Title: Speed feedback circuit
Inventor: OOTSUKI HARUAKI
IPC: G05B19/23
Filed: 1980-08-27
Abstract: PURPOSE: To realize a speed feedback short in the time delay without realizing a speed detector, by providing a means which measures the time when the control variable displace for a given amount and calculates the speed, in a speed feedback circuit of a position servo mechanism.  
     CONSTITUTION: A speed feedback circuit 4 consists of a subtraction circuit 3, approximate fractional function generating element 7, counter element 8 and clock oscillator 9. In a reversible counter 5, a position target value x is inputted to an addition input terminal and the position Y is given to the subtraction input terminal, and a position deviation E is outputted from them. The element 8 counts a clock output C from an oscillator 9 and renews the count by pulses from an incremental encoder 6 and stores the count value. An element 7 divides quantized units with time interval of pulses produced at the section of quantization from the encoder 6 to obtain the speed.

Title: Video signal processing circuit
Inventor: HAYASHI YOSHIKAZU
IPC: H04N5/44
Filed: 1992-05-11
Abstract: PURPOSE:To prevent S/N from being deteriorated even when a 2nd LPF is integrated into an IC as a nonlinear active element by disposing a 1st LPF suppressing a higher frequency triangle noise component than a MUSE signal frequency band behind an FM demodulation circuit. CONSTITUTION:A 2nd intermediate frequency signal being the output of a turning circuit 10 is FM-demodulated with an FM demodulation circuit 11, and an FM detection signal in which a video signal and an audio signal subcarrier are subjected to frequency division multiplexing is obtained. The FM detection signal has a so-called triangle noise signal in which the noise components are increased as the frequency gets higher and a 1st LPF 30 eliminates a high frequency noise component. Thus, the generation of undesired noise in a video signal band due to the saturation of a 2nd LPF 23 whose frequency is 4.5MHz constituted of an active element built in an IC due to out-band noise is avoided by disposing the 1st LPF 30 interrupting the noise power in advance at the out-band of the video signal behind the FM demodulation circuit 11.

Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To prevent oil from leaking from a change gear system side to an expansion machine side by arranging an expansion machine generating a positive pressure between a change gear system and a compressor. SOLUTION: A turbine 7 generating a positive pressure is arranged between a speed-up mechanism 5 and a compressor 9. By this arrangement oil leakage from the speed-up mechanism 5 side to a turbine 7 side is prevented from occurring and because oil is not included in cool air, injection of the cool air directly to a load becomes possible and a cooling system is formed in an open cycle. Therefore, because oil removal from the cool air by using an oil separator is not required, increase of cost can be avoided and an evaporator is not required to be used, and a simple, compact and light-weighted structure can be accomplished and cost is reduced and decrease in efficiency can be avoided. The number of parts can be reduced by arranging the speed-up mechanism 5, the turbine 7 and the compressor 9 on an impeller 13.

Filed: 1989-05-15
Abstract: PURPOSE:To rapidly stop a steam turbine without considering critical speed of a turbine shaft by forming a jet passage in a reverse direction to rotational direction on the turbine shaft facing to a nozzle. CONSTITUTION:A nozzle 15 is provided on an outlet side of a steam pipe 17 arranged on a turbine shaft seal part 13. A jet passage 14 is formed on a turbine shaft 1 facing to the nozzle 15. The jet passage 14 is a groove formed on the whole circumference of the turbine shaft 1, while being inclined in a reverse direction of the rotation of the turbine shaft 1. Steam is blown from the nozzle 15 through the steam pipe 17 to the jet passage 14 in the reverse direction of the rotation of the turbine shaft 1, so that the steam shows controlling perfor mance during inversion thereat. The rotational speed of the turbine shaft 1 is rapidly decreased without setting the pressure in the steam turbine to an atmospheric pressure. It is therefore possible to rapidly stop the steam turbine without considering the critical speed of the turbine shaft 1.
