Title: Suction device for internal combustion engine
Inventor: NAKANISHI KIYOSHI
IPC: F02M35/10
Filed: 1980-10-04
Abstract: PURPOSE: To obtain the swirl intensity suitable for engin operating conditions in an internal combustion engine including a helical intake port by a device wherein a movable swirl control member is provided at the final end portion of the helical port and then varied in its position in response to the engine operating conditions.  
     CONSTITUTION: A final end portion 14 of a helical intake port 14 on the side of a combustion chamber 12 is shaped into a spiral form, so that mixture gas introduced into the combustion chamber 12 is swirled. A sliding member 18 serving as a swirl conrol member is provided at the inner wall of the final end portion 14. The sliding member 18 has at its front end an inclined surface 181 and at its rear end a negative pressure chamber 22 which is formed of a rubber member 20 adapted to enclose the chamber and which has a spring 24 housed therein to cause the sliding member 18 to move back and forth. While an engine operates at a low/middle speed and low/ middle load a negaive pressure at a negative pressure port of an intake manifold 16 is introduced into the negative pressure chamber 22 by a control device through a piping 28, so that the sliding member 18 is withdrawn. Whereas, while operating at a high speed and high load, introduction of the negative pressure is interrupted to cause the sliding member 18 to protruded. Thus, it becomes possible to improve the combustion characteristics and suction efficiency in response to the respective engine operating conditions.

Title: Painting method
Inventor: NOGUCHI SHINJI
IPC: B05D3/06
Filed: 1985-06-25
Abstract: PURPOSE:To form a uniform paint film having stable quality by enabling painting while inspecting painting irregularity at the time of painting, by painting a colorless transparent paint having a fluorescent substance added thereto and irradiating the formed paint film with ultraviolet rays. CONSTITUTION:When painting is performed by using a colorless transparent clear paint having a fluorescent substance, the fluorescent substance added to the paint emits a fluorescent color by the irradiation of ultraviolet rays and, therefore, ultraviolet rays with a wavelength of 220-352nm are allowed to irradiate the paint surface after painting. Whereupon, the area coated with the paint emits light and, if there is an area not coated with the paint, only said area emits no light and, therefore, the leaving of painting can be confirmed. Because the light emitting intensity of the fluorescent color changes by the difference of the thickness of the paint film, painting irregularity can be confirmed. As mentioned above, the coating state to the surface of an article to be painted at the time of painting can be visually observed, a leaving part of painting is eliminated and the paint film becomes uniform.

Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To provide a method by which an adhesive protection film can be separated easily from the surface of a device wafer, even when the device wafer is for smart cards. SOLUTION: In a method for stripping device wafer, a device wafer is stripped off an adhesive protection film, in such a way that the device wafer carrying the adhesive protection film stuck to its device pattern surface is held by a vacuum table chuck 2 which can make reciprocating motions in the lateral direction, in a state where the surface of the film 4 is sucked to the chuck 2 and a vacuum roll 3 which is rotatable about its axis of rotation is brought into contact with the surface of the wafer opposite to the film 4, while the chuck 2 is moved forward and rotated. Consequently, the device wafer is sucked to the surface of the roll 3 and stripped off the film 4 by leaving the film 4 on the chuck 2 following rotation of the roll 3.

Title: Image forming device
Inventor: KISHIDA TETSUO
IPC: G03G21/14
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To shorten first printing time and to prevent a problem such as image failure by altering a speed at which paper is carried according to an increase in the detected number of revolutions of a rotary polygon mirror. SOLUTION: Upon receiving a print instruction, a printer main body starts to drive a main motor for driving the paper transport system of a printer and a scanner motor for writing an image with a laser beam. The number of revolutions of the scanner motor is monitored until it exceeds, for example, 50% of the rated number of revolutions. In order to measure time needed to start up the rotation of the scanner motor, a timer is started. When it exceeds 50% of the rated number of revolutions, the timer is stopped, and the indication of the timer at that time is stored into a parameter T.  Then the feed of paper is started and in the case where the build up time T needed for the scanner motor to reach 50% to 80% of the rated number of revolutions is longer than predetermined time T0, the number of revolutions of the main motor is decreased by, for example, 10% in order to delay the transport of the paper.
