Title: Moving vector detecting method
Inventor: TAKAHASHI KIYOSHI
IPC: H04N19/513
Filed: 1988-03-17
Abstract: PURPOSE:To prevent mis-detection of a moving vector generated when the parallel movement of the entire picture is not generated by discriminating the effectiveness of a moving vector detected depending on the correlation of picture information from operating information of a camera and correcting the information as necessary. CONSTITUTION:A selection circuit 203 is a circuit selecting either a moving candidate vector 105 or a zero vector 202, and selects the moving candidate vector 105 when a switching control signal 209 being an output of a gate circuit 208 is logic 1 and selects the zero vector 202 when logic 0. Thus, in case of no pan and tilt operation moving the entire picture in parallel and in case of zooming, even if the movement candidate vector is not brought into the zero vector in mistake, the vector is corrected forcibly into the zero vector. Thus, mis-detection of the moving vector is prevented.

Title: Rotor for permanent magnet type electric rotating machine
Inventor: MIZUNO TAKAYUKI
IPC: H02K15/03
Filed: 1995-03-23
Abstract: PURPOSE: To obtain a rotor for permanent magnet type electric rotating machine in which the centrifugal strength is enhanced without sacrifice of electric characteristics by interposing a magnet between S pole core and N pole core and partially shifting the phase of the S pole core and N pole core in the circumferential direction on the surface of a rotor while superposing in the axial direction. CONSTITUTION: The rotor comprises an end part S pole core 21 made of a magnetic material, an intermediate S pole core 22, an end part N pole core 23, an intermediate N pole core, and a disc magnet 25 magnetized with different polarities on the opposite sides thereof. The surface parts 21b, 22b of the S pole cores 21, 22 and the surface parts 23b, 24b of the N pole cores 23, 24 present alternately in the circumferential direction while being superposed in the axial direction. Since the magnet 25 and the rotor are not split in the circumferential direction and no reinforcing member is provided in the axial direction, centrifugal strength can be enhanced and a countermeasure against damage of the magnet 25 can be taken easily. Furthermore, the electric characteristics are not deteriorated because the equivalent air gap can be decreased and the effective core length can be shortened.

Title: Mechanical translation system
Inventor: MORINO KOJI
IPC: G06F17/28
Filed: 1988-03-17
Abstract: PURPOSE:To prevent a context error of the translation of a sentence caused by a tentative subject when the translation cannot be expressed in a passive voice by expressing the sentence in an active voice by inserting a symbol which substitutively indicates the omitted subject into the position of the subject. CONSTITUTION:A translation preparing section 4 retrieves a translation word dictionary 5 and put a translation word to the internal expression of the translation of a sentence to be translated. Then the section 4 discriminates whether or not the sentence to be translated has a subject and, when the sentence has a subject, the section 4 prepares the translation of the sentence to be translated. When the sentence has no subject, the section 4 discriminates whether or not the translation can be expressed in a passive voice from the grammatical character of the verb selected as the predicate verb of the translation by paying attention to the verb. If the translation can be expressed in a passive voice, the translation is prepared. When the discriminated result is negative, the translation is prepared by inserting a symbol which substitutively indicates the omitted subject into the translation. The translation thus prepared is outputted to a translation outputting section 6. Therefore, occurrence of an error caused by the substitution of an omitted subject in a Japanese sentence which has no subject and cannot be translated into a sentence of a passive voice when the Japanese sentence is translated into a sentence written in a foreign language can be prevented.

Then single-wavelength interference is produced by putting the filter 28 on the lamp 21 and the intensities of interference fringes at each measuring point is measured and used as the intensities of interference fringes at initial detecting points.  Then the intensities of interference fringes at three or more spots in the one-period range of the intensities of interference fringes are detected from the initial detecting points by minutely displacing a reference mirror 24 at every measuring point and the phases of the initial detecting points are found from the minutely displaced amount at every measuring point. Thereafter, interference fringe generating positions are detected by means of a length measuring instrument 30 at every measuring point by removing the filter 28 and displacing the detector 20 in the direction Za and the relative height between the measuring points is roughly calculated. Then the order of interference fringes corresponding to the relative height is found and the relative height between the measuring points is calculated from the order and the phases of the initial detecting points.
