Title: Absolute encoder
Inventor: HAYASHI YOSHINORI
IPC: G01D5/243
Filed: 1988-09-02
Abstract: PURPOSE:To detect an absolute displacement from a reference position by converting a plurality of pitch signal level data to an absolute position data by the used of an absolute position data converting table. CONSTITUTION:When a magnetic recording medium 2 is rotated, detecting signals of phase A1, phase B1, phase A2 and phase B2 are obtained in accordance with the rotating angle of the medium from magnetic sensors 2a1, 2b1, 2a2 and 2b2, respectively. These detecting signals of phase A1, phase B1, phase A2 and phase B2 are converted to digital data Da1, Db1, Da2 and Db2 by A/D converters 31a, 31b, 32a and 32b, respectively. Then, the data Da1 and Db1, and Da2 and Db2 are converted to angle data theta1 and theta2 in angle calculating units 31c and 32c, respectively. The data theta1 and theta2 are converted to an absolute position data Dout by the use of an absolute position data converting table 5. An absolute displacement from a reference position is thus detected.

Title: Database updating device
Inventor: KUDO HIROTSUGU
IPC: G06F12/00
Filed: 1991-08-30
Abstract: PURPOSE:To reduce memory capacity by providing a first updating means, which updates a database by setting a new current memory when memory switching is made successful to all the cross connectors, and a second updating means to update the relevant part when memory recovery is failed to one part and not to update the relevant part when it is made successful. CONSTITUTION:When the memory switching is made successful to all the crosstalk connectors 20 by a recovery processing means 11, a first updating means 12 updates the data base for all the cross connectors 20 by setting the new current memory. On the other hand, when recovery 11 to one part of the cross connectors 20 is failed, a second updating means 13 updates the relevant part of the database for cross connector by setting the new current memory. When the recovery is made successful, however, the database for cross connector is not updated. Thus, since it is not necessary to hold a former memory in a controller, the memory capacity can be reduced.

Filed: 1988-09-05
Abstract: PURPOSE:To readily obtain a halogenated substance in high yield by treating an aromatic compound with a benzyltri-lower alkyulammonium trihalide in the presence of a Lewis acid. CONSTITUTION:An aromatic compound is treated with a compound expressed by the formula (R1 to R3 are 1-6C alkyl) X is halogen) in the presence of a Lewis acid (e.g., zinc chloride or bromide) to afford a halogenated substance. AlCl3 and AlBr3 in the Lewis acid are not preferred, since both will decompose the compound expressed by the formula.

Abstract: PURPOSE:To perform high-speed operation over a wide wavelength range by providing a light quantity control element which controls the transmission and cutoff of irradiated light by deforming a movable thin film with electrostatic force between charges in the movable thin film and a peripheral electric field under a vacuum. CONSTITUTION:When a switch 105 is set at a side A, the movable thin film 101 and a reverse surface electrode plate 103 are held at the same potential, a potential difference is generated between the movable thin film 101 and a top surface electrode plate 102, and the movable thin film 101 flexes to deform and enter a state 101.

Then when the switch 105 is changed over to a side B, attractive force between the movable thin film 101 and reverse surface electrode plate 103 operates thin time and the movable thin film 101 returns to a state 201. At this time, the reflected light 106 is cut off by the movable thin film and never reaches the light convergence part 107. The space 110 where the thin film 101 is held under a vacuum, so the atmospheric pressure which operates on the thin film 101 is removed, so that the thin film is easily peeled off the electrode plate 103.

Abstract: PURPOSE:To make it possible to detect the defective part in external appearance in the specified direction when this method is applied on the visual inspection of a product by comparing the characteristics on a reference image and an image to be compared by using a prediction operating expression indicating the associated degree between image data. CONSTITUTION:Reading scanning of a line sensor 10 is performed for a product in conveyance by (m) times. In a prediction filter 30, the prediction operation for the image data for every line which are obtained at the (m + 1)th time is performed. The difference between the prediction data at the (m + 1)th time and the actually obtained image data is computed. The result of the computation is outputted into a comparator 40 as a prediction error epsilon. In the comparator 40, the prediction error epsilon for every time is compared with a threshold value. When the prediction error is larger than the threshold value, the warning signal which indicates that there is the abnormal part in the image data that are obtained by the reading scanning from the first time to the (m + 1)th time is outputted. Even if the abnormal parts continue in the specified direction, the presence of the abnormal parts can be positively detected.

Filed: 1990-08-23
Abstract: PURPOSE:To prevent a motor fan from overheat and perform proper control against the causes of increase of suction resistance or the like by setting at least two set ranges of the output value of a detecting means to shorten a setting judging time within the set range corresponding to larger wind path resistance in a wind path. CONSTITUTION:A central processor 42 has an input limiting means 81 for reducing the input of a motor fan 12 to a set input value as a function on a program when the output value of a converting means 45 of a detecting means 46 exceeds a set value and a setting judging time elapses. An input limiting means 81 is incorporated in a calculation processing means 74 or data memory means 71. The data memory means 71 previously stores a set value of the output value of the detecting means 46 corresponding to negative pressure abnormally increased in a negative pressure space 26, the setting judging time and the output value of an output means 77 corresponding to the set input value. Two set values are set to the output value of the detecting means 46, corresponding to larger negative pressure and making the setting judging time shorter. Thus, since the input of the motor-fan 12 is not increased, but reduced when suction resistance is abnormally increased, the exothermic action of the motorfan 12 can be reduced.
