Patent JP-H08210605-A (JP)
Title: Water feed pump controller
Inventor: TAKAHASHI NOBUYUKI
IPC: F22D5/32
Filed: 1995-02-03
Abstract: PURPOSE: To stably control a water feed flow rate and prevent a disturbance from being applied to a boiler by changing the opening of a recirculation valve so as to maintain a minimum inlet flow rate in accordance with a recirculation valve opening command signal moderately and gradually changing without an abrupt change corresponding to a power quantity signal during low load. CONSTITUTION: When the load of a power plant starts to decrease, a water feed flow rate command signal QC decreases, and accordingly, an inlet flow rate detecting signal QR gradually decreases. At this time, the output VB of a recirculation valve opening command function generating means 31 gradually increases to an opening direction from a completely closed position depending on the decrease of a power quantity signal L. Thus, a high value selecting means 32 selects the output signal VB of the recirculation valve opening command function generating means 31 to have a recirculation valve opening command signal V. At this time, the decreasing speed of the power quantity signal L is low and the signal gradually decreases.  The increasing speed of the recirculation valve opening command signal V is also low and shifts so as to avoid a disturbance from being applied to a water feed flow rate signal QF. An inlet flow rate detecting signal QR does not become less than an inlet flow rate setting signal QT.

Title: Temperature control circuit
Inventor: MORI KEIICHI
IPC: G05D23/19
Filed: 1985-02-27
Abstract: PURPOSE:To attain a fail-safe system of a temperature control circuit as a whole by providing a temperature switch circuit which switches the set temperature level in response to the output pulse of a pulse generating circuit to a temperature detecting circuit together with a comparator which compares the set temperature value with the value of the temperature sensor. CONSTITUTION:A CPU 2 delivers the pulse signal of a fixed cycle through an output (a) and impresses it to a pulse transformer 3. The induced voltage of a secondary winding is rectified by a diode 4 and smoothed by a capacitor 5 to be impressed to a coil of a solenoid valve 6. When no pulse signal is avail able, the transformer 3 has no actuation any more. Then the valve 6 is closed. A temperature detecting circuit 18 compares the voltage divided potentials of a temperature sensor 7 with the reference set potential divided by resistances 21 and 22 through a comparator 23. Then the high and low signals are delivered to the CPU 2 with high and low temperatures respectively. Thus a resistance 26 is intermitted in parallel to a resistance 22 in response to the pulse signal. Then the relay potential eS is switched between eS1 and eS2.

Title: Preventing device of illegal access of ic card
Inventor: HAGIWARA ISAMU
IPC: G06F21/62
Filed: 1984-02-28
Abstract: PURPOSE:To prevent an illegal or erroneous access to a data memory area of an IC card and its illegal use by storing a sign for identifying an IC card in itself, checking the sign by the card itself with that transmitted from an IC card input device before access to the data memory area, and destructing the data stored in the IC card at the time of dissident signs. CONSTITUTION:A code a12 received by an IC card is checked to be coincident with the code which the IC card itself stores, and when they are dissident, the data which a ROM stores are destructed. The sign checking frequency is preset, and when they are coincident within the specific access frequency, access start OK data are transmitted to a side A of an input device. A sign access area consisting of a sign memory area stores a sign to identify the IC card and the sign illegal access frequency. Thus when the sign dissident frequency reaches the specific value at the time of inputting an IC card, storage data in the data memory area are destructed, and by checking codes at the time of access to the important data memory area data safety can be made more complete.
