Title: Image forming/storing device
Inventor: WATANABE GIICHI
IPC: G06F17/30
Filed: 1993-05-24
Abstract: PURPOSE:To obtain a satisfactory index image despite the presence of plural production forms of the index information. CONSTITUTION:The production form of the set index information is decided, and the reduction ratio of the image information equivalent to one page and selected as the index information is decided based on the production form of the index information. Thus the image information is reduced in the decided reduction ratio so that the new index information is produced. Furthermore the variable magnifying power of the image information can be changed for production of the index information in accordance with the format, the image density, etc., of the image information. Then the size of the image to be formed is previously recognized for the reference index information, and the variable magnifying power of other index information can be controlled based on the recognized size of the image.

Title: Grinding method for farady rotor
Inventor: TAKAHASHI TSUTOMU
IPC: B24B1/00
Filed: 1987-05-19
Abstract: PURPOSE:To automatically detect fine waviness on the machine surface of a workpiece during machining, by a method wherein a vibration sensor is secure to a tool post, and a converter to convert acceleration of vibration detected by the vibration sensor into a voltage and a comparator to compare the output voltage of the converter with an arbitrary set value are provided. CONSTITUTION:During a tuning work, the magnitude of the initial speed of vibration of a tool 3 and a tool post 4, generated during machining, is differed due to a change in impurity in a workpiece 2, a defect in crystal, tool wear, or pitching, or resistance during convey-out of chips. As acceleration of the vibration is decreased, fine waviness on a machine surface is decreased, and an excellent surface is formed. Thus, by mounting a vibration sensor 5 on a tool post 4 of a precision lathe 1, vibration during machining is detected, a vibration output is converted into acceleration by means of a converter 6, and the magnitude of acceleration is outputted as the intensity of a voltage. By comparing the output voltage with a set value by means of a comparator 7, it is evaluated whether fine waviness on the surface of the workpiece 2 is allowable.

Title: Positioning control method
Inventor: TAKEUCHI KIYOKAZU
IPC: B23Q15/24
Filed: 1982-07-13
Abstract: PURPOSE:To eliminate inherent oscillations generated in positioning control, by supplying the signal obtained by a detector provided at the load side of a DC servomotor to the input part of a motor control circuit via a digital processing feedback loop. CONSTITUTION:The signals corresponding to the number of revolutions of a DC servomotor 4 are negatively fed back to a pulse shaping circuit 5 via a tachometer 9 and a rotary encoder 10 to perform positioning of a feed nut 2 to an X table 1. A shift degree of the nut 2 is detected by a magnetic sensor 11, and the digital pulse signal is supplied to a CPU12 via an amplifier 13. The CPU12 calculates the deviation between a set driving pulse and a pulse corresponding to the input distance data on the basis of the programming contents set previously. Then the CPU12 decides the resolution to be corrected and feeds it into the circuit 5. Therefore the positioning accuracy of the nut 2 is decided by the detecting sensitivity of the sensor 11, and the pulse resolution is decided and corrected successively by the CPU12. Thus the over-speed produced under the speed control is damped to eliminate the natural oscillations.
