Title: Overspeed protective device for motor
Inventor: TANAKA MASAO
IPC: H02P7/292
Filed: 1985-12-16
Abstract: PURPOSE:To make it possible to detect the overspeed in an inexpensive device by detecting the failure of the speed transmitter by using the existing pulse transmitting means to output the pulse signals with the frequency in proportion to the rotating speed of the generator. CONSTITUTION:A speed regulator 22 outputs the current command in accordance with the deviation of the output of a speed transmitter 5 from that of a speed setter 21. On the other hand, a magnetic sensor 12 outputs the pulse signal whenever a magnetic piece 11 fitted to the main shaft 7 comes close. An orientation stop control circuit 13 stops the main shaft 7 to the predetermined stopping position by inputting the output pulse of the magnetic sensor 12. The output pulse of the magnetic sensor 12 is converted into the voltage signal by a F/V converter 31. Comparators 32 and 35 transmit the failure of the speed transmitter 5 to an alarm circuit 38 when the voltage signal of each exceeds the set point and when the difference between the voltage signal and the output signal of the speed transmitter 5 exceeds the set point respectively.

Title: Orthogonal transformation encoder
Inventor: KAYABA MAKOTO
IPC: H04N19/134
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To improve image quality by correcting the transformation coefficient of a block under consideration based on the difference of the DC component coefficient of the transformation coefficient of the block under the consideration and the DC component coefficient of the block positioned near the block. SOLUTION: An orthogonal transformation part T generates the DC component coefficient by transforming the image data of the block under the consideration using DCT. A coefficient correction part R corrects the DC component coefficient of a DCT coefficient based on the level difference of the DC component coefficient and the DC component coefficient of the block adjacent to the block under consideration. As a discriminated result by a discrimination part R3, in the case that the level difference of the DC component coefficients does not exceed a prescribed value, a coefficient replacement part R4 outputs the DCT coefficient inputted from the transformation part T as it is to a post stage.  On the contrary, in the case that the level difference exceeds the prescribed value, the replacement part R4 replaces the DC component coefficient with a value for making the level difference by lower than the prescribed value. In such a manner, the correction part R replaces and corrects the DC component coefficient of the DCT coefficient generated by the transformation part T corresponding to the level difference.
