Filed: 1988-09-19
Abstract: PURPOSE:To improve the cooling efficiency of a high pressure casing and enable shortening of the cooling period by sending a cooling air to a high pressure turbine between the inner casing, and the rotor and outer casing under controlling the flow rate and temperature. CONSTITUTION:The cooling air from an air pump 8 is subjected to temperature regulation in a heater 10 and introduced in a high pressure turbine exhaust pipe by a connecting pipe 19. One of the branched cooling air is passed between an inner casing 1 and a rotor 5 and released to the atmosphere from a main steam stop valve drain pipe 11a through a steam governing valve 11. On the other hand, the cooling air passed through the space a, b rooms between the inner casing 1 and the outer casing 2 is run through a cooling air passing port 2a provided on the outer casing 2 and released to the atmosphere through a cooling air low rate control valve 21. Hence, the high pressure turbine is cooled efficiency from the both inner and outer sides of the inner case 1, and the cooling period can be shortened.

Abstract: PURPOSE:To obtain a reference value input device of a parallel control system which can expand a single system into plural systems. CONSTITUTION:A reference value input device consists of a command part A and the control parts B1 and B2 which are connected to each other via a data line 1 and a data request line 3. The part A does not accept the date request signals from the parts B1 and B2 during the transmission of the reference value data. Then the part A always transmits the initial state data except the reference value data that are transmitted when the data request signals are received from both parts B1 and B2. The parts B1 and B2 always monitor the line 1 to detect the changes of the initial state data and the reference value data and read the reference value data to decide a correct or wrong state of this data. Then the correct data is requested again if the wrong reference value data is decided.

Title: Transversal filter control method
Inventor: SAKANE TOSHIRO
IPC: H04B3/04
Filed: 1988-09-16
Abstract: PURPOSE:To suppress the generation of an error in the main signal system of a filter generated when the reset setting/release of the filter is performed by relaxing quick change in the characteristic of a transmission path by performing the reset setting/release of a tap by setting a time differently sequentially. CONSTITUTION:The control of a tap coefficient is stopped sequentially in time order advancing from the most remote peripheral taps T-n, Tn to a center tap To at the time of reset setting of the tap, and the control of the tap coefficient of the center tap To is stopped at the final stage. Thereby, since the reset of the tap is performed sequentially starting from the peripheral taps by which insignificant influence is given and the center tap To with significant influence is reset finally, no quick change is generated in transmission characteristic by a reset operation, and the generation of the error can be suppressed. Meanwhile, the stoppage of the control of the tap coefficient is released starting from the center tap To at the time of performing the reset release, and it is performed on the remote peripheral taps sequentially. In such a way, the operation of the filter can be performed smoothly even in this case.

Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To obtain a control method of a fluidized bed type garbage incinerator which allows controlling of an amount of steam generated stably to a target value. SOLUTION: In an actual plant A, garbage is burned within a sand layer fluidized by blowing primary air and steam generated by waste heat obtained is circulated through the sand layer to perform a heating. In this case, an actually measured value of an operation value of the primary air to time immediately before is substituted into a model M indicating a relationship between the operation value of the primary air prepared and the amount of steam generated to compute the amount yM(k) of steam generated at the present time and the operation value u(k) of the primary air at the present time is determined by a forecast control method based on an error Δy of the computed value yM(k) from an actually measured value y(k) of the amount of the steam generated at the present time, an orbit yd (τ+k+L) of a desired value of steam generated and a total control value Σu(k-j)  of the primary air in the past. This always allows controlling of the amount of steam generated stably to a target value.

Title: Liquid crystal display element
Inventor: MORIIZUMI YASUE
IPC: G02F1/1335
Filed: 1994-09-28
Abstract: PURPOSE: To provide a high quality liquid crystal display element having a good appearance for a display screen and excellent visibility by extremely lowering surface reflection. CONSTITUTION: Reflected light to be emitted to the outside of a liquid crystal display element through an optical anisotropic element 2 is shifted by 1/4 wavelength when it passes through the optical anisotropic element 2 once, and is shifted by 1/4 wavelength when it is reflected on BM (a light shielding film 3) and passes through the optical anisotropic element 2 again, and as a result, rotatory polarization by 90 degrees equivalent to 1/2 wavelength in total is carried out, so that straight polarized light is directed in the direction orthogonal to that of the straight polarized light which passed through the polarizing plate 12a at first. Therefore, this reflected light cannot pass through the polarizing plate 12a.  In this way, reflected light reflected on BM (light shielding film 3), which is made of metallic material, for example, and has a high light reflecting property, in a non-picture element part is not emitted theoretically to an observation side, and in fact, the reflected light is scarcely emitted to the observation side.

Title: Method of driving pulse motor
Inventor: TANAKA HIRONORI
IPC: H02P8/14
Filed: 1986-09-30
Abstract: PURPOSE:To prevent the noise of a pulse motor and to suppress its vibration, by automatically changing over from a driving method in full step to a driving method in half step in the resonance frequency region. CONSTITUTION:The rotation of a pulse motor 1 is transmitted to a paper carrier roller 3 through a transfer means 2 such as a gear, a belt, etc. A control circuit 4 controls the pulse motor 1, which is driven by a drive circuit 5. When there is no driving frequency of the pulse motor 1 near the resonance frequency region, a driving method in full step is adopted. When the driving frequency gets close to the resonance frequency region, the driving frequency is doubled and that the driving method is changed over into half step one. The noise is thereby prevented which occurs in driving the pulse motor in the resonance frequency region and the vibration of the pulse motor is hence suppressed.
