Title: Manufacture of transversely stretched film
Inventor: FUJII YASUHIRO
IPC: B29C53/04
Filed: 1990-11-16
Abstract: PURPOSE:To prevent flaws or gear marks from being generated on the surface of a film by a method wherein, when an unstretched film is subjected to a wrinkle treatment in longitudinal direction and then transversely stretched, height of a gear tooth at the center of a horizontally long gear-shaped roll for use in wrinkle treatment is made lower than that at opposite ends of said roll. CONSTITUTION:Height (f) of gear teeth at the central section of a gear-shaped roll is made lower than the height (c) of gear teeth at the opposite ends (d) of the roll, preferably the height (f) of the teeth corresponding to 20-90% of the width of film in the central section thereof is made lower than that (c) at the opposite ends (d). If the width in which lower teeth are provided exceeds 90%, the central section of film contact the central teeth, causing gear marks to be generated. The height (f) in the central section is preferred to be 50-95% of the height (c). If 30% or lower, wrinkles in the center of unstretched film do not take uniform wave shapes, resulting in uneven orientation and if 95% or higher, heated film slightly hangs down and the central section (e) contact the teeth, causing gear marks to be generated. And shapes of teeth ends in the section where the height of teeth is low are preferably made round and formed into an arc shape.

Title: Image processing method, image processor and recording medium
Inventor: YAMAGATA HIDEAKI
IPC: G06T7/60
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To complement a void in a character image with a black pixel at high speed in a preprocessing when the image inputted from a scanner is inputted to character recognition software. SOLUTION: It is judged whether a void complement processing is executed on an input image or not. When resolution is <=300 dpi and the resolutions of length and breadth are different from each other, the void complement processing is not executed. A white run and a black run are extracted in respective lines and the black run and the white run for only two lines are necessary to be extracted in a picture processor. Since the black run connected to a left side does not exit in a white run 21, the processing is shifted to the processing of a next white run 22. Since the black run 11 including the range of the white run exists in the white run 22, a threshold A on the length of the connected black run is obtained from the length of the white run 22. Since the length of the white run 22 is '2', threshold = 10 is obtained from a table.  The total length of the black run 11, the black run 21 and the black run 2, which are connected to the white run 21, is obtained. It becomes 12+5+18=35. Since 35>10 (=A), the white run 22 is judged to be void and it is substituted for a black pixel.

Abstract: PURPOSE:To make it possible to implement a highly accurate sensor characterized by excellent acceleration detecting speed even under severe temperature conditions, by providing a layer which surrounds a piezoelectric element and composed of a material having a large heat conductivity, and providing a layer composed of a material having a small heat conductivity at the outside of said layer. CONSTITUTION:A planar piezoelectric element 1 is composed of two planar piezoelectric elements 1a and 1b and a bonding agent, which sticks both elements 1a and 1b. The upper and lower parts of the element 1 is held with frames 5a and 5b of 42% Ni-Fe, whose thermal expansion coefficient is approximately equal to that of the element 1. The element 1 is fixed so that the frames are symmetrical with respect to the central plane of the element 1. The device is fixed in a box shaped copper case 6, which has a large heat conductivity and is symmetrical at the upper and lower parts and the right and left parts. Thus, the gradient of temperature depending on places is decreased. The outside is covered with plastics 7 having a small heat conductivity. Even if the outside temperature is changed, the heat gradient is made large, and the temperature change due to external causes is decreased. An aluminum thin film 8 having surface gloss is formed on the outside of the plastics 7. The most part of radiation from an external heat source is reflected. Thus, transfer of heat from the outside is largely decreased.

Filed: 1987-12-08
Abstract: PURPOSE:To surely recognize a flow in a duct line by inserting a wire rod into the duct line and deciding a flow-down direction of the wire rod which flows down along a flow of a fluid. CONSTITUTION:First of all, a fire hydrant 3 is opened, and in a state that vinyl tube 6 inserted through the inside of a city water pipe 1, a wire rod 5 is blown out into the city water pipe 1 by pressure and allowed to flow down by a flow of water 2. Next, a gold plating bare wire part 8 of the wire rod which has flowed down is allowed to correspond to one of detecting terminals 10a, 10b, an electric resistance between them is measured by a resistance meter 11. In this case, electric resistance values of both of them become different values, and the value of an electric resistance detected in one terminal 10a corresponding to the bare wire part 8 becomes smaller than the value of an electric resistance detected by the other detecting terminal. Accordingly, based on the value of the electric resistance which is detected, a flow-down direction of the wire rod 5 can be decided, and this flow-down direction of the wire rod which has been decided can be detected as a flow direction of the water 2.
