Title: Display unit
Inventor: IZUMI MAMORU
IPC: G09F9/37
Filed: 1990-10-31
Abstract: PURPOSE:To display images with sufficient contrast without using such a light source as a backup light by directly changing the color of a picture element region. CONSTITUTION:While no voltage is applied to a piezoelectric plate 23 silicon appears black when seen from a glass surface 21. When a voltage is applied to a specified piezoelectric plate 23 the piezoelectric plate 23 tends to shrink in its radial direction but because the plate 23 is joined to a diaphragm 22 the plate 23 is deformed into the shape of a concave and so a liquid 30(white) overflows a microhole 12a and swells in the empty space of a recessed portion 11a. Since the wall surface of the recessed portion 11a is acute, the whole area is made to appear white by reflection at the wall surface even though the liquid 30 does not fill the space of the recessed portion 11a. The colored liquid 30 (the color image is of plural colors) is allowed into and out of the recessed portion 11a by driving of the piezoelectric plate 23 whereby pictures and characters are displayed by combination of picture elements.

Title: Image forming method and image forming device using the same
Inventor: KATO SHUNJI
IPC: G03G15/00
Filed: 1994-11-29
Abstract: PURPOSE: To recover image density in the early stages by resetting toner end display and an image forming processing-unfeasible state set when the remaining quantity of toner is insufficient in accordance with the density of a patch image formed with supplied toner. CONSTITUTION: When the ratio of a density detection signal for the toner image of a reference density of reference density plate on a photoreceptor drum to a toner density detection signal for the surface part of the photoreceptor drum is larger than a specified reference value, a control part 48 turns on toner supply clutches 49 and 50, thereby a toner supply roller is rotated for a specified time so as to supply the toner to a developing part. When the ratio of the density detection signal calculated again after supply is larger than the reference value, the control part 48 performs a toner near end display and the image forming processing is set to the unfeasible state. Furthermore, toner supply action is continuously performed plural times so as to discriminate whether or not the ratio of the density detection signal is equal to or larger than the reference value.  When it is not equal to or larger than the reference value, the toner end display and the image forming processing action unfeasible state are reset.

IPC: H01L21/3205
Filed: 1988-11-22
Abstract: PURPOSE:To prevent peeling of a metal film by forming irregular parts at the side wall of a removed part, e.g., a contact hole or the like, which is formed by selectively removing insulating films. CONSTITUTION:The etching rate of a fourth insulating film 9 is made higher than those of second and third insulating films 4 and 5. The etching rate is suitably selected by combining different materials or changing the density by a film forming method and a forming temperature. Then holes are selectively provided in the second, third and fourth insulating films 4, 5 and 9 by photoengraving and etching. Thereafter, isotropic etching is further applied, and a contact hole 6 is formed. The etching amount of the fourth insulating film 9 is large: An end surface 7c of the fourth insulating film 9 is depressed at the side wall of the contact hole 6 and overhangs at the other parts to form irregularities in this shape. Then, a metal film 8 is formed. The metal film 8 is engaged with the second, third and fourth insulating films 4, 5 and 9 so as to conform to the irregularities. Therefore, peeling is prevented by the pressing with the third insulating film 5.

Filed: 1986-12-11
Abstract: PURPOSE:To form a sensor which is superior in airtightness, chemical resistance, and mass-productivity by forming films of titanium, platinum, and gold on a glass pedestal 2 successively, sealing the other surface with a pressure sensor wafer electrostatically, and soldering a cut chip to a base. CONSTITUTION:The titanium film 12, platinum film 13, and gold film 14 are formed successively on one surface of the glass pedestal 2 and the pressure sensor wafer 16 where a diaphragm is formed is adhered to the other surface of the pedestal 2 by an anodic bonding (electrostatic sealing) method. This joined body is cut into chips, which are soldered to the base. Thus, titanium, etc., are used, so a metallic film does not deteriorate, the anodic bonding is possible, and no resin adhesive is used, so that the pressure sensor which is high in airtightness and strong in chemical resistance is obtained. Further, the solder adhesion to the base is employed, so the overheating time is much shorter than that of glass adhesion and the mass-productivity is improved.

Filed: 1999-10-18
Abstract: PROBLEM TO BE SOLVED: To provide an image output device that can easily and accurately correct offsets of connected edges of pictures that are separately read by a plurality of number of times. SOLUTION: An image processing section 4 corrects offsets of connected edges of pictures that are separately read by a plurality of number of times by detecting to which order from a tip of a dot string a first black dot corresponds by counting the tip of a dot string of connection edges of each of image data and calculating a correction value of the offsets of the image on the basis of the difference of the detected value among the images. Then the image connection edges can be corrected with simple control. Moreover, since the correction is made also for a longitudinal direction of the original, duplicate data in the connection edges of the image data can easily be eliminated.

Title: Stabilizing device for steering during high speed running for heavy load vehicle
Inventor: YAMAGUCHI MASAYOSHI
IPC: B62D5/07
Filed: 1985-12-24
Abstract: PURPOSE:To smooth control of steering, to stabilize control during high speed running steering, and to improve reliability, by adding a control valve which limits a steering flow rate to a total hydraulic type power steering device only during high speed running steering. CONSTITUTION:During high speed running steering of a heavy load vehicle, the three solenoids of electromagnetic hydraulic valves 2, 2', and 7 are switched to ON. It is selected by vehicle characteristics or a cost whether the switching is effected by automatic switching by means of a conversion electric signal at a specified car speed or more or manual button control. In which case, a flow rate of oil discharged from a pump 10 is limited by a constant flow rate control branch valve 8, and as a result, high speed steering control of a total hydraulic type power steering device 4 is prevented. For example, when an electromagnetic valve 7 is brought into an OFF-state, relation to a flow rate by which a steering maximum speed Nmax is increased to 120rmp, the electromagnetic valve 7 is brought into an On-state during high speed steering to limit Nmax to 30rmp. As a result, steering control is further smoothed, and stabilized.
