Filed: 1991-08-29
Abstract: PURPOSE:To make a converter accomplish its high-frequency operation and make its size small, by preventing the biased excitations of transformers, and by reducing the ripple currents of dividing capacitors. CONSTITUTION:When MOS FET's 11a, 12b are turned on and off concurrently, by a load current fed from an input voltage source 13, via a transformer 15a, fed is a power from the MOS FET 11a to the secondary side of the transformer 15a. At the same time, the load current becomes a charging current of a capacitor 17a, and the round loop of a current is formed. But, since the MOS FET 12b is turned on and off synchronizing with the MOS FET 11a too, the charging current to the capacitor 17a is made to flow, as the discharging current from the capacitor 17a, into the connection point of a capacitor 16b and a capacitor 17b, via the connection point of a capacitor 16a and the capacitor 17a. Then, by the discharging current, via a transformer 15b, a power is fed to the secondary side of the transformer 15b.

Title: Controller for ac excited synchronous machine
Inventor: BANDO AKIRA
IPC: H02P9/42
Filed: 1989-09-22
Abstract: PURPOSE:To suppress abrupt voltage change upon interruption of an AC excited synchronous machine from an AC system by providing a second phase generating means for generating a sine wave having predetermined frequency, a phase switching means, and a command value switching means for holding a quadrature current component command value at a predetermined level, and operating means for performing switching between a phase signal and a command value simultaneously. CONSTITUTION:Upon closing of contact X26, a slip phase operating unit 25 holds the slip phase output to start DC excited operation. Upon closing of contact 28, a quadrature current command switch 27 brings the quadrature current command to zero which is then fed to an exciting current controller 14. Upon closing of contact Y31, a slip phase switch 30 connects the output from a two- phase oscillator 29 to the exciting current controller 14. Consequently, an AC excited synchronous machine 5 enters into synchronous operation mode upon opening/closing of the contacts X26 and Y31 while enters into a mode for controlling only the direct axis current upon closing of contact Z. By such arrangement, abrupt voltage change can be suppressed upon interruption of the synchronous machine from an AC system.

The error between outputs of the circuits 1021-102n and the input signal is calculated by an error calculation circuit, errors are compared and an error comparator circuit 104 decides an optimum block length of a minimum error. Then a selector 105 is controlled and a coding signal or the like with an optimum block length stored in the device 101 is selected. Since the coding and compression are applied in the optimum block length, the information quantity is compressed to improve the coding quality, while satisfying reciprocal requirements such as resolution and tracing property change in an input signal.

IPC: G01N21/01
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To obtain a fluorescent microscope by which stray light inside a microscope is extremely reduced and by which a single fluorescent molecule can be easily observed. SOLUTION: Light having wide spectrum emitted from an illuminating light source 11 is condensed by a condenser lens 12, reflected by a reflecting mirror 13, then divided into reflected light and transmitted light by a 45-degree incident band reflecting and simulating light filter 14. The transmitted light which is unnecessary for fluorescent observation and harmful is guided to a light trap 16, and quenched. The light with stimulated wavelength band reflected by the filter 14, that is, the stimulated light is reflected by a dichroic mirror 18, passes through an objective lens 20, and reaches an observation sample 10. The light made incident on the trap 16 is substantially quenched, the light having wavelength other than that of the stimulated light is substantially eliminated, so that it does not become the stray light.  Therefore, the stray light can be eliminated to a level that the single fluorescent molecule can be easily observed.

Abstract: PURPOSE:To enable a bath taking person to feel an appropriate temperature by a method wherein if a bath water level is lower than a designated water level, the bath is heated up to a temperature lower than a designated temperature and in turn if the water level exceeds the designated water level, the bath is heated up to the designated temperature. CONSTITUTION:A target temperature To is set lower than a designated temperature Ts by a water level discriminating means 16 and a target temperature changing-over means 17 before taking a bath and if the water level is lifted up upon taking the bath, the target temperature To is changed over to the designated temperature Ts with a signal from the water level discriminating means 16. Since a hot bath temperature is Ts-2, an additional controlling means 19 is operated to start an additional heating operation. As the water level is lowered from the bath tub, the target temperature To is returned to a value Ts-2. If a hot water feeding temperature is lower than the target temperature To, the additional heating is started to keep the target temperature To.
