Title: Method for recognizing and inspecting image
Inventor: KONISHI KOJI
IPC: G01B11/26
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To provide a method for recognizing and inspecting an image while ensuring a good recognition accuracy. SOLUTION: In the method for recognizing the inclining direction of an electronic component by recognizing the image thereof, image of the electronic component is picked up by means of a camera (ST12) and the inclination data of a vector set on the extracted outline thereof is determined in order to make an angle histogram indicative of the inclination distribution (ST13). The angle histogram is compared with a reference histogram obtained from an image picked up under a state where the electronic component is not inclining and a phase angle providing a maximum degree of coincidence between both histograms is specified and outputted as an inclination angle (ST14-ST20). According to the method, phase shift between both histograms can be detected accurately even for a small electronic component where the peak shape of angle histogram picked up by means of camera would be obscured and the inclination angle of an object can be determined with good accuracy.

IPC: G03F1/80
Filed: 1989-10-16
Abstract: PURPOSE:To eliminate the need for a resist and to simplify the process for production of a mask as well as to allow the production of the mask pattern having high accuracy by depositing a transition metal oxide as a mask material on a transparent substrate, exposing the oxide by an ion beam, etching the mask material, and further reducing the mask material. CONSTITUTION:The amorphous transition metal oxide 11 is deposited atop the transparent glass substrate 1. The deposition is executed by vacuum vapor deposition. The amorphous transition metal oxide 11 is then exposed to the prescribed mask pattern by irradiation and scanning with the ion beam 12. The entire part is then etched by an alkaline soln., such as NaOH, to remove the part irradiated with the ion beam 12. Finally, the amorphous transition metal oxide 11 is reduced in an H2 atmosphere, etc., to form the amorphous transition metal. This amorphous transition metal then becomes the photomask. Since the resist is not used in this way, the time for formation is drastically shortened and the pattern accuracy is improved.

Title: Car body upper surface washing device
Inventor: TAKEUCHI TOSHIO
IPC: B60S3/06
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To effectively reduce the force applied from a washing body to a car body upper surface when the rotating speed of the washing body is changed by setting the average changing ratio of the rotating speed small when the rotating speed of the washing body rotating in contact with the car body upper surface is changed. SOLUTION: When the rotating speed of a washing body W is reduced, a pipe member 111 situated in the rotating center of the washing body W is slightly displaced down so as to approach a car body upper surface. However, since the rotating speed change is gentle at that time, the force acting on the car body upper surface is effectively reduced in lowering and stopping even when the weight of the washing body W is significantly increased by the water content of a washing member 112 . On the other hand, when the washing body is accelerated, the pipe member 111 situated in the rotating center of the washing body W is displaced upward so as to separate from the car body upper surface. However, since the rotating speed change is gentle at that time, the force acting on the car body upper surface is effectively reduced by the upward reaction.
