applied to the surface of the substrate in the atmosphere of the gas including the rare gas ion. With this treatment, the imperfection of crystal and the deterioration of quality is thereby improved in the surface of the dielectric substrate. The material for improving refractive index is diffused inside of the dielectric substrate by the thermal diffusing processing to be performed continuously through the surface improved layer. Simultaneously, imperfection and deterioration of the surface of the dielectric substrate are restored to the normal condition to form an optical waveguide having the excellent surface condition, for example, having the smooth surface.

IPC: B62D6/00
Filed: 1999-06-21
Abstract: PROBLEM TO BE SOLVED: To restrain the irregular behavior of a vehicle caused by the external disturbance of a lateral wind without requiring a driver's possitive steering by acting an auxiliary reaction torque to the direction restraining a vehicular behavoir to a running wheel regardless of the existence/absence of a driver's steering. SOLUTION: The auxiliary reaction torques T1, T2, T3 for respective components are found out, by making each of a steering angular velosity ω, lateral acceleration G and yaw rate γ to an address, from respective data tables set per a car speed V (S21-23) and they are added (S24). Further, the auxiliary reaction torque more than needed is removed (S25) and a target auxiliary reaction torque decision value TA is decided. Thereby, when the yaw rate γ or lateral acceleration G are generated to the vehicle by the external disturbance such as the lateral wind, a front wheel is steered automatically so as to always running the vehicle straightly for the external disturbance and the irregular behavoir can be stabilized.
