IPC: H03H9/09
Filed: 1982-02-02
Abstract: PURPOSE:To improve the shock resistance and at the same time to increase the lifetime of a piezoelectric oscillator, by providing a preventing member at an inside part consisting of a base part and a case so as to avoid contact between the piezoelectric oscillator and the inner wall of said case as well as to reduce the vibrations due to an impact of dropping, etc. CONSTITUTION:A preventing member 31 is set at an inside part consisting of a base part 24 and a case 32 so as to avoid contact between a piezoelectric oscillator 20 and the inner wall of the case 32. The main body of the oscillator 20 is attached to a communication device, etc. Thus the oscillator 20 has vibrations owing to the impact of its attachment and then touches protecting parts 31c and 31c of the member 31. the vibrations of the oscillator 20 are absorbed by the protecting parts and foot parts 31b and 31b. Thus the impact force is reduced, and therefore the oscillator 20 never touches the case 32. This prevents the breakdown of the oscillator 20 and increases the lifetime of the oscillator 20.

Title: Image recognition and alignment device
Inventor: KINUMEGAWA ISAO
IPC: G06T7/00
Filed: 1993-02-02
Abstract: PURPOSE:To set a dictionary area capable of providing high alignment accuracy to an image processing part which can be memory-set by memory-setting an arbitrary pattern on a board surface where these exists no dummy pattern around there as a reference pattern for board alignment. CONSTITUTION:An arbitrary pattern is stored as a temporary dictionary area W1 and the arbitrary pattern and nearby patterns are read, thereby determining a matching rate with the temporary dictionary area W1. A value, which is close to +1, is adopted as the matching rate of the arbitrary pattern. On the other hand, the matching rate of the nearby patterns is lowered than that of the arbitrary pattern. When the difference is small, however, the arbitrary pattern resembles the nearby patterns. When the difference is large, there exists no resemblance between them. Therefore, if only a pattern whose matching rate is large, is avaliable near the arbitrary pattern, the arbitrary pattern is set as a reference pattern or more specifically the pattern is memory-set as a regular dictionary area and used for alignment.

Abstract: PURPOSE:To prevent a bridge from being made between the thin iron sheets of core of an eletric machine in the cutting of the core, by causing the cutting route of the tool to differ between the roughing and finishing processes in the cutting so that burr made during the roughing processing is removed during the finishing process. CONSTITUTION:When the cylindrical surface 8 of the rotary core 1 of a rotary electric machine, which is made of thin iron sheets 5, is to be roughed, the core 1 is rotated around its axis 9 in the direction of an arrow 2 and a tool 10 is so positioned that the tool extends perpendicularly to the axis 9 and acts to cut the surface 8 upwards. The tool 10 is moved along the axis 9 in the direction of an arrow 11 to rough the cylindrical surface 8 of the core 1 on a route like a left-handed screw. To finish the cylindrical surface 8, the core 1 is rotated in the opposite direction and a finishing tool is so mounted as to cut the surface downwards. The finishing tool is moved in the same direction as in the roughing to cut the cylindrical surface 8 on a route like a right-handed screw. In the finishing, burr made during the roughing is removed to prevent production of a bridge between the thin iron sheets 5 to avoid the increase in the iron loss.

Abstract: PROBLEM TO BE SOLVED: To decolorize a formed image and to make the remaining image forming material invisible by the naked eye by heating the image forming material incorporating coloration compound, developer and erasing agent and developing a color on a recording medium at a temperature higher than the fusion point of the erasing agent so that the image may be erased. SOLUTION: The image is erased by heating the image forming material incorporating the coloration compound, the developer and the erasing agent and developing the color on the recording medium at the temperature higher than the fusion point of the erasing agent. In this image erasing device, paper is carried in the device with its image formed surface up and heated by a heat roller 11a, then roughed by 1st and 2nd surface roughing rollers 12a and 13a. The image on the paper is excellently erased by heating by the roller 11a.
