Title: Linear type ultrasonic motor
Inventor: TAKAGI SHIGEYUKI
IPC: H02N2/00
Filed: 1989-06-22
Abstract: PURPOSE:To obtain a linear type ultrasonic motor with a large thrust and a wide speed control range by generating the elliptic motion of a standing wave through a longitudinal vibration piezoelectric element and a slip vibration piezoelectric element to take out a linear output. CONSTITUTION:If a high frequency voltage B is applied between electrode 6A, 6B of a transverse vibration unit 4, a reverse piezoelectric action is generated in slip vibration piezoelectric elements 5A, 5B so that a vibrator 9 is displaced to the right. Then, the reverse piezoelectric action is also generated in longitudinal vibration piezoelectric elements 2A, 2B and the vibrator 9 is displaced upward while decreasing in the displacement to the right-hand direction so as to be pressure-welded to an output member 12. After that, the vibrator 9 reaches the lower longitudinal limit position transversely in the center. Thereafter, when a series of similar displacements of the vibrator 9, i.e., an elliptic motion is repeated, the output member 12 moves linearly and continuously.

Title: Device for taking in/out of thin plate
Inventor: TAJIMA KENICHI
IPC: B65G1/04
Filed: 1984-07-31
Abstract: PURPOSE:To prevent materials from being damaged and from being housed in erroneously in a device for taking in and out thin plates such as a substrate by arranging a pair of guides in such a manner that they can be opened at a position near the foremost point of a grip which is movable back and forth as required and is used to hold the thin plate, allowing the grip to pass through. CONSTITUTION:A grip 12 is allowed to face a specific housing section 2 by means of an overhead crane and a lifting carriage, then a laterally moving table is brought closely to a rack 1. This allows the leading edge of a thin plate W which is held by the grip 12, to be guided into a gap 25 between two guides 13a and 13b through oblique guide surfaces 24 of the guides 13a and 13b permitting the thin plate to go into the housing section 2. Subsequently, the guides 13a and 13b are opened by an air motor (not shown) allowing the grip 12 to pass through so that the thin plate W is housed in the housing section 2 by the grip 12. The thin plate can be taken out by reversing the above said procedure. This configuration enables the thin plate to go into the housing section while it is guided by the guides preventing the thin plate from being damaged and being erroneously housed in.

Title: Pneumatic force balance servomechanism
Inventor: KITAMURA KENSHIYOU
IPC: G01L13/00
Filed: 1982-09-20
Abstract: PURPOSE:To obtain a small-sized differential pressure indicator with good characteristics by constituting and balancing a pneumatic servomechanism which inputs the force of an object of measurement, and eliminating the abrasion influence of an indication part by the strong driving force of the servomechanism. CONSTITUTION:When differential pressure is applied between a high and a low pressure introducing openings from a differential pressure detection part such as an orifice, sealed liquid 3a moves to a low-pressure room on the right-hand side and diaphragms 1 and 3 are displaced to right. The displacement rotates a shaft 41 through a transmission shaft 4 to displace the lower end of a force transmission rod 42 to left, so an operating screw 5 leaves a flapper 6, which then approaches a nozzle 9. Consequently, the back pressure of the nozzle rises and is transmitted to a bellows 9, which extends to right to displace the upper part of an operating lever 10 arcuately, tensing a feedback spring 11. Consequently, the force transmission rod 42 is drawn back to right through the feedback spring 11. The tip of the operating screw 5, therefore, contacts the flapper 6 again and a balance state is entered while the gap between the flapper 6 and nozzle 7 is expanded to the original state. Thus, the displacement of the diaphragms 1 and 2 are almost eliminated.

