Title: Method for controlling steam turbine
Inventor: TAKAHASHI TATSUO
IPC: F01D17/24
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To suppress the output fluctuation of a turbine when operational mode is changed over. SOLUTION: When a load limitation setting apparatus signal S9 becomes a lower value than a mechanical speed governing control signal S15 at time t3, a speed governing control signal S28 is tuned OFF, a speed governing operational mode signal P6a at the time of cooperative operation is turned OFF and a load limiting operational mode signal S13 is turned ON.  A one-shot signal S32 is turned ON one-shot, a speed governing control operational mode signal (S19) is turned OFF one-shot and a turbine required signal S1 is equalized in a moment with the load limitation setting apparatus signal S9 therefore, even though an error exists between a synchronism setting apparatus signal S2 and the mechanical speed governing control signal S15, the synchronism setting apparatus signal S2 and the mechanical speed governing control signal S15 can be changed over by suppressing the output fluctuation of a turbine when operational mode is changed over.

Title: Carriage control circuit for magnetic disk device
Inventor: MINAGAWA KEIJI
IPC: G11B21/08
Filed: 1987-02-17
Abstract: PURPOSE:To prevent a ready-off trouble when a manual is under rezero operation by providing a means to prevent the execution of the rezero operation for a specified time after a manual switch is set at a wait mode. CONSTITUTION:A monostable vibrator 12 and an OR gate 11 are provided between a rezero switch 13 and a control circuit 10. Namely, when the rezero switch 13 is turned to ON, a signal L is outputted from the OR gate 11, and at the same time, the monostable vibrator 12 operates and outputs the signal L to the OR gate 11 for prescribed time (one shot time). As a result, while the monostable vibrator 12 outputs the signal L, the output of the OR gate 11 is held at the signal L. Accordingly, by setting one shot time to be the sufficient time for the carriage 4 to reach a structural stop position SP, even if the rezero switch 13 is turned to OFF while the carriage 4 moves to an inner circumference direction, it does not shift to the rezero operation, but starts the rezero operation after the expiration of the one shot time. Accordingly, a malfunction when the manual is rezero can be prevented.

Title: Optical pickup for optical disc
Inventor: SHIKADA MINORU
IPC: G11B7/135
Filed: 1982-03-02
Abstract: PURPOSE:To reduce the weight of the optical system part of an optical pickup to be  driven by an actuator to about 1/5 the weight of conventional optical pickups and to  reduce the size thereof by separating a laser light source and a photodetector from  said optical system part, connecting both by means of optical fibers and transmitting  light beams between the same. CONSTITUTION:The exit light 5 from the 1st optical fiber 4 passes through a calcite  plate 6 of which the polarizing direction of ordinary rays is matched to the direction  of the linear polarizing direction thereof, whereafter the light is converted to parallel beams with the 1st combined lens 7. The parallel beams are focused with the 2nd  combined lens 9, and the focused light is made incident to an optical disc 10. Incident  light 11 is reflected as signal light 12 having recording information by the disc 10, and  returns to the lens 9 and a 1/4 wavelength plate 8. The polarizing direction of the  signal light 12 past the plate 8 intersects orthogonally the polarizing direction of the  light 5 and since the signal light 12 propagates as abnormal rays in the plate 6, the  light is separated from the optical path of the light 5 and is coupled to the 2nd optical  fiber 13. The 2nd optical fiber 13 has the 1st-4th core parts, and the 1st- the 4th  coupled beams of light are made incident to a photodetector 26 having the 1st-4th  photodetecting surfaces.

Filed: 1984-02-23
Abstract: PURPOSE:To obtain an optical information processor capable of satisfactory searching action by producing a focus search signal having high linearity through an LPF after generating digitally a triangular wave voltage signal with use of a shift register. CONSTITUTION:When an output control signal OCV2 is delivered from a focus detecting circuit 14 after application of a power supply, a shift register SL is driven while the signal OCV2 is kept at a high level.

While signals D-F are supplied in the same way to a non-reverse input terminal (+) of the circuit 25. The output V25 of the circuit 25 is turned into a triangular wave signal and then to a focus search signal FSC having a linear change after passing through an LPF26 to be supplied to a focus actuator coil 19. Thus it is possible to obtain an optical information processor which is capable of an extremely satisfactory focus searching action.

Filed: 1993-02-23
Abstract: PURPOSE: To reduce the distortion of the luminance and color of a reconstructed picture by multiplexing the data indicating videos containing digital luminance and color data into a multiplexed data block having a prescribed length. CONSTITUTION: Compressed luminance data and compressed color data are supplied to a control logic and counter 100. The counter 100 accumulates the multiplexed data in output data buffers 102 and 104. When the multiplexed data are accumulated in the buffers 102 and 104, the addresses of luminance and color data elements are fetched from address data as start addresses 110 and stored in the buffer 104. The counter 102 holds the count value of the data quantity stored in the buffer 102 and, when a prescribed size of compressed luminance and color data is stored in the buffer 102, the counter 100 generates a pointer 112 which indicates the position of the boundary between the luminance data and color data in a multiplexed data block and temporarily stores the pointer 112 in the buffer 104. Finally, the counter 100 couples the contents of both buffers 102 and 104 with each other.

Title: Semiconductor storage device
Inventor: KONISHI YASUHIRO
IPC: H01L21/8242
Filed: 1988-02-16
Abstract: PURPOSE:To reduce the influence to detection caused by changes in the potential of memory cells accompanied by the elapse of time so as to reduce the electric current at the time of waiting states and, at the same time, to realize highly reliable refreshing operations by changing the potential at each point of a bit line when the electric charge of one of the memory cells is read out to another bit line paired to the first mentioned bit line. CONSTITUTION:When writing is made in a memory cell 1a, a transistor Q1 is turned on and the potential Vcc of a bit line BL is impressed on a capacitor C1. After the transistor Q1 is turned off, the bit line BL and its paired bit line -BL are equalized to the potential of Vcc/2 by means of bit line equalizing signals phiEQ and the potential is maintained. On the other hand, capacitors C3 and C4 of a dummy cell 4 are conducted to an earthing power source Vss and their potential becomes 0V. When a refreshing mode is set, the capacitors C3 and C4 and bit lines BL and -BL are conducted and the potential of the bit lines BL and -BL becomes lower than the Vcc/2. Therefore, even if the refreshing period is extended, decline of the detection margin can be prevented and the reliability can be improved.
