Title: Ink jet head
Inventor: FURUTA TATSUO
IPC: B41J2/045
Filed: 1990-05-16
Abstract: PURPOSE:To obtain an ink jet printer head with an excellent flatness of a nozzle-forming member by reducing the mean thermal expansion coefficient of a base on which the nozzle-forming member is fixed compared to the nozzle- forming member in an ink jet head equipped with a piezoelectric converter in the ink. CONSTITUTION:This ink jet head allows a pressure generating device in the ink to eject the ink from a nozzle opening part. The nozzle-forming member 8 of Ni is joined to a base 11 of alumina through a piezoelectric converter 2, for example. The piezoelectric converter 2 is cut into segments for nozzle openings 9. A thermal expansion stress which acts upon the nozzle-forming member 8 depends on the base 11. In addition, the nozzle-forming member 8 of Ni is junctioned to the base 11 of aluminum under applied pressure in such a state that the member 8 is heated to the curing temperature of a conductive junctioned layer 10. If the temperature is lower than a curing level, the head receives a tensile stress from the base 11 which contributes to the provision of an excellent flatness over the entire head area. Thus the head can be kept away uniformly from the piezoelectric converter.

Filed: 1990-05-18
Abstract: PURPOSE:To effectively control the drive of a vehicle in a single recursive system by changing the distance from a while line drawn on a road detected in each direction into the distance from a prescribed reference line. CONSTITUTION:An image processor 5 calculates a distance from a white line SW drawn on a road based on the images photographed by the cameras 1 - 3 and supplies the calculated distance to a visual point calculating device 7. The device 7 applies the visual point control to the distance from the received line SW and changes the distances detected by the cameras 1 and 3 which are not turned toward the center line of a vehicle into the distance of a coordinate system of a reference attitude which is coincident with the visual axis of the camera 2 turned toward the center line of the vehicle. Then the drive of the vehicle is controlled based on the changed distance. Thus a steering angle is calculated in a single recursive system regardless of the direction where the line SW is detected. Then the drive of the vehicle is effectively controlled.

Abstract: PROBLEM TO BE SOLVED: To make it possible to provide element-direction recognizable indexes simply, and to recognize the direction of an element with a high-precision without increasing the cost, by providing a plurality of conducting dotlike electrodes and a plurality of dotlike positioning indexes out of the same material for the electrodes on a surface. SOLUTION: Via hole electrodes 3-10-3-12 are only on the first layer of the uppermost layer, and conduction is not especially required. To regulate the circumferential direction of a laminated piezoelectric element, four via hole electrodes are arranged in a straight line in the order of the via hole electrodes 3-9 → 3-10 → 3-11 → 3-12 from the center of the element in the radial direction. And it becomes possible to read and judge the circumferential direction of the element from the center of the element and the straight line connecting these four via holes 3-9-3-12 with a high precision, by image processing by the use of a camera, etc., not to mention visually.  The reason why four via holes are provided here is to evade maljudgement or fear of being in a confusing state by the adhesion of dirt, etc., and the use of four holes in total is for enhancing the reliability of recognition.

Title: Monolithic foam molding method
Inventor: TAKAMATSU SHIGEKI
IPC: B29C39/10
Filed: 1987-05-25
Abstract: PURPOSE:To prevent a dry spot of a cell and a sink void by eliminating breakdown of a film, by supplying air pressure on the backside of an insert after a space between the insert, whose opening part has been closed with the film, and the skin has been filled up with a foamed body. CONSTITUTION:An insert 3 including a film 6 and the skin 4 are set up respectively on a top and bottom forces 1, 2 and mold clamping is performed by casting a predetermined quantity of a foaming stock solution over the skin 4. The roaming stock solution is foamed through heating, the inside of a foaming space is filled with a foamed body, and pressure to be applied to the film 6 is increased rapidly. As cure of t he foamed body 8 from directly after filling up of the same up to directly before complete foaming of the same is incomplete, a dry spot of a cell is apt to occur due to breakdown of the film 6. Therefore, when foaming pressure to be applied to the film 6 is offset by the air pressure by supplying the air pressure to the backside of the insert 3 through an air supply hole 7 provided on the force 1, breakdown of the film 6 can be prevented.
