Filed: 1989-07-15
Abstract: PURPOSE:To obtain a photo current transformer which facilitates the mounting thereof on an existing breaker with a smaller size of a core by mounting a core on a conductor supported with an insulator to insert a photosensor into a hole formed in the core separately therefrom.

Abstract: PURPOSE:To prevent a temperature in a high pressure turbine exhaust hood from rising by instantly increasing a steam quantity flowing into a high pressure turbine more than a quantity for load corresponding to reheat steam pressure in starting the high-intermediate pressure turbine. CONSTITUTION:In the intermediate pressure starting method for a steam turbine comprising of a high pressure turbine 7 and an intermediate pressure turbine 8 driven by a reheat steam which is produced by reheating a steam after used for driving the high pressure turbine, a load is instantly increased from B% to A% (a load corresponding to pressure controlled by a low pressure bypass control valve 15) by quickly opening a steam adjust valve 3. Consequently, an exhaust pressure in the high pressure turbine 7 is increased at a dash above a reheat steam pressure to discharge the steam flowing into the high pressure turbine 7.

Title: Optical encoder
Inventor: KOSAKA FUSAO
IPC: G01D5/249
Filed: 1989-07-17
Abstract: PURPOSE:To obtain an encoder capable of encoding without being influenced by the amount of the phase shift by providing a code plate having different numbers of slits, two light sources the light intensity of which is changed between a sine wave and cosine wave, an adding means, a subtracting means and an HPF, and specifying the phase characteristic of a filter. CONSTITUTION:There are formed a slit array A of (n) slits (A...) on a larger radius of a code plate 4, and a slit array B of (n-1) slits (B1...) inside the slit array A. The light intensity of light sources 2,3 is modulated by sinomegat, cosomegat, respectively. The light passing through the array A is received by arrays 5a,6a, while the light passing through the array B is received by arrays 5b,6b. Accordingly, the phases phiA, phiB of the distribution of the light intensity are obtained. The phase phiA decides the measuring accuracy of the encoder, and it is selected by the phase phiB by which of the slits the waveform is formed. As the code plate 4 is rotated at a speed K, supposing that a carrier frequency fc=w/2pi, and a Doppler frequency fA =n.K, fB=(n-1).K, fC+fA and fC+fB are added to an HPF 20 and an HPF 22 respectively, thereby setting the phase characteristic of each HPF so as to obtain the phase rotation amount phi1 of a passing signal. At this time, (phia +phi1)-(phif+phi1)=phiab is obtained from an operating device 38, and influences by the phase shift of the HFP can be avoided.