Title: Image processor
Inventor: KAWADA TOSUKE
IPC: G06T7/00
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To inspect the size and defects of an object of inspection whose position is not fixed. SOLUTION: An image of a component is picked up by an image pickup device and the obtained image data are processed to measure the position deviation from a reference position and the angle of rotation an the size from a reference rotational position. According to the measurement results, negative seek lines 312, 313, and 314 are set in parallel to the outside to constitute an inspection template 315. The negative seek lines are lines which are anticipated not to cross an edge of the image, i.e., a part where optical characteristics in the image do not change abruptly. However, if the component has a cut, the negative seek line passes an image 311 of the cut and, for example, the negative seek line 314 crosses the edge. From to this fact, it is decided that the component has the cut as a defect and therefore is nonconforming.  Further, the presence of burrs can be inspected by setting negative seek lines outside the image 310 of the component.

Title: Gas sampling device for dust or gas containing much dust and vapor
Inventor: UCHIDA KAORU
IPC: G01N1/22
Filed: 1984-08-03
Abstract: PURPOSE:To make the gas sampling possible which is stable for a long period of time by providing a rinsing device for dust-proofing to a gas conduit. CONSTITUTION:A probe 1 positioned on the outside of a furnace wall 5 and the gas conduit 2 are internally heated and insulated by a heater 7 and a heat insulating material 8 so as not to be cooled down to the dew point temp. of a sampling gas or below and therefore the sticking of dust to the inside wall of the probe 1 and the conduit 2 as a result of dew condensation is obviated and even if the dust sticks to the inside wall, the dust is kept in a dry state and therefore the dust can be blown off and removed into the furnace from the top end 1A of the probe simply by purging periodically air through a purging port. Rinsing water flows constantly over the entire surface of the rinsing device 4 and therefore the dust entering the device 4 is delivered to the outside through an ejector 3 without sticking thereto. The sticking of the dust owing to the scattering of the ejector driving water is thus prevented and the long-term stable gas sampling is made possible.

Title: Intermediate tone picture binarizing processing system
Inventor: YAMAZAKI NOBUHISA
IPC: H04N1/40
Filed: 1988-06-30
Abstract: PURPOSE:To prevent the deterioration in the quality of a picture by adding multi-value expression intermediate tone picture data sequentially in the unit of picture element to be inputted, outputting the carry in each excess of a prescribed value as level 1 of a binary expression pseudo intermediate tone picture data and the other as level 0 and transferring the remaining result of addition to the addition of next picture elements. CONSTITUTION:A multi-value expression intermediate tone data obtained by applying raster scanning to an original picture is given to an input register 12 in the unit of picture elements sequentially. An adder 14 adds the content of the input register 12 to the content of an addition result register 13 and outputs a binary expression pseudo intermediate tone picture data 15 of level 1 in the case of production of a carry and of level 0 without any carry production. Moreover, the result of addition (remainder) except the carry is written in the addition result register 13 and used for the addition with the next input picture data. Thus, the multi-value expression intermediate tone picture data inputted in each line of raster scanning are added consecutively and the result is converted into a binary expression pseudo intermediate tone picture data. Thus, the reproducibility of an intermediate tone picture is improved.

Title: Method and device for inspecting seaming
Inventor: KURAMOCHI SADAO
IPC: B21D51/30
Filed: 1989-06-26
Abstract: PURPOSE:To enable rapid and sure inspection of whether the seamed state of a container having a metallic cover is right or not by detecting an amount of recess at the bottom part of a plastic container body with a position sensor. CONSTITUTION:First, the container 20 having a metallic cover manufactured by seaming in a vacuum state is mounted on a mounting base 11 so that the metallic cover 21 comes to the lower part. Then, the position of the bottom part 24b of the container body 24 is detected. The inner part of the container 20 having a metallic cover forms a vacuum when it is seamed in a vacuum state, consequently, when this container having a metallic cover is taken out into the atmosphere, the soft plastic container body 24 in the container 20 having a metallic cover is recessed and deformed. Since this recessed deformation is generated remarkably on the bottom part 24b of the container body 24, the seaming state between the flange part 25 of the container body 24 and the circumferential edge part 22 of the metallic cover 21 can be detected by detecting the position of the bottom part 24.
